A 'low-calorie diet' involves consuming fewer calories than your body needs to maintain its current weight. This forces the body to burn stored fat for energy, leading to weight loss. While effective for weight loss, very low-calorie diets can be risky and should be supervised by a healthcare professional. Think of it like spending less money than you earn – eventually, you'll use up your savings (stored fat). It's important to ensure you're still getting essential nutrients.
