A colleague asked me if I thought a recent article in the New York Times on the health effects of the ketogenic diet by Anahad O’Connor was balanced. In a superficial sense, the answer might have been “yes.” Mr. O’Connor considered pros and cons, noted opposing views by relevant experts, cited some salient concerns, and acknowledged the absence of much relevant evidence- notably, longer term effects.
Diet in our culture all too often is a verb; as in “dieting.” We “diet,” or perhaps worse, “go” on a diet.
One could be forgiven for thinking that to consider healthcare a right rather than a privilege, you need politics inclined left of center. I rather doubt that is true, however - and a thought experiment will show why.
I recall when the current occupant of the White House was campaigning as the “law and order” candidate. I was disaffected then, knowing such bluster was disconnected from any genuine commitment or cogent plan to stay the hail of bullets in America. I am disgusted now, as more massacres of unsuspecting innocents punctuate the drowsy lassitude of mid-summer like lightning searing the sky.
The recently published CALERIE trial should sound the death knell of every fad diet that ever was, is, or would be (it won't, of course). The study showed, in the proverbial nutshell, that calorie restriction, per se, causes weight loss in the overweight, which in turn causes an array of improvements in the customary measures of cardiometabolic risk.
