In the diet industry, don’t mistake marketing for evidence. This time around we took the time to write a detailed review of Sweet Sweat, examining the side effects, ingredients, and scientific studies. Also, we read countless dieter reviews and user comments from around the web. Lastly, we summed up all the data we found to give you with the bottom line.

Sweet Sweat Readers: Click here to find out why we're giving away samples of our product, Leptigen.

What is Sweet Sweat?

To start, Sweet Sweat is advertised as a “workout enhancer” that targets problem areas. This sculpting cream [1] is applied to fatty areas such as the buttocks, hips, upper arms and lower back. It contains white snow petroleum, kosher Brazilian carnauba wax, acai, pomegranate, coconut oil, kosher jojoba, camelina, squalane oils, aloe vera extract, vitamin E, and fragrance. It should be used just before a workout and should not be applied over other creams and lotions. Clinically speaking, the product supposedly improves circulation, increases perspiration and fights muscle fatigue. Some users will need to watch for allergic reactions, as is the case with all topical treatments. [2]

Sweet Sweat was introduced in 1970’s and contains some natural ingredients – impressive. The official website and third-party retailers sell the supplement. We like that we found some favorable customer comments and that it seems affordable, but read on…

No Results – “A Common Issue?”

The first thing was the ineffectiveness of Sweet Sweat ingredients. [3] “There are no actual clinical studies provided to support the statements made about Sweet Sweat,” said our Research Editor. “This could be why so many users report seeing no results.” It’s important to note that the only effects science supports are cosmetic cellulite reduction. [4]

“Had high hopes for this product. Really disappointed. No results,” stated a customer. Experts agree. [5]

“Save your money. It’s like putting vaseline on your stomach,” reported another.

We did find some users who noticed some changes. One reported, “I have used this before and it works well sweat within 3 mins of doing cardio.” Effects could be a result of the combination of cellulite cream and lifestyle changes. [6]

“Sweat in minutes and no residue in your hands,” commented a user.

Numerous User Complaints about Sweet Sweat – “A Big Problem”

We certainly encountered plenty of customer complaints posted online about Sweet Sweat. In fact, one user said, “This doesn’t do anything for me at all. It’s a waste of money.” [7]

“Greasy, stinky – was walking outside for an hour in 90 degree heat not as much sweat as I would have like – real messy cleanup,” said another customer.

Though we did find more negatives than positives, there are people out there who liked the product. A buyer offered, “I put it on my waist and wrap plastic around. Smells good.”

One user said, “I like this stuff. It keeps my muscles from getting stiff.”

Our research has concluded that if there is a particular part of a diet product that’s concerning, like negative reviews, the probability of long-term results is slim. So, if Sweet Sweat is hindered by user problems, we see a bigger issue. Plus, it doesn’t help that major retailers like QVC have been sued for making false claims about anti-cellulite creams. [8]

The Science – “Supported by Research?”

There’s no documented clinical research presented on the official website to support weight-loss claims regarding Sweet Sweat. Even when it looks like science is giving the thumbs up, the results often report on the appearance of cellulite. [9] At DietSpotlight, we need to find published science that backs the product’s ingredients. With Sweet Sweat, we only see a big red flag, because there’s no solid science used as evidence.

The Bottom Line – Does Sweet Sweat Work?

So, are you heading to the gym with Sweet Sweat? Well, we like that it contains a few natural ingredients and that longevity of the company, but the lack of research supporting the claims is a bit concerning. We’re also skeptical about this one due to negative customer comments about it not working.

If you want long-term weight-loss results, we suggest going with a product containing some clinically-tested ingredients and is supported by positive customer feedback.

Among the best products we’ve seen this year is our product called Leptigen. The formula is a blend of four ingredients. All clinically-tested with results often published in journals such as The American Journal of Clinical Nutrition.

Also, we’re so confident that you’ll love our supplement, that we’re offering a Special Trial Offer, which is a good sign.

Previous Sweet Sweat Review (Updated May 6, 2014):

What You Should Know about Sweet Sweat

We have reviewed lots of interesting products over the years, but Sweet Sweat is one of the more interesting products. Interestingly, it is a creme like Testim though not for testosterone. The cream is supposed to target areas that don’t respond to working out. At first glance, there are no ingredients in the formula that would increase circulation to a problem area, but when we looked more closely we find green tea. Green tea is a source of caffeine and caffeine increases heart rate when taken in supplement form. We’ve noticed caffeine in slimming creams as it is proven to dehydrate the space between fat cells making skin appear smoother, but that is not the same actually slimming the area or increasing circulation. And if you're looking to slim down perhaps PhenQ could be of assistance with its boost in energy levels and fat blocking production. We found Sweet Sweat on an official website. The website is easy to navigate and it provides information like an ingredient list and instructions for using the cream. There are no clinical studies supporting caffeine cream for increased circulation listed on the official website.

