Fat accumulation in muscle (intermuscular, IM) and viscera plays a role in obesity comorbidities. This study examined the impact of Roux‐en‐Y gastric bypass (RYGB) surgery in morbid obesity on changes in regional fat and muscle depots, and these body composition markers were correlated with physical function. Women (n = 18) were assessed prior to (baseline) and 12 months following RYGB for regional body composition and physical function. Weight loss from baseline to 12 months was 33.7 (s.e.m. = 1.7)%; total body fat decreased from 86.8 (s.e.m. = 5.8) to 45.8 (s.e.m. = 3.9) kg during follow‐up. Differential changes in regional body fat were apparent with a volume loss of 58.4% in visceral fat, 19.8% in abdomen IM fat and 50.7% in thigh IM fat. At baseline, abdomen IM fat volume was related to physical function. There was less loss of abdomen IM fat volume than other depots following surgery; furthermore its relationship with physical function is a novel finding.
