Article: Foods allowed and not allowed on the Keto diet


The first doubt that assails anyone who decides to start in the world of the Keto diet is:

What can I eat and what can't?

In short, the ketogenic diet is a diet that limits carbohydrate intake; 5-10% of total daily calories are allowed to come from this macronutrient, which amounts to a total of between 20-30 g per day. As for protein, the percentage ranges between 15-25% and finally most of the caloric intake comes from fats, 65-75%, which allows our body to undergo the metabolic change called ketosis and use fat as fuel. .

Now, in practice, what foods can you consume?

First of all, a healthy keto diet will be based on natural, nutrient-rich foods . Let's start:


We start with FATS, the protagonists of the ketogenic diet. The first thing you should keep in mind is that these fats must be healthy, choose: extra virgin olive oil, virgin coconut oil, olives, avocados, homemade sauces such as mayonnaise or pesto sauce, also fat of animal origin and the dried fruits.

And discard trans fats, such as sunflower oil, palm oil, margarines...

The second most important macronutrient is PROTEIN and here the range of possibilities is enormous, from all types of meat: red meat, poultry, pork, organ meats, seafood, fish, especially blue, to eggs and dairy products, the latter in moderation its inflammatory effect.

The other great macronutrient is CARBOHYDRATES , and although their intake is very limited, vegetables are essential, chard, spinach, broccoli, zucchini, cabbages, cauliflower, lettuce, artichoke... Green has to be present. And the fruits ? The chosen ones will be wild fruits, raspberries, blackberries, blueberries... and others such as lemon or coconut.

Fermented foods are also great allies.


The large food groups that are not present in a ketogenic diet are: sugars of any type, cereals and pseudocereals and their respective flours, tubers and starches, legumes and certain vegetables with a high glycemic index.

Bread and sweets are two of the foods not allowed in the keto diet that are missed the most, and as we know, at Impossible Bakers we have made the impossible possible, creating keto breads and sweets made with natural ingredients of the best quality. .
