he demonstrated that respiration is a slow form of combustion (Figure 1). Based on the concept that oxygen burned the carbon in food, Lavoisier showed that the exhaled air contained carbon dioxide, which was formed from the reaction between oxygen (present in the air...
The gut microbiome is emerging as a key modulator of human energy balance. Prior studies in humans lacked the environmental and dietary controls and precision required to quantitatively evaluate the contributions of the gut microbiome. Using a Microbiome
Measurement of Energy Expenditure in Free-Living Humans by Using Doubly Labeled Aater The doubly labeled water method is a form of indirect calorimetry that has been developed only recently to the stage of application to human studies. The m... DA Schoeller - 《Journal of Nutrition》 被引量:...
The increased US food energy supply (adjusted for wastage and assumed to be proportional to energy intake) was apportioned to children and adults and inserted into equations that relate energy intake to body weight derived from doubly labeled water studies. The weight increases predicted from the ...

Food energy is defined as the energy released from carbohydrates, fats, proteins, and other organic compounds. When the three major calorigenic nutrients (carbohydrates, fats, and proteins) in a food are burnt entirely with sufficient amounts of oxygen, it releases energy or food calories that ...
Food and energy security vs. environment The world population is increasing continuously and projected to reach 9.8 billion by 2050 due to the addition of approximately 83 million newborns every year (UN DESA 2017). This rapid and consistent increase in the number of humans is presently a great...
(Table1, Supplementary-Table1). Regional extinctions of large terrestrial mammals (e.g., ground sloths in North and South America) correlate with the arrival of humans15. Humans lived as foragers, fishers, or hunters, but in a few locations began to cultivate domesticated food crops16. Energy...
Recently, an increasing number of studies have characterized the significance of bone as an endocrine organ, suggesting that bone-derived factors regulate local bone metabolism and metabolic functions. In addition, these factors can regulate global energy homeostasis by altering insulin sensitivity, ...
