Experts question keto diet for long-term weight loss and health

The popular keto diet—which emphasizes eating minimal carbohydrates and high amounts of fat—has been shown to promote short-term weight loss, but some experts question whether it’s a good long-term option.

The diet’s restrictions on carbohydrates (5-10% of total daily calories, along with 70-80% from fat and 10-20% from protein) require limiting healthy foods such as whole grains, fruits, and some vegetables.
