Final answer:
The recommended fat intake for a ketogenic diet significantly exceeds the AMDR for fats and may lead to inadequate intake of fiber, vitamins, and minerals, which are abundant in carbohydrate-rich foods.
Step-by-step explanation:
The ketogenic diet's recommended fat intake of 55-60% is higher than the Acceptable Macronutrient Distribution Range (AMDR) for fat, which recommends 20-35% of daily calories from fat. The ketogenic recommendation contrasts with the general health guidelines and particularly with the American Heart Association's recommendation of keeping fat intake to 30% or less of daily calories, with less than 10% from saturated fats.
Following a ketogenic diet and the recommended amount of fat, a person may lack sufficient intake of other macronutrients such as carbohydrates and thus miss out on fiber, vitamins, and minerals that are predominantly found in high-carb foods like fruits, whole grains, and vegetables.
