Tea and Weight Loss Research
The possibility that green tea helps with weight loss has been a recent
topic in the media. What is the potential role of tea in helping maintain
healthy weight? Unsweetened, fresh-brewed tea, both black and green
has no sodium, no sugar, no fat and virtually no calories, yet tea is
a satisfying, aromatic beverage. This makes tea an ideal choice for
a weight control plan that is part of a healthy lifestyle, especially
when substituting for other sugar sweetened beverages. Another factor
to potentially helping maintain a healthy weight is that regular tea
contains caffeine which has been shown to increase energy expenditure
(number of calories burned). In a study, published in the Journal of
Nutrition, consumption of 3-4 servings of oolong tea was shown to increase
energy expenditure and the rate of fat breakdown. In addition, subjects
drinking tea spent energy at a 3% faster rate and burnt about 70 more
calories a day than those consuming water.
Some emerging research on energy expenditure conducted with tea and tea extracts has suggested that increases in metabolism and rate of fat breakdown may not be solely due to caffeine in the tea. One study measuring the effect of green tea extract on energy expenditure in people showed that drinking either caffeinated water or tea extract significantly increased the number of calories burned, but in addition the rate of fat breakdown was significantly higher for participants drinking tea extract than those drinking the caffeinated water(58). In a second study researchers looked at group of flavonoids in tea and its effect on weight loss and body fat. They found significant weight loss and a significant reduction in total body fat in the people drinking tea flavonoids (equal to 3-4 cups of tea per day) when compared to participants drinking the placebo
While this is active area of research; the preliminary evidence suggests the tea drinking can increase energy expenditure and fat burning. However, there are no conclusive studies that tea drinking has beneficial effects on weight loss. Still, tea is a satisfying, calorie-free beverage that can be substituted for sweetened beverages and is a delicious alternative to plain water in a healthy weight management plan.
*While tea is a naturally rich source of antioxidants, it is not a
substitute for fruits or vegetables which provide a wide range of antioxidants
and essential vitamins and minerals. Please consult your doctor regarding
a diet/nutritional plan that is right for you.
How does green tea work? There are several components
in green tea that seem to work together to provide the health and weight
loss benefits that green tea’s so famous for. Researchers have
pinpointed three components in green tea that seem to have an effect
on weight loss.
Cancer protection.
Cholesterol reduction.
Blood pressure reduction.
Antibacterial and antiviral activity .
Protection against radiation.
Reduction of body fat.
Reduction of blood sugar .
Polyphenols, High Richest in Green Tea Beverage.
It is certain that more studies are needed on how green tea helps with
weight loss. One interesting study on the subject, by the Shizuoka University
in Japan, evaluated all three of these green tea components individually,
as well as in combination, to try and determine just what components
are most important.
This study concluded that the most important component of green tea for weight loss is caffeine. Caffeine is responsible for speeding up the metabolism and creating thermogenesis, which burns fat. However, the study also showed that catechins do seem to have an anti-obesity effect on their own, helping the body to eliminate dietary fat rather than absorbing it.
In short, green tea seems to be the near perfect combination for helping
lose weight and improve health at the same time. Diet and exercise are
still critical to taking off excess weight and keeping it off for good,
but it does appear that green tea can be an effective tool in fighting
the battle of the bulge.
