Why do you gain weight when you eat less?

Answer by  Loyola (378)

If you are doing "starvation" dieting where you drastically reduce calorie intake, your body responds by slowing down your metabolism to save calories-a survival response. To avoid this problem, eat at least 1200 calories daily and divide them up into many small meals. This will help keep your metabolism up.
