Losing weight was easy for me and all I did was giving up eating sugar at the amount I ate it before. I also did no more exercise of any sort than previously.
However, I've never been a glutton.
I repeat- I did NOT eat less. I just gave up sugary drinks, chocolate, cakes, sweet biscuits, the cream buns, etc and things like pizzas and white bread which are easily converted to sugar in the body.
