Can green tea help you lose weight? Last week a story circulated the UK press about a woman who claimed that drinking nine cups of green tea a day helped her to lose five stone in one year.
Green tea contains bioactive substances in the leaves which dissolve in the water but stay active so that the drinker still gets all the benefits from each cup!
A cup of green tea contains less caffeine (24-40 mg) than a cup of coffee (100-200 mg). Caffeine is a well-known stimulant that has been shown to stimulate fat-burning, but it’s the antioxidants it contains that really help to boost the metabolism. Green tea contains the catechin EGCG (Epigallocatechin gallate), a substance which is known to give a huge boost to the metabolism. EGCG helps to inhibit an enzyme that breaks down the hormone norepinephrine. This hormone is used by the nervous system to tell the fat cells it’s time for them to break down the fat. The more norepinephrine in the system, the stronger the signal sent to those fatty cells and the more fat they break down! Once they’ve been broken down, the fat is released into the bloodstream and becomes energy, leaving you feeling lighter and revitalised!
Green tea has also been repeatedly shown to increase the burning of fat, especially during exercise.
In one study, men who took a green tea extract before exercising burned 17% more fat than men who didn’t get the supplement. This study suggests that green tea can boost the fat-burning effects of exercise.
Another eight-week study showed that green tea increased fat burning, both during exercise and during rest.
So how should you incorporate green tea into your day to get the best benefits?
Drink Before Breakfast/lunch and dinner
Instead of your usual choice of tea or coffee, start the morning with a cup of green tea and you will begin the day with a fat-burning kick start full of antioxidants to boost your immune system. Then substitute your hot drinks throughout the day for a cup of green tea, aiming for 7-9 cups a day! Make sure you drink plenty of water too as apparently, green tea can also work as a diuretic and so could make you dehydrated.
