eat a lot celery all day and drink 3 cups of green tea. You would eat no food to lose weight but skipping out on food would not guarantee losing a pound in one day. In addition, you would add stress to the body by trying to lose that much weight. To give you an idea: one pound of body fat is equal to 3,500 calories and unless you are eating that much a day, you won't lose one pound. You can also lose water weight but when you start eating and drinking regular food, water weight comes right back.
3500 calories equals 1 pound. If you eat 500 calories less a day, you will lose 1 pound a week.
The Atkins diet
If you burn 500 calories more than you eat each day, you would lose approximately one pound per week.
Too many variables. First of all, 1 pound a day, unless you are morbidly obese, is more than is safe. Typically to lose one pound of weight, you have to burn 3500 calories. Most people maintain at half that amount of calories per day, which means it is not possible to lose one pound a day even if you don't eat at all. And intense physical activity is not possible without some calorie intake, that makes it even more difficult. A person doesn't typically gain a pound in a day, so there is no reason to think they should be able to lose a pound in a day.
1 pound 1 pound
Don't eat as much.
dont eat for 2 days and you'll lose 2 pounds!
1/2 a pound i believe
Depending on what you eat in a day, but 20 minutes a day is a good start. If you don't consume too many calories throughout the week, you can lose .2 to 1 pound a week.
