For literally decades it was stated that daily energy expenditure/metabolic rate was made of up three components: Resting Metabolic Rate (RMR), the Thermic Effect of Activity (TEA) and the Thermic Effect of Food (TEF). It had long been known humans showed drastically different responses to overfeeding in terms of weight and fat gain. So you might imagine how much of a shock it was when, in 1999, a discovery was made that not only identified a fourth component to metabolic rate but also explained the huge variance in weight gain. That component would come to be called Non-Exercise Activity Thermogenesis or NEAT. Today I want to examine the paper that did both.
Variation in Weight Gain with Overfeeding
As I stated above, it’s long been known that two individuals may gain staggeringly different amounts of weight and fat when they overeat. … Keep Reading
