I have started using one called Cute - vanilla flavour. It tastes nice actually. I make it with water and it is 130 cals per shake.
I do find them quite filling.
I am combining it with 5:2 - I do one FD a week and then a couple of days where I replace one of two meals with a shake.
Which ones do you use? Do you make them with water or milk? Do you combine their usage with any other weight loss plan?
