What happens when the body uses more energy than the calories it takes in will produce?

Answer 1

I'm pretty sure any extra calories get stored in your body for fat, growth, heat, energy and whatever else. You won't get fat just because you eat 2500 cals daily and only burn 2000 (which is actually fantastic). You can keep track of how many calories you burn, but not really how many you use. Burning is usually what people say when you exercise. example: you burned 1000 calories in your bike ride and Ice Hockey game today (mind you, if its cold enough to play hockey, you shouldn't ride your bike!). But using calories is different. You use calories for laughing, sleeping, moving, body heat, fat storage and MANY other things. It's basically your body's gasoline. So if you consume 2000 calories and burn 900 through exercise, your body will probably find it's own uses for hundreds more. And chances are you'll have a few hundred (or a thousand) left over. That's okay though you won't pile on pounds. 21st Century humans are not that active it happens 90% of the time! When you use more than you consume, your body eats away at it's own reserves- first your fat (bad), then muscle (critical), then your internal organs, killing you. The reason humans get really fat is because we don't use as much energy as we used to in the effort to get more energy. Cave men (example) used 1300 cals in a day hiking and hunting, and there catch (shared up) provided each one with 1800 calories. that's why cave men were so strong; it's all about how close the amount used and the amount consumed is. You HAVE to consume at least a little more than you use or you'll die. The answer to this question is, as long as you don't consume TOO much more, you'll be fine and healthy!
