I'm looking into low calorie meal replacement diets to address my alarming weight gain over the past few years. I need to lose a lot of weight as I'm roughly 15st and under 5ft tall. I want to prevent the onset of arthritis and diabetes that's likely to come and I've had no success with traditional diets and exercise as I also have PCOS, which makes weight loss harder but not impossible. I would like to date and have a family some day and the weight and fitness level I am now makes that basically impossible.
Any advice, hints and tips would be fantastic.
