Running consumes 300 calories, which is equivalent to consuming about 42 grams of fat. Calories are units of energy calculation. If 1 day consumes 300 calories, it is equivalent to 42 grams of fat according to the energy formula. This is a rough estimate, and the specific value may vary from person to person. In addition, while running to lose weight, we should also pay attention to controlling the amount of food to ensure that the calorie intake is lower than the calorie consumption, so as to achieve the purpose of losing weight.

It should be noted that the heat mentioned here refers to the unit of heat in food, not the unit of energy consumed by the human body. In the field of nutrition, heat is used to express the heat contained in food, while the energy consumed by human body is expressed in joules or watt hours. Therefore, when discussing the energy consumed by the human body, we need to pay attention to using the correct energy unit.
