There are numerous ways to lose weight but one of the most significant is actually keeping your appetite under control. Now, the best solution is not to starve yourself but rather to add a formula to your routine that can regulate your appetite and cravings. This review will focus on Slendesta, a popular natural supplement that is said to do extraordinary things.
Coming from the well-established brand Kemin Industries, this patented extract claims to suppress appetite and cravings, leading to an overall increase in calorie deficits and weight loss. The manufacturers even state that Slendesta reduces waist and hip measurements and boosts energy. And the best part is that these results are supposedly achieved naturally, with no stimulants, hormones, or synthetic ingredients.
Can Slendesta really provide these benefits? Just read on and find out everything you need to know about this dietary supplement!
How Does Slendesta Work?
First of all, Slendesta is a form of protein found in potatoes and is known as the proteinase inhibitor II (1) (2). The main purpose of this protein is to stimulate the natural release of cholecystokinin (CCK), the primary trigger that tells your body if you're full or not (3) (4). This way Slendesta manipulates your appetite senses, promoting satiety and a lower desire for food. Dieting and exercising can be very exhausting, luckily Slendesta is also said to boost energy levels giving users the needed edge to push through the day (5) (6).
We have to give credit where credit is due. Slendesta does have a properly designed ingredients label with all the necessary information printed on the product. All Slendesta components are also manufactured in GMP-tested facilitates and are free from GMO’s, MSG, pesticides, or any other controversial substances.
Now as far as ingredients go, there is only one active ingredient which is Potato Protein Extract (Proteinase Inhibitors II). Other inactive ingredients include purified water, Microcrystalline cellulose, Magnesium stearate, and Titanium dioxide.
The Science Behind Slendesta
Kemin Industries, the company behind Slendesta, states that they concluded multiple scientific studies done on more than 500 participants. This research claims that Slendesta is not only safe but also manages to significantly impact the weight loss progress of all tested participants (7) (8). However, here we face a couple of problems.
The first one is the research done by EFSA (European Food Safety Authority), similar to the FDA. They have fully inspected and reviewed Slendesta and Potato Protein Extract, concluding that they did not find any relationship between Slendesta and reduction of body weight (9). Considering the fact that EFSA is an unbiased group that has no benefit from the Slendesta sales, we can see why their results carry more weight (10) (11).
The second problem is in the Kemin Industries research. Their studies are mostly based on animals and limited human research. Also, the human study did not consider each individual’s diet and exercise plan, meaning that these participants may have simply applied a calorie deficit followed by a structured workout plan. This way, participants truly lost weight but most likely not because of Slendesta.
Slendesta Side Effects
Before we discuss the possible side effects that may arise from the use of Slendesta, we need to mention a few safety warnings first.
It is highly recommended that you consult your doctor or physician before using Slendesta. Individuals who are under the legal age of 18, and pregnant and breastfeeding women, should not use Slendesta.
And finally, Slendesta is actually found to be a fairly safe supplement that most likely won’t induce any major side effects. However, some users might experience mild negative effects such as gut and digestion problems.
How to Use Slendesta
As stated by the manufacturers, the way you use Slendesta is the crucial part that leads to results. It is recommended that you take only one capsule of Slendesta with a full glass of water approximately one hour before the two largest meals of the day. An additional capsule may be consumed if necessary. The standard dose is said to provide you with up to three hours of appetite control.
You can purchase Slendesta from the official Kemin Industries website, or through various online dealers such as Amazon and eBay. The price for a month's supply is $22.35, which averages out to around 74 cents per day. Depending on where you purchase Slendesta, you might not receive a money back guarantee.
Is Slendesta a Scam?
Slendesta might give the impression of a scam, however, it is definitely not one. Kemin Industries is actually a genuine brand that was founded way back in 1961. It even has a great Better Business Bureau score. The extraordinary Slendesta claims and low price might leave you surprised, but you shouldn’t be since we saw that this product not only lacks serious scientific research, but ia also potentially ineffective.
What Do Users Say?
Unfortunately, most user reviews are negative. Most users did not receive any weight loss benefits what so ever and the majority even stated that Slendesta did not impact their appetite. Numerous customers were also frustrated since they didn’t feel any difference at all after they used Slendesta. But, on the positive side, no dangerous and serious side effects where mentioned.
Overall, we like the fact that Slendesta comes from a reputable and established brand. The product also contains a properly designed product label, all-natural ingredients, and loads of other safety benefits. However, this supplement is missing some serious scientific evidence of effectiveness. The studies conducted by the manufacturers are likely unbiased and prove absolutely nothing. On the other hand, EFSA did a better job with the research, actually coming up with the true properties of Slendesta and Potato Protein Extract. Combining the negative results concluded in the research, negative user experiences, and money back guarantee issues, Slendesta is not the best dietary option. There are better weight loss supplements available on the market today, so don’t waste your time and money.
