What is the Ketogenic Diet?
The Ketogenic or Keto diet for short is a buzzword now, but it’s not new! Decades ago, it was used primarily to treat epilepsy in children whose seizures were uncontrolled. Research found that those with epilepsy had fewer seizures when in a state of ketosis vs. being glucose dependent. Today, there are many more applications for this diet that show promise to continue researching for more potential benefits. But, let’s take a deeper dive into what being in ketosis really means!
Being in ketosis means that the primary fuel source in the diet is fat, instead of carbohydrates. When you become fat adapted and burn fat over glucose, the body makes byproducts called ketones which the brain used for fuel. This spares glucose, the primary fuel source for the red blood cells, endocrine system and muscles. Traditionally, carbs make up 45-65% of our daily intake, protein makes up 10-35% and fat makes up 20-35%. On the keto diet, one might be consuming as much as 70% fat, 20% protein with a mere 10% coming from carbohydrates. One a standard 2,000 calorie diet that is only 50 grams coming from carbohydrates. A very strict approach to this diet might allow only 20 grams of carbohydrates, while a more moderate approach may allow between 40-60 grams depending on goals and taking into account each individuals therapeutic need.
So, what are some reasons to pursue a very low carbohydrate diet like this? Evidence is suggesting that the ketogenic diet is a great way to spark weight loss. Since it’s very low carbohydrate, this keeps insulin (our fat storage hormone) low. This means that fat stores can be unlocked and used for fuel. Additionally, prevention and improvement of neurodegenerative diseases like Alzheimer’s and Parkinson’s Disease have been seen with high fat diets. The brain seems to do very well when using ketones for fuel instead of glucose. These applications are very relevant for Americans today, as neurodegenerative diseases and obesity are on the rise. Maybe even more important, are the applications for cancer. Cancer cells love sugar (glucose). Starving the cancer cells on a ketogenic diet shows promise in slowing cancer progression.
One drawback to the keto diet is that it is usually low in fiber since fiber is found in carbohydrate rich foods. GI issues like constipation, cramping or acid reflux may occur. One way around this is to count only net carbohydrates. That is, total carbohydrates minus the total fiber. This is usually a more moderate approach, but still confers the benefits of a traditional diet and keeps carbohydrate intake low.
The long term effects of the ketogenic diet are still being studied, but it shows much promise for short term use. Pregnant or nursing women, those with gallbladder disease or insulin dependent diabetics should use caution and discuss with their health care or dietary professional before implementing and keto changes into their diet.
If you want to learn more about this diet, book an appointment with Liz or check out “The Keto Diet”, a great comprehensive read on those curious about whether a high fat diet might be right for them. Remember that every body is different and diets should be tailored to what works best for your health and wellness goals.
Here is an example of the satiating kinds of meal plan a person can enjoy on the Keto Diet!
For breakfast you might have scrambled eggs and add in heavy cream, chives, and up to 4 slices of your favorite nitrate free bacon. With so much dense nourishment, you will hardly notice that you skipped the bread!
For lunch, put your favorite protein on a bed of baby salad greens, add a vinegar or cream based dressing.
For dinner: Go all out with a generously cut Ribeye that can be enjoyed with mushroom cream sauce and several ounces of broccoli.
