Know what foods you’ll eat and avoid on the Ketogenic diet

You'll be drastically reducing carbs if you stick to a keto meal plan. Start with 20 to 30 grams of carbs per day, according to Kristen Mancinelli, RD, a dietitian in New York City and author of The Ketogenic Diet: A Scientifically Proven Approach to Fast, Healthy Weight Loss.

Make sure you know what foods are high in carbs, fat, and protein so you can make the right choices. Carbs are found in a variety of foods, including bread, spaghetti, chips, cookies, candy, and ice cream. Although beans are high in protein, they are also high in carbs. Carbs are rich in fruits and vegetables. Meat (protein) and pure fats, such as butter and oils, are the only foods that are carb-free (including olive oil and coconut oil).
