Diet pills and weight loss supplements are often touted as quick fixes for weight loss, but do they really work, and are they safe for long-term use? These pills typically work by suppressing appetite or reducing the body's absorption of nutrients. While some people have seen short-term results, the weight often returns, and these pills have not been proven effective for sustained, long-term weight loss. Additionally, they may have dangerous side effects and can be habit-forming, leading to the development of eating disorders. For those looking to boost their metabolism and lose weight, a nutritious diet, regular exercise, and adequate sleep are recommended. Certain foods, like hot peppers, and supplements like caffeine, may also help improve metabolism.

Diet pills suppress appetite and reduce nutrient absorption
Diet pills, also known as appetite suppressants, are a type of weight-loss medication for people with obesity, usually defined as having a body mass index (BMI) of over 30. They work by lessening your appetite or making you feel full faster, thereby reducing your calorie intake and leading to weight loss. While these pills can aid in weight loss, it is important to note that they are most effective when combined with a reduced-calorie diet and regular exercise.
Appetite-suppressant drugs act on noradrenergic and possibly dopaminergic receptors to induce feelings of satiety. Some drugs may also increase serotonin levels by blocking serotonin reuptake or increasing its release. While these drugs can produce significant weight loss compared to a placebo, it is important to be cautious due to their potential for abuse. For example, amphetamine, methamphetamine, and benzphetamine have been associated with abuse.
Prescription appetite suppressants are typically approved for short-term use, often up to 12 weeks, due to their potential for addiction. Examples of these short-term appetite suppressants include benzphetamine, diethylpropion, phendimetrazine, and phentermine. It is crucial to follow the prescribed usage of these drugs to avoid potential dangers. Additionally, individuals with a history of substance use disorder should inform their healthcare provider before starting these medications.
The effectiveness of diet pills in managing weight loss is questionable. While they can suppress appetite and reduce nutrient absorption, the long-term effects on metabolism are unclear. Nutritional deficiencies, such as a lack of calcium, magnesium, zinc, or vitamin C, can impact drug metabolism and absorption. Therefore, it is essential to consult a healthcare professional before taking any diet pills, especially if there are concerns about potential interactions with other medications or nutritional deficiencies.

Weight loss drugs are approved for short and long-term use
Weight loss drugs are approved for short- and long-term use. However, it is important to note that these medications are meant to be used in conjunction with a healthy eating plan and exercise regimen. Even with the use of these drugs, changing how your body burns calories through diet and exercise can help you lose weight.
Some weight management medications are designed for short-term use, such as setmelanotide (IMCIVREE), which is limited to people with specific rare genetic disorders. Other drugs, like phentermine, are approved by the FDA for use for a few weeks, but newer medical guidelines have added it to long-term therapy. Phentermine is the oldest and most widely used weight loss medication, with some patients losing about 5% of their body weight by taking it. However, it is important to note that it has side effects such as headache, overstimulation, high blood pressure, insomnia, and rapid or irregular heart rate.
Other weight loss drugs are approved by the FDA for long-term use. These include orlistat (Xenical, Alli), phentermine-topiramate (Qsymia), naltrexone-bupropion (Contrave), liraglutide (Saxenda), semaglutide (Wegovy), Ozempic, and tirzepatide (Zepbound, Mounjaro). The dosing for some of these drugs includes a long ramp-up period of up to five months to reach the full dosage. It is important to note that obesity is a disease, and no drug can permanently "cure" it.
The amount of weight a person loses depends on the medication they take, their overall health, and other individual factors. While some drugs have been withdrawn due to a lack of efficacy and safety concerns, clinical studies have shown significant weight loss with semaglutide. A 2022 study of 175 individuals showed a 5.9% weight loss at three months and 10.9% at six months. However, drawbacks of semaglutide include high cost, side effects, and the long-term to indefinite length of treatment.

