Descrição: dc.descriptionPurpose: Obstructive Sleep Apnea (OSA) is closely associated with obesity. Weight loss ameliorates OSA and its associated metabolic disorders. A high protein intake may improve weight loss through increased energy expenditure, and fat-free mass maintenance during weight loss. Objectives: To evaluate the effects of a low-energy, high-protein diet on OSA severity and metabolic parameters in obese men. Methods: Forty-five OSA obese (BMI ≥ 30 kg/m2) males were included in this randomized study and submitted to nocturnal polysomnography, body composition measured by plethysmography, biochemical analyses of blood glucose, insulin and lipids, and food intake evaluations before and after one month of a low-energy diet. Diets were designed to create a 30% deficit in total energy expenditure with 1.6 g of protein/kg/day (High Protein group - HP) or 0.8 g of protein/kg/day (Low Protein group - LP). Results: Only a time effect of the intervention was observed in body mass (−3.7 ± 2.0% for the LP group and −4.0 ± 1.5% for the HP group; p < 0.001), Body Mass Index (p < 0.001), fat mass in kg (p < 0.01) and fat-free mass in kg (p < 0.01). Significant improvements in Apnea Hypopnea Index were observed in both groups (54.0 ± 25.0 to 33.7 ± 31.7 in LP group; 39.7 ± 24.3 to 21.4 ± 25.9 in HP group; p = 0.06). Improvements of 38% and 46% in the Apnea-Hypopnea Index were observed in the LP and HP groups, respectively. Both interventions provided equivalent metabolic benefits as reductions in glucose (p < 0.001), insulin (p < 0.001), HOMA-IR (p = 0.005), triglycerides (p = 0.002), and in total cholesterol (p = 0.004). Conclusion: One month of a low-energy diet resulted in significant improvements in OSA severity in obese men. Increased protein intake during a short period of low-energy diet had no further beneficial effects on OSA severity or biochemical parameters than a standard protein diet.
