Dr. Richa Pareek on Instagram: "Black coffee- no sugar, no milk ☕ From a medical point of view, it’s one of the cleanest ways to drink coffee. It has almost zero calories, doesn’t cause blood sugar spikes, and helps improve alertness and concentration. The caffeine can also support metabolism and fat oxidation, while the antioxidants in coffee are linked to better heart and liver health. Simple, effective, and evidence-based. #BlackCoffee #Caffeine #CoffeeConsumption #CalorieFree #GlycemicContro
