…Or at least that’s the conclusion Sara Chodosh has come to, in her article, Sorry, Keto fans, you’re probably not in ketosis. It’s just too hard, she argues in her piece for Popular Science. Unless it’s brutal, you’re probably not doing it right.

The reason for this is the diet’s 80 – 90 percent necessary fat intake, with only 10 – 15 grams of carbohydrates to round it out. Even a small apple can put someone over this carb limit, and so few carbs of any kind is hard to maintain, and it’s certainly not an enjoyable lifestyle. As for getting that much fat in a day, the article says, “It involves eating a lot of rich, heavy foods with little variety—think fatty meats and gravy on cauliflower.”

A lot of people who claim to be in ketosis get their fats from grass-fed beef and similar sources, but too much protein inhibits the body’s ability to drop into keto; instead of burning glucose, the body instead starts burning that protein as carbs. On the other hand, one can’t do no protein, because protein is necessary to manufacture hormones and hair and nails and muscle. So getting into ketosis isn’t just challenging because the diet, itself, is so hard to maintain. It’s also difficult just to find the right balance of things to eat, to get to ketosis in the first place.

Not that it’s impossible. In fact, ketosis is sometimes prescribed to people with severe epilepsy, and the diet seems effective for these patients. But in these situations, the keto diet is usually prescribed under the care and supervision of doctors and trained nutritionists, not left to the discretion of Internet articles. The fact that so much medical intervention is required in these situations, and that keto is never suggested to be a long-term lifestyle, suggests that the trend includes scores of dieters who probably aren’t doing it right. It’s just too dangerous, too tricky, too aescetic, and overall not sustainable.
