Flatulence?
Why do I always have such a big belly? I don't eat that unhealthily and I exercise occasionally. My sister exercises less and never has a big belly. But I'm not overweight or fat or anything. Why is that? Am I eating something wrong, or should I improve my metabolism?
Sounds like incompatibility.
You can test.
Hello it can be that you always eat until your bauch spat? when do not have to wonder, your metabolism can not affect anyway, which is like it.
