What are Appetite Suppressants?

If you're looking to lose weight, having an appetite suppressant up your sleeve can be a major benefit, offering a way to curb those pesky hunger pangs and reduce calorie intake. But what exactly are appetite suppressants, and how do they work?

Appetite suppressants, as the name suggests, are substances that can help reduce appetite, leading to a decrease in food consumption and potentially aiding in weight loss efforts. They work by influencing various mechanisms that regulate hunger and satiety signalling in the body.

Common Mechanisms of Action:

  • Neurotransmitter Modulation: Some appetite suppressants influence the levels of neurotransmitters involved in appetite control, such as serotonin and norepinephrine. By increasing these neurotransmitters, they can promote feelings of fullness and reduce hunger cues.

  • Gut Hormone Regulation: Other appetite suppressants target gut hormones, such as ghrelin and cholecystokinin (CCK). Ghrelin is known to stimulate appetite, while CCK promotes satiety. Appetite suppressants can either reduce ghrelin levels or enhance CCK action, leading to reduced hunger and increased satiety.

  • Metabolic Effects: Some appetite suppressants exert their effects by influencing metabolism. By increasing energy expenditure or reducing nutrient absorption, they can indirectly reduce appetite and promote weight loss.

Types of Appetite Suppressants:

Appetite suppressants come in various forms, including prescription medications, over-the-counter supplements, and natural substances.

  • Prescription Appetite Suppressants: These medications are typically prescribed by healthcare professionals for individuals with obesity or weight-related health conditions. They work through various mechanisms and may have stronger effects than over-the-counter options.

  • Over-the-Counter Appetite Suppressants: These supplements are readily available without a prescription and often contain ingredients like caffeine, fibre, or green tea extract. Their effectiveness may vary depending on the individual and the specific ingredient.

  • Natural Appetite Suppressants: Certain foods and compounds have been shown to have appetite-suppressing properties. Examples include protein-rich foods, fibre-rich foods, and capsaicin, the compound that gives chilli peppers their heat.

Effectiveness and Considerations:

Appetite suppressants can be an effective tool for weight loss when used as part of a comprehensive approach that includes diet and exercise. However, it is important to remember that they are not a magic bullet and should be used with caution and under the guidance of a healthcare professional.

Potential Side Effects:

Appetite suppressants can cause a range of side effects, including dry mouth, constipation, nausea, headache, and insomnia. Some appetite suppressants may also interact with medications, so it is crucial to inform your healthcare provider about all supplements and medications you are taking. We will come onto side effects in more detail later.


Appetite suppressants offer a potential tool for weight loss, but it is essential to approach them with caution, understanding their mechanisms of action, potential side effects, and interactions with medications. When used responsibly under the guidance of a healthcare professional, appetite suppressants can complement a healthy diet and exercise program to support weight loss goals.

How do Appetite Suppressants Work?

The science behind appetite suppressants is multifaceted, involving intricate mechanisms that impact physiological and neurological processes. In this section, we delve into the scientific principles that underlie appetite suppressants and elucidate how they work to assist in weight control.

  1. Neurotransmitter Modulation: Appetite suppressants often target neurotransmitters, the chemical messengers in the brain that regulate various physiological functions, including hunger. Serotonin, in particular, plays a crucial role. Appetite suppressants can enhance serotonin levels, creating a sense of satiety and reducing the desire to eat excessively. This modulation contributes to a more controlled appetite and, subsequently, weight management.

  2. Leptin and Ghrelin Regulation: Leptin and ghrelin are hormones that play pivotal roles in appetite regulation. Leptin signals the brain when the body is satiated, while ghrelin stimulates hunger. Some appetite suppressants work by modulating these hormonal signals, enhancing leptin sensitivity and reducing ghrelin production. This intricate hormonal balance contributes to a regulated appetite and better control over food intake.

  3. Central Nervous System Impact: Certain appetite suppressants act on the central nervous system, influencing specific areas of the brain responsible for appetite control. These medications can alter neuronal activity, resulting in decreased hunger signals and a diminished perception of food rewards. By targeting neural pathways associated with appetite, suppressants contribute to reduced cravings and a lower overall food intake.

  4. Delaying Gastric Emptying: Some appetite suppressants influence the rate at which the stomach empties its contents into the small intestine. By slowing down gastric emptying, these medications create a feeling of fullness that persists for a more extended period after a meal. This delayed emptying contributes to reduced hunger and a decreased inclination to consume additional calories.

  5. Increased Energy Expenditure: Certain appetite suppressants can elevate energy expenditure, promoting weight loss by burning more calories. This increase in energy expenditure is often accompanied by a boost in metabolic rate, contributing to a more efficient calorie-burning process and aiding in weight management efforts.

  6. Glucose Regulation: Blood sugar levels also play a role in appetite regulation. Some appetite suppressants work by stabilizing blood glucose levels, preventing the rapid spikes and subsequent crashes that can trigger hunger. By maintaining steady blood sugar levels, these medications contribute to a more controlled appetite and reduced cravings.

