The concentration of EGCG—the superpotent nutrient found in green tea—may be as much as 137 times greater in powdered matcha tea. EGCG can simultaneously boost lipolysis (the breakdown of fat) and block adipogenesis (the formation of new fat cells). One study found that men who drank green tea containing 136 milligrams of EGCG—what you'd find in a single 4-gram serving of matcha—lost twice as much weight than a placebo group and four times as much belly fat over the course of three months.
If you’re a Snapple fan, you probably saw “Tea Cleanse” and thought, Great! But bottled teas aren’t necessarily the answer. First, once a tea is made and sits on a supermarket shelf for, oh, an entire NFL season, the nutrients have spent enough time exposed to light and air that they begin to break down. Plus, who knows what else has worked its way into that bottle? Snapple’s All Natural Green Tea packs 120 calories and 30 grams of sugar, while Ssips Green Tea with Honey & Ginseng is sweetened not so much with honey but with high fructose corn syrup.”
Why the discrepancy? The fact is, store-bought teas typically lose 20 percent of EGCG/catechin content during the bottling process, which is why brewing your own is so critical. If you really want bottled tea then shoot for versions with an acid like lemon juice or citric acid, which help stabilize EGCG levels. Recent studies show that the more acidic the environment, the more stable the tea’s nutrients. But even in a highly acidic drink, more than half of the nutrients are gone within 3 months.
The stress hormone cortisol can really screw with your belly. The problem with cortisol is two-fold: First, the chemical makeup of cortisol causes the body to store visceral fat. Visceral fat is stored between your main organs and in the midsection and is the most dangerous type of fat. Experts state that visceral fat increases the risk of diabetes and heart disease.
