CNN If you’re a fan of the “fat-burning” keto diet, you’ll be fired up about its ranking in the list of best diets from US News and World Report: It’s tied for last, along with the relatively unknown Dukan diet.

Summary: The keto diet is helpful for some medical conditions but potentially harmful for others, and it presents the risk of nutrient and fiber deficiencies. Like the Paleo Diet, the Keto Diet restricts grains, rice, and other high-carb foods. Two of them became pregnant during the study, despite previous infertility problems.
The keto diet has gotten a ton of attention—good and bad. Boosters say the high fat, very low carbohydrate diet nets serious weight loss. The modified keto diet may be the middle ground. Both the traditional and modified keto diets train the body to enter ketosis; when you severely limit carb intake, it starves the body of its main fuel source, glucose. That forces the liver to metabolize fat cells, turning them into ketone bodies, an alternative fuel source. People on the keto diet report losing weight, having more-consistent energy, and sleeping better. A traditional keto diet calls for up to 75 percent of calories to come from fat, 20 percent from protein, and 5 percent from healthy carbs—equal to about one cup of blueberries. In the modified plan, carbs tick to as much as 20 percent of your calories, fat goes to 50 percent, and the remainder is protein. For those looking to lose weight, aim to shed about a pound per week. Any more and you could be stealing from muscle mass—which is bound to happen on the traditional keto diet, Osborn says. Avoid it by easing into the diet.
A low-carb or keto diet can have many benefits, but not everyone needs to be on one. This guide presents some things to consider when choosing whether or not this kind of diet is right for you. Do you need low carb? Do you have health concerns that a low-carb or keto diet might help? Reducing carbohydrate intake — a little or a lot — can be an important first step in improving a number of health issues, especially obesity and metabolic issues. These health improvements can be achieved often by diet alone, without medications or other interventions that may have serious side effects. If you are already on medication — especially medications that lower blood sugar or blood pressure — or have other serious health concerns, you should seek the support of a healthcare provider when making any significant changes to your diet or lifestyle. Dietary changes can affect other aspects of your life besides health, such as athletic performance, hunger levels, and the time you spend cooking. Although these areas are seldom investigated in scientific trials, many individuals and clinicians learn about these effects when using a low-carb or keto diet for other reasons. Their experiences can help you make informed choices about these issues as well. Some people may not have reason to limit dietary carbohydrate, especially minimally processed carbs such as root vegetables, fruit, and legumes.
