Think Thin Bars, manufactured by thinkThin, are marketed as a protein bar that promotes weight loss and increases energy.

Think Thin Bars do not really stand out from the rest of the supposed snack and meal replacing weight loss products available today. Think Thin Bars may not be an effective weight loss product because there does not seem to be any proven appetite suppressants or fat burners in it so those seeking a weight loss supplement with the ability to suppress the appetite and burn fat may want to research other products that are intended for appetite suppression and fat burning. Those seeking weight loss may also benefit from developing a healthy diet and exercise program that suits them and their lifestyle. Users will need to assess their health and fitness goals and decide if using Think Thin Bars is right for them.

    I think these bars are super yummy. I don’t feel guilty eating them when I want something chocolaty to sink my teeth into. Afterwards, I don’t feel hungry for hours. They make a great snack to keep in your desk at the office!

    One word should cause you NOT to eat this product: HYDROGENATED


  • 3

    I love these. They just came out with the crunchy nuts version. They keep me full for a few hours and I love the texture of biting into them. Kinda like a candy bar texture. My fav is the Chocolate fudge.



    Are Think Thin Bars safe for teenagers?


  • 4

    Yes, they taste great. There is just one big problem that I have with them. They bloat me and make me pass some nasty gasses. I mean it is annoying. I don’t want to fart all day long and stink up the places. And that’s how bad they are, especially the Think Thin + Fiber. Stay away, or you’re gonna blow up and smell!

    I bought the brownie crunch Think Thin bar on the fly because I needed a protein bar. My intention was not for weight loss. I also liked the fact that it was gluten free. It was tasty. I am lactose intolerant but this bar did not give me any problems. I would buy it again.


  • 6

    the no sugar is impressive, but there is only two grand of fiber? and they taste nastyand have more calorie than my diet allows. I eat half a/ raw fruit or veggie. I use them and slim fast, and special k, and kind bars.i have lost nine pounds in three week. that’s as a meal replace in the slim fast plan.

    what about the alcohol sugars?? what on earth are they? very confusing.

    YUM!!! The Creamy Peanut Butter tastes delicious!! Eating one as I write this… First time trying, so I don’t know if there are any weight loss-benefits yet. All I know, is it tastes batter than any bar I’ve ever tried, no sugar, and I’m already full and not even through the whole bar yet. I’m excited to try other bars.

    I have been eating a think thin bar for breakfast everyday for the past couple of years. The creamy peanut butter is my favorite and it satisfies me for 3-4 hours… I have always eaten a low glycemic diet, exercised daily, and have maintained my weight with the help of these bars. Sometimes I even have one before i go to bed if I’m craving something sweet! I order in bulk through the company every few months. I love these bars as well as Quest bars and Kind bars.

    “Think Thin Bars do not really stand out from the rest of the supposed snack and meal replacing weight loss products available today.”

    I don’t understand how you can make that assertion. Think Thin bars do not have any sugar in them whatsoever. This is a huge difference from most snack and meal weight loss products. Especially when they are compared with other protein bars, which sometimes have up to 25-30 grams of sugar in a single bar.

    I agree with other users who praised these bars for their ingredient list and flavor as well. They also have significantly higher amount of protein than the average protein bar (two time as much as the typical protein bar).


  • 11

    LOVE these bars. So hard to find anything without sugar and they are both delicious and satisfying. I’ve been enjoying the chocolate fudge and have no complaints. They keep me full for hours and are supporting my weight loss goals. Anxious to try the other flavors.


  • 12

    I bought these bars on a lark. I have eaten just about every protein bar out there. These bars were so good, that I looked them up to buy in bulk. They were a great snack for me because I’m on the road alot and most stores carry junk bars loaded with sugar. I wanted a good balance. These buys surprised me and the taste was good compared to other protein bars. I would like to see more of a whey protein, but the soy will be o.k.


  • 13

    A girlfriend of mine told me that these bars caused her excessive flatulence. I didn’t believe her till I tried one…



    I thought it was just me! I was passing the GROSSEST gas and could not stop pooping! Ugh.



    It’s the sugar alcohols that cause the gastric issues, the gas and diarrhea.


  • 14

    Love these bars! I have to eat low glycemic, and it’s hard to find something for on the go. I eat half for a snack and the other half right before working out. They hold me over and help keep my blood sugar on target.


  • 15

    Does it actually help you loose weight?



    Not sure if they help you lose weight, I eat them a lot though.


  • 16

    Those of you that think it tastes gross, I’m going to say you consume a lot of sugar and/or lots of processed foods. Take refined sugar out of your diet completely and you’ll start to taste food again, for real. These bars taste great and are very sweet tasting to me, and appreciate the no sugar added. They are good for protein which helps supress appetite, but not recommended after a heavy weight lifting session at the gym. You shouldn’t have fat right after you lift. Give it a half hour/hour and then yes, fat is good for you. Well, you know what I mean – good fats, in moderation and in balance with carbs & proteins.



    I totally agree with you!! I just ate my second bar just as I was reading your post! I’m on that time of the month and I was craving chocolate so bad.. Bought a couple bars from different brands and this one is by far the best when it comes to flavor and sweetness I don’t consume sugar on a regular basis so I found them very sweet!! Perfect to trick my mind :-) .. I don’t know if I would eat them on a regular basis because they do have a lot of calories.. But in special occassions I would totally eat them.

