It doesn't explain everything, but it actually looks like it's more important than BMI and weight loss

The physical and chemical properties Glutathione molecular weight of 307.33, melting point of 189~193 (decomposition), crystal is colorless transparent thin cylindrical in shape and isoelectric point of 5.93.It is soluble in water, dilute alcohol, liquid ammonia and methyl formamide, and insoluble in alcohol, ether and acetone.Organisms only with physiological activity, GSH and GSSG need to restore to play its important physiological functions.The GSH under high water activity is not easy to save, only controlling the water activity below 0.3 to long-term stability.Studies have found that in vitamin C (pH3.3) in aqueous solution containing GSH, with strong reducing effect of vitamin C, GSH no oxidation of solution for the GSSG, but the decomposition speed is accelerated;But in the vitamin C solution GSSG will not change as GSH, and save the stability is very good.And oral intake of GSSG in the upper small intestine can be restored as GSH, in the small intestine epithelial cell surface by gamma GTP (GSH is decomposed into glutamic acid and Cys-Gly) and the role of the dipeptide enzyme and is absorbed, can also play an important physiological function

This review synthesizes the cellular and physiological mechanisms, contrasts incretin-based therapies with lipid-lowering pharmacotherapy, summarizes the principal randomized trials, evaluates the distinction between plaque regression and plaque stabilization, and outlines unresolved questions and clinical-implementation considerations
One study fed genetically engineered PC mice (Kras G12D /Pdx-1-Cre) with a calorie-restricted diet and observed delays in formation of pancreatic intraepithelial neoplasms (PanIN) [60, 61]
Nanotechnologys application in functional foods and herbal medicines is also becoming an important tool in advancing both precision and personalized medicine as well as nutrition as it allows for treatments and diets to be tailored to individual, environmental, genetic, and lifestyle differences [158]
