When your body starts burning your muffin top and love handles for energy!
Fat adaptation is when your body autopilots on fueling your body with healthy fats over carbs. It generally takes from 30 days to 12 weeks to get fat adapted.
Once you are fat adapted you will notice that you are able to go a longer time without food with sustained high levels of energy and focus. That’s why lots of keto-ers do intermittent fasting after they are fat adapted as it’s easier for them, with the curbed hunger and cravings replaced with high levels of energy.
