Obese people are contributing to the world food crisis and climate change, experts say.
The London School of Hygiene and Tropical Medicine calculated the obese consume 18% more calories than average.
They are also responsible for using more fuel, which has an environmental impact and drives up food prices as transport and agriculture both use oil.
The result is that the poor struggle to afford food and greenhouse gas emissions rise, the Lancet reported.
It comes as the World Health Organization predicts the obese population will double by 2015 to 700m.

The Myth of Cholesterol - the Bad and the Good
Written by Gloria Tsang, RD
Our body does need cholesterol to make bile salts, hormones and vitamin D. It is mainly produced by our liver. Cholesterol will build up on the artery walls when the level of cholesterol in the blood is too high. There are 2 main types of blood cholesterol: LDL (the "Bad" cholesterol) and HDL (the "Good" cholesterol).
High amounts of the bad LDL will deposit cholesterol on the artery walls forming plaques. More and more plaques will narrow the arteries lumen and may eventually block blood flow. Therefore LDL is considered the "Bad" cholesterol. Saturated fats and trans fatty acids are the most important factors that raise blood cholesterol, not dietary cholesterol! Monounsaturated fats and polyunsaturated fats found in nuts and fish for instance, can lower the LDL level. In addition, soluble fiber found in fruits, oats, barley and legumes can also lower LDL.
The good HDL, on the other hand, takes excess cholesterol away and carries it back to the liver to be excreted. It can also remove some of the cholesterol already attached to the artery walls. Therefore HDL is considered the "Good" cholesterol as high levels of HDL in the blood can decrease the risk of heart disease. Physical activity can also raise HDL level.
