thinkThin Bars Review - 11 Things You Need to Know

thinkThin bars are meal replacement snacks that are both sugar- and gluten-free. The company promises no sugar, but we were surprised to find out that each bar contains 20 grams of carbs — over 200 calories! A high caloric intake could be fine for users who exercise, but regular dieters might have trouble keeping their weight down.

Our research team examined the science and side effects to see if thinkThin bars help with weight loss. To reach the bottom line, we compared these meal replacements could provide “deliciously natural nutrition” as they claim.

thinkThin Bars can be purchased through their Official Site.

The History of thinkThin Bars

Lisanne Falsetto founded thinkThin in 1999, with the stated aim of providing nutritious food that supports wellness. They use only natural ingredients in their products and follow three simple mantras: pack it with protein, add zero sugar, and have no gluten. For almost two decades, they have grown their product range to more than a dozen product categories.

Now, who wouldn’t want to be in the same company as a celebrity superstar just by eating Think! nutrition bars?

Where to Buy?

Where to Buy thinkThin Bars

With sales of almost $100M annually, thinkThin enjoys national distribution through retailers, including:

  • Walmart
  • Target
  • Amazon
  • Official website

thinkThin Products

Then you have six other categories which are slightly different from the usual thinkThin power bars, but equally delicious: protein cakes, protein bites, protein and fiber oatmeal, probiotics powder, smoothie mixes and an entire category dedicated to vegan products.

Each of these categories has at least 4 to 5 products some categories have more, so you can pick and choose throughout the year without getting bored with the same flavor. If you are still not satisfied with all of these choices, you can also find some special categories:

  • Limited Edition
  • Specials
  • Trial Packs
  • Variety Packs

There is now a new 150 calorie Think! Protein+ Bar available on their official website.

Michelle Kessler, CEO of thinkThin, explained the rationale behind the different product categories and plans for more categories in the future.

Describing ThinkThin nutrition bars,  she said, “We like to think we are the oasis in the rainbow of confusion with a presence that tends to stand out in a very crowded, busy, colorful shelf.”

While developing new products or upgrading existing product lines, thinkThin tries to tread the middle path between regular tastes and niche tastes, so that it can cater to both categories of customers.

They have put together a team dedicated solely to watching trends in the healthy food space, and accordingly experimenting with newer flavors or product lines to keep up with the evolving tastes of the ever-discerning customer. This team takes less than a year to zero in on a new product line or flavor, to get it ready to go to market.

ThinkThin Benefits

ThinkThin Benefits

Think! bars are healthy food options loaded with benefits, the makers claim.

Proteins

This is a food group that gives us energy for regular as well as heavy physical activity and is also the star in the thinkThin lineup of ingredients. Every bar promises 20 grams or more of proteins. This amount of protein kick starts the day with a much-needed spike in energy levels, prevention of fatigue and maintenance of energy levels.

Gluten-Free

Gluten, mostly found in grains, has been found to have numerous harmful effects on our body, like inflammation of the gut, intestinal permeability, celiac disease, autoimmunity, etc. All thinkThin products are gluten-free.

They do have a word of caution on their website about their oatmeal products because the oats could have come into contact with some levels of residual wheat.

ThinkThin ingredients

Fiber

The fiber in our diet has several benefits. It is a natural appetite-curbing agent and helps avoid those hunger pangs. Therefore, it is a natural way to keep tabs on your weight. thinkThin has a whole category of products with high fiber, and some of their products in the other categories also have high fiber content.

Whole Grains

According to ChooseMyPlate, there is a host of benefits associated with the intake of whole grains. Reduced risk of controlling constipation, weight control are just some benefits which we all get; additionally, it is good for pregnant women. The oatmeal products benefits.

  • Chocolate coating

Side Effects

Do thinkThin Bars Work?

Regarding giving healthy proteins in a gluten-free product, ThinkThin protein bars nutrition facts seem all right. However, we were curious to investigate the no-sugar claim and also the extent of carbs in thinkThin bars.

Of the many products they have, we checked a few and found that each bar has over 20 grams of carbohydrates and more than 200 calories. Both of these seem to be slightly on the higher side, even though we are promised zero sugar.

Maltitol, a hypocaloric sweetener, is the ingredient used by thinkThin to replace sugar, and we also wanted to check if maltitol has any other adverse outcomes.

According to The Journal of Molecular Medicine, maltitol doesn’t seem to have any adverse effects on plasma glucose and serum insulin levels.

