The carnivore diet includes:

• Red meat (beef, pork, lamb)
• Poultry (chicken, turkey)
• Fish and seafood
• Eggs
• Organ meats (liver, heart, kidneys)
• Some dairy products (butter, heavy cream)

Excluded foods:

• All fruits and vegetables
• Grains and legumes
• Nuts and seeds
• Plant-based oils
• Processed foods

The diet strictly avoids all plant-based foods, including those typically considered healthy. This makes it one of the most restrictive eating plans available.

Potential Health Benefits

Proponents of the carnivore diet claim several potential health benefits:

1. Weight loss
2. Improved mental clarity
3. Reduced inflammation
4. Better digestion
5. Increased energy levels

Some individuals report improvements in autoimmune conditions and mental health issues. The high protein content may support muscle growth and maintenance.

The diet’s simplicity can make meal planning and preparation easier for some people. It may also reduce cravings for sugary or processed foods.
