Some studies suggest that certain cholesterol medications like rimonabant and orlistat can aid in weight loss, while other studies indicate that weight-loss medications generally have modest effects and their long-term safety and effectiveness need further research.

Cholesterol medications are primarily prescribed to manage lipid levels in the blood, reducing the risk of cardiovascular diseases. However, there is growing interest in understanding whether these medications also contribute to weight loss. This article synthesizes findings from various studies to explore the relationship between cholesterol medications and weight loss.
Rimonabant, a selective cannabinoid-1 receptor (CB1) blocker, has been shown to significantly reduce body weight and waist circumference in overweight and obese patients with dyslipidemia. In a study involving 1036 participants, those treated with 20 mg of rimonabant daily experienced a mean weight loss of 6.7 kg over 12 months, compared to the placebo group. This weight reduction was accompanied by improvements in HDL cholesterol and triglyceride levels, suggesting that rimonabant not only aids in weight loss but also enhances lipid profiles.
Orlistat, a gastrointestinal lipase inhibitor, is another medication that has demonstrated efficacy in weight reduction. A systematic review of 28 randomized trials found that orlistat, when combined with a hypocaloric diet, resulted in significant weight loss and improved serum lipid profiles, including reductions in total cholesterol, LDL cholesterol, and triglycerides. Patients using orlistat experienced an average weight loss of around 3 kg, highlighting its potential as a weight management aid in addition to its lipid-lowering effects .
Interestingly, non-pharmacological interventions like electroacupuncture (EA) have also shown promise in reducing weight and improving lipid profiles. A study on obese women found that EA led to a 4.8% reduction in body weight and significant decreases in total cholesterol, triglycerides, and LDL cholesterol levels. This suggests that EA could be a complementary approach to traditional cholesterol medications for weight management.
A comprehensive review of FDA-approved weight-loss medications, including orlistat, lorcaserin, naltrexone-bupropion, phentermine-topiramate, and liraglutide, revealed that these drugs have modest positive effects on cardiometabolic risk profiles. While these medications primarily aim to reduce weight, they also contribute to slight improvements in blood glucose levels, waist circumference, and lipid profiles. However, no single medication was found to improve all cardiometabolic risk factors, indicating the need for personalized treatment plans.
In summary, certain cholesterol medications, particularly rimonabant and orlistat, have been shown to aid in weight loss while improving lipid profiles. Additionally, non-pharmacological interventions like electroacupuncture may offer complementary benefits. While these findings are promising, further research is needed to fully understand the long-term effects and optimal use of these treatments for weight management. For individuals seeking to lose weight while managing cholesterol levels, a combination of medication, lifestyle changes, and possibly alternative therapies may provide the best outcomes.
