Ginger infusion increases diet-induced thermogenesis in healthy individuals: A randomized crossover trial

The purpose of this study is to evaluate the acute effect of ingesting ginger infusion on energy metabolism, appetite responses, and food intake in healthy individuals. This is a clinical (RBR-9ZJGQM), randomized, open, and crossover study with a minimum interval of seven days between treatments. Two drinks, ginger infusion (2 g) and water (control) were served with a standard breakfast. It has 21 volunteers of both sexes (18-40 years old, 18.5-26 kg/m2). Consumption of ginger tea increased on average 95.5 +/- 27.4 kcal/day the non-nitrogen energy expenditure after 240 min of ingestion (p = 0.002). There was a significant effect of ginger on diet-induced thermogenesis (difference between ginger tea treatment vs. control: 113.0 +/- 43.0 kcal/day, p = 0.016). How-ever, appetitive responses and prospective food intake did not differ between ginger tea and water intake.

Automated summary

This study evaluated the acute effects of ingesting ginger infusion on energy metabolism, appetite responses, and food intake in healthy individuals. The results showed that consuming ginger tea increased non-nitrogen energy expenditure and diet-induced thermogenesis, but had no effect on appetite responses and prospective food intake.
