Good for a few weeks kick start

I did this diet for 7 weeks and lost a stone and 5 pounds but at £50 a week and with functions and events to go to it's not practical long term and tbh it put me off that my consultant although had lost about 6 stone years ago it was clear she was still struggling with the weight and had put some back on and was still doing it herself! I don't want a lifetime of sachets and the meals tasted rank as well as the shakes, the soups porridges and smoothies were nice. It did give me the kick start I needed though to see results fast and I've kept the weight off and I'm now at the gym and eating healthily to lose two more stone.
