Personally, I'm still convinced that a calorie is a calorie.
According to this New York Times article[1], a calorie is not always a calorie:
A food isn’t a food — they’re all different — but since a calorie is just a measurement of energy, how can it vary? When I asked my question, Nestle’s answer was confounding: “Yes and no,” she said, adding, “It’s Talmudic.” Because calories change as they enter the body, the nine grams for fat and four for everything else turn out to be not very accurate measures at all; besides, foods are only rarely one thing or another.
Here’s what is true, she said: “The studies that have measured calorie intake, that have put people on calorie-reduced diets and measured what happened, show no difference in weight loss based on composition of the diet.” When people are essentially incarcerated, when all intake is weighed and measured, they will lose weight if the calories in their diets are reduced — regardless of the composition of the diet.
