“You Just Need to Lose Weight” And 19 Other Myths About Fat People – by Aubrey Gordon

We’ve previously reviewed another book by this author, “What We Don’t Talk About When We Talk About Fat”, and this time, she’s doing some important mythbusting.
The titular “you just need to lose weight” is a commonly-taken easy-out for many doctors, to avoid having to dispense actual treatment for an actual condition. Whether or not weight loss would help in a given situation is often immaterial; “kicking the can down the road” is the goal.
Most of the book is divided into 20 chapters, each of them devoted to debunking one myth. Think of it like 10almonds’ “Mythbusting Friday” edition (indeed, we did one about obesity), but with an entire book, and as much room as she needs to provide much more detail than we can ever get into in a single article.
And far from being a mere polemic, she does indeed provide that detail—this is clearly a very well-researched book, above and beyond the author’s own personal experience. Further, all the key points are illustrated and articulated clearly, making the book’s ideas very comprehensible.
The style is pop-science, but with frequent bibliographical references for relevant sources.
Bottom line: for some readers, this book will come as a great validation; for others, it may be eye-opening. Either way, it’s a very worthwhile read.

I’ve been sick. When can I start exercising again?

You’ve had a cold or the flu and your symptoms have begun to subside. Your nose has stopped dripping, your cough is clearing and your head and muscles no longer ache.
You’re ready to get off the couch. But is it too early to go for a run? Here’s what to consider when getting back to exercising after illness.
Ketut Subiyanto/Pexels Exercise can boost your immune system – but not always
Exercise reduces the chance of getting respiratory infections by increasing your immune function and the ability to fight off viruses.
However, an acute bout of endurance exercise may temporarily increase your susceptibility to upper respiratory infections, such as colds and the flu, via the short-term suppression of your immune system. This is known as the “open window” theory.
A study from 2010 examined changes in trained cyclists’ immune systems up to eight hours after two-hour high-intensity cycling. It found important immune functions were suppressed, resulting in an increased rate of upper respiratory infections after the intense endurance exercise.
So, we have to be more careful after performing harder exercises than normal.
Can you exercise when you’re sick?
This depends on the severity of your symptoms and the intensity of exercise.
Mild to moderate exercise (reducing the intensity and length of workout) may be OK if your symptoms are a runny nose, nasal congestion, sneezing and minor sore throat, without a fever.
Exercise may help you feel better by opening your nasal passages and temporarily relieving nasal congestion.
If you have a runny or blocked nose and no fever, low-intensity movement such as a walk might help. Laker/Pexels However, if you try to exercise at your normal intensity when you are sick, you risk injury or more serious illness. So it’s important to listen to your body.
If your symptoms include chest congestion, a cough, upset stomach, fever, fatigue or widespread muscle aches, avoid exercising. Exercising when you have these symptoms may worsen the symptoms and prolong the recovery time.
If you’ve had the flu or another respiratory illness that caused a high fever, make sure your temperature is back to normal before getting back to exercise. Exercising raises your body temperature, so if you already have a fever, your temperature will become high quicker, which makes you sicker.
If you have COVID or other contagious illnesses, stay at home, rest and isolate yourself from others.
When you’re sick and feel weak, don’t force yourself to exercise. Focus instead on getting plenty of rest. This may actually shorten the time it takes to recover and resume your normal workout routine.
I’ve been sick for a few weeks. What has happened to my strength and fitness?
You may think taking two weeks off from training is disastrous, and worry you’ll lose the gains you’ve made in your previous workouts. But it could be just what the body needs.
It’s true that almost all training benefits are reversible to some degree. This means the physical fitness that you have built up over time can be lost without regular exercise.
To study the effects of de-training on our body functions, researchers have undertaken “bed rest” studies, where healthy volunteers spend up to 70 days in bed. They found that V̇O₂max (the maximum amount of oxygen a person can use during maximal exercise, which is a measure of aerobic fitness) declines 0.3–0.4% a day. And the higher pre-bed-rest V̇O₂max levels, the larger the declines.
In terms of skeletal muscles, upper thigh muscles become smaller by 2% after five days of bed rest, 5% at 14 days, and 12% at 35 days of bed rest.
Muscle strength declines more than muscle mass: knee extensor muscle strength gets weaker by 8% at five days, 12% at 14 days and more than 20% after around 35 days of bed rest.
This is why it feels harder to do the same exercises after resting for even five days.
In bed rest studies, participants don’t get up. But they do in real life. Olly/Pexels But in bed rest studies, physical activities are strictly limited, and even standing up from a bed is prohibited during the whole length of a study. When we’re sick in bed, we have some physical activities such as sitting on a bed, standing up and walking to the toilet. These activities could reduce the rate of decreases in our physical functions compared with study participants.
How to ease back into exercise
Start with a lower-intensity workout initially, such as going for a walk instead of a run. Your first workout back should be light so you don’t get out of breath. Go low (intensity) and go slow.
Gradually increase the volume and intensity to the previous level. It may take the same number of days or weeks you rested to get back to where you were. If you were absent from an exercise routine for two weeks, for example, it may require two weeks for your fitness to return to the same level.
If you feel exhausted after exercising, take an extra day off before working out again. A day or two off from exercising shouldn’t affect your performance very much.

