physiology secrets

1. What is Incretin/Anti incretin Hypothesis-?
Incretin hormones-GIP&GLP-1 are released when we eat. These hormones increases insulin and slow down nutritient absorption and inhibit glucagon secretion.
Antagonistic anti-incretins are released in the small intestine. When there is an incretin/anti-incretin balance, there is sufficient insulin. In type 2 diabetes, the balance is disrupted. Then incretins bind with antiincretins to decrease the insulin efficiency.
2. What are whey proteins?
Liquid material created as a by-product of cheese production called whey contain high core of BCAA-branched chain amino acid.
Benefits-increases protein synthesis,
Increases cellular glutathione-antioxidant,
Consistent whey intake and consistent exercise causes consistent muscle building,
Also aids in weight loss (thro’ gut satiety mechanism, whey protein releases satiety hormones-insulin, CCK, ghrelin)
Side effects-lactose intolerance people may produce allergic reactions.
High doses affects kidney and liver fns, and because of imbalance of minerals in bones –osteoporosis.
