Fat Burners to Buy in 2024

Fat burners are the most popular type of diet pill by far. Most of them contain ingredients that speed up the metabolism.

By speeding up the metabolism in the way they do, fat burning diet pills cause the body to burn calories faster.

The body gets its calories from food. If you eat too much, you provide your body with more calories than it needs. It stores the extra calories as fat.

The process also works in reverse. If you don’t consume enough calories, your body starts burning its fat. This allows it to retrieve the calories stored within.

Using a quality fat burning diet pill can be a very good way to lose weight, but they should are not a magic pill.

Fat burners

Like any other type of diet pill, fat burners have to be used alongside a calorie-controlled diet. If you continue to overeat, using a fat burner won’t cause you to lose weight.

To get the best results from a fat burner you need to be already losing weight. Eating less food than your body needs will cause this to happen.

Exercise can further speed up your weight loss by causing you to burn extra calories per day. When you bring a fat burner into the equation it acts a bit like a turbo-charger on a car and makes things faster.

This point has already been made, but it’s important enough to be worth repeating. To get the best results from a fat burner you need to be already losing weight.

Thermogenic Fat Burners

All fat burners speed up the metabolism. Thermogenic fat burners cause the body to lose further calories as heat.

Thermogenic fat burners are very popular. They are also very powerful because they help you to burn extra calories in two different ways.

Thermogenesis is an ongoing process that’s happening 24 hours a day. That’s why human flesh is warm.

Thermogenic fat burners increase thermogenesis by triggering a slight elevation in body temperature.

The rise in body temperature is barely noticeable unless you are exercising. Yet, it’s enough to cause the body to lose a lot of extra calories throughout the day.

Many natural ingredients have thermogenic fat burning capabilities. The capsicum extract taken from red hot chilli peppers is a good example. It’s one of the best natural thermogenic fat burners available.

Capsicum thermogenic

Capsicum contains a compound called capsaicin. This the compound that speeds up the metabolism and raising the body temperature.

Red hot chilli peppers are not the only pepper that provides capsaicin. It can be found in many other plants belonging to the genus Capsicum.

Research shows less fiery forms of red pepper can increase diet-induced thermogenesis. However, red hot chilli peppers are one of the most potent forms.

Unfortunately, capsicum extract can be hard on the stomach. Especially when taken in concentrated form.

Researchers at OmniActive Health Technologies have developed a superior form of capsicum extract. It’s called Capsimax and it’s very gentle on the stomach. It’s called.

Capsimax uses a special “OmniBead” technology that delays the release of capsicum. This allows people to get all the benefits without unpleasant gastric burning. It’s a key ingredient in PhenQ. This is likely to be one of the reasons behind the product’s phenomenal success.

Green tea is also a respected thermogenic fat burners and research shows it works for up to 24 hours. It’s also rich in antioxidants that are good for the heart and help protect the body from disease.

Green coffee bean extract is another good fat burner that’s rich in antioxidants. The chlorogenic acid it provides helps prevent fluctuations in blood sugar and insulin. In so doing it can prevent sudden cravings for sweet food.

Appetite Suppressants

Appetite suppressants are also a popular type of diet pill. That’s not surprising. Hunger is an unpleasant sensation and appetite suppressant help take it away. In 2024 there many good brands of appetite suppressing pills available over the counter and online that have an excellent track record.

When you are eating less food, if you can’t control your hunger it may control you. Giving in to hunger is one of the main reasons so many diets fail.

There are many ways to take away hunger. The prescription drug Phentermine does so by causing stress reaction called flight or flight.

Appetite suppressants

Triggering fight or flight is not a safe way to lower the appetite. Researchers have established chronic activation of this survival mechanism impairs the health.

Some supplements contain ingredients that increase levels of the “feel-good” hormone serotonin. Among other things, serotonin is the hormone that regulates the appetite and the mood.

