Metabolic Health Roadmap – by Brenda Wollenberg

The term “roadmap” is often used in informative books, but in this case, Wollenberg (a nutritionist with decades of experience) really does deliver what can very reasonably be described as a roadmap:
She provides chapters in the form of legs of a journey [to better metabolic health], and those legs are broadly divided into an “information center” to deliver new information, a “rest stop” for reflection, “roadwork” to guide the reader through implementing the information we just learned, in a practical fashion, and finally “traveller assistance” to give additional support / resources, as well as any potential troubleshooting, etc.
The information and guidance within are all based on very good science; a lot is what you will have read already about blood sugar management (generally the lynchpin of metabolic health in general), but there’s also a lot about leveraging epigenetics for our benefit, rather than being sabotaged by such.
There’s a little guidance that falls outside of nutrition (sleep, exercise, etc), but for the most part, Wollenberg stays within her own field of expertise, nutrition.
The style is idiosyncratic; it’s very clear that her goal is providing the promised roadmap, and not living up to any editor’s wish or publisher’s hope of living up to industry standard norms of book formatting. However, this pays off, because her delivery is clear and helpful while remaining personable and yet still bringing just as much actual science, and this makes for a very pleasant and informative read.
Bottom line: if you’d like to improve your metabolic health, as well as get held-by-the-hand through your health-improvement journey by a charming guide, this is very much the book for you!

Daily Activity Levels & The Measurable Difference They Make To Brain Health
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.
Most studies into the difference that exercise makes to cognitive decline are retrospective, i.e. they look backwards in time, asking participants what their exercise habits were like in the past [so many] years, and tallying that against their cognitive health in the present.
Some studies are interventional, and those are most often 3, 6, or 12 months, depending on funding. In those cases, they make a hypothesis (e.g. this intervention will boost this measure of brain health) and then test it.
However, humans aren’t generally great at making short term decisions for long term gains. In other words: if it’s rainy out, or you’re a little pushed for time, you’re likely to take the car over walking regardless of what data point this adjusts in an overarching pattern that will affect your brain’s amyloid-β clean-up rates in 5–20 years time.
Nine days
The study we’re going to look at today was a 9-day observational study, using smartphone-based tracking with check-ins every 3½ hours, with participants reporting their physical activity as light, moderate, or intense (these terms were defined and exemplified, so that everyone involved was singing from the same songsheet in terms of what activities constitute what intensity).
The sample size was reasonable (n=204) and was generally heterogenous sample (i.e. varied in terms of sex, racial background, and fitness level) of New Yorkers aged 40–65.
So, the input variable was activity level, and the output variable was cognitive fitness.
As to how they measured the output, two brain games assessed:
- cognitive processing speed, and
- working memory (a proxy for executive function).
What they found:
- participants active within the last 3½ hours had faster processing speed, equivalent to being four years younger
- response times in the working memory (for: executive function) task reflected similar processing speed improvements, for participants active in the last 3½ hours
And, which is important to note,
❝This benefit was observed regardless of whether the activities they reported were higher intensity (e.g., running/jogging) or lower intensity (e.g., walking, chores).❞

Practical take-away:
Move more often! At least every couple of hours (when not sleeping)!
The benefits will benefit you in the now, as well as down the line.

