Exercising and sweating can theoretically lead to weight loss. This is because sweat is excreted from the body and takes away some of the energy. In clinical practice, sweating for a short period of time cannot achieve weight loss, or fat burning. Only through prolonged exercise can the body’s fat be burned, because a short period of sweating is mostly consumed sugar in the body, while only prolonged exercise can convert fat into sugar, which can then be consumed, so that fat can be burned for the purpose of weight loss. The reality is that to lose weight, sweating is inevitable, but it is important to grasp the rhythm and time. It is best to consume through aerobic exercise that lasts more than 45 minutes, which will achieve the purpose of weight loss.
