What Flexible Dieting Really Means

When Flexibility Is The Dish Of The Day
This is Alan Aragon. Notwithstanding not being a “Dr. Alan Aragon”, he’s a research scientist with dozens of peer-reviewed nutrition science papers to his name, as well as being a personal trainer and fitness educator. Most importantly, he’s an ardent champion of making people’s pursuit of health and fitness more evidence-based.
We’ll be sharing some insights from a book of his that we haven’t reviewed yet, but we will link it at the bottom of today’s article in any case.
What does he want us to know?
First, get out of the 80s and into the 90s
In the world of popular dieting, the 80s were all about calorie-counting and low-fat diets. They did not particularly help.
In the 90s, it was discovered that not only was low-fat not the way to go, but also, regardless of the diet in question, rigid dieting leads to “disinhibition”, that is to say, there comes a point (usually not far into a diet) whereby one breaks the diet, at which point, the floodgates open and the dieter binges unhealthily.
Aragon would like to bring our attention to a number of studies that found this in various ways over the course of the 90s measuring various different metrics including rigid vs flexible dieting’s impacts on BMI, weight gain, weight loss, lean muscle mass changes, binge-eating, anxiety, depression, and so forth), but we only have so much room here, so here’s a 1999 study that’s pretty much the culmination of those:
Flexible vs. Rigid Dieting Strategies: Relationship with Adverse Behavioral Outcomes
So in short: trying to be very puritan about any aspect of dieting will not only not work, it will backfire.
Next, get out of the 90s into the 00s
…which is not only fun if you read “00s” out loud as “naughties”, but also actually appropriate in this case, because it is indeed important to be comfortable being a little bit naughty:
In 2000, Dr. Marika Tiggemann found that dichotomous perceptions of food (e.g. good/bad, clean/dirty, etc) were implicated as a dysfunctional cognitive style, and predicted not only eating disorders and mood disorders, but also adverse physical health outcomes:
Dieting and Cognitive Style: The Role of Current and Past Dieting Behaviour and Cognitions
This was rendered clearer, in terms of physical health outcomes, by Dr. Susan Byrne & Dr. Emma Dove, in 2009:
❝Weight loss was negatively associated with pre-treatment depression and frequency of treatment attendance, but not with dichotomous thinking. Females who regard their weight as unacceptably high and who think dichotomously may experience high levels of depression irrespective of their actual weight, while depression may be proportionate to the degree of obesity among those who do not think dichotomously❞
Aragon’s advice based on all this: while yes, some foods are better than others, it’s more useful to see foods as being part of a spectrum, rather than being absolutist or “black and white” about it.
Next: hit those perfect 10s… Imperfectly
The next decade expanded on this research, as science is wont to do, and for this one, Aragon shines a spotlight on Dr. Alice Berg’s 2018 study with obese women averaging 69 years of age, in which…
In other words (and in fact, to borrow Dr. Berg’s words from that paper),
❝encouraging a flexible approach to eating behavior and discouraging rigid adherence to a diet may lead to better intentional weight loss for overweight and obese older women❞
You may be wondering: what did this add to the studies from the 90s?
And the key here is: rather than being observational, this was interventional. In other words, rather than simply observing what happened to people who thought one way or another, this study took people who had a rigid, dichotomous approach to food, and gave them a 6-month behavioral intervention (in other words, support encouraging them to be more flexible and open in their approach to food), and found that this indeed improved matters for them.
Which means, it’s not a matter of fate or predisposition, as it could have been back in the 90s, per “some people are just like that; who’s to say which factor causes which”. Instead, now we know that this is an approach that can be adopted, and it can be expected to work.
Beyond weight loss
Now, so far we’ve talked mostly about weight loss, and only touched on other health outcomes. This is because:
- weight loss a very common goal for many
- it’s easy to measure so there’s a lot of science for it
Incidentally, if it’s a goal of yours, here’s what 10almonds had to say about that, along with two follow-up articles for other related goals:
Spoiler: we agree with Aragon, and recommend a relaxed and flexible approach to all three of these things
Aragon’s evidence-based approach to nutrition has found that this holds true for other aspects of healthy eating, too. For example…
To count or not to count?
