If you are looking to lose weight, the ketogenic diet is an alternative with its risks and benefits, this low-carbohydrate diet and with a menu focused on the consumption of natural fats and proteins that help to reach the optimal state of ketosis, is presented as an alternative to others similar like the Atkins.

The amount of kilos that can be lost with the ketogenic diet depends on how overweight you are and following the plan to the letter so that the results are optimal.

But, contrary to what it may seem when looking at the list of allowed foods that are appetizing, it is a very hard weight loss plan because it is totally forbidden to try sugars and consume hydrated carbon, being important to drink a lot of water daily.

Description of the ketogenic diet

The ketogenic diet is a weight loss plan in which the proportion of carbohydrates is significantly reduced in order to promote fat oxidation that leads to the formation of ketone bodies. Thus, these compounds are used in an alternative way by the brain as a source of energy in the absence of glucose.

The proportion of carbohydrates in a ketogenic diet is usually well below the recommended total calories, and generally provides around 10% or less of the energy in the form of carbohydrates, there are different types of plans, including those that only allow fruits and vegetables in controlled amounts, while others completely eliminate carbohydrates.

There is also the ketogenic diet based on fasting as a vehicle to promote the formation of ketone bodies that must then be sustained to achieve weight loss at the expense of significant fat oxidation.

How to do the ketogenic diet

A term coined by Russell M. Wilder in 1921, the main objective of the ketogenic diet is to generate the formation of ketone bodies, therefore being a plan similar to that followed on a fast. This objective can be achieved through an insufficient intake of food or by a restriction of those that are rich in carbohydrates and are replaced by the consumption of foods rich in protein or fat.

The ketogenic diet, in all its variants , should only be carried out under medical supervision and for a limited time with menus that include a medium percentage of proteins combined with foods with natural fat (butter, coconut oil, olive oil, pork fat, cream) and a low level of carbohydrates.

Before talking about how the ketogenic diet is done, it is necessary to know how the combination of foods that make up each menu works and above all to understand that glucose, the simplest molecule to convert and use as energy, is always the one chosen by the body before the rest of the existing options.

By using glucose as the main source of energy, the body stores fat as a reserve and the more carbohydrates are consumed, the higher blood glucose rises. If more proteins and natural fats are consumed, the body adapts and changes its way of obtaining energy, instead of using glucose, it uses the body’s fat as a source of energy, generating weight loss.

To do a ketogenic diet it is necessary to plan the daily menu taking into account that most of the dishes should be composed of natural fats, proteins and a low amount of foods that provide carbohydrates. Between main meals and as a snack it is allowed to eat a little cheese or a handful of almonds.

It is important to remember that not all fats are the same. Thus, natural fats such as olive, coconut or avocado oil provide health benefits while the “trans fats” found in hamburger meat, margarine and all fried food, should be avoided as they are harmful. to health.

What to eat on the ketogenic diet

What is ketosis?

The body uses ingested carbohydrates to generate glucose for energy, and when not enough carbohydrates are consumed to meet the body’s daily glucose needs, the body will use stored fat to generate more glucose for energy.

In this way, the incomplete degradation of fatty acids will generate ketones in the body and this will lead to the desired state of ketosis. In short, in the absence of carbohydrate consumption, the body will begin to consume glucose and stored fat, causing weight to be lost gradually but constantly.

The 30-day ketogenic diet to lose weight is based on the principle that certain foods should not be combined, to get the body into ketosis and burn fat more quickly, it includes a list of allowed and prohibited foods that must be respected.

With the ketogenic diet, it is not necessary to worry about counting calories since fats and proteins have a great power of satiety for long periods of time, but for those who practice sports it is necessary to be alert because the burning of calories is greater and it is necessary eat enough to have energy.

With this list of foods it is possible to organize the weekly menu, keeping in mind that the 30-day ketogenic diet must be divided into stages.

First stage from day 1 to 10

  • Meats of all kinds and sausages (not in sandwiches, not with bread).
  • Fish (Preferably: salmon, tuna, cod, sardines).

Second stage from day 11 to day 20

To the foods allowed in the first stage are added:

  • ½ liter of low-fat milk.
  • Assorted raw or cooked vegetables.
  • Fruits limited to 2 oranges or 2 peaches or 1 apple or 6 plums or 1 cup of raspberries per day.

Third stage from day 21 to day 30

In this third and last stage, the following are added:

It is very common that, as with any diet to lose weight, a “plateau” period occurs, a period in which weight loss stops, there are numerous reasons for this to occur and in that case there are several methods that help to follow losing kilos such as varying eating patterns and eliminating certain foods that form habit.

Thus, for example, you can eliminate some dairy products, increase your fat intake a little more and reduce your carbohydrate intake to a minimum until you lose weight again.

How long does it take to get into ketosis?

Being restrictive, weight loss is always at the expense of the lack of supply of essential nutrients that the body needs for normal development, so it is always advisable to consult a doctor.
