Foods not suitable for a keto or ketogenic diet

To achieve ketosis or formation of ketone bodies that is what is intended with the keto diet, it is essential minimize carbohydrate intake which constitutes the main energy fuel of our body.

Therefore, among prohibited foods on a keto diet The main sources of hydrates are found as follows:

Sugars and everything that includes it

Of course, one of the main sources of hydrates in the current diet are the sugarsTherefore, everything that includes them should be avoided in a keto diet.

From sugar as a sweetener to sugary drinks, fruit juices, goodies, buns, commercial ice cream, sauces, commercial snacks, cookies and the like are foods not fit for a keto diet and of course, unhealthy too.

Cereals and derivatives (including whole grains)

The grain They are one of the great sources of hydrates in our diet and are those that are recommended as a source of energy next to legumes. However, in the keto diet they are not allowed even in minimum quantities, we will even have to avoid whole grains.

Thus, no rice, oatmeal, breads, whole or refined flours, barley, rye or pseudocereals such as quinoa are admitted to the keto diet.

Due to the elimination of this large group of foods so popular in our diet, the keto diet is not easy to carry out.


Although they have many vegetable proteins and fiber, vegetables They are also a great source of hydrates. Thus, except the peanut which has very little amount of hydrates and rather provides protein and fat, the rest of the legumes are not admitted to the keto diet.

Of course, legume derivatives such as soy flour, textured soy or chickpea flour, or vegan "cheese" based on legumes neither are they accepted in the keto diet due to its rich in carbohydrates.

Fresh and dehydrated fruits

The fruits They are generally a good source of hydrates, especially natural sugars as well as other components that are beneficial to health. Therefore, they are not allowed in the keto diet.

Sometimes we can use a minimum of fresh tomato that is a fruit reduced in carbohydrates or, a little of a fruit rich in water such as lemon or lime. But in general they are not allowed in the keto diet excepting oily fruits very reduced in hydrates such as olives, capers or avocado.

Of course, dehydrated fruits that further concentrate their hydrates or sugars are not allowed at all in the keto diet.

Vegetables (especially starchy)

The vegetablesLike fruits, they are a source of carbohydrates of excellent quality. However, most of them exceed 5% of hydrates and therefore, are not allowed in the diet.

Ketosis can be maintained and therefore eventually allowed the intake of a minimum amount of zucchini, lettuce or eggplant which are vegetables rich in water and reduced in hydrates. However, in general, its presence in the usual diet should be avoided.

Alcoholic drinks

Because alcoholic beverages provide ethanol that is used as a priority as a source of energy, its intake hinders ketosis or what is the same, the burning of fats that is the ultimate goal of the keto diet.

Therefore, no alcoholic beverage inside is admitted to a ketogenic diet.

Milk, vegetable drinks or sugary yogurts

Believe it or not, milks and yogurts, even vegetables, can be very limited or banned completely in the keto diet. Especially sugary or flavored alternatives are not allowed which are the ones with the highest proportion of hydrates.

The Milk and yogurt without sugar and natural can be included in small proportions because they are also a source of natural sugars as is the case with fruits.

Therefore, the dairy that always predominates in keto diets is the cheese in all its variants.
