4. PhenQ - Best Appetite Suppressing Fat Burner 

Brand Overview  

PhenQ is a scientifically backed weight loss solution that offers an appetite suppressant and fat burner wrapped into one.  

This 100% natural dietary supplement contains only 6 ingredients, but all have scientific research supporting PhenQ’s weight-loss claims.  

The main ingredient is a unique, trademarked blend called α-Lacys Reset®, which fires up your metabolism to burn both fat and calories. Combined with powerful appetite suppressing and energy-yielding ingredients, PhenQ offers the total weight loss package.  

PhenQ was created to help women lose weight, but it has proven to be effective and safe for men as well. 

Oh, and as a bonus, with PhenQ you only have to take two capsules per day. That’s much less than with most diet pills on the market!  


α-Lacys Reset®  

PhenQ secret ingredient and one of the main reasons why PhenQ has such a loyal fan base.  

Several clinical studies tested the stuff and found it decreases body weight and fat while increasing muscle mass. And with muscles burning more calories than fat, you can see how α-Lacys Reset® is a real game changer!  

Capsimax Powder  

This fat-busting blend consists of capsicum, piperine, caffeine, and niacin (vitamin B3). Research suggests these ingredients have strong thermogenic properties. By raising your body heat you burn fat quicker.  

Chromium Picolinate  

This essential mineral is known to help keep your blood sugar levels under control. Some studies have found that this can help you control what you eat by curbing your cravings for both carbs and sugar.   


Caffeine is the ideal ingredient to help you lose weight because it affects your body in several ways at once. Now we all know the energy boost you get from your morning cup of coffee. But that’s not all.  

Research has shown it fires up your body’s temperature (thermogenesis) to increase calorie burn, while also reducing your appetite to curb those snack cravings. Now that’s a winning combination!

Key Factors To Consider When Buying An Appetite Suppressant


Browse appetite suppressants on Amazon, and you'll see names like apple cider vinegar, caffeine, garcinia Cambogia, l-carnitine and more popping out. Many ingredients are linked with appetite suppressant effects, but it's essential to do your research and understand what each ingredient is and why it's included in a product.

Some ingredients are more effective than others. Glucomannan, for example, is clinically proven by food safety authorities for weight loss in specific contexts. This fiber expands in your digestive system, promoting feelings of fullness and helping you to eat less. 

Ingredients like l-carnitine and white kidney bean extract have also received tentative support from food safety authorities. The research around ingredients and their effects is ever-expanding, meaning that claims change over time. This is why it’s important to do research and keep abreast of developments.

It also explains why fad ingredients sometimes make an appearance in supplements: These ingredients may not have much (or any) impact, but manufacturers know that including them might lead to more sales. 

Try to understand whether the ingredients work, and what the science says about their effectiveness.


Understanding the claims made about an ingredient is an integral part of choosing a supplement. Because products in this category aren't regulated by the FDA, it's easier for manufacturers to make bold claims that may or may not be rooted in truth. 

If you’re not familiar, by the way, the FDA are the Food & Drug Administration. They’re a U.S. government agency tasked with assessing the properties and safety of ingredients and substances used in foods and drugs. 

On top of this, other organisations exist outside the U.S., including the European Food Safety Authority (EFSA) and Health Canada. These regulatory bodies can serve as useful reference points when it comes to assessing the legitimacy of specific claims.

With this in mind, carefully check the claims being made. See whether they sound too good to be true (hint: they usually are). Cross-reference the manufacturer claims with published scientific opinion to see whether the claims stand up. And make your decision from there.

Some appetite suppressants are available as prescription medication. In this case, the claims have a much stronger basis because medicines are strictly regulated. 

Prescription or over-the-counter?

Some health conditions require prescription appetite suppressants. A doctor will prescribe these as a means to control a patient's appetite and help them to lose weight in a controlled medical setting.

Unless you are prescribed weight loss medicines like Contrave, Saxenda, or Qsymia by a qualified health professional, they are not safe to take. 

These drugs require medical supervision and usually carry more significant side effect risks than over-the-counter products because of the more potent ingredients involved.

Over-the-counter appetite suppressants are most often in the form of supplements. These products are designed to use various combinations of natural ingredients linked to appetite suppression and weight loss. They are less potent than prescription medicines and carry lower side effect risk. 

Still, because they aren't regulated, consumers need to spend more time understanding the ingredients and evaluating the claims.


Appetite suppressants vary in price, and it's not always a case of getting what you pay for. Some expensive supplements are ineffective, and some cheap ones are surprisingly good. Spend some time looking into other aspects of any products you're looking at to try and get a feel for whether they're worth the money.

Many supplement manufacturers give exclusive discounts on their official websites, so always bear this in mind as a way to maybe save some money. You can subscribe to lots of supplements on Amazon as well - another opportunity to enjoy a discount if you pay monthly.


Supplements are just like any other product: You'll see the same names pop up again and again. Read a few "best appetite suppressant" articles, and you'll see companies like Leanbean, Powher, alli, BurnXT and more.

