Great news! The trial of Professor Tim Noakes is finally completely over, and he has been definitely found innocent. Professor Noakes was first acquitted in April 2017, but that decision was appealed. This appeal has now been dismissed, finally ending the four-years long trial.

“Keto is not easy to maintain, it’s not a palatable diet,” says Andrea Giancoli, a dietician and nutrition consultant in California. Getting 80-90 percent of your calories from fat—which is what’s required for keto—is actually difficult. It involves eating a lot of rich, heavy foods with little variety—think fatty meats and gravy on cauliflower. You’re only allowed 10 to 15 grams of carbohydrates per day, and though many dieters stretch that to more like 20 or 30 grams that’s still only about one banana. A single apple could also get you past that limit depending on its size.
But the real problem isn’t going over your carb limit—it’s the protein. “If you’re eating a lot of protein, you’re breaking that down into carbs,” Giancoli explains. Your body is in desperation mode on keto, she says, and without a reasonable supply of carbohydrates coming from grains and fruits, you’ll start breaking down the amino acids in proteins to make glucose. Glucose, though it sounds like a scary sugar, is your body’s primary source of fuel. Too much isn’t good for you, but you need some just to allow your cells to function normally.
The point of keto is to force your body to deplete its glucose (and the stored form, glycogen) so it will have to use body fat as a fuel source. It’s capable of making ketone bodies from your fat, which can replace glucose as an energy-storing molecule. To do that, you have to break apart fat molecules thus ‘burning’ the fat off. But here’s the thing: your body really really doesn’t want to run out of glucose. No glucose means starvation as far as it’s concerned. And when you’re starving, your body will start to break down protein just to get those sweet, sweet carbs. Of course, you have a source of protein in your body already: your own muscles. “When in starvation mode, your body breaks down muscle in your body,” says Giancoli. “Ketosis is a way of trying to preserve that protein. It’s not ideal, but it’s your body’s way of saving you.”
So far it sounds like real science but the conclusion of above article is like this:
"So maybe not being in ketosis isn’t so bad after all—now just cut back on the saturated fats".
Holy Cow! This indicates that the author has not read Richard Feinman’s “The World Turned upside down: 2nd Low carb revolution”. If you are interested in true science with supporting evidence from basic science, please see here.
The following is extracted from a Biochemists's book:
The key principle is that carbohydrate, directly or indirectly, through insulin and other hormones, controls what happens to ingested fatty acids. Carbohydrate is catalytic, that is, exerts its effect on other nutrients. The fat in the big Mac will not constitute any risk if you chuck the bun. Scientific evidence shows that dietary saturated fat, in general, has no effect on cardiovascular disease, obesity or probably anything else, but plasma saturated fatty acids do have effects. If you study dietary saturated fatty acids under conditions where carbohydrate is high or, more important, if you study effects in rodents where plasma fat better correlates with dietary fat, then you will confuse plasma fat with dietary fat. In humans, as opposed to rodents, saturated fatty acid in your blood is not equivalent to saturated fatty acid on your plate! In other words, if you eat high saturated fat diet & carb content is low, your plasma saturated fat will not rise. Lipophobes often cite rodent studies in which plasma saturated fat increase when they consume high saturated fat diet. You cannot extrapolate rodent data to humans in this respect!
