Health food you eat ?

I caught up with my friend having not seen her for quite some time. I have to be honest and say that she was on the heavy side but I was really surprised when she pitched up at the cafe bar where we had arranged to meet. I nearly didn't recognise her as she had shed a load of weight and looked really slim. She told me about her weight loss and nutrition program which she has found really easy to follow and said she has told a few of her friends who have all been singing her praises for introducing them to it. I know she's tried other dieting fads before but had no joy and from the way she looked and her new found confidence in herself, I'd say that this program must be fairly good.
