Effect of weight loss teas. Teas work?

Hi. I wish I could say they do, but alas, they don’t and the results of weight loss are meagre at best. I feel that losing weight is a real challenge and requires exercise with healthy controlled diet and there is no scientific evidence of such teas working. These teas are usually marketed as herbal teas and the ‘herbal’ tag makes it sound as if it is completely safe. You must realise that these teas contain ingredients not mentioned on the packets and could possibly affect you by interfering with any drug you may be taking. Ill try and explain why these teas don’t work. • If you have ever consumed certain types of teas,you may have noticed that you are spending more time in the bathrooms. This is because they contain natural laxatives and diuretics. This is not very effective in reducing weight because the laxative action occurs after the food has already been absorbed by your body. So the calories are already being taken and hence you won't see a major weight loss. Also an excessive use will cause dehydration (throwing out a lot of salts and water), which is not so good for your body. • Some teas claim to increase your metabolism and thus reduce weight. This action is only transient and occurs in short burst and adds no significant influence on your net daily calorie burn value. • Some others may contain substances that claim to decrease appetite. These usually work by releasing a substance in your brain that makes you feel full thus reducing your appetite. But over a long run this is harmful as it interferes with the normal functioning of your brain and also may interfere with any medication that you may be taking. Also if you have noticed, certain weight loss teas suggest working out and following a certain diet which raises the doubt of the effectiveness of weight loss being attributed to the tea instead of the exercise and diet. It is safe to say that if you are trying to lose weight, the most effective, clinically proven method is regular exercise with a healthy balanced diet. There is no evidence of the effectiveness of weight loss teas.
