Anyone who has spent any time trying to get into shape (losing weight, lifting weights, doing cardio) knows that you will be bombarded by conflicting and downright dangerous information. Few industries are as loaded with misguided information and scammers than the fitness industry.
That said, I feel bad for anyone that struggles to lose weight and has to deal with all of the information and is trying to figure it all out. My recommendation is, calorie counting IS important (most people underestimate by 30% how many calories they eat in a day), but don't kill yourself over it. Focus on eating healthy foods, getting enough protein, and lift weights. Cardio is important for overall health, but you aren't going to burn enough calories for it to be a major source of weight loss. Lifting will make you feel better (fewer achy joints, easier to get up) and it's a lot more fun than cardio. If you are still gaining weight, cut your calories more. Weight gain is very personal and you'll need to spend time figuring out where your calorie intake needs to be. Age, genetics, etc. all play a role so there is no one-size-fits-all number to aim for. I used to be able to eat 3500 calories a day and not gain weight. Now in my 40's if I eat more than 2500 I put on weight.
Also, don't beat yourself up if you "have a bad day" and eat too much. Fitness is a lifelong goal, and eating a bag of chips one day isn't going to erase all of your work. Just try to have more good days than bad.
I think the missing pole in the tent of weight loss is that we don't acknowledge the psychology of it. Everyone who is overweight knows that they should eat less and move more. What always gets lost is the how. How do I consistently do this in the face a stressful life and constant time pressure? Everyone can walk past a tray of cookies once at the beginning of the day. After a stressful meeting where you were yelled at by your boss? No so easy and you may even eat two.
Like you said, exercise is important for overall health but is a horrible way to lose weight. We are going to eat cake at lunch because we claim we will workout later (but then don't). Exercising takes time to do, to change, to shower, to travel. People are likely to overeat after exercising because they feel famished even though they burned a fraction of the calories they think they did. I think people are probably better served with intermittent fasting and trying hard to control their grocery shopping to keep binge-able foods out of the house. The challenge here is if you are the only person in the house trying to lose weight.
We need a better life hack to lose weight in the 21st century. We are going to lie to ourselves about what we will do or why we didn't. This is actually the brilliance of the Planet Fitness pricing model. The majority of their customers barely go but for $10/month you can lie to yourself that you are "trying" and it is cheap enough to prevent cancellation. I think this is why people have initial success on WW or NutriSystem because it takes a lot of the mental load away. Don't think, just follow instructions.
> Cardio is important for overall health, but you aren't going to burn enough calories for it to be a major source of weight loss.
You need to build the stamina to keep it up. But assuming you can maintain a moderate to strenuous pace for 30 minutes you can burn off a small meal's worth of calories. An hour of moderate running can be around 600 calories for an adult male.
Food is one of my sources of enjoyment and comfort. I've made it a point to notice that enjoyment. The enjoyment comes in the first few bites of food, so really that's all you need. Comfort is harder, I'm still working on that.
Also, YOU WILL BE HUNGRY at some points. That is normal. You will be hungrier if you eat a lot of sugar. (This is my experience and not medical advice)
I wonder if there have been 'good' studies into the human experience of hunger. It's extremely subjective, so I can't imagine it would be easy to do in the first place and near impossible to replicate.
> Cardio is important for overall health, but you aren't going to burn enough calories for it to be a major source of weight loss.
I am sorry but this claim doesn't make a great deal of sense. For example, running expends about 1 kcal/kg/km [1,2].
On a personal note, I went from 105kg to 75kg body weight by doing endurance sports (for the avoidance of doubt, it was all fat loss with localised gain of muscle mass). I have a record of all workouts and almost-daily weigh-ins for 6+ years, and there's a very high degree of inverse correlation: during periods when I run/bike more, the weight goes down, and vice versa.
It’s important to note that all running (or similar exercise) is not created equal. If you are over weight and you start running to lose weight it probably won’t work because your heart rate will likely hit the roof when you start jogging and thus you will be using the anaerobic system - burning sugar. This is the opposite of what you want to be doing. Instead, unhealthy people who need to lose weight should firstly get a HR monitor and only exercise below their aerobic threshold. This burns fat which is what they need to do! If they continue doing this, they’ll be able to move faster at the same HR and also improve their fat burning capabilities. This is how they will lose weight. It will take a lot of time and patience because initially they won’t be able to run because the HR goes too high.
