Low-carb diet for weight loss: what you need to know

The low-carbohydrate diet is a food trend based on the reduction of these types of nutrients to give preferences to proteins and fats. This trend has gained relevance in recent years due to the scientific support that accompanies it.

This diet will, in many cases, reduce body fat and weight. However, what makes it more interesting for us is the effect on our metabolism. In this article we will tell you what this feeding model consists of and we will give you some guidelines to follow it.


An article published in The New England Journal of Medicine indicates that a low-carbohydrate diet causes weight loss and improves health markers. Also, almost everyone knows someone who has tried it successfully. Let’s see in detail how it is done and who should avoid it.

What is a low carbohydrate diet?

A low-carbohydrate diet involves a higher ratio of fat and protein. It is also called the ketogenic diet.

For decades we have been told that fat is bad for your health. Meanwhile, low-fat, and often sugar-laden, “diet” products have flooded supermarket shelves. This was a serious mistake, which coincided with the onset of the obesity crisis.

How does the ketogenic diet work?

By avoiding sugar and starches, blood glucose stabilizes and insulin levels drop. This increases fat burning and helps you feel full, reducing food intake and causing weight loss.

Recommendations to follow this diet

Protein in a diet.
In a low-carbohydrate diet, other groups of nutrients predominate, such as proteins and fats. For this reason, it is also known as the ketogenic diet.

1. Don’t go hungry

One of the great advantages of a low-carbohydrate diet is that it regulates the glucose level, greatly spacing the feeling of hunger. Protein foods induce a higher level of satiety than those rich in sugars, according to a study published in 2015.

Eat when you are hungry, and eat well, until you can say, “I’m full and comfortable.” If at some point you have finished eating and you are a little hungry, eat a handful of nuts or a piece of avocado and you will see that you will not be hungry or small cravings in the middle of the morning.

2. Don’t sleep with the enemy

At home, avoid all types of forbidden carbohydrates and buy only what is necessary to follow a low-carbohydrate diet. In addition, you can color your fridge and pantry with fresh fruits, vegetables of all kinds and unprocessed meats.

3. Refresh and hydrate yourself well

Water is essential for our body and keeping the body hydrated has endless benefits. Also, you can choose to spice it up a bit with fruit, berry or herb peels. 

4. Eat eggs

During the diet you will think that there are not many things for breakfast but, it is the opposite! You can find many ways to eat eggs: poached, cooked, fried, scrambled with bacon, scrambled with vegetables, or as a French omelette.

Also, if you get hungry in the middle of the morning and you can’t stand it (which will happen at the beginning), you can have a boiled egg on hand, which is easy to transport and satisfying.

On the other hand, it is necessary to emphasize that the consumption of eggs does not affect cholesterol levels, as stated in a study published in the journal Nutrients.

Boiled eggs
Eggs are one of the best foods for a low carbohydrate diet. They are filling and there are many ways to prepare them.

5. Don’t be afraid of fat

Human beings have consumed fat throughout their history, for hundreds of thousands of years, because it is essential for survival and it is the macronutrient that contains the most energy per gram.
