In the weeks that led to this review, I figured out whether Ultimate ThermoFit actually works. We dug deep into the ingredients, side effects, clinical research and customer support. After reading dieter comments by the hundreds, we gathered up all the information. Then, we refined and condensed to give you the facts you need.
What is Ultimate ThermoFit?
First thing, Ultimate ThermoFit is a thermogenic fat-burner. The ingredients are Capsimax, raspberry ketones, acai fruit, green tea leaf, bitter melon, dandelion root and gymnema leaf. The dieter takes one capsule, two to three times per day to supposedly promote weight-loss. The product is portable so you can take it anywhere you go.  
Ultimate ThermoFit is a product from It Works, a company that started offering weight-loss solutions in 2001. The supplement is available through a member of the distribution team or the official website. We like the use of some natural ingredients and supportive customer service team, but read on…
Poor Customers Reviews – “Like It?”
Our first concern with Ultimate ThermoFit ingredients is that they may not offer what customers are looking for in a weight-loss formula. “The dieter wants a product that just works,” says our Research Editor. “If the supplement sells something that may not help shed the pounds then why waste the money?” 
“The only thing it did is make me choke on it, everytime I took it, bad taste in the mouth…and lots and lots of gas!!!,” one dieter says.
“Once I started using it, I hit a wall and did not drop weight,” another customer claims.
Yet another buyer offers, “The product is not what it racked up to be! Do not waste your money!”
Though there are some unhappy customers, there are also some that like the results. As one said, “You take it, you drink the water, you eat better, and you see results.”
Another offers, “I stared ThermoFit few days ago and it has given me the energy to get up and exercise.”
Ultimate Thermofit and MLM – “Sales Push”
Ultimate ThermoFit uses MLM marketing to sell products. With this type of sales it can be difficult to buy a small supply for personal use as the distributor is trying to bring you in as a seller, not a client. “This is mainly just a pyramid scheme. You start by selling so much, you recruit a team, they sell so much which gives you a bonus on top of your sales,” claims a customer.
“The fact that EVERY single 5 star review for this product comes with a distributor’s contact info tells me enough NOT to buy this product!,” says one dieter.
A distributor offers, “If you are interested in purchasing with someone that can guide you, I will be honored to do so.”
Yes, there is clearly a sales push, but not all sellers take it too far. One customer said, “Buying it through a distributor does get you a better discount.”
Another offered the same advice, “Get the product from a distributor to get it for the discounted price.”
In our research if there is a negative, like poor customer reviews, the dieter may not achieve long-term success. If Ultimate ThermoFit is indeed as ineffective as buyers claim, this may be an issue.
Does the Science Offer Support?
If you are looking for research to support the claims associated with Ultimate ThermoFit you won’t find any.  It Works does not publish “science” for dieters to read. We searched for studies that backed up the company’s statements, but we found none. DietSpotlight is on the lookout for clinical evidence and if that’s not there, we may have to throw in the towel.Also: read our Leptigen Weight-Loss Kit review »
The Bottom Line – Does Ultimate ThermoFit Work?
Should you be running out to buy up all the Ultimate ThermoFit? We appreciate that the company does have a professional looking headquarters, international presence and a good BBB rating, but we can’t give this one the thumbs up because weight-loss claims are not backed by science and poor customer reviews leave the dieter questioning the effectiveness of the formula. We’re also concerned that the MLM marketing could cause trouble buying a small amount of the supplement.
If now is the time to drop the weight, we suggest trying out a supplement that works with clinically proven ingredients that aren’t associated with harmful side effects. Having the opportunity to buy just one bottle, if desired, is also a positive.
Among the best products we’ve seen this year is one called Leptigen. The formula is comprised of a proprietary blend of some clinically-tested ingredients, showing the supplement helps to quicken fat loss and raise metabolism. We couldn’t find any reference to negative side effects and dieter reviews claim users are seeing great results.
Also, the company that produces Leptigen is confident enough in the formula to offer a Special Trial Offer, a good gesture.
