Are Waist Trainers Just A Waste, And Are Posture Fixers A Quick Fix?
Yesterday, we asked you for your opinions on waist trainers and posture-fixing harnesses, and got the above-depicted, below-described set of results:
- The most popular response was “Waist trainers are purely cosmetic, so useless. Posture-fixers have merit”, with a little over a quarter of the votes.
- The least popular response was “Both are great tools to help us to optimal waist size and posture, respectively!”
- The other three answers each got a little under a quarter of the vote. In terms of discrete data, these were all 7±1, so basically, there was nothing in it.
The sample size was smaller than usual—perhaps the cluster of American holiday dates yesterday and today kept people busy! But, pressing on…
What does the science say?
Waist trainers are purely cosmetic, so, useless. True or False?
True, simply. Honestly, they’re not even that great for cosmetic purposes. They will indeed cinch in your middle, and this shape will be retained for a (very) short while after uncinching, because your organs have been squished inwards and may take a short while to get back to where they are supposed to be.
The American Board of Cosmetic Surgery may not be an unbiased source, but we’re struggling to find scientists who will even touch one of these, so, let’s see what these doctors have to say:
- Waist training can damage vital organs
- You will be slowly suffocating yourself
- Waist training simply doesn’t work
- You cannot drastically change your body shape with a piece of fabric*

*”But what about foot-binding?”—feet have many bones, whose growth can be physically restricted. Your waist has:
- organs: necessary! (long-term damage possible, but they’re not going away)
- muscles: slightly restrictable! (temporary restriction; no permanent change)
- fat: very squeezable! (temporary muffin; no permanent change)
Posture correctors have merit: True or False?
True—probably, and as a stepping-stone measure only.
The Ergonomics Health Association (a workplace health & safety organization) says:
❝Looking at the clinical evidence of posture correctors, we can say without a doubt that they do work, just not for everyone and not in the same way for all patients.❞
Source: Do Posture Correctors Work? Here’s What Our Experts Think
That’s not very compelling, so we looked for studies, and found… Not much, actually. However, what we did find supported the idea that “they probably do help, but we seriously need better studies with less bias”:
That is also not a compelling title, but here is where it pays to look at the studies and not just the titles. Basically, they found that the results were favorable to the posture-correctors—the science itself was just trash:
❝ The overall findings were that posture-correcting shirts change posture and subjectively have a positive effect on discomfort, energy levels and productivity.
The quality of the included literature was poor to fair with only one study being of good quality. The risk of bias was serious or critical for the included studies. Overall, this resulted in very low confidence in available evidence.❞
Since the benefit of posture correctors like this one is due to reminding the wearer to keep good posture, there is a lot more (good quality!) science for wearable biofeedback tech devices, such as this one:

Overcoming Gravity – by Steven Low
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.
The author, a professional gymnast and coach with a background in the sciences, knows his stuff here. This is what it says on the tin: it’s rigorously systematic. It’s also the most science-based calisthenics book this reviewer has read to date.
If you just wanted to know how to do some exercises, then this book would be very much overkill, but if you want to be able to go from no knowledge to expert knowledge, then the nearly 600 pages of this weighty tome will do that for you.
This is a textbook, it’s a “the bible of…” style book, it’s the one that if you’re serious, will engage you thoroughly and enable you to craft the calisthenics-forged body you want, head to toe.
As if it weren’t already overdelivering, it also has plenty of information on injury avoidance (or injury/condition management if you have some existing injury or chronic condition), and building routines in a dynamic fashion that avoids becoming a grind, because it’s going from strength to strength while cycling through different body parts.
Bottom line: if you’d like to get serious about calisthenics, then this is the book for you.

Peaceful Kitchen – by Catherine Perez
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.
The author, a keen cook and Registered Dietician with a Master’s in same, covers the basics of the science of nutrition as relevant to her recipes, but first and foremost this is not a science textbook—it’s a cookbook, and its pages contain more love for the art than citations for the (perfectly respectable) science.
Mexican and Dominican cuisine are the main influences in this book, but there are dishes from around the world too.
The recipes themselves are… Comparable in difficulty to the things we often feature in our recipes section here at 10almonds. They’re probably not winning any restaurants Michelin stars, but they’re not exactly student survival recipes either. They’re made from mostly non-obscure whole foods, nutritionally-dense ingredients at that, with minimal processed foods involved.
That said, she does take a “add, don’t subtract” approach to nutrition, i.e. focussing more on adding in diversity of plants than on “don’t eat this; don’t eat that” mandates.
If there’s any criticism to be levelled at the book, it’s that in most cases we’d multiply the spices severalfold, but that’s not a big problem as readers can always judge that individually; she’s given the basic information of which spices in which proportions, which is the key knowledge.
Bottom line: if you’re looking to expand your plant-based cooking repertoire, this one is a fine choice.

