5. Appetite Suppression
Many people report decreased hunger while following a ketogenic diet.
The reasons why this happens are still being investigated.
However, it’s been suggested the hunger reduction may be due to an increased protein and vegetable intake, along with alterations to your body’s hunger hormones (12).
The ketones themselves may also affect the brain to reduce appetite (13).
Bottom Line: A ketogenic diet can significantly reduce appetite and hunger. If you feel full and don’t need to eat as often as before, then you may be in ketosis.