Other natural ingredients are alleged to suppress hunger by stifling the production of the hunger hormone, ghrelin. This claim is often made for nopal. However, it could be argued the powerful appetite suppressing ability of the cactus extract is actually due to the fact that it’s so high in fibre.

Glucomannan – Arguably the Best Appetite Suppressant

Many high fibre ingredients can help suppress hunger by making the stomach feel full. Psyllium husk is a good example, but glucomannan is probably the best stomach filler of all.

When the stomach is empty, ghrelin levels increase. The brain senses the increase and responds by emitting feelings of hunger. When the stomach is full ghrelin levels drop and the hunger goes away.

Glucomannan is a water-soluble fibre. It comes from the roots of the konjac plant. Glucomannan is incredibly absorbent. It  absorbs up to 50 times its own weight in water.

glucomannan for weight loss

There are other ingredients that can absorb water, but none of them is capable of soaking up such a great volume.

When combined with water, glucomannan expands and forms a gelatinous mass. It’s the presence of this mass in the stomach that provides the appetite suppressing effect.

The appetite suppressing capability of glucomannan has been the focus of numerous clinical trials. It’s ability is proven and it also lowers cholesterol.

Research shows women find it especially difficult to control hunger urges. This means they require extra help. Glucomannan is one of the key appetite suppressing ingredients used in the Leanbean. That’s a good endorsement for its potency. The product is renowned for it ability to reduce hunger.

Fat Blockers and Fat Binders

Fat blockers and fat binders assist weight loss by reducing the number of calories the body receives each day. Although many people use the terms “fat blocker” and “fat binder” interchangeably, they are not always the same.

Fat blockers are a type of diet pill that blocks the absorption of dietary fat. Fat binders are a type of fat blocker that works in a specific way. So, although all fat binders are fat blockers, not all fat blockers are fat binders.

Fat is a high-calorie nutrient. Each gram provides nine calories. A gram of protein or carbohydrate provides just four.

A low-fat diet plan is not a no-fat diet plan. Most food choices contain a little fat. However, fat blockers prevent around 30% of all fat consumed from being absorbed.

Obviously, all that undigested fat that is not absorbed has to go somewhere. It doesn’t just vanish, it passes through the body and is passed as waste matter in the normal way.

Fat Bllocking

It should come as no surprise to learn the presence of blocked fat in the faeces makes it softer and oilier than normal. This is visible evidence the fat blocker is doing its job.

Fat binders are the most common type of fat blocker. The prescription weight loss medication Orlistat is a notable exception.

The drug weakens a digestive enzyme called lipase. This enzyme is responsible for breaking down dietary fat. In its weakened state it becomes less efficient. This what provides the fat blocking effect.

Lipase is only responsible for breaking down dietary fat. The body uses different enzymes to process protein and carbohydrate so they are digested in the normal way. Although Orlistat has value as a weight loss aid, it can also cause side effects. The natural ingredients used in dietary supplements are gentler on the body and the results provided are just as good.

Chitosan – The Good, the Bad and the Ugly

Chitosan is a natural fat blocking ingredient, but there are two forms and the most popular one is not suitable for all.

The most commonly-used form of chitosan comes from the shells of lobsters, crabs and shrimp. The exoskeletons of some other sea-living crustaceans contain it too.

This type of chitosan is not suitable for vegetarians. It can also present health hazards to anyone who has seafood allergies.

The second type of chitosan comes from certain species of fungus. It well tolerated by most individuals, but many diet pill manufacturers fail to state which version is in use.


Regardless of its origin, chitosan is an ingredient that works in an interesting way.

The human digestive enzymes are incapable of processing chitosan. They have no effect on it at all so it passes through the body untouched.

When chitosan encounters dietary fat in the stomach it “binds” with the fat molecules.

Once bound, the fat molecules are impervious to the human digestive enzymes too.

Nopal (Opuntia ficus-indica) is a research-backed fat binder and there is clinical evidence that proves it works. As established earlier in this article, nopal is an appetite suppressant as well.

