Berg Nutritionals and Dr. In ketosis, glucose is not being used by the brain so it goes directly to your muscles.
Due to the minimal amount of carbs consumed, some of the protein you consume is converted to glycogen via gluconeogenesis. We will assume for the following discussion that liver glycogen has been depleted, ketosis established, and that the only source of glucose is from endogenous fuel stores i. The kidney also produces glucose as starvation proceeds. Note that athletes, even on a low carbohydrate diet, your body accumulates some glycogen from protein molecules, and they use it when they exercise and then rebuilt it the next day or two.
On test day, athletes ran for 3 hours. They then pieced everything together to better understand what each group was burning for fuel, and how hard they had to work. In one study, looking at well-trained cyclists, the rate of glycogen used by keto dieters was cut by a factor of 4. The study took bits of muscle out of their thigh muscles and measured muscle and measured glycogen before and after.
On the same duration of riding and the same intensity, their rate of glycogen use was one-fourth as much. Mike Davis — took a couple of racing sled dogs up in the Yukon and raced them miles a day for five days in a row. They did a half Iditarod distance, going around the same mile loop every day for five days in a row.
He fed the dogs a high fat, moderate protein, low carb diet. He measured muscle glycogen in the dogs before they started. At the end of five days, he did muscle biopsies on the dogs again. At the end of five days, they had more glycogen in their muscles than they did when they started.
Their muscle cells were sucking up every little bit of what they could find and putting it right back in the muscle as glycogen. And doing it much more efficiently than when they were fed a high carb diet. Rice, potatoes, sweet potatoes, pumpkin or other starchy vegetables are preferable — Proteoglycans are essential for forming cartilage and bone and are a combination of protein and glucose.
So starch and protein are essential for good bone formation. Remember to track everything!

Further, when you start fasting, your body goes into conservation mode, burning calories more slowly. Keep in mind that the initial weight lost on a fast is primarily fluid or "water weight," not fat. And when you go back to eating, any lost weight usually gets a return ticket back. Not only do most people regain weight lost on a fast, they tend to add a few extra pounds because a slower metabolism makes it easier to gain weight.
Worse, the weight that is regained is likely to be all fat -- lost muscle has to be added back at the gym. Side effects of fasting include dizziness , headaches , low blood sugar , muscle aches, weakness , and fatigue. Prolonged fasting can lead to anemia , a weakened immune system, liver and kidney problems, and irregular heartbeat.
Fasting can also result in vitamin and mineral deficiencies, muscle breakdown, and diarrhea. When you drink laxative concoctions during a fast, there is an increased risk of fluid imbalance and dehydration. The risks get more complicated and severe the longer you stay on a fast, or if you repeatedly go on fasts.
It sounds logical that fasting could cleanse your body of harmful substances that could cause a host of ailments like obesity , fatigue , and headaches. But there is no scientific evidence that you need to fast to "cleanse" your body or remove toxins.
Your body - specifically, the kidneys , liver , lungs , colon , and skin -- is perfectly capable of removing toxins itself. Nutrition experts agree that fasting is a potentially dangerous, and not particularly effective, way to lose weight. Instead of a fast, opt for a healthy eating plan that you can stick with long-term Healthy diets provide a minimum of 1, calories and include a variety of fruits, vegetables, whole grains, low-fat dairy, lean protein, and healthy fats , along with regular physical activity.
