Hormonal

Transoral outlet reduction (TORe) delays the postprandial decrease in ghrelin levels by approximately 30 minutes, shifting the nadir from 30 minutes to 60-90 minutes, without significantly altering the total ghrelin exposure (AUC) or correlating with clinical success.

TORe changes *when* you feel hungry after eating, not necessarily *how much* hunger hormone is produced overall. Specifically, it delays the drop in hunger hormones (ghrelin) by about 30 minutes. This might help you feel full a bit longer after a meal, but this specific hormonal change does not predict whether you will successfully lose weight.

ModerateQualifiesMEDIUM confidence
In all analyses, the typical postprandial decrease in ghrelin levels was delayed by 30 minutes... The absence of significant changes in the AUCs of ghrelin levels also corroborates that... ghrelin response is unrelated to CS and no specific baseline behavior or cut-off threshold can be used as a predictor of better response to TORe.

Why this rating

Consistent finding across groups but small sample size and lack of predictive value for weight loss outcomes.
