There is also no medical or clinical data to show they work, despite any qualitative endorsement. There are many unwanted side effects to suppressants, and unregulated suppressants are potentially dangerous. Here we look into appetite suppressants in more detail — including why they are not a safe way to manage your weight loss.

Appetite suppressants used to be prescribed to people with a body mass index BMI of 30 or above, or for those with a BMI of 27 or higher if they have other obesity-related risk factors type 2 diabetes and high cholesterol.

They were not designed to be taken for any longer than a year. But, they have experienced a fall from grace in the past decade and are no longer available on prescription. We at The Independent Pharmacy recommend that unregulated ones are avoided — there are plenty of horror stories of people buying dodgy diet pills online.

Reductil was a popular appetite suppressant that contained the active ingredient sibutramine hydrochloride monohydrate. This medicine was discontinued in the UK in A review by the European Medicines Agency suggested a link between taking Reductil and an increased risk of non-fatal strokes and heart attacks.

These risks outweighed the weight-loss benefits achieved with this medicine. People who were taking Reductil were advised to consult with their doctor for alternative weight loss treatments.

Appetite suppressants act on neurotransmitters in the brain. These transmitters are natural chemicals found in nerve cells, which are released from the nerve cells when a neural message is transmitted. Neurotransmitters are then reabsorbed into the nerve cells upon the successful transmission of the message.

Appetite suppressants block two of these neurotransmitters from being reabsorbed into the nerve cell. These are noradrenaline and serotonin. These chemicals are responsible for regulating mood and various other processes.

Preventing these chemicals from being reabsorbed, results in more noradrenaline and serotonin acting in the brain. This has the effect of enhancing the feeling of being full post-eating.

This allows you to feel satisfied for longer after actually consuming less food. However, none of these are medicines, and there is no proof that they actually work.

Appetite suppressants can potentially cause side effects. Medicines and their side effects affect different people in different ways. The following side effects are known to be associated with appetite suppressants. However, because a side effect is listed here, it does not mean that everyone who takes appetite suppressants will experience all, if any, of these side effects:.

Before you start any new treatment, you should always inform your doctor or pharmacist of the medicines you are currently taking, including those bought over-the-counter and any herbal treatments. Appetite suppressants can interact with other medicines, making them potentially ineffective, even dangerous.

They should not be taken at the same time as, or within 2 weeks of any of the following medications:. Appetite suppressants should not be used at the same time as other medicines that increase serotonin levels in the brain. Doing so may result in a side effect called serotonin syndrome, which can be serious.

The following medicines can increase the risk of experiencing the side effects associated with appetite suppressants:. On TikTok, videos documenting Ozempic-assisted weight loss have racked up hundreds of millions of views. Elsewhere on the internet, speculation that Ozempic has catalyzed the drastic body transformations of celebrities runs wild.

A number of musicians and actors told the Guardian that they personally knew high-profile people in their industries using Ozempic, although none would go on record. Ghiyam has joined in on the publicity push himself, with his own informational OzempicWeightLoss TikToks reeling in hundreds of thousands of views.

Ozempic is also advertised regularly on TV: the ubiquitous commercials feature various characters who, having stabilized their blood sugar levels, are living healthy, active lives.

But the ad mentions weight loss only as an afterthought. One of its corollary effects however, is that it makes patients want to eat less. And so doctors are increasingly prescribing the drug off-label, purely for its effect helping people lose weight.

Trish Wheeler is one of thousands of Ozempic users. For years, she had exercised and eaten right. But as she got a little older, and her body transitioned into menopause, she found her usual habits were no longer doing the trick. She managed to lose about 20lbs 9kg before her doctor prescribed a new treatment: Ozempic.

But Ozempic is not a miracle. The drug works because Semaglutide simulates a hormone called GLP-1 that regulates blood sugar levels. If blood sugar rises, the hormone tells the body to produce more insulin, which lowers blood sugar levels in turn. This method of action has made GLP-1 a game changer in the management of type 2 diabetes, but the same hormone has also been shown to slow down the passage of food from the stomach to the small intestine, which can increase a feeling of satiety by making patients feel fuller faster.

According to data from the Mayo Clinic , studies found that patients combining weekly Semaglutide injections with healthy lifestyle changes eating a balanced diet, exercising regularly and so on resulted in weight loss of about The worry is that the off-label use of Ozempic for weight loss is creating shortages for people who rely on the drug in treating type 2 diabetes.

