Hi,
I am also trying to loose 10 lbs

I have been on the glycymic index diet for a week now and have lost 2 lbs (average weight lose on this diet is 2lbs a week) so you should be able to loose 10 lbs in 5 weeks maybe 4. It does consist of alot of salads and fruit. But I seem to be able to tolerate everything since I started a new med called
Buscapan I am week 3 and have never felt better, no attacks and am very regular. There are no side effects that I experience.
Anyway I joined online at ediets.com $17.00 \mth they prepare your meal plan for aweek comes with recipes and shopping lists. Its very hard to loose weight when you have IBS, I have tried lots of things, and have finally found something that works for me.
Good Luck
