Does anyone else feel weak mentally and physically when they have low body fat?

I realized when my body is lower I don't produce that much testosterone. I feel weaker. I'm more tired, agitated and anxious.

Yeah I look better, but my physical strength declined, i can't concentrate as much and my willpower is shot.

Even when I have days off and I eat a shitload. I don't feel the same as when I had a gut.

I'm trying to be alpha af here but my hormones don't feel the same. I'm trying to have the right mindset but my body isn't letting me.
