The belly of the 13-year-old male is now round and protruding, stretching the fabric of his clothes to their limit. The excess weight has accumulated in layers of soft, jiggling fat that hangs over his waistband. The skin is pale and smooth, lacking any muscle definition or tone. The belly is noticeably larger than the rest of his body, making it difficult for him to move comfortably or bend over. It feels heavy and cumbersome, weighing him down with every step. The belly ripples with every movement, causing ripples of fat to jiggle and bounce. Overall, the belly is a stark and visible reminder of the sudden and drastic weight gain the young boy has experienced.
