A basic keto meal plan should consist of 75% fat. Protein can be around 20 to 25%, while net carbs should be 5% at most. A sample menu can include two scrambled eggs in the morning with black coffee, a bun-less, sauce-less burger for lunch and chicken breast and sautéed greens for dinner. You can drink milk as long as you limit your carb intake. Plain black coffee and water are also preferred over sodas.
