1, thermal effect

Just as computers consume electricity and trucks consume oil, so do human daily activities. Heat not only provides energy for people's exercise, daily work and life, but also provides energy for human life activities, blood circulation, breathing, digestion and absorption. People who lose weight can burn fat through exercise, which can accelerate calorie consumption and achieve the goal of healthy weight loss.

2. Heat source

Heat produced by fat = 9 kcal/g.
