Does Green Tea Actually Boost Metabolism? Here's What the Research Says
Green tea has been hyped for decades. The research is more nuanced — and more interesting — than either the believers or skeptics admit.
The short answer: yes, modestly
Multiple meta-analyses confirm a small but real thermogenic effect from EGCG (the active catechin in green tea), particularly when paired with caffeine. We're talking a 3-4% bump in daily calorie burn — not a miracle, but not nothing.
Why dose matters
A single cup of green tea provides roughly 50-100mg of EGCG. The doses used in clinical research are typically 300-500mg. To get the studied benefit, you'd need to drink 4-6 cups a day — or take a concentrated extract.
The real value
Green tea is most effective as one tool among several. Stack it with movement, protein, and other thermogenic botanicals, and the effects compound.
