Fit Affinity Fat Burner is a weight-loss supplement aimed directly at women, and it comes in a clear bottle with pretty pink and black pills. They are manufactured by Fit Affinity, headquartered in Sydney, Australia, but there is also an offices in Redlands, California. The company opened a Better Business Bureau profile in 2015, but there isn’t a lot of information on the profile, and currently they have a “D” grade and no accreditation.  We’ll discuss that grade further down in the review.

Redlands, CA 92374

Fit Affinity Claims
There are a number of Fit Affinity products: the Fat Burner, a Body Sculptor, and something called Tight Tummy for Her. We’ll be looking specifically at the Fat Burner.
On the main website, they claim that Fit Affinity Fat Burner:
- “[contains] All natural ingredients,
- Assist in metabolising carbohydrates and fats,
- Increase fat burning,
- Boost metabolism,
- Increase energy,
- Reduce fatigue,
- Increase aerobic capacity, (ability to sustain aerobic-type exercise)
- Raises focus & concentration,
- Boosts mood, and
- Also includes citrus extracts for antioxidant benefits.”  (definition added)
They also claim that you don’t need to work out at all to see results and that it will still work quickly for any body type! Another quote from the main website says,
“Expertly formulated using a blend of powerful and naturally derived fat loss ingredients, and proven to increase energy levels, boost metabolism, reduce fatigue, boost mood and optimize fat burning potential, they are sure to give your weight loss goals that all-important push.” 
Fit Affinity also provides customized workout plans available for extra purchase. There are three sample workouts for free, but they are not quite like the ones for purchase, lacking in detail and length.
Their return policy states: “Fit Affinity must receive the item within 30 days of the item’s purchase date. Please note Digital ebook purchases are non refundable, You can contact our service team by writing an e-mail to [email protected] .”

The Science Behind Fit Affinity
The US Food and Drug Administration (FDA) does not regulate dietary supplements, only drugs. As such, supplement labels are prohibited from claiming any research-proven medical or health benefit—this is the function of a drug, in the FDA’s view. The entire issue is problematic, and there’s no shortage of legal action brought against supplement manufacturers by the FDA and the Federal Trade Commission (FTC) on a regular basis.
That said, the company provides little to no research on the actual science behind how they got their formula, and why it magically works without exercise. There are no links on the website, but they do briefly explain the ingredients they used in a little box at the bottom. They make empty claims with nothing to back up their reasoning behind the ingredients.
So let’s take a quick look at the main ones, courtesy of the Mayo Clinic:
While the Mayo Clinic does acknowledge that biotin in the body plays a role in forming fatty acids and glucose, and in metabolizing carbs, there’s no mention of biotin being used as a weight-loss supplement. In fact, the body only needs a little biotin to function normally. 
Vitamin B5, often included in B-complex vitamins. There is no evidence of its effectiveness in much of anything other than its primary purpose in the body, which is to aid in the breakdown of carbs, fats, and proteins. An adult body needs only 4 to 7 g per day. There aren’t any warnings listed for big doses, so while this may or may not improve the effectiveness of Fit Affinity Fat Burner, it’s not likely to harm you, either. 
Green Tea Leaf Powder
Mayo didn’t have a specific article on Green Tea, so I went to WebMD instead. In terms of weight loss itself, the evidence is conflicting but still insufficient. Also insufficient is the evidence for mental alertness. It does seem to have possible effectiveness for both high- and low blood pressure, and is likely effective for high cholesterol. 
Neither Mayo nor WebMD had this one. UK Medical News Today did, though. While capsaicin, the active ingredient, shows a lot of clinical promise in the field of topical pain relief, the jury’s still out on any real promise in terms of weight loss. 
We hear a lot about caffeine, lauded or demonized, praised or panned. In small doses it can do some good; but too much caffeine really is bad for you. Back to the Mayo Clinic: “Up to 400 milligrams (mg) of caffeine a day appears to be safe for most healthy adults. That’s roughly the amount of caffeine in four cups of brewed coffee, 10 cans of cola or two “energy shot” drinks.” 
The caffeine in a daily serving of Fit Affinity Fat Burner is only 130 mg, but that doesn’t count whatever’s in the green tea powder. Still, it doesn’t seem to be an overdose, which is more than can be said about a lot of diet supplements.
Overall, there just isn’t a lot of science to support Fit Affinity’s claims.
Word On The Street About Fit Affinity
Before we tackle customer reviews, let’s look at that Better Business Bureau rating. There were no positive reviews on the BBB profile for Fit Affinity—only three customer complaints. One, from 2015, indicated a customer who had bad side effects and tried to get a refund. The issue was only resolved after the customer informed Fit Affinity they had been reported to the BBB. A full refund was issued at that point.
The other two complaints were from 2017. The first is simply listed as a delivery issue to which the company never responded. The second involved an order never processed, a request for cancellation, and an argument with a customer service representative. That complaint is still open. 
Fit Affinity Fat Burner is sold on Amazon.com as well as on the company website, so there are plenty of honest reviews from customers. Some had a positive reaction to the diet pills, some had no reaction, and others had a terrible reaction. Overall, the reviews leaned positive about 70-30 percent, though 1-star reviews outdid 2- and 3-star by double. Not much middle ground.
“BL” said, “This is a pretty good product for the price. I’ve used more expensive fat burners & this is comparable. No negative side effects, just a boost in energy & metabolism to aid in my weight loss.” 
“Mallory Cornelius” said, “I am one that gets gittery very easily but I can tolerate these pills. Only once in awhile do I feel that way with them. They give me energy for sure which is great for motivation to work out but I have not lost any weight on the pills and I have been taking them for 2 weeks with out working out.” 
“Jo” said, “I bought this and tried it, I followed the directions take two capsule after breakfast, I must say after a few minutes it gave me a burning sensation on my throat, probably due to the cayenne powder, it has a horrible after taste too even if you just swallow the pill with glass of water and then it made me sick, I threw up a few times and still feel sick even after a while. Everyone has different reactions just wanted to share what I experienced, so after that I’m not taking it again.” 
Every supplement affects every individual differently. Gender, age, sometimes race, pre-existing medical conditions, and individual body chemistry—as unique as a fingerprint—can affect how a supplement works on you. That’s why supplements always add that “individual results may vary” disclaimer, and it’s why reviews for a drug or supplement can be all over the spectrum. Only you and your doctor can figure out how it works for you, so always be forthcoming and transparent with your doctor about side effects you experience, as well as if the substance doesn’t seem to be doing anything for you.
The Bottom Line
Is Fit Affinity worth a try?
Insufficient Data to Praise or Pan. “Miracle pill” claims, with little scientific backing, and a full spectrum of customer feedback—combine that with a slightly iffy company reputation, and this one leaves me in the middle. So often a caffeine boost will make you feel revved up for a workout; but it’s hard to determine exactly what works, the pills, the buzz, or just the fact your mind thinks you’re getting something. So while I can’t give it a gold, it’s not in last place, either.