General Tso’s Chickpeas
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.
A fiber-rich, heart-healthy take on a classic:
You will need
- 1 can chickpeas, drained
- ¾ cup vegetable stock; ideally you made this yourself from vegetable cuttings that you kept in the freezer for this purpose, but failing that, you should be able to get low-sodium stock cubes at your local supermarket.
- ¼ cup arrowroot starch (cornstarch will do at a pinch, but arrowroot is better and has no flavor of its own)
- 3 tbsp coconut oil
- 2 tbsp grated fresh ginger
- ¼ bulb garlic, minced
- 2 tbsp honey (or maple syrup if you prefer, and if you don’t like sweetness, reduce this to 1 tbsp or even omit entirely, though it won’t be quite so “General Tso” if you do, but it’s your meal!)
- 2 tbsp tomato paste
- 2 tsp hot sauce
- 1 tsp black pepper, coarse ground
- 3 green onions, sliced
Method
(we suggest you read everything at least once before doing anything)
1) Coat the chickpeas in the arrowroot starch by tossing them together in a bowl
2) Heat the coconut oil in a skillet on a medium-high heat, and when hot, add the chickpeas, stirring for 3 minutes
3) Add the remaining ingredients in the order we gave (except the vegetable stock, which goes in last), stirring for 5 more minutes, or until the sauce thickens
4) Serve with the carb of your choice; we recommend our Tasty Versatile Rice Recipe
Enjoy!

Willpower: A Muscle To Flex, Or Spoons To Conserve?

Willpower: A Muscle To Flex, Or Spoons To Conserve?
We have previously written about motivation; this one’s not about that.
Rather, it’s about willpower itself, and especially, the maintenance of such. Which prompts the question…
Is willpower something that can be built up through practice, or something that is a finite resource that can be expended?
That depends on you—and your experiences.
- Some people believe willpower is a metaphorical “muscle” that must be exercised to be built up
- Some people believe willpower is a matter of metaphorical “spoons” that can be used up
A quick note on spoon theory: this traces its roots to Christine Miserandino’s 2003 essay about chronic illness and the management of limited energy. She details how she explained this to a friend in a practical fashion, she gave her a bunch of spoons from her kitchen, as an arbitrary unit of energy currency. These spoons would then need to be used to “pay” for tasks done; soon her friend realised that if she wanted to make it through the day, she was going to have to give more forethought to how she would “spend” her spoons, or she’d run out and be helpless (and perhaps hungry and far from home) before the day’s end. So, the kind of forethought and planning that a lot of people with chronic illnesses have to give to every day’s activities.
You can read it here: But You Don’t Look Sick? The Spoon Theory
So, why do some people believe one way, and some believe the other? It comes down to our experiences of our own willpower being built or expended. Researchers (Dr. Vanda Siber et al.) studied this, and concluded:
❝The studies support the idea that what people believe about willpower depends, at least in part, on recent experiences with tasks as being energizing or draining.❞
Source: Autonomous Goal Striving Promotes a Nonlimited Theory About Willpower
In other words, there’s a difference between going out running each morning while healthy, and doing so with (for example) lupus.
On a practical level, this translates to practicable advice:
- If something requires willpower but is energizing, this is the muscle kind! Build it.
- If something requires willpower and is draining, this is the spoons kind! Conserve it.
Read the above two bullet-points as many times as necessary to cement them into your hippocampus, because they are the most important message of today’s newsletter.
Do you tend towards the “nonlimited” belief, despite getting tired? If so, here’s why…
There is something that can continue to empower us even when we get physically fatigued, and that’s the extent to which we truly get a choice about what we’re doing. In other words, that “Autonomous” at the front of the title of the previous study, isn’t just word salad.
- If we perceive ourselves as choosing to do what we are doing, with free will and autonomy (i.e., no externally created punitive consequences), we will feel much more empowered, and that goes for our willpower too.
- If we perceive ourselves as doing what we have to (or suffer the consequences), we’ll probably do it, but we’ll find it draining, and that goes for our willpower too.
Until such a time as age-related physical and mental decline truly take us, we as humans tend to gradually accumulate autonomy in our lives. We start as literal babies, then are children with all important decisions made for us, then adolescents building our own identity and ways of doing things, then young adults launching ourselves into the world of adulthood (with mixed results), to a usually more settled middle-age that still has a lot of external stressors and responsibilities, to old age, where we’ve often most things in order, and just ourselves and perhaps our partner to consider.
Consequently…
Age differences in implicit theories about willpower: why older people endorse a nonlimited theory
…which explains why the 30-year-old middle-manager might break down and burn out and stop going to work, while an octogenarian is busy training for a marathon daily before getting back to their daily book-writing session, without fail.
One final thing…
If you need a willpower boost, have a snack*. If you need to willpower boost to avoid snacking, then plan for this in advance by finding a way to keep your blood sugars stable. Because…

*Something that will keep your blood sugars stable, not spike them. Nuts are a great example, unless you’re allergic to such, because they have a nice balance of carbohydrates, protein, and healthy fats.

