I simplify the science of macronutrients and vitamins to help you make informed daily food choices. ## Photos and videos - ![Understanding macronutrients is fundamental to nutrition.

Your body does not just need fewer calories. It needs a precise balance of macronutrients, like protein for tissue repair and specific carbohydrates for brain function. When you grasp how these nutrients impact your metabolism, you stop guessing and start seeing consistent, sustainable health results. Nutrition is often overcomplicated by fad trends, but the underlying biology is consistent. My approach focuses on practical application of nutritional science based on your specific life stage and body composition. ### Why Macronutrients Matter Protein is the building block for your body. For example, nursing mothers require an additional 20 grams of protein daily to maintain milk supply, while older adults should aim for 1 to 1.5 grams of protein per kilogram of body weight to maintain muscle mass. Carbohydrates are not your enemy. They are the primary fuel source for your brain and daily activities. Fats are essential for hormone function and protecting your cardiovascular health. When you know how to balance these, you can enjoy regular foods like rotis and vegetables while hitting your health targets. ### Food as Information Every food you consume sends a signal to your body. Leafy greens, salmon, and nuts are not just calories; they contain the vitamins and minerals that dictate everything from your skin glow to your energy levels. I use body analysis data—measuring your fat percentage, visceral fat, and muscle mass—to move beyond the scale. This allows us to adjust your plan based on how your body is actually responding to the fuel you provide. Whether you are managing thyroid issues, anemia, or post-pregnancy recovery, my protocols ensure you get the right nutrients to support your recovery and growth without resorting to starvation. ## About Surbhi Aggarwal I am Surbhi Aggarwal, based in Punjabi Bagh.
