What is this high-protein, low-carb diet?

Simply put, this involves adding more protein-rich foods (such as fish, meat, and eggs ) to our daily meals, while limiting foods high in carbohydrates, such as rice, bread, grains , and potatoes.

Many people turn to this type of diet to lose weight. However, some also follow this method to control blood sugar levels and conditions such as diabetes and prediabetes.

This method began to become popular in the world around the 1970s, especially with the (Atkins Diet ). Then came various methods like (Paleo Diet), (South Beach Diet) and the most well-known ( Keto Diet ). In all of these, it is generally said that between 30% and 50% of the total calories consumed per day should be obtained from protein.

But remember, before starting any diet, especially if you have other medical conditions, it is very important to talk to your doctor and seek advice.

How does this eating pattern work inside the body?

The main source of energy for our bodies is carbohydrates, which are starches. When we limit things like rice and bread, our bodies don't have enough carbohydrates to provide energy.

What happens then? Our bodies are very smart. They look for another way to get energy. That is to start burning the fat stored in the body and create energy. When fat is burned in this way, something called ketones is formed. After that, these ketones become the main source of energy for the body. This state is called ketosis in medicine.

This method works as follows:

  • Weight starts to decrease as the body burns fat.
  • Eating more protein reduces hunger and makes you feel full . This also controls frequent eating.
  • Getting enough protein also helps with muscle growth .

What should you do if you are starting this type of diet?

The first thing to say is, before starting this , meet with your doctor and discuss your health condition. It is essential to know if this is compatible with any other medical conditions you may have.

Then think about these things:

  • Prepare the necessary things at home: Bring and keep high-protein, low-carb vegetables and meats like fish, chicken, eggs, cheese, broccoli, spinach, and cauliflower.
  • Think about snacks: Many of the snacks we eat on a regular basis are high in carbohydrates. So, pack protein-rich snacks like a piece of cheese, a boiled egg, or Greek yogurt.
  • Drink plenty of water: When we reduce our fruit intake, the amount of water our body receives may also decrease. So remember to drink plenty of water throughout the day.
  • Set goals: Don't try to change everything all at once. Make small changes and set realistic goals that you can keep working towards.

What can you eat and what should you limit?

To get a clear idea about this, see the table below.

Type of food Examples (good things to eat more of)
Meat and fish Chicken, beef, fish (especially heart-healthy fish like salmon, mackerel, herring, and sardines), eggs.
Vegetables (low in carbohydrates) Broccoli, spinach, kale, cabbage, cucumber, cauliflower.
Dairy foods and others Cheese, Greek yogurt, tofu.
Nuts and oils Avocado, olive oil, nuts like cashews, almonds (in limited quantities).
Fruit (low carb) Fruits like raspberries and blackberries in very small quantities.
Things to limit or stop Rice, bread, noodles, potatoes, sweet potatoes, grains, sugar and sweetened beverages, fruits high in sugar (such as mangoes, bananas).

What are the benefits and risks of this diet?

Like anything, this method has its pros and cons. It's important to be aware of both.

Pros Risks and Cons
Weight loss: Protein helps you feel full for longer, reducing your desire to eat unnecessarily. In the early stages, reducing carbohydrates can also help you lose weight by removing water from your body. High cholesterol: Eating too much of fatty meats and full-fat dairy products can increase bad cholesterol levels and increase the risk of heart disease.
Blood Sugar Control: Being low in carbohydrates, it helps control blood sugar levels in diabetes and pre-diabetes. Effects on the kidneys: If someone who already has kidney disease consumes too much protein, it can put an extra burden on the kidneys and worsen their function.
Strengthening muscles: Some diets cause muscle loss along with weight loss. However, this method helps maintain muscle strength because it provides a good amount of protein. Nutritional deficiencies: When you limit fruits, vegetables, and grains that contain carbohydrates, you may not get the vitamins, minerals, and fiber your body needs.
Kidney stones and bone weakness: Too much protein can cause excess calcium to be excreted in the urine. According to some studies, this may increase the risk of kidney stones and bone weakness (osteoporosis).

Who should not follow this diet?

This diet is not suitable for people with certain health conditions. If you have any of these, don't even think about it.

  • People with kidney disease or kidney-related problems .
  • Pregnant or breastfeeding mothers. Balanced nutrition is essential for both mother and child during this time.
  • People who have problems with constipation . This condition can be worsened by a decrease in fiber-rich foods.
  • People who have or have had eating disorders , thinking abnormally about food.

Ultimately, the best person to decide whether this is right for you is your doctor. Talk to him or a nutritionist and come up with a plan that will ensure your body gets all the nutrients it needs.

Remember, truly successful weight loss is not about a temporary diet, but about adopting a healthy lifestyle that you can maintain for the rest of your life.
