I inadvertently started fasting during college due to my class schedule, living off campus, and not being able to afford eating out. I'm now at a point in my life where my schedule is more flexible, I'm not spending as much time commuting, and I can afford to eat out if I choose to, but I've continued to maintain a one meal a day lifestyle. I don't feel the sensation of hunger anymore though I still have an appetite. My coworkers get noticeably anxious and antsy if they don't have their lunch by 11 AM while hunger no longer affects my ability to concentrate. I've also been able to maintain a healthy BMI as I age; I'm neither overweight or underweight.
I will say that when I was younger I often wanted a bodybuilder physique, but I didn't have the discipline to eat enough to support proper muscle growth. Now I'm just glad I'm not going the seemingly inevitable route of becoming an overweight middle-aged office worker that morphs into their chair.
Edit: To be clear, I still go to the gym regularly to lift weights and do cardio even with fasting, but I never have and never will compete in any bodybuilding competitions (which I'm OK with).
