I did diet as I am lazy.
I went extreme for a while with this Keto diet, Not for everyone but I did it for a while it broke all my habits of eating stuff full of sugar.I used to down cans of coke like they were going out of business so i removed that and stuff like crisps. I am not much of a drinker so that wasn't a factor.
I lost 30lbs and went down to 12 stone, but i just eat whatever now i keep an eye if it goes over a certain amount.
on the other hand i had to buy completely new clothes.
