Skinny sauce: Brown sauce

Best low calorie sauces - Skinny sauce brown sauce

The colour and texture all received the stamp of approval from me. I tried this with sweet potato, chicken and cauliflower. There is a subtle taste to the sauce, I’m probably more used to brown sauce having slightly spicy tones to it, similar to what you’d encounter with regular brown sauces. Saying that, perhaps a sprinkle of spice on the sauce would achieve this.

In terms of calories, regular brown sauce is relatively low (18 calories per 15g serving), but if you’re heavy-handed with your sauces, you’re trying to cut sugar (3.5g sugar per 15g serving) or a some calories from your diet, then perhaps the skinny brown sauce may the way to go.

Reviews for the sauce are all positive, with one consumer claiming that it’s not as acidic as a well-known brand that they use.

Skinny sauce: Garlic mayo

I wouldn’t be a big fan of garlic mayonnaise at the best of times but when it came with the other samples, I had to give it a go. I used this sauce to flavour my tuna salad. On first impressions, there was a subtle taste of garlic from the sauce, but I think it may have been better accompanied with other food, e.g. used as a dip or in a sandwich. Then again, I’m not a fan of this flavour, so I’m probably not the best judge. Consequently, I turned my eye to the reviews, which there are pages of by the way! Almost all positive reviews were observed and most people rate this as one of their favourite sauces.

The colour of the sauce passed the visual test, but the sauce itself was slightly runnier than regular garlic mayo sauce. With regard to nutrition, it’s unfortunate that garlic mayo doesn’t come in as many reduced-fat versions as mayonnaise; in fact, you’d be doing well to find a low fat garlic mayonnaise! Consequently, the calories do add up rather quickly. A 15g serving of garlic mayo offers 44 calories compared to zero calories in the skinny sauce version.

Skinny sauce: Original mayo

Best low calorie sauces - Skinny sauce original mayo

I also tried this one with a tuna salad and I was honestly struggling to pick up any flavour from it. Since I only had the sample to try, I didn’t get to use it with other foods. But before you abandon this sauce as a choice, I would recommend trying it with other foods, now let me explain why. From reading the reviews, consumers seem to love this sauce and have found it to be an ideal accompaniment to their chips and sandwiches. One reviewer even claims that it took her a few rounds of using it before she decided that she liked it, so much so that she even bought it on a subscription offer as a recurring order.

From a nutritional standpoint, it only contains 1 calorie per 15g serving, 0g fat and 0g sugar, making it a low calorie, zero fat and zero sugar sauce! Considering there’s so many variations of mayonnaise available on the market, let’s compare how much calories, fat, sugar and salt could be consumed based on the mayonnaise you choose.

As you can see from the table above, there’s a significant distinction between the nutritional value of regular mayonnaise, lighter than light mayonnaise and the Skinny Co. version. The skinny sauce is the leading contender by miles when it comes to the sauce that’s optimal for reducing calorie intake and also reducing your sugar, fat and salt consumption.

What’s also noteworthy is that the lighter than light mayonnaise compromises for the loss of fat with a rather elevated sugar level, a common trend that’s observed in low fat products. Such practices of including hidden sugars in foods are what is leading to an epidemic of diabetes throughout the world.

It’s evident from the above comparison where hidden calories lie and concludes for many people why they struggle to lose weight or are looking for low calorie options! Ultimately, it’s up to you which you choose whether that’s based on flavour, nutrition or cost.

Skinny sauce: Smokey BBQ sauce

Best low calorie sauces - Skinny sauce Smokey BBQ

I tried the low calorie BBQ sauce with an omelette and it added a nice sweetness to the savoury omelette flavour. There’s a slight sweetness to the flavour, the taste isn’t overpowering either, it’s a mild taste. I’d definitely buy this again as the sugar content in regular BBQ sauce is astronomically high (4.4g sugar per 15g serving), and when you consider that it’s more often than not going to be more than a 15g serving, the sugar really starts to add up. The calories in regular BBQ sauce are relatively low (21 calories per 15g serving), but again they’ll add up too the more you add the sauce.

