Is there a way to lose the roll of fat on my lower abdomen?

Several ways: 1) diet 2) exercise 3) liposuction 4) tummy tuck (if loose skin and muscles).

Diet and exercise: While diet and exercise are your best bet for losing the excess fat, you may be left with excess skin as well. The skin excess usually requires surgical excision by a plastic surgeon, commonly referred to as a tummy tuck or abdominoplasty.

Yes: Diet, exercise liposuction and/or lipoabdominoplasty (tummy tuck with liposculture).
