Round 1: Weight Loss

Green Tea vs. Oolong Tea

Both oolong and green tea come from the same plant, Camellia sinesis. The major difference, aside from taste, is the length of time it takes to process and ferment the tea. Green tea is the least processed, while oolong tea takes a little bit longer, although not quite as long as black tea.

The processing time of green tea gives it the weight loss edge over oolong tea. The fermentation process breaks down polyphenols in tea, which are a great source of antioxidants for the body. Because green tea has been fermented the least, it retains more polyphenols than oolong tea and gives you a greater weight loss edge.

Studies have found green tea very successful for weight loss, however in amounts too high to believe any person will ever consume that much. However more studies confirm successful weight loss through drinking green tea than oolong tea.

WINNER: Green Tea


Round 2: Side Effects Green Tea vs. Oolong Tea

Oolong and green tea both contain caffeine, so you should expect similar symptoms to arise if you drink too much of either. Too much caffeine can cause dehydration, muscle cramping, and headaches, regardless of tea type.

The amount of caffeine in each tea varies by how it is prepared as well as the method by which its consumed. Because green tea has been on the market longer you can get your green tea fix through pills, lotions, air diffusers, candles and soaps. Oolong tea is unfortunately still only available in water plus leaf combination.

Since oolong tea is processed longer and more polyphenols are destroyed, oolong has slightly more caffeine than green tea and more likely to cause caffeine-related side effects.

WINNER: Green Tea

Tea Round 3: Taste

Green Tea vs. Oolong

Okay so when it comes to weight loss, taste is usually one of the first things to hit the road and the sad truth is that it’s no different with oolong and green tea.

Because green tea has been processed the least, it tastes most natural and earthy. Unfortunately most people find the taste in green tea lacking, with a flavor commonly described as “grassy”. Even with lemon and honey I find the flavor to be less than appealing.

Oolong tea has a variety of different flavors along with an enticing aroma, due to its longer fermentation process. Oolong tea also tastes earthy, but with hints of wood and citrus for a well-rounded flavor that doesn’t make you sick to your stomach at the smell.

Because taste is essential to something you have to drink for weight loss an a regular basis, the taste edge is given to oolong tea. However tasty is on the taste buds of the beholder, so you may feel differently.

WINNER: Oolong Tea

Round 4: Health Benefits

The health benefits of oolong tea have been proven to lower sugar levels in diabetics, reduce blood pressure and lower cholesterol. It’s heart smart and provides drinkers with a ton of energy without the twitchy side effects. In addition, oolong tea also gives your metabolism a kick in the pants so you can burn fat quickly.

Green tea has been applauded all over the world for its health benefits, which include lowering cholesterol and decreasing instances of bladder cancer in women. Some green tea studies have shown that women with ovarian cancer on a steady diet of green tea lived longer than women with ovarian cancer who didn’t drink green tea regularly.

Both green and oolong tea have been used to aid digestion, fatigue, and stress. More studies exist citing the advantages of green tea, but with such similar effects I have to say both provide equal health benefits.


As you can see for yourself, the hype behind green tea and oolong tea for weight loss is justified. The problem is that there’s just so much information that it’s difficult to discern what’s credible and what isn’t.

If you’re looking to lose weight and improve your overall health, you’ll do fine with either tea honestly. But for those of you making decisions based on scientific evidence, most of the science is on the side of green tea. That doesn’t mean there’s anything wrong with oolong tea–it certainly tastes better–it just means that some monk gave green tea the edge a long long time ago.

Try green tea for a week and then oolong tea, a cup in the morning and a cup before bed. See which tea fills you with more energy to work out, which makes you feel less stressed and healthier. Despite green tea’s “wins” over oolong, I still prefer the taste of oolong.

Keep in mind however that using tea for weight loss is only meant to supplement weight loss from a proper diet and exercise. If you’re getting regular physical activity and eating right, you can choose which tea you’d like to use to as your weight loss assistant.
