Fructose metabolism is known to deplete hepatic ATP stores due to unregulated phosphorolation. In previous studies rate of ATP replenishment following fructose infusion as measured using 31P Magnetic Resonance Spectroscopy has been inversely correlated with steatosis in non alcoholic fatty liver disease (NAFLD) and with BMI. In this pilot study we show ATP depletion and recovery following oral fructose intake (equivalent sugar content ~2 cans of coke). Results are more consistent across subjects when fructose is ingested with glucose (1:1 ratio) due to decreased variation in intestinal absorption rates
