Three Best Fat Burners: Reviews

1. Leanbean– Best Overall Fat Burner

What is Leanbean?

Leanbean is a fat burner built around a hefty daily dose of glucomannan: A clinically-proven 3g daily dose to be exact.

With glucomannan at its core, Leanbean utilizes a proven appetite suppressant.

As a result, it can credibly claim to curb your cravings and help you eat less at mealtimes, meaning that your body will store less fat in the long run.

Leanbean also contains a further 10 natural ingredients…

The objective of which is to support fat metabolism, target common vitamin deficiencies and to provide a thermogenic boost. That’s several concurrent methods of action to help you enhance your weight loss results.

And whilst the price point for this fat burner is a bit on the premium side there are multibuy discounts available when you buy from the official website.

The Leanbean fat burner has also gained fans around the world and is the favourite of professional athletes like surfer Bree Kleintop.

Check out reviews on their site and on any of hundreds of other sites, and you’ll see the same theme pop up again and again: Leanbean is a fat burner that works.

Note: This supplement isn’t available on Amazon – a decision likely made to protect against fakes.

Key Ingredients

Glucomannan 

This natural dietary fiber is a clinically-proven appetite suppressant. When ingested it expands in your stomach and helps you feel the need to eat less. More importantly it has been approved by the EFSA for weight loss in the context of an energy-restricted diet.

Garcinia Cambogia

Another natural extract, this time from the rind of a small pumpkin-like fruit. One of the components – hydroxycitric acid – has strong links to weight loss, especially with regard to appetite suppression.

Choline

A metabolic booster that ramps up your body’s fat metabolism, helping it to transport, store, and break down fat.

Leanbean Pros:

  • Premium fat burning formula.
  • Includes ingredients/doses with regulatory backing for health claims.
  • Curbs cravings & boosts metabolism.
  • Positive reviews across the board.
  • Bulk discounts are available.

2. Powher Fat Burner – Best Fat Burner for Women

What is the Powher Fat Burner for Women?

The fat burner marketplace is dominated by male-targeted products…

Head to the websites for most fat burners and you’ll see a recurring theme of macho branding and stimulant filled supplements.

Now, there’s nothing wrong with that, but let’s be honest – as a woman looking to lose weight, you’re probably wanting something less masculine.

If that’s the case, Powher is built with you in mind.

This fat burner is tailored to the female physiology, delivering a refined blend of glucomannan, vitamins, and caffeine to help you reach your weight loss goals.

This pill also helps you supplement your iron intake. The reason being that Iron deficiency occurs in women more than men and can lead to lethargy and a lack of energy.

The Powher Fat Burner for Women also stacks well with two other supplements in the Powher range: A pre-workout and sleep supplement work in tandem with this product to help you optimize your body goals.

As a woman looking to lose weight, what more can you ask for?

Key Ingredients

Glucomannan

Powher includes the same daily dose as Leanbean – 3x1g servings per day. The same amount noted by health safety authorities as clinically-proven for weight loss.

Natural caffeine

Caffeine is incredibly powerful. It’s linked to boosted endurance, motivation, focus, and energy levels: Four key things you need when you’re bringing the thunder at the gym.

When you can work out harder and for longer, you’re more likely to achieve a calorie deficit, meaning you’ll burn more than you take in, and lose weight as a result.

Iron

Women are more prone to be deficient in iron than men, we’re sad to say. Powher looks to prevent this energy-sapping deficiency by pumping up your iron levels through daily supplementation.

Powher Pros:

  • Uses super-fiber glucomannan and in sufficient doses too.
  • Includes safe amounts of caffeine to boost fat burning.
  • Tailored specifically for female physiology.
  • Stack with other Powher supplements to help you meet your lifestyle objectives.
  • Healthy discounts available when you buy multiple packs.

3. littledrops – Natural CBD Supplement to Curb Cravings 

What are littledrops?

If you’re expecting another capsule-based supplement packed with natural ingredients, vitamins, and minerals, take a deep breath now.

