We are, in essence, what we eat. Unfortunately, most of the foods we consume daily do not aid in weight loss. People who want to start a weight loss journey on a high-carbohydrate, high-sugar diet are basically setting themselves up for failure.
No matter how much working out in the gym or following a diet helps, you’re in trouble if your appetite remains high.
You will consume more food and lose less body fat if your appetite is not suppressed. Even so, as you go to the gym, you’ll need to eat more to make up for the energy you’ve lost. And this isn’t the way to slim down.
Some people actually remain disciplined with diets and working out routines and get to lose weight. But studies[1] show that they regain all that back in just one year. This is because the body triggers the production of weight-regulating hormones[2]. These hormones directly affect your appetite, body fat distribution, and metabolism rate. And this is where an effective appetite suppressant comes in to help.
This article reveals some of the most effective appetite suppressant supplements for burning fat and kick-starting your weight loss journey.

Who Should Use Appetite Suppressants?
Obese people with a Body Mass Index (BMI) over 30 can benefit from the best appetite control that promotes weight loss. People with diabetes and those with high blood pressure and a BMI of 27 or higher should use appetite suppressant supplements along with fat burners. These three groups of people are the most affected by diet, and they require dietary supplements to help them control hunger. These individuals must primarily control their blood sugar levels by curbing food cravings.
Another group of people who may use appetite suppressants is those trying to lose weight and want to keep track of their eating habits to keep the weight down.
Nonetheless, this means that both men and women in these groups may benefit from appetite suppressing supplements. Women have specific appetite suppressants, such as the best female fat burner.
How Do Appetite Suppressants Work?
Anorectics, another name for appetite suppressants, work intelligently[3] to trick your brain into thinking you are full.
They work in one of the following three ways:
- One version of the weight loss supplements contains dietary fiber. These suppress your appetite by filling your stomach when you take them. And the result is you feel full; thus, you do not get cravings or feel like eating.
- The second-way many natural appetite suppressant supplements work is by targeting the adrenal gland. There is a block between message transmission from the gland to the brain to signal hunger when this happens. In turn, your food intake is restricted to only the set meal times.
- Thirdly, some appetite suppressants work by increasing serotonin levels in the body. This feel-good hormone then tricks the body into thinking that it is full and it does not need to consume any food at that particular time.
7 Best Appetite Suppressant Pills to Control Hunger in 2023
PhenQ
Up To 50% Off When Buying In Bulk
PhenQ appetite suppressant food supplement is a five-in-one formula that is thermogenic, organic, and herbal. So much so, it is one of the best herbal appetite suppressants in the market with numerous benefits we look at next.
- It’s a five-in-one recipe
- It’s simple to place an order directly online
- Pharmaceuticals and synthetics are not used.
- May help you lose weight
- Only a few countries have access to it.
- When compared to other brands, it is a little pricey.
The list of ingredients that make this fantastic blend are:
Capsimax powder
This PhenQ appetite suppressant supplement component is a potent fat percentage reducer[4]. It is also a great ingredient that modulates your metabolic rate[5] and food intake.
Chromium picolinate
Chromium picolinate also aids in appetite suppression by delivering essential sugar to your cells. This component is particularly effective[6] at reducing sugar and starch cravings.
Caffeine
Caffeine is a stimulant that helps you concentrate and rejuvenates the body. This is beneficial when using the supplement in conjunction with a fitness routine. Caffeine’s stimulating impacts[7] also aid in appetite suppression. You will experience fewer hunger pangs.
Nopal
The inclusion of Nopal extract[8] increases the supplement’s fiber content. Fiber is reported to help in the reduction of hunger and the suppression of an individual’s appetite. It can also help you lose the weight gained due to fluid retention more quickly.
L-Carnitine fumarate
L-carnitine is known primarily as a fat burner, body weight, and fat mass reducer[9], but there is conflicting evidence. It is unlikely that it will result in significant weight loss. On the other hand, studies back up its use for well-being, cognitive function, and preventative medicine.
Weight loss pills with this component may also help those who need to lower sugar levels, such as those with diabetes or pre-diabetes.
Leanbean

