Acute effects of breakfasts containing α-lactalbumin, or gelatin with or without added tryptophan, on hunger, ‘satiety’ hormones and amino acid profiles

Proteins are the most satiating macronutrients. Tryptophan (TRP) may contribute to the satiating effect, as it serves as a precursor for the anorexigenic neurotransmitter serotonin. To address the role of TRP in the satiating properties of dietary protein, we compared three different breakfasts, …