    Maybe it was that scarring week I spent at the Optimum Health Institute eating sprouts and drinking wheatgrass juice, but I love the taste of Think Thin bars. Aside from the “Natural Flavors” (which is who knows what), I am impressed with the ingredient list and the balance of macronutrients (proteins, fats, and carbs). Potassium iodide is even included, which is wonderful for our iodine-deficient society, scourged with high levels of subfunctioning thyroids and thyroid syndromes. That may be one reasons why these bars are promoted as weight loss and energy bars because the thyroid needs iodine to manufacture its hormones, which regulate the metabolism. Sugar alcohols, like Xylitol, have actually been touted as a form of tooth decay prevention. They are not tolerated well by some people, but for others the lower insulin spike it produces is very desirable. We need some carbs/sugars with our protein so that the body will release insulin and drive the protein into the muscle cells. As far as flavors go, I’m partial to peanut butter, not a big chocolate fan. The lemon ones are pretty good, too.

    my wife and I really like these bars. they are low carb, high protein and low glycemic index so does not spike the blood sugar. These are not candy bars and make a great replacement. We use them as a snack or meal replacement (we try to eat small amounts, 6-7 times a day). The best part about these is that they do not make you crave for more. I eat one and do not need more to eat for another 2-3 hours.
    chocolate mudslide, crunch and chunky peanut butter are the 3 best flavors, though i do like the dark chocolate also (but they have caffeine and I drink enough of that).


  • 19

    im eating the chocolate mudslide right now, and it tastes absolutely disgusting.
    pretty much killed my appetite though.

    how many net carbs are there in the Think Thin bars?


  • 21

    I’m confused about the Think Thin bars, althought it states NO SUGAR – what about the SUGAR ALCOHOL that has 16g, sugar is sugar regardless of how is labeled. Also have you noticed the CARBS ???????

    I bought this and am going to return………



    I have gestational diabetes. Per my dietary instructions I can have a 2 carb snack which is 30g of carbohydrates. The bars I have, lemon cream pie flavor and chocolate only have 20g of carbs, that is not bad at all. I am not sure what the beef is, but the 15g of protien is very good compared to other bars with less than 9 grams. The price is good too. I have not had any problems using these as a snack. They do not affect my blood sugar level and I highly recommend them.


  • 22

    I agree with Dawn about the taste, the number of protein grams, and the A+ rating. I’ve had the chunky peanut butter bars, the white chocolate raspberry bites, and the lemon bars, and I liked all three. Considering that 20 grams of protein and the terrific low-GI effect, I think they taste good .. good enough to satisfy my dessert cravings while supplying lots of protein. They are not low-cal, of course, so they’re not an unlimited snack at all. I works good for me to cut them in half and wrap each half in foil or a baggy so I have a mid-morning and a mid-afternoon (10-grams-protein each) snack.


  • 23

    I’ve tried SO MANY different types of high protein bars for after a good workout, and these bars are the only ones I’ve found that don’t contain ANY sugar, which is a major plus. I wouldn’t use them as a meal replacement, but rather as a protein source after a workout. The taste is definitely something that you may need to get used to, but the fact that they are gluten free is great. Another good bar to try are the Premium Protein bars. They have 30 grams of protein and about the same amount of calories per bar that the Think Thin bars do (around 230). And while the best tasting bars so far have been the Clif Builder Chocolate Mint and Peanut Butter bars, they contain 20 grams of protein and 20 grams of sugar per bar.


  • 24

    Think Thin Bars are the best I’ve ever had. I have a gluten intolerance and these are allergen free for me. Also, all th eother bars with 20 grams of protein all also full of hydrogenated oils and nasty ingredients which are unhealthy and taste bad. Think Thin Bars are fabulous and delicious!



    I have only hsd the white chocolate raspberry bites, and I thinkthey are very good. I eat low glycemic, and it is hard to find bars that mmrt the requirements for that. These bars are A+ in my book.



    They are da best !! No sugar is de best


  • 25

    They taste AWFUL! Save your money.



    I disagree! these are my favorite bars and I’ve tried them alllll! I think taste is a matter of opinion…the thinkthin crunch is my favorite. it has a thin layer of chocolate and is super crunchy.



    yeah, I have to say these are my FAVORITE tasting of all the protein bars I’ve tried. I love the brownie one.



    I tried the creamy peanut butter and it has an after taste that I couldn’t get past. Couldn’t finish the bar. I will try a different flavor and see if it’s better.



    These are gross. They made me so full I almost threw up. No, I didn’t eat anything for hours afterward so I can see how you might lose weight. I am fairly active, but these are like a bunch of lead balllons. I would suggest running a marathon before or after eating.

    I’m not trying to lose weight. I’m just trying to eat healthy. Sometimes I don’t have time to make a healthy breakfast. Is thinkThin good for a healthy breakfast? Could it cause you to gain weight?



    Think Thin bars are great for breakfast. I eat one everyday on my way to work and they keep me energized and full until lunch time. They do not cause you to gain weight.



    I’ve recommended these bars to so many friends. My next goal is to have the local WM superstore carry it as only one carries it and sells it for $1.53 while Whole Foods sells it at $2. I’ve been eating the creamy peanut butter bar every weekday morning for breakfast and it literally keeps me full for 3 hrs. I remember my first time trying this bar…I wasn’t even halfway through that I already felt a sense of “full”


    Your Name

    I think they are great! I eat them when I’m craving dessert, they are rich and sweet.
