Don't know if this has already been posted so here's a link to an interesting article about how the calorie content of some foods may be different in our bodies than in the laboratory:

    When I first read that study about the almonds, I was definitely curious about how the same principle might apply to other foods... interesting!

    Certainly makes one wonder about other foods, avocados for example.

    Interesting. I'd never thought about how much of the food was absorbed by the body. I knew calorie counting was pretty squishy, but I'd never thought about that aspect of it before. I wonder if there is individual variation in how much is absorbed, or if there was a pretty constant amount between subjects. I might have to track down this study.

    Interesting but I wonder if absorption rate is individual?

    I know that calorie counting is not exact, but it is the best method I have of controlling my food intake. Bigger portions/Junk food tend to be higher in the lab calories, so I eat less. It's psychological. If believing that eating 1 more piece of pizza is going to put me over, and I don't do it, then that's effective to me, regardless of whether the number at the end of the day is exact.

    When I do count my calories, it's more about accountability and awareness than exactness (is that a word?). We are constantly learning how much we *don't* know about nutrition and food.

    It's all relative and estimations anyways. That's why I always add or take away calories based on percentages.

    Very cool article, thanks for sharing. It really does give credence to the idea that a calorie is not just a calorie, and eating a healthy diet is better than eating a low-calorie one of junk food.

    Agree. Not just food but exercise. But as long as I'm aware and accountable, I can figure out where things are and aren't working and adjust accordingly.

    While this article appealed to my "inner bean-counter" I fully agreed that counting calories and choosing wisely is an effective tool to losing and maintaining. :smile:

    Certainly, the notion that the energy released by burning it not being the same as that digested isn't new! In my chemistry lesson in 1985, my teacher warned me that it wasn't the same as digested calories when we burnt a peanut.

    That's an interesting article. I'm kind of sad that the body doesn't fully absorb all the nutrients.
