Adherence to Very-Low-Energy Diets (VLEDs) and Ketogenic Low-Carbohydrate Diets (KLCDs) significantly suppresses subjective hunger and increases fullness/satiety compared to energy balance, effectively preventing the compensatory increase in appetite typically associated with weight loss.
If you are overweight or obese, switching to a Very-Low-Energy Diet (under 800 kcal/day) or a strict Ketogenic Diet (under 50g carbs/day) for 4-12 weeks may help you feel less hungry and more full, contrary to the fear that dieting always makes you hungrier. This appetite suppression is likely driven by ketosis (ketone levels around 0.5 mM).
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.
Why this rating
Based on a systematic review and meta-analysis of 12 studies, though heterogeneity was low and ketone measurement was sparse in some arms.

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
