Quasi-prospective, real-life monitoring of food craving post-bariatric surgery: comparison with overweight and normal weight women.

Abstract

Food cravings are common post-bariatric surgery, suggested as predictors of relapse and weight regain, but relatively unstudied, especially in the longer term. The present study investigated the frequency and nature of food craving experiences after gastric surgery in comparison with non-surgical control participants. Participants were 21 women, 4-38 months post-surgery (mean age = 44 years, 9 following gastric banding, 12 after Roux-en-Y gastric bypass), and two comparison samples of 39 overweight dieters and 33 normal weight non-dieters. They completed a food craving record after every food craving, a daily mood assessment and a food diary over a 7-day period. Over the 299 craving episodes, savoury foods were the most commonly craved (40% of craving events), followed by chocolate (31%). Post-bariatric patients reported more and stronger cravings than normal weight non-dieters but at a similar frequency and strength to overweight dieters. Neither hunger nor negative mood distinguished the food cravings of post-bariatric patients from those of comparison participants, nor did the proportion that led to eating (58%). Food cravings should be anticipated post-bariatric surgery but no more so at 12 months post-surgery than by other overweight or obese individuals. Food cravings are not the product of extreme hunger nor do they have the connection with negative mood seen in disordered eating. In addition, the ability to fulfil cravings by eating the craved food is reduced by the surgery itself, although the duration of surgical restraint is uncertain.
