I lost 5 stones in a year following the diabetic diet plan: half a plate of vegetables to a quarter plate protein and a quarter plate carbs, trying to keep under 10g of sugars, as little highly processed food and as much fibre as possible. Good luck!

Wow, that's impressive! Well done :) I'm losing around 1kg a month. I'm happy with that... it's something I feel I can sustain until I'm at a healthy weight (not too far to go now) and then maintain at that level.
