Well, technically not nothing. Exercise can get you a few hundred extra calories burned a day, which will have an impact.
But the sentiment is correct. 90% of losing weight is eating less calories. Exercise is still good though, without it a lot of the lost weight is going to be muscle.

Not if the increased appetite after the exercize (and the "I exercized for now I'm entitled to some nice food") gets you to gulp more at lunch/diner....
Of course it does. Or I should say it can. It's burning calories. If calories in are less than calories used, you lose weight. What is true is that it's very easy to eat more calories than you can practically hope to burn off by exercise. The people doing physical labor for 10 hours a day who are still fat are probably eating Big Macs, Fries, and 48oz cokes for lunch and having 3-6 beers after work.
Not really. The human body doesn't have a power saving mode like computers do. The vast majority of burned calories are burned simply by the body existing and keeping its metabolism running.
This x100. I known plenty of people who spend the day on their feet lifting heavy things, and are classed as overweight. I sit at a desk all day and I'm skinny AF.
I really watch what I eat.
Never heard of this potato diet before... Human metabolism is complex!
> Your physical labour people probably consume more calories than they use.
It really comes down to this at the end of the day. Assuming someone is reasonable about what they eat (not garbage), if you consume more than you expand, you're gaining weight that is mostly fat, unless you're doing some type of resistance exercise like barbells, which would result in both fat and muscle gain if, again, you don't eat trash diet.
Completely. It’s also about the psychological impact. Building physical strength up through exercise has mental health benefits too which are added to the feedback loop of trying to fix your head, which is the real issue.
I can run a 5k now. Now that has some calorific consequences.
Yes and then people who don't have their diet under control will eat all the calories back up (because of the bigger deficit and exhaustion) and then some.
So no I would say you should get your diet under control first.
Exercise does nothing in losing weight. (If you've seen the people doing physical labor for 10 hours a day, you know they're not necessarily thin.)