It’s hard to do evidence-based anything without counting, and so Aragon talks a lot about this. Indeed, he does a lot of counting in scientific papers of his own, such as:
and
The effect of protein timing on muscle strength and hypertrophy: a meta-analysis
…as well as non-protein-related but diet-related topics such as:
But! For the at-home health enthusiast, Aragon recommends that the answer to the question “to count or not to count?” is “both”:
- Start off by indeed counting and tracking everything that is important to you (per whatever your current personal health intervention is, so it might be about calories, or grams of protein, or grams of carbs, or a certain fat balance, or something else entirely)
- Switch to a more relaxed counting approach once you get used to the above. By now you probably know the macros for a lot of your common meals, snacks, etc, and can tally them in your head without worrying about weighing portions and knowing the exact figures.
- Alternatively, count moderately standardized portions of relevant foods, such as “three servings of beans or legumes per day” or “no more than one portion of refined carbohydrates per day”
- Eventually, let habit take the wheel. Assuming you have established good dietary habits, this will now do you just fine.
This latter is the point whereby the advice (that Aragon also champions) of “allow yourself an unhealthy indulgence of 10–20% of your daily food”, as a budget of “discretionary calories”, eventually becomes redundant—because chances are, you’re no longer craving that donut, and at a certain point, eating foods far outside the range of healthiness you usually eat is not even something that you would feel inclined to do if offered.
But until that kicks in, allow yourself that budget of whatever unhealthy thing you enjoy, and (this next part is important…) do enjoy it.
Because it is no good whatsoever eating that cream-filled chocolate croissant and then feeling guilty about it; that’s the dichotomous thinking we had back in the 80s. Decide in advance you’re going to eat and enjoy it, then eat and enjoy it, then look back on it with a sense of “that was enjoyable” and move on.
The flipside of this is that the importance of allowing oneself a “little treat” is that doing so actively helps ensure that the “little treat” remains “little”. Without giving oneself permission, then suddenly, “well, since I broke my diet, I might as well throw the whole thing out the window and try again on Monday”.

Tasty Versatile Rice
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
In the nearish future, we’re going to do some incredible rice dishes, but first we need to make sure we’re all on the same page about cooking rice, so here’s a simple recipe first, to get technique down and work in some essentials. We’ll be using wholegrain basmati rice, because it has a low glycemic index, lowest likelihood of heavy metal contamination (a problem for some kinds of rice), and it’s one of the easiest rices to cook well.
You will need
- 1 cup wholegrain basmati rice (it may also be called “brown basmati rice“; this is the same)
- 1 1/2 cups vegetable stock (ideally you have made this yourself from vegetable offcuts that you saved in the freezer, then it will be healthiest and lowest in sodium; failing that, low-sodium vegetable stock cubes can be purchased at most large supermarkets. and then made up at home with hot water)
- 1 tbsp extra virgin olive oil
- 1 tbsp chia seeds
- 1 tbsp black pepper, coarse ground
- 1 tsp turmeric powder (this small quantity will not change the flavor, but it has important health benefits, and also makes the rice a pleasant golden color)
- 1 tsp garlic powder
- 1 tsp yeast extract (this gently improves the savory flavor and also adds vitamin B12)
- Optional small quantity of green herbs for garnish. Cilantro is good (unless you have the soap gene); parsley never fails.
This is the ingredients list for a super-basic rice that will go with anything rice will go with; another day we can talk more extensive mixes of herbs and spice blends for different kinds of dishes (and different health benefits!), but for now, let’s get going!
Method
(we suggest you read everything at least once before doing anything)
1) Wash the rice thoroughly. We recommend using a made-for-purpose rice-washing bowl (like this one, for example), but failing that, simply rinse it thoroughly with cold water using a bowl and a sieve. You will probably need to rinse it 4–5 times, but with practice, it will only take a few seconds per rinse, and the water will be coming up clear.
