K so I'm asking again idk where my question went but does having low body fat levels make it harder to intermittent fast especially in females? I noticed some days it's hard for me I get dizzy and brain fog and super weak and no energy but other times I feel great. I'm 31 female 5'7" and 90-93lbs and pretty low body fat (muscle definition and vascularity). Couple years ago wen I was heavier and little bit more body fat I could fast upto 20hrs some days but now im lucky if I can make it 16hrs. I'm wondering if it's because I have too low body fat and/or what other factors. I been intermittent fasting for about 4-5 yes already.

I agree with the person who commented above.  You are dangerously thin.  Your weight is NOT healthy.  Why would you even consider fasting at this stage?  Unless you want to kill yourself?

Yes, having very low bodyfat will make intermittent fasting more difficult, even dangerous. In your case, your weight and height suggest that you are anorexic and malnourished. You should not be restricting your food. Please find a medical professional who can help you to eat more and get to a healthy weight.