  7. Emotional Eating and Stress Reduction: Psychological factors, including stress and emotional eating, can significantly impact appetite. Certain appetite suppressants address these factors by influencing mood-regulating neurotransmitters such as dopamine and norepinephrine. By mitigating stress and improving mood, these medications contribute to a reduction in emotional eating and cravings.

The science behind appetite suppressants is a fascinating interplay of neurobiology, hormonal regulation, and physiological responses. Understanding these mechanisms sheds light on how these medications can assist individuals in their weight management journey. It is crucial to note that the use of appetite suppressants should be approached with caution and under the guidance of healthcare professionals, as individual responses may vary, and potential side effects need to be considered. As science continues to unravel the complexities of appetite regulation, the development of more targeted and personalised approaches to weight management remains an exciting avenue for future research and innovation.The risk of serious side effects with appetite suppressants is low, but if you experience any of the more common side effects, it is worth speaking with your Doctor, GP, or healthcare provider straight away.

It is worth bearing in mind if you want to try an appetite suppressant, doing as part of a balanced diet when you do eat and try to eradicate junk food as part of your overall weight loss journey. And don't expect immediate results; be patient - appetite suppression is one part of the overall plan but losing weight can take time. Fat burners may also help (see our top five appetite suppressants' section as these can be included into powerful weight loss supplements), but relax, take your time and maybe throw a bit of physical activity into the mix as well and you'll be shredding the kilos in no time!

Side effects of Appetite Suppressants

Appetite suppressants have emerged as a popular weight management tool, offering a potential solution to curb hunger pangs and reduce calorie intake. However, it's crucial to approach these supplements with caution, as they can come with a range of potential side effects. Understanding these side effects empowers you to make informed decisions about their use, seek medical attention if necessary, and manage your weight management journey effectively.

Our recommended appetite suppressants usually have minimal or no side effects.

Common Side Effects of Appetite Suppressants:

  1. Digestive Issues: Gastrointestinal upset is a common side effect of appetite suppressants, manifesting as nausea, vomiting, diarrhea, and abdominal discomfort. These symptoms are often transient, diminishing as the body adjusts to the supplement. However, if they persist or become severe, it's essential to consult a healthcare professional.

  2. Central Nervous System Effects: Some appetite suppressants can affect the central nervous system, leading to side effects such as jitters, anxiety, insomnia, and headache. These side effects are more common with stimulant-based appetite suppressants and may be dose-dependent. Individuals with underlying anxiety or sleep disorders should exercise caution when considering stimulant-based appetite suppressants.

  3. Dry Mouth: Appetite suppressants can cause dry mouth, a discomforting side effect that can make it difficult to swallow or speak. This dryness stems from the suppression of salivary gland activity. To alleviate dry mouth, drink plenty of water, suck on sugar-free hard candy, or use a saliva substitute.

  4. Cardiovascular Effects: Some appetite suppressants may have an impact on the cardiovascular system, potentially affecting blood pressure and heart rate. Individuals with pre-existing cardiovascular conditions should consult their healthcare provider before using appetite suppressants to ensure their safety.

  5. Allergic Reactions: While rare, allergic reactions to appetite suppressants can occur, manifesting as rashes, hives, itching, and swelling. If you experience any of these symptoms, discontinue the supplement immediately and seek medical attention.

Individual Variability and Monitoring:

It's important to remember that individuals respond differently to supplements, and side effects can vary in severity and frequency. Close monitoring of your body's response to any supplement is crucial. If any side effects become bothersome or interfere with your daily life, consult your healthcare provider to discuss alternative options. It's also worth monitoring your body mass index so you can keep track of your progress, it helps to be boosted by ongoing steps.

Further Reading

If you have an underlying medical condition, such as high blood pressure, insulin sensitivity, heart disease or suicidal thoughts, make sure you speak with a Doctor before taking any supplements. Diet pills can work but it is always best to check to be safe if you have any medical conditions, a health condition, or if you see any side effects or adverse effects.

It is always worth checking with the Therapeutic Goods Administration for any questions or concerns with drugs or supplements of any kind. Use appetite suppressants and weight loss supplements as part of overall lifestyle changes. Weight loss medications can work well but use them in conjunction with a low-calorie diet and exercise and you should see your energy levels boosted and your waist circumference reduced! But don't expect miracle results if you don't make a little bit of an extra effort.

Have a systematic review of your whole lifestyle if you are thinking of trying weight loss supplements, appetite suppressants etc. Think about what you are eating, try and have a bit of exercise in your daily routine, and don't eat junk food. Try to stick to a low-calorie diet to help reduce your body weight - exercise, a healthy lifestyle and watching your food intake will help weight loss supplements work better.

The History of Appetite Suppressants

The quest for effective weight management has driven innovations in the field of appetite suppressants throughout history. From ancient herbal remedies to modern pharmaceutical breakthroughs, the evolution of appetite suppressants to reduce body weight reflects a fascinating intersection of science, culture, and the relentless pursuit of healthier living. In this article, we embark on a historical journey, tracing the development of appetite suppressants from their ancient roots to contemporary formulations.

