This document discusses how to lose weight while sleeping by fueling your "fat furnace", or basal metabolic rate. It recommends three steps: 1) Eat enough to trigger adaptive thermogenesis and avoid starvation mode, 2) Eat a high-carbohydrate diet to take advantage of the thermic effect of food, as carbs burn faster than fats, and 3) Engage in regular exercise to raise your metabolic rate, even when not exercising. Following these three steps is said to keep the metabolic rate high and help burn calories around the clock, including when sleeping.
