Ever wondered why you need Protein to lose weight?

When we talk about about burning calories, we tend to focus on exercise. But our bodies are constantly using energy throughout the day and night. Even when we’re sleeping, we’re still breathing and pumping blood. Our brains are dreaming. We’re still digesting food and finding places to store it. And not all foods are digested equally. 

The components of food—protein, carbohydrates, and fats —require different amounts of energy to digest and process, just as different types and intensities of exercise burn more or fewer calories. Scientists call this metabolic cost the thermic effect of food (TEF). Protein has a much higher TEF than carbs or fat. That is, simply eating more protein means your body is burning more calories during the process of digestion. In some cases, doubling your protein intake will bump up the number of calories you burn throughout the day. That’s one reason why protein, all by itself, helps you lose weight.
