Quest.They are gluten free, REALLY low in sugar, high in protein + fiber + most importantly they taste insanely good! I've heard a few bad taste reviews and that's when I suggest buying directly from the Quest website. I've had a couple experiences at GNC or Super Supplements where I've bought a couple boxes and they don't taste as..."fresh." Buy it straight from the source and let your taste buds do the talking.
Lara bars. They have 3-6 all natural ingredients. Yes, higher in sugar but it's from fruit. The downside is that they are tiny + contain nuts (sorry nut allergy folks). The upside is they are gluten free, dairy free, soy free, kosher + vegan.
The Quest Bars I HIGHLY recommend because I eat them + love them, but I'm not the biggest Lara Bar flavor fan. I know a TON of people who go nuts for them, so give 'em a chance before you wave your freak flag (what?).
Clif: Made for mountain men. Or for people who enjoy candy bars disguised as nutrition bars. They do have taste going for them. Back in the day their Chocolate Brownie and Mint Chocolate were my go-to's until I did a sugar detox + realized 1 bar contained 22 grams of sugar!
Luna: Dressed up as a pretty little Luna lady, these wrapper say, "delightful + light." The nutrition facts say, "HA HA GOT YOU!" They aren't as bad as the Clif Bars, with 12 grams of sugar + 9 grams of protein, but what's with all the soy protein? Luna + Clif are sister brands, Luna for the girls + Clif for the boys, at least their marketing is on point.
ThinkThin: Terrible. I ate one of these and felt weird. I was intrigued when I saw 20 grams of protein, 0 sugar and a flavor like Chocolate Fudge, (the same chocolate trick that Clif played on me). When I hear Chocolate anything, I come a runnin'! Except there's 12 grams of sugar alcohols + ingredients listed that you should not be consuming.
