Difference between black tea and green tea

Black tea and green tea are both made using the leaves of the Camellia sinensis plant. White and oolong tea are also made using the leaves of this plant.

But what is the difference and why do these teas have different names and all are made from one plant?

The main difference between black and green tea is in the production process. Green tea is not oxidized, while black tea undergoes the most complete oxidation process.

Here are two examples that show how the production process affects treating the tea leaves and why we get different teas at the end.

The production process of black tea

Black tea leaves are harvested and then dried to reduce moisture content. The leaves are then rolled by hand or by machine to create minuscule breaks in the leaves that allow enzymes to interact with the oxygen.

Rolled leaves are spread out on large trays where oxygen turns these leaves black. The final step is to stop the oxidation, and for this to be done black tea leaves are fired in ovens. The final step is packaging for sale.

The production process of green tea

Opposite to black tea, green tea is not oxidized in any way during production. The leaves are just harvested from the tea plant and heated to prevent oxidation and withering (remove moisture).

Then leaves are just pan-fried or steamed and retain a green hue that is most similar to the tea plant itself.

Black tea vs. Green tea for weight loss

As we mentioned above green tea leaves don’t undergo a 100% oxidation process, and this helps the tea to retain its key nutrients. The fermentation process for green tea ensures that more polyphenols are preserved and the lack of oxidation makes it rich in epigallocatechin gallate EGCG, an important antioxidant.

When it comes to black tea, the fermentation process reduces levels of antioxidants especially catechins which are associated with weight loss. However black tea is higher in caffeine which has also been shown to help control weight.

How green tea can help you lose weight

Caffeine and EGCG may have powerful effects on metabolism

Many studies show that drinking a cup of green tea increases the number of antioxidants in your bloodstream. Green tea is loaded with potent antioxidants called catechins and the most important of these is EGCG, a substance that can boost metabolism.

Another compound present in green tea also known as a stimulant is caffeine – it has been found that caffeine aid at burning and also improve exercise performance numerous studies. A cup of green tea contains 30-50 milligrams of caffeine which is much less than a cup of coffee 100-200 milligrams.

Increases fat burning

In a study where were examined the effects of a combination of regular exercise and tea catechins on energy expenditure was found that tea catechins increased fat burning during exercise and rest.

Many other studies confirm that EGCG boosts the burning of fat which may lead to reduced body fat in long term.

If you look at every commercial weight loss product you’ll likely see green tea named among other ingredients. This is a green tea extract that is linked to increased fat burning during exercise.

There is a study where a man who took green tea extract before exercise burned 17% more fat than a man who didn’t take this supplement.

Makes the body’s metabolism more efficient

Some studies suggest that green tea can boost metabolism and help to burn 3-4% more calories each day. The results of these studies showed that taking green tea extract and EGCG supplements can make you burn more calories.

If a person burns 2000 calories per day, this increase of 3-4% will result in an additional 60-80 calories spent per day.

However, not all studies show that green tea boosts metabolism. The effect may be individual and also metabolism-boosting effect persists in the long term.

How black tea can help you to lose weight

Low-calorie drink

Black tea only has 2 calories per cup. If a cup of black tea contains more than 2 calories it’s linked to other products added to it like sugar or milk.

So the best way to use black tea for weight loss is to take it on its own, without adding sugar, milk, or honey.

Keep in mind that black tea also contains tannins, and these are the substances responsible for its strong flavor. Tannins are harmless when consumed moderately, but drinking too much black tea can upset the stomach and cause nausea or vomiting.

So even it is a low-calorie drink don’t overdrink it.

Changes in gut bacteria

According to a study published in 2017 by the European Journal of Nutrition black tea along with the assistance of a specific mechanism through the gut microbiome, contributes to weight loss.

This study also shows that consuming black tea can decrease gut bacteria associated with obesity and increase gut bacteria associated with lean body mass.

Caffeine boosts metabolism

Caffeine in black tea may increase metabolism by 6% and also encourages the body to undergo lipolysis or the breakdown of stored fats.

keep in mind that if you drink too much black tea or coffee that will not help you to lose more weight. The daily recommended dose of caffeine is 200 -300 mg, caffeine levels in black tea vary from 50 to 90 milligrams per cup (8oz), so don’t drink more than 3 cups per day.

People who are sensitive should also be aware of the side effects of consuming too much caffeine, and this is also for people with high blood pressure and irregular heart rhythm.

Good To Know: Drinking more caffeine doesn’t mean better metabolism. You can consume up to 400 milligrams of caffeine per day to be safe, recommended no more than 200-300 mg, which is equal to 3-4 cups of black tea.

If black tea is too strong for you or you simply don’t like the taste but still want to add it to your daily drinks then adding lemon to it is going to make a flavorful difference. Black tea and lemon are great combinations that also can fit in your weight loss program.
