Green tea or green coffee (GC)? Green tea extract (GTE) is the current winner in the battle of the bulge! For one, #GTE has a higher caffeine component, and when it comes to ingredients that can have a significant impact on supporting your metabolism and help you burn more fat, #caffeine is king. Second, the research on GTE far exceeds that of #GC, making it a little more convincing that including GTE as part of your diet may potentially be beneficial to fat loss.
