Well, the best thing is just to get back to eating right. Â If you are producing morning ketones of 0.5-0.7 or higher (in morning fasted) then you are in nutritional ketosis. As for cheating, the longer you are in ketosis the less the cravings and hunger will be. Â This varies as it depends on how much leptin resistance you have. But just take note of how you feel after cheating and that should help you keep on track.
