metabolic state called ketosis, and starts burning its own fat for fuel,” says Lindsay Segal, a graduate student training to become a physician’s assistant. Granted, burning fat sounds like a good thing, but this is actually a dangerous state for the body to enter. We usually burn carbs for energy, which then fuels the brain, heart, and all those other necessary systems. But when our body is in this new mode, it produces substances called ketones, which can cause organs to fail and result in kidney stones and even kidney failure. According to the American Dietetic Association, ketones can dull the appetite, cause nausea, and even bad breath. Avoiding carbs—and the vitamins, minerals, and antioxidants you’d normally get from whole grains and fruit—means your body is missing out on a slew of cancer fighters. To avoid ketosis, add back at least 100 grams of carbohydrates every day.
