Diet Ratings
Butter contains 0g net carbs with 11g fat per tablespoon. Pure fat source, ideal for keto macronutrient targets and caloric density.
Dairy product made from animal milk fat. Explicitly excluded from vegan diet. No plant-based components.
Butter is clarified milk fat with minimal lactose and casein removed. Approved across paleo community as ancestral fat source. High in butyric acid and fat-soluble vitamins. Grassfed butter preferred.
Butter is high in saturated fat and contradicts the Mediterranean principle of using olive oil as the primary fat source. Minimal use in traditional Mediterranean cooking; olive oil is the preferred cooking fat.
Pure animal fat with negligible lactose and carbohydrates. Universally approved across all carnivore diet tiers including Lion Diet. Essential staple for cooking and nutrient density.
Butter is a dairy product and excluded from Whole30. The official program specifies ghee (clarified butter with milk solids removed) as the acceptable alternative.
Butter is low-FODMAP. It is primarily fat with negligible lactose and carbohydrates. Monash testing confirms low-FODMAP status at all practical serving sizes.
Pure saturated fat (7g per tablespoon) and cholesterol. DASH guidelines explicitly recommend limiting butter. No nutritional advantage over plant-based oils. Should be replaced with olive oil or other heart-healthy fats.
Nearly 100% saturated fat with no protein or carbs. Directly contradicts Zone's anti-inflammatory fat preference for monounsaturated sources. Ghee or olive oil strongly preferred. Sears explicitly recommends avoiding butter in favor of healthier fat sources.
High saturated fat and arachidonic acid. No significant anti-inflammatory compounds. Weil's pyramid recommends extra virgin olive oil instead. Butter should be minimized in anti-inflammatory diet.
Pure saturated fat (11g per tbsp), zero protein, zero fiber. Extremely high calorie density (100 cal per tbsp). Directly worsens nausea, bloating, reflux, and GI distress in GLP-1 patients. No nutritional benefit for GLP-1 diet. Should be avoided entirely.
