Leucine seems to play a role in regulating the “nitrogen balance”. This altered during aging, causing an imbalance between production and degradation of muscle proteins. It caused the loss of muscle mass is observed in the elderly.

The optimal consumption of leucine reduces 16% of the calories in a meal, reduce by 80% the need to snack between meals and a 50% increase in intake of energy available. These data are given by various researches in the world including the Harvard School of Public Health.

According to researchers at the University of Illinois, leucine stimulates the metabolism to burn excess fat from deep tissue and replace muscle tissue, particularly in the abdominal region.

What seems to emerge from all this research is that a sufficient supply of leucine, transformed in part by excess fatty tissue and muscle will burn another part in the metabolic process.
