It's kind of like measuring the performance of vehicles by looking only at the chemical energy of the fuel they use and how far they go on a given amount of fuel. Those seem like reasonable measurements, until you try to put jet fuel in a motorcycle or bunker oil in your car. The design, efficiency, and maintenance status of the engine matters a lot.

Your analogy is about as useful as saying 2-dimensional kinematics doesn't translate to 3-dimensional kinematics because it doesn't have a component for handling the third dimension.
- DougWebb 10y agoExcept it doesn't translate, when you're trying to handle the third dimension. And CICO isn't an effective basis for your diet when there are biological factors with large impacts that CICO simply doesn't address.
- jtuente 10y agoWhat large factors outweigh calorie content? There are plenty of dietary restrictions for things like Crohn's and diabetes, but they're easily worked around without changing overall calorie consumption. Hypothyroidism and other metabolic diseases can't cause weight gain without an overabundance of calories consumed. The fact that someone's BMR lowers because of them is not a bigger factor than how much calories a person consumes.
