Can a tiny protein bar trick your body into feeling full like a big breakfast?
Consumption of High-Leucine-Containing Protein Bar Following Breakfast Impacts Aminoacidemia and Subjective Appetite in Older Persons

Older people often eat little protein at breakfast. This study gave them a small bar with extra leucine two hours later to see if it could make them feel as full as if they’d eaten a big protein breakfast.

When total protein intake is low, meals with added leucine lead to a greater decrease in feelings of hunger than meals with different amino acid profiles.
In adults aged 74 on average, a protein bar with 16 grams of protein and 1.5 grams of added leucine produces the same essential amino acid exposure in the bloodstream as a meal with 32 grams of protein, because the added leucine increases the efficiency of amino acid absorption.
In adults aged 74 ± 7 years, a protein bar with 16 grams of milk proteins and 1.5 grams of free leucine consumed two hours after a low-protein breakfast raises plasma leucine to about 590 µM and maintains essential amino acid levels at the same level as a 32-gram high-protein breakfast.
In adults around 74 years old, eating a leucine-enriched protein bar after a low-protein breakfast reduces hunger for six hours as much as eating a 32-gram high-protein meal and more than eating a 13-gram low-protein meal.
In adults around 74 years old, eating a specific protein bar with 1.5 grams of leucine and 16 grams of milk protein causes plasma leucine levels to rise to about 590 micromoles per liter, which is higher than the peak level after a 32-gram high-protein breakfast and matches levels linked to increased muscle protein synthesis.
