Good Calories, Hooray!
This means there are obvious limitations to the traditional model of counting calories to achieve weight loss.
And yet, using calories a measurement is still one of the handiest tools we have for assessing the relative dietary impact of various foods and serving sizes.
For example, when you are contemplating a "healthy smoothie" at some new takeout place you've never heard of, does it make a difference if the smoothie comes in at 175 calories versus 935 calories? Well, for many of us: F--ck yeah! We may still reject the 175 calorie version if it's full of Bad Things, but I don't care how much seaweed or spirulina or other virtuous antioxidant-rich secret sauce is in the 935er, I ain't going there.
But sadly, even though many of us have had reasonable success in the past counting calories to lose weight, it turns out it's way more complicated than keeping a fastidious record of Ins and Outs. And new research has turned up even more reasons why that reassuring number on your Lean Cuisine lasagna or your Skinny Cow treat or your Expensive Organic Exotic Granola Bar may be full of crap.
On the other hand, it's not all bad news: there may be other stuff in your kitchen that you feel guilty about that you could be scarfing up gleefully.
Let's look at some interesting specifics, shall we?
