There are a few girls on here who do it on here and have lost alot of weight!! So it is totally acheivable. I don't have a calculator to work out points but I'm sure someone on here will soon reply and help you out on that one
If you wanted esourse which is ww online you could also purchase that think it is a Tenner a month or round that..and there's always deals for first few months..gives you your own database really of loads of foods an recipes etc.
Make a food diary on here, pick a weigh in day and keep posting and you will defiantly lose as the girls on here are great for support
