Setmelanotide works by increasing the activation of this receptor, leading to reduced hunger, decreased calorie intake, and increased metabolism , all of which could promote weight loss.

Participants also experienced a significant reduction in hunger with no serious treatment-related adverse events reported. Another small study in children, adolescents, and adults found that setmelanotide significantly improved quality of life as early as 5 weeks after starting treatment, which could be related to reduced hunger and body weight.

Side effects: Some of the most common side effects of setmelanotide include injection site reactions, hyperpigmentation , nausea, headache, diarrhea, and stomach or back pain. Fatigue, vomiting, and depression have also been reported. Contraindications: This medication is not recommended for people with renal impairment, and those who are pregnant or breastfeeding.

Effectiveness: One study in 3, people compared the effectiveness of several medications for obesity and found that people taking phentermine lost the highest percentage of body weight over 12 weeks.

Those taking phentermine lost an average of 8. However, keep in mind that these medications are only recommended for short-term use, as you can build up a tolerance after several weeks, resulting in decreased effectiveness.

Please refer to the pharmacotherapy clinical practice guideline to ensure you are utilizing the most up-to-date evidence. Your healthcare team may recommend medications as part of your obesity management plan, alongside behavioural changes.

Before starting a new medication, your healthcare professional will discuss and consider a number of different factors such as your health history, BMI, other complications of obesity, such as type 2 diabetes or high blood pressure and possible side effects. In Canada, four prescription medications are available for the treatment of overweight and obesity.

Wegovy® is a GLP-1 therapy that acts like the natural GLP-1 found in your body. Wegovy® acts on specific neurons in the brain to help you feel more satisfied, reduce hunger, and control cravings. Studies have shown Wegovy® to have beneficial effects on blood pressure, blood sugar, and cholesterol levels.

Wegovy® comes in a single-use pen that patients can use to self-inject once a week. In Canada, Wegovy® is approved to be used with a reduced calorie diet and increased physical activity to improve weight loss in patients with an initial BMI of:. These medicines work on two separate areas of the brain that are involved in controlling eating hunger and cravings.

Contrave® is delivered in the form of an oral tablet; at the maximum recommended dose, two tablets are administered twice daily. In Canada, it is approved for use alongside a reduced-calorie diet and increased physical activity in adult patients with:.

GLP-1 or glucagon-like peptide-1 is a hormone that is found naturally in your body that has effects on appetite and food intake. Saxenda® is a GLP-1 therapy that is similar to the natural GLP-1 found in your body.

Saxenda® is thought to help patients lose weight by decreasing appetite and the amount you eat. Studies with Saxenda® have also shown that it may also improve other health factors beyond weight, including waist circumference, blood sugar, blood pressure and cholesterol levels.

When calorie restriction and cardio workouts leave you tired and hungry, anything that could hurry progress seems worth a try — especially something as easy as a pill.

When it comes to diet pills, there are two types: prescription drugs, and over-the-counter supplements. And they are not created or regulated equally. The Food and Drug Administration has approved five prescription drugs for long-term weight loss based on research about their safety and effectiveness.

Only three of them are pills:. A few other medications — most commonly phentermine — are approved for short-term use. But prescription weight loss medication isn't for everyone. These pills aren't a perfect solution for obesity. Weight loss medications are used along with a healthy diet and exercise regimen that need to be continued after treatment.

Also, side effects are common and can be severe. There are many diet pills available that aren't FDA-approved or -regulated, and there is minimal evidence that they actually work. Since over-the-counter dietary supplements don't have to be vetted for safety or efficacy by the FDA , it's much easier to get them onto shelves and into your medicine cabinet.

In fact, many manufacturers of weight loss supplements don't test their products in humans before taking them to market. What's more, the FDA has warned that some over-the-counter products contain hidden ingredients. These include prescription drugs and controlled substances like sibutramine , which was removed from the market in because it substantially increased heart rate and blood pressure.

So if you're considering a diet pill supplement, there are a few things you might want to know first. These types of diet pills often contain vitamins, minerals, enzymes, and herbs.

The most common ingredients can be found in a database from the National Institutes of Health. One such ingredient is Garcinia cambogia, which comes in products like Hydroxycut and Plexus Slim.

It's supposed to suppress appetite and decrease the number of fat cells your body makes. Though it's considered "fairly safe," there's no evidence that it actually helps with weight loss, and excessive use has been linked to liver problems.

Other diet pills may contain chitosan, from the shells of crabs, lobsters, and shrimp. In theory, it's supposed to bind fat in your digestive tract so your body can't absorb it.

In reality, according to the NIH, the amount of fat it binds is probably not enough to help you lose a significant amount of weight. The most common ingredients are stimulants like caffeine, yerba mate, bitter orange, or guarana. When it comes to the data on these ingredients, there's not a lot to suggest they help in any way with weight loss, said Katherine Zeratsky , a registered dietitian at the Mayo Clinic.

For example, a study found that rats given caffeine burned more calories than rats doing the same amount of exercise without a stimulant. But there is no evidence that the effect carries over to humans. Theoretically, all these ingredients should help with weight loss, but it's extremely difficult to figure out if they work, Zeratsky said.

That's because most diet pills are made up of multiple ingredients and the directions suggest you take them while having a diet that's restrictive in calories. So it's hard to tell whether you lost weight because of the product or because you simply ate fewer calories.

No matter what diet pill ingredient or program you're considering, it's critical that you talk to your pharmacist first, Zeratsky said, especially if you take other medications. Though many of the ingredients are considered safe, they can have toxic effects at high doses. And it's possible that they could interfere with your other medications.

Your pharmacist can walk you through a cryptic ingredient list and point out any red flags.
