What is the effect of Green tea (Camellia sinensis) and green tea extract on weight loss. Personally, I wouldn’t rely on it. In my opinion, there is no short cut to weight loss other than by eating lower calorie fiber rich plant-based whole food.
I would say, drink the tea, not use the extract. It’s more enjoyable to drink hot tea rather than take a pill, etc.
‘It has been suggested that green tea and its components might reduce body weight by increasing energy expenditure and fat oxidation, reducing lipogenesis, and decreasing fat absorption [1 ods.od.nih.gov/factsheets/WeightLoss-HealthProfessional/#h2]’.
Yes, there seems to be evidence one can lose weight drinking green tea or by using an extract thereof.
‘Increases energy expenditure and fat oxidation, reduces lipogenesis and fat absorption Several clinical trials of good methodological quality on green tea catechins with and without caffeine
Research findings: Possible modest effect on body weight. No safety concerns reported for use as a beverage, contains caffeine; some safety concerns reported for green tea extract
Reported adverse effects (for green tea extract): Constipation, abdominal discomfort, nausea, increased blood pressure, and liver damage [2 ods.od.nih.gov/factsheets/WeightLoss-HealthProfessional/#h2]’.
I drink Japanese green tea and also smoothies made from it. You might want to read some other articles I have written about green tea and its possible health benefits. I drink it every day. Try reading this one, here.

Plant based whole food has all the right nutrients in the correct amounts. Nature knows best, not man. Rely on nature to provide you with everything your body needs to thrive and stay alive the longest. Give your body what it was designed to eat. Real food.
