not done the official scan bran challenge as such.
but on weeks where ive had scan bran several times i do seem to do well!
im going to be trying to have it at least 4 days this week myself.
i find you need to drink lots for it to work properly though.
Ive done it several times. Its pulled some good losses. I had 5 for lunch as a hex B every day for a week, usually with either laughing cow superlight and tomatoes or beetroot, and ham. If I could do it by making ferrero rochers that would be far more pleasant an experience but the syns would be too high
I did part of the challenge last week, I didnt have them as HEB choices but I did eat at least 2 pieces of it everyday, broken up into a mullerlight yogurt. And one day I did have 5 as HEB.
It helped me lose abit more than usual, usually my losses are 0.5lbs to 1lbs a week and I lost 3lbs.
Be sure to drink plenty of water though if you do it & have a good supply of loo roll in haha! xxx
