Depends on your current weight, and sex. Men get more than women of the same size.
I think a female weighing between 12-14 stone gets 22 points a day, 10-12 stone 20 pts, under 10 stone 18 pts. Someone may clarify (I may be 2 points over?? - not sure). You are allowed to carry points forward - for a party at the weekend, or a meal out etc, but you are encouraged to try and eat all your points for the week - otherwise once you drop the weight, and go onto the reduced points allowance, how would your body know that it's cutting out more?