The same study concluded that if maltitol in bakery products replaces sucrose, the caloric content is reduced substantially.

According to The Journal of the Science of Food and Agriculture, it seems that the ‘too good to be true’ statements of naysayers regarding the zero sugar claim of thinkThin might be unjustified after all, since it appears to be supported by scientific studies that the ingredient used to replace sugar does not have any adverse effects.

ThinkThin weight loss

So does thinkThin work? In terms of their stated objective of thinking thin, it seems to be stretching it a bit with 200 plus calories in each bar.

For a person who spends hours working out at a gym, they would work fine, but for a regular person who is grabbing one of these bars just because he doesn’t have time for a proper meal, the calories and carbohydrates in these bars might start adding up, as per some of the users who wrote thinkThin bars reviews.

However, let us delve a little deeper to see if energy bars or protein bars like thinkThin work. The intake of these bars is effective only when we keep the following in mind:

  • Watch the amount of fat in the bars, within 10 grams is best.
  • Too much fiber could be a problem, so 3-5 grams should be the limit.
  • Especially for people with a regular lifestyle, the calorie count of a bar is significant. So unless you are an athlete, an ideal bar should have less than 200 calories.
  • A person looking to replace meals with Think! bars for weight loss must ensure that there are enough proteins in the bar, and on that count, thinkThin scores very well indeed, and is packed with proteins.
  • The need for constant meal replacements is a myth, so we should ensure that we keep eating some real food alongside thinkThin. Even juice or a salad or some fruits would do.

thinkThin Product Warnings

Since several customers nowadays prefer to go vegan and even avoid dairy products, thinkThin has informed the users that their products are manufactured using shared facilities.

Those facilities might also be used to manufacture other products containing peanuts, nut meats, soy, milk and egg products.

This is a fair warning from the company, although we think it won’t make too much of a difference to the product or its ingredients.

What Users Are Saying

“I have been eating Quest Bars for a year and needed something new. I tried these Think Thin bars and they are WAY better than Quest bars. They have a coating over the whole bar and they are much softer than Quest bars. Now I eat these every day. Lemon is my favorite so far but the chocolate ones are amazing as well.”

“There isn’t anything wrong with these other than that I didn’t like the taste. I was looking for a non-protein tasting protein bar and these were not it. Unfortunately I won’t be ordering these again – But at least my husband will eat them so they won’t go to waste.”

“This flavor is really gross. I’ve had the chocolate peanut butter and that flavor is really good. But this one is just nasty.”

The Bottom Line on thinkThin Bars

What are our final thoughts on Think Thin protein bars? We like the longevity in the market and the positive feedback we saw online. But, we have reservations about the bars as they relate to weight-loss. The high-calorie count could be a detriment to dieters, and the sometimes-intense abdominal discomfort associated with that much protein and maltitol may discourage someone from trying to trim down.

If you are trying to lose a few pounds or get a little bit more trim, you should probably look for a product that has proven effects.

Among the best products we’ve seen this year is one called Noom. The program comes with one-on-one support via human coaching, expert resources, tools, and articles, personalized meal plans and more. Then there’s the fact that clinical research shows Noom just works.

Also, the company behind Noom is so confident in their weight-loss app, that they’re offering Dietspotlight readers a free trial.

    Marie (Verified Purchase)

    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.

  • This product taste so good
    Buddy (Verified Purchase)

    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.

    Holly (Verified Purchase)

    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.

      Protein bars are not intended to help you lose weight really. These bars have 240 calories in them. These can be use as diet supplementation or meal replacement. For example, I eat up to 7 small meals a day and always include a protein source. While real protein sources are best (chicken, fish, lean meat, egg whites), sometimes we don’t always have these readily available. I use these as one of my meals alongside of a raw veggie. If you are looking to restrict calories, I would eat a half a one alongside a veggie, as someone suggested.

      Hi Anon! All users are different and can experience different weight-loss results, but exercise in conjunction with a healthy diet and supplements have shown to help with weight-loss.

  • Take refined sugar out of your diet
    Lindsay (Verified Purchase)

    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.

  • I love the taste of Think Thin bars
    Rick (Verified Purchase)

    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.

  • Enough of that
    craig (Verified Purchase)

    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).

  • I give A+ rating.
    connies419 (Verified Purchase)

    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.

  • The best tasting bars i ever used.
    Erin (Verified Purchase)

    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.

  • Think Thin Bars are the best
    Ivy (Verified Purchase)

    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!
