As a person that have lost over 40kg's in the past I'd say this is a very true point. I converted from an obese man to a gym body person. The process was long and took a lot of discipline. After years keeping it I'd say the thing I've learned from it is that your diet is around 70% of the effort you have to put in. A lot of people think that lets say bodybuilders are just a product of drugs "oh ye if I take steroids I'll become like him" ... No. Thats definitely not true. While I don't condone the use of any enhancement, I have to admit that being a bodybuilder is a lot more tougher than you think and it requires a lot more discipline on your schedule than you'd think. So yes cut down food and yes exercise a bit... dont just stay inactive, even walking helps ( You'll find out later that the more active you remain by walking etc the easier its going to be when you are older ).