CLA for Weight Loss?
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.
Conjugated Linoleic Acid for Weight Loss?
You asked us to evaluate the use of CLA for weight loss, so that’s today’s main feature!
First, what is CLA?
Conjugated Linoleic Acid (CLA) is a fatty acid made by grazing animals. Humans don’t make it ourselves, and it’s not an essential nutrient.
Nevertheless, it’s a popular supplement, mostly sold as a fat-burning helper, and thus enjoyed by slimmers and bodybuilders alike.
❝CLA reduces bodyfat❞—True or False?
True! Contingently. Specifically, it will definitely clearly help in some cases. For example:
- This study found it doubled fat loss in chickens
- It significantly increased delipidation of white adipose tissue in these mice
- The mice in this study enjoyed a 43–88% reduction in (fatty) weight gain
- Over the course of a six-week weight-loss program, these mice got 70% more weight loss on CLA, compared to placebo
- In this study, pigs that took CLA on a high-calorie diet gained 50% less weight than those not taking CLA
- On a heart-unhealthy diet, these hamsters taking CLA gained much less white adipose tissue than their comrades not taking CLA
- Another study with pigs found that again, CLA supplementation resulted in much less weight gained
- These hamsters being fed a high-cholesterol diet found that those taking CLA ended up with a leaner body mass than those not taking CLA
- This study with mice found that CLA supplementation promoted fat loss and lean muscle gain
Did you notice a theme? It’s Animal Farm out there!
❝CLA reduces bodyfat in humans❞—True or False?
False—practically. Technically it appears to give non-significantly better results than placebo.
A comprehensive meta-analysis of 18 different studies (in which CLA was provided to humans in randomized, double-blinded, placebo-controlled trials and in which body composition was assessed by using a validated technique) found that, on average, human CLA-takers lost…
Drumroll please…
00.00–00.05 kg per week. That’s between 0–50g per week. That’s less than two ounces. Put it this way: if you were to quickly drink an espresso before stepping on the scale, the weight of your very tiny coffee would cover your fat loss.
The reviewers concluded:
❝CLA produces a modest loss in body fat in humans❞
Modest indeed!
See for yourself: Efficacy of conjugated linoleic acid for reducing fat mass: a meta-analysis in humans
But what about long-term? Well, as it happens (and as did show up in the non-human animal studies too, by the way) CLA works best for the first four weeks or so, and then effects taper off.
Another review of longer-term randomized clinical trials (in humans) found that over the course of a year, CLA-takers enjoyed on average a 1.33kg total weight loss benefit over placebo—so that’s the equivalent of about 25g (0.8 oz) per week. We’re talking less than a shot glass now.
They concluded:
❝The evidence from RCTs does not convincingly show that CLA intake generates any clinically relevant effects on body composition on the long term❞
A couple of other studies we’ll quickly mention before closing this section:
- CLA supplementation does not affect waist circumference in humans (at all).
- Amongst obese women doing aerobic exercise, CLA supplementation has no effect (at all) on body fat reduction compared to placebo
What does work?
You may remember this headline from our “What’s happening in the health world” section a few days ago:
Research reveals self-monitoring behaviors and tracking tools key to long-term weight loss success
On which note, we’ve mentioned before, we’ll mention again, and maybe one of these days we’ll do a main feature on it, there’s a psychology-based app/service “Noom” that’s very personalizable and helps you reach your own health goals, whatever they might be, in a manner consistent with any lifestyle considerations you might want to give it.

