How Did We Rank The Top Weight Loss Pills?
While weight loss pills aren’t necessarily healthier when they have natural ingredients, we highly recommend finding a brand with natural ingredients. A non-synthetic ingredient reduces your overall environmental impact and has a lower likelihood of irritation. You also won’t need to worry about the possible side effects of consuming artificial colors, fillers, and chemicals.
Exercise a healthy dose of skepticism if a company touts a proprietary formula. This tactic is often a fancy way for a manufacturer to avoid disclosing its ingredients. Make sure you know all the ingredients you’re putting in your body before buying a weight loss pill.
Always check out customer reviews before buying any diet pill to help you lose weight. Other users can provide valuable insights into the pros and cons and warn you of side effects. While customer reviews shouldn’t make or break your purchase, they can go a long way in shaping your opinion about a specific weight loss drug.
The Food and Drug Administration (FDA) does not regulate the statements that supplement manufacturers put on bottles. Currently, the only FDA-approved weight-loss drug for children is Alli (Orlistat). Ask your doctor about the long-term health effects of weight loss supplements before starting a new diet or taking supplements.
Price / Guarantee
The price of guaranteed weight loss pills vary with the quality of ingredients and the number of pills in a bottle. Most companies offer enough weight loss pills for one month and charge $40 to $60 per bottle. Some places offer “buy one, get one free” deals and money-back guarantees so that you can save money on your initial purchase.
Types of Weight Loss Pills
Thermogenic Fat Burners
Thermogenesis means heat-producing. Your body naturally generates heat to burn calories and absorb nutrients. Some supplements offer thermogenic weight loss pills that speed up your metabolism and its fat-burning capabilities.
Most fast weight loss pills use green tea or caffeine to activate thermogenesis. These stimulants increase adrenaline in the bloodstream and coax your fat cells into releasing fatty acids for energy. Some other thermogenic ingredients include raspberry ketones, capsaicin, garcinia cambogia, and yohimbine. If you need recommendations, you can check out Discover Magazine for a list of the best fat burners to help you lose weight.
Carb blockers zig where other weight loss supplements zag. They prevent your body from digesting carbohydrates, thanks to a group of compounds known as alpha-amylase inhibitors. You can find these compounds in beans and wheat flour.
Carb blockers stop your digestive system from breaking down complex carbs, such as potatoes, pasta, and bread. These foods continue through the stomach and large intestines without your body absorbing them. The inhibitive effect means carbs wouldn’t contribute calories to your diet.
Appetite suppressants help people feel full when they’re not. It’s a useful weight loss option if you find yourself continuously overeating because you feel empty. Some of the most popular appetite suppressants include glucomannan, green tea extract, garcinia cambogia, and conjugated linoleic acid.
Caffeine is arguably the most common ingredient in appetite suppressants. It works by influencing your body’s ghrelin production. This hormone stimulates your appetite and tells your brain to increase food intake. Caffeine dulls these signals so that you can take control of your hunger and health.
Most Popular Weight Loss Pill Ingredients
Glucomannan is a natural dietary fiber that comes from konjac root, also known as elephant yam. The satiating ingredient absorbs water and forms a dense fiber in the stomach. The appetite suppressant has even earned the nickname “the broom of the intestines.”
Green Tea Extract
Green tea extract contains several useful compounds, including antioxidants and caffeine. It helps people boost their energy levels and metabolic rate, making it easier to get daily exercise and burn calories. The supplement also tamps down the appetite so that you won’t deal with hunger pangs.
Green Coffee Bean Extract
Green coffee bean extract comes from unroasted coffee beans. The popular supplement provides numerous health benefits, including improved cholesterol and blood pressure levels. Researchers believe the high concentration of chlorogenic acids is the main reason it can help people cut weight.
Garcinia Cambogia Extract
Garcinia cambogia comes from the Malabar tamarind, a tropical fruit from Indonesia. Scientists say the extract may help people control their hunger and lower blood sugar levels. The main ingredient is hydroxycitric acid, which encourages the body to use stored fat for energy.
Conjugated Linoleic Acid
Conjugated linolenic acid (CLA) comes from grass-eating animals, such as deer and goats. While CLA has many varieties, C9 t11 is the one you’re most likely to find in your weight loss products. Studies link CLA to superior fat burning and weight loss.
A raspberry ketone is a natural molecule found in blackberries, cranberries, and other fruits. Raspberry ketone has gained recent attention for its weight loss properties. Scientists discovered that the molecule helps mice increase fat breakdown, regulate their metabolism, and control blood sugar levels.
Forskolin comes from the Indian Coleus plant, which primarily grows in India, Nepal, and Thailand. Research suggests that it can help treat glaucoma, obesity, and heart conditions. A small study found that men who took 250mg of forskolin for three months lost more weight than men in the placebo group.
Prescription Weight Loss Pills To Consider
Orlistat (Alli) is the OTC alternative to Xenical. The 60mg pill is ideal for adults with BMIs above 25 who plan to adopt a low-fat and low-calorie diet. Orlistat decreases the amount of fat people can absorb after eating.
