Caffeine is a drug that stimulates the brain and nervous system, and it is found in many drinks such as coffee, tea, soft drinks, and energy drinks. Caffeine has both positive and negative health effects. Here are some details about caffeine and metabolism:
Positive effects:
- Caffeine increases the metabolic rate, which means it increases the rate at which the body burns calories at rest. Studies show that caffeine can increase resting metabolic rate by 3–11%, with larger doses having a greater effect.
- Caffeine promotes the release of fatty acids from fat tissue by raising blood levels of epinephrine (adrenaline), which can increase fat burning.
Negative effects:
- Caffeine can cause unfavourable acute effects on glucose metabolism.
- Caffeine can cause negative effects on glucose metabolism, especially in large doses.
- Caffeine can cause anxiety, irritability, trembling hands, sleeplessness, and rapid heartbeat (palpitations) .
Ingredients or materials:
- Caffeine is a stimulant substance that is proven to increase the release of fats from the fat tissues and boost the resting metabolic rate.
- Caffeine is metabolized in the liver by the cytochrome P450 oxidase enzyme system, in particular, by the CYP1A2 isozyme, into three dimethylxanthines, each of which has its own effects on the body.
In summary, caffeine can increase the metabolic rate and promote the release of fatty acids from fat tissue, but it can also cause negative effects on glucose metabolism and other side effects.
