Whether your aim is to lose excess body weight or not, adequate protein is essential to your health. As a vital part of nutrition, protein is second only to water in the body's physical composition, makes up 20% of total body weight, and is the primary component of muscle, connective tissue (collagen), skin, hair, nails and integral organs including the heart and brain. It is also required in the formation of enzymes, hormones, transport molecules like haemaglobin, and antibodies. Numerous individual amino acids are are also known to act as neurotransmitters.
It also helps with reduced weight regain, which is a common obstacle to ong term weight maintenance. A randomised, parallel study in 148 moderately obese men and women, showed that a higher protein intake, that is 18% versus 15% of energy during weight maintenance after weight loss, resulted in a 50% lower body weight regain. |
