Is the Carnivore Diet right for you?

On a Wednesday morning, amidst the honking of horns and the traffic jams on the streets of Colombo, there was a greater commotion than usual at our clinic that day. That day, as I was looking at the list of patients, I saw a new name - Ruwan. He was a young man who was keen to exercise and shape his body.

"Hello, Doctor Priya," Ruwan began as he came and sat down in the chair in front of me. "I've been reading a lot about the Carnivore Diet online these days. Everyone says it helps you lose weight quickly and gives you a lot of energy. I've been wanting to try it too. But I came to find out if there are any health risks involved."

I looked at Ruwan and said in a friendly tone, "Ruwan, it's really valuable that you came to discuss this. Because the Carnivore Diet is not a normal diet, but a very extreme diet. It has many benefits as well as significant risks. So today, let's talk about what this Carnivore Diet is and how it affects our bodies."

What is the Carnivore Diet?

The Carnivore Diet is a 100% animal-based diet, meaning you only eat animal products like beef, pork, chicken, lamb, meat, fish, eggs, and butter or cheese.

It completely prohibits the consumption of any plant-based foods - vegetables, fruits, grains (rice, bread), nuts or seeds. This is a diet that is very high in protein and fat, but 0% carbohydrates. "Ruwan, to put it simply, this is the Keto Diet taken to the next level," I explained.

Nutritional composition of the Carnivore Diet

• Protein: Meat, fish, and eggs provide the body with all the amino acids necessary for muscle growth.
• Fat: Animal fat provides between 50% and 60% of the body's calories. Fat helps the body absorb fat-soluble vitamins such as vitamins A, D, E, and K.
• Carbohydrates: Since carbohydrates are not available at all, the body's metabolism takes a completely different path.

🚨 Red Flags that require immediate medical attention

If you experience any of the following dangerous symptoms while following the Carnivore Diet, you should stop the diet immediately and seek medical attention:

• Chest pain or palpitations: Consuming too much saturated fat can cause cholesterol levels to rise rapidly and increase the risk of heart attack.
• Severe dizziness or fainting: Low blood pressure caused by a rapid drop in sodium and water levels in the body (dehydration).
• Severe pain and swelling in the joints: Gout is a condition caused by an increase in uric acid in the blood due to excessive meat consumption.
• Severe diarrhea or stomach cramps that last for several days.

Short-term and long-term effects

1. Short-term effects (Keto Flu)

During the first 1-2 weeks of starting the diet, you may experience an uncomfortable condition called Keto Flu as your body adjusts from burning carbohydrates to burning fat. Here are its symptoms:

• Frequent severe fatigue and headaches.
• Difficulty concentrating (Brain Fog) and memory loss.
• Constipation or diarrhea caused by changes in bowel function.
• Muscle pain and cramps.

2. Long-term advantages and disadvantages

Benefits:

• Weight control: Being rich in protein and fat, it keeps you full for longer, which reduces food intake and leads to weight loss.
• Blood sugar control: Insulin levels remain stable since there are no carbohydrates.
• Reduced Inflammation: Joint pain and skin conditions may be temporarily reduced in some people.

Disadvantages and Risks:

• Nutritional deficiencies: The body lacks essential nutrients such as fiber, vitamin C, and magnesium.
• Heart disease risk: High animal fat increases the risk of blood vessel blockage.
• Social challenges: Face severe discomfort when eating at outdoor events or hotels.