Those who start running with high heart rates likely won’t see any weight loss and furthermore, the sugar burning of the anaerobic system will guide you towards eating more carbs and sugars.
I’m not an expert by any means but weight lifting is the opposite of what you need to do to lose weight as it always uses the anaerobic system.
I agree with everything you write, but this is very subjective:
> and it's a lot more fun than cardio.
I, too, try to lift weights regularly, and acknowledge that it's important for health. But I detest doing it. Running, on the other hand, is incredibly rewarding for me and gives my brain a wonderful "reset" that I sorely miss without it.
Sensible advice all around. I would just replace “gaining weight” by “gaining fat”. If you are lifting a lot then you may get heavier on the scale while losing fat. Attend to your waistline rather than the scale.
I sit all day in front of a pc or computer. If I don't work out, 400c calories is my weight gain threshold. You can even get away with guestimating calorie intake but what most people miss is when they think everyone burns 2500 cal/day just being idle. I wish I could eat even a 1000 ! Also, for weight gain/loss, idle burn means nothing, what you do with the surplus or deficient calories is what matters.
Cardio (especially running) is a major source of burn. Curious how you came to that conclusion. Yes, over the long term lifting is better because more muscle = higher resting metabolism = higher passive burn but in the short term, unless you’re doing high rep/highly hypertrophic exercises, cardio is the way to go.
Anecdotal reports here: I got diagnosed with Type II diabetes in the spring, after many years of being overweight. I've had a lot of success in losing weight (about 10 lbs a month), and while it is too early to make any claims, here's what I've found:
- The continuous glucometer has been very helpful. I've made a big effort to keep glucose down around 100 most of the time. For me, anyhow, this will almost automatically cause weight loss -- I just don't find it possible to eat enough of non-sugary foods not to lose weight.
- Fiber makes a huge difference. Fruit results in much slower glucose rises than, say, bread.
- Walking about an hour a day, on average, also helps. I don't think it's primarily because of the calories used (modest) so much as it keeps blood glucose in control, and that reduces the insulin spikes that create hunger.
All of this makes me think it might be controlling insulin spikes that really matters. It's not a "keto" diet, per se, but controlling blood glucose has somewhat of that effect.
This sounds every much like my experience. After being diagnosed with diabetes and greatly reducing the carbs in my diet, I lost around 25% of my body weight over about eighteen months. (Overall I'm down a third from my peak weight ten or so years ago.)
I don't make a special effort to "diet" in the sense of eating less food, I just watch my carb intake. It's like I'm back in high school, in the sense that I don't put on weight even if I overeat (as long as I keep the carbs reasonable).
I don't necessarily think it's the diet for everyone, but it is certainly the right diet for my body.
A calorie is a measure of energy used, for example there is a direct conversion to kWh. If your body uses more energy than you eat, it must burn fat (weight loss). Our bodies aim to be efficient and won't expel energy, so if you eat more than you burn, you will gain weight. This is true regardless of macronutrient composition.
Calories are therefore at least a necessary consideration in diet and a healthy weight, but calorie consumption alone is by no means a sufficient measure of a healthy diet.
> If your body uses more energy than you eat, it must burn fat
This is totally wrong. The body can also slow down your metabolism, twitch less, think slower (if you had read the article you'd see this is addressed), decrease the effectiveness of your organs, not to mention "eat" some of your nonfat muscle mass.
The people advancing the CICO idea have obviously never struggled with their weight. It is super clear to me as a person who has bounced back and forth between fit to overweight for my entire adult life that there is nothing I could ever do to be as "skinny" as the skinny people I know, all of whom eat and drink way more than me, and usually don't exercise at all.
CICO is not real advice, it's telling people to develop eating disorders, i.e. starve themselves. And for what? To bolster the ego of you and the ~60% of people who are naturally less likely to accumulate body fat, who like to believe they are just smarter or know something about nutrition that people like me don't. But it's exactly the opposite. I know more about nutrition than any of my skinny friends. Social pressure has demanded that I do so. It doesn't actually help, and the smugness of commenters on HN doesn't either.
