For those who are unfamiliar with keto, it's a low-carb, high-fat diet that sends your body into a state of ketosis. "In ketosis, the body is efficient at utilizing fat stores for energy," explains Serena Poon, CN, CHC, CHN, chef, nutritionist, Reiki master, and founder of the Culinary Alchemy program. "There is little research on the long-term effects of a keto diet in healthy adults. On the ketogenic diet, you are restricted from all grains, sugar, and high-starch and high-sugar vegetables and fruits such as potatoes, squash, dates, and bananas. Daily carbohydrate intake for a person on the keto diet is recommended to be 5% of total daily calorie intake."
While many people see dramatic results with keto, there are some watch-outs you'll want to be aware of. It limits starchy vegetables, whole grains, and legumes, which are high in fiber. Fiber can help with digestion and lower cholesterol levels. According to Harvard Health, some potential risks include nutrient deficiency, liver and kidney problems, constipation, fuzzy thinking, and mood swings. These are all things to think about and might be worth discussing with your healthcare provider to see if it's a good option for you.
Poon recommends working with a nutritionist to ensure that you're getting all the vitamins and minerals your body needs while on the keto diet. "Because vegetables often get overlooked on a keto diet, it is possible to become deficient in the abundant vitamins and minerals that you would receive from a diet that is rich in plant foods," she explains. "It would be possible to become deficient in folate, vitamin C, vitamin E, magnesium, and more. I recommend continuing to eat as many vegetables and fruits as you can fit into your low-carbohydrate diet to avoid these kinds of deficiencies."
