What is a ketogenic diet consist of?

A ketogenic diet, often referred to as keto, is a low-carbohydrate, high-fat diet designed to shift the body’s metabolism into a state of ketosis. In ketosis, the body primarily burns fat for fuel instead of carbohydrates. The typical macronutrient breakdown for a ketogenic diet is:

  1. High Fat: Approximately 70-75% of your daily caloric intake should come from healthy fats. Sources of healthy fats include avocados, nuts, seeds, olive oil, coconut oil, and fatty fish.
  2. Moderate Protein: Protein intake is moderate, making up around 20-25% of your daily caloric intake. Good sources of protein include meat, poultry, fish, eggs, and dairy products. It’s important not to overconsume protein, as excessive protein intake can potentially interfere with ketosis.
  3. Low Carbohydrates: Carbohydrates are restricted to a minimal amount, typically around 5-10% of your daily caloric intake. This translates to a very low carbohydrate intake, usually below 50 grams of net carbs per day. Foods high in carbohydrates, such as grains, sugar, and starchy vegetables, are limited.
