Any ideas on how I can lose some weight?

At 15 I ate McDonalds like an animal and never gained a single pound

My diet was mcdonalds and kebabs and I had visible abs.

If I cut back on food it would have done harm

As others have said before, intermittent fasting.
I'd go plant based, obviously cut out bull**** food STANDARD

Stay away from carbs and sugar and sodium, A lot of protein and veggies. Work out with weights and cardio in the same session and box at least 3 times a week.

You prolly burnt it off having to crawl around on all fours with your face in a bowl.

Find your TDEE and just run a small 150-250 caloric deficit — whilst training.
