“I am generally not a fan of energy drinks,” Williams says. They are simply not good for you. There is no reason to have one when you can do a fresh juice. “It has the same purpose but no sugar, and it’s more natural,” he adds. Plus, most energy drinks have too much caffeine which can lead to high blood pressure and rapid heartbeat. Even better than a juice, drink a protein meal replacement shake. It will boost your energy right away if you’re hungry. Your body will pull whatever is immediately it the blood stream to function, Williams says. “Just keep it simple: Protein powder with some veggies and fruits. Don’t add a lot of stuff and use simple ingredients,” he adds.
