Decaf green tea for weight loss
If you want to lose weight, decaffeinated green tea can help. The fat-burning antioxidants in green tea work independently of caffeine, so you don’t need the stimulant to enjoy green tea’s slimming effects. But the process that removes caffeine from green tea leaves also removes more than half its antioxidants. Decaffeinated green tea provides a softer rev to your metabolism than the caffeinated original.
The calorie-burning properties in green tea are called catechins. If you’re reading product labels, you might also see catechins referred to as epigallocatechin gallate, EGCG or flavonoids. The latter could be misleading — all catechins are flavonoids but not all flavonoids are catechins. If you drink green tea purely for its taste — more delicate than the black tea more commonly consumed in the United States and Britain, such technicalities mean little. But if your aim is weight, loss, every catechin counts, according to a report posted by the USDA.
A cup of brewed, loose leaf green tea contains an average of 127mg of catechins, according to a study conducted by the U.S. Department of Agriculture. Brewed decaffeinated tea contains 56mg. Cup per cup, you’d be getting about half as many catechins in brewed decaffeinated tea. You could drink twice as much tea or settle for half of the benefits. If you drink bottled decaffeinated green tea, you would get only 12mg of catechins per serving, according to the USDA. You would need to drink 4.6 cups of bottled tea to obtain the catechins in a single cup of brewed decaffeinated tea or 10 cups to achieve the benefits of brewed caffeinated tea.
Drinking 12 cups of decaffeinated green tea daily — 72 oz. as the USDA measures tea in 6 oz. cups — would burn about as many calories as taking a leisurely 30-minute stroll. You could lose about a pound every four weeks drinking 12 cups of decaffeinated green tea if your results matched those in a clinical study conducted by Kevin Maki, a U.S. researcher who tested the differences between drinking green and black tea for weight loss.
