When my dad was a 12-year-old kid in Red Bluff, California, circa 1928, part of the extended family was a man he knew as Uncle Jack Cotney. That they knew of, or he'd admit to, Uncle Jack had survived some 25 stand-up gunfights in his life.
Green tea is a fat burner that does speed up the metabolism, as far as energy drinks however they really speed up the heart not your metabolism. If you're looking for something that will speed up your metabolism there are better choices for that. Good Luck, Casey.
Commonly used in intermittent fasting, ketoproof coffee gives plenty of energy and a great satiated feeling throughout the morning fasting hours. Now, I want to explain this further. Drinking this coffee will break your fast from the night time, but it will ramp up your metabolism with caffeine and fats. This is to help you get through the fasting process in the 10+ hours ahead. Personally, I drink 2 cups of this in the morning â fast all day â and eat at 9pm.
