Anyone snack on these regularly? They are delicious but there look to be two major downsides - one is the 23g of sugar, the other is the 25% RDV of saturated fat.
However, I notice on the package that it claims to be “low glycemic.” Does that generally mean the sugar in it is not bad for you (in terms of triggering an insulin response etc)? In other words, is 23g of sugar from a low glycemic source no worse for you than 23g of good ol’ complex carbs? Is your body basically going to go and do the same thing with it?
I love them! My wife and I call them “crack bars”. I’m a calorie counter and have come home from long rides and calculated that I’ve got say, 3000 calories that I can eat for the rest of the day. At that point the thought “I could eat 10 crack bars…” HAS popped into my head. 
Seriously though, I think that they are probably somewhere between candy bars and “real food”. They are a nice treat and they’ve got a lot of protien, but there are probably other things I should be eating.
I like to eat one in the morning with my coffee after breakfast. I try to stay away from them after work before I ride because 1 can quickly turn into 3 and that is not a good thing.
Peanut butter is my fav.
I eat 1/2 of one each morning between breakfast/lunch, usually the other half in the late afternoon.
The Choc Chip Mint ones are by far the best thing ever.
I love them too, but don’t eat them anymore.
Unfortunately, most of the protein in them is soy protein. A relatively “cheap” protein and not one that men, particularly older men, should eat in any sort of significant amount. There is enough research out there (and enough sources of higher quality protein) to prove to me, as a man, that soy protein should be avoided because of its effects on testosterone and estrogen levels.
I prefer Snickers. More sugar, it’s true, but less saturated fat.
Low glycemic means that, on the whole, the bar will not trigger as sharp an insulin response as pure glucose (the standard everything is measured against.) There is sugar, but there is also 20g or so of protein, and the combination of the protein and a little fat slows digestion, lowering the insulin response.
A normal cliff bar, I would point out, also has 20 g sugar - but only 10g of protein.
I have a cliff bar before an AM workout; Builders bars make good snacks on busy days.
