    Frequently Asked QuestionsKeto Diet

    Will I lose weight on the keto diet?

    Probably, but it could come back if you stop doing keto (which is true of any diet, really). Diets don't require people to confront one of the main reasons they’re overweight in the first place: emotional eating. Learning to not reach for the cookies or chips when you’re stressed is tough, but once you flex those muscles, you have more freedom and control.

    Can the keto diet help my diabetes?

    Yes! Keto is a low-carb plan, which can help you lower your blood sugar levels. One study found that after six months on a keto diet, people were able to significantly cut back on their insulin medication. And any diet that helps you lose pounds is also good for diabetes, since being overweight is a major factor in the disease.

    Should I try keto if I have cancer?

    There isn’t enough research to know one way or the other. Some research shows that cancerous tumors feed on glucose, which could give keto an advantage over higher-carb plans; but for other cancers—namely breast cancer, prostate and colorectal cancer—high-saturated-fat diets may increase the risk. In addition, dietary elements of any new eating plan can interfere with or augment certain drug treatments. Always consult your doctor before you begin any “eat to beat” cancer regimen.

    What is dirty keto?

    This is basically the first phase of the Atkins plan, with any and all fat-laden fare on the menu—greasy ribs, steaks sautéed in butter, three-egg omelets topped with a mountain of cheese—without any attention paid to healthier fat sources or vegetables. Experts do not recommend this version of keto, obviously. Not only is it the antithesis of a well-balanced diet, but it’s way too easy to overdo it on calories, which defeats the whole purpose of a diet.