2) Warm the pan. It doesn’t matter for the moment whether you’re using an electronic rice cooker, a stovetop pressure cooker, electronic pressure cooker, or just a sturdy pan with a heavy lid available, aside from that if it’s something non-stovetop, you now want it to be on low to warm up already.
3) Separately in a saucepan, bring your stock to a simmer
4) Put the tbsp of olive oil into the pan (even if you’re confident the rice won’t stick; this isn’t entirely about that) and turn up the heat (if it’s a very simple rice cooker, most at least have a warm/cook differentiation; if so, turn it to “cook”). You don’t want the oil to get to the point of smoking, so, to test the temperature as it heats, flick a single drop of water from your fingertip (you did wash your hands first, right? We haven’t been including that step, but please do wash your hands before doing kitchen things) into the pan. If it sizzles, the pan is hot enough now for the next step.
5) Put the rice into the pan. That’s right, with no extra liquid yet; we’re going to toast it for a moment. Stir it a little, for no more than a minute; keep it moving; don’t let it burn! If you try this several times and fail, it could be that you need a better pan. Treat yourself to one when you get the opportunity; until then, skip the toasting part if necessary.
6) Add the chia seeds and spices, followed by the stock, followed by the yeast extract. Why did we do the stock before the yeast extract? It’s because hot liquid will get all the yeast extract off the teaspoon 🙂
7) Put the lid on/down (per what kind of pan or rice cooker you are using), and turn up the heat (if it is a variable heat source) until a tiny bit of steam starts making its way out. When it does, turn it down to a simmer, and let the rice cook. Don’t stir it, don’t jiggle it; trust the process. If you stir or jiggle it, the rice will cook unevenly and, paradoxically, probably stick.
8) Do keep an eye on it, because when steam stops coming out, it is done, and needs taking off the heat immediately. If using an automatic rice cooker, you can be less attentive if you like, because it will monitor this for you.
Note: if you are using a simple pan with a non-fastening lid (any other kind of rice cooking setup is better), more steam will escape than the other methods, and it’s possible that it might run out of steam (literally) before the rice is finished. If the steam stops and you find the rice isn’t done, add a splash of water as necessary (the rice doesn’t need to be submerged, it just needs to have liquid; the steam is part of the cooking process), and make a note of how much you had to add (so that next time you can just add it at the start), and put it back on the heat until it is done.
9) Having taken it off the heat, let it sit for 5 minutes (with the lid still on) before doing any fluffing-up. Then you can fluff-up and serve, adding the garnish if you want one.
Enjoy!

Colloidal Gold’s Impressive Claims
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
All That Glitters…
Today we’ll be examining colloidal gold supplementation.
This issue of 10almonds brought to you by the writer suddenly getting lots of advertisements for this supplement. It’s not a new thing though, and has been around in one form or another since pretty much forever.
Colloidal gold is…
- Gold, as in the yellow metal
- Colloidal, as in “very tiny insoluble particles dispersed though another substance (such as water)”
What are the claims made for it?
Honestly, just about everything is claimed for it. But to go with some popular claims:
- Reduces inflammation
- Supports skin health
- Boosts immune function
- Combats aging
- Improves cognitive function
So, what does the science say?
Does it do those things?
The short and oversimplified answer is: no
However, there is a little bit of tangential merit, so we’re going to talk about the science of it, and how the leap gets made between what the science says and what the advertisements say.
First… What makes gold so special, in general? Historically, three things:
- It’s quite rare
- It’s quite shiny
- It’s quite unreactive
- The first is about supply and demand, so that’s not very important to us in this article.
- The second is an aesthetic quality, which actually will have a little bit of relevance, but not much.
- The third has been important historically (because it meant that shiny gold stayed shiny, because it didn’t tarnish), and now also important industrially too, as gold can be used in many processes where we basically need for nothing to happen (i.e., a very inert component is needed)
That third quality—its unreactivity—has become important in medicine.
