Absolutely! Nutrition and lifestyle choices have a profound impact on brain health. Alongside antioxidants, omega-3 fatty acids, and regular exercise, maintaining a healthy weight plays an important role in supporting cognitive function. Using a BMI calculator can help you understand whether your weight is within a healthy range, which is linked to better circulation, lower risk of metabolic diseases, and improved memory performance. Combined with quality sleep, stress management, and social engagement, monitoring your BMI can be part of a holistic approach to protect your brain, enhance focus, and promote long-term mental clarity.
