Is it time to get more vigorous?

Okay so here's what's up: when I was 10 years old, I weighed about 189 lbs, 5'7", and ate McDonald's twice a week. I was extremely fat so I just started doing exercise more frequently and I stopped eating for days sometimes. 4 years later now, I weigh 231 lbs, 5'10", eat healthy everyday, and occasionally reward myself every now and then (get what I mean). Now I know I'm overweight, but I don't look like it and I noticed that when I starved myself I lost fat, but mostly muscle. Ironically, I can bench press 105 lbs but I can't lift 30 lbs on an individual arm. I'm doing my best NOT to use supplements since they're hazardous, but is there a specific routine for me to lose some extra fat while gaining muscle? I have a barely visible 4-pack and I want to lower my abdominal fat. Yes I care about my body, not to only look good but to feel good as well. Any suggestions are welcomed. Thank you.
