Why is creating a calorie deficit important for a fat burn diet?

Creating a calorie deficit is important for a fat burn diet because it allows your body to tap into stored fat as a source of energy. When you consume fewer calories than your body needs to maintain its current weight, it starts using stored fat for fuel. This leads to a gradual and sustainable loss of body fat over time. However, it's important to create a moderate calorie deficit to ensure you're still getting enough nutrients and energy for your daily activities and exercise.
