The ketogenic diet is gaining popularity in the media. As a nutrition educator the most common question that I’m asked among medical students, residents and the media is, “should I follow the ketogentic diet?” Checkout my video below, and the recap is outlined with 5 main takeaways (and references too).
We don’t have enough information to establish this diet as a widely applied evidence based method. The Academy of Nutrition and Dietetics doesn't yet recommend or advise this diet to be used for the masses, or general populations. With this diet folks are consuming up to 40% percent of calories from fats. Some research does show this diet can be an effective method in the short term, but we need more research to show long term effects.
The diet isn't new, but some evidence does show that this approach is used to control pediatric epilepsy. More research is needed for adults and disease stages such as diabetes.
3. Science of the diet:
the ketogentic diet forces the body to metabolize fat, it puts the body in a starvation stage by using fat as the primary fuel (~40% of macro-nutrient profile) instead of the preferred method which is carbohydrates. Keto dieters throw their body into ketosis with the macro-nutrient ratio and favorability to fat. If a ketogentic dieter “slips up” they can easily throw their bodies out of ketosis which negates the "diet" entirely. Research shows that we might need blood studies or an EKG to monitor our heart when following this strict diet plan.
4. Different types and ranges within the “ketogenic diet” plan:
- MCT oil
- Low glycemic diet
- Modified atkins
5. Final takeaways-- and, would I try this dietary pattern?
With close medical supervision some folks have shown to benefit from this dietary pattern in the short term. Following this diet is difficult. I would not “try” the ketogenic diet because a. I'm skeptical of the safety and b. I subscript to the plant based approach which favors a higher percentage of carbohydrate intakes. The Academy of Nutrition and Dietetics and 2015-2020 American Dietary Guidelines back up three dietary patterns: Mediterranean, plant based and modified DASH. More on that coming up.
