In response, Christian nutritionist Beck said, although true coffee can increase metabolism, but the effect is not long.
"Caffeine can improve athletic performance, both in increased speed, strength, and endurance, while providing psychological benefits by making exercise easier," Beck said.
"Coffee can also suppress the appetite because it makes the stomach feel fuller, and at the same time gives a boost of energy. But relying on coffee alone as a source of energy is not enough, because the effect is short, "he explained.
While Alex Hodge, a gastroenterologist and liver disease at Monash Health, Melbourne, Australia said, "In general coffee is good for you. Coffee drinking habits are also associated with decreased neurological conditions such as Parkinson's and Alzheimer's, as well as lower risk of developing type 2 diabetes. "
"In addition there is growing evidence, though not much, that coffee lowers the risk of some cancers including colon, liver, ovarian, pancreatic, throat, and endometrial cancers."
