"In the Key’s semi-starvation study (high-carb, low-fat) the subjects starved and obsessed on food constantly. In the Yudkin study (low-carb, high-fat), the subjects, who had no restriction on the amount of food they ate, volitionally consumed the same number of calories that the semi-starvation group did, yet reported that they had “an increases feeling of well-being.” Instead of lethargy and depression reported by the Keys subjects on their low-fat, high-carb 1570 calories, those on the same number of low-carb, high-fat calories experienced “decreased lassitude.”
Both groups of subjects were consuming the same number of calories, but one group starved while the other did just fine. One group had to be locked down to ensure they didn’t eat more than their alloted 1570 calories; the other group voluntarily dropped their intake to 1560 calories and felt great. What was the difference? Subjects in both groups ate the same number of calories."
"Ever since I started what I call the Evolutionarily Appropriate Diet (i.e., paleo, caveman, hunter-gatherer... etc.), I've refrained from counting calories--after all, if what I'm eating is "appropriate," I shouldn't need to. But since I've been uping the intensity of my weight training this summer, I have worried a little about whether or not I'm getting enough protein.
In any case, I typed in a few days to see roughly where I'm at. It turns out that I'm eating more than 5000 calories a day.
Today was 5,238. Yesterday was more. That pigout day I had last week came in at 6150 calories. And I've been pretty much eating this way the whole time I've been on this diet--in other words, I've been rapidly losing weight while eating 5000+ calories a day.
Gary Taubes explained in Good Calories, Bad Calories that not all calories are the same, but the idea that I could be eating like this and still losing weight just floors me. The "caloric balance" calculator on FitDay (which takes into account exercise levels, etc.) suggests that I should be gaining 3.6 pounds a week. Instead I've lost a total of 50 pounds from my all time high.
Need any more proof that a calorie is not just a calorie?"
