Intermittent fasting can induce a temporary state of ketosis where the body is unsure whether to burn carbs or fat, leading to low energy and lethargy.

“And so, intermittent fasting for me is difficult in that it kinda puts me in this temporary state, especially if I do it two days in a row. And so, my body is not in full on ketosis mode, but it's not, you know... So it's... I don't like it.”

“it throws you into a kind of a temporary ketosis really quickly, but it's a bad place to be. Because I feel like your body is not sure what it should be doing. It doesn't know whether it should be like burning carbs or fat, right? And so, in ketosis, like they talk about this keto flu that's during the induction phase, like the first few days are hell. Because you're just like...you're not in full on ketosis, you get this kind of sick feeling where you don't have enough energy, you just wanna lay around a lot.”
