A standard keto diet is a low-carb, moderate protein, high-fat diet that typically contains 70% fat, 20% protein, and 10% carbs. 

One of the goals of following a keto diet is to enter ketosis, a metabolic state where your body is using stored fat for energy instead of carbs. The body breaks down stored fat into molecules called ketone bodies, which are used as energy in the absence of circulating blood sugar from food.

While reducing carb intake so strictly can be challenging, the list of food items that fit the criteria of a keto diet is quite long. Here are the food categories and foods to eat anytime by Dr. Josh Axe.

What foods should I avoid on a keto diet?

A keto diet is different from regular, balanced eating recommendations. Many nutritious foods are sources of carbohydrates, including fruits, vegetables, whole grains, milk, and yogurt. 

On a keto diet, however, carbs from all sources are severely restricted to below 50 grams a day. People on the keto diet often eliminate bread, grains, or cereals from their diet and limit even most fruits and vegetables because of their carb content. 

For most people, the keto diet requires making significant changes to how they usually eat. The diet requires avoiding all carb-rich foods, including:

Any type of sugar: That includes white, brown, cane, raw, syrups, honey, agave, and anything containing fructose, glucose, maltose, dextrose, or lactose.

Any and all gains: That includes wheat, oats, rice, and all products containing corn, including popcorn, polenta, and cornmeal.

Most processed foods: That includes foods in the bag or box, canned food, crackers, chips, pretzels, candy, cookies, cakes, pies, ice cream, pancakes, waffles, oatmeal, cereal, granola bars, meal replacements, canned soups, and anything containing artificial sweeteners.

Sweetened and caloric beverages:  Soda, beer, wine, liquor, sweetened teas or sugary coffee drinks, fruit juices, milk, and dairy replacement beverages, like soy and Lactaid, are high in sugar and will disrupt your efforts to stay in ketosis.

Cow's milk and low-fat dairy: When you are on a strict ketogenic diet, you need to avoid cow's milk and low-fat dairy products.
