Guarana, a caffeine-rich shrub native to the Amazon, is used in energy drinks and dietary supplements to boost energy and metabolism. However, it should be used in moderation due to its high caffeine content and potential side effects. Those with anxiety or heart problems should avoid it.
Guarana is a shrub whose seeds are very rich in caffeine: they contain approximately two to three times the caffeine content of most coffee beans. The herb is said to stimulate mental and physical energy while reducing appetite. For these reasons, plus the fact that guarana is naturally grown, the guarana diet is a popular way to lose weight. However, guarana is only recommended for use in moderation simply because it is so high in caffeine.
This creeping shrub is native to the Amazon basin in South America and is related to maple plants. It is often used in energy drinks, teas, and some soft drinks and is even used as the primary source of caffeine over coffee in its native regions. Studies have shown that guarana can increase memory retention, reduce appetite, and increase physical stamina. Supporters of the guarana diet often rely heavily on these findings to market products. A guarana diet typically does not involve eating the plant, but instead focuses on consuming supplements and beverages high in the herb to boost energy and metabolism.
Guarana dietary supplements mostly come in pill, drink, and powder forms. Beverages can range from juices to teas to fizzy drinks, but it is generally recommended to limit the amount of sugar taken with guarana, so soft drinks are not typically used in the diet. The powder can be a convenient way to make guarana drinks on the go, because they usually just need to be mixed with water. As with any dietary supplement, it is recommended that those on the guarana diet read and follow the instructions carefully.
This plant is used primarily for its caffeine content, so addiction can occur after prolonged use. While using the supplement, some experienced nervousness and high anxiety. Usually, the solution to these symptoms is simply to reduce the amount of guarana taken. Side effects reported after finishing the guarana diet are headaches, moodiness, and other symptoms associated with caffeine withdrawal. Some have reported weight gain once guarana use has stopped.
Before starting any diet, it is generally recommended that a person speak with a medical professional. Those who have anxiety or heart problems or who may be pregnant may be advised by a professional to avoid guarana. Even a healthy adult should be cautious when using the extract, especially in combination with any medication or other supplement.
