Calorie deficit and losing weight

A calorie deficit means eating less energy than your body uses. A gap of 300 to 500 calories a day is a common place to start. The scale will usually move slower than the math says, because water, salt and digestion shift your weight from one morning to the next.

Read on for how to set a deficit you can live with, why very low intakes tend to backfire, and how to watch a weight trend instead of a single weigh-in. Calsa keeps your meals and your weight in one place, so the trend is there when you want it.
