Human plasma proteome of caloric restriction

We recruited ten normal-weight healthy men using inclusion criteria as previously described (Collet et al 2017). All males were healthy and not obese or overweight (average age: 23.8 years, average BMI (kg/m2): 23.3). Participants at baseline consumed a balanced diet (50% carbohydrate, 30% fat, and 20% protein). During caloric restriction, volunteers consumed 10% of normal energy requirement (226 kcal/d) for two days, again balanced (50% carbohydrate, 30% fat, and 20% protein), with the same macronutrient composition. After caloric restriction, volunteers were offered three substantial ad libitum buffet meals per day (20 MJ = 4,777 kcal) and additional snacks (16 MJ = 3,821 kcal) between meals for 2 days. They were invited to eat freely until comfortably full; food consumption was covertly measured. We collected fasting plasma samples at 0800 AM at baseline, after CR and refeeding (RF).
