Comments: Unlike many protein bars, the thinkThin Chunky Peanut Butter bar had a relatively soft and somewhat grainy texture, with just a hint of crunchiness. “Chunky” is a misnomer, as the texture was even throughout – there were no chunks of peanut at all.

The bar was sweet, but had an odd, un-peanutty taste, almost like eating a chocolate-covered Frito bar. It wasn’t bad, but not what I expected.

One nice thing about this bar was that good-quality ingredients were used: the protein blend is solid; real peanuts were used, and there were a minimum of additives. The bars are also competitively priced: purchased from the company web site, a box of 10 sells for $17 (not including shipping and handling).

I found it to be less than satisfying, however. I ate one as a pre-dinner snack, and found that it didn’t do much to satisfy – much less suppress – my appetite. In my opinion, it could work as a “value added fix” to satisfy a craving for something sweet, but not as an actual meal replacement.

People with “special dietary needs” should pay close attention to the ingredients, too: while these bars would be suitable for diabetics (low glycemic index) and people on gluten-free diets; they would not be appropriate for those with dairy, soy or nut allergies. Moderation is also advisable, as sugar alcohols can cause bloating and/or diarrhea when eaten in excess.

Here’s how I rate this product (out of 5 stars):

Taste:2.5 out of 5 stars (2.5 / 5)
Quality:4.5 out of 5 stars (4.5 / 5)
Efficacy:2 out of 5 stars (2.0 / 5)
Value:3.5 out of 5 stars (3.5 / 5)
Average:3.1 out of 5 stars (3.1 / 5)

  1. I love Think Thin bars, particularly the Chunky Peanut Butter (and yes, I know it’s not really chunky). They are my go-to bar when I’m out and about and can’t stop for food but it’s really time for the next meal. And yes, at 6 small meals a day, which is what I eat, one of these bars is just fine for one of those meals. I love the quality of the ingredients. Don’t like all the other flavors quite as much, though Dark Chocolate is pretty good.
