The Benefits of Protein

Protein is an essential macronutrient that your body needs an adequate supply of to perform a variety of important tasks, including making enzymes, hormones, and body chemicals. Protein is also a major component of bones, muscles, cartilage, skin, and blood. Listed below are benefits of protein that affect blood sugar, weight, muscle, and bone health.

Blood sugar management – Because protein is digested slowly, it can help prevent a rise in blood sugar when eaten with carbohydrates. This effect may be more likely to occur when overall carbohydrate intake is slightly decreased and overall protein intake is slightly increased to reach a protein to carbohydrate to fat ratio of 30:40:30 vs. 15:55:30 (1).

Satiety – Protein can help you feel full and satisfied quicker and for longer than carbohydrates and fat because it is more slowly digested (2).

Weight loss – Because protein increases satiety, your body’s hunger signal remains suppressed between meals for longer, leading to less snacking and overall consumption of food (2).

Muscle building – If you’re trying to build muscle with strength training, protein is essential for repairing muscle and promoting growth. You may need to increase your protein intake due to the increased catabolism of muscle experienced during strength training (3).

Bone health – Diets high in protein promote bone growth by stimulating an anabolic hormone, insulin-like growth factor I. In addition, some protein sources contain are a good source of calcium and phosphorus which help to prevent calcium losses in bone (4).
