Starting With Weightlifting

This week i start Weightlifting for baseball and i also have show choir bowling and pep band in the way so is their any advice out their to maybe get a kick start on this and start losing. but my first priority is bowling because we have a strike system get 3 and your out so that is one, two is show choir that is season long and for competition, three baseball we have tryouts soon in early march, and finally pep band even though is is mandatory to do if you signed up witch i did but i worked it out with the directors to break even with practices. Please leave any tips to help even if it is like eat this instead of this or do this instead of playing on the computer or something, try not to go in the kitchen it is a war zone for weight losers anything will help. thanks. I am 261lbs, 15 years old, and 5' 8.5".
