Reviewer’s report:  
 
The authors have completed a comprehensive research focusing on the relationship of body 
weight with gastrointestonal motor and sensory function. They assessed postprandial 
gastrointestinal function and sensations of satiation across a wide range o f body weight and after 
weight change. Results indicate that gastric emptying rate is decreased and postprandial 
sensations of satiation are increased in anorexia nervosa patients compared to normal weight and 
overweight patients. These findings support th e authors  hypothesis that the physiological 
response to feeding is more pronounced in individuals with lower body weight and suggest that 
the differences in gastrointestinal motor and sensory function is unlikely to be a primary cause of 
underweight or ob esity. The article is well -organized, it contains all of the necessary 
components. Metodology is clearly explained and article is well -written and easy to understand. 
However, the results would have been even more important if more patients especially obes e, 
were included in the study as well as obese patients who managed to lose >5% of body weight.
