Probably if they are really overweight, or if they starve themselves. Not usually a good idea.
You might want to rephrase your question, but to lose one pound, you must lose one pound. Every 3500 calories is one pound.
I did 20 minutes on my treadmill , 4 days a week, and lost about one pound a week.
There are many people that can lose a pound of weight every day but it is not healthy to do so. Losing one to two pounds a week is a good amount to lose.
1 Pound
no you cant you can only lose it in days,weeks,or even months.
If you want to lose a pound of fat and not water weight, it takes 3500 calories. So it takes 7 days of having a 500 calorie deficit to lose a pound of fat.
About a pound every 6 days. Just by cutting calories. A pound of body fat equals 3500 calories. 3500 divided by 6 equals 5.83333. I rounded it up to 6 days. If you're working out, etc., then expect to lose more. Hope this helps!
Three days
Don't eat as much.
That would be about 1 pound every 2 to 3 days. It is possible, but it would require a lot of exercise and dieting.
1 pound 1 pound
It vaires per person and based on their own individual habits. If is it just an extreme diet, they may lose a pound every week or two. If they are intensely exercising and really restricting their food intake they may be able to lose a pound or two every week.
