Research suggests that coffee can’t kickstart metabolism for obese people
We love our morning cup of coffee. But how important is caffeine in our weight loss journey?
 
When it comes to the connection between caffeine and weight loss, there are three common claims...
 
1 Research suggests that consuming caffeine can jumpstart your metabolism and help you burn fat. One study, for example, found that in the three hours after consuming coffee, metabolic rates were significantly higher in those who drank coffee than those who did not.
 
2 Another common belief is that caffeine boosts your energy level. The theory here is that the energy boost will make you more motivated to exercise, help you exercise for a longer time, or both. In fact, the International Olympic Committee puts a limit on caffeine intake for athletes so as not to give them an unfair advantage.
 
3 Coffee is often cited as an appetite suppressant. This suggests that drinking the caffeinated beverage could lead you to eat less.
 
But
It’s definitely tempting to believe that caffeine is the answer to your weight-loss woes. But there are several reasons why consuming caffeine won’t necessarily lead to shedding those extra pounds. Plus, consuming too much caffeine can be dangerous.
 
Studies do show that caffeine intake can increase your metabolism, but the effects only last for a few hours and the effects are much less pronounced in obese people. In other words, people who need to lose significant amounts of weight are much less likely to have their metabolism boosted by 
caffeine. 
 
As for exercise performance, studies really only show that caffeine can help boost energy for short workouts (about five minutes) and for endurance exercise done by trained athletes. There isn’t much evidence that caffeine has a positive effect on mid-length, moderate workouts.
 
The appetite suppression claim is probably just that: a claim. One of the only studies on the subject found that drinking coffee had little to no effect on 
participants’ appetites. Plus, people grow tolerant of coffee pretty quickly, so any positive effects tend to be short-lived.
 
Even if caffeine does help some with weight loss, it’s likely that any positive effects would be outweighed by the extra calories people tend to consume when they get caffeine in the form of sweet beverages. Coffee and tea are often drowned in cream and sugar, and it’s no secret that coffee-shop concoctions can be super high in calories. And soda, iced tea, and many other bottled caffeinated beverages can also be high in sugar, carbs and calories.
 
How much does it take to kill someone?
Too much of anything can be deadly. For instance, it would take 70 cups of coffee to kill a roughly 150-pound person. Death can also result from consuming 13 consecutive shots of alcohol, six litres of water or 48 teaspoons of salt. Being 9 feet tall can also kill you, from the combination of stress on the circulatory system and on the bones. Eating 85 chocolate bars can be deadly, too.
 
Warning!
Caffeine is a diuretic, which means it will contribute to losing some water weight on a short-term basis, but too much can be dangerous in the long run. Always be sure to stay hydrated!
