How can you lose 20 pounds of stomach fat in one month?
There is no way to reduce fat from any one area of the body
alone. This type of "Spot Reduction" is a myth. Your body loses fat
from all areas of the body equally.
Doing abdominal exercises will firm and tone up the muscle under
the fat, but has no direct effect on the fat itself.
General weight loss is the ONLY way to lose weight from any area
of the body.
