NuSI contracted noted researcher Kevin Hall from the National Institutes of Health to <\/span><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/27385608\/\" target=\"_blank\" rel=\"noopener\"><span data-contrast=\"none\">perform<\/span><\/a><span data-contrast=\"auto\"> the study. Seventeen overweight or obese men were effectively locked in what\u2019s called a metabolic ward for two months to allow researchers total control over their diets. For the first month, they were placed on a typical high-carbohydrate diet (50 percent carbs, 35 percent fat, 15 percent protein), then were switched to a low-carb ketogenic diet (only 5 percent of calories from carbohydrates and 80 percent fat) for the second month. Both diets had the same number of daily calories. So, if a calorie is a calorie when it comes to weight loss, there should be no difference in body fat loss on the regular diet versus the ketogenic diet. If Taubes was right, though, if fat calories were somehow less fattening, then body fat loss would become accelerated on a keto diet. Instead, in the very study funded by the Nutrition Science Initiative, researchers found that body fat loss <\/span><i><span data-contrast=\"auto\">slowed<\/span><\/i><span data-contrast=\"auto\"> during the ketogenic diet.<\/span><span data-ccp-props=\"{&quot;134233279&quot;:true}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">Why do people think the keto diet works if it actually slows fat loss? Well, as you can see in the graph below and at 3:40 in my <\/span><a href=\"https:\/\/nutritionfacts.org\/video\/keto-diet-theory-put-to-the-test\/\" target=\"_blank\" rel=\"noopener\"><b><span data-contrast=\"none\">video<\/span><\/b><\/a><span data-contrast=\"auto\">, if you <\/span><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/27385608\/\" target=\"_blank\" rel=\"noopener\"><span data-contrast=\"none\">looked<\/span><\/a><span data-contrast=\"auto\"> only at the readings on bathroom scales, the ketogenic diet would seem like a smashing success. Participants went from losing less than a pound a week on the regular diet during the first two weeks of the study to losing three and a half pounds within seven days after switching to the ketogenic diet. What was happening inside their bodies, however, told a totally different story: Their rate of body fat loss was slowed by more than half. So, most of what they were losing was just water weight. It\u2019s presumed the reason they started burning less fat on a ketogenic diet was because, without the preferred fuel of carbohydrates, their bodies started burning more of their own protein\u2014and that\u2019s exactly what happened. Switching to a ketogenic diet made them lose less fat mass and more fat-<\/span><i><span data-contrast=\"auto\">free<\/span><\/i><span data-contrast=\"auto\"> mass. Indeed, they lost more lean mass. That may help explain why the leg muscles of CrossFit trainees <\/span><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/29910305\/\" target=\"_blank\" rel=\"noopener\"><span data-contrast=\"none\">placed<\/span><\/a><span data-contrast=\"auto\"> on a ketogenic diet may shrink as much as 8 percent.
