Researchers in Canada say if you want a bigger energy boost that will last throughout the day-- drink less coffee.
To find out if their theory was true, they compared the energy levels in 21 healthy men and women. Some of them were regular coffee drinkers and some drink less than one cup a day.
After exercising just a few hours after drinking over six cups of coffee or a placebo, researchers found that the real caffeine boosts lasted longer than the placebo group.
However, the big winners turned out to be the people who weren't regular coffee drinkers. Their energy boost ended up surpassing regular coffee drinkers.
Blood tests showed the effect of caffeine was still present much longer than the regular caffeine users.
Researchers now conclude that cutting back on coffee may help the so-called "java jolt" last longer.
