The authors conducted a meta-analysis of studies that assessed appetite while individuals adhered to a ketogenic low-carbohydrate diet (KLCD) and very-low-energy diet (VLED).
The study concludes that “individuals were less hungry and exhibited greater fullness/satiety while adhering to VLED, and individuals adhering to KLCD were less hungry and had a reduced desire to eat.” Although the changes in appetite were noted to be small, they occurred within the context of energy restriction,which is known to increase appetite in obese people.
In conclusion, there are studies that show the benefit of a KLCD in preventing an increase in appetite, despite weight loss.
