Gosh that was quick!
I suppose then I am better to just stick to trying to keep at the exact 20 points. Eating within a range sounds more flexible. I often do end up with 20-24 anyway but then i feel ive gone over and with you plan i would still be OK. A while back I tried to hurry things alond by eating only about 18 and you know what. After a week I stopped losing altogether. It mucked it all up and then I got too hungry and threw the whole thing in and now I am starting over again, again
Im onto my 2nd week now and have lost 2kg.