> if you eat more than you burn, you will gain weight
The converse isn't necessarily true: if you eat less than you burn, you might not lose weight but instead your body adjusts how much you burn.
Calories are amount of energy... released as heat when the food is burned. Or rather, the numbers you see on food products is some value derived from food composition. Anyhow, this is no way directly related to how much of resources your particular body will extract from food.
Counting calories has a benefit of making you aware of your habits, but dietology is not as simple as arithmetic.
If you read the article, you'll notice that this fact is acknowledged there. The issue is that energy in and energy out are not so simple as the Nutrition Facts make them seem. For example, different amounts of energy are consumed in the process of digesting various foods, and some energy is excreted undigested, in a way that depends on the food and the person. Similar complexities apply on the "calories out" side, where a large fraction of your energy expenditure is not directly controlled by your choice of activities like exercise. Ultimately there is some arithmetic of calories in minus calories out, but it is not captured by the simplistic calculations that are normally done.
The whole point of the article is that measurement inaccuracies and variation in energy extraction efficiency make that information practically useless.
Genetic variation of resting metabolism rate is only something like 600cal/day between the 5th and 95th percentiles.
So yes, a calorie is not just a calorie, but the maximum variation between individuals is such that the refrain, "they eat twice as much as me and don't gain weight while I do" is just not possible.
Just one year ago I lost 12 excess kgs I gained over the previous year by doing nothing but counting calories. Took me 2 months.
Was really easy except having to say no to your desires to eat some more of that tasssssty food or sweeten your daily cup of tea with a chocolate bar. But I overcame myself because I have willpower.
As I understand the the calorie issue, unless the laws of Thermodynamics are proven wrong, titles like 'death of the calorie' are nothing but attention grabbing attempts. If the amount of your inbound energy (in the form of food) is smaller than your energy expenditure, the deficit energy is taken from storage, and there is NO way around it AT ALL.
People often say that you can't burn enough calories to contribute significantly to weight loss, but I don't think this is true.
I went from fat to lean by counting calories and exercising. An hour of hard cycling burns 1,200 calories for me. So assuming my body needs 2,400 cals per day to maintain itself, I can have a 1,200-calorie defecit by eating 2,400 and burning 1,200, or by being sedentary and only eating 1,200. The former is fairly easy to do, is compatible with family meals and a social life and makes me fit. The latter is just miserable.
Salvador Camacho, the subject of the Economist article, has written a significant technical article on the subject. [0]
I'll comment that this point of view is completely in agreement with my personal experience over five decades. Low fat, "low calorie", and "lite" products are the exact opposite of what you want to eat, especially if you want to lose weight.
I first learned of these theories from Michel Montignac, whose advice became very popular in Europe in the '80s. [1] He was followed by many "low-glycemic" diets, e.g. Sugar Busters, "keto", and Paleo.
Gary Taubes has written two books on the subject, one popular and one directed at MDs and other professionals. [2]
The idea is to eat mostly fat and protein, with a limited amount of low glycemic carbs. Avoid high glycemic carbs like refined flour, sugar, and fruit.
I've found over the years that following such a diet while limiting food intake so you stay slightly hungry will result in fat loss. Eating a high fat diet to lose fat is counterintuitive, but it works.
Amazing how an article so long misses expositing the most critical information.
You would never guess that: We know now that saturated fat is not just absolutely fine, but necessary for good health, particularly brain health; that the heart disease epidemic of the last century was caused not by "sat fat" but by trans fat -- margarine, Crisco, "partially hydrogenated vegetable oil" -- and sugar.
You would never guess that: Half of all the sugar you are probably encounter is fructose, which your liver treats as a toxin it must neutralize; and that if blasted with more than it can, by eating (drinking!) it without enough fiber mixed in, it gets cirrhosis and you get sick and, probably, fat too; and that your body does not count the fructose when it decides whether you have eaten enough.
I'm actually confused about the message this article tried to communicate.
Dieting is hard and sticking to a routine that consists of eating less than your body craves for requires a lot of willpower.
However questioning basic principles about how the humans energy system works as if it was an idea some mad scientist came up with is just absurd.
