How the diets react
Diet Ratings
Zero net carbs, high in saturated fat and MCTs. Excellent cooking fat for keto. Sustainability concerns exist but nutritionally sound for ketosis.
Technically plant-based but raises significant environmental and ethical concerns within vegan community. Production drives deforestation and habitat destruction.
Some vegans accept palm oil as technically compliant, arguing that environmental concerns apply equally to other crops and that avoiding palm oil may not reduce overall harm.
Palm oil is technically unprocessed and paleo-compliant as a plant fat, but environmental and sustainability concerns dominate paleo discussions. Some paleo practitioners avoid it; others accept it as a legitimate alternative to seed oils. Refined versions should be avoided.
Strict paleo advocates (Cordain school) focus purely on nutritional compatibility and accept sustainably-sourced palm oil. However, many modern paleo practitioners (Sisson, Whole30 community) prioritize environmental ethics and recommend alternatives like coconut oil or grass-fed ghee.
Palm oil is high in saturated fat (50%), contradicting Mediterranean principles which emphasize unsaturated fats from olive oil. It is also highly processed and not part of traditional Mediterranean cuisine. Environmental concerns add to the recommendation against it.
Plant-derived oil from palm fruit. Violates carnivore exclusion of all plant foods and plant oils. While it contains saturated fat, the plant origin disqualifies it from carnivore diet.
Pure palm oil is a natural fat with no excluded ingredients. Compliant as a whole food fat source.
Pure oil with no fermentable carbohydrates. Monash University confirms oils are low-FODMAP at all reasonable serving sizes.
Tropical oil explicitly limited in DASH guidelines. High in saturated fat (>50%), raises LDL cholesterol. Contradicts core DASH principle of limiting saturated fat.
High in saturated fat (50%), pro-inflammatory profile. Dr. Sears emphasizes monounsaturated fats and avoiding saturated fat. Contradicts Zone anti-inflammatory foundation.
High in saturated fat and pro-inflammatory properties. Explicitly limited in anti-inflammatory guidelines. Also raises environmental and ethical concerns.
High in saturated fat (50%), which worsens GLP-1 side effects (nausea, bloating, reflux). Provides empty calories with no protein or fiber benefit. Difficult to digest in quantity. No nutritional advantage over unsaturated alternatives. Environmental concerns secondary to health impact.
