I started on 810 as my BMI wasn't high enough. I lost 2kg on average for the first 5weeks. My sorting weight was 11 stones.
So yea def works I am still on the same plan, I fond it helps to have a dinner to look forward to and lets u go out for dinner n have a salad which makes me feel more normal!
Good luck x
