It's true that some people burn more energy than others, and that those people can (in fact, must!) eat more to maintain a steady weight. That's what "energy balance" means: energy consumed minus energy used! Maybe you naturally burn 10,000 calories a day. If so, you need to eat less than 10,000 calories to lose weight, and more than 10,000 calories to gain weight. More likely, you burn 2000 calories a day, same as the rest of us, and so you should eat less than 2000 calories a day if you want to lose weight.
No matter how much you talk about the different ways the body metabolizes food, or all the different ways different peoples' bodies work, you can't change the fact that to lose weight you personally must eat fewer calories than you personally burn. If you eat fewer calories than you burn, you will lose weight. It's a fact.