Leanbean pills form a gel-like viscous substance once it gets to the stomach, thanks to the ingredient glucomannan. This fullness helps you keep your calorie intake in check. And the effect seen is a reduction in your waist circumference due to the loss of belly fat.
This appetite suppressant also purports to significantly boost your metabolism thanks to thermogenesis[19] triggered mainly by Choline. Besides that, they promise to offer you energy-filled workouts, countering any fatigue.
As the brand puts it, this blend of natural ingredients has been designed to help females mostly. They have studied female cravings and formulated the appetite suppressant based on them.
Here is a list of the natural ingredients they use:
Glucomannan
Glucomannan[20] is a fermentable, water-soluble dietary fiber derived from the elephant yam tuber or root known as konjac. It goes to the stomach, absorbing moisture and transforming into a viscous gel when eaten. This gel fills your stomach, making you feel fuller and reducing your desire to eat, making it an effective appetite suppressant in the formula.
Choline
This ingredient is usually produced by the liver naturally, which aids in thermogenesis. Supplementation aids in a boost in lipid metabolism and homocysteine metabolism[21].
Homocysteine (Hcy) is a sulfur-containing amino acid that is formed when methionine (Met) is converted to cysteine (Cys). Hyperhomocysteinemia (HHcy), or high levels of Hcy in the blood, is widely implicated in the development of cardiac, cerebral, and peripheral atherosclerosis. Atherosclerosis is characterized by a plaque buildup in the blood vessels that impede the flow of blood and put more work on the heart.
B vitamins
The B vitamins available in this appetite suppressant are B6 and B12. This duo helps to boost metabolism and fight fatigue.
Chromium picolinate
This ingredient aids in the regulation of blood glucose[22] content.
Chloride
Chloride combines with other elements like potassium to help the stomach produce vital acids to promote a healthy digestive system. It acts as an electrolyte since it is electronically charged. A healthy digestive system does not store the excess fats or proteins that could otherwise mean weight gain.
Zinc
The zinc in this appetite suppressant is instrumental in helping curb any pain and inflammation resulting from working out. It promotes lipid and carbohydrate metabolism and converts proteins to lean muscles.
Taking Zinc combined with a low-calorie eating plan has been shown to reduce anthropometric metrics, inflammatory cytokines, glucose intolerance, and appetite in obese people, suggesting that it could be beneficial in managing obesity. This means it improves bodyweight management[23].
Turmeric
Turmeric’s most instrumental component is curcumin[24] which is also helpful in offsetting any inflammatory responses. Besides that, it is also another potent thermogenic spice aiding in fat burning in the body.
Piperine
This substance is what gives black pepper its unique aroma. This ingredient is also thermogenic, and it helps the body absorb other nutrients better. Piperine[25] helps in digestion and metabolic efficiency, resulting in less fat accumulation in our bodies.
Garcinia Cambogia
This organic ingredient contains hydroxycitric acid[26]. HCA, or hydroxycitric acid, appears to inhibit citrate lyase, an enzyme that your body needs to make fat. It also increases serotonin levels in the brain, which may cause you to feel less ravenous.
Green Coffee
Green coffee contains chlorogenic acid, a great antioxidant reducing any oxidative stress in the body.
Acai Berry
The Acai berry[27] is also an antioxidant plus a fat profile modulator. Its effectiveness as a weight loss-promoting ingredient further scientific study.
PhenGold
As the best over-the-counter appetite suppressant product, PhenGold formula contains a long list of vitamins, herbs, and amino acids with each one having commendable benefits.

The formula is all-natural, and here is a complete list of what is included in the recipe to suppress appetite and facilitate weight loss:
Green tea

Rhodiola rosea
This substance helps with appetite suppression, natural fat burning, and fighting off fatigue[47]. This energy-boosting nature helps one stay motivated to stick to a healthy diet, thus curbing cravings while burning that excess fat. It enables you to remain in line with your weight loss journey.

B Vitamins
PhenGold appetite suppressant contains Vitamins B3, B6, and B12. These three B vitamins[49] help keep your metabolic rate at an optimized rate. B3 is essentially helpful in curbing inflammation which is fundamental in speeding up the healing process after workouts.
B6 is a potent protein, carbohydrate, and fat metabolizer. It helps in sustaining a healthy weight loss process. And lastly, B12 aids in boosting energy[50] within your cells to combat tiredness.
Green coffee
Green coffee is a herbal appetite suppressant that decreases the number of fat reserves. It contains a substance called chlorogenic acid[51] that significantly reduces the amount of glucose and fat in the body. It is ideal as it helps prevent weight gain since the body is not storing any excess fat.
Cayenne pepper
This is an effective calorie burner since it naturally triggers a process called thermogenesis[52] in the body. The body naturally produces heat which then burns all that excess fat naturally.
L-tyrosine
L-tyrosine may help in boosting energy levels and concentration in the body. The mechanism it uses is working in the brain in improving cognitive functions[53]. So much so that you stay focused and motivated throughout your weight loss journey.

