The carnivore diet, a no-carb, all-meat approach to eating, is gaining traction for weight loss and potential health benefits. However, cutting out entire food groups raises questions about its long-term health impacts. We consulted with a nutrition expert to explore the diet’s benefits, risks, and essential information.
How the Carnivore Diet Works
The carnivore diet is a very restrictive eating plan where only animal products—such as beef, pork, chicken, and fish—are consumed. Eggs and dairy are permitted, but only in small amounts. This diet excludes all fruits, vegetables, grains, legumes, nuts, and seeds, positioning it as a more extreme version of the keto diet.
The primary goal is weight loss by eliminating carbohydrates, forcing the body to burn fat for energy instead. Proponents believe this process can accelerate fat breakdown, improve blood sugar, and reduce inflammation.
Does It Help with Weight Loss?
While the carnivore diet may lead to initial weight loss, the long-term benefits and safety are less certain. The body may indeed burn fat for energy in the absence of carbs, but the health risks associated with such an extreme diet raise concerns.
Risks and Drawbacks of the Carnivore Diet
Here are five reasons to reconsider adopting the carnivore diet:
Nutritional Deficiencies
By eliminating plant-based foods, you miss out on vital nutrients like Vitamin C, potassium, magnesium, and fiber. These are essential for overall health, and their absence could lead to deficiencies over time.
Increased Risk of Heart Disease
A high intake of red meat can increase levels of ‘bad’ LDL cholesterol and blood lipids, both of which contribute to heart disease. This poses a significant health risk when following the carnivore diet.
Gut Health Issues
Without fiber from plant-based foods, the diet can cause constipation and disrupt the gut microbiome, which plays a critical role in digestion and immune function.
Kidney Stress
The body enters a state of ketosis on this diet, which can put undue stress on the kidneys and, in extreme cases, increase the risk of kidney stones.
Increased Risk of Colon Cancer
A diet rich in red and processed meats, combined with low fiber intake, has been linked to a higher risk of colon cancer.
A Balanced Approach to Nutrition
Experts advise against extreme diets that eliminate entire food groups. Shannon Haynes, RD, a registered dietitian, emphasizes focusing on balance rather than restriction. Instead of limiting your diet to one food group, try creating balanced meals with protein, carbohydrates, and vegetables. The MyPlate approach—where a quarter of the plate is protein, a quarter carbs, and half vegetables—offers a more sustainable and nutritious solution for long-term health.
While the carnivore diet may show short-term results, the long-term health risks and sustainability make it a questionable choice. For optimal health, a balanced, varied diet is the key.
