Let’s get right into it!

What Are Appetite Suppressants?

Rising health issues are both a boon and bane: Problems like obesity, while dreaded, have also given rise to innovative ideas to help mitigate its consequences — appetite suppressants.

Introduced as handy little capsules or powders, appetite suppressants, also known as anorexiants, are compounds designed to reduce the desire for food by influencing the body's hunger and satiety signals. 

While some appetite suppressants are available over-the-counter, others require a prescription from a healthcare professional. This is because appetite suppressants can have potential side effects for people with underlying medical conditions, and are to be used with caution and proper guidance.

How Do Appetite Suppressants Work?

Appetite suppressants work by targeting various physiological pathways that regulate hunger and satiety signals in the body. 

To put it simply, the compounds contained in appetite suppressants can influence the levels of neurotransmitters, hormones, and other signaling molecules involved in the complex mechanisms that govern our appetite and food intake.

Affecting Neurotransmitter Levels

Certain appetite suppressants can increase the levels of neurotransmitters like norepinephrine and serotonin, which play crucial roles in regulating appetite and mood. When appetite suppressants influence these neurotransmitters, the result is reduced hunger sensations as well as increased feelings of fullness.

Influencing Hormones

Hormones such as leptin and ghrelin are key players in appetite regulation. Some appetite suppressants interact with these hormones, either by mimicking their effects or altering their production or signaling pathways, ultimately leading to reduced hunger and increased satiety.

Delaying Gastric Emptying

Certain appetite suppressants slow down the rate at which food leaves the stomach, prolonging the feeling of fullness and reducing the desire to eat more frequently.

Increasing Thermogenesis

One final subset of appetite suppressants are known to enhance the body's metabolic rate, leading to increased calorie burning, and potentially contributing to weight loss when combined with a calorie-controlled diet and exercise regimen.

It's important to note that the effectiveness and mechanisms of action can vary among different types of appetite suppressants — reactions and observable weight loss also depends on this method of action.

Different Types of Appetite Suppressants

Prescription medications: Typically prescribed by healthcare professionals, prescription-types are subject to strict regulations according to individual health requirements. Examples include phentermine, liraglutide, and bupropion/naltrexone combination drugs for weight loss.

Over-the-counter supplements: Many dietary supplements claim to have appetite-suppressing properties, often containing ingredients like caffeine, hoodia gordonii plant extract, or glucomannan fiber.

Herbal remedies: Certain herbs and plant extracts, such as green tea, garcinia cambogia, and bitter orange, have been traditionally used for their potential appetite-suppressing effects.

Fiber supplements: Soluble fibers like glucomannan and psyllium husk can promote feelings of fullness by absorbing water and expanding in the stomach, potentially leading to reduced calorie intake.

Appetite Suppressant Ingredients

While appetite suppressants are not entirely a magic solution for weight loss, some ingredients contained in them definitely help the weight loss journey along. 

Appetite suppressants often contain a variety of active ingredients, each with its own proposed mechanisms of action — including expanding by volume in the stomach, like a balloon.

Caffeine: A stimulant that can increase metabolism and suppress appetite by influencing neurotransmitter levels.

Hoodia gordonii: A succulent plant extract believed to mimic the effects of glucose in the body, potentially reducing hunger signals.

Glucomannan: A soluble fiber derived from the konjac root, which can promote feelings of fullness by absorbing water and expanding in the stomach.

Green tea: Rich in antioxidants and caffeine, green tea extracts are said to boost metabolism and aid in weight management.

Garcinia cambogia: This tropical fruit extract contains hydroxycitric acid (HCA), which is thought to inhibit an enzyme involved in fat production and potentially suppress appetite.

Conjugated linoleic acid (CLA): A type of fatty acid found in meat and dairy products, CLA is believed to have potential appetite-suppressing and fat-burning properties.

Bitter orange: Synephrine, also known as bitter orange extract, is a stimulant that may increase metabolism and suppress appetite.

Appetite Suppressants vs Weight Loss Supplements

While appetite suppressants and weight loss supplements share the common goal of supporting weight management, they differ in their mechanisms of action and intended purposes. 

Appetite suppressants primarily aim to reduce hunger and food cravings, making it easier to adhere to a calorie-restricted diet. They work by influencing the body's hunger and satiety signals, either through their effects on neurotransmitters, hormones, or other physiological pathways.

Weight loss supplements, on the other hand, encompass a broader range of products that work through various mechanisms to influence metabolic rates and fat formation (lipogenesis).

Increasing metabolism: Some supplements contain ingredients like caffeine or green tea extract, which are believed to boost metabolic rate and enhance calorie burning.

Blocking fat absorption: Certain supplements may interfere with the absorption of dietary fats, potentially reducing the number of calories absorbed from food.

Promoting fat burning: Other supplements claim to stimulate the breakdown and utilization of stored body fat, potentially aiding in healthy weight loss.

Providing appetite control: While not their primary function, some weight loss supplements may also have appetite-suppressing properties.

In some cases, health and wellness brands combine the benefits of appetite suppressants and weight loss supplements in one handy product, giving customers the best of both worlds when it comes to proper weight management.

How To Choose an Appetite Suppressant

With the abundance of appetite suppressants available on the market, selecting a safe and effective product can be challenging — you can beat the odds by considering a few factors.

1. Before trying any appetite suppressant, it's crucial to consult with a licensed healthcare provider, such as a doctor or registered dietitian. They can evaluate your individual health profile, assess potential risks, and recommend appropriate options.
2. Choose appetite suppressants from well-established and reputable brands that adhere to strict quality control measures and provide transparent information about their products' ingredients and manufacturing processes.
3. Look for products that have been independently tested by third-party organizations to ensure their potency, purity, and safety.
4. Carefully review the ingredient list and dosage instructions on the product label. Be wary of proprietary blends or undisclosed ingredients, as these can make it difficult to assess the safety and efficacy of the product.
5. When trying a new appetite suppressant, start with the lowest recommended dose and gradually increase it if necessary, while monitoring for any potential side effects.
6. Be wary of appetite suppressants that make unrealistic or exaggerated weight loss claims, as these are often unsupported by scientific evidence.

Conclusion: Are Appetite Suppressants Right for You?

Appetite suppressants are a valuable tool in the journey toward weight management, but they are not a one-size-fits-all solution.

The decision to incorporate appetite suppressants into your weight loss strategy should be made in consultation with a healthcare professional, taking into account your individual health profile, goals, and potential risks for undesirable side effects.

While appetite suppressants are meant to help curb hunger and reduce calorie intake, they should be used in conjunction with a balanced diet and regular physical activity for healthy weight loss, and for sustainable and long-term weight management success. 

It's essential to have realistic expectations and understand that these substances are not a magic solution, but rather a potential aid in your overall weight loss efforts.
