Protein intake and obesity in young adolescents

The abundance of protein and its functional diversity in living systems makes it essential for virtually all life processes. Dietary protein and amino acid requirements are affected by age, body size, body composition, physiological state, and the level of energy output. The requirement for dietary protein is based on the indispensable amino acids under all conditions and under specific physiological and pathological conditions as well as the synthesis of dispensable amino acids and other nitrogen-containing compounds. Previous findings have shown the influence of early intake of proteins on the development of overweight in healthy children. The present review focused on the possible association (if any) between protein intake and later development of obesity. The aim is to benefit physicians, dieticians as well as parents to understand future consequences of incorrect dietary habits in young adolescents and encourage healthy dietary habits to avoid obesity.
