Keto Diet Popularity Wanes as Concerns Over Long-Term Health Emerge
The ketogenic diet, a high-fat, low-carbohydrate dietary approach, gained popularity in the early 2000s. However, a recent study published in the March 2024 issue of Current Problems in Cardiology has raised concerns about the diet’s effectiveness and long-term health implications.
The study, led by Joanna Popiolek-Kalisz, MD and PhD, examined several issues associated with the keto diet. Firstly, the study found that while the diet can lead to rapid weight loss, it is primarily due to water loss and does not result in sustainable, long-term weight management.
Furthermore, the study raised concerns about the diet’s impact on heart health. Adherents to the keto diet typically have higher levels of LDL cholesterol, which is associated with an increased risk of heart disease, blocked arteries, and mortality. This is primarily due to the diet’s emphasis on fat consumption.
Additionally, the keto diet has been linked to nutrient deficiencies, including essential vitamins and minerals. Conversely, it can lead to an excess of fat-soluble vitamin K, which can also pose health risks and increase the likelihood of kidney stones.
The study’s findings align with a recent decline in the popularity of the keto diet among Americans. According to the International Food Information Council’s annual study, the high-fat diet dropped in popularity by 4% in 2023 compared to the previous year. This downward trend is expected to continue as concerns over the diet’s long-term health effects grow.
In conclusion, the ketogenic diet has come under fire for its potential health risks and questionable effectiveness. While it may lead to short-term weight loss, it fails to provide sustainable results and may compromise heart health and nutrient levels. As a result, its popularity has declined, and it is recommended to consult with healthcare professionals before considering this or any restrictive dietary approach.
