I am almost ashamed to post this. My H, who has lost 23 lbs and is 6 lbs from his goal weight, eats 3 bars a day. And has NO stomach trouble unless he eats the ones that are "pure" chocolate. I eat one kind (Atkins Cinnamon Morning Bar) and only if we are out and I will have to go more than 6 hours without eating. I have TOLD him he is learning nothing about good eating habits...he has simply substitued his low carb bars for the fat-free SnackWell's and Pringles he used to consume like air. He just laughs and says I'm learning for him. So it is true that there are some fools out there who can eat these things with NO problem! And lose weight, too!
