Do green tea and grape extract help burn fat?
Combined epigallocatechin-3-gallate and resveratrol supplementation for 12 wk increases mitochondrial capacity and fat oxidation, but not insulin sensitivity, in obese humans: a randomized controlled trial.

People took a daily pill with green tea and grape extract for 12 weeks. Their muscle cells got better at making energy from fat, and their bodies used more fat after meals, but their weight and insulin response didn't change.
Surprising Findings
Fat oxidation didn’t increase—but it declined in the placebo group.
Most expect supplements to boost fat burning; here, the placebo group’s fat oxidation dropped over time, making the supplement look protective rather than enhancing.
Practical Takeaways
If you're overweight and want to improve how your muscles handle fat, EGCG+RES may help at the cellular level.

Taking this specific combination of green tea and grape-derived supplements for 12 weeks helps the muscle cells in overweight and obese people make more energy, like upgrading their internal batteries.
After taking this supplement combo for 12 weeks, overweight and obese people burn more fat and less sugar for energy, even after eating a fatty meal.
Even though this supplement helps muscles burn more fat and make more energy, it doesn’t help the body use insulin better to control blood sugar in overweight or obese people.
After eating a fatty meal, people who took this supplement had lower levels of fat in their blood than those who took a placebo, suggesting it helps the body clear fat from the bloodstream faster.
Taking this supplement for 12 weeks doesn’t make people lose body fat or burn more calories at rest — even though it changes how their muscles use fuel.