This Skinny sauce version probably doesn’t emit as strong of a flavour as regular BBQ sauce, but after a few goes with it, I didn’t notice the difference. From reading the reviews, this is certainly one of the most, if not the most popular sauces that the Skinny Co. have to offer. Consumers have tried this on a range of foods, such as with sausages, chicken, toasted sandwiches, and the response is very positive. The skinny sauce is definitely an easy way to avoid hidden sugars. They are also a healthier alternative to regular versions while achieving significantly lower sugar, salt and calorie intake.

Skinny sauce: Sriracha hot chilli

Best low calorie sauces - Skinny sauce Sriracha hot sauce

This is definitely a contender for my top favourite sauces! I like my food to have a bit of spice, but not the ‘steam coming out of your ears’ level. I tried this sauce with chicken, vegetables and potatoes and it complimented them all perfectly. Fortunately, this sauce achieved the perfect level of spice to add a kick but not enough to have me running for the fire brigade!

From my memory and a quick Google of the regular sriracha sauce, the texture and colour of the Skinny sauce looked practically indistinguishable. As for the nutritional benefits of choosing the Skinny sauce version over a regular sriracha sauce, you’re consuming about 3g sugar and 15 calories per 17g in regular sriracha, compared to 0g sugar and 2 calories per 20g Skinny Sauce sriracha sauce. The greatest benefit of moving from the regular version to the no calorie sriracha sauce is the massive reduction in salt that you’ll achieve, with 50% less salt in the skinny sauce version.

The reviews are extremely positive for this with another like-minded person claiming that this sauce is one of their favourites. Another reviewer suggested that this tastes exactly like buffalo sauce.

Skinny sauce: Thousand Island

Best low calorie sauces - Skinny sauce

This is actually one of the sauces that I bought a whole bottle of without even trying the sample. I was fascinated to see how well it would compare with the regular thousand island sauce, which typically has what looks like a thousand calories per bottle too! Ok, that may have been a slight exaggeration, a 100ml serving has 1029 kJ which is really 245 calories per 100g, which is still staggeringly high!

The texture and colour all looked normal to me. Upon the first few taste tests, I had a feeling that it didn’t taste quite the same as thousand island, but then again it’s been years since I’ve had the real thousand island sauce. Whatever way you look at it, this went down an absolute treat, I mostly used it with salads and I had this used up in about 2 weeks. Needless to say, I’ve invested in a second bottle and I’m at a loss just waiting for it to arrive.

Skinny sauce: Tomato ketchup

Again, I used this sauce with an omelette. Upon first inspection, the sauce had an orange tinge to the colour which is interesting considering tomato sauce is usually a strong red colour. My first taste of the sauce was positive, and I did get a ketchupy flavour from it, albeit slightly milder than a standard tomato ketchup.

I am one of those people that loves ketchup, I believe it can compliment almost any food, and so the taste test on this sauce was a particularly important one for me. I probably would go with the reduced-sugar tomato ketchup myself as I feel it maintains a bit more flavour while not having to endure the excess sugar that regular ketchup provides (15 calories and 3.4g sugar per 15g tomato ketchup). Saying that, I’d probably get accustomed to the Skinny Sauce ketchup too if I tried it more times, and there would be the added benefit of zero sugar and no salt too.

These sauces look great!! Thank you for this review. I knew sauces had a lot of sugar but I didn’t know this much.

    Sharon · 06/10/2020 at 6:45 PM

    Hi there,

    I’m glad you like them. Yes, it’s definitely scary to see the quantities of sugar in them, low sugar sauces are certainly the way forward!

    Best wishes,

What a beautiful review! I have heard about Skinny sauce before, but to be honest, never checked out any of them personally. I have been avoiding industrial food, sauces and all similar for a long time now, but it always means introducing some sort of compromise into our diet, ie. we are giving up this and that, and so on. After reading your review (in which I really like that it contains your personal experience with them), it seems as a great solution for hugely cutting back on unhealthy sugar and carbs in general while still being able to enjoy some (for us long forgotten) sauces with food we like.
Thanks for being so thorough in presenting these.

Hi Sharon,

SkinnySauce is a good name, and it is impressive when you look at the logo. Among all the sauces, Sriracha Hot Sauce is also my favorite because it can add more flavor to the meals I eat. I am stunned that they reduce calories, carbon, and sugar comparing to normal hot sauce. Thanks for your recommendation today. I will love to buy them & taste them soon.
