Ketogenic Diets Suppress Appetite Despite Weight Loss, Review Finds

Update Date: Nov 23, 2014 10:27 PM EST

Ketogenic diets suppress appetite despite weight loss, a review of evidence suggests. 

Researchers performed a systematic review and meta-analysis of studies that evaluated appetite before and during adherence to very-low-energy diets and ketogenic low-carbohydrate diets. 

Researchers used visual analogue scales to assess appetite in energy balance (before dieting) and while ketosis (during dieting).

They found that individuals on VLEDs had less hunger and greater fullness/satiety. Those on KLCDs had less hunger and reduced desire to eat. Whereas energy restriction typically increases appetite in obese people, individuals on ketogenic diets experienced small absolute reductions in appetite. Individuals on ketogenic diets may feel slightly less hungry, or more full or satisfied, despite weight loss, the press release added. 

"Ketosis appears to provide a plausible explanation for this suppression of appetite," the authors write. "Future studies should investigate the minimum level of ketosis required to achieve appetite suppression during ketogenic weight loss diets, as this could enable inclusion of a greater variety of healthy carbohydrate-containing foods into the diet."

The research was published in the journal Obesity Reviews.
