My point is that all these factors are real, and they do tip the scale, but at the end of the day, how much you eat determines whether you gain or lose weight.

I'm not saying other factors can't make a significant difference. (genetics and epigenetics play a role.) I'm also not saying that it's easy. (food, especially fast food can light up people's brains in a way that mirrors drug addiction.)

But if you eat less while burning the same number of calories, you WILL lose weight. That's not an opinion, it's a law of physics.

I hate to agree with southsamurai, they downvote nearly every post i make, but... they have some truth here.

If you want to lose 1 lb in a month, or gain 1 lb, you need to consume or burn 3,500 calories. Or 116 calories a day. Or 38 calories per meal… Easy right? … In the US, calorie estimates are allowed to be off by as much as 25%, and that’s just packaged food, forget any restaurant or line cook being exactly precise with portions… So for 2,500 average daily diet, over three meals, the margin of error is 208 calories. Your target is 38 calories. You’re trying to do something within the margin of error of all of your estimates. Calorie counting is a very difficult game to do! The deck is stacked against you. This is why it’s important to allow the homeostasis machinery in your body to handle all of this through satiation. It’s going to do the right thing if you let it

This is not in support at all. In fact, it further supports moonlight's and others' position. You cannot escape physics. That the numbers on the back of cereal box lie to you is not a get-out-responsibility card. You adjust your intake until you start losing. It is stupid simple. You body is a PID controller. And you need you learn how to operate it.

Does it make it more difficult to accomplish goal? Yep. Does it prevent you from actually doing it? Nah.

The thermodynamics doesn't change, its true.

But the body is an amazing homeostasis machine, letting the body function properly will let it self regulate with all of its internal feedback loops.
