Answer:
3,500-calorie rule
Explanation:
The burning of fat provides about 9 kcal/g of fat and one pound of weight equals 454 g, therefore, one pound of fat contains 4086 kcal.
However, the research on the burning of fat indicates that about 3500 kcal are burned as the fat contains only 87% of the lipid which is burned and therefore 87% of 454 will provide 3,500 kcal.
So according to the 3,500 kcal rule, if one pound of fat has to be burned in one week therefore 3500/7 kcal has to burn daily.
Thus, 500 kcal according to the 3,500 kcal rule will be burned.
