If the weather gets cold and people's bodies get cold, they need a lot of heat to consume. In winter, the body's fat will burn the body's heat.

Therefore, when people's bodies are cold, they consume more fat. Obviously, losing weight in winter is better than losing weight in summer. Losing weight in hot weather is mostly sweat. It is the water in the body, and when you lose weight in winter, the sweat it excretes must have the body's heat before it can be excreted.
