A word of warning: be very wary of “keto” or “low carb” versions of cakes, cookies, chocolate bars, candies, ice cream, and other sweets. They will keep your cravings for a sugary taste, and can make you eat more than you need. They are oftan full of sugar alcohols – that can raise your blood sugar – and artificial sweeteners, whose health impacts are not yet known. Weight loss may also stall or slow. Learn more
Here's the reality: A high carb diet drives up blood sugar and insulin levels. All that sugar and insulin are inflammatory. The standard American diet offers lots of foods that are high sugar AND high in saturated fat, and in studies, these two factors were lumped together. So although saturated fat is healthy, it got the blame for the inflammation that causes heart disease because it was studied in combination with a high carb diet. A ketogenic diet plan which is high in saturated fat and very low in carbohydrate will REDUCE inflammation. (Reference here.)
It can be tricky calculating the precise kind of diet that leads to a long life. Part of the problem is that (thankfully) we don't live our lives in highly controlled laboratory conditions. Until that terrifying day arrives and we all become well-studied lab rats, we have to rely on long-term observational data, usually in the form of surveys, to know more about which diets are the best long-term plans.
In addition to burning fat reserves and super charging weight loss, ketosis produces a clean burning metabolic fuel that has many benefits. Ketones lower production of reactive oxygen species (ROS),1 enhance mitochondrial biogenesis,2 3 and induce positive epigenetic expression.4 Because of its neurological benefits, I went on a Keto Diet in 2014, and it has been helpful in moderating my MS symptoms.
The ketogenic diet is indicated as an adjunctive (additional) treatment in children and young people with drug-resistant epilepsy. It is approved by national clinical guidelines in Scotland, England and Wales and reimbursed by nearly all US insurance companies. Children with a focal lesion (a single point of brain abnormality causing the epilepsy) who would make suitable candidates for surgery are more likely to become seizure-free with surgery than with the ketogenic diet. About a third of epilepsy centres that offer the ketogenic diet also offer a dietary therapy to adults. Some clinicians consider the two less restrictive dietary variants—the low glycaemic index treatment and the modified Atkins diet—to be more appropriate for adolescents and adults. A liquid form of the ketogenic diet is particularly easy to prepare for, and well tolerated by, infants on formula and children who are tube-fed.
Achieving ketosis is a pretty straightforward, but it can seem complicated and confusing with all of the information out there.4If you want to learn more about ketosis and the scientific process around it, you can visit a very in-depth discussion about on Dr. Peter Attia’s website. Here’s the bottom line on what you need to do, ordered in levels of importance:
