Pack in the pounds!

people say i dont need to lose weight, but on the inside i feel asif ive let my go with eating a load of crap. i feel like the jeans i wear belong to someone else, they're gettng far too tight for me and i find myself ssqquueeeezziinng into my clothes, but ive checked my BMI and i seem to e an idea weight, does that mean im not entitled to lose a stone atleast?
