What is the Carnivore Diet?
The carnivore diet focuses exclusively on animal products. Proponents believe that eating only meat, eggs, and animal fats can lead to health improvements like reduced inflammation and weight loss. Plant-based foods are completely eliminated. This often extends to most dairy products because of their lactose content.
The Role of Dairy on a Carnivore Diet
While the strictest carnivore diet forbids all dairy, many follow a more flexible approach, which may include low-lactose dairy products. The primary concerns with dairy are:
- Lactose Content: Lactose is a milk sugar, a carbohydrate. For a diet aiming for zero or near-zero carbs, this can be a problem. Lactose intolerance is also a concern.
- Additives: Many commercial dairy products contain additives or sugar, which strict followers aim to avoid. Products like skyr require closer inspection.
Is Skyr Carnivore-Approved?
Skyr, from Iceland, is high in protein and low in fat and carbohydrates. It's made by incubating skim milk with cultures, which ferments the lactose, reducing the lactose content. For those following a less-strict carnivore or ketogenic diet, this is a major plus.
Whether skyr is carnivore-approved depends entirely on the rules. If following a 'zero-carb' or 'lion diet,' skyr is not an option. It contains some residual lactose, and flavored versions contain sugar and other ingredients. If following a more flexible approach that includes dairy, plain, unsweetened skyr is a top choice.
Skyr Ingredients to Watch Out For
For carnivores considering skyr, read the label meticulously:
- Added Sugars: Many skyr products, particularly flavored ones, contain cane sugar or other sweeteners.
- Pectin and Thickeners: Some brands use plant-derived thickeners.
- Flavorings: 'Natural flavors' can be from non-animal sources.
- Plant-Based Options: Oat-based or other vegan 'skyr' alternatives are off-limits.
The Benefits and Drawbacks of Adding Skyr
Adding dairy to a carnivore diet has potential trade-offs.
Benefits
- Added Protein: Skyr is a protein source, helping meet daily needs.
- Probiotics: The live cultures in skyr can support gut health.
- Nutrients: Dairy provides a source of calcium.
- Flavor Variety: It provides a textural and flavor change.
Drawbacks
- Digestive Issues: Skyr can cause digestive problems, particularly for those with lactose intolerance.
- Dietary Purity: Including any non-meat product compromises the carnivore diet's definition.
- Potential Cravings: Including dairy can reintroduce cravings for sugar or carbs.
Skyr vs. Other Carnivore-Friendly Dairy
| Feature | Plain Skyr | Heavy Cream | Hard Cheese | Butter/Ghee | 
|---|---|---|---|---|
| Lactose Content | Very Low | Minimal | Very Low | Trace | 
| Carbohydrates | Low | Near Zero | Near Zero | Zero | 
| Protein | Very High | Low | Moderate | Zero | 
| Fat | Very Low | Very High | High | Very High | 
| Source | Cultured skim milk | Cream from milk | Aged milk curds | Churned cream | 
| Best for | High protein snack | Adding fat/calories | Flavor/calories | Cooking fat/flavor | 
How to Test Your Tolerance for Skyr
Start with a small amount of plain, unsweetened skyr. Monitor your body for digestive distress, bloating, or changes. If tolerated well, increase the amount. Remember that if the goal is strict adherence, even tolerated dairy is a departure from the core rules.
Conclusion
Whether skyr can be eaten on a carnivore diet is nuanced. While traditional, unflavored skyr is made from animal products and is low in carbohydrates, it is not considered acceptable by the most stringent carnivore followers. For a more flexible, 'meat-based' approach that includes low-lactose dairy, plain skyr can be a great source of protein and probiotics. The decision rests on health goals, digestive tolerance, and diet strictness. It is crucial to read labels to avoid added sugars and non-animal thickeners and to test personal tolerance before incorporating it fully.
A Final Word on Dairy Purity
For those concerned about the purity of their carnivore diet, focusing on whole, unprocessed meats, eggs, and water is the safest bet. However, the inclusion of carefully selected dairy, like plain skyr, can add variety and nutrients without derailing a low-carb strategy. As with any dietary modification, listen to your body and adjust as needed.
