    UnlabelledFood components with thermogenic properties are promising antiobesity agents. Ginger (Zingiber officinale Rosc.) bioactive compounds have a capsaicin-like vanillyl portion, which has been attributed to thermogenic effect in previous experimental studies. However, studies conducted in humans have evaluated only the acute thermogenic effect of ginger, and demonstrated contradictory results. We evaluated the effect of long-term consumption of dry ginger extract on the resting energy expenditure (REE) of female adults with high body adiposity.MethodsThis is a secondary analysis of a randomized, double-blind, placebo-controlled clinical trial (NCT02570633). Participants age 18 to 60 y were randomly assigned into two groups: Intervention (600 mg of ginger extract daily) and placebo (cellulose). The intervention lasted 3 mo. Anthropometric measurements, blood pressure, and REE were assessed at each visit.ResultsA total of 66 female participants with high body adiposity were included in the analysis (mean age: 29 y [range, 20-55 y]; body mass index: 23.3 ± 2.7), with 30 participants in the ginger group and 36 in the placebo group. There were no significant differences in baseline characteristics between the groups. No differences were observed for group × time interaction on REE. Body composition and blood pressure followed the same pattern (all P > 0.05).ConclusionsGinger extract consumption for 3 mo did not change the REE, anthropometric, and clinical data of female adults with excess adiposity.Copyright © 2022 Elsevier Inc.
