Answer:
approximately 350-500 calories per day
Explanation:
It has been shown that obese and lean people's calorie needs are different despite having the same daily activities (for example, sitting and walking). These variations can be associated with different factors including height, weight, sex, age, physical condition, muscle mass, etc. At comparable body weight, lean people need less energy than obese. In this regard, it is important to note that people that have regular exercise routines burn fewer calories when doing the same activity. Moreover, lean people have proportionally more muscle mass than obese people, and thereby they are capable of burning more calories in the same unit of time.
I know it may cause (a) but it gives a higher risk for cancer.
