Skinny Bird Claims
The company website has a very natural and simple feel to it, which also goes along with their company motto: “Beauty Starts From Within.”  The company also claims that there was a 12-week study done on the main ingredient caralluma fimbriata, and that supplement helped the participants in the study lose over 2 inches around the waist during the 9 week study. The recommended usage for the diet pill is, “Take 1 vegan capsule, up to 3 times daily, ideally 30 min before your meal to prevent overeating.” 
The company claims to target four main areas of weight loss with the specific ingredients. “Caralluma fimbriata helps curb appetite by working directly with the appetite control center of your brain. 5-HTP supports serotonin production to help address stress eating. Green tea extract boosts metabolism to help burn fat. Chromium normalizes the utilization of blood sugar in your body and helps reduce cravings. Together, our targeted SMAC program, in vegan form for the most natural support, will help you to look and feel your best.” 
When looking into their FAQ’s and refund information, it was under par being only 30 days. For one thing, you can’t even try the product out to get a full refund.

The Science (or Lack Thereof) Behind Skinny Bird
They make a point to highlight their clinical study on the website as one of the reasons why this product has been said to work for weight loss. The main ingredient they highlight is caralluma fimbriata. What exactly is this ingredient? HUM Nutrition claims it works for appetite control, thus making you feel fuller for longer periods of time. It is a type of edible cactus that is grown and native to India. Its main uses are for weight loss, endurance, and suppression of thirst.
According to Healthline,
“A study published in the journal Perspectives in Clinical Research concluded that more research is needed before C. fimbriata extract can be recommended as an anti-obesity drug.” 
In the controlled study, there were 89 patients who volunteered for 12 weeks to go through with the study. Some of the volunteers were given a capsule with caralluma fimbriata and others were given a placebo pill. According to the study, “Patients were evaluated clinically and biochemically at 4, 8, and 12 weeks for anthropometric measurements, appetite, biochemical investigations, and other safety parameters.”  “A commercially available extract of C. fimbriata in an oral dose of 1 g/day claimed to have anti-obesity effect failed to yield any positive results on anthropometry and appetite in overweight and obese individuals beyond placebo.” The results were a let down after 12 weeks time, and this gives HUM Nutrition’s study and claims about C. Fimbriata shaky ground to walk upon.
There is more than just one study done, however, on the effectiveness or lack thereof of C. Fimbriata on the body. There was another study done about the ingredient and its ability to help ease hyperphagic appetite behavior in children and adolescents with eating troubles. The condition, better known as Prader Willi syndrome, can lead to excessive consumption of food if left untreated. The study evaluated participants over a 10-week time frame and the results were quite different from the study above. The results, “We demonstrate that an extract of the Indian cactus succulent Caralluma fimbriata eases hyperphagic appetite behavior within a cohort of children and adolescents with PWS without notable adverse effects. The outcomes of this study will have a potential positive impact on PWS management.” 
Regarding 5-HTP, there is possible evidence that the claims made by HUM Nutrition are true. The chemical 5-HTP does play a role in producing serotonin to elevate your mood.
According to the University of Maryland,
“5-hydroxytryptophan (5-HTP) is a chemical that the body makes from tryptophan (an essential amino acid that you get from food). After tryptophan is converted into 5-HTP, the chemical is changed into another chemical called serotonin (a neurotransmitter that relays signals between brain cells).” 
This serotonin is responsible for getting your mood right, which helps when you are trying to lose weight.
Regarding green tea extract, there has been word of this ingredient helping to give your metabolism a slight boost. According to a study done by Adrian Hodgson called, “The Effect of Green Tea Extract on Fat Oxidation,” he said, “There is increasing interest in the potential role of green tea extract (GTE) in fat metabolism and its influence on health and exercise performance. A number of studies have observed positive effects of GTE on fat metabolism at rest and during exercise, following both shorter and longer term intake. However, overall, the literature is inconclusive.” 
When the study was all said and done, the results were inconsistent. He said that green tea extract can have an impact on an increase in fat oxidation at a resting level, but that the results have not been consistent overall.
Their final claim about chromium is also interesting because it has been proven to improve insulin levels and glucose levels. In a study done by the Diabetes Journal, elevated levels of taking a chromium supplement proved to be effective in lowering insulin and glucose levels. The subjects being studied all had type 2 diabetes, and they were either given a placebo pill or a chromium supplement.
According to the results,
“Fasting and 2-h insulin values decreased significantly in both groups receiving supplemental chromium after 2 and 4 months. Plasma total cholesterol also decreased after 4 months in the subjects receiving 19.2 μmol/day Cr. These data demonstrate that supplemental chromium had significant beneficial effects on HbA1c, glucose, insulin, and cholesterol variables in subjects with type 2 diabetes.” 
Word On The Street About Skinny Bird
I get all the feels when thinking about weight loss, success, and feeling your best. Does this supplement really work like it says it is going to work? Some of the ingredients were proven effective as shown above, but that does not mean it will work for anyone and everyone (including the birds). Obviously paying attention to what you are eating daily will be a great deal of help for weight loss too. So did people see this product working for them? Lets see how people reviewed the Skinny Bird diet supplement.
Marina B. (5.20.17, 5 star) said,
“This stuff worked for me, really well. So well that I have to sometimes skip a dose because I want my appetite back. It can get a little intense at times, but that may also be because I tend to consume a lot of caffeine. But taking this definitely helps me keep off the few pounds that I usually struggle to keep off. Super happy with this product.” 
Trcay (8.31.2017, 1 star) said,
“What does this claim to do?… nothing perhaps?. Don't bother.” 
The Bottom Line- Is Skinny Bird Worth A Try?
Insufficient Data. Overall there were mixed reviews on whether this supplement actually helped with overall weight loss in general. Some people loved it, others hated it and claimed it gave them headaches and made them feel sick. You really never know how your body will react to a supplement like this, so it is important to know the facts beforehand. Some of the studies lined up, while others did not regarding the claims being made by HUM Nutrition. While the website is clean and the products are enticing, they might not be as effective as they are made out to be.