List of Sweet Sweat Ingredients

White Snow Petrolatum, Kosher Brazilian Carnuba Wax, Acai, Pomegranate, Coconut Oil, Kosher Jojoba, Camelina, Squalane Oil, Aloe Vera Extract, Tocopheryl Acetate. You can find our article on the health benefits of aloe vera, which can promote weight loss and overall help patients with diabetes.

Product Features

If you are having trouble slimming your upper thighs, all you need is a touch of Sweet Sweat and you will see the area change, according to Sports Research the creator of Sweet Sweat. We would love to believe a cream could counteract fat storage, but we find that hard to believe. The ingredient list supports slimming, but not weight loss. White snow petrolatum and kosher Brazilian carnuba wax soften the skin. These ingredients have no slimming effects. Acai and pomegranate are antioxidants that may help improve skin health, but they will not affect “trouble” areas. Camelina is green tea, which likely includes caffeine. Caffeine may dehydrate between fat cells leaving the skin looking slimmer, but the effect is only temporary. Aside from lathering up the skin with Sweet Sweat for weight loss, Catalyst can help with muscle growth, improving recovery, strength and endurance.

Advantages of Sweet Sweat

  • Contains caffeine to give skin a slimmer look.
  • May improve skin health.
  • Will likely soften skin.
  • Available on the official website.
  • All ingredients are listed online.

Disadvantages of Sweet Sweat

  • Will not improve “trouble” areas.
  • The formula is nothing more than caffeine, antioxidants and skin softeners in a bottle.
  • Will not increase metabolism or decrease hunger.
  • Makes claims that are not support by clinical research.


Sweet Sweat is an interesting product, but it is not a product we believe will affect weight loss. The product description leads the visitor to believe the formula will help them achieve fitness goals by increasing blood circulation to “trouble” areas. Like how Alpha Fuel XT's "studies" tell us nothing about the product. Trouble areas are not affected by spot reducing or caffeine creams. Most of the ingredients in the formula are antioxidants and skin softeners. Dieters looking for a weight loss supplement are not likely to find the support they need from Sweet Sweat.

Sweet Sweat Scientific Abstracts:

Coconut Oil

Cholesterol profiles were observed and measured in plasma samples gathered following an all-night fast. Mean lipid values for said profiles were high density lipoprotein cholesterol (HDL-c) (40.85 ± 10.30 mg/dL), total cholesterol (TC) (186.52 ± 38.86 mg/dL), triglycerides (130.75 ± 85.29 mg/dL), low density lipoprotein cholesterol (LDL-c) (119.42 ± 33.21 mg/dL), and the TC/HDL ratio (4.80 ± 1.41). The linear regression models had been utilized to gauge the association between coconut oil consumption and plasma lipid outcome following an adjustment in total energy intake, body mass index, age, menopausal status, number of pregnancies, household assets, education, and urban residency. The intake of coconut oil for dietary purposes was absolutely related with HDL-c levels. [1]

Pomegranate Seed Oil

The potential for pomegranate juice as an antioxidant is more than that of green tea or red wine, which is triggered through ellagitannins and hydrosable tannins. Pomegranate juice has been noted to decrease macrophage oxidative stress, lipid peroxidation, and free radicals. In addition, the juice from the pomegranate fruit prevents the growth of cells and actually triggers apoptosis, which could cause its anticarcinogenic effects. The juice contains ellagitannins, which can block promoter inhibitions of some inflammatory markers. [2]

Acai Pulp Oil

Following the intervention there had been a substantial raise of EGF (p = 0.021) and PAI- 1(p = 0.011) within the overweight women participants in the study. In addition, there was a raise in body mass index (p = 0.028), body weight (p = 0.031), percentage of truncal fat (p = 0.003), triceps skinfold thickness (p = 0.046) in eutrophic women. The thickness of skinfold (p = 0.018) and total (p = 0.016) body fat reduced in overweight women. Total protein (p = 0.049) had been reduced as well, mainly due to the decrease of globulin (p = 0.005). The consumption of 200g acai pulp had modulated the EGF and PAI-1 expression, potentially by modulation of acai on composition parameters of the body, inflammatory, dietary, clinical, and biochemical, had resulted in the redistribution of body fat in the trunk region, which was presumed to be an increase of visceral fat. [3]

