I have been having Slim Fast High Protein shakes, 2 a day, sugar free jello and fat free/sugar free pudding plus chicken or beef broth...I find that if I have a shake in the am them sip water religiously until lunch, broth and a pudding, water, then shake and jello in the evening, I am pretty satisfied, yesterday I was a bit hungry, but I only had one shake. Atkins shakes didn't seem to satisfy the hunger as well.
