Is intermittent fasting good for someone 18?

Been intermittent fasting consistently for a month and a half (16-18 Hour Fasts) but I’m not sure if it is safe? My birthday is in a little over a month but should I continue to fast? I’m very active and I’m at a healthy Bodyweight (153 pounds at 5”8) and I’m also very active. I go to the gym, 5-7 mile runs 5-6 days a week, and a lot of walking (currently a college student). I’m also under 18.
