Tea and weight loss

Several studies have correlated green tea with increased metabolism and thus weight loss. Indeed, these studies showed that the administration of tea has resulted in an additional increase of 3% in the energy consumed by the body, namely the burning of 67 additional calories per day compared to those who consumed an equivalent solution of caffeine or plain water. These experiments showed it’s the substances, such as methylxanthines which cause the additional increase in metabolism.

However, this increase is transient and the body quickly adapts, which means that there will be no significant long term effect. Tea can be very nutritious, but to lose weight you simply need to consume fewer calories than you burn.

Tea is an excellent source of antioxidants and flavonoids that may benefit your cardiovascular system. Flavonoids inhibit the action of free radicals and thus reduce the amount of cholesterol oxidized and deposited in the vessels.

Black or green tea?

Until recently, green tea was considered more beneficial than black. The reason has to do with a very important antioxidant called epigallocatechin gallate (EGCg).

However, recent studies have shown that black tea is richer in two other substances (theaflavins and thearubigens) that are associated with various beneficial effects on the human body. Thus both types are now considered beneficial to human health. A large survey of 3,000 adults showed that the frequent consumption of black tea reduces the risk of cardiovascular events by 50% and may also reduce the levels of bad (LDL) cholesterol.

Green tea is also particularly beneficial for health. Scientific studies indicate that green tea may help in preventing cancer and cardiovascular diseases. To date, there have been more than 30 scientific studies investigating the effect of drinking green tea. Most of these demonstrated that green tea may help protect against certain cancers, such as those affecting the colon, stomach, esophagus, gall bladder and pancreas.
