High protein intake stimulates postprandial release of gut hormones PYY and GLP-1, but when meals are matched for volume, calories, and appearance, this hormonal increase does not reduce subsequent ad libitum food intake.
Eating a high-protein meal will spike your satiety hormones (GLP-1 and PYY) more than high-fat or high-carb meals of the same size and calories. However, this hormonal spike does not guarantee you will eat less at your next meal. If you match the volume and calories of your meals, you will likely consume the same amount of energy regardless of the protein content.
We conclude that a high protein meal increases circulating concentrations of the gut hormones PYY and GLP-1, but when meals are matched for volume, appearance and caloric value, these gut hormone changes do not translate into a reduction in ad libitum food intake.
Why this rating
Randomized crossover design with strict controls for volume, calories, and appearance in healthy volunteers.
