# Unexpected boost and loss of appetite
Both boost and loss of appetite happen during the process of ketosis as it is a metabolic process. When you enter ketosis, your body gives you signals about your hunger due to fewer carbs consumption. Your stomach and liver give signals to brain constantly, so the brain avoids about feeling of fullness. After some time, body becomes addicted of using fats and not feeling hungry anymore. This is called an unexpected increase and loss of appetite.
