Whats up I have been a big person all my life I came from a tall and big family. So what I want to say is that how u can start off doing is driking lost of water and as many times u go to the bath room u are cleaning your body out and u are losing the weight like that and to help start running, find a time thats good for u and fun at least 2or3 blocks and stop then drink water.Water,Water,Water,Water. Try it. It just might save your life
