Protein is more than just a building block for muscles. It plays a vital role in weight loss by boosting metabolism and helping to control hunger. When you eat protein, your body burns more calories digesting and metabolizing it compared to fats or carbohydrates. This is known as the thermic effect of food (TEF), which increases your overall calorie burn.
Protein also promotes satiety, meaning it helps you feel full longer. This can reduce your overall calorie intake, making it easier to stick to a calorie deficit for weight loss. Simply put, protein helps you eat less without feeling deprived.
How Protein Helps Maintain Muscle Mass During Weight Loss
Losing weight isn’t just about shedding fat – it’s also about preserving muscle. During weight loss, your body tends to burn fat and muscle for energy. Consuming enough protein helps mitigate muscle loss, preserving lean muscle mass while you burn fat.
This is important because muscle burns more calories than fat, even when you’re resting. So, keeping your muscles intact helps you maintain a higher metabolism.
