I eat AdvantEdge Carb Control bars. I find that they taste the best and come in lots of flavors. My fav is cookies and cream. I also like Lemon Cheesecake. EAS also makes a similiar bar called Myoplex Low Carb, also in good flavors. each bar contains 2-3 grams of carbs technically, but from reading people's posts it seems like there are hidden carbs in many of these bars. I used an online hidden carb calculator and it said there are really 20. But on the flip side, the people who make the bars must know what they're talking about when they say that the ingredients they dont count as carbs have little effect on insulin levels, and therefor aren't counted. I haven't had any problems with them. But I guess you'll have to try it for yourself.
Also, I'm on maintenance, not weight loss. You could try the Atkins bars, they have just as much protein and are suitable for all phases of the diet, including induction. And I bet they taste yummy b/f of the fat content.
I hope that helps!
