Exploring the potential of green tea for reducing weight: What's the evidence?
In recent studies, green tea has emerged as a potential ally in the fight against weight gain for women with obesity or overweight. The National Center for Complementary and Integrative Health (NCCIH) recommends that drinking 2-3 cups of green tea per day can provide enough active compounds to aid weight loss, with some experts suggesting up to 5 cups daily may be beneficial without causing adverse effects.
The key active components in green tea are catechins, particularly Epigallocatechin gallate (EGCG). A daily intake of 300-1000 mg of catechins (with a dose of EGCG typically around 300mg) has shown modest body weight reductions, particularly when combined with exercise.
Consuming green tea or its extract with meals can help prevent side effects like stomach irritation and may promote greater fat oxidation by shifting energy utilization away from carbohydrates towards fats. The caffeine and catechins in green tea boost fat metabolism and reduce fat absorption, but the effectiveness may vary depending on individual metabolism, baseline caffeine consumption, and diet composition.
The NCCIH advises that people should consult a healthcare professional about the most suitable dose of green tea, as it may interact with certain medications, such as beta-blockers like nadolol (Corgard). In rare cases, green tea can cause liver problems, especially when consumed in pill form.
It's important to note that the benefits of green tea for weight loss are likely to be very small, and its effects may be lower than those of other weight loss methods, such as exercise and portion management. A balanced diet, regular exercise, and a healthy lifestyle are still essential for achieving and maintaining a healthy weight.
Other tips for weight loss include making a specific plan with realistic goals, exercising regularly, getting plenty of sleep, managing stress, aiming for slow, steady weight loss, eating a balanced diet with all necessary nutrients, keeping a food diary, and seeking support from friends, family, or support groups.
More high-quality, long-term studies are necessary to confirm the benefits of green tea for inflammatory diseases, mental health, and neurodegeneration. However, the research so far suggests that green tea's properties may offer additional health benefits, such as a lower risk of cardiovascular disease and certain cancers.
In conclusion, for overweight or obese women, drinking 3 to 5 cups of brewed green tea daily or taking equivalent green tea extract doses around 300-1000 mg catechins (EGCG), ideally consumed with meals and combined with physical activity, represents the most evidence-supported approach for modest but meaningful weight loss benefits while minimizing side effects. Moderation is key to avoid issues like nervousness, insomnia, or stomach upset due to caffeine.