Previous Ultimate ThermoFit Review (Updated April 3, 2014):
What You Should Know About Ultimate ThermofitUltimate ThermoFit claims to be an all-natural energy boosting and fat burning supplement to help you reach your weight loss goals. With so many products on the market today claiming to do just that, it can be overwhelming trying to make a decision about which one you should use to reach your weight loss goals. It's also nice to see It Works has a satisfactory BBB rating. Take a look at this review to learn more about the product and its ingredients to help you decide whether or not the supplement is the right one for you.
Ultimate Thermofit List of IngredientsUltimate ThermoFit contains the following ingredients:
- Vitamin B12
- Capsicum Fruit Extract
- Raspberry Ketones
- Acai Fruit
- Green Tea Leaf Extract
- Guarana Seed Extract
- Bitter Melon Fruit Extract
- Dandelion Root Extract
- Gymnema leaf Extract
Product FeaturesUltimate ThermoFit, as shown on the official site contains several natural ingredients that can help boost your energy levels and help you burn more fat (some of which are found in other supplements like EndoTrim). Some of these ingredients are found in similar products like Phenocal and Burn 60. However, on the other hand, there are also several ingredients in the formula that while natural, do not really have a purpose in terms of weight loss that may produce some side effects. Ingredients such as capsicum fruit extract, raspberry ketones, and chromium may help you burn fat and lose weight by elevating the metabolism through raising the core body temperature. Similar to how the leptin in Venus Factor is said to quell hunger. Acai fruit has no known direct link to weight loss, though the antioxidants may help improve overall health. Another product that claims to improve health and the immune system is Nopalea. The final five ingredients are included in a very small proprietary blend that cannot contain the right amounts for those ingredients to be effective. Vitamin B12 is essential to energy production, but is available on its own as a supplement for much cheaper than this supplement. Most if the ingredients in this formula will produce nothing but water weight loss, so you will not see long term weight loss results.
- Ultimate ThermoFit contains some ingredients that may help you burn fat.
- This formula is all natural.
- Ultimate ThermoFit will cause the need to urinate frequently because of the diuretics in the formula.
- Water weight loss is temporary. Fat loss is what it takes to see long term results.
- All natural does not mean safe. You may experience side effects such as insomnia, headaches, and irritability.
- We do not see evidence of a money back guarantee for this product.
- There are no free trials of this supplement.
Conclusion on Ultimate ThermofitUltimate ThermoFit seems at first glance like it could be what you need to reach your weight loss goals. After factoring in the ingredients will generally only promote weight loss through causing you to release excess water, which may even cause dehydration, we do not believe this supplement is going to help you lose weight and keep it off. Similar side effects have been reported with Intramax. You need a clinically proven safe and effective fat burner or appetite suppressant in conjunction with balanced diet and exercise to reach those goals.

Ultimate ThermoFit Scientific Abstracts:
Insufficient intake of chromium can lead to symptoms similar to that of diabetes or cardiovascular disease. A supplemental dosage of chromium administered to individuals with impaired glucose tolerance results in improved blood glucose, lipid, and insulin levels. Chromium has also shown itself to be useful in improving lean body mass in humans. 
To observe the effects of obesity groups of mice were given a high-fat diet including RK. RK prevented high-fat diet elevations in the body weight of the mice and the weights of their liver and visceral adipose tissues. RK had also reduced weights as well as hepatic triacylglycerol content following their increase due to the high-fat diet. Raspberry ketones had also greatly increased norepinephrine-induced lipolysis. In conclusion, RK stops (as well as improves) obesity and fatty liver. These outcomes seem to derive from the action of RK in changing the lipid metabolism and increasing norepinephrine-induced lipolysis in white adipocytes. 
When compared to baseline, there had been a decrease in insulin and fasting glucose levels after the 30 day treatment period (both p < 0.02). There had also been a reduction in total cholesterol (p = 0.03), in addition to moderately substantial reductions in LDL-cholesterol as well as a ratio of cumulative cholesterol to HDL-cholesterol (p = 0.051 for both). When compared to baseline, participants given acai ameliorated the postprandial rise in plasma glucose succeeding standardized meals, noted as the area under the curve (p = 0.047). There had been no effect on blood pressure. In conclusion, consumption of acai fruit had reduced levels of specific markers of metabolic disease risk in obese and overweight adults, which would indicate that further studies should be carried out. 
