You have about 160,000 Kcals of fat available to burn – producing your own glucose in the process when needed (for anaerobic bursts). In contrast you only store around 400 to 500 Kcals of glucose/glycogen ready for use so if you are not adapted to burning fat then you are physically dependent and addicted to eating carbs. When you hear of a runner “hitting the wall” it’s only because of their unnatural carb addiction – an efficient fat burning athlete can run all day and will never have this problem. The human body is specifically designed to run long distance and can outrun almost every other animal on this planet – we can even run though intense heat because we sweat.
If you have health reasons that make you want to try it and eating bacon, eggs and steak salads every day sounds amazing, maybe you could swing it. If nothing makes you happier than a fresh piece of sourdough, or if beans are one of the protein sources you rely on, there’s no point in trying a diet that’s not going to work. (And, by the way, sourdough toast with mashed avocado for breakfast and black bean soup for lunch are really delicious and healthy.)
Conklin's fasting therapy was adopted by neurologists in mainstream practice. In 1916, a Dr McMurray wrote to the New York Medical Journal claiming to have successfully treated epilepsy patients with a fast, followed by a starch- and sugar-free diet, since 1912. In 1921, prominent endocrinologist Henry Rawle Geyelin reported his experiences to the American Medical Association convention. He had seen Conklin's success first-hand and had attempted to reproduce the results in 36 of his own patients. He achieved similar results despite only having studied the patients for a short time. Further studies in the 1920s indicated that seizures generally returned after the fast. Charles P. Howland, the parent of one of Conklin's successful patients and a wealthy New York corporate lawyer, gave his brother John Elias Howland a gift of $5,000 to study "the ketosis of starvation". As professor of paediatrics at Johns Hopkins Hospital, John E. Howland used the money to fund research undertaken by neurologist Stanley Cobb and his assistant William G. Lennox.
When carbohydrates are used by the body as an energy source, the blood sugar levels become unstable. As the energy source is not consistent it is difficult for your brain to stay focused for long periods of time. On the other hand, when you are in ketosis and the brain uses ketones as a fuel source, which has a consistent fuel source and you can focus for longer periods of time. Hence, you also tend to feel more active and alert.
I am sorry you had this experience. I feel that this educator was not giving you good advice. All my women who want to lose weight are recommended to consume 30 grams of good carbohydrates at each meal, and 15 at each snack. If you were not trying to lose weight, I would have recommended 45. I find this is all it usually takes to begin to lose some weight as you start to get active. Patients set their own goals with motivational help from their Certified Diabetes Educator. Our intent is never to insult, and you should not have gone through that. It sounds that you have now found the right path. There are many CDEs who could help you, so see what tools and motivation others may offer. I wouldn’t let one bad apple spoil the whole bunch. Many CDEs are also diabetic.
This diet also works for every type of eater who wants variety in their meals. I don’t know about you, but I’ve never had Pistachio-Crusted Sole much less would I know how to make it. But in the “Mediterranean Diet Plan,” everything I need to know is on page 175 along with substitution tips in case I can’t find pistachios or want to try pecans or cashews instead. I also can see the health breakdown too. “The Mediterranean diet incorporates as lot of nuts, like walnuts, pistachios, and cashews which have a lot of fiber,” adds Zogheib. “Also tuna fish, king mackerel, salmon, all have omega 3 and omega 6 fatty acids. There’s are whole grains, bananas, and one of the best oils to bake with — canola and olive oils. You can replace fatty butter with these oils when baking.”
Reduced hunger. Many people experience a marked reduction in hunger on a keto diet. This may be caused by an increased ability of the body to be fueled by its fat stores. Many people feel great when they eat just once or twice a day, and may automatically end up doing a form of intermittent fasting. This saves time and money, while also speeding up weight loss.
