Quick Summary


Fat & Carb blockers are a group of supplements and food components that, put simply, block carbs and fats from being absorbed in the body. Lipozene, Glucomannan (Konjac root), Chitosan, Xenical (Orlistat), Benefiber, Skinny pill etc. fall into this group of fat blockers and claim to be fast acting products.

Currently, Wayt-less, PhenQ and Instant Knockout are leading the race of best fat blockers in the market.

Where to buy Glucomannan/konjac fiber supplements?

The best Glucomannan/fiber supplements in the market are Instant Knockout, & PhenQ, which are better than most run-of-the-mill fiber supplements available on ecommerce sites like Amazon.com, eBay etc. which would be second best. However, for consumers looking to intensify weight loss effects of fat blocking supplements, product like Wayt-less might be better option as it combines fat blocker with a carb blocker and appetite suppressant (low dose naltrexone).

Where to buy Chitosan supplements?

Chitosan supplements can be bought on several e-commerce websites like Amazon, eBay, Luckyvitamin.com, Vitaminshoppe.com, GNC etc. NOW Supplements Chitosan 500 mg plus Chromium is one of the best cheap weight management product, available on Amazon.com right now.

What is the best fat blocker on the market?

Alli (Xenical/Orlistat), Wayt-less (Orlistat + Acarbose + Low dose naltrexone), PhenQ are the best fat blockers available in the market right now. While Alli and PhenQ fat blockers are available over the counter, Wayt-less can be had after a quick online consultation and getting a prescription online.

What are best fiber supplements for weight loss?

PhenQ, Instant Knockout, Benefiber are some of the best fiber supplements for weight loss available in the market. Although glucomannan and other soluble fiber supplements are a good alternative, most consumers need to focus on diet based on whole plant foods combined with a multi-ingredient weight loss supplement that has other ingredients besides fiber.

Are there any belly fat burner pills?

Many experts believe that “SPOT” fat reduction is a myth and you have to lose weight throughout your body, to also make you lose weight at the spots you want, like the abdomen area. However, consuming an effective weight loss supplement and combining with belly fat reduction exercises like HIIT and crunches would give you quicker results.

Bottomline on Lipozene (Glucomannan) & Chitosan

Consumers not willing to plan to diet and exercise won’t see much benefits from taking Lipozene, Glucomannan or Chitosan. Trying to include it as a part of some serious weight loss program, exercise, and diet, may help mildly! Lipozene (glucomannan) works only by one mechanism or line of action :- “appetite suppression” by making stomach full by fiber. Chitosan also works by only one mechanism ie. blocking fat absorption & eliminating it from the gut.

However, appetite suppression and weight loss in general is not that simple. Besides, many users have reported fatigue, weakness and intestinal side effects. Typical Fiber supplements & tablets in the market like Glucomannan/Chitosan or other herbal fat blockers are usually too weak appetite suppressants to deal with complex hormonal dynamics of obesity. Besides, these will make you feel fatigued and weak, because they reduce the calories somehow but do not target your brain chemistry.
In contrast, ingredients in products like Wayt-less(low dose naltrexone) target the “energy giving” hormones and neurotransmitters, thereby causing your brain to think that there is already energy in the body and the brain does not trigger “hunger”

4. Wayt-less

Wayt-less is a powerful appetite suppressant/carbs & fat blocker in one that contains 3 powerful prescription diet pills – Acarbose (Generic Precose®), Orlistat (Generic Xenical®), Low Dose Naltrexone). You can avail a prescription online using Telemedicine.

The custom compound of these three medications creates the perfect atmosphere for weight loss, especially when combined with a reduced-calorie diet and exercise program. Acarbose and orlistat work together by decreasing lipid and carbohydrate digestion; thus, creating a natural caloric deficit and suppression in appetite.

Acarbose, when combined with orlistat, can also diminish the adverse gastrointestinal side effects that come with taking orlistat.

When naltrexone and acarbose are combined, it triggers appetite and craving suppression leading to lower food intake and weight loss. When orlistat is added, this trio of medications becomes the perfect way of fighting obesity and all the symptoms that come with it.

WAYT-less ingredients


With Wayt-less, appetite suppression, carb, and fat digestion can significantly reduce the daily amount of caloric intake without causing the discomfort and lack of energy that is normally associated with calorie-restricted diets.

