CALERIE

CALERIE (Comprehensive Assessment of Long-term Effects of Reducing Intake of Energy) is a significant clinical trial initiated in the United States to scrutinize the impacts of extended calorie restriction on healthy human subjects.

Background

The concept of calorie restriction (reducing daily calorie intake without malnutrition) has garnered interest in the scientific community for its potential longevity and health benefits. Numerous animal studies have indicated that calorie restriction can lead to increased lifespan and reduced incidence of various diseases, notably cardiovascular disease and cancer.

Objectives

The primary objectives of the CALERIE study are:

• To determine if prolonged caloric restriction has similar health benefits in humans as seen in animal models.
• To ascertain whether caloric restriction can decrease the incidence of cardiovascular diseases and cancer.
• To examine the potential for calorie restriction to extend human lifespan.

Study Locations

The CALERIE study is being conducted across multiple research institutions in the U.S., including:

• Pennington Biomedical Research Center, Baton Rouge, Louisiana
• Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University, Boston, Massachusetts
• Washington University School of Medicine, St. Louis, Missouri.

Study Population

CALERIE has opted to study individuals who are not obese. The reason behind this decision is that calorie restriction in obese populations is already known to increase life expectancy. However, it's crucial to determine if these effects are strictly due to weight loss or if they stem from the intrinsic benefits of calorie restriction itself.

Relation to the Calorie Restriction Society

The Calorie Restriction Society is an organization that promotes and practices prolonged caloric restriction for its purported health benefits. Members of this society advocate for the potential longevity and health advantages of calorie restriction based on existing animal studies. The CALERIE trial aims to provide empirical evidence in humans, thereby offering insights that could validate the claims of the society.

Potential Implications

Should the CALERIE study demonstrate substantial benefits of calorie restriction in non-obese humans, it could revolutionize dietary guidelines and recommendations for healthy living. The implications could span across preventive medicine, nutritional science, and public health recommendations.

Conclusion

The CALERIE study stands as a monumental step in understanding the potential health benefits of caloric restriction in humans. With its rigorous scientific approach and its collaboration across multiple esteemed institutions, CALERIE aims to provide definitive answers on a topic that has intrigued scientists for decades.
