Lose fat and eat healthy?

Hi, so I’m a 15yr old girl and I want to start getting more into fitness and health. I don’t exactly know where to start, although I’ve read articles and watched videos on what to do. I have recently go into veganism, only less than a week in but I intend to stay vegan. If anyone else is vegan can you please help with what kind of food I should be eating. I know it should be plant based and/or raw but I don’t know how to put meals together and meal prep. Also I’m not sure how to workout, do I do full body workouts or focus on muscle grouping? I’ve tried doing HIIT but I don’t know if that should be the only workout I do? I want to get rid of my belly fat and flappy arms, I have lost quite a lot of fat, I think, on my body in the last 2 years when I decided to be more healthier. I’m not sure if I should exercise one muscle group or do full body workouts, and I know you can’t spot reduce but I really want to tone my arms and lose belly fat. Not sure if I should start going to the gym too, since lifting weight does tone you. But with my busy homework schedule and school idk, I also my excuses so. Please if anyone can help me as a beginner, I really need to know how to start being a fitter healthier me! Thanks! -sorry for the long message, I really need help!
