We retrospectively assessed the effect of total protein intake (TPro) during exercise training on body composition (BC) and indices of metabolic syndrome (MS) in overweight/obese middle‐aged adults. 100 men/women performed aerobic/resistance exercise training 3x/wk and consumed unrestricted diets along with 200 kcal supplements (0, 10, 20 or 30 g whey protein) 2x/d for 36 wk. Subjects were clustered into 3 TPro groups: < 1.0 (n=36 low protein, LP), 蠅1.0 ‐ <1.2 (n=25 moderate protein, MP), and 蠅 1.2 (n=39 high protein, HP) g•kg ‐1 •d ‐1 . TPro was inversely associated with changes in body mass (BM), BMI, fat mass (FM), % FM, and lean mass (LM), and positively associated with change in % LM (multiple regression). Similar results were observed for regional (android and gynoid) BC changes. TPro was not associated with changes in MS indices: waist circumference, blood pressure, and serum glucose, triacylglycerol, and HDL. Based on cluster analyses, TPro influenced changes in BC. The responses in the LP, MP, and HP groups were as follows: (means with superscripts without a common letter differ, p<0.05) BM (1.9±0.6 a , 0.1±0.7 ab , ‐0.3±0.5 b kg ), FM (0.7±0.5 a , ‐1.3±0.6 b , ‐1.1±0.4 b kg ), % FM (‐0.2±0.3 a , ‐1.7±0.4 b , ‐1.2±0.3 ab %), and % LM (0.2±0.3 a , 1.7±0.4 b , 1.2±0.3 ab % ). Comparable results were observed in the android region, but TPro did not influence responses in the gynoid region. Intake of LP, MP, or HP did not influence the responses of MS indices. These results suggest that the beneficial impact of higher TPro on weight control and adiposity do not extend to indices of metabolic health in middle‐aged overweight /obese adults.
