the Ketogenic Diet: Benefits, Risks, adn What Experts Say
the ketogenic diet, a high-fat, very low-carbohydrate eating plan, has surged in popularity, fueled by celebrity endorsements and promises of rapid weight loss. But is this dietary approach a sustainable path to wellness, or does it pose potential health risks? Here’s a comprehensive look at the science behind the keto diet, its potential benefits, and the cautions raised by nutrition experts.
As defined by Dr. Andreas Eenfeldt, the ketogenic diet is “a very low-carbohydrate, higher-fat diet, very similar to other low-carbohydrate diets.” The core principle involves drastically reducing carbohydrate intake while maintaining moderate protein consumption and increasing fat intake. This metabolic shift forces the body into a state called ketosis,where it begins to burn fat – both from dietary sources and stored reserves – for energy.
The diet recently gained renewed attention following reports that actress Halle Berry, age 59, incorporates the keto lifestyle into her routine, prioritizing the elimination of sugars and refined carbohydrates in favor of healthy fats like avocado and nuts, alongside vegetables and lean proteins. Juan Mielgo, academic secretary of the Spanish Nutrition Society (SEÑ), acknowledged the diet’s potential efficacy, noting its established role in specific medical contexts.
“In refractory epilepsy in children, its effectiveness has been demonstrated for decades,” Mielgo stated. “In adults, it can promote rapid weight loss and improve some metabolic parameters – insulin sensitivity, triglycerides, and glycemic control – in the short term.” However, he cautioned that many individuals experience challenges with long-term adherence, citing fatigue, constipation, and the diet’s inherently restrictive nature.
Beyond weight management, the keto diet’s potential benefits are being explored. Though, experts emphasize that it’s not a universally applicable solution. A senior official warned that inadequate planning can lead to nutritional deficiencies, including insufficient fiber, vitamins, and minerals. Furthermore, alterations in lipid profiles – specifically, increases in LDL cholesterol in some cases – and an elevated risk of kidney stones are potential concerns. “it is indeed not a worldwide strategy or risk-free,” the official emphasized. “Its submission must be individualized, with professional supervision and ensuring the quality of the food.”
The potential for serious health consequences underscores the importance of informed decision-making. One analyst noted the extreme risks associated with improper implementation, stating, “In extremes, the keto diet can lead to death due to kidney and liver failure. It is a warning to take into account.You have to be careful.”
In contrast to the restrictive nature of the keto diet, a more balanced approach to nutrition emphasizes whole, unprocessed foods. Nutritionist doctor and scientific communicator Francesco De Santis recently published Ricettario della Salute (The Recipe Book of Health), advocating for a dietary foundation built on fruits, vegetables, whole grains, legumes, nuts, and seeds. He highlighted the importance of incorporating quality proteins, such as fish and legumes, and prioritizing “good fats,” particularly extra virgin olive oil and oily fish. “Limiting simple sugars and ultra-processed foods is equally vital,” he commented.
Ultimately, the ketogenic diet presents a complex interplay of potential benefits and risks. while it may of
