What Are The “Bright Lines” Of Bright Line Eating?
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.

This is Dr. Susan Thompson. She’s a cognitive neuroscientist who has turned her hand to helping people to lose weight and maintain it at a lower level, using psychology to combat overeating. She is the founder of “Bright Line Eating”.
We’ll say up front: it’s not without some controversy, and we’ll address that as we go, but we do believe the ideas are worth examining, and then we can apply them or not as befits our personal lives.
What does she want us to know?
Bright Line Eating’s general goal
Dr. Thompson’s mission statement is to help people be “happy, thin, and free”.
You will note that this presupposes thinness as desirable, and presumes it to be healthy, which frankly, it’s not for everyone. Indeed, for people over a certain age, having a BMI that’s slightly into the “overweight” category is a protective factor against mortality (which is partly a flaw of the BMI system, but is an interesting observation nonetheless):
When BMI Doesn’t Quite Measure Up
Nevertheless, Dr. Thompson makes the case for the three items (happy, thin, free) coming together, which means that any miserable or unhealthy thinness is not what the approach is valuing, since it is important for “thin” to be bookended by “happy” and “free”.
What are these “bright lines”?
Bright Line Eating comes with 4 rules:
- No flour (no, not even wholegrain flour; enjoy whole grains themselves yes, but flour, no)
- No sugar (and as a tag-along to this, no alcohol) (sugars naturally found in whole foods, e.g. the sugar in an apple if eating an apple, is ok, but other kinds are not, e.g. foods with apple juice concentrate as a sweetener; no “natural raw cane sugar” etc is not allowed either; despite the name, it certainly doesn’t grow on the plant like that)
- No snacking, just three meals per day(not even eating the ingredients while cooking—which also means no taste-testing while cooking)
- Weigh all your food (have fun in restaurants—but more seriously, the idea here is to plan each day’s 3 meals to deliver a healthy macronutrient balance and a capped calorie total).
You may be thinking: “that sounds dismal, and not at all bright and cheerful, and certainly not happy and free”
The name comes from the idea that these rules are lines that one does not cross. They are “bright” lines because they should be observed with a bright and cheery demeanour, for they are the rules that, Dr. Thompson says, will make you “happy, thin, and free”.
You will note that this is completely in opposition to the expert opinion we hosted last week:
What Flexible Dieting Really Means
Dr. Thompson’s position on “freedom” is that Bright Line Eating is “very structured and takes a liberating stand against moderation”
Which may sound a bit of an oxymoron—is she really saying that we are going to be made free from freedom?
But there is some logic to it, and it’s about the freedom from having to make many food-related decisions at times when we’re likely to make bad ones:
Where does the psychology come in?
Dr. Thompson’s position is that willpower is a finite, expendable resource, and therefore we should use it judiciously.
So, much like Steve Jobs famously wore the same clothes every day because he had enough decisions to make later in the day that he didn’t want unnecessary extra decisions to make… Bright Line Eating proposes that we make certain clear decisions up front about our eating, so then we don’t have to make so many decisions (and potentially the wrong decisions) later when hungry.
You may be wondering: ”doesn’t sticking to what we decided still require willpower?”
And… Potentially. But the key here is shutting down self-negotiation.
Without clear lines drawn in advance, one must decide, “shall I have this cake or not?”, perhaps reflecting on the pros and cons, the context of the situation, the kind of day we’re having, how hungry we are, what else there is available to eat, what else we have eaten already, etc etc.
In short, there are lots of opportunities to rationalize the decision to eat the cake.
With clear lines drawn in advance, one must decide, “shall I have this cake or not?” and the answer is “no”.
So while sticking to that pre-decided “no” still may require some willpower, it no longer comes with a slew of tempting opportunities to rationalize a “yes”.
Which means a much greater success rate, both in adherence and outcomes. Here’s an 8-week interventional study and 2-year follow-up:
Bright Line Eating | Research Publications
Counterpoint: pick your own “bright lines”
Dr. Thompson is very keen on her 4 rules that have worked for her and many people, but she recognizes that they may not be a perfect fit for everyone.
So, it is possible to pick and choose our own “bright lines”; it is after all a dietary approach, not a religion. Here’s her response to someone who adopted the first 3 rules, but not the 4th:
Bright Lines as Guidelines for Weight Loss
The most important thing for Bright Line Eating, therefore, is perhaps the action of making clear decisions in advance and sticking to them, rather than seat-of-the-pantsing our diet, and with it, our health.

Peas vs Broad 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 peas to broad beans, we picked the peas.
Why?
Both are great of course, but…
Looking at the macros to start with, peas have more protein and more fiber. The differences aren’t huge, but they are clear.
In terms of vitamins, peas have more of vitamins A, B1, B2, B3, B5, B6, B9, E, K, and choline (some with very large margins, some with small), while broad beans contain a little more vitamin C (the margin is quite narrow though).
When it comes to minerals, peas have more calcium, copper, iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc, while broad beans have more sodium. So this category wasn’t close.
Adding up the win from each of the categories makes for a clear triple-win for peas.
Easy-peasy!