Green coffee bean extract
This ingredient[10] can reduce calorie absorption by one to two hundred calories.
Cayenne powder
Cayenne pepper has been associated with increased fatty acid oxidation and thermogenesis, and studies suggest it can help you feel full[11] when you consume it.
Glucomannan
According to a study[12] published in the International Journal of Obesity, obese people who took two doses of 500 milligrams of Glucomannan per day lost more weight than a control group despite making no other dietary changes. Instant Knockout contains nearly two grams of it, so from this finding, it will help you feel full.
Caffeine anhydrous
Increased fat metabolism and thermogenesis have been linked to caffeine. It may increase adrenaline[13] from the adrenal gland which aids in fat breakdown.
Green tea leaf extract
Green tea has elements that are powerful antioxidants helping the body to fight off oxidative stress. It especially helps you lose weight around your belly[14].

Here are some of the commendable ingredients in this natural appetite suppressant:
Green tea extracts
Green tea extract has been shown in numerous studies to help with weight loss[54], blood sugar regulation[55], preventing disease[56], and workout regeneration[57]. It can also aid in maintaining healthy skin[58] and the reduction of blood fat percentage[59], blood pressure regulation[60], and cognitive performance[61].
L-tyrosine
This amino acid works as a natural appetite suppressant. It aids in producing thyroid hormone[62], which modulates the metabolic activity and fat burning. It is critical to converting calories into energy. Unburned calories constitute the fat in your body.
It is also a potent element that reduces neurotransmitters’ depletion rate, optimizing your memory[63] and concentration.
L-theanine
This substance gives this a flavorful taste and texture recognized as umami. Umami flavors have been shown to reduce appetite, which can help with weight loss. So much so, it aids in weight loss[64] and enables you to avoid any weight gain.

Here are the ingredients that facilitate this:
Grains of Paradise
The plant Grains of Paradise[28] is closely linked to ginger. The seeds are used as a seasoning as well as for medicinal purposes. Substances present in grains of paradise seeds appear to reduce swelling, destroy bacteria, and aid in burning body fat.
Green Tea
Green tea is loaded with antioxidants, caffeine, and one special flavonoid called catechin. These compounds have been shown to speed up the metabolism in several studies[29].
Catechins can aid in the breakdown of excess fat, and both catechin and caffeine can cause the body to use more energy. Another review[30] done in 2010 attest that the elements found in green tea also help one keep their weight in check. It was a small but positive effect.
Caffeine
Caffeine is one of the widely known stimulants. Thus, it helps boost energy levels when it comes to appetite suppressants.
Caffeine has also been shown to reduce appetite, defer emptying of the stomach, and impact appetite hormones, which can aid in weight loss. Caffeine has also been shown to aid weight loss by increasing fat and calorie burn[31].
Glucomannan
The soluble dietary fiber glucomannan appears to be the most effective weight loss agent. It suppresses the appetite[32] as well as the amount of food consumed. Glucomannan can also absorb water[33] and form a thick gel, thus decreasing the appetite and lowering blood sugar. Those on diabetic medications should monitor their blood sugar to assure it does not go too low.
Glucomannan bulking property aids in boosting feelings of fullness and delaying stomach emptying; as a result, it can help you eat less[34] and lose weight.

Powher Cut
Ultimate Life is the company behind this big brand specializing in this product as the best appetite suppressant for women. They are also the company behind Leanbean that we looked at above.
- A straightforward formula that lists all of the ingredients used
- Aids loss of weight when used in conjunction with a low-calorie diet
- Allows the body to perform essential processes
- A bit expensive
- You have to take six capsules each day
- The formula lacks B vitamins which are vital in weight loss
Powher appetite suppressant pills are exclusively sold via the main brand’s website. They offer their clients free shipping when you buy two plus items via the website. They also offer a 90-day money-back guarantee.
The brand prides itself on producing its formula in FDA-registered facilities that only use healthy and sustainable practices to make this appetite suppressant supplement.
All in all, here are the ingredients found in the Powher appetite suppressant for women:
Glucomannan
The primary ingredient in the Powher appetite suppressant is Glucomannan[36]. It’s also identified as Konjac Root Extract, and it’s a dietary fiber derived from the Konjac plant’s root.
Glucomannan helps you lose weight in the context of an energy-restricted diet. It is effective once it is included in a formula with at least 3g per day, divided into three independent 1g dosages, as it is in this appetite suppressant.
Choline
Choline[37] comes in a 90 mg daily dose in the Powher Cut formula. Choline is an important nutrient that adds to normal fat metabolism. This lipid metabolism is vital in the production of energy from the breakdown of fats to energy.
Caffeine
Caffeine is a stimulant. And the one used in this Powher Cut appetite suppressant is the coffee arabica extract that consists of 100 mg per daily serving. Each capsule of this effective appetite suppressant contains around 16.6 mg of caffeine.
To put that quantity in perspective, a typical cup of coffee contains about 100 milligrams of caffeine. This is a potent booster in your energy levels, keeping you grounded and motivated in your journey to lose weight.
Magnesium
Another active ingredient we need to get from our daily healthy diet is magnesium, an essential mineral that plays a critical role in a handful of biological functions.
Magnesium boosts standard energy release, decreases stress and exhaustion. This enhanced your working-out performance[38] tenfold. When it comes to appetite control, magnesium acts as a power supply converting food into energy[39] and coordinating cell respiration with the help of ATP. This process may assist you in burning more calories during endurance workouts, resulting in fat loss.
Selenium
This is yet another essential mineral that we must obtain through our healthy diet. Your body uses this nutrient to keep your thyroid functioning properly[40]. The thyroid gland regulates the hormones in your body.
Selenium also tends to help safeguard your body from oxidative stress by playing an important role in metabolism. Furthermore, selenium may aid in enhancing your immune system[41], preventing age-related mental decline[42], and even reducing your risk of cardiovascular disease[43].
Chromium Picolinate
Chromium is a trace element that we must obtain through our dietary habits. It aids in the normal metabolic processes of macronutrients and the maintenance of healthy blood sugar levels. In one 8-week research[44] study, chromium picolinate at 1,000 mg/day reduced food intake, appetite, and hunger pangs in healthy overweight women.
It is the best appetite suppressant for women who want to control their appetite to stay slim and fit.