Gut Renovation – by Dr. Roshini Raj, with Sheila Buff
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.
Unless we actually feel something going on down there, gut health is an oft-neglected part of overall health—which is unfortunate, because invisible as it may often be, it affects so much.
Gastroenterologist Dr. Roshini Raj gives us all the need-to-know information, explanations of why things happen the way they do with regard to the gut, and tips, tricks, and hacks to improve matters.
She also does some mythbusting along the way, and advises about what things don’t make a huge difference, including what medications don’t have a lot of evidence for their usefulness.
The style is easy-reading pop-science, with plenty of high-quality medical content.
Reading between the lines, a lot of the book as it stands was probably written by the co-author, Sheila Buff, who is a professional ghostwriter and specializes in working closely with doctors to produce works that are readable and informative to the layperson while still being full of the doctor’s knowledge and expertise. So a reasonable scenario is that Dr. Raj gave her extensive notes, she took it from there, passed it back to her for medical corrections, and they had a little back and forth until it was done. Whatever their setup, the end result was definitely good!
Bottom line: if you’d like a guide to gut health that’s practical and easy to read, while being quite comprehensive and certainly a lot more than “eat probiotics and fiber”, then this book is a fine choice.

Kidney Beans vs Pinto Beans – Which is Healthier?
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.
Our Verdict
When comparing kidney beans to pinto beans, we picked the pinto.
Why?
Looking at the macros first, pinto beans have slightly more protein and carbs, and a lot more fiber, making them the all-round “more food per food” choice.
In the vitamins category, kidney beans have more of vitamins B3, C, and K, while pinto beans have more of vitamins B1, B2, B6, B9, E, and choline; another win for pinto beans. In kidney beans’ defense though, with the exception of vitamin E (31x more in pinto beans) the margins of difference are small for the rest of these vitamins, making kidney beans a close runner-up. Still, at least a nominal win for pinto beans here, by the numbers.
When it comes to minerals, kidney beans are not higher in any minerals, while pinto beans have more calcium, copper, magnesium, manganese, phosphorus, potassium, and selenium. In kidney beans’ defense, though, with the exception of selenium (5–6x more in pinto beans) the margins of difference are small for the rest of these minerals, making kidney beans a fine choice here too. Once again though, a winner is declarable here by the numbers, and it’s pinto beans.
Adding up the three wins makes for one big win for pinto beans. Still, enjoy either or both, because kidney beans are great too, and so is diversity!