Aloe Vera

There had been a significant raise in gastric acid levels within the aloe vera study group in comparison with gastric ulcer participants (p<0.05). Although, there had been no differences in acid output within gastric ulcer and aloe groups with intact group. Following aloe vera administration, the brain water content amounts contained no differences with intact and gastric ulcer participants (p<0.05).The duodenal water content within the aloe subjects were substantially decreased when compared with the intact group (p<0.05), however, gastric ulcer patients showed no important differences with intact and aloe group. In conclusion, the administration of aloe vera has a certain deterrent effect on gastric acid output. [4]

Sweet Sweat Side Effects:

In a world that offers hundreds of natural supplements, some customers often think this term is synonymous with side-effect free. There is always a potential for a negative reaction with any formula, so even though Sweet Sweat side effects are fairly uncommon, it doesn’t mean they don’t happen to some people.


A rash is transformation in the skin that affects its color, texture, and appearance. A rash can inhabit a small area of the body, or a much larger surface depending on the condition. It may cause itching, bleeding, bumps, or blister and may become extremely painful.

What causes a rash?

There are many forms of rashes including eczema, lichen, granuloma annulare, and pityriasis rosea. Any number of factors can play a part in the cause of a rash, typically allergies or genetic conditions. Often times the urge to scratch could make the rash worse or cause it to become infected.


Diarrhea is the frequent passing of loose or watery stools. This condition isn’t typically life-threatening, however if the problem persists it may be an indication of a more serious medical condition.

What causes diarrhea?

Diarrhea is usually caused by an infection in the gastrointestinal tract. Microbes such as bacteria, parasites, and viruses invade the gastrointestinal tract, causing the infection. Irritable bowel syndrome (IBS) may be another factor in this symptom. [1]


A headache is a continuous dull, moderate, or severe pain in the head or neck. The most common forms of these are migraine, tension, and cluster headaches.

What causes a headache?

Headaches happen when the nerves, blood vessels, and tissue around the brain are disturbed. Sinus infections are known to cause acute headaches. These are aches that come and go after a short period of time. Illness, stress, and personal environmental factors, such as secondhand smoke, can also be a factor.

Excessive Sweating

Excessive sweating (or hyperhidrosis) is the experience of uncontrollable perspiration. Harmless in most cases, it could cause dehydration, electrolyte imbalance and muscle cramping.

What causes excessive sweating?

Your sweat glands produce this salty liquid to cool the body after it’s been overheated. This usually occurs after a workout or strenuous activity. However, if the sweating is profuse and lasts for an abnormally long period of time, it may be the result of a more serious disease or a malfunction in the nervous system. [2]

Sweet Sweat side effects are few and far between, but there have been some reports of adverse reactions such as headache, rash, and diarrhea. In order to safeguard yourself from any issues, it’s always best to talk with a physician before taking any supplement, especially if you are pregnant or nursing, under the age of 18, have a medical condition of any kind, or are taking prescription medications.



Sweet sweat is a muscle cream used before a work out to increase perspiration and prevent muscle weakness. Though side effects are extremely rare, we did find a few mentioned in customer reviews.


“This stuff gave me a horrible rash on my arms kind of like heat rash it’s super painful.”    Adriana


“Made me sweat a lot but also caused itching and a rash.”    Mia


“This product caused major diarrhea, like 6 times within two hours…Have no idea what going on with my body at the moment.”    Lucy


“Not ideal for sensitive skin. Prone to rashes.”    Juanita


“It gives me a headache.”    Bailey


“Product works but it caused itching and irritation.”    Julie


“Yes I noticed a little more sweating but it also irritates my skin a little bit.”    Jason


“Not for me. Made me itch. Stop using it.”    Jerome


“Avoid like the plague! Causes severe rash after about three weeks of use.”    Brownie


“After a couple of uses of the gel and belt I developed miliaria rash.”    Ashley


With trying new weight loss products, there is never a guarantee it’s going to work wonders. One product we are very excited about is Leptigen. We took a look at their clinically tested formula and plethora of positive customer reviews talking about the results they were seeing with Leptigen, and we are convinced this has to be the best weight loss supplement that’s been invented.

Sweet Sweat is a topical cream that, when applied to the skin, increases heat production and sweating. The idea is that the more you sweat, the more calories you burn - leading to weight-loss

We researched the Sweet Sweat ingredients in order to give you the information you really want.

Organic Coconut Oil

Coconut oil is considered a “superfood”, primarily because it contains a large of amino acids.

What Is It Supposed To Do?