Is It Possible To Lose Weight Quickly?
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 Victorian England, weight-loss trends like the dangerous tapeworm diet were popular. While modern fad diets can seem less extreme, they often promise similarly fast results. However, these quick fixes can have similarly harmful consequences:
Not so fast
To illustrate the difference between gradual and extreme dieting, the video bids us consider two identical twins, Sam and Felix:
- Sam adopts a gradual approach, slowly reducing calorie intake and exercising regularly. This causes his body to burn glycogen stores before transitioning to fat as an energy source. Regular exercise helps Sam maintain muscle mass, which boosts his metabolism and supports sustained weight loss.
- Felix drastically cuts calories, forcing his body into starvation mode. He quickly depletes glycogen stores, loses muscle mass, and burns fewer calories, making long-term weight loss more difficult. Although Felix might initially lose water weight, this is temporary and unsustainable.
You cannot “just lose it quickly now, and then worry about healthiness once the weight’s gone”, because you will lose health much more quickly than you will lose fat, and that will sabotage, rather than help, your fat loss journey.Healthy weight loss requires gradual, balanced changes in diet and exercise tailored to individual needs. Extreme diets, whether through calorie restriction or things like elimination of carbs or fats, are unsustainable and shock the body. It’s important to prioritize long-term health over societal pressures for quick weight loss and focus on developing a sustainable, healthy lifestyle.
In short, the quickest way to lose weight and keep it off (without dying), is to lose it slowly.

Do Try This At Home: The 12-Week Brain Fitness Program
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.
12 Weeks To Measurably Boost Your Brain
This is Dr. Majid Fotuhi. From humble beginnings (being smuggled out of Iran in 1980 to avoid death in the war), he went on (after teaching himself English, French, and German, hedging his bets as he didn’t know for sure where life would lead him) to get his MD from Harvard Medical School and his PhD in neuroscience from Johns Hopkins University. Since then, he’s had a decades-long illustrious career in neurology and neurophysiology.
What does he want us to know?
The Brain Fitness Program
This is not, by the way, something he’s selling. Rather, it was a landmark 12-week study in which 127 people aged 60–80, of which 63% female, all with a diagnosis of mild cognitive impairment, underwent an interventional trial—in other words, a 12-week brain fitness course.
After it, 84% of the participants showed statistically significant improvements in cognitive function.
Not only that, but of those who underwent MRI testing before and after (not possible for everyone due to practical limitations), 71% showed either no further deterioration of the hippocampus, or actual growth above the baseline volume of the hippocampus (that’s good, and it means functionally the memory center of the brain has been rejuvenated).
You can read a little more about the study here:
As for what the program consisted of, and what Dr. Fotuhi thus recommends for everyone…
Cognitive stimulation
This is critical, so we’re going to spend most time on this one—the others we can give just a quick note and a pointer.
In the study this came in several forms and had the benefit of neurofeedback technology, but he says we can replicate most of the effects by simply doing something cognitively stimulating. Whatever challenges your brain is good, but for maximum effect, it should involve the language faculties of the brain, since these are what tend to get hit most by age-related cognitive decline, and are also what tends to have the biggest impact on life when lost.
If you lose your keys, that’s an inconvenience, but if you can’t communicate what is distressing you, or understand what someone is explaining to you, that’s many times worse—and that kind of thing is a common reality for many people with dementia.
To keep the lights brightly lit in that part of the brain: language-learning is good, at whatever level suits you personally. In other words: there’s a difference between entry-level Duolingo Spanish, and critically analysing Rumi’s poetry in the original Persian, so go with whatever is challenging and/but accessible for you—just like you wouldn’t go to the gym for the first time and try to deadlift 500lbs, but you also probably wouldn’t do curls with the same 1lb weights every day for 10 years.
In other words: progressive overloading is key, for the brain as well as for muscles. Start easy, but if you’re breezing through everything, it’s time to step it up.
If for some reason you’re really set against the idea of learning another language, though, check out:

Mediterranean diet
Shocking nobody, this is once again recommended. You might like to check out the brain-healthy “MIND” tweak to it, here:
Four Ways To Upgrade The Mediterranean Diet ← it’s the fourth one
Omega-3 supplementation
Nothing complicated here. The brain needs a healthy balance of these fatty acids to function properly, and most people have an incorrect balance (too little omega-3 for the omega-6 present):
What Omega-3 Fatty Acids Really Do For Us ← scroll to “against cognitive decline”
Increasing fitness
There’s a good rule of thumb: what’s healthy for your heart, is healthy for your brain. This is because, like every other organ in your body, the brain does not function well without good circulation bringing plenty of oxygen and nutrients, which means good cardiovascular health is necessary. The brain is extra sensitive to this because it’s a demanding organ in terms of how much stuff it needs delivering via blood, and also because of the (necessary; we’d die quickly and horribly without it) impediment of the blood-brain barrier, and the possibility of beta-amyloid plaques and similar woes (they will build up if circulation isn’t good).

