    Thermogenic ingredients and body weight regulation: a review of clinical evidence

    Hursel R, Westerterp-Plantenga MS

    Published in International Journal of Obesity

    Methodology

    Review of randomized human trials of thermogenic ingredients (catechins, caffeine, capsaicin, protein) on energy expenditure, satiety and weight maintenance.

    Key Findings

    Thermogenic ingredients produced increases in 24-hour energy expenditure of a few percent, with effects that attenuate over time and vary with habitual caffeine intake.

    Conclusions

    Thermogenic supplements give small, short-lived increases in metabolism rather than sustained metabolic elevation.

    Limitations

    Heterogeneous doses and populations; long-term adherence data limited.

    Supplements Studied

    Thermogenic ingredients produced increases in 24-hour energy expenditure of a few percent

    Outcomes Measured

    Thermogenic ingredients produced increases in 24-hour energy expenditure of a few percent, with effects that attenuate over time
