So today I decided to quit (or at least seriously cut back on) caffeine, artificial sweeteners, alcohol and carbs. So you can blame any behavior you don’t like on that – for a couple of days anyway. (And if you see me drinking a diet coke, please remind me that I’m cutting back!)

On that note, a new study (yet another study) shows that consuming fructose actually changes the way our bodies process sugar. Fructose is mostly commonly consumed as high fructose corn syrup that is added to just about every packaged food.

The researchers found that lipogenesis, the process by which sugars are
turned into body fat, increased significantly when as little as half
the glucose was replaced with fructose. Fructose given at breakfast
also changed the way the body handled the food eaten at lunch. After
fructose consumption, the liver increased the storage of lunch fats
that might have been used for other purposes.

I don’t think they’ve figured it out yet, but I think it’s fascinating that the calories in, calories out model is finally being challenged.
