Answer by NIB (42). One pound of fat has 3500 calories. So in order to lose 1 pound you need to burn an extra 3500 calories or receive 3500 less calories, though there are other factors too. For example you can lose 1 pound by receiving 500 less calories per day for 7 days. add a comment.

The first part of the calorie formula is the assertion that one pound of fat contains 3,500 calories. You will struggle to find anyone who can demonstrate the precise calculation behind this, so I'll offer this as a suggestion: 1) One pound equals 454 grams (decimal places aside, this is a fact);

According to Hall, in the first year of a new weight-loss program, most overweight people will lose about half the weight that the 3,500-calories rule predicts. In other words, over 12 months, the new rule is 7,000 calories = one pound.

One of the most commonly held diet myths is To lose one pound of fat you need to create a deficit of 3,500 calories. This is wrong at every level. First of all, one pound does not equal 3,500 calories, as we will show below. You will see this formula in government literature, in just about every diet book, in private health booklets and all over the internet. The next time you see it, or hear it, ask where it comes from. You will not get an answer.

Using the Pennington online calculator, a 200-lb man aged 35 who cut 500 kcal/day from his diet would be expected to lose 23 lbs in one year vs 23 lbs in four months in accordance with the 3,500-calorie-per-pound rule.

It's been estimated that the 3,500-calorie rule is cited in more than 35,000 educational weight-loss sites.1 In September, the Journal of the American Medical Association published a patient handout titled Healthy Weight Loss, in which the first sentence states, A total of 3,500 calories equals 1 pound of body fat.

If we think one pound equals 3,500 calories and in fact one pound equals 2,843 calories, over a year, 657 ‘extra’ calories a day, simply from the formula ‘being wrong’, would add up to 239,805 extra calories and this, divided by 2,843 gives 84 pounds, or six stone.

Conventional Weight-Loss Wisdom. Ask any dietitian and he or she likely will say that cutting food intake by 3,500 calories results in a 1-lb loss. Cut 500 calories per day and that's 1 lb per week. Over the course of one year, that would equal 52 lbs.

This means if you decrease (or increase) your intake by 500 calories daily, you will lose (or gain) 1 pound per week.2 Undoubtedly, the 3,500-calorie dogma still is being taught even though it's been shown that it simply doesn't work this way.
