Is a Calorie a Calorie?

It’s pretty rare that there’s anything worth reading in the semi-regular set of links that I receive from LinkedIn. However, this week was an exception. This excellent article by David Katz, M.D. really breaks down the calorie debate in an effective, clear, scientific fashion. For me the winning phrase regarding why people ignore the laws of physics to parrot other, murkier theories is simply this: where nutrition and weight loss is concerned, “desperation breeds gullibility.” I found this article worth a read:

    I get that in a closed system such as the human body is supposed to be, 3500 calories ingested above expenditure equals one pound of weight gain. The only thing I have read that would lead me to think otherwise is some research that I will look up when I’m awake that determined that differing intestinal fauna made a real difference in the nutrition extracted from food consumed. Their theses is that the bacteria in the gut can increase or decrease how many calories the body absorbs from the food it takes in.

    That said, yeah. Fat is only “bad” because it has 9 cal/gram instead of 4. Grains are only “bad” because some people’s digestive systems don’t deal well with them. From the perspective of weight loss, a calorie is a calorie. For feeling good, though, if I eat the same number of calories in veggies that I could eat in sugar, I’ll feel much better having eaten the veggies.
