简要总结
This study is aimed at assessing how Roux-en-Y gastric bypass (RYGP) impacts on energy and nutrients' intake, energy expenditure, and nutritional status in obese patients. It will try quantitate energy and protein balance after RYGP, and to identify how RYGP effects the intake of various common dietary protein sources 16 female patients with BMI > 40 kg/m2 and on a waiting list for bariatric surgery will be included. The following measurements will be performed before, and 1, 3, 6, 12, and 36 months after RYGP
- body weight
- body composition (bio impedancemetry)
- basal metabolic rate (open circuit indirect calorimetry)
- 24-hour urinary urea excretion
- fasting blood chemistry
- energy and macronutrient's intake (3-day dietary recall)

结局指标
主要结局
changes in daily dietary protein intake
时间窗: measurements obtained baseline , and 1,3, 6, 12, 36 months after surgery
changes in 24-hour protein intake will be evaluated by 7-day food diary; portion size will be assessed with the use of photographs from the SU.VI.MAX study
次要结局
- changes in total energy intake(measurements obtained baseline , and 1,3, 6, 12, 36 months after surgery)
- changes in basal metabolic rate(measurements obtained baseline , and 3, 6, 12, 36 months after surgery)
