Posted on January 10, 2019 by Robert Barrington

The mainstream solution to weight gain is a forced calories restriction diet and aerobic exercise. These are often used in combination in order to elicit a ‘negative energy balance’ which is assumed will cause weight loss. Often weight loss does … Continue reading →

Higher Protein Intakes Can Benefit the Elderly

Posted on August 8, 2018 by Robert Barrington

Individuals with more skeletal muscle tend to be healthier than those with less. Skeletal muscle mass is directly proportional to resting metabolic rate and so those with more lean mass will have higher metabolic rates and are therefore usually leaner. … Continue reading →

Leucine Builds Muscle: More Evidence

Posted on October 6, 2017 by Robert Barrington

High protein diets are beneficial to weight loss. The exact reason for this is not clear but may relate to the availability of protein to build skeletal muscle. As skeletal muscle tissue increases in mass, body composition improves because the … Continue reading →

Skeletal Muscle Growth: Prioritise The Essential Amino Acid

Posted on August 17, 2017 by Robert Barrington

Skeletal muscle is stimulated to grow during the periods of recovery following exercise, most usually resistance training. However, for this to happen stimulation from the diet in the form of protein is required. In particular, it is known that certain … Continue reading →
