Keto Diet Theory Put to the Test


Video Transcript:

“Testing the theory of the keto diet” When you don’t eat enough carbohydrates, you force your body to burn more fat. However, this increase in fat burning it is often misinterpreted as being faster of reducing lean body fat. But this neglects the fact that the ketogenic diet fat intake also increases dramatically. The question is what happens to the overall body fat balance. One cannot empty a tub by extending the sewer, if it develops the faucet at the same time. However, advocates of a low carb diet have a theory, the so-called carbohydrate-insulin model of obesity. Low-carb diets, whether ketogenic or or some more common form of carbohydrate restriction, consider the reduced production of insulin would result in less fat storage; so even if you eat more fat, less will stick to you. So we will burn more and accumulate less, the perfect combination to remove excess fat – or at least according to this theory.

In truth, instead of just speculating about it, they decided to test if so. Gary Taubes creates the Nutrition Science Initiative, to sponsor studies to prove the carbohydrate-insulin model. He is the journalist who wrote the controversial A 2002 article in the New York Times magazine “What if everything is a big fat lie?” which tries to turn the dogma of eating upside down by arguing in support of the Atkins diet with their cheeseburgers with bacon without the bread, based on the carbohydrate-insulin model. (Much of Nina Teicholtz’s book, “The Big Fat Surprise,” is simply a reproduction of Taubes’ earlier work). In response, some of Taubes’ researchers themselves are cited as supportive his thesis, accuse him of distorting their words. “The article is incredibly misleading,” says one of them, “I was horrible.” “He got this weird little idea, then spread it and people believed it, “another says.

What a disaster. It doesn’t matter what people say. All that matters is science. Taubes raised $ 40 million in funding about his Nutrition Science Initiative to prove to the world, that a person may lose more body fat on a ketogenic diet. They agreed with a well-known researcher from the National Institutes of Health, Kevin Hall, conduct the study. Seventeen overweight men were effectively locked up into something called a metabolic ward for two months, to allow researchers full control over their nutrition. For the first month they were put on a typical high carbohydrate diet (50% carbohydrates; 35% fat; 15% protein), and then switched to a low carbohydrate ketogenic diet (only 5% calories from carbohydrates; 80% from fat) for the second month.

Both diets have the same number of daily calories. So if calories are calories when it comes to losing weight, then there should be no difference in body fat loss of your usual diet compared to the ketogenic diet. However, if Taubes was right, if the calories from fat are somehow less fatty, then fat loss will accelerate. What happened instead, in this funded study from the Nutrition Science Initiative, is that fat loss in the body slows down when switching on a ketogenic diet. Wait a minute, why do people think the diet works, if it actually slows down fat loss? Well, if you just look at the scales in the bathroom, a ketogenic diet would seem like a smashing success.

They started to lose weight by less than half a kilo a week on their usual diet in the two weeks before switching to 1.5 kg weight loss. within seven days after switching to a ketogenic diet. But what happens is their body, tells a completely different story. The rate of fat loss slowed by more than half. So, most of what they lost was just water. (The reason they started to burn less fat on a ketogenic diet, probably because without the preferred fuel, carbohydrates, their bodies began to burn more than their own protein.) And that’s exactly what happened. Switching to a ketogenic diet led to them losing less fat and more fat-free mass; also lost more muscle mass.

This can help us explain why the leg muscles of people who train cross fit, when put on a ketogenic diet, they can decrease up to 8%. Vastus lateralis is the largest muscle in your leg, reduced by 8% in thickness on a ketogenic diet. Yes, the study participants began to burn more fat on a ketogenic diet, but they ate so much more fat on a ketogenic diet that eventually started to retain more fat in your body, despite lower levels of insulin. This is “diametrically opposed” to what the keto crowd is predicting, and this from the person who was paid to support their theory. In scientific terms, the carbohydrate-insulin model “Failing our experimental exam.” In light of this “experimental forgery” of low-carb theory, The Food Science Initiative effectively disintegrated… but based on their tax returns, not before Taubes and his co-founders have personally made millions of dollars in compensation.
