On average, people eat about half of their daily calories through carbohydrates. There are a few problems with this. First of all, when carbs are digested they cause an increase in blood sugar and insulin. Having high levels of insulin over time leads to insulin resistance, which can cause weight gain, prevents satiety, and leads to multiple diseases.
A ketogenic diet, on the other hand, is the ingestion of mostly fats, with a small to moderate amount of protein, and very little carbs. Usually a ketogenic diet will consist of about 5% of daily calories from carbs, 70-80% from fats, and 10-15% from protein.
Being in a state of ketosis, whether nutritional or fasting induced has a great number of very beneficial metabolic effects on the body. The ketogenic diet has been shown to help treat and/or prevent: cancer, diabetes (both types), insulin resistance, heart disease, neurological disorders (ALS, Parkinsons, MS, etc.), and acid reflux. Utilizing a ketogenic diet can also greatly affect weight loss and prevent aging on a cellular level.
In addition to the above health benefits, being in ketosis also helps with mental focus/clarity and increased energy.
