For you to lose weight, you have to maintain a caloric deficit. There’s simply no way around it. Without a caloric deficit, your body will not be able to help you shed weight. Even worse, limiting caloric intake can be easier said than done.
An appetite suppressant may help you limit your caloric intake and control your food cravings so you can finally achieve a caloric deficit.
All appetite suppressants claim that they can lower your appetite. Unfortunately, many don’t contain the right ingredients or dosages to back up their claims. Some products can reduce your craving for hours, whereas others make you feel full for only 30 minutes, only to make you crave food even worse.
To make your life easier, our research team has diligently looked into hundreds of appetite suppressants. We researched their ingredients & dosages, customer reviews, company reputation, and much more to separate the best appetite suppressants from the imposters.
Here are the very best products if you’re looking for an appetite suppressant for 2021 and beyond.

How We Ranked the Best Appetite Suppressants
All appetite suppressants claim they can block hunger and control food cravings. However, this is easier said than done. To rank the best appetite suppressants from the frauds, we used the following ranking factors:
Clinically Proven Ingredients & Dosages
Peer-reviewed studies have found several natural ingredients that can block hunger or control unhealthy food cravings. Some elements can effectively stop you from overeating, whereas other components do not. Fiber and herbal extracts that act similarly to fiber, for example, are known to trick you into thinking you are full. Capsaicin is another ingredient known to limit the caloric intake as well.
The more clinically proven ingredients added to a product, the higher we ranked it. We also preferred products that contained dosages that were clinically proven to be effective.
Appetite is subject to how an individual personally feels. Some people can feel hungry all the time, and others only feel mild hunger. To honestly rank the top appetite suppressants, we tested the top-ranked formulas on our list. Our editorial team rated each product and how it made them feel. It became clear that some appetite suppressants could reduce food cravings and hunger for a more extended period.
Transparent & Honest Advertising & Benefits
Any appetite suppressant that claims you can lose a large amount of weight with minimal effort or any exercise should be taken with skepticism. Some sketchy weight loss companies claim you can lose up to 20lbs. in just a few weeks, without dieting or exercising, for example. Other appetite suppressants claim they can prevent you from eating all day, which is unrealistic. We preferred companies that were transparent about what their products could do and avoided ridiculous marketing tactics.
Too many companies hide behind “proprietary blends” so they do not have to disclose all of the ingredients in their product. While we understand it is essential to prevent other companies from stealing formulas, we still prefer products that disclose their ingredients and dosages.
Some appetite suppressants focus entirely on curbing your hunger. Others deliver complementary benefits by acting as a thermogenic fat burner, carb blocker, or metabolism booster. We considered these complementary effects a bonus because you are more likely to see better weight loss results when combining appetite suppression with improved metabolic function.
The weight loss industry has always been riddled with scams, and today’s weight loss industry is no different. Some companies have created cheap, ineffective appetite suppressants to make a few dollars. Others have thoroughly researched and formulated their products to maximize effectiveness and safety. We preferred companies that had a stellar reputation for producing supplements that worked.
Cost & Overall Value
It is essential to find a quality appetite suppressant, regardless of what your budget is. Whether you’re willing to spend $20 or $200, you should be able to find a solid product. We featured appetite suppressants at various price points so that we could accommodate any budget. We also considered the price of each supplement based on its ingredients and dosages to maximize the value you receive from each product.
Hunger is very subjective and dependent on each individual. Some people may experience robust appetite suppression, whereas others may not. Several different factors can impact your appetite, which means a product may not quite work for you. This is why we preferred products that were backed by an explicit money-back guarantee and satisfaction guarantee. It shows that each manufacturer stands by their product by offering your money back – showing they are confident in their product.
The best way to figure out the best appetite suppressants was to read the actual customer reviews of each product. After all, what better way to get the average customer experience than to read what they had to say.
We examined whether or not customers enjoyed each product, whether or not they experienced any side effects if they lost weight, and if they would recommend the product to their friends and family. If the answers to our questions were primarily positive, we considered the product a better appetite suppressant and more likely to give you the desired results. However, we still avoided products that seemed overly fake or manufactured reviews because we found these products to be deceiving.
Who Can Benefit from an Appetite Suppressant?
Virtually anyone can benefit from an appetite suppressant. Some people take appetite suppressants once they’ve hit a weight loss plateau. Others take appetite suppressants to curb their unhealthy food cravings.
Some of the people who can benefit from taking appetite suppressants include:
- Anyone who is trying to lose weight
- Someone starting a new diet program – especially for the first time
- Someone who has hit a weight loss plateau and needs a boost to break through their plateau
- Anyone who struggles with unhealthy food cravings or lacks willpower
- Busy, on the go individuals who don’t have the time to eat full meals throughout the day
- Someone who needs to follow a low-calorie diet who wants to avoid hunger pangs
Side Effects of Appetite Suppressants
For the most part, appetite suppressants should not cause any severe side effects when used by otherwise healthy adults in proper dosages.
Per FDA regulations, appetite suppressants must use ingredients and dosages granted a GRAS status or generally recognized as safe. Although the FDA doesn’t regulate supplements, supplements must formulate their products from a list of ingredients that have been determined to be safe by otherwise healthy adults in standard dosages.
With that said, some ingredients found in appetite suppressants have been shown to cause side effects potentially. Some of these typical side effects include:
If you have a particular health condition or are taking any medication, then it is good to consult your doctor before trying an appetite suppressant. Although it is still unlikely, it is still entirely possible that these products can interfere with your medication.
If for some reason, you do feel like an appetite suppressant may not be suitable for you, then you should consult your doctor before trying the product. It likely won’t cause any side effects, but caution is always recommended.
