dieting advice please!

[Hoggmeister]

thats the first thing i wanted to do mate but everyone else in my house loves junk food so i cant. ive also thought about having my own separate cupboard but then my real issue is craving and giving in to whats in the other cupboards haha. seriously though, i feel like the times come to change because i really dont wanna feel like an unmotivated slob anymore.
