Several obesity experts have claimed the growth in food supply after 1965 was the primary cause of the global obesity pandemic based on ecologic data. Using public access global data we explored per capita food supply and two metabolic diseases i.e., obesity and raised fasting glucose. We also compared overweight military service members who were semi-randomly assigned to countries with variable food supply and observed obesity outcomes for 7 years. Among countries with 2008 food supply above the United States in 1965 2,926 kcal per capita per day, higher national supply was paradoxically associated with lower prevalence of raised fasting glucose e.g., r -0.42, p 0.001.
