In the EPIC-PANACEA Study, total meat (red and processed meat and poultry) consumption was positively associated with weight gain in both men and women, in normal weight and overweight subjects, and in smokers and non-smokers alike. This association is thought to be due to the high energy density (i.e., calories) and high fat content found in meat (i.e., animal flesh).
Interestingly, the link between eating meat and weight gain persisted even after controlling for calories. In other words, consuming the same number of calories from a higher meat content diet results in more weight gain than consuming the equivalent number of calories from a lower meat content diet.

PANACEA (Physical Activity, Nutrition, Alcohol, Cessation of of smoking, Eating out of home And obesity) uses data collected from EPIC. PANACEA's general objective is to identify and describe what factors determine weight, weight changes and obesity.
The EPIC (European Prospective Investigation into Cancer and Nutrition) Project was established as a large international collaboration to study the causes of chronic diseases such as cancer, diabetes, obesity, cardiovascular and other diseases of major public importance. It also seeks to investigate the relationship between diet, nutritional status, environmental and lifestyle factors and the incidence of cancer and other chronic diseases. It is the largest study of diet and health ever undertaken, with over 520,000 participants in 10 countries.
