40 days: Here is the math. There are 3500 calories in a pound. Take your current weight and add a 0. Say 150 lbs add 0 get 1500. This is the amount of calories you need daily to maintain your weight. So to add a pound a day you must eat 1500 + 3500 calories to gain a pound a day. So if you can eat 5000 calories every day you would gain 40 lbs. over 40 days if you weigh 150 lbs. Happy Eating..
