Lose a Pound

A pound of human body fat equates to approximately 3,500 calories. So if you have a calorie deficit of 500 calories (meaning that you burn 500 calories more than you take in per day) you would lose approximately one pound per week: 500 x 7 = 3,500cals. There are many ways to decrease your the number of calories you take in. Eat less and eat smarter. The only way to guarantee weight loss, is to eat less and exercise more. That will never fail you.
