This is why stating -500 calories is completely wrong and far to vague.
Read carefully, A deficient goal of -500 a dayshould be made from exercise and calorie restriction. Simply going off of someones BMR and subtracting 500 calories while adding to that exercise and not bothering with calculating lifestyle activity and so on. Would lead to a far to great calorie restriction.
500x7 days equals about 3,500calories, or the amount of calories in one pound of fat. The problem here, is its are only taking into consideration his BMR and only calculating the deficient through calorie restriction, not the other variables. Well, what if his BMR (calorie needs as if in coma) was 3,000calories and through diet alone he cut off 500calories a day. Ok so that puts him at about one pound per week(5x7). HOWEVER, now what about his heightened calorie need from his job and everyday life in general? Well his deficient just went up to 1,000 (assuming he has a low intense lifestyle) calories a day. Now he is at a Along with his BMR he needs to calculate in his daily needs through everyday life. The deficient should be made from exercise and calorie restriction. Simply going off of someones BMR and subtracting 500 calories while adding to that exercise. Would lead to a far to great calorie restriction.

HOWEVER, now what about his heightened calorie need from his job and everyday life in general? Well his deficient just went up to 1,000 (assuming he has a very intense lifestyle) calories a day. Now he is at a 7,000 calorie deficient a week. BUT wait there's more, lets factor in his new exercise regimen. So another 300calories a day from exercise. That puts him at a daily deficient of 1,300 calories! That mean his weekly deficient is now around 9,100caloires, assuming things remained stable 7days a week.!
Now, understand what I'm saying here? Simply saying eat 500calories less a day while exercising more and maintaining a normal active life is not quite optimal. And will lead to a deficient that is far to large for anyone. deficient a week. BUT wait there's more, lets factor in his new exercise regimen. So another 300calories a day from exercise.
