Keto is short for the ketogenic diet.
The ketogenic diet is essentially a very low carb, moderate protein, and high fat diet that allows the body to fuel itself without the use of glucose or high levels of carbohydrates. When the body is in short supply of glucose (which come from carbs), ketones are made in the liver from the breakdown of fats.
With careful tracking (I use MyFitnessPal), creative meals, and self control, this diet can lead to great weight loss, lower blood sugar, regulated insulin levels and less hunger and controlled cravings for sugars and carbs.
Before I started keto I was eating a very high carb diet: pizza, pasta, pastries, the works. Because of this, my body would take these carbs and turn them into glucose to power itself. Now that I’ve cut all that out, my metabolism uses up fat instead.
Typically a ketogenic diet restricts carbs between 0-50 grams per day. I started with a goal of under 20 carbs per day to help stick to healthier foods and reduce my cravings.
If you’re interested in going keto full-time, be sure to consult your doctor. I am not a medical professional, nor do I offer any medical advice.
