How to reduce belly size in short period?

If only that easy...: Body sculpting sounds promising (& there are gimmicks & diets that promise you their products can do this), but the only way to effectively spot-reduce unwanted tissue is to surgically remove it. The "pear" body type preferentially stores fat around the hips; "apples" store it around their waist. Of course, exercise & healthy eating are key to long-term maintenance of the body appearance you seek.
