How dieting works
In a nutshell, when you consume more calories than it takes to run your systems (lungs, heart, breathing), and doing physical work, you store fat and gain weight. When you spend more energy than you consume with food, you lose weight. Because your body needs energy to function, breathe and stay warm, it is not recommended to drastically cut down on calorie consumption.