Jacked Factory’s Burn-Xt thermogenic fat burner is a very popular diet pill, that ranks among Amazon.com’s best selling appetite suppressants. Designed to boost energy and suppress your appetite, it is packed with vital ingredients to increase the metabolism, improve training and increase concentration. However, unlike many other products sold on Amazon & other ecommerce websites and stores like GNC etc, this fat burner has a completely transparent label and you know exactly what’s in it and how much.

Key Features:

Boost metabolism
Boost energy
Appetite suppressant

Fortunately, Jacked Factory Burn XT is packed with the fundamental ingredients that are essential for an effective fat burner. Not only do the ingredients carry thermogenic properties which have the ability to increase the metabolism, but ingredients such as caffeine will help you grind through gruelling workouts when you’re undergoing a calorie deficit.

Although there are various similar products available on Amazon.com, this product has been around for many years now, with a loyal following of repeat customers.

Besides, not all weight loss products sold on Amazon can be trusted, as the marketplace is plagued by fake reviews, thereby compelling FTC to take action against some of the companies promoting their products on Amazon using fake reviews.

Burn-XT ingredients


Overall, it’s a simple yet powerful formulation, which makes Burn-XT one of the best-selling appetite suppressants in the marketplace.

While you can find many similar supplements that share these ingredients, LeanBean is getting huge attention and quickly becoming the top seller.

7. VINTAGE BURN Fat Burner by OldSchoolLabs

One of the top rated fat burner on Amazon.com, Vintage Burn comes with powerful combination of ingredients, although NOT as good as Lean Optimizer.

VINTAGE BURN is a third-party tested weight loss supplement made exclusively with premium ingredients including green coffee bean extract, green tea extract, and raspberry ketones to help burn stubborn belly fat. Zero artificial substances, zero synthetic additives, zero preservatives.

Vintage Burn quickly became one of best selling weight loss supplements on Amazon.com with repeat customers purchasing to support their diet program.

On the positive side, the company doesn’t hide behind a proprietary blend or secret sauce. So many other supplements do this, and it’s annoying. So, kudos to Old School for publishing the details.

OSL Vintage Burn ingredients


Green Coffee Bean Extract, Green Tea Leaf Extract, Raspberry Ketones, Olive Leaf Extract, Caffeine, Bacopa Leaf Extract, Garcinia Fruit Extract, Chrysin, Forskohlii Root Extract. Amounts of each ingredient in this supplement are disclosed on the product label, which is included in the Amazon product images.

OSL HERITAGE: Old School Labs, California; Supplements That Make Sense, 4 Years in the Making. Their team of experts are available by email or social media to answer questions regarding the best way to use a product.

Yes, there are a few side effects that come from the Vintage Burn fat burner. It is the result of the chosen ingredients. For a safer version of this formulation, you might be interested in taking a look at Instant Knockout.

Even though it’s lactose and gluten-free, there have been quite a few reports of users suffering from side effects, like nausea with regular use.

Vintage Burn, like Instant Knockout is also a product targeted towards bodybuilders, athletes and fitness enthusiasts.

Weight loss supplements don’t distinguish between fat and muscle. This means that you may be losing muscle at the same rate you are losing fat.

Muscle burns three times as many calories as fat per pound. It is your best weapon for burning more calories and making future fat loss more difficult.

Vintage Burn is a thermogenic fat burner specifically formulated to preserve muscle to give you real and continuing results. It can also improve your mental focus, mood, and pre-workout energy.


Considering my experience with my own body, Personally i think that a proper fat loss supplementation routine can increase fat loss by about 30 to 50% with little-to-no side effects.

That is, if you can lose 1 pound of fat per week through proper diet and exercise (and you can), you can lose 1.3 to 1.5 pounds of fat per week by adding the right weight loss supplements, appetite suppressants into the mix.

An additional big advantage of taking the right fat loss supplements, especially the more powerful ones like Lean Optimizer or Waytless is they are particularly good for getting rid of that stubborn fat, which is usually belly fat for us guys and hip and thigh fat for girls.

So, although even the best “stack” of fat loss supplements isn’t ground breaking stuff, but I think it’s advantageous for both the lean looking to get really lean and overweight wanting to get lean. Read more on the insider guide to fat burning pills.