Taurine: An Anti-Aging Powerhouse? Exploring Its Unexpected Benefits
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.
Dr. Mark Rosenberg explains:
Not a stimulant, but…
- Its presence in energy drinks often causes people to assume it’s a stimulant, but it’s not. In fact, it’s a GABA-agonist, thus having a calming effect.
- The real reason it’s in energy drinks is because it helps increase mitochondrial ATP production (ATP = adenosine triphosphate = how cells store energy that’s ready to use; mitochondria take glucose and make ATP)
- Taurine is also anti-inflammatory, antioxidant, and anticancer.
- In the category of aging, human studies are slow to give results for obvious reasons, but mouse studies show that supplementing taurine in middle-aged mice increased their lifespan by 10–12%, as well as improving various physiological markers of aging.
- Taking a closer look at aging—literally; looking at cellular aging—taurine reduces cellular senescence and protects telomeres, thus decreasing DNA mutations.

Broccoli vs Cauliflower – 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 broccoli to cauliflower, we picked the broccoli.
Why?
This one is quite straightforward. Superficially, they’re very similar:
Both are great cruciferous vegetables with many health benefits to offer. Even for those keen to avoid oxalates, which cruciferous vegetables in general can be high in, these ones are quite low.
However, if you have IBS, you might want to avoid both, for their raffinose content that may cause problems for you.
For pretty much everyone else, unless you have a special reason why it’s not the case for you, both are a good source of abundant vitamins and minerals, and yet…
Anything cauliflower can do, broccoli can do better!
Broccoli contains more of the vitamins they both contain, and more of the minerals they both contain.
Broccoli also beats cauliflower on amino acids (except lysine), and contains a lot more lutein and zeaxanthin, carotenoids important for healthy eyes and brain.
So by all means enjoy both, but if you’re going to pick one, pick broccoli!

Semaglutide for Weight Loss?
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.
Semaglutide for weight loss?
Semaglutide is the new kid on the weight-loss block, but it’s looking promising (with some caveats!).
Most popularly by brand names Ozempic and Wegovy, it was first trialled to help diabetics*, and is now sought-after by the rest of the population too. So far, only Wegovy is FDA-approved for weight loss. It contains more semaglutide than Ozempic, and was developed specifically for weight loss, rather than for diabetes.
*Specifically: diabetics with type 2 diabetes. Because it works by helping the pancreas to make insulin, it’s of no help whatsoever to T1D folks, sadly. If you’re T1D and reading this though, today’s book of the day is for you!
First things first: does it work as marketed for diabetes?
It does! At a cost: a very common side effect is gastrointestinal problems—same as for tirzepatide, which (like semaglutide) is a GLP-1 agonist, meaning it works the same way. Here’s how they measure up:
- Head-to-head study: Effects of subcutaneous tirzepatide versus placebo or semaglutide on pancreatic islet function and insulin sensitivity in adults with type 2 diabetes
- Head-to-head systematic review: Semaglutide for the treatment of type 2 Diabetes Mellitus: A systematic review and network meta-analysis of safety and efficacy outcomes
As you can see, both of them work wonders for pancreatic function and insulin sensitivity!
And, both of them were quite unpleasant for around 20% of participants:
❝Tirzepatide, oral and SC semaglutide has a favourable efficacy in treating T2DM. Gastrointestinal adverse events were highly recorded in tirzepatide, oral and SC semaglutide groups.❞
What about for weight loss, if not diabetic?
It works just the same! With just the same likelihood of gastro-intestinal unpleasantries, though. There’s a very good study that was done with 1,961 overweight adults; here it is:
Once-Weekly Semaglutide in Adults with Overweight or Obesity
The most interesting things here are the positive results and the side effects:
❝The mean change in body weight from baseline to week 68 was −14.9% in the semaglutide group as compared with −2.4% with placebo, for an estimated treatment difference of −12.4 percentage points (95% confidence interval [CI], −13.4 to −11.5; P<0.001).❞
In other words: if you take this, you’re almost certainly going to get something like 6x better weight loss results than doing the same thing without it.
❝Nausea and diarrhea were the most common adverse events with semaglutide; they were typically transient and mild-to-moderate in severity and subsided with time. More participants in the semaglutide group than in the placebo group discontinued treatment owing to gastrointestinal events (59 [4.5%] vs. 5 [0.8%])❞
~ ibid.
In other words: you have about a 3% chance of having unpleasant enough side effects that you don’t want to continue treatment (contrast this with the 20%ish chance of unpleasant side effects of any extent)!
Any other downsides we should know about?
If you stop taking it, weight regain is likely. For example, a participant in one of the above-mentioned studies who lost 22% of her body weight with the drug’s help, says:
❝Now that I am no longer taking the drug, unfortunately, my weight is returning to what it used to be. It felt effortless losing weight while on the trial, but now it has gone back to feeling like a constant battle with food. I hope that, if the drug can be approved for people like me, my [doctor] will be able to prescribe the drug for me in the future.❞
~ Jan, a trial participant at UCLH
Is it injection-only, or is there an oral option?
An oral option exists, but (so far) is on the market only in the form of Rybelsus, another (slightly older) drug containing semaglutide, and it’s (so far) only FDA-approved for diabetes, not for weight loss. See:
A new era for oral peptides: SNAC and the development of oral semaglutide for the treatment of type 2 diabetes ← for the science
FDA approves first oral GLP-1 treatment for type 2 diabetes ← For the FDA statement
Where can I get these?

