Hibiscus sabdariffa tea affects diet-induced thermogenesis and subjective satiety responses in healthy men but not in women: a randomized crossover trial

The aim of this study was to investigate the effect of Hibiscus sabdariffa tea on energy expenditure, satiety response and food intake. This is an open-label, crossover, randomized clinical trial that comprised 21 subjects (11 women, 10 men). The individuals were evaluated at acute moments (fasting and after eating standardized breakfast accompanied by water or H. sabdariffa tea). Resting energy expenditure was measured by indirect calorimetry, subjective satiety responses were evaluated with a visual analogue scale and food intake was assessed by using food records. The volunteers who drank the H. sabdariffa tea had lower perception of hunger (p = 0.002) and greater feeling of satiety (p = 0.01) and fullness (p = 0.009) compared to control. Men who ingested the H. sabdariffa tea had an increase in nitrogen energy expenditure (water: 1501 ± 290.7 kcal, H. sabdariffa tea: 1619 ± 288.9 kcal; p = 0.029). In comparison to control, men presented less perception of hunger (p = 0.003) and desire to eat (p = 0.016), increased satiety (p = 0.021) and fullness (p = 0.01), and women oxidized more fat (p = 0.034) when they drank H. sabdariffa tea. There was no difference between treatments regarding the energy and macronutrient intake from the first meal and throughout the day (p > 0.05) for all participants. The H. sabdariffa tea only affected energy expenditure and satiety responses in men. Clinical trial registry: ReBEC Platform of the Brazilian Clinical Trials Registry (https://ensaiosclinicos.gov.br/) - RBR-5HZ86T. Novelty: H. sabdariffa tea promoted an increase in energy expenditure and caused less perception of hunger/desire to eat in men. H. sabdariffa tea intake increased postprandial fat oxidation in women.
