I think all the ladies have got it spot on.
Drinking lots of water gives me speedier losses, because like SW says, thirst is often confused for hunger, and water fills you up. Just we careful not to drink loads on your weigh in day.
Although I do extra easy, I restrict my intake of carbs (have smaller portions, cut out bread etc) and I find this helps quite a bit.
Also, having a bit of exercise. Doing ten or twenty minutes of manic dancing a day seems to help

. Just stick on a good song and go wild!
I also found eating soup really helps. It can be the super speedy, or anything with lots of veg. I have one that really cleans you out (if you know what i mean...) It's really yummy too.
Chop up 5 spring onions, three celery sticks and 1/2 a bag of celery,
Add to a pan of boiling vegetable stock, add salt and pepper.
Cook this until soft, then add one grated carrot and wait until soft.
Then add one triangle of dairy lea (as part of HEA), and blend again.
Yum!
