Isoleucine: Difference between revisions

Isoleucine, like other branched-chain amino acids, is associated with insulin resistance: higher levels of isoleucine are observed in the blood of diabetic mice, rats, and humans.{{pmid|25287287}} In diet-induced obese and insulin resistant mice, a diet with decreased levels of isoleucine (with or without the other branched-chain amino acids) results in reduced adiposity and improved insulin sensitivity.{{pmid|29266268}}{{pmid|33887198}} Reduced dietary levels of isoleucine are required for the beneficial metabolic effects of a [[wikipedia:Low-protein_diet|low protein diet]]. In humans, a protein restricted diet lowers blood levels of isoleucine and decreases fasting blood glucose levels.{{pmid|27346343}} Mice fed a low isoleucine diet are leaner, live longer, and are less frail.{{pmid|37939658}} In humans, higher dietary levels of isoleucine are associated with greater [[wikipedia:Body_mass_index|body mass index]].
