The metabolic syndrome is a grouping of pathological
conditions related to obesity and insulin resistance. We found
that EGCG significantly decreased blood glucose, insulin, and
insulin resistance in high-fat–fed mice. Furthermore, short-term
treatment with EGCG reversed the effects of a high-fat diet on
blood glucose. A previous study showed that EGCG (10 g
TEAVIGO/kg diet) reduced plasma insulin in high-fat–fed
C57BL/6J mice (19).
