Losing weight with green tea? A green tea fat burner?
You might be getting more and more confused about the different ingredients in weight loss supplements.
It’s not so strange though that they now picked green tea (extract) as the main fat burner ingredient. Why?
Besides only carrying 4 calories per serving, green tea contains many ingredients that help in your fight to lose weight.
Catechins (the most important one being EGCG) : powerful antioxidants to protect your body against the free radicals in your body that destroy healthy cells. These catechins have several weight loss advantages, namely:
1. Speeding up your metabolism.
Catechins speed up your metabolism through thermogenesis – converting calories into heat – which in turn helps you body to burn fat and helps you to lose weight!
2. Regulating your digestive system.
What’s more, the green tea antioxidants regulate your digestive system, making you feel full faster and digest your food better.
So, on the one hand you’ll eat less and on the other hand, whatever you DO eat will be digested better.
3. Regulating your glucose production.
Research suggests that green tea catechins may regulate your glucose by slowing the blood sugar level down after a meal.
Green tea possesses anti-diabetic activity, similar to insulin, as EGCG, the main green tea fat burner, and other catechins slow down the digestive enzymes responsible for breaking down carbohydrates.
This in turn decreases glucose production in the gastrointestinal system resulting in lower levels of glucose and insulin.
4. Reducing body fat and waist circumference.
Research performed by Dulloo (1999) shows that catechins reduce the waist circumference by 4.5% and body weight by 4.6%.
A 2005 study performed among Japanese men confirms this by suggesting the daily consumption of 690 mg green tea catechins for 12 weeks reduces body fat as well as body weight, BMI, waist circumference, and body fat mass!
Green Tea Fat Burner vs Other Fat Burners
Green tea extract is safer than other substances often found in weight loss supplements.
Most often contain lots of laxatives which will make you lose weight but will also dehydrate you and give you short term results.
As soon as you would stop taking these chemical fat burners, you are most likely to gain weight again, if not more than when you started dieting!
A high quality green tea fat burner, however, contains real green tea extract and has no side effects.
Only when used in excess green tea side effects may develop.
Side effects of Green Tea Fat Burner
Some people using green tea fat burner have reported getting headaches, feeling dizzy, jittery, or dehydrated. These symptoms are related to the caffeine found in green tea. Read more about green tea side effects here.

Also, it’s important to drink enough water to prevent dehydration and to consult your doctor before buying green tea fat burners.
Do not use green tea during pregnancy or when lactating: green tea and pregnancy.
