The keto diet is very popular right now with many people, including celebrities, claiming to have had weight loss success by following it. This diet, which calls for low-carb and high-fat meals, might help one lose weight, but it's not necessarily recommended by doctors. In fact, many medical experts have some concerns about this diet because they worry that it prioritizes weight loss over good overall health, according to USA Today.
The way in which keto may help promote weight loss is through the sudden removal of carbs from the diet. Without carbs, the body goes into a state of ketosis when the body will burn fat for energy. The Paleo and Atkins diets are quite similar and have also led to weight loss success for some. But doctors worry that this diet will lead to a lack of consumption of other food items that are necessary to stay healthy. This could include fruits and vegetables.
Vasanti Malik, adjunct assistant professor of Nutrition at the Harvard T.H. Chan School of Public Health, explained his concerns regarding this diet.
"That's where I get a little concerned about the keto diet. You want to be mindful, because these foods – whole grains, fruits and vegetables – carry a number of beneficial nutrients – vitamins, polyphenols, fiber – that have been shown time and time again to be beneficial for cardiometabolic health."
