Fat people cause global warming

The Lancet has released a report on the link between obesity, health, and transport policies. This effectively says that fat people are a global warming risk.

Urban transport policies that promote walking and cycling would reduce food prices by reducing the global demand for oil, and promotion of a normal distribution of BMI would reduce the global demand for, and thus the price of, food. Decreased car use would reduce greenhouse gas emissions and thus the need for biofuels, and increased physical activity levels, would reduce injury risk and air pollution, improving population health.