When scientists need a way to deliver something (without the delivering object getting eaten by the body’s “eat everything” tendencies), or otherwise not interact chemically with anything around, gold is an excellent choice.
Hence gold teeth, and gold fillings, by the way. They’re not just for the bling factor; they were developed because of their unreactivity and thus safety.
So, what about those health claims we mentioned above?
Here be science (creative interpretations not included)
The most-backed-by-science claim from that list is “reduces inflammation”.
Websites selling colloidal gold cite studies such as:
Gold nanoparticles reduce inflammation in cerebral microvessels of mice with sepsis
A promising title!The results of the study showed:
❝20 nm cit-AuNP treatment reduced leukocyte and platelet adhesion to cerebral blood vessels, prevented BBB failure, reduced TNF- concentration in brain, and ICAM-1 expression both in circulating polymorphonuclear (PMN) leukocytes and cerebral blood vessels of mice with sepsis. Furthermore, 20 nm cit-AuNP did not interfere with the antibiotic effect on the survival rate of mice with sepsis.❞
That “20 nm cit-AuNP” means “20 nm citrate-covered gold nanoparticles”
So it is not so much the antioxidant powers of gold being tested here, as the antioxidant powers of citrate, a known antioxidant. The gold was the carrying agent, whose mass and unreactivity allowed it to get where it needed to be.
The paper does say the words “Gold nanoparticles have been demonstrated to own important anti-inflammatory properties“ in the abstract, but does not elaborate on that, reference it, or indicate how.
Websites selling colloidal gold also cite papers such as:
Anti-inflammatory effect of gold nanoparticles supported on metal oxides
Another promising title! However the abstract mentions:
❝The effect was dependent on the MOx NPs chemical nature
[…]
The effect of Au/TiO2 NPs was not related to Au NPs size❞
MOx NPs = mineral oxide nanoparticles. In this case, the gold was a little more than a carrying agent, though, because the gold is described and explained as being a catalytic agent (i.e., its presence helps the attached mineral oxides react more quickly).
We said that was the most-backed claim, and as you can see, it has some basis but is rather tenuous since the gold by itself won’t do anything; it just helps the mineral oxides.
Next best-backed claim builds from that, which is “supports skin health”.
Sometimes colloidal gold is sold as a facial tonic. By itself it’ll distribute (inert) gold nanoparticles across your skin, and may “give you a healthy glow”, because that’s what happens when you put shiny wet stuff on your face.
Healthwise, if the facial tonic also contains some of the minerals we mentioned above, then it may have an antioxidant effect. But again, no minerals, no effect.
The claim that it “combats aging” is really a tag-on to the “antioxidant” claim.
As for the “supports immune health” claim… Websites selling colloid gold cite studies such as:
To keep things brief: gold can fight infectious diseases in much the same way that forks can fight hunger. It’s an inert carrying agent.
As for “improves cognitive function”? The only paper we could find cited was that mouse sepsis study again, this time with the website saying “researchers found that rats treated with colloidal gold showed improved spatial memory and learning ability“ whereas the paper cited absolutely did not claim that, not remotely, not even anything close to that. It wasn’t even rats, it was mice, and they did not test their memory or learning.
Is it safe?
Colloidal gold supplementation is considered very safe, precisely because gold is one of the least chemically reactive substances you could possibly consume. It is special precisely because it so rarely does anything.
However, impurities could be introduced in the production process, and the production process often involves incredibly harsh reagents to get the gold ions, and if any of those reagents are left in the solution, well, gold is safe but sodium borohydride and chloroauric acid aren’t!
Where can I get some?
In the unlikely event that our research review has given you an urge to try it, here’s an example product on Amazon

Cognitive Enhancement Without Drugs
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Cognitive Enhancement Without Drugs
This is Elizabeth Ricker. She’s a Harvard-and-MIT-trained neuroscientist and researcher, who now runs the “Citizen Science” DIY-neurohacking organization, NeuroEducate.
Sounds fun! What’s it about?
