Steve,

Cut out all the carbs and sugars for a while and just eat loads of vegetables and fruit, cooked and raw, as much as you like and when you like. Eat a moderate portion of protein every day: fish would be excellent, but a small piece of meat, chicken or cheese would be fine as well.

It's a bit strange to get used to in the beginning as bread is a no no and potatoes, rice and pasta is also "forbidden", so no nice sandwiches, fry-ups, no Sunday roast (only the veg) and no pot noodles! :^O

But you will loose weight if you stick to it and you will actually start to feel better for it, as you will get much more vitamins and minerals this way into your system.

Good luck!
