Im doing a report on on weight loss. how do u loss 1 lb. a day?

Question

I have been told by a number of experts that a loss in weight of 1 lb/day is too much. They recommend a loss of 1.5 to 2 lbs/week.

thanx

I remember my sisters using "The chemical Diet" actually it is a meal plan, but anyway the 1lb. per day was a claim. sorry it's so vague, it was 29yrs ago. :)