The philosophy that spurs on her research and practice can be summed up as follows:
❝I’m not going to leave my brain up to my doctor or [anyone else]… My brain is my own responsibility, and I’m going to do the best that I can to optimize it❞
Her goal is not just to optimize her own brain though; she wants to make the science accessible to everyone.
What’s this about Citizen Science?
“Citizen Science” is the idea that while there’s definitely an important role in society for career academics, science itself should be accessible to all. And, not just the conclusions, but the process too.
This can take the form of huge experiments, often facilitated these days by apps where we opt-in to allow our health metrics (for example) to be collated with many thousands of others, for science. It can also involve such things as we talked about recently, getting our own raw genetic data and “running the numbers” at home to get far more comprehensive and direct information than the genetic testing company would ever provide us.
For Ricker, her focus is on the neuroscience side of biohacking, thus, neurohacking.
I’m ready to hack my brain! Do I need a drill?
Happily not! Although… Bone drills for the skull are very convenient instruments that make it quite hard to go wrong even with minimal training. The drill bit has a little step/ledge partway down, which means you can only drill through the thickness of the skull itself, before the bone meeting the wider part of the bit stops you from accidentally drilling into the brain. Still, please don’t do this at home.
What you can do at home is a different kind of self-experimentation…
If you want to consider which things are genuinely resulting in cognitive enhancement and which things are not, you need to approach the matter like a scientist. That means going about it in an organized fashion, and recording results.
There are several ways cognitive enhancement can be measured, including:
- Learning and memory
- Executive function
- Emotional regulation
- Creative intelligence
Let’s look at each of them, and what can be done. We don’t have a lot of room here; we’re a newsletter not a book, but we’ll cover one of Ricker’s approaches for each:
Learning and memory
This one’s easy. We’re going to leverage neuroplasticity (neurons that fire together, wire together!) by simple practice, and introduce an extra element to go alongside your recall. Perhaps a scent, or a certain item of clothing. Tell yourself that clinical studies have shown that this will boost your recall. It’s true, but that’s not what’s important; what’s important is that you believe it, and bring the placebo effect to bear on your endeavors.
You can test your memory with word lists, generated randomly by AI, such as this one:
You’ll soon find your memory improving—but don’t take our word for it!
Executive function
Executive function is the aspect of your brain that tells the other parts how to work, when to work, and when to stop working. If you’ve ever spent 30 minutes thinking “I need to get up” but you were stuck in scrolling social media, that was executive dysfunction.
This can be trained using the Stroop Color and Word Test, which shows you words, specifically the names of colors, which will themselves be colored, but not necessarily in the color the word pertains to. So for example, you might be shown the word “red”, colored green. Your task is to declare either the color of the word only, ignoring the word itself, or the meaning of the word only, ignoring its appearance. It can be quite challenging, but you’ll get better quite quickly:
The Stroop Test: Online Version
Emotional Regulation
This is the ability to not blow up angrily at the person with whom you need to be diplomatic, or to refrain from laughing when you thought of something funny in a sombre situation.
It’s an important part of cognitive function, and success or failure can have quite far-reaching consequences in life. And, it can be trained too.
There’s no online widget for this one, but: when and if you’re in a position to safely* do so, think about something that normally triggers a strong unwanted emotional reaction. It doesn’t have to be something life-shattering, but just something that you feel in some way bad about. Hold this in your mind, sit with it, and practice mindfulness. The idea is to be able to hold the unpleasant idea in your mind, without becoming reactive to it, or escaping to more pleasant distractions. Build this up.
*if you perchance have PTSD, C-PTSD, or an emotional regulation disorder, you might want to talk this one through with a qualified professional first.
Creative Intelligence
Another important cognitive skill, and again, one that can be cultivated and grown.
The trick here is volume. A good, repeatable test is to think of a common object (e.g. a rock, a towel, a banana) and, within a time constraint (such as 15 minutes) list how many uses you can think of for that item.
