The keto diet is a very low- or no-carb food plan that forces the body into a state of ketosis, which is when your body burns fat for energy instead of carbohydrates. Many keto diets limit the amount of food you should eat, like any other weight-loss plan, but with keto the type of food you can eat is just as important as the quantity. So what can you eat on the keto diet? Get ready to feast on fish, other seafood, low-carb vegetables forget potatoes or carrots, cheese, meat, poultry, eggs, plain yogurt, and of course fats. On a standard ketogenic diet, your calories should be made up of 75 percent fat, 20 percent protein, and 5 percent carbohydrate. This is unlike most typical American diets, and can be a hard adjustment for many people.
The high-fat, low-carb keto diet has been around for years as a therapeutic treatment for epileptic seizures, but it’s recently gained favor with celebrities and heath enthusiasts alike as a foolproof way to lose weight. It’s been tried by Hollywood stars including the Kardashians and Halle Berry, while Silicon Valley tech workers swear by its ability to lift their mental fog. Doctors are also starting to believe the plan holds promise for staving off diabetes. There’s even evidence to suggest it could one day help some drugs better combat cancer. Health experts are still cautious about recommending the plan across the board, however, not only because it’s difficult to follow but more importantly because there isn’t much long-term data about what it may do to heart health after years or decades of use. Cardiologists and kidney doctors are already expressing serious concerns about what they’re seeing in practice when certain patients go high-fat. The cardiologist Elizabeth Klodas says not all of her patients have done well on the trendy plan. Ethan Weiss, a cardiologist who himself has become an ardent follower of a high-fat keto diet plan, says that while high cholesterol isn’t a common issue with keto, it can happen. He sometimes suggests a high-fat keto plan to his patients working to manage diabetes, obesity, and other metabolic issues. But he’s cautious about how and when he prescribes it, recommending what he calls a “heart healthy” keto, with lots of fatty fish, olive oil, nuts, and avocado in the mix. Klodas said those were all healthful additions to any diet that she would endorse to her patients, too. Those appear to be anti-inflammatory — they help cholesterol.
I think that diet is important, and I have a personal interest in many of these approaches to nutrition, but what I share with patients is mostly my informed opinion based on as much science as possible. The main issue is that ketosis is arguably a backup mechanism for fuel and energy for the body, he says. Higher HDL cholesterol levels and lowering blood sugar are also associated with lower risk of heart disease. Still, there are potential downsides that patients need to watch out for, Chokshi says. Keto entails a significant portion of calories from fat, but not all fats are created equal. There is one recent long-term study suggesting a risk for heart disease. They found patients who followed a diet low in carbohydrates for nearly two decades had an increased risk for atrial fibrillation. But there are important caveats to consider. The researchers proposed that those at risk were probably eating fewer vegetables, fruits, and grains, which are known for being inflammation-fighting foods.
