I find the bars make me feel a bit hungry , but dont try taking them off me I love em!! what I dont do is have them for brekkie, I have a shake in 2 halves at work and sometimes a half packet of soup, and then I have my bar as a treat when I get home, first half about 5pm and then if I can hold out then the over half at 6-7 oclock, with half packets of shake of soup through out the evening, it works for me. I think I am very sensitive to carbs as the only time I had a bar for breakfast I was hungry all day, and not very happy. I now find a bar of an evening is perfect!