Writer’s storytime: once upon a time, I was sorting through an inventory of medical equipment with a colleague, and suggested throwing out our old arterial clamps, as we had newer, better ones—in abundance. My colleague didn’t want to part with them, so I challenged him “Give me one use for these, something we could in some possible world use them for that the new clamps don’t do better, and we’ll keep them”. He said “Thumbscrews”, and I threw my hands up in defeat, saying “Fine!”, as he had technically fulfilled my condition.
What’s the hack to improve this one? Just more volume. Creativity, as it turns out, isn’t something we can expend—like a muscle, it grows the more we use it. And because the above test is repeatable (with different objects), you can track your progress.
And if you feel like using your grown creative muscle to write/paint/compose/etc your magnum opus, great! Or if you just want to apply it to the problem-solving of everyday life, also great!
In summary…
Our brain is a wonderful organ with many functions. Society expects us to lose these as we get older, but the simple, scientific truth is that we can not only maintain our cognitive function, but also enhance and grow it as we go.

What Happens To Your Body When You Do 100 Glute Bridges Every Day
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Not just for a sculpted butt:
Benefits
With consistent daily glute bridge practice, you may expect:
- Rounder, toned butt: targets the gluteus maximus, toning and lifting the butt for a rounder appearance.
- Improved posture: strengthens glutes to support the spine and pelvis, alleviating lower back and hip pain. Stretches tight hip flexors from prolonged sitting.
- Stronger lower back: glutes support the lower back and spine, reducing pain and making it easier to lift heavy objects. Activating the glutes transfers force from legs to core, preventing injuries.
- Stronger knees: stabilizes the knee joint and promotes alignment by engaging glutes, hamstrings, and quadriceps, reducing knee pain.
- Sculpted hamstrings: contracts hamstrings during lifts for strength, while stretching them on the way down increases flexibility.
- Increased hip flexibility: strengthens muscles around the hip joint, improving mobility and counteracting tight hips from sedentary habits.
- Reduced back pain: strengthens glutes to correct pelvic tilt and reduce strain on the lower back.
- Faster running speed: improves hip extension, strengthens hamstrings, and activates the gluteus medius for better running power and balance.
- Enhanced strength training performance: strengthens glutes, back, and knees, improving performance in exercises like squats and deadlifts.
As for how to get going, the video offers the following very sound advice: begin with 25–30 reps per session and gradually increase to sets of 100 daily. It should take about 5 minutes (that’s 3 seconds per repetition). Results can be seen in as little as 2 weeks, with significant changes after a month of consistent practice.

Carbonated Water: For Weight Loss, Satiety, Or Just Gas?
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
There are two main mechanisms of action by which sparkling water is considered to help satiety and/or weight loss; they are:
- It “fills us up” such that we feel fuller sooner, and thus eat less, and thus (all other things being equal) perhaps lose weight
- The carbon dioxide is absorbed into the bloodstream, where (as a matter of chemistry) it improves glucose metabolism, thus lowering blood sugars and indirectly leading (potentially) to weight loss, but even if not, lowered blood sugars are good for most people most of the time, right?
However, there are just a few problems:
Full of gas?
Many people self-report enjoying sparkling water as a way to feel fuller while fasting (or even while eating). However, the plural of “anecdote” is not “data”, so, here be data… Ish:
❝In order to determine whether such satiating effects occur through oral carbonic stimulation alone, we conducted modified sham-feeding (SF) tests (carbonated water ingestion (CW), water ingestion (W), carbonated water sham-feeding (CW-SF), and water sham-feeding (W-SF)), employing an equivalent volume and standardized temperature of carbonated and plain water, in a randomized crossover design.