Because the third product in this guide is nothing of the sort.

It’s a CBD gummy. Yep, gummy as in the sweet. And CBD as in the popular cannabis extract linked with all sorts of positive effects around sleep, stress, and anxiety.

And, linked by an increasing amount of research to appetite suppression.

Let’s face it: A lot of weight loss supplements, fat burners especially, have a certain aesthetic. They encourage an active lifestyle, there’s loads of imagery of people being super-active on their website…

That’s great, but not everyone is looking for exercise motivation.

Some people are looking for alternative remedies to help them relax and enjoy a more restful night’s sleep.

And guess what?

Both of those things are linked to reductions in over-eating. And reductions in over-eating mean fewer calories consumed, and less likelihood of gaining weight.

So, while a CBD gummy is probably the last thing you expected to see in this list, products like littledrops are becoming more popular with those looking to burn fat and lose weight.

Key Ingredients

20mg broad-spectrum CBD extract

Each littledrops gummy contains 20mg broad-spectrum CBD, from US-grown hemp harvests This is a generous dose but not too high to overwhelm new users. If you want more than 20mg per dose then you can up the dose to a maximum of 2 gummies daily.

Pros:

  • A nice alternative to all the fat burner supplements on the market.
  • Flexible dosing means that you get to control how much you take.
  • An increasing body of research links CBD with reductions in appetite.
  • May help to reduce stress and anxiety, and to give you a better sleep. All of which may help reduce overeating.

Buying A Fat Burner Supplement: Five Key Things to Consider

Health Claims

By definition, fat burners claim to help you burn fat and as a result lose weight.

The point of taking such supplements is that you’ll see greater reductions in bodyweight overtime than if you weren’t taking anything at all. The problem is that the market is awash with ineffective diet pills all promising great results.

So how do you protect yourself from making a bad purchase?

Here’s a useful checklist:

  • Watch out for fat burners that are vague about dosages
  • Avoid supplements that claim to work like prescription drugs
  • Be aware that very few natural ingredients come with valid claims
  • Ingredients like Glucomannan do work but not many products contain the right dose

If you’re looking to assess the efficacy of a certain ingredient, then regulatory bodies like the EFSA are responsible for legally ratifying claims…

A 3g daily dose of glucomannan has been approved for weight loss but only when used in three separate 1 gram servings.

82.5mg dose of choline has been shown to support normal fat metabolism.

What Are The Best Fat Burner Ingredients?

Hundreds of ingredients have links to fat loss. These claims sit on a spectrum of clinically proven to wildly speculative. When choosing a fat burner, you want to be sure that its ingredients fit firmly into the first category.

AND this ties into what we said before. Some of the more unscrupulous manufacturers just want to sell as much product as possible, so they’ll prioritise cheaper ingredients over effective ones.

And even if they do include the best fat burning ingredients, it’s very unlikely they’ll include them in large enough doses to work.

Here are a few of the better supported fat burner ingredients:

  • Glucomannan (3g per day)
  • Choline (82.5mg per day)
  • Vitamin B
  • L-Carnitine
  • Iron

Doses

Understanding whether a fat burner ingredient has any credible science behind it is the first step. The next step is understanding whether the dose in question is enough to cause the desired effect.

Take glucomannan, for example. This dietary fibre is extracted from the root of the konjac plant. It expands when it absorbs water and is a popular appetite suppressant as a result. You’ll find glucomannan in the formulas of many fat burners.

But to be effective, you need a daily dose of 3g glucomannan. And this 3g needs to be split out into three 1g doses. This is set out in the official published opinion of the European Health Safety Authority – experts in the field of nutrition and food safety.

The reverse is true for other ingredients: Sometimes there’s too much included in a daily dose, and the amount can trigger negative side effects.

90mg of caffeine is the amount generally required to have a physiological effect, but many manufacturers go overboard and include up to three times that amount.

And here’s why…

The logic is that by including large amounts of stimulants you will sweat more during exercise and burn more fat as a result. Sounds great right?

