When I was a freshman in highschool I was 6'1 and 170 ( I had no fat in my stomach and had a 6 pack) and that was my ideal weight. I gained more weight up to 230 or maybe 240. I went on a diet and worked out and am now down to 160 and 23 years old and and can see my ribs but I still have a pouch of fat around my belly button that makes me look fat and it leans down over my pants when I sit down. I don't know what to do at this point and need some help.
From both personal experience and things I've read, losing belly fat is more about diet than exercise. Sugar intake, specifically, is something that should be severely limited when trying to lose belly fat. For most adults (myself included), alcohol is a major contributor of sugar intake. The point in my life during which I had the least amount of stomach fat was when I was drinking the least -- 2 times a week, max. That being said, I was also exercising regularly at the time (4-6 times per week), rotating weight lifting and cardio.
