Lose 50 Pounds a Year

"The basic rule of weight loss is that you take in fewer calories than you burn -- and if you want to turn a positive calorie balance into the calorie deficit you need to lose weight, just make some smart choices in what you eat and drink, and how you burn calories.



The second rule of weight loss is that if you take in 3,500 fewer calories than you burn, you'll (generally) lose a pound of fat. So if you can have a calorie deficit of 500 calories a day, you'll burn a pound of fat a week (7 times 500 is 3,500), which is about 50 pounds a year."
