Also, try comparing a shot of espresso to an average tall brewed coffee (around 8 oz). The latter actually packs in way more caffeine compared to the tiny shot of espresso. An average cup of black coffee would have 65-140 mg of caffeine while an ounce worth of an espresso shot would have 30-50 mg.
By volume, an average cup of joe has 8-15 mg of caffeine per ounce, and espresso still averages 40 mg per ounce. While this looks like espresso has more mg, ask yourself: can you actually drink 8 ounces of it in one sitting? Probably not (and we don’t recommend you do!)
#5: Is caffeine addicting?
This scene from Saved by the Bell may have been one of the reasons why some think caffeine is addicting.
But does caffeine really make a junkie in us coffee lovers?
The real deal:
While caffeine is certainly a stimulant and may cause dependency, a regular caffeine fix will NOT cause a drug-seeking addiction that threatens your overall wellbeing (which is what happens to drug addicts).
But getting off it abruptly may cause caffeine withdrawal. Symptoms include:
Rather than an addiction, caffeine obsession may be more accurately described as “dependency.” When you go without it, you experience withdrawal, all thanks to dopamine or that chemical that influences our motivation and emotions. When dopamine levels go higher because of caffeine, you go through that perked up feeling.
But caffeine doesn’t get it to that “high” level of stimulation. It’s just enough to make you feel more awake. As compared to other drugs that throw off the balance in the reward circuits in your brain that wires other people up and cause drug-seeking addiction.

#6: Does caffeine cause weight loss?
When you see supermodels caught by the paparazzi on their coffee run, it’s easy to think that caffeine is one of the reasons why they get to keep that Victoria’s Secret physique. So does caffeine really cause weight loss?
The real deal:
Caffeine can’t make you lose weight.
BUT… it can increase your metabolism! There are 3 ways it does this:
While caffeine is shown to contribute to weight loss and increased metabolism, having more caffeine doesn’t necessarily translate to burning more calories. The metabolic effects are based on certain factors, observed in studies only in the short-term, and are shown to diminish over time. Plus, consuming more than you’re supposed to can lead to adverse effects.
It’s always a good measure to keep your coffee or caffeine consumption in check and avoid caffeine just for the sake of losing weight. If you watch your caffeine intake you can keep enjoying each cup (or mint!) and embrace the added health benefits.
Erectile dysfunction. In combination, those are two of the ugliest words known to man. But can caffeine help you get it up?
Science hasn't found the definitive answer to this question, but one study concluded that fewer men who consume caffeine have problems performing. The study said:
Caffeine intake reduced the odds of prevalent ED, especially an intake equivalent to approximately 2-3 daily cups of coffee (170-375 mg/day). This reduction was also observed among overweight/obese and hypertensive, but not among diabetic men. Yet, these associations are warranted to be investigated in prospective studies
