Weight loss refers to the process of reducing body weight, often achieved through a combination of healthy eating, regular physical activity, and lifestyle changes. It involves creating a calorie deficit, where the body burns more calories than it consumes. Effective weight loss strategies focus on sustainable habits, such as eating balanced meals, controlling portion sizes, and engaging in consistent exercise. While some may pursue weight loss for aesthetic reasons, it is often aimed at improving overall health, reducing the risk of chronic diseases, and enhancing physical and mental well-being.
