Contemporary research results have portrayed tea as 'a functional food product for the management of weight' (Clinical Reviews in Food Science and Nutrition 2002).
According to a recent report from the Australian Bureau of Statistics, two-thirds of adult Australians are overweight or obese and many young children are heading in the same direction. Overweight becomes an issue of both image and health in general and the sufferers are seeking solutions from all sources.
It has been reasonably established that tea is effective in reducing body fat composition by various mechanisms, though generally speaking in two main areas: increasing body fat consumption and reducing fat formation.
Teas can be divided into two main families: conventional tea made of 'Camellia Sinensis' leaves (from green tea to black tea); and herbal teas made from all parts of other plants. Most of the contemporary researches have gone into studying teas made of 'Camellia Sinensis' (green tea, white tea, Oolong tea and black tea etc), although other herbals such as lotus leaf and Gynostemma have also been analysed in the area of obesity treatment.
To combat weight problems, we see many consumers taking up tea drinking. Some achieve much better results than others. Here are a few challenges, but these may be helpful in achieving a lasting result.
Firstly, tea is a beverage, not a medicine. It regulates body fat deposit and oxidisation through its regular consumption. Its effect is moderate, but lasting. The Chinese say 'you cannot drink a cup of hot tea in a hurry', the same principle applies to trying to lose weight though drinking tea. One's body metabolism rate is a balancing act. There are many rapid weight loss programmes currently on the market claiming to produce weight loss almost immediately. Most of them force the body energy consumption expenditure out of balance in such a forceful way that, as soon as the programme is finished, the balance not only bounces right back but is also likely to overshoot, like stretching an elastic band or spring. People often gain back more weight than they lost.
Secondly, tea consumption should be part of a weight management package, but not the single solution. For example, we encourage people to gradually replace their sugar rich beverage with tea; drinking tea without sugar or milk to maximise the benefits in both weight reduction and other aspects; snack healthily, and use all opportunities to remain active. Relying on tea alone but retaining an unhealthy life style is bound to lead to disappointment in terms of weight loss.
Finally, stop worrying about which tea is the most powerful one for weight loss. There are six main categories of Chinese teas, all with weight-reducing effects. There are also herbal blends combining various herbs and teas with different weight-reducing mechanisms to make the recipe more effective than a single tea alone. My advice to people is always to find the tea(s) you enjoy drinking and make it part of your life style. The health benefits of long term tea consumption, including weight reduction, are far greater than using a 'most powerful' tea for just a couple of weeks.
