Accumulation of fat around the abdomen. This form of obesity is most associated with adverse health outcomes.

Abdominal obesity is a physical trait characterised by a horizontal overhang of body fat above the waist, often with little apparent fat on the rest of the body. There is little scientific evidence that beer drinkers are more prone to abdominal obesity, despite it being known colloquially as beer belly, beer gut, or pot belly. One of the few studies conducted on the subject did not find that beer drinkers are more prone to abdominal obesity than nondrinkers or drinkers of wine or spirits Bobak M, Skodova Z, Marmot M.
