The ketogenic diet gained widespread popularity in the early 2000s with its slogan “fat is not the enemy.” However, recent research highlighted in the March 2024 issue of Current Problems in Cardiology raises concerns about the diet’s long-term effects. The keto diet, which promotes high-fat, low-carbohydrate foods, may carry hidden risks.

Dr. Joanna Popiolek-Kalisz, MD, and PhD, led the study, pointing out several concerns about the keto diet’s structure. One of the primary issues involves weight loss. While people often experience rapid weight loss when starting the keto diet, this is likely due to water loss, not fat reduction. Dr. Popiolek-Kalisz notes that the ketogenic diet doesn’t meet the standards of a truly healthy diet. In fact, she argues that low-carb diets in general offer more heart-health benefits than the extreme low-carbohydrate focus of keto.

The study also highlights the potential heart-related dangers of the keto diet. Since the diet emphasizes fat intake, many followers see an increase in LDL cholesterol, which can raise the risk of heart disease, clogged arteries, and even early death.

Low-carb diets such as Atkins, paleo, and South Beach provide an alternative approach to weight loss while still focusing on heart health. Other studies have pointed out that the keto diet may cause vitamin and mineral deficiencies. Furthermore, the diet can lead to an excess of fat-soluble vitamins, particularly vitamin K, which is also harmful to heart health. Additionally, the risk of developing kidney stones is higher for those on the keto diet.

According to the International Food Information Council’s annual survey, more than half of Americans follow some type of diet or eating plan. However, the popularity of the high-fat keto diet dropped by 4% compared to the previous year. This decline in popularity is expected to continue as more studies highlight the potential risks associated with the keto diet.

In conclusion, while the keto diet may offer quick results in the short term, its long-term impact on heart health and overall well-being may not be as positive. People seeking sustainable weight loss and improved health might consider other low-carb diets that promote balance and avoid the risks linked to high-fat eating plans.
