Why is having a big belly so detrimental to one’s health?

Unless u r pregnant. If your belly is big b/c you're pregnant, then it's not considered detrimental. However, belly fat is different from fat elsewhere in the body in that it's associated w/greater risk of heart disease, diabetes, stroke, death, etc. If your body shape is more like an apple w/typical beer belly, that's bad b/c all fat is inside surrounding your organs. It's ok if u r pear shaped w/fat on ur behind.