Diet pills can cause dangerous side effects and eating disorders
Diet pills can have dangerous side effects, and their use has been linked to a higher risk of developing an eating disorder. Research has shown that young women who use diet pills and laxatives to control their weight are more likely to be diagnosed with an eating disorder than those who do not. The study, led by Harvard researchers, found that 1.8% of participants without an eating disorder who used diet pills reported receiving an eating disorder diagnosis within one to three years, compared to only 1% of those who did not use these products.
The abuse of diet pills by individuals with eating disorders is well-documented, with prevalence estimates as high as 50%. Diet pill use is associated with various purging behaviours, such as vomiting, laxative use, diuretic use, and emetic use. Additionally, diet pill use is linked to higher BMIs, higher novelty-seeking behaviour, and the presence of anxiety disorders, alcohol abuse or dependence, and borderline personality disorder.
The side effects of diet pills can be severe and include constipation, upset stomach, bloating, diarrhoea, stomach problems, kidney problems or failure, gallbladder issues, pancreatitis, and hypoglycaemia. In some cases, diet pills may even cause thyroid tumours or thyroid cancer. These medications can also increase the risk of weight regain if stopped abruptly.
Given the potential adverse effects, it is crucial for individuals considering weight loss medications to familiarise themselves with the risks. Health care providers do not recommend over-the-counter diet pills or laxatives as a healthy way to manage weight, as they can lead to severe health consequences, including high blood pressure and liver and kidney damage.

Metabolism boosters rarely affect weight loss significantly
While metabolism boosters and supplements promoted as fat busters are often hyped, they rarely have a significant effect on weight loss. The best way to lose weight is by cutting calories and exercising more regularly. It is also important to adopt an eating plan that can be stuck to long-term.
Metabolism is a series of reactions that occur in the body to provide it with energy from the food we eat. It is the process by which the body expends energy and burns calories. Metabolism speed can be increased to a degree by following a proper diet and exercise. For example, eating protein and doing weight training can boost metabolism as the body's metabolism increases whenever it eats, digests, and stores food. A 2012 review of 20 research studies found that capsaicin, a chemical found in hot peppers, may increase the number of calories burned by approximately 50 calories daily, contributing to long-term weight loss. Similarly, a meta-analysis published in Obesity Reviews found that consuming about 250 milligrams of epigallocatechin gallate (the amount in about three cups of green tea) helped burn an average of 100 extra calories a day.
However, it is important to note that these metabolism boosters only lead to small changes in the number of calories burned. Additionally, while some weight loss drugs may help in the short term, the weight tends to return, and some medications are only meant for short-term use. For example, the U.S. Food and Drug Administration (FDA) has approved a few prescription drugs for long-term weight loss use, such as Wegovy, also known as semaglutide, which was approved by the FDA in 2021 for long-term weight management.

Exercise and a healthy diet are key to weight loss and metabolism regulation
While some weight loss drugs may be effective in the short term, the weight tends to return, and the best way to lose weight and regulate metabolism is through a combination of diet and exercise.
Exercise and physical activity are key to weight loss and maintaining a healthy weight. Regular exercise helps burn extra calories and increases metabolic rate, allowing for more flexibility with your diet. Strength training helps build muscle mass, which increases your metabolic rate over time, so your body burns more calories, even at rest. A single strength-training session can increase your metabolic rate for up to 72 hours. Aerobic exercise, such as walking, jogging, or cycling, especially at a low to moderate intensity for 30 minutes or longer, can burn a significant number of calories and help promote a calorie deficit. Regular exercise may also help manage hunger by regulating hunger hormones, preventing overeating and excess snacking.
A healthy diet is also crucial for weight loss and metabolism regulation. Adopting an eating plan that includes whole, minimally processed foods that are high in fiber, protein, and healthy fats can help manage calorie intake without the need for counting calories. Eating more fruits, vegetables, whole grains, and hot peppers can improve metabolism. Additionally, decreasing the consumption of energy-dense, high-calorie, and low-nutrient foods is essential for weight loss and maintaining a healthy metabolism.
Combining modest calorie restriction with exercise is the most effective way to achieve significant and sustainable weight loss. While exercise and diet modifications are crucial for weight loss, they also provide numerous other health benefits, such as improved mental well-being, reduced heart disease risk, and improved cellular health.
