1. 1 pound is 3500 calories so 20 pounds is 70,000 calories and over 77 days roughly means about 910 calories per day. So if you diet and eat 500 calories less then average, which is 2000, you would only need to burn another 410 which is like running 3 miles at 6 or 7 miles per hour.
2. you need a calorie deficit of 3500 cals a week in order to lose one pound a week. you do the math.
3. Get real and go for a pound per week.
