Question 256080: a doctor places an overweight man on a strict diet to reduce his weight from 200 kg to 80 kg . if he loses 3% of his weight every week how long will it take him to reach his target weight.? Answer by solver91311(24713) (Show Source):
Well, that depends. Do you mean that the patient is supposed to lose 3% of 200kg (i.e. 6kg) each week, or is he supposed to lose 3% of the current weight each week?
weeks.
Or
weeks
Except that neither answer is correct in practical terms. In order to lose 1kg per week, a person needs to have a caloric deficit of about 1100 calories PER DAY. So 6 kg per week means a 6600 calorie PER DAY deficit, i.e. a combination of eating less and exercising more. Even at 440 lbs, at a 6600 calorie per day deficit, the poor schmuck would probably die from malnourishment and dehydration within 2 or three weeks. 0.5% per week, at least at the outset, is more like what would be a safe rate of weight loss.