Isabelle Kenyon is a founder and CEO of Calibrate, a telehealth weight loss startup that has more than 25, members, all of whom are using GLP-1s, including Semaglutide, for weight management. They have been fretting about a Semaglutide scarcity for the past few months.

Online, some doctors say the drug is on back order through December. Novo Nordisk responded to the uptick in off-label prescribing by introducing a new, rebranded drug, called Wegovy: a chemically identical Semaglutide injection, offered at higher doses, targeted specifically for obesity and weight management.

Now, Wegovy itself is in short supply. The FDA reports that the distribution of Wegovy, in various dosages, has been temporarily paused. This pause comes at what is, arguably, an opportune time. Between the media hype, the TikTok trends, the targeted ads and the wall-to-wall blitz of TV commercials, GLP-1s seem to have exploded overnight.

The treatment is not merely mechanical, but physiological. Ghiyam has heard similar reports from his patients. But just as weight loss was initially a byproduct of using GLP-1s for diabetes treatment, these side effects may not be side effects at all, but the cause of the weight loss.

Simply put, Ozempic, and similar GLP-1s, may work because they make food or at least certain types of food taste disgusting. A paper in the journal Neuropharmacology found that this feeling of nausea was integral to reducing food take.

More recent research has shown that glucagon-like peptide-1 plays a key role in taste perception. When Trish Wheeler started taking the drug, she found her physical reactions to food shifted almost immediately. Online, forums are chock full of stories from Ozempic users whose relationship with food has changed, not only physiologically, but psychologically.

There is, perhaps, something sinister, and even a little sci-fi, about a wildly popular weight loss treatment that works, whether in whole or in part, by making food itself disgusting.

But however weird they may seem, these kinds of chemical mechanics are not entirely uncommon. The antidepressant Wellbutrin has also been long-prized for its off-label ability to make cigarettes taste disgusting, a side effect that resulted in the same chemical bupropion being rebranded as Zyban, an FDA-approved smoking cessation aid.

For an easy way to introduce tofu in your diet , try adding it to your next healthy stir-fry or in a grain bowl with tofu and veggies. Tofu is high in an isoflavone called genistein, which, according to a study in Advances in Nutrition , has been shown to suppress appetite and lower food intake.

Ever notice how when you eat sushi it doesn't seem to take as much food to fill you up? Well, part of that is because of the healthy fish in sushi, but the other part is due to that spicy green stuff: wasabi!

According to a study in the journal Foods , the spiciness in wasabi makes it a natural appetite suppressant and anti-inflammatory. If you're not a coffee drinker and get sick of water easily, try a natural appetite suppressant tea. Green tea can help you stave off hunger that results in mindlessly snacking.

According to a research report in Appetite , the caffeine and catechins in green tea are the reason. They suppress your appetite and make you feel full. Packing over 5 grams of protein and 4 grams of dietary fiber in a half-cup serving, oatmeal is a nutritionally rich food you can easily incorporate in your life.

The high fiber content helps slow digestion which prevents uncomfortable spikes in blood sugar. And while oats are also high in carbohydrates, the carbs in oatmeal provide energy and make you feel fuller for longer.

According to research in the American College of Nutrition , oatmeal kept participants from feeling hungry for longer than regular breakfast cereals.

They can be eaten alone, mixed in a stew, or tossed in a salad. A study in the journal Applied Physiology, Nutrition, and Metabolism considered the effect on appetite of eating lentils and other beans before meals. Lentils were found to be a better appetite suppressant and resulted in less food intake than chickpeas in the study.

If you're looking for a highly nutritious food that will fill you up for hours, you can't beat green leafy vegetables — they're the ultimate natural appetite suppressant.

Fibrous greens eaten raw or gently sautéed with a little olive oil are a delicious way to keep hunger at bay. A study in Plant Foods for Human Nutrition found that foods that are high in thylakoids, like spinach, kale, broccoli, and mustard greens, are particularly beneficial in reducing hunger.

Each 3-ounce serving of fresh salmon contains nearly 17 grams of protein. Not a fan of salmon, tuna and herring have similarly high levels of protein and omega-3s.

Here's a super-easy way to make anything you're eating a natural appetite suppressant: Next time you have cereal, oatmeal, fruit, or even coffee, sprinkle some cinnamon on it.

A research article on the medicinal properties of cinnamon found that cinnamon helps lower your blood sugar levels which helps to control your appetite.

