anyone done the 3 day diet

Oliversmummyx

HI, I've been passed on a 3 day diet that claims to lose up to 10lb. Now I'm under no illusions that this won't come back on the minute you eat normally again but I am hearing mixed reviews on this and think as a one off motivater it may help me kick start getting back on track......some people did maintain weight loss
All I'm looking for is feedback in all honesty on if its worth a go.
If you Google 3 day British heart foundation diet youll find the full info
THanks