Yes, measuring a calorie is not easy and if you find out after counting calories for a few months that you didn't loose fat then probably drop your intake a little further, until you see the desired results.
A calorie is just a universal measure, but in the end you can use whatever measure you want (cups of rice, grams of potatoes, slices of cheese, mug of milk, egg) to measure your food intake.
If 2 cups of rice and 3 eggs won't cause weight loss then try 1 1/2 cups of rice and 2 eggs next time...
I've longed considered doing a diet based on mass rather than calories, as mass in vs mass out is a tautology. Maybe I should actually try it soon. It would be pretty simple:
1. Come up with a post-meal target weight goal, like say 5 pounds over your current weight, decreasing by 0.1 pounds per day.
2. Before each (significant) meal, weigh yourself.
3. Limit the weight of what you consume to the difference between the target weight at the moment to your current weight.
If the target is sufficiently above your current weight initially and the rate of decrease is realistic, it should glide you into the correct portion sizes for your weight loss goal. Your measurements of the food could even include some of the packaging; as long as that's typical, it'll calibrate accordingly.
Cooking for yourself? Rather than trying to estimate calories from ingredients, just break out your kitchen scale! Eating at a restaurant that doesn't list the calories on menu items? Just pack a scale!
Weight loss and physical fitness is just a never ending battle. You will have small victories and defeats but the main thing is that you keep fighting. It’s a pain in the ass but so is dealing with all the health problems if you don’t. So try calorie counting, keto, vegan, carnivore, whatever just keep working at it. You are unique and what works for you will be as well, hell what works changes year by year also.
My own personal journey just took a turn as I had been trying to lose weight for rock climbing for years and could not cut through a certain weight. It turned out I needed to way reduce my protein intake for a time so I could shed some useless chest/arm/leg muscles, but it took a year or two of super low calorie fatiguing diets to make an adjustment and figure it out.
1. BMI is a good measurement of health. Some of the fittest people I know are classed as 'morbidly obese'.
2. Fat and salt are bad.
3. You need lots of carbohydrates in your diet.
4. All calories are the same. Even that all carbohydrates are the same. Checkout how your body processes glucose vs fructose and how much gets converted to fat.
5. Assuming alcohol has no effect on the processing of food.
6. 'Low-carb' or 'low-sugar' food is definitely good for you. They tend to use Maltitol - you may as well consume sugar [1].
The list goes on. No wonder there is an obesity crisis when 'experts' giving dietary advice don't understand this stuff themselves.
If you want a true dive-in-the-deep-end strategy that will work, try fasting. No, not intermittent fasting where you still eat every day, but alternate day fasting. Or eating every 3rd/4th/5th day. It will suck, but it will dissolve your addiction to food and give you control you never thought you had. Check out Snake Diet (https://www.youtube.com/c/SnakeDiet). Cole is extreme, but he gets results (I think he does consulting via a Facebook group and he frequently talks about successes with clients).
That is the main problem. Obsessing over something makes you tired, it is like obsessing over an ex. It is hard to break a social habit, since you will constantly remind yourself of the good old days when you still did it, and depression/low energy etc kicks in. That has nothing to do with the food, it is just in your head. Doesn't make it easy to fix, but thinking that it is your body going into starvation mode will make it even harder to get over.
I'm really curious about more of those hacks on how to make food digest more poorly (like the dried toast), so your body doesn't absorb as much energy from it.
Do I understand correctly, that the only thing Camacho was measuring were calories, without checking the amount of carbs vs fats vs proteins contained in what he ate?
He ditched his heavily processed low-calorie products and focused on the quality of his food rather than quantity.
It also mentioned that he at a lot of "low-fat" foods. So, my guess is that his carb intake was pretty high. This is exactly why "calories in, calories out" isn't accurate. Your balance of macronutrients is much more important, but total caloric intake still needs to be monitored.
The problem with calorie counting is you're sort of modelling the human body on simple machines, like say, cars.
But the body is actually a complex system, and the core quality of a complex system is adaptation.
This means you can cut calroies below your current burn rate and still gain weight, because your burn rate will change.
To illustrate: suppose you consume 4000 calories a day, with your body burning 3000 of them and storing 1000. Does cutting to 2500 guarantee you will be burning 500 extra calories from your fat storage? Not at all. Your body can easily adapt by burning 2000 calories and storing 500.
