ThinkThin Caramel Fudge

Second review time! After much looking at labels I picked up this ThinkThin (I think it’s meant to be written as thinkThin) Caramel Fudge protein bar. At first glance it looked pretty good, only 1g net carbs! Could this be a winner?

Now I thought I had eaten this before and this would be a good second review. Turns out, I was wrong. I believe ThinkThin have multiple lines and I had some Salted Caramel bar. I only noticed when I saw the bar was coated in chocolate…

ThinkThin Caramel Fudge


At first, you may think that the ThinkThin Caramel Fudge bar has great macros for anyone doing Keto or a low carb diet. After all, the Caramel Fudge bar has only of 1g net carbs per bar, right? Well… that depends on who you speak to.

Each bar contains 21g of Maltitol. Now, whilst Maltitol is a sugar alcohol it actually has a high GI value and will spike insulin. The general advice I’ve seen is to count 3g of Maltitol as 1g of sugar — so you could say each bar has 8g of carbohydrates. Still the effect seems to vary on a person by person basis — so Maltitol might be fine for you.

Maltitol is notorious for one other problem… It can act as a laxative and some people seem to be more sensitive to its effects. So, if you haven’t had a project sweetened with Maltitol before it might be wise to be careful. Although personally, I’ve not had a single problem with Maltitol.

All values are for a single bar (60g).

Total Carbohydrates23g
Sugar Alcohols21g

ThinkThin Caramel Fudge: Nutrition Facts


The flavour of the ThinkThin Caramel Fudge bar is very familiar… it reminds me of other bars I’ve had. I guess I am a sucker for the chocolate and caramel combination.

Unfortunately for ThinkThin, this bar is nothing special. The flavour starts out nice and caramelly, but it fades away. To me the final taste isn’t very nice, I can’t put my finger on it… but it’s close to a tobacco flavour — which is something I’ve noticed before in chocolate and orange chocolate flavoured bars. I guess it’s like a bad version of a Riesen Dark Caramel Chocolate Chew.

The bar has a thin layer of what tastes like dark chocolate. It’s pretty bitter, but that would be fine if the inside of the bar was sweet. Unfortunately, the caramel/fudge centre is pretty rubbish. It’s not sweet and has a very mild flavour.

The ThinkThin bar has the usual chewy texture you’d expect. It’s on the lighter side, — I’ve had some bars that were closer to chewing gum! Thankfully, this isn’t one of those.

If I had a microwave right now, I’d try microwaving this bar. Sometimes a bar is completely different after a quick blast in the microwave, so that gives me something to try if I spot this bar again.


I cannot reccomend the ThinkThin Caramel Fudge bar for number of reasons:

  • Taste is nothing special and doesn’t make up for the choice of sweetener.
  • Slightly high on calories (220kcal).
  • Maltitol can have adverse affects (Insulin spikes, laxative)

Now I’d like to try a few other items from this range if I can find them. Also I prefer to try something multiple times before reviewing it — a mistake caused this review!