Military Secrets (Ssh!)
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.
Can you keep a secret?
When actor Christopher Lee was asked about his time as a British special forces operative, he would look furtively around, and ask “can you keep a secret?” Upon getting a yes, he would reply:
“So can I”
We can’t, though! We just can’t help sharing cool, useful information that changes people’s lives. Never is that more critical than now, as the end of January has been called the most depressing time of year, according to Dr. Cliff Arnall at the University of Cardiff. It doesn’t have to be all doom and gloom, though:
Today we’re going to share a trick… It’s called the “secret of eternal happiness” (yes, we know… we didn’t come up with the name!) and is taught to soldiers to fend off the worst kinds of despair.
The soldiers would be ordered to take a moment to reflect on the sheer helplessness of their situation, the ridiculous impossibility of the odds against them, all and any physical pain they might suffer, the weakness of their faltering body… and just when everything feels as bad is it can possibly feel, they’re told to say out loud—as sadly as possible—this single word:
“Boop”
It all but guarantees to result in cracking a smile, no matter the situation.
Now this knowledge is yours too! Keep it secret! Or don’t. Sharing is caring.

Improving Women’s Health Across the Lifespan – by Dr. Michelle Tollefson et al.
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.
We say “et al.”, because this hefty book (504 pages) is a compilation of contributions by about 60 authors, of whom, 100% are doctors and about 90% are women.
As one might expect from a book with many small self-contained chapters by such a lot of doctors, the content is very diverse, though the style is consistent throughout, likely due to the authors working from a style sheet, plus the work of the editorial team.
About that content: the focus here is lifestyle medicine, and while much of the advice will go for men too (most people are unlikely to go wrong with “eat more fruits and vegetables and get better sleep” etc), anything more detailed than that (of which there’s a lot) is focussed on women. Hence, we get chapters on optimal nutrition for women, physical activity for women, sleep and women’s health, etc, as well as topics that can affect everyone but disproportionately affect women—ranging from autoimmune diseases to social burdens that affect health in measurable ways. There’s also, as you might expect, plenty about sexual health, pregnancy-related health, menopausal health, and so forth.
The strength of this book is really in its diversity; it’s very much a case of “60 heads are better than one”, and as such, we’re pretty much getting 60 books for the price of one here, as each author brings what they are most specialized in.
Bottom line: if you are a woman and/or love a woman, this book is packed with information that will be of interest and applicable use.

Red Potatoes vs Russet Potatoes – 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 red potatoes to russet potatoes, we picked the russet.
Why?
In terms of macros, russet potatoes have more fiber, carbs, and protein; the ratio of fiber and carbs also gives them the lower glycemic index*, so really, a complete win for russets in the macros category.
*Glycemic index of potatoes change a lot depending on what you do to them, but this statement (about russets having the lower GI) continues to hold true on a like-for-like basis, i.e. assuming we continue to compare the potatoes having been cooked the same way as each other. They’re poisonous raw, so please don’t eat them that way. We right now are looking at stats for potatoes “flesh and skin, baked“, which is generally considered the healthiest way to eat potatoes. Obviously, if you make them into mash then the glycemic index will be sky-high, and if you make them into fries they’ll now have lots of fat added, etc. So let’s just stick to the baked potatoes for now.
In the category of vitamins, red potatoes have more vitamin C, while russet potatoes have more vitamin B6. All the other minerals are close enough between both potatoes to be within reasonable margins of variation/error (in particular, they are both fair sources of vitamins B1, B2, B3, B5, and B9), so it’s really just between those two vitamins, so we’ll call this round a tie.
When it comes to minerals, red potatoes have more copper, phosphorus, and zinc, while russet potatoes have more calcium, iron, magnesium, manganese, and potassium. Thus, a win for russets here.
Adding up the sections gives an overall win for russets, but by all means, enjoy either or both; diversity is good!

What Flexible Dieting Really Means
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.
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”.
On enjoying food fully, by the way:

Thai-Style Kale Chips
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.
…that are actually crispy, tasty, and packed with nutrients! Lots of magnesium and calcium, and array of health-giving spices too.
You will need
- 7 oz raw curly kale, stalks removed
- extra virgin olive oil, for drizzling
- 3 cloves garlic, crushed
- 2 tsp red chili flakes (or crushed dried red chilis)
- 2 tsp light soy sauce
- 2 tsp water
- 1 tbsp crunchy peanut butter (pick one with no added sugar, salt, etc)
- 1 tsp honey
- 1 tsp Thai seven-spice powder
- 1 tsp black pepper
- 1 tsp MSG or 1 tsp low-sodium salt
Method
(we suggest you read everything at least once before doing anything)
1) Pre-heat the oven to 180℃ / 350℉ / Gas mark 4.
2) Put the kale in a bowl and drizzle a little olive oil over it. Work the oil in gently with your fingertips so that the kale is coated; the leaves will also soften while you do this; that’s expected, so don’t worry.
3) Mix the rest of the ingredients to make a sauce; coat the kale leaves with the sauce.
4) Place on a baking tray, as spread-out as there’s room for, and bake on a middle shelf for 15–20 minutes. If your oven has a fierce heat source at the top, it can be good to place an empty baking tray on a shelf above the kale chips, to baffle the heat and prevent them from cooking unevenly—especially if it’s not a fan oven.
5) Remove and let cool, and then serve! They can also be stored in an airtight container if desired.
Enjoy!
