Hibiscus and Lemon Verbena May Help Increase Feelings of Fullness
Hibiscus and lemon verbena contain significant amounts of polyphenols, which have antioxidant properties. A recent study has found that hibiscus and lemon verbena extracts may help suppress appetite and increase feelings of fullness.
Thirty-three overweight adults participated in the study. They consumed 500 mg of hibiscus and lemon verbena extracts or a placebo daily for 60 days. They switched interventions after a 30-day washout period.
Appetite sensations (the desire for food) were evaluated at the end of each 60-day period. Participants reported their feelings of hunger, satiety, and fullness after consuming a buffet style meal. Lipid profiles and hunger-related hormones were measured at baseline and at the end of each 60-day period.
Participants experienced a decrease in appetite sensation when taking the hibiscus and lemon verbena supplement. They also reported feeling fuller after eating compared to the placebo group, even though they reduced their calorie intake.
In addition, participants had improved lipid profiles following supplementation. They also saw a decrease in the hormone ghrelin, which increases appetite, and in increase in GLP-1, which helps bring on feelings of fullness.
The study was conducted by researchers from San Antonio Catholic University of Murcia. It was published online ahead of print on September 20, 2021 in the European Journal of Nutrition.
A previous study found that fiber from corn starch may also help increase feelings of fullness.
