When you lose weight, fat cells shrink. In a fat cell, there are triglycerides and cholesterol. Now, as that fat cell shrinks, you can burn triglycerides, but you cannot burn cholesterol. So it will go into the blood, go to the liver, and come out through the bile. But you’ll be totally fine as long as your triglycerides are low. (If you’re not using those as fuel, then you’re eating too much sugar.)
All the bad hype you have been hearing about high-fat diets is not exactly true. If you personally read the studies involving high-fat diets, you’ll discover that 99% of it is a combination of high-fat and high-carbohydrate diets. When you combine high carbohydrates with fat or even protein, insulin will spike dramatically. So that deep-fried donut or deep-fried fatty fries are really fried carbohydrates.
The ketogenic diet reduces seizure frequency by more than 50% in half of the patients who try it and by more than 90% in a third of patients. Three-quarters of children who respond do so within two weeks, though experts recommend a trial of at least three months before assuming it has been ineffective. Children with refractory epilepsy are more likely to benefit from the ketogenic diet than from trying another anticonvulsant drug. There is some evidence that adolescents and adults may also benefit from the diet.
The types of nutrients you need for health are vitamins, minerals, trace minerals, proteins (amino acids) and healthy fats (fatty acids). Nutrients are the helpful substances that build body tissue and organs and allow all the chemical reactions to occur in the body. Your body requires certain amounts of nutrients, and those are called Recommended Daily Allowances (RDAs).
That's because my intro to this seemingly new plan was when I worked in a hospital, where ketogenic diets were specifically used as a medical nutrition therapy for pediatric patients with seizure disorders, for whom medication was no longer effective. In other words: It was used as an absolute last resort for families who felt otherwise hopeless in the face of a neurological disease, and under strict medical supervision.
There are so many tricks, shortcuts, and gimmicks out there on achieving optimal ketosis – I’d suggest you don’t bother with any of that. Optimal ketosis can be accomplished through dietary nutrition alone (aka just eating food). You shouldn’t need a magic pill to do it. Just stay strict, remain vigilant, and be focused on recording what you eat (to make sure your carb and protein intake are correct).
