Is the Carnivore Diet right for you?

On Wednesday morning, amidst the blaring horns of Colombo traffic, there was a lot of commotion at my clinic. When I looked at the appointment list that day, I saw a new name – Ruwan. He was a young man, and at first glance, he seemed to be someone who was eager to go to the gym and get fit.

“Hello, dear Doctor,” Ruwan said to me as he came and sat down in his chair. “I’ve been hearing about the Carnivore Diet everywhere these days. So I wanted to try it too. It’s said to help you lose weight and get stronger. But I don’t know if there’s anything wrong with it. What does the doctor think?”

I smiled a little and said to him, “Ruwan, I’m so glad you’re here. The Carnivore Diet is a bit of an extreme diet. It has its good sides. But it’s important to know about it well before making such a big change. Let’s talk about it.”

What is the Carnivore Diet?

This diet only includes foods that come from animals, such as beef, pork, chicken, fish, and eggs . Nothing that comes from trees is allowed. That means no fruits, vegetables, grains, or nuts. It provides a significant amount of protein and fat . But it has zero carbohydrates.

“The plan for this diet is very simple,” I told Ruwan. “You only eat animal products. It’s like the other side of the ketogenic diet . There’s no room for vegetables or fruits.”

Nutritional composition of the Carnivore Diet

• Protein: So the main thing you get from this is protein. Meat, fish, and eggs provide all the amino acids the body needs.
• Fat: About 50-60% of calories come from fat. Animal fats, butter, and cheese provide the body with the energy it needs. Fat is also needed to absorb vitamins like A , D, E, and K.
• Carbohydrates: This doesn't even mention carbohydrates. They have a huge impact on the body's metabolism.

How does the Carnivore Diet affect the body?

Short-term effects:

“As soon as you start this diet, your body adjusts to a new state,” I told Ruwan. “This is called the 'keto flu.' It's not a good state.”

Keto Flu Symptoms:

• Tiredness
• Headache
• Digestive problems
• Memory loss
• Muscle pain
• Craving for food

“These symptoms can last for about a week or two. For some people, it can last longer,” I continued.

Long-term effects:

If you do this diet for a long time,

• Weight loss
• Stabilizing blood sugar levels
• Reduced inflammation
• Increased mental clarity
• Mood improvement

There are good aspects like. But,

• Nutritional deficiencies (especially fiber and vitamin C )
• Digestive problems ( constipation or diarrhea )

There are risks like.

Benefits of the Carnivore Diet:

• Weight control: High protein and fat content makes you feel full, which reduces calorie intake and leads to weight loss.
• Mental clarity: As blood sugar levels stabilize, brain function improves.
• Inflammation (reduction in inflammation): Some people find relief from autoimmune diseases and joint pain.
• Controls blood sugar levels: Helps control type 2 diabetes by reducing insulin levels.

Risks and controversies:

“While the Carnivore Diet has its advantages, there are also some differences of opinion,” I told Ruwan. “You also need to consider the risks.”

• Nutritional deficiencies:
  • Fiber (good for the intestines)
  • Vitamin C (important for immunity)
  • Magnesium and antioxidants
• Digestive problems:
  • Constipation can occur due to low fiber.
  • A sudden change in diet can cause diarrhea.
• Social and psychological impact:
  • It's getting difficult to go out to eat.
  • It becomes difficult to attend social events.

Frequently asked questions about the Carnivore Diet:

• Question: Will I get all the nutrients I need from this diet?
• Although animal foods provide important nutrients like B12 and iron, they can be deficient in things like fiber, vitamins C, and E. Eating things like liver and fatty fish can help a little, but you may need to take supplements.
• Question: Is this diet safe to do for a long time?
• This is still being researched. There may be risks such as heart disease, nutritional deficiencies, and digestive problems.
• Question: Will I lose weight if I do this diet?
• Many people lose weight because they eat fewer calories and feel fuller due to the protein and fat.
• Question: What do you do for the “keto flu”?

Important points:

• A carnivore diet involves eating only animal foods. Plant foods are not eaten.
• It can help you lose weight, increase mental focus, and reduce inflammation.
• There are risks like nutritional deficiencies, digestive problems, and social challenges.

I looked at Ruwan and smiled. “I can’t say this diet is good for everyone. If you want to try it, let’s work together and do it safely. Your health is the most important thing to me.”

He nodded and said, “Thank you very much, Dr. Priya. This has given me a lot of insight.”

When Ruwan left the clinic, I felt very happy. Because I gave him a good understanding of that diet. It was his decision. But now that he has a good understanding of it, he can choose the best thing for himself.
