The obsession with the laws of physics in this context is some kind of "in joke", or a weird appeal to unarguable authority. I've even seen posters talk about the Laws of Thermodynamics (those who could spell it) as if they are practically applicable to an entire human body.

"Calories in, calories out" is just one example. It's not untrue, but it's not very useful. You are not a bomb calorimeter. There isn't a calorie detector in the whole human body. Yes bodybuilders measure their food very precisely. Yes you can work out the calorie equivalent. But so what? Most people do not have the discipline of a bodybuilder. They don't have those goals either. They just want to lose some flab.

"Eat less, move more" is another trite bit of uselessness. The root cause for most overweight people is a poor diet. That's how they got fat. If they eat less of the same they will just be hungry. If they move more they will be even more hungry. So what are they going to do, permanently starve themselves? The obesity stats suggest otherwise.

In the real world the calorific measure is just "roughly how much food you ate". And yes it is not a very useful focus. Just a "sciencey sounding number" for our post religion era.

A single focus on "carbs" is not really focussing on the root cause either. Your body can get energy from fat or protein. But in practice going keto on real food will cause most people to lose weight and keep it off successfully. Which is what most fat people actually want.

tl,dr - OP, I would not try to focus on either calories or carbs as a simple in/out problem. Your body just doesn't work like that. You can control your weight with diet alone, and cutting carbs or going keto is very successful. But it is more a case of "eat better" than "eat less".

I know a fair number of people who track their calories regularly and accurately enough to lose weight to the nearest pound within a given timeframe. Most serious sportsmen/women do exactly that. However the biggest variable for non-sportspeople is they lack the discipline to go that far.
The stat I heard yesterday (DAOC Podcast re Ozempic) was that only 10% of people who diet keep the weight off at 2 years.

Average weight loss at the 2 year mark was ~ 2lb!

How do I get rich/out of debt?

Same as 'spend less than you earn'. True. But not so 'useful'.

Eating better ftw. thumbup

Eating proper whole foods is for the most part more satiating and so ultimately you do eat 'less' (fewer calories) than super palatable ultra processed foods which are very calorie dense and not satiating. IIRC, those who regularly consume UPF typically consume 500kcal additional per day than those who don't.

I've posted this before, but I do rate Ben Carpenter for his advice when it comes to diet/weight loss:

If you reduce everything down to the extreme then yes, calories in/out works in a laws of science sort of way.

It's pretty meaningless to anyone in the real world though, because there are so many variables in both in and out that can't be measured outside a lab that 99% of attempts to track it are pretty much random.
Not random, just not 100% perfect.

I don’t think that anyone denies that eating too much gets you fat. If that is true then it’s just a case of how each individual measures or judges how much is too much.

Some people just either have the discipline, sense or judgment to stop eating when they should, others need help which may just mean using a smaller plate or could be an effort to measure accurately.

That's pretty much what proper calorie counters do. They weigh every item of food/ingredients they are eating.

They are absolutely fastidious when it comes to food prep and measuring macros.
Food prep is irrelevant unless they only ever cook their own individual portions and lick the pan and cooking utensils clean afterwards!

Let's say you're one of these weirdos and you're sitting down to a nice beef stew for your family dinner...

1. You measure the total calories going into the stew. You might possibly be able to get that accurate to within about 5-10% either way, but no more than that, if only because of the variation in the amount of fat in the beef, even if it's labeled as "xx% fat".

2. You then have to weight the stew overall after you've made it (proving how much fun you can be at parties) so that you can work out the calories per 100g or whatever after evaporation has done its thing.

3. Now you ladle yourself out a scrupulously measured portion. Let's say you've taken 20% of the total weight of the stew and that comes in at 312g.

4. Great! We've got 312g of stew, and we know precisely (well, to within 10% or so) how many calories there are in 100g of our stew on average, so we can work out what's on our plate, can't we?

No, of course we can't! hehe

Unless you can guarantee that your 20% of the stew contains precisely 20% of each ingredient that went into the pot in the first place, then each 20% mass is going to have a different share of the total calories in the whole stew!

You can waste as much time, effort and money as you like on trying to precisely record your calories but you're only going to get it right occasionally by luck.

A lot of high level athletes will buy in prepped meals that are already measured and balanced in the way they require.

Their nutritionist can track their meals down to the last calorie.

I'm just quoting you as an example and I don't in any way mean to single you out, but this argument that the amount of calories you eat has no effect on weight gain or loss is simply wrong.

People do not gain weight because their diet is "bad". They gain weight because they consume more food than they need and so their body stores it as fat. Conversely, people lose weight (be that fat or muscle) because they do not eat enough food to fuel their body.

That's it. There's no such thing as a good or bad calorie. Everything else your talking about that you think is linked to weight loss or weight gain, is just you over or under-eating.

You can count calories, you can count macros or anything else you like but your body absolutely does know exactly how much it needs and it stores or uses that energy appropriately.

I'm not arguing that you can't lose weight by cutting something out, but all you're doing is reducing your calorie intake. You cannot gain weight if you are not eating more calories than you expend.