It also provides amino acids that boost energy levels and prevent diet-related fatigue. On top of this, nopal can help regulate blood sugar levels. It does a lot of things that chitosan cannot.

Carb Blockers

Carb blockers work in a similar way to fat blockers. The big difference is they weaken the digestive enzyme alpha-amylase. It’s the enzyme that breaks down carbohydrate in the stomach.

A number of natural ingredients posses carb blocking abilities. Apple cider vinegar and garcinia cambogia are two good examples.

However, despite the virtues of the other options available, most dedicated carb blocking products contain just one active ingredient—white kidney bean extract (phaseolus vulgaris).

In expert circles, the use of carb blockers continues to be a controversial subject. The American Food and Drug Administration (FDA) state there is insufficient evidence to prove carb blockers work.

A lot of experts share the FDA’s opinion

Despite the pessimism, there is still evidence to suggest white kidney bean extract is a carb blocker that works.

A study published in the International Journal of Medical Sciences in 2007 is particularly interesting.

The study involved 60 overweight individuals who had maintained a stable weight for six months or longer.

The members of both groups had to follow high-carb diets. The study period was 30 days. The members of one group received 445mg doses of white kidney bean extract before their meals. The members of the other group received a placebo.

At the end of the study, the data showed the group taking white kidney bean extract had lost the most weight. The group members also achieved more respectable decreases in waist circumference.

The results of another study provide further evidence that white kidney bean works.

White Kidney Bean

Researchers from the University of California enlisted the help of 25 healthy volunteers. As with the other study, some of the volunteers received a placebo. The rest received a proprietary blend of white kidney bean extract.

The study lasted four weeks. All the participants followed a structured weight loss program that included diet and exercise. They received two doses of their allotted pills every day.

However, the doses of white kidney bean extract were considerably higher than those used in the other study. Each dose provided 1000mg.

All the participants successfully lost weight. The placebo group members lost 4.7lbs. The active group members did much better with a weight loss of 6lbs.

Despite the fact that some experts claim otherwise, fat blockers do appear to have value. Especially white kidney bean extract. A number of other studies show that it works.

Although carb blocker side effects are neither common or severe, they do sometimes occur.

The presence of undigested in carbohydrate in the intestines may cause some people to experience discomfort. It can also cause a build-up of intestinal gas. Diarrhoea and bloating are two further possible carb blocker side effects.

The side effects a minority of people experience are due to the undigested carbs fermenting in the intestines. The good news is, carb blocker side effects usually go away with time.

In Summary

Hopefully, the information provided in this article has given you a helpful introduction to the four main diet pill features. This will help you understand how diet pills really work.

Some diet pills provide just one of the main diet pill benefits others provide two or more. The best ones tend to be those that offer several because they help cover all the bases and give a greater level of support.

Diet pills that offer a combination of fat burning and appetite suppression are very popular. Diet pills that focus on just one of these areas are available, but dedicated fat blockers and carb blockers are more common.

Blocker type supplements are also the most open to abuse. Many people buy them with the intention of using them as cheat pills instead of weight management aids.

People who want to continue eating high-fat foods without gaining weight. often buy fat blockers. People who love pizzas, pasta, and other high-carb food are more likely to go for carb blocking products.

When it comes to weight loss, cheaters never win. Using fat and carb blockers in this manner also increases the likelihood of side effects.

Using fat blockers as a cheat pill can have particularly devastating consequences.

Fat blockers block around 30% of all ingested fat. This is always the case. Consuming extra fat gives them more fat to block. This can result in embarrassing attacks of explosive diarrhoea.

Whatever type of diet pill you choose to buy, it’s important to make the necessary dietary changes. Getting some extra exercise is also a good idea. You can’t rely on a pill to do all the work.

Are still unsure which is the best type of diet pill to buy? The best thing to do is buy one that offers support in many different areas.
