Visceral adipose tissue (VAT) is associated with chronic metabolic and inflammatory disorders. Normal weight, overweight, and obese people can all be overfat with visceral adipose tissue (VAT). In this case series, we describe the total body composition of three male patients with excess VAT after undergoing prolonged medically supervised water-only fasting followed by an exclusively whole-plant-food diet free of added salt, oil, and sugar. All patients lost a substantially higher percentage of VAT mass than total fat mass. These clinical observations warrant further observation into the efficacy of fasting and diet to reduce VAT.
