What was done
The authors conducted a narrative review of existing literature examining diet-induced thermogenesis (DIT), focusing on its determinants including food palatability, macronutrient composition, circadian rhythm, sleep, age, physical activity, obesity, and diabetes mellitus.
What was found
The abstract reports that DIT accounts for approximately 10% of total energy expenditure. No other specific quantitative findings or statistical effect sizes are reported, and the authors note substantial contradictions across existing studies.
Why it matters
DIT represents a potentially modifiable component of daily energy expenditure, suggesting that manipulating dietary or behavioral factors might theoretically assist weight management strategies in obesity.
Limits
This is an unsystematic narrative review providing no quantitative synthesis. The abstract highlights that primary studies in this field are limited by small sample sizes, significant methodological heterogeneity, and contradictory results.
