Red Bull & weight loss?
Originally Published: January 21, 2011
Unfortunately, the magic recipe for high energy and weight loss does not come in a can. Energy drinks (including Red Bull) contain high amounts of caffeine, which may make you feel more alert and knock out feelings of fatigue and boredom. It is likely that your theory is based on the idea that caffeine can slightly increase metabolism. However, research suggests that sugar-free energy drinks are not good products for weight loss.
Assuming that a person ingests enough caffeine to produce a significant increase in metabolism, it would still take a month for that person to lose a pound of fat. Moreover, the level of caffeine in energy drinks only slightly increases metabolism (burning less than 100 extra calories per day). Keep in mind that these increases in metabolism cease when the person quits his or her caffeine-gulping habits. Also, caffeine is a diuretic. This means that any initial weight loss is most likely due to lower levels of water in the body.
Increasing your consumption of energy drinks (or caffeine) to levels that will increase your metabolism is not recommended. High levels of caffeine can cause unpleasant physical and psychological effects. These include:
- Caffeine dependency
- Muscle twitching
- Heart palpitations
- Ulcers and gastroesophageal reflux disease
The caffeine and taurine content of energy drinks can cause blood pressure and heart rate to increase by as much as 10%. For healthy individuals, this is not a huge problem, but for hypertensive individuals, excess caffeine may lead to increased risk of heart disease or stroke. For the sugar-free fiends, research on artificial sweeteners is mixed; some results show that artificial sweeteners can help weight loss, while others conclude that artificial sweeteners contribute to weight gain as well as increasing risk for certain cancers. Nonetheless, sugar-free red bull has 100 less calories than a regular red bull.
Although this myth-busting answer may be disappointing, have no fear. There are many ways that people (even busy college students) can increase their energy and maintain a healthy weight without relying on energy drinks.
