Some people claim that having “cheat days” has helped them break through a weight-loss plateau and that it is beneficial for faster fat loss and morale. But the truth is it varies greatly from individual to individual, and while some people include cheat days to help them stick to their keto diet menu, for others it can have an impact on their determination to succeed. You need to figure out and experience what works for you. After you cheat, you will need a few days to get back into optimal ketosis. You can speed this process up with exogenous ketones.
