The effect of basal insulin on global and regional brain glucose uptake and metabolism in humans was studied using 18-fluorodeoxyglucose and positron emission tomography (FDG-PET). Eight healthy male volunteers aged 49.3 +/- 5.1 years were studied twice in random order. On each occasion, they received an infusion of 0.1 mg. kg(-1). min(-1) somatostatin to suppress endogenous insulin production....

total fast of approximately 150 days! This impressive energy reserve is due both to the high energy content of triglycerides versus polysaccharides, and the fact that triglycerides are stored in essentially anhydrous Harvard Medical School form; polysaccharides such as glycogen are hydrated Boston, Massachusetts 02115 in storage form, decreasing their efficiency as fuel. † Beth Israel Deaconess...
