Keto diet limits carbohydrates and promotes the consumption of fats. But Dr Shivam Joshi of NYC Health and Hospitals Bellevue said it wrongly restricts very important foods that previous studies linked to improved health.
“What people are doing is essentially throwing the baby out with the bathwater when they label all carbs as being bad,” Joshi, who is also a professor of medicine at New York University, told Business Insider. “That’s not true.”
Joshi is the co-author of an opinion piece posted in the medical journal JAMA Internal Medicine. He said scientific evidence may soon prove keto plan to be another diet fad.
The professor highlighted the involvement of ketones in weight loss. The liver releases these chemical compounds to help people convert fat into energy.
However, keto diet followers produce more ketones. High levels of the compounds may affect how the body processes good carbohydrates.
“Many people who buy into the keto diet say that carbs are bad,” Joshi said. “I’m not defending refined carbs. I’m defending your unrefined carbs, your fruits, your vegetables, your whole grains, beans, lentils, things like that. These are some of the most healthful foods on the planet.”
This is actually backed by science. Nutritionists have long been recommending adding more whole grains, such as brown rice, oats and barley, to diets because of their proven health benefits.
Diets with the said foods have been linked to longer life and lower risks of having serious health conditions or diseases. The U.S. Centers for Disease Control and Prevention previously reported consumption of whole grains could help people avoid cardiovascular disease, cancer and death.
Long term effects of keto diet
Despite being widely known, Joshi noted there are little efforts to explore keto diet will affect the body as a long-term diet. He said the people need to know the risks, benefits and alternatives of the approach.
“We don’t have long-term studies following a cohort of people for a long period of time documenting the safety,” he said.
