The total calorie intake of human body every day is about 1800 ~ 2000 kcal, and the calories consumed are about 1/7 of the total calorie intake. In addition to the calories consumed in normal life, walking 10 thousand steps a day can just consume excess calories.
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.