That these companies are featured so often in 'best of' articles is a good vouch for their quality. It's not definitive, of course, but it's one of many factors worth considering.

Customer Reviews

Of all the factors we've covered so far, this is one of the most important. Customer reviews are a source of real insight into the products you're looking at. Real people with real weight loss needs giving their honest opinion of a product based on the results it's delivered to them - what more could you ask?

We recommend checking out the reviews of any appetite suppressant you're considering. Read a few in detail - high and low ratings - to get a better understanding of what you can expect, and whether other people's expectations were met.


Just including an ingredient in the formula of an appetite suppressant isn't enough to guarantee effectiveness. You need to have the right amount.

When you're looking at the ingredients in products you're interested in, take a look at the daily dosage of each, and cross-reference this with information about the ideal dose. 

With glucomannan, for example. We mentioned earlier that it's clinically proven in specific contexts. This is only true of a daily dose of 3g, split into three separate 1g servings. 

Some supplements echo this in their directions. Others only include 1g of glucomannan per day - an amount that won't have the desired results.


This is paramount. You want the peace of mind that the appetite suppressant you're planning to take isn't harmful, and that it doesn't have any unpleasant side effects.

Manufacturer claims and messaging are an excellent place to start looking, but we recommend reading reviews and checking out published opinions on potential side effects attached to each ingredient. 

While the vast majority of ingredients commonly used in appetite suppressants carry minimal risk of side effects when taken as directed, knowledge is power. Caffeine, for example, is safe and effective in low doses, but can cause severe anxiety at higher doses. This is why researching dosage is just as important as ingredients.

Also, keep your eye out for banned ingredients. In 2004 it became illegal to sell supplements containing ephedra - a naturally-occurring plant extract that is harmful for humans. It was banned after a spate of serious illness and death linked to supplements that contained it.

Do Appetite Suppressants Work for Weight Loss?

Appetite suppressants are a broad category that includes all manner of products, so there's no definitive yes or no answer to this question.

Some appetite suppressant products do work for weight loss. These are the ones that demonstrate the following criteria -

• Ingredients backed by scientific studies showing real links to appetite suppression.

• Daily doses high enough to create the effects shown in scientific studies. Supplements with too little of an ingredient will not be sufficient.

• Clear communication about how much to take, and when to take the supplement.

• Honest expectations set: No supplement should promise to deliver weight loss results without lifestyle changes.

When choosing an appetite suppressant, it's down to you to decide whether it's likely to work for you based on the ingredients and claims, and their alignment with your goals.

Then, when you're taking an appetite suppressant, you need to remain vigilant to see whether it works on an ongoing basis.

There are definitely products in this category - supplements or otherwise - that work. Equipping yourself with information to make an informed decision is the best way to ensure that your appetite suppressant works for you.

Also bear in mind that there are many ways to lose weight. Diets look to change the amount of food you eat and the frequency of meals, with the view to reducing overall caloric intake. Exercise helps, but exercise alone is less effective than you might think. 

The elements of a lifestyle conducive to weight loss will vary between people based on their goals and fitness levels. It’s important to remember that appetite suppressants are designed to bolster weight loss results from such a lifestyle. When they are treated as such, the likelihood of them working for you increases. 

What Is The Best Appetite Suppressant? Over-the-counter Or Prescription?

There are several prescription appetite suppressants, including Contrave, Saxenda, and Qsymia. As medicines, these are regulated by the FDA and are only available when prescribed by a medical professional.

The question of 'best' depends on your needs. If you have a medical condition that requires a prescription appetite suppressant, a prescription is probably best for you. If, however, you are trying to find a natural way to reduce cravings and caloric intake, an over-the-counter product or supplement is probably a better bet.

Prescription drugs should only ever be taken when determined by a professional. These substances are more potent and carry more significant risks of side effects, meaning they are not suitable for casual, unsupervised use.

What Is The Best Natural Ingredient For Appetite Suppression? 

The best natural ingredient for appetite suppression is glucomannan. When you take 3g a day split out into three 1g increments, glucomannan is clinically-proven as effective for weight loss. 

It expands in your digestive system, physically stimulating the nerves in your stomach to simulate feelings of fullness. This means you feel the need to eat less per meal, reducing your overall caloric intake.

How Do I Get The Best Results From An Appetite Suppressant?

Getting the best results from an appetite suppressant comes down to taking the product consistently and as directed. If you are looking to achieve significant weight loss, then making lifestyle adjustments will also be fundamental to success.

This means more regular exercise, lower caloric intake, and other lifestyle changes linked to good health like better sleep and reduced stress. Your total daily energy expenditure (TDEE) should be higher than your daily caloric intake to achieve weight loss, and appetite suppressants are one factor that can contribute to this.

Getting the best results from appetite suppressants does not mean taking a pill and hoping for the best. This will not work. To ensure you see any benefits, you will need to use them consistently alongside wider lifestyle changes.

Check-In With Your Doctor

If you're concerned about your weight or lifestyle, speak with a doctor. They are trained to point you in the right direction, toward a lifestyle that will help with weight loss. They'll be able to advise on whether appetite suppressants are suitable for you and, if so, whether a prescription or over-the-counter option best suits your needs.

