How the diets react
Diet Ratings
1 medium orange (~154g) contains ~12g net carbs and ~9g sugar. High sugar content and carb density make it incompatible with ketosis maintenance.
Whole plant food, naturally vegan, excellent source of vitamin C. No animal-derived ingredients or processing.
Unprocessed whole fruit available to Paleolithic humans. Good source of vitamin C, fiber, and natural sugars. Whole fruit form preserves fiber and nutrients better than juice.
Oranges are whole fruits rich in vitamin C, fiber, and polyphenols. They are staple fruits in Mediterranean regions and encouraged for daily consumption as part of plant-based diet emphasis.
Plant-derived citrus fruit with high carbohydrate and sugar content. Completely incompatible with carnivore diet principles.
Whole fruit with no added ingredients. Explicitly compliant as a natural fruit allowed on Whole30.
Monash University rates oranges as low-FODMAP at a standard serving of 1 medium orange (150g). They are low in fructans and excess fructose relative to glucose.
Excellent DASH fruit. Rich in vitamin C, potassium, fiber, and folate. Low sodium. Whole fruit preferred over juice to maximize fiber intake.
Moderate-to-high glycemic load due to natural sugars and lower fiber-to-carb ratio than berries. Requires careful portioning. Dr. Sears recommends limiting to 1 serving per day maximum.
Good source of vitamin C, flavonoids, and hesperidin with anti-inflammatory properties. Supports immune function and reduces oxidative stress. Whole fruit preferred over juice.
Moderate fiber (2.4g per 100g), high water content (87%), vitamin C-rich, but contains natural sugars (9g per 100g) and lower fiber-to-sugar ratio than berries. Better as whole fruit than juice. Acceptable in moderation.
