Say the word “coffee shot” to two people in a bar or a restaurant and the first reaction might be a skeptical one. Why shoot yourself up with something that’s already been through the digestive system? It’s painful!
But if you actually go to a medical doctor and ask them to try it for you, you might be surprised at what they can do for you.
Joe Marker is one of the leading doctors who gets into the act. He has tried — and loved — countless caffeine enhancing drinks from coffee to energy drinks.
And in many cases he gives patients the opportunity to come to him and have them shot in the stomach. It’s not something doctors recommend necessarily, but they say it’s the ultimate way to dilute the caffeine without the dangers of additional calories.
CNN spoke to Dr. Marker to find out more about how they work and what the side effects are.
10 cups of coffee, in one shot
Sometimes people will think they need coffee drinks because they’ve overate and feel a sense of energy. Dr. Marker says a coffee shot will not give you that feeling. In fact, in his opinion, it probably won’t help much at all, as the caffeine provided by the shot of coffee is significantly less than the entire coffee they have drunk beforehand.
On the flip side, it can give you a boost of strength if you are inclined to work out. You’ll feel generally alive and if you’re serious about that, you might be able to train much harder or longer. So once people have tried a coffee shot they will usually find it easier to do yoga, walking and running with their friends, the doctor said.
When it comes to sleep the coffee shot certainly does help. Too much caffeine in the morning can disrupt the night’s sleep, and if it disrupts your sleep too much you will be ill during the day.
But once again, the reason the coffee shot might help you sleep well is because it contains very little caffeine. So if you don’t drink that many cups of coffee you won’t have an issue while doingze off.
As for drinks like coffee, tea and alcohol, the caffeine added to those other beverages causes it to act more like sugar than like natural sugar.
Dr. Marker says if you drink a standard cup of coffee at 70 ml the amount of caffeine in it is equivalent to all of the sugar in a cup of tea. The same cup of coffee is the equivalent of 12 ice cubes.
You might feel less tired afterwards and start nodding off to sleep but that won’t be because of the caffeine in the coffee, it’s just from the sugar in the tea, as the amount of caffeine in the tea isn’t enough to wake you up. It’s something just in between.
When it comes to coffee shots, the extra caffeine, sugar, milk or the sugar in the shot itself only helps to dilute it. It won’t help you achieve any strange kind of effect.
Similarly to the breakfast milk shot, don’t think for a second that putting a shot of milk in your coffee helps you stay awake. In fact, some studies suggest that it might even be bad for you. One such study found that people who drink coffee with milky milk have a greater risk of having a heart attack.
“Too much coffee and too much milk is like a bad combination for heart health,” said Dr. Marker.
