Objective To investigate the effects of normal caloric high-protein diet on metabolic parameters and gastrointestinal hormones in patients with obesity or type 2 diabetes mellitus (T2DM). Methods Totally 30 obese subjects (OB group) and 40 obese patients with type 2 diabetes mellitus (T2DM group) received normal caloric high-protein diet for 24 weeks. Then body weight, fat mass, and metabolic parameters were assessed. The serum ghrelin and glucagon-like peptide-1 (GLP-1) levels were also measured at 0 and 2 h after an oral 100 g of steamed bread meal test. Results After 24 weeks, body weight [(78.23±7.51)kg vs (80.83±8.13)kg,P=0.016;(80.45±7.48)kg vs (83.26±9.35)kg,P=0.011], body mass index [(31.03±2.72)kg/m2 vs (32.01±2.95)kg/m2,P=0.033;(32.63±2.81)kg/m2 vs (33.86±3.03)kg/m2,P=0.043], waist circumference [(93.65±6.23)cm vs (97.30±7.81)cm,P=0.041; (97.02±7.43)cm vs (101.87±9.87)cm,P=0.034], fat mass [(30.42±6.18) kg vs (32.47±5.91)kg,P=0.022; (34.23±7.03)kg vs (36.64±6.83)kg,P=0.032], fasting serum insulin [(10.81±3.69)mmol/L vs (13.58±4.86)mmol/L,P=0.012; (9.58±3.51)mmol/L vs (10.82±4.28)mmol/L,P=0.015], HOMA-insulin resistance index [(2.42±0.83) vs (3.16±1.21),P=0.019;(3.15±0.74) vs (4.13±0.67),P=0.024] and triglycerides[(1.24±0.32)mmol/L vs (1.49± 0.52)mmol/L,P=0.046;(1.86±1.05)mmol/L vs (2.46±1.85)mmol/L,P=0.034] were significantly decreased in OB and T2DM groups, respectively, compared with 0 week.Fasting blood glucose(FBG) and glycosylated hemoglobin were also significantly declined in T2DM group [ FBG: (6.73±1.25)mmol/Lvs (8.63±2.81))mmol/L,P=0.010; HbA1c (6.44±0.47)vs (7.38±0.33),P=0.031]. The serum ghrelin and GLP-1 both increased at 0h and 2 h after meal test in OB and T2DM groups [fasting serum ghrelin: (4.98±0.89) μg/L vs (3.95±0.98) μg/L,P=0.021;(4.23±1.67)μg/L vs (3.15±1.01)μg/L,P=0.025; 2 h p