Appetite Suppressant Dosage
It’s always important to check the label on your appetite suppressant to see their recommended dosage. Different ingredients commonly included in appetite suppressants all use different dosages, although not all dosages are known.
Most capsules require you to take two capsules 20 to 30 minutes before each meal. These ingredients should help you consume fewer calories when you eat, minimizing your caloric intake throughout the day.
However, science does give us a specific dosage of certain ingredients.
For example, glucomannan seems to work best when taken at doses of 2g to 4g per day. Garcinia cambogia looks effective at doses of 1g to 2g per day.
What Science Says About Appetite Suppressant
Several plants, herbs, vitamins, and minerals have been clinically studied and proven to help control appetite. Even better, most of these trials are double-blind, placebo-controlled studies, which are the gold standard for clinical trials. We’ll review the most conclusive data surrounding ingredients related to appetite suppression.
Many of the appetite suppressants on our rankings contain a trans-fat known as conjugated linoleic acid or CLA. CLA is primarily found in fatty animal products, and it is used in supplement form to reduce hunger, stimulate the breakdown of fat, and block appetite. Many appetite suppressants only contain CLA as its’ active ingredient because many experts believe it is.
Science suggests it does indeed have powerful hunger blocking and fat-burning effects. One study found that CLA increased fat burning and blocked fat production while increasing feelings of fullness in adult participants.
In a review of 18 individual studies involving CLA, researchers found that a 3.2g dose could reduce body fat. Another study found that taking 3.6g of CLA per day for 13 weeks led to lower overall appetite and greater fullness than a placebo. If you’re looking for a CLA supplement to lower your craving, then you should try one with at least 3g per serving.
You probably already take one of the best natural appetite suppressants daily. Coffee, the second most-consumed drink in the world, is a natural appetite suppressant. Studies have found that coffee can support weight loss by improving your metabolism and by increasing calorie burning. However, it can also help you eat less, reducing your daily caloric consumption.
One study found that taking caffeine 30 minutes to 4 hours before a meal could reduce the total number of calories consumed during that meal. Another study found that adults that drank coffee were less likely to eat after a meal and snack less throughout the day. This suggests that coffee can have appetite-suppressing effects all day.
Fiber supplements are amongst the most popular ingredients, and they are proven to work. Science is elementary too. Fiber works by soaking up water in your stomach, which creates a gel-like paste in your digestive tract. Your body cannot digest fiber, at least quickly, so it sits in your gut and makes you feel fuller for a more extended period. It also encourages healthy digestion of other nutrients and helps keep your bowel movements regular, promoting weight loss. This is why various forms of fiber are commonly added to weight loss supplements – particularly appetite suppressants.
Glucomannan is another popular ingredient found in most appetite-suppressing supplements. Glucomannan acts a lot like fiber because it absorbs water and turns into a paste. It promotes the feeling of fullness and delays stomach emptying, which makes you feel fuller for a more extended time.
A long-term study on glucomannan found that 3g of glucomannan taken once per day could significantly help obese adults drop body weight and fat compared to a placebo group. Another study involving 176 overweight adults found that glucomannan enabled adults to lose “significantly more weight” than the placebo group. Even though they were instructed to follow a low-calorie diet, they also had a noticeable reduced daily caloric intake than the placebo group.
Garcinia cambogia is relatively new in the appetite suppressant industry, but it has quickly become one of the most prized ingredients. Tens of thousands of adults take garcinia cambogia to suppress their appetite, block fat formation, and for weight loss. According to experts, garcinia cambogia fruit contains a compound known as hydroxycitric acid, or HCA, which possesses weight loss properties.
In one study, researchers found that garcinia cambogia reduced overall caloric intake, helping participants consume fewer calories per day – encouraging more significant weight loss. Another study linked garcinia cambogia to reduced appetite, lower body weight, and prevent new fat formation.
Gymnema Sylvestre is another herbal extract that isn’t known outside the supplement space. However, it’s a proven appetite suppressant. Gymnema contains a group of compounds called gymnemic acids. These acids prevent the absorption of sugar in your blood, which can stabilize your appetite.
Many of the studies involving Gymnema admittedly have involved animals, not humans. One study found that Gymnema helped animals maintain their weight while fed a high-fat diet for ten weeks. Other studies have found similar results.
Green tea extract is arguably one of the most popular ingredients added to weight loss in today’s supplements, and studies have found that green tea extract can help suppress your appetite. This is because green tea extract contains catechins and caffeine. Caffeine has proven appetite suppressing effects, as well as metabolism-boosting effects. Studies have found that the catechins in green tea, particularly EGCG, seem to suppress appetite to reduce overall caloric intake.
Finally, fenugreek is a popular appetite suppressing ingredient, and it has several benefits for the human body. Fenugreek is commonly added to appetite suppressants because its seeds are 45% fiber. Some of the fiber is soluble, and some are insoluble. These fibers have been linked to better appetite control, cholesterol levels, and blood sugar regulation, which is why fenugreek is a popular supplement.
It is thought that fenugreek works by slowing carb and fat absorption and delaying the emptying of your stomach. In one study, researchers gave obese adult women 8g or 4g of fenugreek fiber. The 8g group ate less and felt fuller than the 4g group, suggesting that fenugreek can help with appetite suppression.
Overall, appetite suppression can play a vital role in your ultimate goal of losing weight. An appetite suppressant encourages you to consume fewer calories daily, making it easier to lose weight by maintaining a caloric deficit. Science has told us that coffee, caffeine, green tea, fiber, and various herbal extracts can support healthy appetite suppression to help you reach your goals.
