the first two days are easy by day three the problem is mostly boredom and what I've realized is I get a lot of dopamine hits from knowing oh I'm gonna eat like here comes this meal it's gonna be awesome and there's none of that so your day doesn't have those like excitement markers in it so for me the big problem is and then also by day four I do start slowing down even though I'm fully keto adapted I'm posting awesome numbers I'll get into the threes when I'm doing a five day fast so it's like my machineries there I usually do a cycle of keto leading up to a fast so I'm already primed to burn fat so it's not that it's just I do feel less energetic so and I don't know if I just am NOT a great fat burner or if I'm able to I don't use the ketones as official I don't know but by day four I'm like yeah I'm 20% off my normal like I I go go go now it's not like anybody around me notices I just know that it take I have to push my energy out more it's not just naturally there for me
