Thermic effect of food accounts for approximately what percentage of our daily energy expenditure?

Question

BlackTom AI · Accepted Answer

The prompt asks about the thermic effect of food (TEF) and its share of daily energy expenditure, but no answer options are provided to compare choices. 
First, consider what TEF represents: it is the energy required for digestion, absorption, metabolism, and storage of nutrients after a meal, and it typically constitutes a modest portion of total energy expenditure. 
Commonly cited ranges show TEF accounting for roughly 5% to 15% of daily energy expenditure, with a frequently cited approximate value around 10%. This reflects the metabolic cost of processing fed nutrients compared with basal energy use and physical activity. 
If we imagine possible alternative percentages, some would fall below this range (e.g., 5% or 6%), which would underestimate TEF, while others might exceed it (e.g., 15% or 20%), which would overestimate TEF for most individuals under typical conditions. 
The provided answer, 10%, aligns with the conventional mid-range estimate commonly used in nutrition textbooks and discussions of energy balance, acknowledging that individual variation exists due to factors like meal composition, body composition, and metabolic rate. 
However, without the actual list of options to evaluate, we cannot formally eliminate or confirm other choices in this question beyond noting the typical TEF range and the conventional midpoint of 10% as a reasonable estimate. 
In summary, TEF generally represents about 10% of daily energy expenditure, with plausible variation, but the lack of explicit options prevents a comparison-based justification for each option here.
