Whats you diet like? If you answer includes more than one daily snack (a slice or two of pizza, an ice cream cone, a fruit rollup for example), cut that to one every other day as a first step. Gradual change helped me get where i needed to be (snacking once a week after a hard week of working out (made me want to go harder because i regretted snacking..tonight was that night lol..so mad i ate the skittles ha).
Start eating healthy, small meals (6ish per day). eggs, milk, chicken, steak, fish, fruit, salad, avocados, oatmel, TONS OF WATER! Tha would be the beginners guide to losing fat, and eating healthy (getting the right amount of vitamins etc).
