What It Takes to Lose a Pound - caloriesperhour.com
| Unit of Weight | Approximate Calories | Approximate Kilojoules |
|---|---|---|
| Pound | 3,500 | 14,644 |
| Kilogram | 7,716 | 32,284 |
A pound of body fat equates to approximately 3500 calories. So if you have a calorie deficit of 500 calories (meaning that you burn 500 calories more than you eat each day) you would lose approximately one pound per week:
500 x 7 = 3,500
It's easy to see that a calorie deficit of 1000 calories would mean that you'd lose approximately two pounds per week. And that's a good number to remember, because two pounds a week is commonly accepted as the maximum rate of weight loss that is healthy.
