2. Losing weight is to reduce the fat content in the body. Fat is the main energy storage part in human body. Anyone who has studied biology knows that the energy (atp) stored in muscle will only be released before fat can be decomposed for energy supply. Therefore, two aspects of losing weight include: 1) preventing the formation of fat, that is, consuming less energy and consuming more energy, resulting in no redundant energy storage; 2) Strengthen mental and physical labor and be forced to decompose fat. Because muscle energy is insufficient, it will hurt, and if energy is insufficient, it will be hungry and greedy, so this process requires perseverance.
