Hi sczoo90,
I've never done CD before, but have done Lipotrim (3 shakes a day) and was quite hungry. Since doing exante, even though it's still 3 products a day, they do really fill me up (especially after the first few days pass). I get hungry quite quickly, but have found the shakes and bars are substantial. Think the meals help too, as you feel like you're eating something 'normal' and warm...
Hope this helps, let us know what you decide!
