WATCH: Sugar Makes You Fat and Weak

People have been saying sugar is toxic as far back as 1972, when British professor John Yudkin wrote a book called Pure, White and Deadly, which sounds like a book about cocaine or heroin, but is actually about granulated sugar. He's sort of been redeemed after  Robert Lustig, professor of paediatric endocrinology at the University of California, gave the  ground-breaking lecture called Sugar: the Bitter Truth. Prior to that, Yudkin had nearly been driven out of academia by a food lobby that was focused on increasing the amount of sugar into virtually every food product. One of things that Yudkin said was that we'd  been eating things like butter for centuries, while sugar, until the mid nineteneenth century, was something of a rare treat.. "If only a small fraction of what we know about the effects of sugar were to be revealed in relation to any other material used as a food additive," he wrote, "that material would promptly be banned."

Cut to popular diets like Atkins, which is extradorinarily effective when you eliminate virtually all sugar and simple carbohydrates. I've done it a number of times and it's simply the most effective way to drop pounds, combined with exercise. And if you ever needed proof that sugar is a drug, the withdrawal you go through in the early days of the diet will prove it to you. Cut to virtually every recent article of repute, highlighting its toxicity and damage to the liver and the sky rocketng morbid obesity rates over the last twenty or so years. 

Now to add insult to injury, a recent study by The National Center for Biotechnology Information, says  as little as 75 grams of glucose leads to a 25 percent drop of testosterone. To put that in perspective, a 12 ounce bottle (the little ones) of Coca-Cola has 39 grams, so less than two of them! Low testoterone in men has been linked to depression, fatigue, lowered libido and erectile dysfunction.  So if you weren't worried about your waist line, maybe you'll worry about losing your mojo. The study included men with varying levels of metabolic health ranging from normal to type 2 diabetes.