Ketosis is different and isn't sustainable over a long period so exclude that method. If you came out of ketosis and went back to your usual diet which included overeating, guess what? You'd put weight back on.

If you have naturally found a balance of food that allows you to maintain your weight then that's great, but counting calories is the easiest way for those that haven't or don't understand nutrition to start and get to that stage eventually.

I think you're slightly missing the point in re tracking. Of course it can't be 100% accurate but if you're shooting for a 500-1000 calorie deficit it will get you in the ball park.

My slightly ridiculous example of inaccuracy is I make my own sourdough. The only ingredients are flour salt and water. Each loaf contains 440g of flour. Pretty straightforward to calculate the calorie content of my bread you'd think. 440g of flour is 1514 calories. So weigh the loaf and you can work out how many calories per 100g. Except that the yeast and bacteria have been gobbling the flour to make CO2 whilst it's been fermenting. I have no way of knowing the calorie content.

Other foods such as nuts are literally shat out depending on how well you crunch them there's no way of knowing how much you absorb. Our individual gut microbiome will take its own energy from the food you eat robbing you of calories - some fat people are doing faecal transplants so they can get some of the greedy bugs which skinny people are hypothesised to harbour.

Despite this tracking does work for some people although the maths is a little suspect. It makes them accountable for what they eat; can avoid food items that are relatively calorie dense but not filling and gravitate towards things that are filling and less calorie dense (coloured veg in the main). This naturally takes you a the real food, whole food diet. As long as the scale is going in the right direction there's no need to over think it. If you're getting stuck then you need to have a look at what you might be under or overestimating and make an adjustment.

The exercise thing is more tricky as you need to fuel for and to recover from exercise but device or not, most of us will overestimate what we've burnt and underestimate the compensatory drop in calories burnt which happens after exercising. My policy is to make sure I fuel appropriately before and during (rides or runs of > 1 hour), try and eat a normal meal after as soon as possible, not let myself get hungry and not eat back the whole calorie deficit.

Meals out are tricky. I think you can either estimate the calories (probably near to daily allowance for woman trying to lose 500g/week or man trying to lose 1kg/week for a typical plated pub meal); bank previous days' calorie shortfall or accept that you are going to get to goal weight a day or two later.

I think if you're overweight and can follow a quality Mediterranean (or other peasant) type diet without tracking and move a bit more then you'll probably lose weight. What works is whatever makes you disciplined, accountable, consistent and can be sustained over a long time - for some this is Weight watchers; others fasting; others restriction of a food type (eg ketogenic) and others tracking.

Yes, in many situations that is correct. That is what successful dieting allied to competitive sport involves. Of course competitive athletes often have nutritionists on hand for advice. I know/have known many amateur sportsmen/women over four decades who can very accurately track their calories and weight.

Post just reads like any other looking to exclude overweight people from responsibility for their health.

Like any other physical parameter: establish a goal, work out your baseline, set a plan for getting there. Thing is that calorie counting doesn't need to be 100% accurate, most people own a mirror.

Sssh don't tell anyone it's that easy. Remember it's a conspiracy to keep everyone overweight.

I wouldn't say a mirror is a good way of tracking weight loss.The change is so gradual you wouldn't notice the difference from 1 day to the next.

Yes, that's another way. People's approach to calorie control and weightloss varies in discipline of application but if you know yourself well enough there's loads of ways to measure change. The science is still the same though.

To lose/maintain, I've found fasting is easier than running. So you can go fast without going fast. biggrin

Worthwhile figuring out how you can incorporate 24 hour fasts into your life and getting round the barriers to doing so. Only posting this bit to avoid unnecessary arguments which also get in the way of you losing weight/fat and keeping it off.

So, if my BMR (calculated) is 2,120 then 1,600 kcal per day should be a reasonable deficit for weight loss. So I am going to consume 4.1l of full fat coke per day. 'cos it's all just calories, innit? There's no such thing as a bad diet.

silly

The reality is that any unidimensional simplification is only useful if we accept the limitations of the analogy and talk in good faith.

By the way, it is perfectly possible to remain in ketosis over a long period. Our ancestors did it without trying.

The mirror is a great way of seeing improvements, people obsess over what the scales say when composition is far more important, losing weight is all well and good but increasing muscle especially as we get older is far more important

Hence the absurdity of anyone suggesting it as a straightforward thing for anyone else to do to lose weight.

There was some prof in the US that did something similar, I think he lived off a calorie restricted diet for a period of time - he only ate donuts.

He lost weight.

There is a use to it in a general sense, to make sure you’re catching all the nutrition you need for what you’re doing.

Anyone who thinks they’re recording everything when they’re eating normally is lying to themselves, but that doesn’t mean the technique has no use.

Broadly speaking true, but your body will respond to you reducing your intake by slowing your metabolism to try and maintain energy stores as a defence mechanism.

The further you go, the more you'll need to reduce calories to keep losing weight, and not just because you're carrying less weight.
