Understand that body fat stores energy, and this energy can be measured in kilocalories (kcal), which are commonly referred to as Calories in nutrition.
Recall that 1 pound of body fat is generally estimated to contain a specific amount of stored energy based on scientific research and metabolic studies.
Recognize that the commonly accepted value for the energy stored in 1 pound of body fat is approximately 3,500 kcal.
This value is derived from the fact that fat tissue is not 100% pure fat, but contains water and other components, so the energy content is less than pure fat, which has about 9 kcal per gram.
Use this 3,500 kcal estimate as a standard reference in nutrition and weight management to understand how changes in body fat relate to energy intake and expenditure.
