Are Diet teas and Weight Loss Teas Good for You?
Posted on May 01 2023
What is a diet tea?
A diet tea is a tea that is marketed as a way to help an individual lose weight through cleansing or detoxing. Diet tea is also known as slimming tea, teatoxes or weight loss tea, and whilst it does help you temporarily lose weight, the loss is in the form of faecal and water weight, which means that the weight does not have a lasting affect.
If you are going to incorporate a weight loss tea into your diet, you should only do it short-term due to the side effects it causes.
What are the side effects of diet teas?
Diet teas are made from Senna, an FDA-approved non-prescription laxative. Senna is used to help treat IBS, haemorrhoids and constipation. It is also used to clear out the bowel before a colonoscopy. Senna has a number of side effects, including:
- Stomach pain,
This is because Senna forces food to move through the digestive tract at a much faster speed, making the colon incapable of absorbing water, and resulting in more frequent bowel (and looser) movements. It also causes abdominal pain and/or cramps. In some instances, it causes consumers to feel sick and vomit.
Due to the dehydration caused by weight-loss tea, it might change the colour of your urine to a dark yellow-brown. Some rare side effects have been associated with acute diarrhoea - bloody faeces, dizziness and weakness.
Why are diet teas bad for you?
If you use diet teas for a long period of time, you are at risk of causing serious damage to your digestive system because of the laxative, Senna. Long term use of teatoxes can stop the bowels from functioning normally, and may cause a reliance on laxatives. It can also alter the balance of electrolytes in the blood. Long term use can also cause
- Heart function disorders,
- Liver damage,
- Muscle weakness.
2013 and 2015 saw a spate of lawsuits made against Truong Giang Corp. (TGC) with their Herbal tea and Three Queen’s Ladies tea. They were sued after people claimed that they were misleading consumers about the health benefits of their products. Bootea Detox tea was also blamed for a spike of unplanned pregnancies, after it was found that Bootea stops the contraceptive pill from working due to its fast laxative properties (find out more here).
Who shouldn’t use diet teas?
Many diet tea manufacturers contraindicate diet tea for those with electrolyte disturbances, potassium deficiencies, heart disease, dehydration, gastrointestinal conditions, and those on long-term medication.

Pu-erh tea also boasts high levels of polyphenols including flavonoids, theaflavin and catechins that have high antioxidant activity. These chemicals help to aid digestion as they speed up the fat burning process and act as a sponge. The fermentation process of pu-erh tea produces beneficial microorganisms that you won’t find in other teas, Pu-erh tea helps with the following:
