How much weight reduction could be achieved by drinking tea along?

Many studies have been conducted in laboratories and on animals with consistent results that tea drinking can assist in reducing body weight and blood cholesterol level. There is however limited information on how much weight reduction could be achieved in human by drinking tea along.

Following are some available indications:

• ‘Physiology & Behavior’ journal: “Effectiveness of green tea on weight reduction in obese Thais: A randomized, controlled trial.” reported 3.3kg weight reduction among obese Thai men over a period of 12 weeks from dinking green tea (compared to those ones who did not).
• Journal of Nutrition: “Oolong tea increases metabolic rate and fat oxidation in men.” The study observed that over 3 days, there was an additional energy expenditure of 281kJ/daily for subjects treated with full-strength tea and a 12% additional fat oxidation.