Obviously the numbers are just for illustration purposes and I'm not claiming they are realistic by any means.
What you really want is to inroduce changes that make your body adapt into accessing your fat storage for energy.
So if we go back to the above (obviously flawed) example: what you want is to make your body burn all the input you are giving it (even if it remains at 4000) AND on top of that burn, say, 500 calories from its fat storage.
How do you do that?
I can't claim to have the answer, but two things come to mind:
1. Walking.
I've personally lost weight by just walking a lot - with no changes to deit. By a lot I mean several hours a day.
Needless to say, I was single then. It's not really easy to do when you have family and children.
But the point is: exercise. Exercise that requires energy.
The good thing about walking is it's generally relaxing. You can actually walk for 2~3 hours and genuinely be enjoying yourself.
For exercising: I'm find exercise-band based workouts at home to have a similar effect: they use energy but I'm generally enjoying myself when I'm doing them. It's a bit different from weight lifting in that you can easily adjsut the resistance to be just right for your skill/experience/strength level, so that you do get a real workout, but don't feel like your muscles and bones are dying.
2. Hormones.
Cortisol and Insulin.
By eating during a short window (intermittent fasting) you can limit the amount and duration in which your body uses the energy from the food (regulated by insulin).
Working out while fasted (say, after you wake up and before you eat) will teach your body to access its fat storage for energy. And apparently it also increases your metabolic rate for several hours after.
By sleeping well, removing stress, and avoiding coffee, you can reduce the amount and duration in which cortisol is circulating in your body.
The thing about low-calories diets is they feel like stress and increase cortisol, thus sabotaging the whole thing.
Being stressed and not having enough sleep is the surest way to absolutely oblitirate your "will power" and make you want to eat for comform.
Incrase the amount of protein in your food is another thing that apparently helps regulat your hormones in a desireable way. And anyway it's needed if you workout (which you should, if you want to lose fat).
Your description above is not how the body works. To support a mass M must require a quantity of energy E obtained from food. The attempt to alter this model with “loose” ideas about “burn rates” therefore does not make sense.
The mathematics of weight loss is laid out clearly in 20 minutes here:

The former is fairly easy to do, is compatible with family meals and a social life and makes me fit. The latter is just miserable.

Salvador Camacho, the subject of the Economist article, has written a significant technical article on the subject. [0]
I'll comment that this point of view is completely in agreement with my personal experience over five decades. Low fat, "low calorie", and "lite" products are the exact opposite of what you want to eat, especially if you want to lose weight.
I first learned of these theories from Michel Montignac, whose advice became very popular in Europe in the '80s. [1] He was followed by many "low-glycemic" diets, e.g. Sugar Busters, "keto", and Paleo.
Gary Taubes has written two books on the subject, one popular and one directed at MDs and other professionals. [2]
The idea is to eat mostly fat and protein, with a limited amount of low glycemic carbs. Avoid high glycemic carbs like refined flour, sugar, and fruit.
I've found over the years that following such a diet while limiting food intake so you stay slightly hungry will result in fat loss. Eating a high fat diet to lose fat is counterintuitive, but it works.

You would never guess that: We know now that saturated fat is not just absolutely fine, but necessary for good health, particularly brain health; that the heart disease epidemic of the last century was caused not by "sat fat" but by trans fat -- margarine, Crisco, "partially hydrogenated vegetable oil" -- and sugar.
You would never guess that: Half of all the sugar you are probably encounter is fructose, which your liver treats as a toxin it must neutralize; and that if blasted with more than it can, by eating (drinking!) it without enough fiber mixed in, it gets cirrhosis and you get sick and, probably, fat too; and that your body does not count the fructose when it decides whether you have eaten enough.

1. Come up with a post-meal target weight goal, like say 5 pounds over your current weight, decreasing by 0.1 pounds per day. 2. Before each (significant) meal, weigh yourself. 3. Limit the weight of what you consume to the difference between the target weight at the moment to your current weight.
If the target is sufficiently above your current weight initially and the rate of decrease is realistic, it should glide you into the correct portion sizes for your weight loss goal. Your measurements of the food could even include some of the packaging; as long as that's typical, it'll calibrate accordingly.