Ricezempic: is there any evidence this TikTok trend will help you lose weight?
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.
If you spend any time looking at diet and lifestyle content on social media, you may well have encountered a variety of weight loss “hacks”.
One of the more recent trends is a home-made drink called ricezempic, made by soaking uncooked rice and then straining it to drink the leftover starchy water. Sounds delicious, right?
Its proponents claim it leads to weight loss by making you feel fuller for longer and suppressing your appetite, working in a similar way to the sought-after drug Ozempic – hence the name.
So does this drink actually mimic the weight loss effects of Ozempic? Spoiler alert – probably not. But let’s look at what the evidence tells us.
New Africa/Shutterstock How do you make ricezempic?
While the recipe can vary slightly depending on who you ask, the most common steps to make ricezempic are:
- soak half a cup of white rice (unrinsed) in one cup of warm or hot water up to overnight
- drain the rice mixture into a fresh glass using a strainer
- discard the rice (but keep the starchy water)
- add the juice of half a lime or lemon to the starchy water and drink.
TikTokers advise that best results will happen if you drink this concoction once a day, first thing in the morning, before eating.
The idea is that the longer you consume ricezempic for, the more weight you’ll lose. Some claim introducing the drink into your diet can lead to a weight loss of up to 27 kilograms in two months.
Resistant starch
Those touting ricezempic argue it leads to weight loss because of the resistant starch rice contains. Resistant starch is a type of dietary fibre (also classified as a prebiotic). There’s no strong evidence it makes you feel fuller for longer, but it does have proven health benefits.
Studies have shown consuming resistant starch may help regulate blood sugar, aid weight loss and improve gut health.
Research has also shown eating resistant starch reduces the risk of obesity, diabetes, heart disease and other chronic diseases.
Ricezempic is made by soaking rice in water. Kristi Blokhin/Shutterstock Resistant starch is found in many foods. These include beans, lentils, wholegrains (oats, barley, and rice – particularly brown rice), bananas (especially when they’re under-ripe or green), potatoes, and nuts and seeds (particularly chia seeds, flaxseeds and almonds).
Half a cup of uncooked white rice (as per the ricezempic recipe) contains around 0.6 grams of resistant starch. For optimal health benefits, a daily intake of 15–20 grams of resistant starch is recommended. Although there is no concrete evidence on the amount of resistant starch that leaches from rice into water, it’s likely to be significantly less than 0.6 grams as the whole rice grain is not being consumed.
Ricezempic vs Ozempic
Ozempic was originally developed to help people with diabetes manage their blood sugar levels but is now commonly used for weight loss.
Ozempic, along with similar medications such as Wegovy and Trulicity, is a glucagon-like peptide-1 (GLP-1) receptor agonist. These drugs mimic the GLP-1 hormone the body naturally produces. By doing so, they slow down the digestive process, which helps people feel fuller for longer, and curbs their appetite.
While the resistant starch in rice could induce some similar benefits to Ozempic (such as feeling full and therefore reducing energy intake), no scientific studies have trialled ricezempic using the recipes promoted on social media.
Ozempic has a long half-life, remaining active in the body for about seven days. In contrast, consuming one cup of rice provides a feeling of fullness for only a few hours. And simply soaking rice in water and drinking the starchy water will not provide the same level of satiety as eating the rice itself.
Other ways to get resistant starch in your diet
There are several ways to consume more resistant starch while also gaining additional nutrients and vitamins compared to what you get from ricezempic.
1. Cooked and cooled rice
Letting cooked rice cool over time increases its resistant starch content. Reheating the rice does not significantly reduce the amount of resistant starch that forms during cooling. Brown rice is preferable to white rice due to its higher fibre content and additional micronutrients such as phosphorus and magnesium.
2. More legumes
These are high in resistant starch and have been shown to promote weight management when eaten regularly. Why not try a recipe that has pinto beans, chickpeas, black beans or peas for dinner tonight?
3. Cooked and cooled potatoes
Cooking potatoes and allowing them to cool for at least a few hours increases their resistant starch content. Fully cooled potatoes are a rich source of resistant starch and also provide essential nutrients like potassium and vitamin C. Making a potato salad as a side dish is a great way to get these benefits.
In a nutshell
Although many people on social media have reported benefits, there’s no scientific evidence drinking rice water or “ricezempic” is effective for weight loss. You probably won’t see any significant changes in your weight by drinking ricezempic and making no other adjustments to your diet or lifestyle.
While the drink may provide a small amount of resistant starch residue from the rice, and some hydration from the water, consuming foods that contain resistant starch in their full form would offer significantly more nutritional benefits.
More broadly, be wary of the weight loss hacks you see on social media. Achieving lasting weight loss boils down to gradually adopting healthy eating habits and regular exercise, ensuring these changes become lifelong habits.
