There are many myths about low carb diets. Perhaps the most common myth is one perpetuated by people in the medical profession who don’t understand nutritional ketosis, confusing it with ketoacidosis. When low carbohydrate, high fat diets induce the body to shift to ketones in place of glucose for normal metabolism, ketones become significantly elevated in the transition period, then stay slightly elevated thereafter. Ketoacidosis is an extreme pathological complication of diabetes in which ketones become very elevated, with serious potential health consequences. Here’s a chart from Jeff Volek and Steve Phinney’s Art and Science of Low Carbohydrate Performance showing typical levels in the various possible states.
