Weight Loss Pill Benefits: What Does Science Say?

Plenty of studies prove that weight loss pills work for weight loss. We’ll review some of that evidence below.

Caffeine is one of the most popular and proven ways to lose weight. There’s a reason it’s found in so many weight loss supplements. In this study, researchers gave caffeine to a group of 76 obese adults. Researchers observed significant drops in fat mass, waist circumference, and overall weight in the high caffeine intake group.

Fiber is another popular weight loss pill ingredient. You can find plenty of glucomannan supplements, for example, that absorb water in the gut and help you lose weight. In this 2005 study, researchers gave a glucomannan supplement to a group of 176 people and found it helped them lose weight. Other studies have found that up to 95% of American adults do not get their recommended daily fiber intake. Fiber is not just linked to weight loss: it’s also linked to good heart health and other benefits.

Garcinia cambogia extract has been popular for a decade. The small, pumpkin-like fruit contains an active ingredient called hydroxycitric acid (HCA) linked to weight loss. Studies show that HCA may inhibit fat formation, suppress appetite, and boost metabolism. However, there are few large-scale studies in humans verifying the weight loss benefits of garcinia cambogia extract, and we need more research to verify all of these effects.

Many weight loss pills contain green tea extract, including two proven fat-burning ingredients: caffeine and EGCG. We’ve already talked about caffeine. However, EGCG is an antioxidant-like compound that appears to increase the rate of fat burning in the body. Green tea is also well-tolerated by most healthy adults. The L-theanine in green tea could nullify some of the unpleasant side effects of caffeine, including jitters and anxiety.

Conjugated linoleic acid (CLA) has surged in popularity in recent years. It’s a type of fatty acid that appears to be linked to weight loss. If you believe in the power of the keto diet, then CLA supplements may be your new best friend. Although some studies have linked CLA to powerful weight loss results, other studies have been less conclusive. Nevertheless, many people take 3g to 6g of CLA daily to lose weight.

Some of the best weight loss pills are only available via prescription. Qsymia, for example, is one of the most popular weight loss pills available today. The FDA approved Qsymia for weight loss because of impressive clinical trials. In phase I and phase II clinical trials, researchers found that Qsymia led to an average of 10% body weight loss. Qsymia contains a combination of phentermine and topiramate, helping your body lose weight in multiple ways. Physicians may prescribe Qsymia and other weight loss pills to people with a BMI over 30 or those with a BMI over 27 and a related health condition (like type 2 diabetes or high blood pressure).

You may not need a fancy herbal or plant extract to lose weight. Sometimes, all you need is a common mineral like calcium. Some studies have shown that calcium can increase lipolysis (fat burning) while decreasing fat accumulation and absorption.

Some weight loss pills contain capsaicin, the active ingredient in chili peppers that gives them their spiciness. Studies show that capsaicin and other capsaicinoids increase lipid oxidation (fat burning), energy expenditure, and overall weight loss.

Probiotic supplements could help you lose weight. One of the most popular weight loss pills available today, BioFit, only contains probiotics. Probiotics are beneficial bacteria that reside in your digestive tract, helping you break down foods, absorb nutrients, and maintain good immunity. Because of growing research supporting the weight loss benefits of probiotics, some researchers have suggested it’s time to use probiotics to prevent or treat obesity.

Other popular science-backed weight loss pill ingredients include forskolin, chromium, fucoxanthin, raspberry ketones, Yohimbe, and African mango, all of which have some scientific evidence proving they can help with weight loss.

Overall, studies show that taking a good weight loss pill could accelerate weight loss results. By taking the right weight loss supplement daily, you can enjoy powerful fat burning and appetite suppressing benefits, making it easier to maintain a caloric deficit and lose weight.
