NV is the newest fat burner on the block. According to the claim, the product can help you to lose weight quickly. Onetime Playboy playment, Holly Madison said NV diet pills have helped her to drop one jean size in just two weeks! I find this particularly amusing. Not too long ago, the producer of “Peepshows” told Holly that she needed to lose weight. She refused, and in an interview with Radar she said, “I don’t think I need to lose weight.. I always thought I looked fine.” In addition, she also told magazine Life & Style, “I’d rather be overweight and curvy than super thin with no curve.”
Now, she used NV to shed off the extra pounds. She told Shape:
“These days, I’m slim and fit, and I still have the fabuolous curves I’ve always loved!”.
The thing is, I am not sure if you should take her advice. Holly Madison is recruited to become to spokeperson for NV diet pills. In other words, she is paid to say good things about the NV diet pills. You really can’t tell if the endorsement reflects her honest opinions. Even if the product actually works for her, the testimonial is entirely anedoctal, and it’s no substitute for real science. If you look closely on the official website of NV diet pills, you will see this tiny statement: “Holly’s result not typical.”
That said, we should not discount the product just because it’s celebrity-endorsed.
Let’s take a closer look of the list of ingredients of this formula:
#1. The Weight Loss Complex– contains 400 mg of Mangosteen and Indian Sphaeranthus. The Mangosteen exhibits possible anti-inflammatory properties, and may be beneficial to skin infection, dysentery or urinary tract infections. (source)
Indian Sphaeranthus is widely used in Ayurvedic medicine to sure various ailments. Early studies show that the herbal medicine can be used as laxative and tonic. It may also helps to increase appetite, enriches the blood, lessens inflammation, cools the brain and so on (source). Note that most of the studies on Indian Sphaeranthus are conducted on mice, not human! You can’t tell how the results can translate to human. Furthermore, there’s little information recarding the clinical properties and toxicity of the herb.
In addition, the effect of Mangosteen and Indian Sphaeranthus on weight loss has not been clearly demonstrated at this point.
#2. NV Superfruit complex– it contains the following ingredients:
Caffeine: it can help to curb appetite, and it exhibits mild thermogenic effects (source). Because of the benefits, caffeine is used in many fat-burning supplements. The thing is, the exact amount of caffeine inside NV diet pills is not disclosed. Note that excessive caffeine consumption can result in jittery, insomnia, nausea, increased blood pressure and pulse. This can be dangerous, as many of us do not know we have high blood pressure!
In case you are interested, there’s also a caffeine-free version of NV diet pills.
Cranberry extract: cranberry is commonly used in prevention and treatment for urinary tract infection. Few studies show that cranberry extract have shown positive activity as anti-cancer agents in-vitro (see here and here). There’s no evidence of any weight loss effect.
Other ingredients are: Bilberry, Litchi, Tumeric, Tumeric, Grape extract, Pomegranate, and Goji. I am not going to bore you with all the technical jargon. Suffice to say, all these Superfruit agents may be beneficial to your overall health, but there’s no evidence exits that any of these can result in effective weight loss. In addition, the label of NV diet pills contains proprietary blend. The exact amount of ingredients is not disclosed. In other words, you can’t tell if the supplements contain enough active ingredients!
Other problems of NV diet pills: according to the claims, “NV’s core formula is backed by two clinical studies that demonstrate its incredible weight-loss power.”
“In two clinical studies, obese subjects (BMI > 30) consuming two key ingredients in NV lost on average significantly more weight (5.1 lbs and 4.0 lbs) vs. placebo (2.2 lbs and 1.2 lbs) and reduced waist circumference (1.6″ and 1.7″) vs. placebo (0.1″ and 0.3″) in just 2 weeks.”
I could’t find the so called “clinical studies” on official website of NV diet pills. It doesn’t seem to be published anywhere online.
Besides, the following questions remained unanswered:
#1. Are the studies performed on human or rats? What’s the sample size?
#2. Are the studies in-house or peer-reviewed?
It should be noted that the “obese subjects” in the studies consumed 2000 KCAL/day along with mild exercise. That, could be the reasons for weight loss.
NV appears to be an overhyped product with little hype. There’s little evidence to support the claims, and there’s nothing revolutionary inside the formula to justify the high price ($39.95 per bottle). Save your money. Instead, stick to smart diet and regular exercise regime. You will be able to drop jean size within weeks – without NV diet pills. I
