In a surprising revelation, a Harvard-educated physician has shared how something as simple as drinking cold water could help accelerate fat burning. According to the expert, when you consume cold water, your body must expend energy to heat the water to your internal temperature — a process that naturally boosts your metabolism. This thermogenic effect, while modest, contributes to increased calorie burn throughout the day. Combined with a balanced diet and regular exercise, this simple habit can support weight management goals. The doctor emphasizes that while cold water isn't a magic solution, it’s a science-backed habit that can complement a healthy lifestyle.
