Every time you feel you need a cool drink, drink water instead of sugar loaded Diet and Regular Colas. Hard to do? Of course. But if you can't change one of the worst and most promoted bad habits in the world, then expect to stay fat and take years off your expected life span.
Sorry, I'm no Doctor but I have a 92 and going life span. Seldom do I drink any sugar loaded drink. Yeah, I protect my health in other ways too. I'm within 15 pounds of my weight at 26. You'll know if you read my older blogs. Look up "Obesity" by entering the word in the upper left hand corner of any of my blogs.
