The prevalence of obesity has increased drastically in recent years. Along with this, the use of weight loss medications has also grown. These medications claim to help people lose weight by decreasing appetite, increasing metabolism, or suppressing fat absorption.
Weight loss medications can have side effects such as nausea, diarrhoea, and constipation. They also may lead to serious health problems such as high blood pressure and liver damage. In addition, one gets dependent on them as they are addictive, which can lead to drug dependence and abuse.
This article will scientifically look at weight loss medications, their effectiveness and potential risks.
Weight Loss Medications: An Overview
Weight loss medications are prescription medications that can assist individuals in achieving and maintaining a healthy weight. They work in different ways, depending on the components. For example, some drugs suppress appetite, while others target fat storage and metabolic pathways.
Some of the most commonly prescribed weight loss medications include appetite suppressants like lorcaserin, naltrexone-bupropion, orlistat, liraglutide, and stimulants like phentermine. In addition, drugs such as Contrave and Saxenda have both appetite-suppressant and metabolism-enhancing effects.
Research shows taking prescription weight management medications as part of a lifestyle program can result in losing 3% to 12% more of the starting body weight. Certain medications can lead to a weight loss of 10% or more, but results may differ. However, one can lose the same weight without fearing complications by following a healthy and balanced diet and making some lifestyle changes.
Weight Loss Medications: What Do They Do?
Weight loss medications can help people manage their weight. Yet, it’s essential to understand what they do and how they work before taking them. Generally, weight loss medications work by:

Decreasing Appetite
Some medications can make you feel less hungry and make it easier to stick to a calorie-restricted diet. Alternatively, you can increase your intake of fibre-rich foods like fruits, vegetables, and whole grains to reduce your appetite. These foods keep you full for extended periods, reducing the urge to snack. Additionally, drinking plenty of water and getting enough sleep can also help reduce appetite.
Increasing Satiety
Some medications can make you feel fuller for longer, helping you eat less. However, protein-rich foods can also increase satiety. You can eat protein-rich foods like lean meats, fish, eggs, and beans. These foods make you feel fuller for longer, reducing the urge to eat more. Eating slowly and mindfully can also increase satiety, giving your body enough time to signal your brain that you’re full.

Boosting Metabolism
Some medications can increase your body’s metabolism, helping you burn more calories throughout the day. However, exercise can boost your metabolism and build lean muscle mass. For example, aerobic activities like running, biking, or swimming can increase metabolism for several hours after exercise. In addition, strength training exercises like weightlifting or bodyweight exercises can also help build lean muscle mass, which increases metabolism at rest.
Reducing the Absorption of Dietary Fat
Some medications can reduce the amount of dietary fat your body absorbs, leading to fewer calories stored as fat. To reduce the absorption of dietary fat, reduce your intake of high-fat foods like fried foods, fast foods, and processed snacks. Additionally, eating more fibre-rich foods can help reduce the absorption of dietary fat. Soluble fibre, in particular, can bind to dietary fat in your gut, making it less available for absorption.
Summary
Weight loss medications can help individuals manage their weight by decreasing appetite, increasing satiety, boosting metabolism, or reducing the absorption of dietary fat. However, one can achieve similar results through natural ways such as consuming a fibre-rich diet, protein-rich foods, exercising, and reducing the intake of high-fat foods. These dietary and lifestyle changes can help individuals reduce their appetite, increase satiety, boost metabolism, and reduce the absorption of dietary fat without relying on weight loss medications.
Types of Weight Loss Medications
Different weight loss medications that work in various ways are available today.
Prescription Medications
Some medications are only available with a prescription, while others may be available over the counter. Some prescription medications are approved by the Food and Drug Administration (FDA) for treating obesity and controlling weight. Examples include bupropion, orlistat, and phentermine.
OTC Medications
Some weight loss medications are available over the counter, meaning you don’t need a prescription to purchase them. These medications typically contain caffeine, guarana, and green tea extract to boost energy and metabolism. Examples of OTC medications include green coffee extract and garcinia cambogia.
A meta-analysis revealed that green coffee extract significantly reduced body mass index. However, Green coffee extract in OTC weight loss medicines can be unsafe, as it can cause side effects such as anxiety, headaches, and irregular heartbeat. Additionally, the quality and purity of the extract can be questionable.
Over-the-counter weight loss medications can adversely affect the body. These medications may lead to high blood pressure, heart palpitations, insomnia, and gastrointestinal problems. In addition, they can clash with other medicines, leading to adverse impacts on the body. Moreover, they may contain ingredients not adequately tested or regulated by the FDA, which can be detrimental. Lastly, these medications are shortcuts and cannot be healthy. Sustainable weight loss must happen through healthy eating and exercise.
Herbal Supplements
Herbal supplements often get marketed as natural weight loss aids. However, the FDA does not approve them. Examples of herbal supplements include Hoodia Gordonii, green tea extract, and bitter orange.
A study shows green tea extract improves body composition by decreasing exercise-induced changes in weight, waist-to-hip ratio, body mass index, and body fat percentage. But again, herbal supplements are not FDA regulated. Nevertheless, green tea extracts are a regular feature in herbal supplements for weight loss. Still, it is not entirely safe, and the quality and purity of the extract may need to be more consistent. In addition, it can lead to adverse health effects of green tea extract, including liver toxicity, kidney failure, etc.
Some supplements contain high levels of caffeine, which can cause insomnia, anxiety, and other side effects. Also, studies show that there is currently insufficient evidence supporting herbal medicines for weight loss.

Consulting a doctor before starting a weight loss medication regimen is extremely essential. It is because improper use can lead to potentially dangerous outcomes.

Weight loss medications do not suit everyone, and some groups of people should avoid taking them altogether. For example, pregnant or breastfeeding women should not use weight loss medications as it can harm the baby.

HealthifyMe Suggestion
Weight loss medications are often quick and easy solutions for shedding pounds. However, they only offer short-term weight loss; one should not rely on them as the only answer to achieving weight loss goals. Additionally, healthy eating and regular exercise are necessary for success. Weight loss medications do not address the root cause of weight gain. Therefore, identifying and addressing underlying factors is crucial for long-term weight loss.

However, whether you take weight loss medication or not, changing your lifestyle is the key to weight loss and management.
