There is just one problem. The only data available is types of food, they have no idea whether the obese people ate any meat. Or any sugar. If just the availability of meat makes people obese, they have overturned everything science knows about cellular respiration.

"In the analysis of obesity prevalence across 170 countries, we have found that sugar availability in a nation explains 50% of obesity variation while meat availability another 50%. After correcting for differences in nations' wealth (Gross Domestic Product), calorie consumption, levels of urbanization and of physical inactivity, which are all major contributors to obesity, sugar availability remained an important factor, contributing independently 13%, while meat contributed another 13% to obesity," says Professor Maciej Henneberg, head of the Biological Anthropology and Comparative Anatomy Research Unit. "While we believe it's important that the public should be alert to the over-consumption of sugar and some fats in their diets, based on our findings we believe meat protein in the human diet is also making a significant contribution to obesity," Professor Henneberg says.

The research has been conducted by PhD student Wenpeng You, who recently presented the findings of his work at the 18th International Conference on Nutrition and Food Sciences in Zurich, Switzerland. This research has also formed the basis of two papers on the issue, published in BMC Nutrition and the Journal of Nutrition&Food Sciences.

"There is a dogma that fats and carbohydrates, especially fats, are the major factors contributing to obesity," Mr You says.


Mr You says there have been several other academic papers showing that meat consumption is related to obesity, but the authors have often argued that it's the fat content in meat that contributes to the problem. "On the contrary, we believe the protein in meat is directly contributing to obesity," Mr You says.

Professor Henneberg says: "It would be irresponsible to interpret these findings as meaning that it's okay to keep eating a diet high in fats and carbohydrates. Clearly, that is not okay, and this is a serious issue for our modern diet and human health.