How To Choose Appetite Suppressant Pills Over The Counter
Deciding on an appetite suppressant is a big decision that first and foremost needs medical advice. This means that before you decide to go with the best appetite suppressant over the counter, ensure that a doctor has assessed your health and given you the go-ahead.
More pointers that can help you select the best appetite suppressant pills over the counter are:
The Brand’s Reputation
The first thing you need to look at is what people are saying about the brand. When it comes to selecting diet pills, the company’s reputation is critical. It shows their reliability, transparency, and effectiveness.
And the best way to get all this information on an appetite suppressant brand is through the internet by reading such a product review, social media, and reviews left behind by past clients.
The Diet Pills Testing
This mainly refers to in-house and third-party testing of the appetite suppressant’s purity and quality. When a brand is open about these two kinds of testing, they are willing to take accountability for their product.
The testing will also confirm the quantities of the ingredients in the product and assure that no contamination has taken place.
The Type of Ingredients
Suppose the appetite supplement is fully organic or has synthetic fillers. Ideally, it would help if you went for the best appetite suppressants that are organic since they have minimal side effects. Even so, when you look through the list of ingredients, stay clear from any appetite suppressant products that contain any substance you are allergic to.
This also applies to the facilities they are made of; some are packaged in locations that also create other significant allergens like nuts and dairy, so read the label carefully.
Other things you can consider are your dieting habits like vegan or vegetarian. Your current health state is also a pointer you can use. For instance, if you have diabetes, ask your doctor for the best use.
Your lifestyle is also another factor. Some weight loss diet pills may work alone, while others require you to have a fitness routine for them to work. So take note of this as well before purchasing the best appetite suppressant over the counter. Lastly, ensure that the source of the suppressant is legitimate.
Precautions
One of the most important considerations when looking for the best appetite suppressant pills is your overall health. This means that one of the most important precautions is to seek medical advice, particularly if you are taking any other medications. When it comes to drug interactions, be cautious in this case.
The second point to remember is always to follow the dosage instructions on the package. Half the dose may not provide the desired results, and taking too much may result in side effects such as stomach upsets or digestive tract discomforts.
Finally, do not take appetite suppressant diet pills if you are unsure about their source. Many con artists sell millions of counterfeit appetite suppressant pills that may harm your health. To avoid this, buy the supplement from the company’s official website or a verified seller.
Final Thought
When it comes to finding the best appetite suppressant supplements, you now have seven options to consider. Each of the brands we’ve discussed has numerous advantages, including appetite suppression, weight loss, fat burning, boosted metabolism, improved brain health, and overall well-being.
Even though they are excellent appetite suppressants, you should conduct some preliminary research to ensure that they are the best for you. And a visit to your doctor for an evaluation should be the first stop. Nonetheless, stick to the dosage and make sure you get the genuine product to avoid any adverse side effects.
With that, we hope that one of these seven appetite suppressant products helps you achieve your ideal body and optimal health.
Frequently Asked Questions
Appetite suppressants are available in both prescription and over-the-counter (OTC) forms. Before taking over-the-counter diet pills, consult your doctor.
The B vitamins (especially B1, B2, B3, B5, and B6) can suppress appetite. B vitamins are found in foods, including milk, green/leafy vegetables, beans, legumes, and seeds.
Pills that boost metabolism and suppress appetite are dangerous because they can cause high blood pressure, a rapid heart rate, and lung and heart problems.
They affect the brain’s desire to eat. Diet pills can help you feel fuller faster with less food by controlling hunger pangs. As a result, you consume fewer calories and shed pounds.
