People over complicate this stuff way too much. Special nuts and eating during a solar eclipse, concoctions of synthesised drug lab fat and protein mixes void of carbs (which actually help you lift weights).
Calories in and calories out; pretty much what rev said.
There are no magic calories that appear on the body without you eating. The body also cannot move without consuming calories. These laws of biology are non negotiable. There are other factors that affect how this process works, the 1%ers rev talks about, but the process itself is static. And people who say they can't lose weight are ALWAYS doing one of two things: 1. Eating crap food or too much food, or 2. Shit exercise or not enough of it. The rest of the little tricks like timing of meals and quantities and all that are just excuses and mind tricks trying to get past the stuff that actually makes a difference - good food and good exercise.
Take shit food out of your diet. You know what this food is, your mother taught you when you were 5. It doesn't taste as good as the bad food. If you're not losing weight after that, then eat less food or lift more and heavier weights. People think just because they're at the gym doing exercise means they're making up for the bad food they've eaten?
Cardio burns fat, but nothing like an intense weights session that puts the body into a catabolic state, using calories long after you stop exercise. People find it hard to believe that I complete on average only 2 x 40 minute sessions of intense weight lifting a week and eat what I eat. Fast metabolism usually gets the credit for it, because I guess it's easier for them to blame fat ass genetics than it is to get off that fat ass and make changes.
