Whey and weight loss

Whey, the serum or liquid part of milk remaining after separation of the curd, results from the coagulation of milk by acid or proteolytic enzymes. Whey proteins have a relevant nutritional value, and several commercial uses have been developed by the dairy industry.Whey is a satietogenic food. Yes as other proteins but is whey a better satietogenic food than muscle protein either from animals or seafood?
It is not clear ( http://www.jacn.org/content/26/6/704S.full.pdf+html ) ( http://www.sciencedirect.com/science/article/pii/S0031938407003782 ) but (http://www.sciencedirect.com/science/article/pii/S003193840800005X) some authors are in keeping with this assertion (Hall WL, Millward DJ, Long SJ, Morgan LM. Casein and whey exert
different effects on plasma amino acid profiles, gastrointestinal hormone
secretion and appetite. Br J Nutr 2003;89(2):239–48).
So whey should be a major component of weight loss program.
interestingly a peptide from casein collected in the whey fraction during cheese making by acidification of milk is a potent factor of satiety.
