The Effect of Green Tea and Aloe Vera Consumption on Weight Loss and Satiety Feeling in Overweight and Obese Women: A Randomized Double-Blind Placebo-Controlled Clinical Trial

BACKGROUND: This study was conducted to determine the effects of tea bags containing green tea and aloe vera on weight loss and satiety feeling among overweight and obese women. METHODS: This randomized double-blind placebo-controlled clinical trial was carried out among 60 overweight and obese women but 56 subjects finished the study. Participants were randomly assigned into 3 groups. Group A received tea bags containing 2 g green tea (n=20), group B received tea bags containing 2 g green tea and 2 g aloe vera (n = 20) and group C (controls) received tea bags containing 2 g black tea, twice with lunch and with dinner daily for 6 weeks. Satiety feeling measured by a VAS (visual analogue scale) questionnaire with 0 to 10 scales. All the participants were on a weight reduction diet (500 kcal less than maintenance) and regular physical activity. RESULTS: Taking tea bags containing green tea for 6 weeks resulted in a significant decrease in weight (-4.3 ± 2.2 kg, p < 0.01), body mass index (BMI; -3.8 ± 1.3 kg/m2, p < 0.05), waist circumference (-6±2 cm, p < 0.01), and body fat percent (-7± 2.5 %, p < 0.01). Subjects who received tea bags containing green tea and aloe vera co-supplements had significantly decreased weight (-3.9 ± 3.0 kg, p < 0.01), body mass index (BMI; -3.5 ± 0.3 kg/m2, p < 0.05), waist circumference (-5±1 cm, p < 0.01), and body fat percent (-5.3± 0.5 %, p < 0.01). In group C we observed statistically decrease in weight (-3.0 ± 1.5 kg, p < 0.05), body mass index (BMI; -3.0 ± 1.0 kg/m2, p < 0.05), waist circumference (-4±1 cm, p < 0.05), and body fat percent (-3± 1.0 %, p < 0.01). There was not any significant difference in satiety feeling before and after intervention in any groups. Meanwhile there were not any significant differences in any variables between groups. CONCLUSIONS: Our study indicated that taking tea bags containing green tea, aloe vera and black tea for 6 weeks more than weight reduction diet among overweight and obese women had beneficial effects on weight, BMI, waist circumference and body fat percentage but had no effect on satiety feeling.
