@gamesbx You're still young, so you can do it if you really want to. It's going to take some time, but the best time to start is now.
Arnold Schwarzenegger said (I think it was in the movie "pumping iron"): decide what your goal is. Then for everything you do, every decision about what to eat or whether to exercise, ask yourself: will this get me closer to my goal? Then do whatever will get your closer to your goal.
A few years ago I got a gym membership (2 years prepaid through Costco). I committed to going to the gym every day for the first year (then Covid hit, etc.) I never had to think about whether to go to the gym that day, or what excuse I should use to put it off. I had to go every day. No reasons, no excuses, nothing to thing about. Just go. One day there was ice on the roads, and I got the gym and found it was closed. Still, it wasn't me who was making excuses that day.
Diet is the most important part for weight loss. It's a lot easier to avoid 1000 calories of snacks, than to burn 1000 calories exercising. That's 80 minutes of fairly intense cycling, but I could eat that much food in a few minutes.
Use a calorie-counting app. It's a bit a hassle, but if you do it for 2 months, you'll get a good feel for what has a lot of calories and what doesn't.
The best start is to stop eating/drinking anything that has added sugar. None of those things are good for you.
If you don't want to go to the gym (I hate gyms), start with walking 30 minutes a day, then 60 minutes, maybe more. Running can be hard on your knees and feet, but walking is a lot easier, it just takes more time. You can buy a kettlebell and some dumbbells and exercise at home.
You now have a new mission in life.
