The ketogenic diet dates back to 100 years ago when it was first applied to children with difficult-to-control epilepsy. In fact, today it’s the main non-pharmacological option against this disease. However, it’s also become a trend as an ally for weight loss, as many celebrities have promoted it.

What does it consist of? The ketogenic diet is considered an unconventional diet, since the main source of energy is fat and protein instead of carbohydrates. For this reason, it’s sometimes tedious to plan your menus. Here’s an example for 7 days. Take note!

How does a ketogenic diet work?

To understand a little better what happens with the ketogenic diet – also known as keto diet – we must start with the fact that conventional diets use carbohydrates as the main source of energy. Meanwhile, in the ketogenic diet, these are reduced to a minimum of 50 to 60 grams per day, while fats are increased.

According to experts, this leads the body into a metabolic state, known as “ketosis.” Since energy can’t be processed from carbohydrates, it’s then forced to burn stored fats. In this process, ketones are generated, which are used as fuel – hence its effectiveness in weight loss.

That said, the keto diet prioritizes protein and fatty foods, such as the following:

  • Poultry
  • Fish
  • Seafood
  • Meats without visible fatty tissue

Now, with regard to fats, the key is to avoid hydrogenated fats and excess saturated fats. Instead, it’s better to choose polyunsaturated fats, such as those that provide omega 3, 6 and 9.

Similarly, it’s good to choose a minimum of vegetables and fruits with a low proportion of carbohydrates. Thus, your diet is enriched with dietary fiber and antioxidants.

Allowed and forbidden foods

When implementing the keto diet, it’s necessary to consider that some foods aren’t recommended, either because of their high carbohydrate content or because they are ultra-processed. In addition, saturated fat should be limited as much as possible. Let’s take a look at it in detail.

Permitted foods

  • Seed oils: These are abundant in polyunsaturated fats such as omega 6 and omega 3.
  • Butter: This is a dairy derivative that provides energy, medium-chain fatty acids, and vitamin A.
  • Oilseeds: These are a good source of essential fatty acids, such as linoleic and linolenic acid.
  • Red and white meats: It’s recommended to remove the external fat when consuming them.
  • Fish and seafood are a source of high-quality protein and omega 3 fat, related to brain and cardiovascular health.
  • Eggs provide protein of high biological value. In addition, they contain healthy fats such as omega 3, vitamin A and minerals.
  • Tofu, tempeh, and soy contain good quality vegetable protein. Soybeans are a source of linoleic and linolenic acid.
  • Green vegetables contain fiber, vitamins B2 and B1, and are a source of iron.
  • Red fruits and blueberries such as strawberries, blackberries, and raspberries. They contain anthocyanins with antioxidant properties and vitamin C.
  • Citrus fruits such as lemon, orange, tangerine and grapefruit. They’re a source of beta-carotene and vitamin C.
  • Dairy products such as yogurt, cheeses, and fermented kinds of milk (such as kefir). They’re high in calcium, phosphorus, and medium-chain fatty acids.
  • Cereals and whole-grain derivatives: Although they also provide starch, it’s preferable to select them for their fiber content.

Prohibited foods

  • Starchy vegetables: These contain high starch values, such as yams, cassava, sweet potatoes and tubers such as potatoes.
  • Cereals and refined derivatives: This is due to their high starch value. These include rice, corn, barley, oats, breads, cakes, pies, cookies, and pastries.
  • Sugar and sweet products: These significantly increase the carbohydrates that are restricted in the keto diet.
  • Ultra-processed foods: Many of these products are added starches and saturated fats.
  • Fruits high in sugars: This includes pineapple, banana, sapote, among others.
  • Sweet roots like beets and carrots. Sugars predominate in these roots.
  • Saturated fats like hydrogenated oils and the external fat of meat cuts. Margarines and butter also contain them.

Side effects and recommendations

To follow the ketogenic diet, it’s very important to maintain regular controls of ketogenic bodies in blood and urine. It’s also necessary to keep track of height and weight.

Initially, this type of diet can cause secondary symptoms similar to the flu. Some of the most frequent are the following:

  • Nausea
  • Digestive discomfort
  • Hunger
  • Decreased energy, mental capacity, and poor performance

The water and mineral balance of the body may also be modified. Therefore, it’s recommended to consume between 3000 and 4000 milligrams of sodium, 1000 milligrams of potassium and 300 milligrams of magnesium a day.

To begin with, it’s best to eat until you’re full. Do not restrict your calories too much. Because of this, it’s best to do so under the guidance of a nutritionist.
