Bitching about down votes doesn’t magically make you right. You’re being downvoted because what you said is idiotic.
It has a lot to do with what’s in the food. Sure, if you eat nothing but 1500 calories of Twinkies every day, when you were eating 3000 balanced calories, you’ll lose weight.
That is about 12 Twinkies. Not even an entire box of Twinkies. And that’s all you get to eat in a day.
It would be much easier to reduce calories if half of them were from vegetables and the other half from meat. Feeling hungry has a lot to do with why diets fail. You can’t just apply physics to the human body and expect emotional and hormonal changes not to have an impact on the choices that human makes.