Thirteen young women began fasting at 10 p.m. on the previous night and were loaded with each sample (15ºC, 250 mL) at 9 a.m. on separate days. Electrogastrography (EGG) recordings were obtained from 20 min before to 45 min after the loading to determine the power and frequency of the gastric myoelectrical activity. Appetite was assessed using visual analog scales. After ingestion, significantly increased fullness and decreased hunger ratings were observed in the CW group. After the load, transiently but significantly increased fullness as well as decreased hunger ratings were observed in the CW-SF group. The powers of normogastria (2-4 cpm) and tachygastria (4-9 cpm) showed significant increases in the CW and W groups, but not in the CW-SF and W-SF groups. The peak frequency of normogastria tended to shift toward a higher band in the CW group, whereas it shifted toward a lower band in the CW-SF group, indicating a different EGG rhythm.
Our results suggest that CO2-induced oral stimulation is solely responsible for the feeling of satiety.❞
~ Dr. Maki Suzuki et al.
Now, that’s self-reported, and a sample size of 13, so it’s not the most airtight science ever, but it is at least science. Here’s the paper, by the way:
Oral Carbonation Attenuates Feeling of Hunger and Gastric Myoelectrical Activity in Young Women
Here’s another small study with 8 people, which found that still and sparkling water had the exact same effect:
Effect of carbonated water on gastric emptying and intragastric meal distribution
However, drinking water (still or sparkling) with a meal will not have anywhere near the same effect for satiety as consuming food that has a high water-content.
See also: Some Surprising Truths About Hunger And Satiety ← our main feature in which we examine the science of volumetrics, including a study that shows how water incorporated into a food (but not served with a food) decreases caloric intake.
As an aside, one difference that carbonation can make is to increase ghrelin levels—that’s the hunger hormone (the satiety hormone is leptin, by the way). This one’s a rat study, but it seems reasonable that the same will be true of humans:
…which is worth bearing in mind even if you yourself are not, in fact, a male rat.
The glucose guzzler?
This one has simply been the case of a study being misrepresented, for example here:
Fizzy water might aid weight loss by providing a small boost to glucose uptake and metabolism
The idea is that higher levels of carbon dioxide in the blood mean faster glucose metabolism, which is technically true. Now, often “technically true” is the best kind of true, but not here, because it’s simply not useful.
In short, we produce so much carbon dioxide as part of our normal respiratory processes, that any carbon dioxide we might consume in a carbonated water is barely a blip in the graph.
Oh, and that article we just linked? Even within the article, despite running with that headline, the actual scientists quoted are saying such things as:
❝While there is a hypothetical link between carbonated water and glucose metabolism, this has yet to be tested in well-designed human intervention studies❞
~ Professor Sumantra Ray
Note: the word “hypothetical” means “one level lower than theoretical”. This is very far from being a conclusion.
And the study itself? Wasn’t even about carbonated water, it was about kidney dialysis and how the carbon dioxide content can result in hypoglycemia:
The mechanism of hypoglycemia caused by hemodialysis
…which got referenced in this paper (not a study):
Can carbonated water support weight loss?
…and even that concluded:
❝CO2 in carbonated water may promote weight loss by enhancing glucose uptake and metabolism in red blood cells.
However, the amount is so small that it is difficult to expect weight loss effects solely from the CO2 in carbonated water.
Drinking carbonated water may also affect blood glucose measurements.❞
Note: the word “may”, when used by a scientist and in the absence of any stronger claims, means “we haven’t ruled out the possibility”.
What breaking news that is.
Stop the press! No, really, stop it!
So… What does work?

Severe Complications for Pregnant Veterans Nearly Doubled in the Last Decade, a GAO Report Finds

Series: Post-Roe America:Abortion Access Divides the Nation
After the Supreme Court overturned Roe v. Wade, ending nearly 50 years of federal protection for abortion, some states began enforcing strict abortion bans while others became new havens for the procedure. ProPublica is investigating how sweeping changes to reproductive health care access in America are affecting people, institutions and governments.
Over the past decade, the rate of veterans suffering severe pregnancy complications has risen dramatically, a new federal report found.
Veterans have raced to the hospital with dangerous infections, kidney failure, aneurysms or blood loss. They’ve required hysterectomies, breathing machines and blood transfusions to save their lives. Between 2011 and 2020, 13 veterans died after such complications.