Another protein powerhouse, just one 7-ounce container of plain Greek yogurt contains a whopping 20 grams of protein. In addition to making you feel full, other Greek yogurt benefits include a healthy gut, strong bones, and a boosted immune system. Greek yogurt is better than skim or whole milk at suppressing appetite, according to an article in Applied Physiology, Nutrition, and Metabolism.

When it comes to hot sauce as an appetite suppressant, the hotter you can go the better. So get some Tabasco or any hot chili sauce and sprinkle some heat on your burrito, scrambled eggs, or even soup! According to research reviewed in the journal Appetite , consumption of hot sauce containing hot chili peppers will help you stay fuller for longer.

Not only that, the spiciness keeps you from eating too much. With a nutritional mix of soluble fiber and essential fatty acids, flax seeds are the perfect addition to your yogurt, smoothie, or salad.

Just make sure you grind them first because the human body can't digest whole flax seeds. As a natural appetite suppressant, they'll help you stay full and fueled.

Although the research on flax seeds and satiety is limited, a review in the journal Phytotherapy Research found that the available studies suggest a potential role of flax seeds in decreasing appetite and hunger.

If you want to keep the hunger monster away, eat a small salad before you sit down for a meal. Since it takes about 20 minutes for your stomach to signal to your brain that you're full, starting with a small salad before your meal is a perfect way to get a head-start on that hunger signal.

In a study in the Journal of the Academy of Nutrition and Dietetics , participants who ate a salad before a meal were less hungry and ate less of the meal than participants who did not have a salad as a first course.

A salad can also be a great way to up your veggie intake. Protein is known as an appetite suppressant, but it seems that whey protein is especially good.

A review article on the effects of whey protein on appetite found that consuming this protein supplement in shakes or smoothies is effective a suppressing hunger. A study in the journal Nutrients on the impact of a high-protein meal replacement on appetite found that consuming a high-protein meal replacement instead of a standard North American breakfast prior to exercise resulted in a greater suppression of hunger both during and after exercising.

Was this page helpful? How long you take a weight-loss drug depends on whether the drug helps you lose weight. If you've lost enough weight to improve your health and you haven't had serious side effects, your health care provider may suggest that you take the drug long term.

They may switch you to a different weight-loss drug. Six weight-loss drugs have been approved by the U.

Food and Drug Administration FDA for long-term use:. Most prescription weight-loss drugs work by making you feel less hungry or fuller. Some do both. The exception is orlistat. It affects the way your body absorbs fat. Bupropion-naltrexone is a combination drug.

Naltrexone is used to treat alcohol and opioid addiction. Bupropion is a drug to treat depression, called an antidepressant, and a drug to help people stop smoking, called a quit-smoking aid. Like all antidepressants, bupropion carries a warning about suicide risk.

Bupropion-naltrexone can raise blood pressure. So your provider will need to check your blood pressure regularly at the start of treatment. Common side effects include nausea, headache and constipation.

Liraglutide also is used to manage diabetes. It's given as a daily shot. Nausea is a common complaint. Vomiting may limit its use. You also can get orlistat in a reduced-strength form without a prescription Alli. Orlistat can cause side effects such as passing gas and having loose stools.

You need to follow a low-fat diet when taking this medicine. In rare cases, people have had serious liver injury with orlistat.

But researchers haven't found that the drug causes liver injuries. Phentermine-topiramate is a combination of a weight-loss drug called phentermine and an anticonvulsant called topiramate. Phentermine has the potential to be misused because it acts like a stimulant drug called an amphetamine.

Other possible side effects include an increase in heart rate and blood pressure, insomnia, constipation, and nervousness.

Topiramate increases the risk of birth defects. Phentermine by itself Adipex-P, Lomaira also is used for weight loss. It's one of four similar weight-loss drugs approved for use for less than 12 weeks, called short-term use.

The other drugs in this group aren't often prescribed. Semaglutide also is used to help control type 2 diabetes. You take it as a weekly shot to manage obesity. The FDA has approved setmelanotide only for people age 6 and older who have obesity due to one of these rare inherited conditions:.

To take the drug, you'll need to have test results that show you have one of these conditions. Setmelanotide doesn't treat any of the gene problems that cause these conditions.

But it can help you lose weight. It can lessen your appetite and make you feel fuller. And it may help you burn calories while your body is at rest. Never give setmelanotide to a child under 6 years old.

It can cause newborns and babies to have dangerous reactions. Weight-loss drugs aren't an easy answer to weight loss. But they may help you make the lifestyle changes that you need to practice to lose weight and improve your health. There is a problem with information submitted for this request.
