Wilderness healthy lose weight

Quite simply, heat is a manifestation of energy in our body. Exercise consumes energy. We also need energy for a series of physiological activities such as human metabolism. Energy comes from food. If we eat more energy than we consume, the remaining energy will be stored as spare energy and turned into fat in case of possible energy shortage in the future. Dieting is because eating energy is less than consumption, so the body automatically uses excess energy and fat, and people will lose weight. What's the heart rate? I hope this helps.