  1. Ancient Remedies: The history of appetite suppressants can be traced back to ancient civilisations where herbal remedies were often used to control hunger. For instance, ancient Egyptians consumed infusions of flaxseed to create a feeling of fullness, while Greek and Roman physicians recommended extracts of seaweed and various plant fibres for appetite control. They also used to have a healthy diet with may have helped (processed food was not a thing back then!)

  2. Ephedra and Ma Huang: In more recent history, the use of ephedra and Ma Huang gained popularity. These plants contain the alkaloid ephedrine, which has stimulant properties and was used as a key ingredient in appetite suppressant formulations. Ephedrine-based products saw widespread use, particularly in the early to mid-20th century.

  3. Amphetamines and World War II: Amphetamines, originally developed for medical purposes, found a new application during World War II. Soldiers used amphetamines to stay awake and alert, inadvertently discovering their appetite-suppressing effects. This led to the post-war popularity of amphetamines as weight loss aids, with notable formulations like Dexedrine emerging in the market.

  4. Fen-Phen and the 1990s: In the 1990s, the combination of fenfluramine and phentermine, commonly known as Fen-Phen, gained popularity as a potent appetite suppressant. However, due to reported cases of serious side effects, including heart valve issues, Fen-Phen was withdrawn from the market in the late 1990s. This event underscored the importance of rigorous safety testing in the development of appetite suppressants. The active ingredient in many appetite suppressants before the year 2000 were questionable at best. The Drug Administration had to keep a close eye on manufacturers and clinical trials; luckily we are in a much better and safer position now.

  5. Sibutramine and Its Withdrawal: Sibutramine, another notable appetite suppressant, was introduced in the late 20th century. It worked by inhibiting the reuptake of neurotransmitters, affecting appetite control. However, concerns about cardiovascular risks led to its withdrawal from the market in 2010, highlighting the ongoing challenges in balancing efficacy with safety in appetite suppressant development.

  6. Phentermine and Topiramate Combination: In more recent years, the combination of phentermine and topiramate has emerged as an FDA-approved appetite suppressant. This combination addresses appetite control through the central nervous system and has shown efficacy in promoting weight loss. Its approval reflects the ongoing efforts to develop safer and more targeted appetite suppressant options.

  7. GLP-1 Receptor Agonists: Modern approaches to appetite suppression include the use of GLP-1 receptor agonists, originally developed for diabetes management. Medications like liraglutide have demonstrated appetite-suppressing effects, leading to their adoption in weight management programs.

Natural Appetite Suppressants

It's worth also looking at natural appetite suppressants. If taken in conjunction with our top recommended products above, you'll be laughing all the way to the jean shop for a new pair!

When thinking about natural appetite suppressants to work in partnership with the dietary supplements we have listed above, consider the following:

1. Protein-Rich Foods: Protein is a macronutrient that plays a crucial role in appetite suppression. Studies have shown that high-protein meals can promote satiety and reduce overall calorie intake. Incorporate protein-rich foods like lean meats, fish, eggs, beans, and lentils into your diet to feel fuller for longer.

2. Fibre-Rich Foods: Fibre is another macronutrient that contributes to satiety and appetite control. Fibre adds bulk to meals, slowing down digestion and promoting feelings of fullness. Include fibre-rich fruits, vegetables, whole grains, and legumes in your diet to curb hunger and support weight management.

3. Non-Starchy Vegetables: Non-starchy vegetables are low in calories and packed with fibre, making them excellent allies in appetite suppression. These vegetables, such as broccoli, carrots, spinach, and cucumbers, can be enjoyed in large quantities without adding significant calories to your diet.

4. Healthy Fats: Healthy fats, such as those found in avocados, nuts, seeds, and olive oil, can promote satiety and reduce hunger. These fats slow down the absorption of sugar into the bloodstream, preventing blood sugar spikes that can trigger hunger pangs.

5. Water: Water often gets overlooked as an appetite suppressant, but it plays a crucial role in feeling full. When you feel thirsty, your body may misinterpret those signals as hunger. Drinking plenty of water throughout the day can help you distinguish between hunger and thirst, potentially reducing overall calorie intake.

Additional Tips for Natural Appetite Suppression:

  • Mindful Eating: Practice mindful eating by paying attention to hunger cues, eating slowly, and savouring each bite. This conscious approach can help you recognize fullness signals and prevent overeating.

  • Regular Meals and Snacks: Avoid skipping meals, as this can lead to increased hunger and overeating later in the day. Aim for regular meals and healthy snacks to maintain stable blood sugar levels and prevent excessive hunger pangs.

  • Adequate Sleep: Sleep deprivation can disrupt hormones that regulate appetite, leading to increased hunger and cravings. Aim for 7-8 hours of quality sleep each night to support optimal weight management.