In reality there is no evidence that higher levels of caffeine will help you lose more weight, and moreover this stimulant can be dangerous if used in too large amounts.

Price

Some fat burners carry a higher price tag than others. Some of these are worth the extra money, and some, not so much. As the buyer, it’s up to you to weigh up the cost versus the credibility of the claims to see whether you’re happy paying the asking price.

As we’ve mentioned previously a larger dose of certain ingredients is critical to a product’s results, so you might find the better products are not cheap.

One thing to be aware of is that many supplement manufacturers offer multibuy discounts which present a real opportunity to save a lot of money. It’s not unusual to get a month free when you buy three month’s worth, for example.

Also, Amazon lets you subscribe to some supplements, meaning you get a discount if you agree to have it delivered automatically each month. For a supplement you’re planning to take for a long time, this can add up to some good savings.

Reviews

Supplement manufacturers have pretty free reign with what they can say on their websites. Because the FDA does not monitor supplements, there are less strict requirements on the claims that can be made.

With this in mind, be aware that you’re only reading one side of the story. To get the other side, you need to look to third party reviews. Places like Facebook, Amazon, Google, etc.

Try to find what real people are saying about the fat burner you’re thinking of trying. Do frequent themes pop up, either positive or negative? Are people broadly happy with the results, or does consensus seem to be that the product isn’t worthwhile?

Gauging popular opinion on products you’re thinking of trying is a great way to give yourself the best chance of getting something good.

How Do Fat Burners Work?

Fat burners rely on being integrated into a healthy lifestyle to have a chance of working.

They’re designed to supplement results you’d see from a healthy diet not to burn fat regardless of what you’re eating.

If you’re willing to make lifestyle changes conducive to weight loss, fat burners have a good chance of working for you. These can be big or small changes.

It’s important to know however that “Fat burner” is a broad umbrella term . It covers a number of supplements designed to help you lose weight and includes metabolism boosters, appetite suppressants, and thermogenics.

Some products combine two or more of these mechanisms to achieve their claims, too.

Knowing what each term means is a key step in choosing a fat burner. As is identifying a product that uses only the mechanisms you’re comfortable with.

So here’s a quick rundown of the main ones…

Metabolism boosters:

  • Stimulate your body’s natural metabolic processes
  • Streamline the processes by which fats are processed and stored by the body
  • Aid the breakdown of fats as fuel rather than storage in fatty deposits

Appetite suppressants:

  • Reduce how many calories you take in
  • Reduce the physical amount of food you eat, meaning fewer calories entering your body
  • Or, reduce the number of calories absorbed from the food you eat

Thermogenics:

  • Raise your body temperature
  • Increase the number of calories that are burned at rest.
  • Help your body to burn more calories during the day exercise

Do Fat Burners Have Side Effects?

Some ingredients found in fat burners do have the potential to lead to side effects. However, most fat burners are formulated so that taking them as directed will not trigger these effects.

These are the types of side effects you might see on a fat burner label –

  • Gastrointestinal discomfort
  • Diarrhea
  • Jitters
  • Dehydration
  • Nausea
  • Restlessness
  • Sweating

Used as directed, supplements are unlikely to trigger such effects. There is a risk in combining supplements, though.

Taking glucomannan as an example: If you have 3g per day from one supplement, that’s great. That’s clinically proven to be effective.

If you have 3g per day from one supplement and another 3g from another supplement, though, that’s 6g total per day. Way above what’s necessary, and closer to what’s linked with gastrointestinal upset.

Be careful if you decide to mix supplements. Generally, we’d recommend just taking one, unless you take ones that are specifically designed to stack with each other.

Also be observant about how much caffeine your fat burner includes. As we said earlier, some supplements include caffeine doses above what you may be comfortable with, and too much of this ingredient can trigger anxiety, jitters, and other undesirable side effects.

If you’re unsure about side effects, chat with your doctor. They’ll be able to offer solid advice.
