Dietary Habits and Belly Fat. While eating too much of any food can cause weight gain, some foods are more likely to lead to the accumulation of belly fat than others. If you have a serious soda habit, you're more likely to have a large, hard belly.
Separation of the abdominal muscles during pregnancy. During pregnancy, the growing uterus stretches the muscles in the abdomen. This can cause the two large parallel bands of muscles that meet in the middle of the abdomen to separate â a condition called diastasis recti or diastasis recti abdominis.iastasis recti might cause a bulge in the middle of the abdomen where the two muscles separate. The condition might be noticeable only when the abdominal muscles are tense, such as during coughing.
