Whey vs. Pea Protein: Which Makes You Feel Full Longer?
Postprandial plasma amino acid and appetite responses to a low protein breakfast supplemented with whey or pea protein in middle-to-older aged adults

Scientists gave older adults a breakfast with a tiny scoop of either whey or pea protein to see if one made them feel less hungry or boosted muscle-building amino acids more.

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.
When middle-to-older adults eat a low-protein breakfast and add either whey or pea protein powder at 0.13 grams per kilogram of body weight, both types of protein raise levels of essential amino acids in the blood by the same amount over three hours, even though whey has more leucine than pea protein.
In middle-to-older aged adults, adding 0.13 grams of whey or pea protein per kilogram of body weight to a low-protein breakfast results in the same short-term reduction in hunger and increase in fullness over three hours, with no difference in blood levels of ghrelin or GLP-1 or in overall appetite ratings between the two protein types.
In middle-to-older adults, eating a low-protein breakfast with either whey or pea protein at a dose of 0.13 grams per kilogram of body weight results in the same levels of blood glucose and insulin after eating.
When middle-aged and older adults eat a low-protein breakfast with a small added dose of whey or pea protein, plasma levels of most essential amino acids do not change meaningfully, but pea protein raises phenylalanine and asparagine, while whey protein raises aspartic acid.
