Green Tea Weight Loss: Does Green Tea Help You Lose Weight?

Green tea and weight loss have received much scientific attention in the face of a growing obesity crisis worldwide.

Human, animal and cell studies on green tea and weight loss have been encouraging. Green tea can help you lose weight through several ways:

- Thermogenesis
Green tea stimulates thermogenesis so that energy is converted into heat and not stored as fat. As metabolism and energy expenditure increase, more calories are burned off.

- Burn fat
Green tea is a natural fat burner that increases fat oxidation.

- Reduce absorption of dietary fat
Green tea promotes excretion and prevents absorption of fat.

- Regulate insulin
Insulin is the hormone that controls blood sugar level and reduces cravings. Eating carbs or sugary foods triggers the release of insulin. Excessive insulin can cause fat storage and prevent fat burning. Hence, it is crucial to keep it under control in order to lose body fat.

What are the ingredients in green tea that help lose weight?

EGCG – the powerful catechin polyphenol that is abundant in green tea.

Caffeine – stimulates the nervous system.
Scientists from the Universitary Medicine Berlin found that a combination of EGCG and caffeine in green tea increased fat burning by about 50% compared to 33% with low EGCG only and 34.5% with caffeine only.

Drinking green tea can enhance your weight loss or support weight maintenance when combined with a regular workout regime and proper diet. Even if you don’t need to lose weight, you can still drink green tea for its other health benefits.

Here are some studies and encouraging findings on Green tea and weight loss:

Anti-obesity effects of green tea

“Studies conducted with human subjects report reduced body weight and body fat, as well as increased fat oxidation and thermogenesis and thereby confirm findings in cell culture systems and animal models of obesity.”

Efficacy of a green tea extract rich in catechin polyphenols and caffeine in increasing 24-h energy expenditure and fat oxidation in humans

Green tea has thermogenic properties and promotes fat oxidation beyond that explained by its caffeine content per se. The green tea extract may play a role in the control of body composition via sympathetic activation of thermogenesis, fat oxidation, or both. “

Obesity and thermogenesis related to the consumption of caffeine, ephedrine, capsaicin, and green tea.

“…tea catechins have antiangiogenic properties that may prevent development of overweight and obesity. Furthermore, the sympathetic nervous system is involved in the regulation of lipolysis, and the sympathetic innervation of white adipose tissue may play an important role in the regulation of total body fat in general.”