Make Wider Lifestyle Changes

As we said, weight loss comes down to keeping your caloric intake below your daily energy expenditure. Safely reducing caloric intake is one way to adjust this balance - eat less, eat lower-calorie food, use appetite suppressants. Increasing daily energy expenditure is another way. This means more frequent exercise, longer workouts, drinking more water, and the use of thermogenics or other fat burner techniques to boost your results.

Keep Your TDEE In Mind

TDEE: Total Daily Energy Expenditure. Keep this at the forefront of your mind when planning lifestyle changes to lose weight. No fat burner or appetite suppressant is going to melt fat away magically. They're all designed to support weight loss, and any manufacturer who claims to offer the magic bullet is not being truthful.

Aim For Consistency

Making lifestyle changes is hard, but keep at it. You'll see more significant results if you run a caloric deficit every day. Incremental changes in lifestyle are more comfortable to implement than a complete overhaul, so bear this in mind. Work out for five more minutes each day at first. Cut out excess sugar from your diet. And remember, building things up gradually will improve your chances of success when compared to trying to change everything at once.

Be Kind To Yourself

The most important thing? Show yourself kindness. Deciding to lose weight and build a healthier lifestyle is a great decision, and it's not easy. If you slip up, don't punish yourself. Enjoy your successes. Acknowledge the improvements you're making, and take time to celebrate them.

With this mindset, you begin to see appetite suppressants as tools to be used to achieve your goals. You start to see workouts as necessary and enjoyable, rather than painful slogs. And you'll begin to have a positive and wholesome experience with greater fitness and more weight loss.

Are Appetite Suppressants Safe? And Do They Come With Side Effects?

Broadly, appetite suppressants are safe. Some ingredients in appetite suppressant supplements are linked with side effects, but in the vast majority of cases, taking a supplement as directed will avoid them.

Prescription appetite suppressants are linked to stronger side effects, which is one of the reasons they require medical supervision. Because these medicines are designed to stop your body ingesting fat, there is a higher likelihood of gastrointestinal issues, especially if you continue to eat high-fat content foods while taking the medications.

We've mentioned glucomannan a couple of times in this article. A daily dose of 3g is clinically-proven for weight loss, as we've said, but it's important to take glucomannan supplements as directed. The ingredient expands on exposure to water, which has led to a small number of incidents of choking when the product was taken with insufficient water. It's crucial to wash supplements down with a glass of water or two, to ensure they reach your stomach correctly.

We’ve mentioned caffeine, too. A safe dose of caffeine is considered to be around 100mg, and anything above this risks triggering side effects like anxiety and gastrointestinal issues. Tolerance varies between people based on physicality, how much coffee you drink, and other factors. If you’re looking at supplements with high doses of caffeine, go steady.

To find out more about side effects for appetite suppressant ingredients, you can take a look at the databank on the Office of Dietary Supplements (ODS) website, or speak with your doctor.


What Are The Best Doses For Weight Loss?

This depends on the ingredient. For glucomannan, it's 3g split into three 1g servings - just like you'll find in Leanbean and Powher.

Other ingredients vary: You can find this information on the ODS website, or on supplement websites.

Would I Benefit From Using Appetite Suppressant Pills?

If you are looking to control cravings and reduce the amount of food you eat with the view to lose weight, and you're willing to make other lifestyle changes on top of taking a supplement, then yes. Appetite suppressant pills are just one small weapon in your weight-loss arsenal.

How Much Should Appetite Suppressants Cost?

There's no fixed answer to this question, unfortunately. The price point of supplements on the market ranges from $10 to over $100, and you don't always get what you pay for.

Research is vital here. You'll get a feel for which prices feel right and which feel over-the-odds. You'll sometimes find supplements that are too cheap to be true, as well. 

Expect to pay somewhere between $40-70 for a month's supply of a good-quality supplement. And look out for multibuy discounts on official websites - these are a great way to save money.

Will I Actually Lose Weight With An Appetite Suppressant?

If you take appetite suppressants as part of broader lifestyle changes, then yes, you can lose weight with this category of supplement. As we've said: The goal of appetite suppressants is to help you curb cravings and reduce caloric intake, and reducing caloric intake is just one half of the TDEE equation.

Do Appetite Suppressants Work Without Exercise?

They might make you feel less hungry without exercise, but it's unlikely they'll lead to noticeable weight loss without it, for the reasons we've covered.

Be very wary of any supplement that promises results without exercise or lifestyle changes.


With obesity reaching epidemic levels, appetite suppressants have become increasingly popular. In this category you'll find natural supplements containing dietary fiber, prescription weight loss drugs, and even novel products like CBD, all of which claim to support reduced cravings and food intake.

Which one you choose is down to your personal circumstances. If you’re very concerned about your weight and think you may have a medical need for prescription medication, then prescription appetite suppressants may be a better fit. A qualified medical professional can help with this.

Alternatively if you're just looking to lose a sensible amount of weight as part of a healthy new lifestyle then a natural supplement like Leanbean might be a good choice for you.
