Fasting is not very effective. You dont lose any fat, but you do lose muscle tissue. your body stores the fat and when you begin to eat again, your body puts that fat on the fat you stored from before. It slows down your metabolism. The best way to lose a drastic amount weight is to divide small amounts of food that you eat. divide the food you eat into 4-5 small portions for each day. also, exercise often(i suggest cardio). It is the best way to lose weight and boost your metabolism.
You cannot lose 5 pounds by fasting for one day.

It is simply not possible to lose 25 pounds per day.
Actually, you won't lose much weight because a five foot, five person who weighs 120 pounds is basically already at it's ideal weight, henceforth, it would be hard for a lean person to lose a lot of weight through fasting. Actually, the more overweight you are, the more weight you lose through fasting and overweight people lose lots of weight through fasting faster as well. :) Hope this helps!!