Cooking for yourself? Rather than trying to estimate calories from ingredients, just break out your kitchen scale! Eating at a restaurant that doesn't list the calories on menu items? Just pack a scale!

My own personal journey just took a turn as I had been trying to lose weight for rock climbing for years and could not cut through a certain weight. It turned out I needed to way reduce my protein intake for a time so I could shed some useless chest/arm/leg muscles, but it took a year or two of super low calorie fatiguing diets to make an adjustment and figure it out.

1. BMI is a good measurement of health. Some of the fittest people I know are classed as 'morbidly obese'.
2. Fat and salt are bad.
3. You need lots of carbohydrates in your diet.
4. All calories are the same. Even that all carbohydrates are the same. Checkout how your body processes glucose vs fructose and how much gets converted to fat.
5. Assuming alcohol has no effect on the processing of food.
6. 'Low-carb' or 'low-sugar' food is definitely good for you. They tend to use Maltitol - you may as well consume sugar [1].
The list goes on. No wonder there is an obesity crisis when 'experts' giving dietary advice don't understand this stuff themselves.

If you want a true dive-in-the-deep-end strategy that will work, try fasting. No, not intermittent fasting where you still eat every day, but alternate day fasting. Or eating every 3rd/4th/5th day. It will suck, but it will dissolve your addiction to food and give you control you never thought you had. Check out Snake Diet (https://www.youtube.com/c/SnakeDiet). Cole is extreme, but he gets results (I think he does consulting via a Facebook group and he frequently talks about successes with clients).

That is the main problem. Obsessing over something makes you tired, it is like obsessing over an ex. It is hard to break a social habit, since you will constantly remind yourself of the good old days when you still did it, and depression/low energy etc kicks in. That has nothing to do with the food, it is just in your head. Doesn't make it easy to fix, but thinking that it is your body going into starvation mode will make it even harder to get over.

But the body is actually a complex system, and the core quality of a complex system is adaptation.
This means you can cut calroies below your current burn rate and still gain weight, because your burn rate will change.
To illustrate: suppose you consume 4000 calories a day, with your body burning 3000 of them and storing 1000. Does cutting to 2500 guarantee you will be burning 500 extra calories from your fat storage? Not at all. Your body can easily adapt by burning 2000 calories and storing 500.
Obviously the numbers are just for illustration purposes and I'm not claiming they are realistic by any means.
What you really want is to inroduce changes that make your body adapt into accessing your fat storage for energy.
So if we go back to the above (obviously flawed) example: what you want is to make your body burn all the input you are giving it (even if it remains at 4000) AND on top of that burn, say, 500 calories from its fat storage.
How do you do that?
I can't claim to have the answer, but two things come to mind:
1. Walking.
I've personally lost weight by just walking a lot - with no changes to deit. By a lot I mean several hours a day.
Needless to say, I was single then. It's not really easy to do when you have family and children.
But the point is: exercise. Exercise that requires energy.
The good thing about walking is it's generally relaxing. You can actually walk for 2~3 hours and genuinely be enjoying yourself.
For exercising: I'm find exercise-band based workouts at home to have a similar effect: they use energy but I'm generally enjoying myself when I'm doing them. It's a bit different from weight lifting in that you can easily adjsut the resistance to be just right for your skill/experience/strength level, so that you do get a real workout, but don't feel like your muscles and bones are dying.
2. Hormones.
Cortisol and Insulin.
By eating during a short window (intermittent fasting) you can limit the amount and duration in which your body uses the energy from the food (regulated by insulin).
Working out while fasted (say, after you wake up and before you eat) will teach your body to access its fat storage for energy. And apparently it also increases your metabolic rate for several hours after.
By sleeping well, removing stress, and avoiding coffee, you can reduce the amount and duration in which cortisol is circulating in your body.
The thing about low-calories diets is they feel like stress and increase cortisol, thus sabotaging the whole thing.
Being stressed and not having enough sleep is the surest way to absolutely oblitirate your "will power" and make you want to eat for comform.
Incrase the amount of protein in your food is another thing that apparently helps regulat your hormones in a desireable way. And anyway it's needed if you workout (which you should, if you want to lose fat).
