One Month of Cutting out Carbs and Sugar Made This Man Pre-Diabetic

So many people wonder which diets really work the best for them personally.  What if you had another version of you to test things out?

After Xand Van Tullenken gained weight, he realized that he and his twin brother Chris knew very little about losing weight and eating a healthy diet. So they set upon a unique experiment, going on very different diets for one month to compare results.

Xand's eating habits changed to exclude carbs and sugar while Chris cut out fat. What happened may surprise you.

Xand says he ended up losing eight pounds but in one month, became pre-diabetic.

""I cut out vegetables," he says.  "Literally, it was meat, cheese, eggs & fish."

Chris says his brother's diet was antisocial and adds, "For me, any diet you're going to go on has to be sociable, it has to be palatable, and you have to do it for the rest of your life."

    Instead of eliminating ALL carbs, had he eliminated "white" foods such as refined sugar, potatoes, regular pasta and white bread and included vegetables and legumes he would have a diet that was, indeed sustainable.

    This is quite misleading. The diet that restricts carbs and sugar (not eliminates but limits) is called the ketogenic diet. This guy reached the state of ketosis l meaning that your body has no carbs to burn so it's burning fat reserves. This physician, like many, is confusing this with ketoacidosis which is much more extreme. The ketogenic diet has been used since the 1920s to treat epilepsy.

    I loved that you did this comparison, but I must have missed the conclusion that would tell me which is better...I get that neither is better (?) Did this experiment help you find the perfect meal plans and what were they? WOW...eliminating carbs and sugars made you pre-diabetic!
