Hello I’m 15 years old and I weigh 240 pounds. Yes I know very heavy for my age lol but don’t worry that build up over the years and because I’m 5’8 it’s barely noticeable. But looks aren’t what I’m here for, I want to be healthy so I can live a long happy life for the future ahead of me, and I also want to take Karate lessons but because of my weight I am unable to perform many tasks and I can get extremely tired quickly while doing so. So can you guys give me tips on what I should eat and how to exercise please? anything will help thank you!