Yes, blue light from your phone can harm your skin. A dermatologist explains
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.
Social media is full of claims that everyday habits can harm your skin. It’s also full of recommendations or advertisements for products that can protect you.
Now social media has blue light from our devices in its sights.
So can scrolling on our phones really damage your skin? And will applying creams or lotions help?
Here’s what the evidence says and what we should really be focusing on.
Max kegfire/Shutterstock Remind me, what actually is blue light?
Blue light is part of the visible light spectrum. Sunlight is the strongest source. But our electronic devices – such as our phones, laptops and TVs – also emit it, albeit at levels 100-1,000 times lower.
Seeing as we spend so much time using these devices, there has been some concern about the impact of blue light on our health, including on our eyes and sleep.
Now, we’re learning more about the impact of blue light on our skin.
How does blue light affect the skin?
The evidence for blue light’s impact on skin is still emerging. But there are some interesting findings.
1. Blue light can increase pigmentation
Studies suggest exposure to blue light can stimulate production of melanin, the natural skin pigment that gives skin its colour.
So too much blue light can potentially worsen hyperpigmentation – overproduction of melanin leading to dark spots on the skin – especially in people with darker skin.
Blue light can worsen dark spots on the skin caused by overproduction of melanin. DUANGJAN J/Shutterstock 2. Blue light can give you wrinkles
Some research suggests blue light might damage collagen, a protein essential for skin structure, potentially accelerating the formation of wrinkles.
A laboratory study suggests this can happen if you hold your device one centimetre from your skin for as little as an hour.
However, for most people, if you hold your device more than 10cm away from your skin, that would reduce your exposure 100-fold. So this is much less likely to be significant.
3. Blue light can disrupt your sleep, affecting your skin
If the skin around your eyes looks dull or puffy, it’s easy to blame this directly on blue light. But as we know blue light affects sleep, what you’re probably seeing are some of the visible signs of sleep deprivation.
We know blue light is particularly good at suppressing production of melatonin. This natural hormone normally signals to our bodies when it’s time for sleep and helps regulate our sleep-wake cycle.
By suppressing melatonin, blue light exposure before bed disrupts this natural process, making it harder to fall asleep and potentially reducing the quality of your sleep.
The stimulating nature of screen content further disrupts sleep. Social media feeds, news articles, video games, or even work emails can keep our brains active and alert, hindering the transition into a sleep state.
Long-term sleep problems can also worsen existing skin conditions, such as acne, eczema and rosacea.
Sleep deprivation can elevate cortisol levels, a stress hormone that breaks down collagen, the protein responsible for skin’s firmness. Lack of sleep can also weaken the skin’s natural barrier, making it more susceptible to environmental damage and dryness.
Can skincare protect me?
The beauty industry has capitalised on concerns about blue light and offers a range of protective products such as mists, serums and lip glosses.
From a practical perspective, probably only those with the more troublesome hyperpigmentation known as melasma need to be concerned about blue light from devices.
This condition requires the skin to be well protected from all visible light at all times. The only products that are totally effective are those that block all light, namely mineral-based suncreens or some cosmetics. If you can’t see the skin through them they are going to be effective.
But there is a lack of rigorous testing for non-opaque products outside laboratories. This makes it difficult to assess if they work and if it’s worth adding them to your skincare routine.
What can I do to minimise blue light then?
Here are some simple steps you can take to minimise your exposure to blue light, especially at night when it can disrupt your sleep:
- use the “night mode” setting on your device or use a blue-light filter app to reduce your exposure to blue light in the evening
- minimise screen time before bed and create a relaxing bedtime routine to avoid the types of sleep disturbances that can affect the health of your skin
- hold your phone or device away from your skin to minimise exposure to blue light
- use sunscreen. Mineral and physical sunscreens containing titanium dioxide and iron oxides offer broad protection, including from blue light.
In a nutshell
Blue light exposure has been linked with some skin concerns, particularly pigmentation for people with darker skin. However, research is ongoing.
While skincare to protect against blue light shows promise, more testing is needed to determine if it works.
For now, prioritise good sun protection with a broad-spectrum sunscreen, which not only protects against UV, but also light.
