Micronutrients & recovery
High-fat, low-carbohydrate (ketogenic) diets are nutritionally inadequate and require supplementation to meet micronutrient needs.
If you follow a high-fat, low-carb diet, you are likely missing essential vitamins and minerals found in fruits, vegetables, and grains. You should consult a healthcare provider about supplementation to ensure you are getting enough vitamins E, A, B-complex, calcium, magnesium, iron, potassium, and fiber.
ModerateSupportsMEDIUM confidence
High-fat, low-CHO diets are nutritionally inadequate. They are low in vitamins E, A, thiamin, B6, folate, calcium, magnesium, iron, potassium, and dietary fiber, and require supplementation.
