I was a religious breakfast eater. Would often wake up because I was hungry. The first few weeks of IF was rough, but the hunger eventually passed. My energy levels also dipped, but then went way up. I try to do all my deep work and exercise before my first feeding of the day because of how sharp I feel.
3ish years in I feel great, and routinely get comments how 'in shape' I look. I also try to weight train every day and train BJJ a few times/week.
Other things I've learned personally is if I eat poorly the night before (lots of sweets or something), I am more likely to feel a bit of hunger the next morning. Normally I don't really feel hungry though, and if I'm busy I can go right through lunch without noticing.