Practising mindfulness medication
This is also straightforward, but not to be underestimated or skipped over:

Lastly…
Dr. Fotuhi wants us to consider looking after our brain the same way we look after our teeth. No, he doesn’t want us to brush our brain, but he does want us to take small measurable actions multiple times per day, every day.
You can’t just spend the day doing nothing but brushing your teeth for the entirety of January the 1st and then expect them to be healthy for the rest of the year; it doesn’t work like that—and it doesn’t work like that for the brain, either.
So, make the habits, and keep them going
Take care!

Eat to Beat Disease – by Dr. William Li
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. William Li asks the important question: is your diet feeding disease, or defeating it?
Because everything we put in our bodies makes our health just a little better—or just a little worse. Ok, sometimes a lot worse.
But for most people, when it comes to diet, it’s a death of a thousand cuts of unhealthy food. And that’s what he looks to fix with this book.
The good news: Dr. Li (while not advocating for unhealthy eating, of course), focuses less on what to restrict, and more on what to include. This book covers hundreds of such healthy foods, and ideas (practical, useful ones!) on incorporating them daily, including dozens of recipes.
He mainly looks at five ways our food can help us with…
- Angiogenesis (blood vessel replacement)
- Regeneration (of various bodily organs and systems)
- Microbiome health (and all of its knock-on effects)
- DNA protection (and thus slower cellular aging)
- Immunity (defending the body while also reducing autoimmune problems)
The style is simple and explanatory; Dr. Li is a great educator. Reading this isn’t a difficult read, but you’ll come out of it feeling like you just did a short course in health science.
Bottom line: if you’d like an easy way to improve your health in an ongoing and sustainable way, then this book can help you do just that.

Superfood Pesto Pizza
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 only is this pizza full of foods that punch above their weight healthwise, there’s no kneading and no waiting when it comes to the base, either. Homemade pizzas made easy!
You will need
For the topping:
- 1 zucchini, sliced
- 1 red bell pepper, cut into strips
- 3 oz mushrooms, sliced
- 3 shallots, cut into quarters
- 6 sun-dried tomatoes, roughly chopped
- ½ bulb garlic (paperwork done, but cloves left intact, unless they are very large, in which case halve them)
- 1 oz pitted black olives, halved
- 1 handful arugula
- 1 tbsp extra virgin olive oil
- 2 tsp black pepper, coarse ground
- ½ tsp MSG or 1 tsp low-sodium salt
For the base:
- ½ cup chickpea flour (also called besan or gram flour)
- 2 tsp extra virgin olive oil
- ½ tsp baking powder
- ⅛ tsp MSG or ¼ tsp low-sodium salt
For the pesto sauce:
- 1 large bunch basil, chopped
- ½ avocado, pitted and peeled
- 1 oz pine nuts
- ¼ bulb garlic, crushed
- 2 tbsp nutritional yeast
- 1 tsp black pepper
- Juice of ½ lemon
Method
(we suggest you read everything at least once before doing anything)
1) Preheat the oven to 400℉ / 200℃.
2) Toss the zucchini, bell pepper, mushrooms, shallots, and garlic cloves in 1 tbsp olive oil, ensuring an even coating. Season with the black pepper and MSG/salt, and put on a baking tray lined with baking paper, to roast for about 20 minutes, until they are slightly charred.
3) When the vegetables are in the oven, make the pizza base by combining the dry ingredients in a bowl, making a pit in the middle of it, adding the olive oil and whisking it in, and then slowly (i.e., a little bit at a time) whisking in 1 cup cold water. This should take under 5 minutes.
4) Don’t panic when this doesn’t become a dough; it is supposed to be a thick batter, so that’s fine. Pour it into a 9″ pizza pan, and bake for about 15 minutes, until firm. Rotate it if necessary partway through; whether it needs this or not will depend on your oven.
5) While the pizza base is in the oven, make the pesto sauce by blending all the pesto sauce ingredients in a high-speed blender until smooth.
6) When the base and vegetables are ready (these should be finished around the same time), spread the pesto sauce on the base, scatter the arugula over it followed by the vegetables and then the olives and sun-dried tomatoes.
7) Serve, adding any garnish or other final touches that take your fancy.
Enjoy!
