Researchers at Duke University Medical Center and St. Luke’s and Roosevelt Hospital Center, Columbia University, found that obese people with Type 2 diabetes undergoing GBP surgery have much lower levels of circulating branched-chain amino acids and the aromatic amino acids phenylalanine and tyrosine, compared with obese patients with diabetes who lost an equal amount of weight by following a diet.
“The most intriguing finding from the current study is that amino acids, particularly the branched-chain amino acids, decreased more significantly after gastric bypass surgery than after the same weight loss through a diet intervention,” said lead author Blandine Laferrère, MD.
