The average dieter should comsume approximately 65 to 75 percent of their dietary intake in fat. The Keto diet is a high-fat diet. Its purpose is to create an increase in fat-burning ketones in the body.

The average dieter should limit their consumption of carbs to 10 percent of their intake. This is because carbs give the dieter energy in the form of glucose, which is not the aim of the diet. The high-fat intake replaces carbohydrates as the body's main source of fuel.

A dieter should consume about 15 to 25 percent of protein for their overall intake.

The keto dieter needs to restrict their consumption of carbohydrates drastically. As such, they should eat fruits and vegetables low in carbohydrates. A general rule of thumb is to eat vegetables that grow above ground, such as dark leafy greens, asparagus, and tomatos.

The dieter also needs to consume foods with a high fat content, such as:

• Butter, cream, cheese, high-fat dairy
• Meat, eggs, fish
• Coconut oil, olive oil, and other high-fat oils
• Nuts and seeds
• Leafy vegetables

The dieter should avoid foods high in carbohydrates. Eating high-carb foods prevents the body from reaching a state of "ketosis," necessary for weight-loss.

• Starchy vegetables such as potatos, carrots, turnips, and other tubers/roots
• Fruits and sugars
• Coconut oil, olive oil, and other high-fat oils
• Nuts and seeds
• Grains and other carbs; wheat, bread, pasta, rice
