The gist of the video is that the brain is a really powerful regulator of how much energy you use. Do a ton of exercise and it’ll find energy savings elsewhere.

But as you build up muscles you constantly need more, even when not doing anything

I’m not sure I understand your point.

Each human has an amount of calories they burn even when they do nothing (the amount of calories you burn obviously goes up when doing things)

This basic calory burning or whatever it’s called in English is influenced by a few factors, one of them is how much muscle mass you have, those muscles need energy to simply exist, even when not exercising.

So people who regularly do sports indeed can eat more - they not only can eat more, they have to eat more (even when they do the exact same things as someone with less muscles)

Yes. But this is talking about trying to lose weight. The video is saying there seems to be a hard limit on how much you can burn over what you eat as long as you’re eating the minimum requirements for your body. Before burning fat your brain will make subconscious changes to your behaviour (and even automatic systems like your immune system) to use less energy.

Yeah the video talks about that. Compare two people with the same muscle mass, one has a sedentary lifestyle while the other has an active lifestyle. They both burn about the same calories in a day. Many people are only doing cardio training when they train to lose weight. Because they don’t want bigger muscles. Thus they don’t lose any fat anymore after the first few months since their muscles hardly get any bigger.

A really fat person who wants to lose fat in a reasonable amount of time needs to gain serious muscle mass to lose weight without reducing their caloric intake. While if they just adjust their diet they will lose fat much fast.

Cardio alone will allow you to lose weight for sure. If you have a net higher energy expenditure through a day, you will burn more calories and if the diet stays the same you will lose weight.

The argument is just about how you increase that expenditure. Having more muscle mass and just existing will burn more calories and regularly doing cardio will burn more calories.

Will you be more lazy and thus expend less ‘base’ energy on days that you do cardio? Probably. That just means that you have to do enough cardio to offset that difference.

You know what’s even easier than both cardio and gaining muscle though? Not drinking calories, using lean ground beef instead of full fat, replacing some of the carbs in your meals by more veggies, eating fruits instead of sugary snacks, getting more protein in your diet, … If you’re consuming a fuckton of calories a day, there’s no amount of muscle that’ll allow you to lose weight.

The video is pulling from research which says you won’t. Your body wants to hold onto fat badly. Your brain will make behavioural shifts to reduce energy expenditure when you’re not doing cardio.

Will you be more lazy and thus expend less ‘base’ energy on days that you do cardio? Probably. That just means that you have to do enough cardio to offset that difference

Again no. Your brain will just down shift your energy use more. It’s going to win because it’s had millions of years evolving to do exactly that.

You know what’s even easier than both cardio and gaining muscle though? Not drinking calories, using lean ground beef instead of full fat, replacing some of the carbs in your meals by more veggies, eating fruits instead of sugary snacks, getting more protein in your diet, …

Which is the exact point of the video. Exercise for other health benefits, diet control for loosing weight.

As far as I understood the video this is true but not right away, our body ‘normally’ wastes a ton of calories on things like excessive immune responses so at any level of fitness between modern office worker and hunter gatherer your calorie requirement is unchanged as its just shifting that calorie consumption back to where its supposed to be. Past that point yeh you need a higher baseline amount to keep going.

Building muscle raises your daily maintenance calorie requirement.

Raising your daily burn rate makes it easier to be in a calorie deficit.
