I lost 15 kg but belly is same?

People lose fat in different areas -- it's a genetic thing. My midsection was one of the last places I lost weight and the place that held on to fat for the longest.

I feel your pain!!

Where you gain and lose weight is mostly genetically predetermined. Many men carry their weight in their midsection, while many women carry it in their hips and buttocks. I lose weight in my belly quickly and in my thighs very slowly. You can search the forms and see many similar posts from people upset that they've lost weight but not as many inches in the spots they'd like. A common guideline is that you're likely to lose weight first in the last place you put it on, and last in the first place you put it on- so if you first noticed your weight gain in your belly, that's probably the last place it will come off, as well. It may well be that you've actually lost fat in your belly but that your proportions have stayed similar because you lost it in your arms and legs as well, so visually there isn't as much impact. Are your pants fitting differently? Have you gone down a belt notch? Taking measurements and pictures will help you realize when there are changes that aren't obvious from day to day.

You will lose noticeable size in your belly eventually, if you continue to lose weight, but there is nothing short of surgery that can cause spot reduction, unfortunately.

If you have lost it based on the diet plan you posted a few hours ago, it's a good bet your body is tearing down the muscle because it can't use the fat quickly enough to fuel your day.
