Timing of food intake is associated with weight loss evolution in severe obese patients after bariatric surgery

摘要: Summary Background Recent research has demonstrated a relationship between the timing of food intake and weight loss in humans. However, whether meal can be associated with patients treated bariatric surgery is unknown. Objective To evaluate role food-timing evolution sample 270 that underwent follow-up 6 years. Methods Participants (79% women; age [mean ± SD]: 52 ± 11 years; BMI: 46.5 ± 6.0 kg/m2) were classified according their response patterns after surgery: good weight-loss-responders (67.8%), primarily poor (10.8%) or secondarily (21.4%). Then, they grouped early-eaters late-eaters, to main (before 15:00 h). Obesity biochemical parameters, energy macronutrients intake, expenditure, sleep duration, chronotype studied. Results The percentage late eaters (after 15:00 h) was significantly higher (∼70%) than both (∼42%) (∼37%) (p = 0.011). Consistently, had lunch later as compared (p = 0.034). Age, gender type not determining. Surprisingly, obesity-related variables, pre-surgical total chronotype, calorie distribution, similar among groups. Conclusions Weight effectiveness related meal. Our preliminary results suggest important for regulation eating at right time may relevant factor consider therapy even surgery.
