Keto Diet: Research Finds Benefits and Risks
Low-Carb Diet Linked to Weight Loss but May Raise Cholesterol
The ketogenic diet, commonly known as the keto diet, is a high-fat, low-carbohydrate regimen that has gained popularity in recent years. Proponents of a ketogenic diet generally suggest limiting carbohydrates to 10% of total daily calories and protein to 20-30%.
A new study, published in the journal JAMA Internal Medicine, compared the effects of a keto diet and a diet low in added sugars. The study found that the keto diet was more effective for weight loss in the short term, but it may also increase cholesterol levels and reduce the body's ability to absorb certain nutrients.
Weight Loss Benefits
The research team found that those volunteers on the ketogenic diet had lost on average 16 kg of fat over the 12-week study period, compared to only 4 kg of weight loss in the group who followed the diet low in added sugars.
Cholesterol Concerns
However, the study also found that the ketogenic diet had several adverse effects. The most notable concern is that the diet raised levels of LDL cholesterol, the "bad" cholesterol, which can increase the risk of heart disease. The diet also decreased levels of HDL cholesterol, the "good" cholesterol, which protects against heart disease.
Nutrient Absorption
The keto diet may also impair the absorption of certain nutrients, such as calcium, iron, and zinc. This is because these nutrients are typically found in carbohydrate-rich foods.
Conclusion
While the ketogenic diet may be effective for weight loss in the short term, it is important to be aware of the potential risks, including increased cholesterol levels and impaired nutrient absorption. Individuals considering starting a ketogenic diet should consult with their healthcare provider to assess whether the diet is right for them.