The report found that among people getting health care benefits through the Department of Veterans Affairs, the rate of severe complications nearly doubled during that time, from about 93 per 10,000 hospitalizations in 2011 to just over 184 per 10,000 hospitalizations in 2020. Black veterans had the highest rates.
The report, which was put together by the Government Accountability Office, also made recommendations for reducing the problem, which focus on conducting more routine screenings throughout pregnancy and in the postpartum period.
“It is imperative that the VA help ensure veterans have the healthiest pregnancy outcomes possible,” the report said, highlighting the increasing number of veterans using the agency’s maternity benefits as well as the troublesome complication rates faced by Black women.
The report’s findings are an unfortunate trend, said Alyssa Hundrup, director of health care at the GAO. The office analyzed data on 40,000 hospitalizations related to deliveries paid for by the VA. It captures a time period before 21 states banned or greatly restricted abortion and the military was thrust into a political battle over whether it would pay for active service members to travel for abortion care if a pregnancy was a risk to their health.
Hundrup, who led the review, said the analysis included hospital records from days after delivery to a year postpartum. The report was mandated after Congress passed a law in 2021 that aimed to address the maternal health crisis among veterans. The law led to a $15 million investment in maternity care coordination programs for veterans.
The report recommended that the VA analyze and collect more data on severe complications as well as data on the mental health, race and ethnicity of veterans who experience complications to understand the causes behind the increase and the reasons for the disparity. The report also states that oversight is needed to ensure screenings are being completed.
Studies show there’s a connection between mental health conditions and pregnancy-related complications, VA officials said.
The report recommended expanding the screening questions that providers ask patients at appointments to glean more information about their mental health, including anxiety and PTSD symptoms. It urged the VA to review the data more regularly.
“You don’t know what you don’t measure,” Hundrup said in an interview with ProPublica.
The VA health system, which historically served a male population, does not provide maternity care at its facilities. Instead, the agency has outsourced maternity care. But when patients were treated by those providers, the VA failed to track whether they were getting screened for other health issues and mental health problems.
Officials hope the improved data collection will help the VA study underlying issues that may lead to complications. For example, do higher rates of anxiety have a connection to rates of high blood pressure in pregnant people?
VA officials are working with a maternal health review committee to monitor the data as it is gathered. The agency recently conducted its first review of data going back five years about pregnancy-related complications, said Dr. Amanda Johnson, acting head of the VA’s Office of Women’s Health, who is overseeing the implementation of the report’s recommendations.
The VA has created a dashboard to monitor pregnant veterans’ health outcomes. The VA’s data analysis team will also examine the impact of veterans’ ages on complications and whether they differ for people who live in urban and rural areas.
VA officials will begin to review mental health screenings conducted by maternal care coordinators in March. The coordinators advocate for veterans, helping them between health care visits, whether their providers are inside or outside the VA.
Johnson said that reducing racial and ethnic disparities is a priority for the agency. In 2018, ProPublica published “Lost Mothers,” a series that shed light on the country’s maternal health crisis. Studies have shown that in the general population, Black women are three times more likely than white women to die from pregnancy-related complications. While deaths made up only a small portion of the bad outcomes for Black veterans cited in the report, VA care could not spare them from elevated rates of severe complications. Johnson said the maternal health crisis also persists within the VA.
“There is a disparity,” Johnson said. “We are not immune to that.”
Research shows pregnant people who have used the VA’s coverage have higher rates of trauma and mental conditions that can increase their risks of complications and bad outcomes.
This may be because many people who join the military enter it having already faced trauma, said Dr. Laura Miller, a psychiatrist and the medical director of reproductive mental health at the VA.
She said veterans with PTSD have higher rates of complications such as preeclampsia, a potentially fatal condition related to high blood pressure, gestational diabetes and postpartum depression. If untreated during pregnancy, depression also increases the likelihood of preterm birth and lingering problems for babies.
Hundrup said she hopes this proactive work will improve maternal health.
“We want these numbers trending in the other direction,” Hundrup said.
