Brief Summary

Introduction: The influence of tea or coffee supplementation on body weight in adolescents has never been tested. The aim of the present study was to investigate the effect of tea and coffee consumption on body weight and body fat in an obese adolescent population. Methods: Randomized clinical trial, parallel group study comparing 3 weight loss interventions comprised of a similar dietary recommendation with either coffee (coffee group), tea (tea group) or placebo (herbal tea). Sociodemographic data and medical history details were retrieved from medical files. The body mass index Z (BMI Z) score and fat percentage as measured by bioelectrical impedance were compared between groups at 3 and 6 months.

Study Arms (3)

Coffee

EXPERIMENTAL

The coffee group was instructed to consume 2 cups of coffee a day, the amount that was previously described as beneficial in epidemiological studies and safe for children and adolescence. Each cup of coffee contains 250 ml of coffee, which contains approximately 80 mg of caffeine. The children were allowed to add milk to the coffee and sweeten it with artificial sweetener

Dietary Supplement: Coffee

Green Tea

EXPERIMENTAL

The green tea group will be instructed to drink 3 cups (230CC) of Chinese green tea (Wissotzky Tea Israel Ltd). Each tea bag contains 500 g of fine dried herb parts. Each cup contains 84 mg total catechin and 32 mg caffeine. The participants were instructed to leave the tea bag for 2 minutes before drinking.

Dietary Supplement: Green tea

Herbal tea

PLACEBO COMPARATOR

The control group consumed 3 cups a day of Wissotzky- kid drink (Wissotzky Tea Israel Ltd), which is a drink that is marketed for children containing an infusion of fruits and plants. Each tea bag contains 2.7 gr plants parts with no evidence of polyphenols or caffeine.

Dietary Supplement: Herbal tea (placebo)
