Résumé
Green tea (Camellia sinensis L.) has an effect on energy metabolism, but little is known about its infusion intake impact on satiety responses. This paper aimed at analyzing the effect of green tea on energy expenditure, satiety response, and food intake in humans. The study involved 21 individuals (11 women, 10 men), and consisted of an open-label, crossover, randomized clinical trial (RBR-928HCW). Evaluation of subjects was performed as an acute study on two different days, after having a standardized breakfast accompanied by water or green tea. Indirect calorimetry was used to evaluate resting energy expenditure (REE), and a visual analogue scale to assess satiety. Food records were used to assess food intake along the day of the trial. Acute ingestion of green tea infusion with the standardized breakfast increased REE (p = 0.014) by 7.2 ± 11.7% at 240min compared to fasting (mean difference of REE between the time of 240min and fasting: +91 ± 157.6 kcal). No significant alterations were observed for substrate oxidation and respiratory quotient compared to the water treatment. A greater feeling of hunger was observed when volunteers ingested green tea (water -828.75 ± 494.2 cm min; green tea -549.8 ± 545.6 cm min; p = 0.026). No significant differences were observed regarding food intake energy and macronutrients between treatments. Green tea increased energy expenditure and the subjective response of hunger in healthy individuals. This study is registered in the ReBEC Platform of the Brazilian Clinical Trials Registry (RBR-928HCW).

BACKGROUND
Green tea (Camellia sinensis L.) has an effect on energy metabolism, but little is known about its infusion intake impact on satiety responses.
OBJECTIVE
This paper aimed at analyzing the effect of green tea on energy expenditure, satiety response, and food intake in humans.
METHODS
The study involved 21 individuals (11 women, 10 men), and consisted of an open-label, crossover, randomized clinical trial (RBR-928HCW). Evaluation of subjects was performed as an acute study on two different days, after having a standardized breakfast accompanied by water or green tea. Indirect calorimetry was used to evaluate resting energy expenditure (REE), and a visual analogue scale to assess satiety. Food records were used to assess food intake along the day of the trial.
RESULTS
Acute ingestion of green tea infusion with the standardized breakfast increased REE (p = 0.014) by 7.2 ± 11.7% at 240min compared to fasting (mean difference of REE between the time of 240min and fasting: +91 ± 157.6 kcal). No significant alterations were observed for substrate oxidation and respiratory quotient compared to the water treatment. A greater feeling of hunger was observed when volunteers ingested green tea (water -828.75 ± 494.2 cm min; green tea -549.8 ± 545.6 cm min; p = 0.026). No significant differences were observed regarding food intake energy and macronutrients between treatments.
CONCLUSIONS
Green tea increased energy expenditure and the subjective response of hunger in healthy individuals. This study is registered in the ReBEC Platform of the Brazilian Clinical Trials Registry (RBR-928HCW).
