CCK is not well known publicly but well understood by scientists, endocrinologists, dieticians, and pharmacists. For example, pharmaceutical companies pay attention to this hormone by investigating its use for weight loss solutions, creating medications targeting CCK. Multiple studies I reviewed related to CCK are still inconclusive. Nevertheless, based on hypotheses and informed discussions of researchers in papers, there appear to be two viable ways to increase cholecystokinin secretion. The options to increase CCK are consuming adequate protein and healthy fat in our diet.