Organic coconut oil has a large amount of health benefits for the body, including skin care, hair care, heart disease, weight-loss, immunity, digestion, and other health conditions.

Clinical Research

According to a study published in ISN Pharmacology, “In conclusion, VCO [virgin coconut ol] is a cheap oil source containing high concentration of MCFAs which in the current study had shown beneficial effect in WC [waist circumference] reduction especially in males without any deleterious effect to the lipid profile.” [1] However, the same results were not seen with women.

Pomegranate Seed Oil

Pomegranate seed oil is derived from the fruit. The fruit can be grown naturally in Southern Europe, Africa, Southeast Asia, and the Middle East.

What Is It Supposed To Do?

Pomegranate seed oil is thought to have a number of health benefits for the skin. It is also thought to help lower cholesterol.

Clinical Research

In a study published in Evidence-Based Complementary and Alternative Medicine, researchers concluded, “High-fat-diet- (HFD-) fed mice treated with pomegranate seed oil resulted in decreased body weight and fat mass in CD-1 mice when compared to the control group, although no differences were reported regarding the lean mass between both groups [64].” [2] However, this study does not include human subjects, which makes the results questionable related to weight-loss humans.

Acai Pulp Oil

The acai fruit grown naturally in Amazon rainforest and the oil is naturally green, despite its purple appearance as a fruit.

What Is It Supposed To Do?

Acai oil is primarily used as dressing for salads. It is also used in shampoos, soaps, and moisturizers.

Clinical Research

In a fact sheet written by the National Center for Complementary and Integrative Health, writers mentioned, “No independent studies have been published in peer-reviewed journals that substantiate claims that acai supplements alone promote rapid weight loss. Researchers who investigated the safety profile of an acai-fortified juice in animals observed that there were no body weight changes in rats given the juice compared with controls.”

Brazilian Carnauba Wax

Brazilian carnauba wax is made from Copernica prunifera. It is only grown in certain Brazilian states, including Piaui, Ceara, and Rio Grande de Norte.

What Is It Supposed To Do?

Brazilian wax is used for automobiles, dental floss, shoes, instruments, floors, furniture, waxes, polishes, and some sweets.

Clinical Research

When we were looking for clinical studies done on Brazilian carnauba wax and its effect it had on weight loss, we could not find anything.

Weight loss can be an ongoing issue never finding the right balance of diet and exercise. Leptigen is a clinically proven supplement suggested to help boost metabolism and fat loss. Dieting and exercise can be achieved with this product from studies supporting a boost in energy levels, absolving weight loss plateaus and weight loss.

Can I use the waist trimmer for swimming as well?

Hi! For detailed product and usage instructions, please refer to the Sweet Sweat official website for more information.


This is a silly comparison! I LOVE Sweet Sweat and by the way it isn’ s diet anything. It is what you said in your 1st line… “workout enhancer” and to the person that said they used it and walked in the sun and didn’t sweat much…I say Baahhhh Haaaa also note that you have to follow the directions such as no body lotions prior, clean skin, and do not rub in completely. I run and I am over fifty. This stuff is great! Think of it more as a pre-work out. It warms the body mussels so that they do not hurt. you cannot use this and not work out people! This along with belly trimmer and of course working out/running it works.

Blanca Lua

Do you have too take the gel cream for it to work ?


Hi Blanca! Yes the cream is the Sweet Sweat product, so it will need to be used.


Is sweet sweat alright for the HCG diet?

Hi Justina. Sweet sweat cream doesn’t have anything to do with the hcg diet meal plan. Depending on the hcg diet info you follow, the very low calorie intake could be more of an issue. We suggest grabbing the ingredients for Sweet Sweat and the directions for your hcg diet meal plan and asking your doctor to be sure.

I believe the stuff works. I experimented by putting it on only one arm prior to cardio. After about 10 min it was clear the stuff was working. There was a pool of sweat under the elliptical only on the side of application. At the end of 30 min it was in believable on the amount of perspiration I saw. I was convinced.

I LOVE this! After I take it of, my skin actually looks, and feels SO much smoother! Excellent product!

Your Name

I used sweet sweat sample that a friend gave me. Im not a runner by any means and i always get muscle fatigue in my calves along with pain from my shin splints. I decided to try the sample to see what it does and id have to say that my calf fatigue was a lot less. I typically stop during my run about 4 or 5 times when trying to run 2 miles but i was able to keep going and stopped running for about 10 seconds just to catch my breath instead of for my leg fatigue. I was actually able to run an additional mile at a harder pace than I have ever run before. It worked for me for sure maybe its just not for everyone which is why they say it didnt do anything.
