Keto diets have become increasingly popular in recent years, with more and more Americans choosing to shun carbs in favor of other forms of fuel—but scientists warned on Sunday that the diet may come with some major downsides.
The diet deprives the body of carbohydrates in a bid to force it to burn fat for fuel, with 75% of calorie intake coming from fats. That means people following the keto diet eat foods like fatty fish, eggs, dairy, meat, butter and low-carb vegetables like asparagus and spinach.
