Consumption of High Leucine-Containing Protein Bars after Breakfast Affects Amino Acidemia and Subjective Appetite in Older Adults
Consumption of our bar formulation increases blood leucine availability and net exposure to EAA to the same extent as consumption of a high protein diet. High protein at breakfast results in greater net exposure to EAA and leucine, which may support muscle protein synthesis in the elderly.

Commentary
This study investigated a diet to optimize protein and leucine intake to stimulate muscle protein synthesis in older adults. To do this, they were investigating amino acidemia and appetite responses in elderly people after consuming breakfast, a high carbohydrate, substandard amount of protein and leucine frequent meal.
The study involved five men and three women who ate a protein- and leucine-rich bar preparation two hours after consuming a low-protein or high-protein meal, and blood samples were taken for six hours to analyze amino acid, insulin and glucose levels. Hunger and satiety were also assessed by VAS.
The sample is too small, so please see this page for reference only.
