According to Chatbot BARD, green tea also suppresses hunger:
Yes, green tea can suppress hunger. It contains catechins, which are compounds that have been shown to boost metabolism and suppress appetite. Catechins work by increasing the production of heat in the body, which is known as thermogenesis. Thermogenesis helps to burn calories and can lead to weight loss. Catechins also help to increase the levels of certain hormones that suppress appetite, such as leptin and adiponectin. Leptin is a hormone that tells the brain that you are full, while adiponectin is a hormone that helps to regulate blood sugar levels and reduce inflammation.
In addition to catechins, green tea also contains caffeine. Caffeine is a stimulant that can help to suppress appetite by increasing the levels of adrenaline in the body. Adrenaline is a hormone that helps to increase the heart rate and blood pressure, which can lead to feelings of fullness.
A study published in the journal "Appetite" found that people who drank green tea before meals felt fuller and ate less than those who did not drink green tea. The study also found that green tea drinkers had lower levels of ghrelin, a hormone that stimulates hunger.
Another study published in the journal "Nutrition and Metabolism" found that people who drank green tea for 12 weeks lost more weight than those who did not drink green tea. The study also found that green tea drinkers had lower levels of body fat and waist circumference.
Overall, the evidence suggests that green tea can suppress hunger and help with weight loss. However, it is important to note that green tea is not a miracle cure. It is important to combine drinking green tea with a healthy diet and exercise to see the best results.
