In our study, ingestion of commercial green tea capsules
for four weeks was not able to affect body mass, BMI, waist
and hip circumferences, waist/hip ratio measures, or the body
composition (percentages of body fat, body fat weight and
lean mass) of volunteers. While evaluating these parameters,
statistical differences were also not verified in another study
[21], although green tea extracts with higher catechin and
caffeine concentrations were offered to volunteers for a longer
experimental period.
