Obesity is a significant risk factor for cardiovascular diseases (CVDs), but recent research offers hope for those looking to reduce these risks naturally. A study led by Reza Mahdavi and colleagues explored how combining Nigella sativa (black cumin seed oil) with a low-calorie diet can help reduce cardiometabolic risk factors in obese women.
What Was the Study About?
With cardiovascular diseases being a leading cause of death worldwide, particularly among those who are obese, finding effective strategies to manage weight and improve metabolic health is critical. This study set out to determine whether adding black cumin seed oil to a low-calorie diet could make a meaningful difference in reducing the risk factors associated with heart disease.
In this double-blind, randomized controlled trial, 90 obese women aged 25-50 years were recruited. Each participant had a body mass index (BMI) between 30 and 35 kg/m². They were randomly assigned to receive either a low-calorie diet combined with 3 grams of Nigella sativa oil per day (1 gram before each meal) or a placebo for 8 weeks. The researchers measured various health indicators, such as weight, waist circumference, and biochemical parameters, at both the beginning and end of the trial.
Key Findings
- Significant Weight Loss: Women in the Nigella sativa group experienced a more substantial weight reduction (-6.0%) compared to the placebo group (-3.6%), highlighting the potential of black cumin seed oil in supporting weight loss efforts.
- Reduced Waist Circumference: The study also found that waist circumference decreased significantly more in the Nigella sativa group (-6.9%) compared to the placebo group (-3.4%). This is particularly important as excess abdominal fat is closely linked to increased cardiometabolic risks.
- Improved Lipid Profiles: The Nigella sativa group showed a significant decline in triglyceride levels (-14.0%) and very low-density lipoprotein (VLDL) levels (-14.0%) compared to the placebo group, which saw much smaller changes (1.4% and 7%, respectively). Lower triglyceride and VLDL levels are crucial for reducing the risk of heart disease.
Why Does This Matter?
This study provides compelling evidence that Nigella sativa oil, when combined with a low-calorie diet, can significantly reduce key cardiometabolic risk factors in obese women. By helping to reduce weight, trim waistlines, and improve lipid profiles, black cumin seed oil offers a natural and effective complement to traditional weight loss strategies.
For those seeking to lower their risk of cardiovascular diseases, incorporating Nigella sativa oil into a well-balanced, low-calorie diet could be a powerful tool. As always, it’s important to consult with a healthcare provider before starting any new supplement regimen, but this study suggests that black cumin seed oil may offer substantial benefits for heart health, particularly in individuals at higher risk due to obesity.
