Meal replacement refers to products designed to substitute a regular meal, providing essential nutrients in a convenient form. These products often come in the form of shakes, bars, or powders and are formulated to deliver a balanced mix of proteins, carbohydrates, fats, vitamins, and minerals. They are commonly used for weight management, convenience, or when individuals are unable to prepare a full meal. Many people use meal replacements as part of a diet plan or busy lifestyle. They can be beneficial for those looking to control calorie intake or maintain nutritional balance. However, it's important to choose high-quality products and consult with a healthcare professional if considering long-term use.
