Bariatric patients often miss protein targets, risking muscle loss
Up to 64% of bariatric patients fail to meet the recommended 60‑100 g of protein daily, which can lead to a loss of as much as 25% of pre‑operative lean mass within the first year. This shortfall contributes to fatigue, poor wound healing and heightened sarcopenia risk.
Dr. Rajan argues that dietary fiber remains undervalued despite robust evidence linking higher intake to lower cardiovascular disease, type‑2 diabetes, and all‑cause mortality. He highlights fiber’s unique journey to the colon, where gut microbes ferment it into short‑chain fatty acids that support barrier integrity and metabolic health. Current consumption patterns lag far behind recommended levels, largely due to ultra‑processed, low‑fiber foods and outdated marketing. Looking forward, innovators like LOAM aim to make fiber more palatable and personalized, positioning it as a cornerstone of next‑generation nutrition.
