Leucine Builds Muscle: More Evidence

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

Whey Protein Spares Muscle: More Evidence

Energy restriction is problematic because while it is able to induce weight loss in most people, much of the weight lost is often muscle tissue. The resting metabolic rate is proportional to the amount of skeletal muscle possessed by an … Continue reading

The Bioavailability of HMB

β-hydroxy-β-methylbutyrate (HMB) is a metabolite of the essential and branched chain amino acid L-leucine. Leucine is metabolised to HMB in a two step reaction first to α-ketoisocaproate (KIC) and then to isovaleryl-CoA. This transamination pathway accounts for around 10 % … Continue reading

Protein Synthesis Rates: Should We Eat Protein During The Night?

Proteinaceous tissue, including skeletal muscle, is in a constant state of flux. In this regard skeletal muscle is constantly restructured and the size of the muscle pool within the body is therefore determined by the balance between the catabolic and … Continue reading

How Much Tryptophan Is Converted to Niacin?

There are a number of substances that fall into the grey area between essential and nonessential dietary compounds. Vitamin D is a classic example of this, as in reality vitamin D is a steroid hormone synthesised in the skin through … Continue reading
