How much weight will i lose on a 500-calorie-a-day diet for 5 days?
There are approximately 3500 calories in one pound (of body fat). If you burn 2000 calories per day, and take in only 500 daily, then you burned 1500 each day. For five days you would burn 7500 calories more than you consumed, and therefore lose about 2.1 pounds. For your stature, however, you burn closer to 1300 calories daily, which means that you should lose about 1.1 pounds in five days. It is likely that you will lose more weight because you will lose a considerable amount of water and other non-caloric mass from the food you are not eating; this weight will return quickly once you return to a normal, healthy eating style. Also, eating too few calories promotes muscle loss, which will lower your metabolism in the long run. It is absolutely vital to maintain strength exercise during this time. This type of diet is not advisable for the average person.
