In the battle against obesity, many individuals turn to various methods and medications to aid in their weight loss journey. One such medication that has gained popularity is Orlistat. But does Orlistat actually burn existing fat? In this comprehensive article, we will delve into the scientific evidence and explore the mechanism of action, recommended use, and potential benefits of Orlistat in the treatment of obesity.
Orlistat, also known by its brand name Xenical, is a non-centrally acting anti-obesity agent that works locally in the gastrointestinal tract to inhibit pancreatic and gastric lipases. These enzymes play a vital role in the digestion of long-chain triglycerides. By inhibiting these enzymes, Orlistat prevents the absorption of dietary fat, leading to a reduction in calorie intake and potential weight loss. (1)
Mode of Action
Orlistat is a synthetic derivative of lipstatin, a naturally occurring lipase inhibitor produced by Streptomyces toxytricini. When Orlistat is consumed, it forms a covalent bond with the active serine residue site of gastric and pancreatic lipases, rendering them inactive. As a result, the hydrolysis of dietary fat into absorbable free fatty acids and monoglycerides is hindered. (2)
The Efficacy of Orlistat
Numerous studies have examined the efficacy of Orlistat in promoting weight loss. In randomized controlled trials, Orlistat has been shown to be significantly more effective than a placebo in reducing body weight. The weight loss achieved with Orlistat is modest but clinically significant, with studies indicating an average weight loss of approximately 2.7 kg (5.95 lbs) more than diet alone.
Additionally, Orlistat has demonstrated efficacy in improving cardiovascular risk profiles. Modest weight loss of 5% to 10% in obese individuals has been associated with improvements in cardiovascular risk factors and a reduced incidence of type 2 diabetes. Studies have shown that Orlistat not only aids in weight loss but also improves glycaemic parameters in obese adults with type 2 diabetes mellitus. (3)
Recommendations for Use
In adults, the recommended dose of Orlistat is one 120 mg capsule with each main meal. It is advised to take the capsules immediately before, during, or up to 1 hour after the meal. To maximize the efficacy of Orlistat, it is important to follow a well-balanced, mildly hypocaloric diet that contains approximately 30% of calories from fat. Distributing the daily intake of fat, carbohydrate, and protein evenly over three main meals is recommended.
It is worth noting that gastrointestinal side effects, such as oily stools and increased frequency of bowel movements, may occur when Orlistat is consumed with a high-fat meal. Therefore, it is advisable to reduce fat intake while using Orlistat to minimize these side effects. (4)
Safety and Tolerability
Orlistat is generally well tolerated by adults and adolescents. Adverse effects experienced by individuals taking Orlistat are typically mild and transient, with most resolving within a few weeks of treatment. The most common adverse events are related to the gastrointestinal tract, including oily spotting, flatus with discharge, and fecal urgency.
It is important to note that Orlistat may interact with certain medications. The absorption of ciclosporin and amiodarone may be affected when coadministered with Orlistat. In addition, the bioavailability of oral contraceptives may be reduced in women who experience severe diarrhea while taking Orlistat. (5)
The Role of Orlistat in Obesity-related Comorbidities
Obesity is often associated with various comorbid conditions, such as type 2 diabetes mellitus and the metabolic syndrome. The use of Orlistat in the management of these conditions has shown promising results. Studies have demonstrated that Orlistat improves glycaemic parameters in obese adults with type 2 diabetes, leading to a reduction in the need for antidiabetic medication or an improvement in glucose tolerance.
Furthermore, Orlistat has been shown to be effective in reducing cardiovascular risk factors, irrespective of diabetic status or the presence of metabolic syndrome. It has the potential to improve factors involved in the pathogenesis of cardiovascular disease, contributing to overall cardiovascular health.
Orlistat and Weight Maintenance
Weight maintenance is a crucial aspect of any weight management strategy. Orlistat has shown efficacy in maintaining weight loss in both short-term and long-term studies. In a four-year double-blind, randomized, placebo-controlled trial, Orlistat was found to significantly reduce weight regain compared to placebo. Additionally, a study focusing on weight maintenance after weight loss with a very low-energy diet demonstrated significantly reduced weight regain with Orlistat.
It is important to note that attrition rates in clinical practice may be higher than those observed in clinical trials. Factors such as cost and side effects may contribute to the discontinuation of Orlistat treatment. However, it is worth mentioning that several pharmacoeconomic studies have shown that Orlistat is a cost-effective treatment for obese patients with or without type 2 diabetes.
Orlistat and Adolescents
While most of the available literature focuses on adults, there have been some studies evaluating the impact of Orlistat on weight loss in adolescents. A multi-center trial involving obese adolescents showed that Orlistat led to a decrease in BMI compared to placebo. However, another study found that Orlistat did not significantly reduce BMI in adolescents after six months of treatment. Further research is needed to determine the efficacy and safety of Orlistat in this population.

B4: The Perfect Pre-Workout Weight Loss Supplement
Next up, we have B4 by BPI Sports. This unique weight loss support supplement combines the benefits of a pre-workout formula with the power of weight loss ingredients, all thanks to its star ingredient, dendrobium. Let’s explore what sets B4 apart from the competition.
Dendrobium: The DMAA Alternative
One of the key ingredients in B4 BPI Sports is dendrobium. Used in Chinese medicine for years, dendrobium is believed to be a suitable substitute for DMAA in pre-workout and weight loss supplements. While the exact mechanisms are still being studied, dendrobium is thought to enhance energy levels and improve physical performance.
Quercetin: Fuel Your Workouts
B4 also includes quercetin, a powerful antioxidant with anti-inflammatory properties. Research suggests that quercetin may support harder training and combat metabolic fatigue, allowing you to push through your workouts and reach new levels of performance (3). By including quercetin in its formula, B4 aims to provide the fuel you need to maximize your training sessions.
Yohimbine: Unlock Greater Fat Loss
Yohimbine, another key ingredient in B4, has been shown to support greater fat loss by blocking alpha-2 adrenergic receptors in fat cells (1). By inhibiting these receptors, yohimbine may promote the breakdown of stored fat and enhance weight loss efforts. Combined with the other ingredients in B4, yohimbine aims to help you achieve your fat loss goals.
In conclusion, Orlistat is a medication that inhibits the absorption of dietary fat, leading to modest weight loss when used in conjunction with a well-balanced diet. It has demonstrated efficacy in promoting weight loss, improving cardiovascular risk profiles, and managing obesity-related comorbidities such as type 2 diabetes. Orlistat is generally well tolerated, with mild gastrointestinal side effects being the most commonly reported adverse events.
While Orlistat can be an effective tool in the management of obesity, it is important to remember that weight loss should be approached holistically, incorporating healthy eating habits, regular physical activity, and behavioral changes. If you are considering the use of Orlistat, it is advisable to consult with a healthcare professional to determine if it is suitable for your individual needs and to ensure proper monitoring of its effects.