The enzyme lipase breaks down fat when it reaches your intestines. Orlistat blocks lipase, so the body can’t store the fat for future energy. Orlistat also inhibits your body from absorbing soluble vitamins A, D, E, and K.
Take the FDA-approved weight loss pill up to three times a day for optimal results. A doctor may recommend consuming Orlistat 30 to 60 minutes before your next meal. Side effects may include soft stools and gassiness.
Contrave is a prescription weight loss drug from Currax Pharmaceuticals. The pill can eliminate hunger pangs and control cravings, thanks to a mixture of two medicines, naltrexone and bupropion. Naltrexone is a doctor-approved drug for treating alcohol and opioid addiction, while bupropion helps with depression.
Currax Pharmaceuticals has completed three long-term studies testing Contrave. One year-long trial found that 46% of subjects lost at least 5% of their body weight compared to 23% for the placebo group. Potential side effects include dizziness, nausea, and constipation.
Phentermine functions like an amphetamine. The compound alters your central nervous system, elevating your heart rate while lowering your appetite. Phentermine is a common weight loss drug for people with diabetes and high cholesterol.
The drug convinces your brain to release more neurotransmitters. These hormones control your metabolism and appetite and “trick” you into exercising more and eating less. Side effects can include dizziness, chest pain, headaches, and trouble breathing.
Belviq gives people the power to control their appetite. The drug influences neurotransmitters’ signals in the brain, so you feel full even after eating a small meal. Belviq is a useful tool to treat obesity for people of all ages and health conditions.
While Belviq can make a significant difference in your waistline, it can’t treat underlying issues. The weight loss formula won’t cure diabetes, high cholesterol, or heart disease. Some of the potential side effects include sore throat, irregular heartbeat, nausea, and seizures.
Xenical is the prescription version of Alli (Orlistat.) Both drugs use Orlistat to prevent the body from absorbing dietary fat up to 30%. The difference is that Xenical is prescription strength.
If you want to get the most out of Xenical, use it while on a diet. Research suggests that the combination can lower body mass up 10%. A study from the Baylor College of Medicine performed a 54-week trial and found that 57% of participants lost more than 5% of their weight compared to 34% in the placebo group.
Take Xenical three times a day before meals. The weight loss prescription eliminates undigested fats within one to two days of consumption. Side effects include soft stools, abdominal pain, and low vitamin D levels.
How Fast Do Diet Pills Work?
You will notice diet pills’ effects almost immediately. For instance, if you try Leanbean, you won’t feel hungry a few minutes after having the pill. The same applies if you take Trimtone–you’ll feel a surge of energy from the coffee beans and green tea.
Instant effects don’t mean instant results. In the best-case scenario, you may lose weight within a week. If you want to see significant weight loss, stick with the pills for several months.
Weight loss takes a long-term commitment and a multi-faceted approach. While pills and supplements can help, they’re not powerful enough to work alone. You also need to maintain a low-fat diet and doctor-approved exercise.
Can You Buy Weight Loss Pills Over The Counter?
You can find over-the-counter weight loss pills, though results will vary. While they can help you lose weight, doctors don’t have substantial research analyzing their long-term benefits and side effects. If you want the best products on the market, you’re better off checking out Instant Knockout, Powher, or one of the other weight loss options on our list.
Most over-the-counter weight management products fall into one of two categories: dietary supplements and non-prescription drugs. The FDA only oversees the non-prescription products, such as Orlistat. Manufacturers must demonstrate to the FDA that a product is safe and effective for long-term human consumption.
Dietary supplement producers have more leeway about claims. While they should make honest statements, the FDA doesn’t review or approve the marketing. If the FDA can prove that a weight loss medication is not safe, it may ask the manufacturer to remove it from shelves.
Do Fat Loss Pills Have Any Side Effects?
Weight loss pills tend to have few side effects. The existing side effects will vary depending on the formula. The FDA doesn’t regulate the claims that supplement manufacturers make, so you should take them with a grain of salt.
Fat blockers, such as Orlistat, may cause gas and irregular bowel movements. A stimulant-type drug may raise your heart rate, high blood pressure, and odds of insomnia. Any supplement that influences your neurotransmitters, including Belviq and Contrave, may cause dizziness, headaches, and nausea.
Everyone has unique health, tolerance, and needs. Side effects will vary from person to person and between over-the-counter products and prescription drugs. If you use a weight loss medication with stimulants, use it for less than three months to avoid long-term side effects.
Final Thoughts – Are Weight Loss Pills Right For You?
If diet and exercise aren’t enough, a weight loss supplement provides a helpful way to achieve your fitness goals. These safe and effective weight loss pills provide the bump you need to shed pesky pounds. Each brand uses a slightly different formula to maximize weight loss, whether you want to reduce your appetite, mitigate absorption, or burn more fat.
While we highly recommend using a good weight loss pill, talk with your doctor about weight loss products first. Doctors can evaluate your health, provide medical advice, and let you know if certain diet pills have side effects. A doctor can also offer you prescription weight-loss drugs, like Alli (Orlistat) and Belviq, instead of over-the-counter varieties.