Green Tea Leaf Extract
When ingested long-term, tea catechins can be helpful in a fight against high-fat-diet-induced obesity, as well as type 2 diabetes. It could also be a tool to reduce the risk of coronary disease. More studies that follow international standards are needed to be carried out to monitor the clinical and pharmacological effects of green tea to clarify its mechanisms of action. 
Gymnema Leaf Extract
A water-soluble extract of Gymnema sylvestre (GS4) was given to 27 participants (400 mg/day) with insulin-dependent diabetes mellitus. Insulin requirements had dropped altogether with fasting blood glucose, glycosylated hemoglobin and glycosylated plasma protein levels. At the same time, serum lipids did return to almost their normal levels with the therapy, glycosylated plasma protein levels and glycosylated hemoglobin levels had stayed at a higher level than controls. Participants on insulin therapy displayed no substantial decrease in serum lipids, glycosylated hemoglobin or glycosylated plasma proteins during a 10-12 month checkup. The GS4 study appears to show Gymnema sylvestre to enhance insulin, potentially by regeneration of the residual beta cells in insulin-dependent diabetes mellitus.

We looked into Ultimate ThermoFit ingredients to give you the facts you need to know.
Raspberry ketones were made widely popular by Dr. Oz when he called the substance a “miracle in a bottle”. This chemical is derived from red raspberries and is widely known to be used for weight-loss, obesity treatment, and lean body mass.
What Is It Supposed To Do?
Raspberry ketones are supposed to increase your metabolism by affecting a hormone in your body called adiponectin. Raspberry ketones have a variety of uses in the medical world, including decreasing body fat, decreasing weight, and treating hair loss in men.
In a study done by the Journal of the International Society of Sports Nutrition, raspberry ketones were combined with other herbal supplements to test the effectiveness of their weight-loss claims. In the conclusions, researchers reported, “…administration is a safe and effective adjunct to an eight-week diet and exercise weight-loss program by augmenting improvements in body composition, waist and hip girth.”  However, no study has been performed on raspberry ketones alone that involve humans.
Green Tea Extract
Green tea extract is made from the leaves of the Camellia sinesis plant. It has many uses and can come in many different forms, including beverage, extract, tea bags, candy, and ointment.
What Is It Supposed To Do?
The main chemical that creates the benefits of green tea extract is polyphenols. This substance may help prevent joint degeneration and decrease swelling. Green tea extract also contains caffeine, which is the key factor for its ability to improve mental awareness.
According to the University of Maryland’s Medical Center, “Clinical studies suggest that green tea extract may boost metabolism and help burn fat.”  Additionally, the center reported that, “One study found that the combination of green tea and caffeine improved weight-loss and maintenance in people who were overweight and moderately obese.”
Guarana extract, named after the Guarani tribe in the Amazon, is derived from the plant and created through its seeds. It is commonly found in weight-loss supplements as a stimulant and is said to help treat fatigue.
What Is It Supposed To Do?
The main chemical found in guarana extract is caffeine and other chemicals similar to caffeine. It is thought that these chemicals work in the central nervous system and help stimulate the heart, perhaps helping you lose weight.
In a study published in the International Journal of Sports Nutrition and Exercise Metabolism, researchers noted there was no evidence or scientific findings supporting the extract’s weight-loss capability.
Acai berry derives from the acai palm tree. This berry is known for its rich antioxidants and possible weight-loss capabilities. Acai berry is used in many forms for beauty products, foods, therapies, and more.
What Is It Supposed To Do?
Acai berries have plenty of nutrients that may help aid in a healthy diet. The fruit also contains fiber and heart healthy fats, which are good for digestion. Some weight-loss companies claim acai berries may help you lose more.
According to the National Center for Complementary and Alternative Medicine, “No independent studies have been published in peer-reviewed journals that substantiate claims that acai supplements alone promote rapid weight-loss.”
When taking a closer look at weight-loss supplements that work best for shedding off pounds, Leptigen came across as a unique product with four ingredients clinically shown to help the metabolism run at a faster pace.
