Green tea, originally from China, is a type of tea that is made from Camellia sinensis leaves.
Unlike other leaves used for black tea – green tea leaves have not withered, which is why they still have their lush green colour.
Health effects of the drink are touted amongst nutritionists and health experts.
Looking at scientific studies it does seem that a number make a strong link between drinking the herbal tea and weight loss.
A green tea weight loss trial found that green tea had a big effect on weight loss of the patients in the study.
Moderately overweight people where given two drinks each a day.
For one group all were placebos, the other had one serving of green tea while the other had two.
Scientists who carried out the research, in Shanghai, China, found: “We observed a decrease in estimated intra-abdominal fat in the GT3 group,” or the group with two servings of green tea.
They added: “In addition, we found decreases of 1.9 cm in waist circumference and 1.2 kg body weight.”
This is fairly impressive considering the study did not include any other changes in diet or exercise.
A similar study that aimed to measure the effects of green tea on overweight Thai patients found the same thing.
“We conclude that green tea can reduce body weight in obese Thai subjects by increasing energy expenditure and fat oxidation,” the Department of Physiology, Faculty of Medicine, at Khon Kaen University found.
The University of Maryland Medical Centre’s Complementary and Alternative Medicine Guide strongly recommends green tea for those looking to boost weight loss.
The paper states: “Clinical studies suggest that green tea extract may boost metabolism and help burn fat.
“One study found that the combination of green tea and caffeine improved weight loss and maintenance in people who were overweight and moderately obese.”
This facility specifically recommends 2 to 3 cups of green tea per day, depending on the brand – or 100 to 750 mg per day of standardised green tea extract.
However, not all studies are in agreement. Others have found no correlation between drinking green tea and weight loss.
Although drinking green tea or taking green tea supplements decreases cholesterol, the Chinese Academy of Medical Sciences and Peking Union Medical College found, and some studies have observed drinking the tea can reduce the risk of death from cardiovascular disease.
So while a certain link cannot be made between green tea and weight loss, it does seem that the relatively cheap drink is likely to have a positive effect on your overall health.
Have you heard of the latest diet that nutritionists claim to offer ‘superior’ weight loss.
The diet involves limiting carbs to 50 grams or less, which puts the body into a state of ketosis.
