Slimming teas

But can you really drink your way thin through a cuppa? Natalie Willis, 31, a customer designer from Bristol, has been drinking Dragonfly Organic Pu'er tea for six months and swears by it.

'I wasn't expecting any miracles from a simple tea, but I noticed the effects within a month after drinking it ceremoniously three-times-a-day with just a normal, balanced diet and the odd naughty treat,' she explains.

'I lost 10lbs in a month and went from a size 16 to a 14. Five months down the line, I'm very content with my curvy size 12 frame, and although I know that my new healthy living lifestyle has contributed to my weight loss greatly, I have no doubt that Pu'er has been instrumental in my successful long-standing fight against the flab.'

Still, Natalie's experience wasn't part of a clinical trial. I've been drinking a variety of these so-called slimming teas and coffees several times a day for a fortnight, and other than enjoy their lovely flavours, I have not dropped a dress size (or even an ounce).

Commenting on the teas alone, celebrity nutritionist Jeanette Jackson (www.jeannettejackson.com) thinks we shouldn't rely on these drinks as 'miracle' weight-loss methods, although she stresses that they are certainly beneficial to health.

'I would never suggest the tea is used as a slimming aid. They purport to aid weight loss, which has never been scientifically proven.

'The weight loss aspect probably comes from the fact that milk and sugar are not added to the drink and also, when people buy these teas, they may be at a stage where they are making other changes to diet as well, so weight loss is a consequence of a change of routine.

'However, many of these teas can offer tremendous health benefits and have been known to reduce cholesterol and aid digestion. They also contain high amounts of antioxidants and so are healthy from that perspective. The teas can, and do, offer health benefits and so could be included in a daily diet, but to lose weight and keep it off, you need a healthy diet.'

And, of course, you need a healthy relationship with food, which drinking a tea can never teach you. Surinder Phull, head nutritionist at Eat Well adds: 'Effective weight loss is a complex issue which involves dealing with both physical and emotional factors.

'In certain cases, a particular food may be useful as part of a whole weight management programme, but the magic bullet for weight loss simply does not exist in the form of any food, drink or quick-fix diet.'

Weight loss for many people is hard work, she says, which involves tackling individual issues that may be preventing someone from losing weight and looking at the reasons why someone may be over-eating.

'Although a particular food may help boost the metabolism of certain individuals, it certainly will not work alone,' she concludes.
