Negative effects of a ketogenic diet, according to a DR

Even though the Mediterranean diet is back in the limelight, many people are part of the Keto team. The low carbohydrate and high fat ketogenic diet was the The hippest food plan of 2018, with enthusiastic advocates about the weight loss they've suffered, the decrease in sugar cravings and even the decrease in anxiety. Even brands have spread to the market with "keto-compatible" products that make it easier to keep the diet.

Registered dietitian Brigitte Zeitlin, MPH, RD, owner of BZ Nutrition is not one of the legions of keto fans. "The keto diet was created by doctors to help treat children with seizure disorders, such as epilepsy, in whom medications were no longer working and who were monitored under medical supervision," she says. "This diet was not meant for generally healthy people and was not meant for weight loss. The fact that children are under medical supervision is a pretty good indicator that this diet was not created for the general public to adapt. In fact, I was really surprised to see that this form of medical nutritional therapy has become the latest in fashionable diet. "

Yet we are all here. While many say that the keto diet has been beneficial for them, Zietlin fears that anyone will linger in the long run. Unlike the Mediterranean diet, for example, the ketogenic diet is so new (at least in terms of how people use it in adulthood) that scientists have not been able to study the effects. to maintain it longer. of time. (FWIW, not all experts are keto-friendly for more than a few months.)

The research that exists is a mixed bag. In 2018, two studies comparing the effects of a low-carb diet and a low-fat diet had conflicting results: one found that it was not the only way to go to work. There was no significant difference in terms of weight loss between the two diets over a 12-month period, the other -carb was better for losing weight. A study in 2019 found that people who followed a high-fat diet for six months experienced "adverse changes" in their gut microbiome, which could have more significant health consequences. But again, long-term research is just not there. It may be harmless or even good, but as Zietlin points out, we do not know yet.

Another reason why Zeitlin is not a keto adept is its anti-carb appearance. "I am 1000 percent for carbohydrates, "she says. (For the record, she is not the only RD who thinks this.) "Carbohydrates include all vegetables, fruits and grains. So with keto, when they restrict your carbs, that means they're restricting your vegetables, "she says. "When did you ever hear of a" healthy "diet that tells you to eat less the vegetables? If you are discussing trying the keto diet, this should be a red flag for you. In addition, she states that a severe restriction of your carbohydrate intake means the loss of many sources of fiber, which could cause constipation. Not funny.

That said, if you are currently practicing the keto and it works for you, Zietlin does not want to discredit that. "If you do keto and feel good, keep it up," she says. "If you get the results you want, if you feel good and if you have normal bowl movements without coffee, then fantastic – seriously, you've found something that works for you. As a health professional, part of my job is to weigh the pros and cons of any plan of life and determine if it is a good choice for most people at the universal level. And the keto diet is just not that. »Cue mic drop.
