Popis: BACKGROUND: Several human and rodent studies suggest that in addition to the amount of energy consumed, timing of food intake contributes to body weight regulation. Consuming most energy in the morning has favorable effects on weight loss and weight maintenance. Whether this also affects glucose metabolism and liver fat independently from weight loss is unknown. OBJECTIVE: We hypothesized that during weight loss, consuming most energy in the morning improves insulin sensitivity and reduces hepatic fat content more than consuming most energy in the evening. METHODS: Twenty-three obese insulin resistant men (age 59.9 +/- 7.9 years, body mass index 34.4 +/- 3.8 kg m(-2)) followed a 4-week hypocaloric diet intervention with either 50% of daily energy consumed in the morning (BF group) or evening (D group). Insulin sensitivity, measured with a two-step hyperinsulinemic euglycemic clamp using a glucose tracer, intrahepatic triglycerides (IHTG), measured using magnetic resonance spectroscopy, and resting energy expenditure (REE) were assessed before and after the diet intervention. RESULTS: Meal macronutrient composition and weight loss (6.5 +/- 1.5% vs 6.2 +/- 1.9%, respectively, P = 0.70) did not differ between the BF and D groups. Endogenous glucose production (P
