A 38-year-old marketing executive came to me last month, annual health report in hand, genuinely puzzled. Everything read "normal," he said, so why was he wiped out by four in the afternoon and slowly growing a paunch he'd never had? His glucose was fine. His cholesterol sat "within range." And yet his body was already three or four years into a metabolic problem no one had bothered to name. This is the quiet failure of the standard Indian check-up.
