Hi,
I was in a local playcentre and saw a leaflet for a weight loss company called "Sureslim". They say they tailor diets to suit individual metabolisms and also use blood tests results to get an idea of why weight loss is difficult.
There is nothing on their site indicating costs, but I imagine it costs a fortune and having wasted so much money over the years on different diets, I wouldn't want this to be another one.
Thanks
