Con: Vitamin and Mineral Deficiencies
Since the keto diet is so low in carbs, that means cutting out whole grains and fruit. Even though fruit has sugar in it, it's still an excellent source of fiber, vitamins, and minerals. And if you're more focused on eating fats and protein, you may neglect to eat the daily recommended amount of veggies and skip out on those important nutrients.
"You may end up with a diet that's deficient in some vitamins and minerals," Katherine Brooking MS, RD, cofounder of Appetite For Health, told POPSUGAR.
