While things like weight-loss apps help us collect data and track progress and meal delivery services ensure that consistency is convenient, appetite suppressants help preserve our resolve. Findings from the American Psychological Society explain that willpower, the ability to maintain self-control in areas such as eating and exercise, erodes over time.(1) It's accelerated when the number of barriers and discomfort of what we are doing grows. This explanation sheds light on why so many people are unable to stick with their weight-loss goals.

Appetite suppressants play an integral role in helping remove common barriers to weight loss. When paired with healthy eating and fitness choices, appetite suppressants may help increase our odds of success.

How Appetite Suppressants Work

Appetite suppressants affect the hypothalamus, a portion of your brain responsible for regulating appetite. Suppressants work through a combination of active ingredients that alter the signals sent to this part of your brain to mimic the feeling of satiety.

You need to be in a caloric deficit when you're losing weight. Feelings of hunger will and should appear as a result. While it is a sign that your body is working correctly, continual feelings of hunger and increased cravings will deplete your willpower quickly. That's where an appetite suppressant comes in.

An appetite suppressant can be a powerful tool, especially when it's used to complement a healthy caloric deficit and some form of physical activity.

What to Look for in Appetite Suppressants


Active Ingredients

It's important to pay attention to the active ingredients of any product you are considering. Countless formulations utilize different pathways to reduce your appetite. It's best to check the active ingredients to make sure there isn't something you'd react negatively to.

Unfortunately, appetite suppressants can be most prone to marketing hype. Be wary of products that contain more than a few ingredients. This may indicate that the dosages are too small to be effective. Look out for labels that promote proprietary blends without divulging what they are made of.

The appetite suppressants we've included on this list have been vetted to ensure that the active ingredients contain an effective dose, the amount you need to reap its benefits. We've only included appetite suppressants that reveal what is contained in their proprietary blends.

Vetting Claimed Benefits

Research claims thoroughly when deciding on an appetite suppressant. While most manufacturers don't intend to deceive their customers, checking their claims is important. It doesn't need to be complicated but can go a long way in making sure your money is well spent.

A few things to keep in mind as you research appetite products:

  • Pay attention to the active ingredients and do an online search
  • Check to see if there is clinical data to back up their claims
  • Ensure that the product contains the required dosage to be effective

Benefits of Appetite Suppressants

If you're trying to lose weight, appetite suppressants can be a useful tool to help you curb your cravings and resist everyday food temptations. If you're trying to eliminate certain foods from your diet—like sweets—an appetite suppressant can help you manage your snacking habits by keeping you fuller for longer. This doesn't necessarily mean that they're a quick fix. Proper diet and exercise should always be the first step, as they can help get you to where you want to be health-wise, but appetite suppressants can help boost you along the way.

Possible Side Effects of Appetite Suppressants

Side effects can vary from person to person based on the formula used in the supplement and whether or not you're taking the recommended dosage. If you are sensitive to caffeine, you're more likely to have side effects when taking an appetite suppressant that contains stimulants. Common side effects of appetite suppressants include:

  • Constipation
  • An increase in heart rate or blood pressure
  • Dizziness
  • Dry Mouth
  • Trouble sleeping
  • Headaches
  • Stomach issues such as nausea or vomiting

If you're interested in taking a fat burner but are concerned about potential side effects, consult your doctor before adding them to your nutritional routine.

How Much Do Appetite Suppressant Pills Cost?

The price point for appetite suppressants can vary depending on the ingredient list, but as a rule of thumb, you can expect to pay between $1 and $2 per serving. Once you find an appetite suppressant that you like, you can typically save money by stockpiling larger quantities. For example, buying a two-pack or a larger bundle will often generate some significant savings.

Our Final Takeaway

To get the fit, trim figure you dream of, it’s crucial to exercise regularly and to practice sound nutrition. A big part of that is controlling cravings, and reducing the size of the portions you eat. That’s where a good appetite suppressant can be invaluable. As you seek the best appetite suppressant, we hope our recommendations provide a useful starting point.

FAQs About Appetite Suppressants


What suppresses your appetite the most?

Adjustments to meal timing, frequency, and macronutrient composition will go a long way to preventing blood sugar levels from spiking. It also increases insulin sensitivity and gives your body time to signal to the hypothalamus portion of your brain that you are full.

A strong nutritional foundation will enhance anything else you utilize. Hunger pain and intensified appetite are major challenges when it comes to maintaining a caloric deficit. This is where appetite suppressants will be highly effective and help you maintain consistency.

If you are looking for a short-term solution with powerful ingredients, using appetite suppressants like PhenQ may be a great option. Although it contains caffeine as a stimulant, it's used sparingly to reap its benefits while minimizing the risk of adrenal fatigue.

Have a lot of weight to lose? You'll want to select a product that is approved for long-term use. This means you'll need to omit stimulant-centered formulations in favor of natural ones that use alternative methods to suppress your appetite.

Regardless of your route, the most effective appetite suppressant will be a combination of lifestyle changes and supplementation that matches your specific goals.

What is the difference between over-the-counter and prescription appetite suppressants?

Over-the-counter (OTC) appetite suppressants can be purchased both online and in stores. There are a host of non-prescription solutions you can leverage in order to help control your appetite. The most effective method will vary based on a number of individual factors, including your age, gender, and how much weight you have to lose. You should always consult with your doctor when taking a new supplement, but purchasing over-the-counter doesn't require a doctor's permission. It's up to you to discontinue use if you do run into any of the possible side effects of appetite suppressant supplements.

Your doctor may prescribe you an appetite suppressant so that they can monitor the side effects and results. If you have an underlying health issue, such as high blood pressure or Type 2 diabetes, an appetite suppressant that can be used safely under your doctor's supervision is your best bet.

What are the best appetite suppressant ingredients?

Ingredients that are backed by research and shown to help aid in weight loss and appetite suppression are what you'll want to look for when selecting an appetite suppressant. If you're ever in doubt about a certain ingredient, it doesn't hurt to look it up. Here are a few of the more common ingredients used in appetite suppressants:

  • Caffeine
  • Capsicum
  • Garcinia Cambogia
  • Green Tea Extract
  • L-carnitine
  • Chromium
  • Choline
  • Glucomannan
  • L-theanine
  • Vitamin B Complex

Keep in mind, not every product you look at is going to feature all of these ingredients. That doesn't necessarily mean that it won't be as effective.

Are appetite suppressants safe to take?

In general, appetite suppressants are safe to take as long as they are consumed in an intended way. It's not just about diminishing returns. Overdosing can pose a risk to your health. This is important, especially for suppressants that utilize stimulants like caffeine, guarana, or ephedra. The combination can result in severe consequences if you supplement with stimulants from other sources like coffee or energy drinks.

If you want to lean on the side of caution while still reaping the benefits of an appetite suppressant, consider choosing one that is stimulant free and based on natural ingredients. These are often more forgiving and just as effective.

Who should use appetite suppressants?

Appetite suppressants are especially helpful for those looking to lose weight or reach a specific body composition goal. For those new to losing weight and exercise, getting an appetite suppressant that also helps address some of the barriers associated with starting out with weight loss would be a great option.

Appetite suppressants aren't just for weight loss. A growing number of individuals are adding these products into their daily rotation to help with weight management, healthy food choices, and an overall sense of well-being.
