Low GL - Cut out all refined carbs and sugar completely, and for the first 30 days alcohol and caffeine. Up your intake of water to 6-8 glasses per day. Change to good carbs ie brown pasta, rice and wholemeal bread. Eat with good protein, lean chicken, turkey or fish. Lots of veg (not potatoes) and salad. Porridge oats or no sugar muesli for breakfast. Two fruit snacks morning and afternoon. Lots of seeds, nuts, oily fish and berries. Use soya milk instead of dairy. Take 100mg vitamin c every day. I used this diet because I was studying to become a Nutritional Therapist and I wanted to see if it worked, it does, my husband lost a stone in a cuple of weeks and I lost 18 pounds in just over a month. There is a book called the Low GL diet by Patrick Holford if you are interested. Good Luck x
