Protein from lean sources like beef, poultry, fish, dairy, or soy are weight loss rock stars. The amino acids that make up protein cause your body to release the fat-burning and energy-stabilizing hormone glucagon. The process of digesting protein also stimulates your body to release the satiety hormone CCK. This one-two punch combined with the fact that it takes your body more energy to digest and breakdown protein compared to carbohydrates or fat makes it a must-have at every meal throughout your day.
Where to get it: The possibilities are endless, but lean proteins like Greek yogurt, cottage cheese, and organic grilled chicken strips are especially convenient.
