Keto diets are not only risky for kidney patients and pregnant women but also for others, too, as the diet increases LDL cholesterol levels and may also increase overall chronic disease risk.
Keto diets are not good for pregnant women and kidney disease patients, as the keto diet puts them at risk of adverse health effects, reveals a review in Frontiers in Nutrition. The review, Ketogenic Diets and Chronic Disease: Weighing the Benefits Against the Risks, also found that for most people, the possible long-term risks of the keto diet, including heart disease, cancer, diabetes, and Alzheimer's disease, outweigh its possible benefits.
‘Keto diets are not only risky for kidney patients and pregnant women but also for others, too, as the diet increases LDL cholesterol levels and may also increase overall chronic disease risk.’
“The typical keto diet is a disease-promoting disaster,” says lead review author Lee Crosby, RD, nutrition education program manager at Physicians Committee for Responsible Medicine. “Loading up on red meat, processed meat, and saturated fat and restricting carbohydrate-rich vegetables, fruits, legumes, and whole grains is a recipe for bad health.”Five key findings of the Frontiers in Nutrition review paper are:
- Keto diets may be especially unsafe for women who are pregnant or may become pregnant—low-carb diets are linked to a higher risk of neural tube defects in the baby, even when women take folic acid
- Higher-protein keto diets could hasten kidney failure in those with kidney disease
- Keto diets raise “bad cholesterol” levels for many patients
- Keto diets are presented as a panacea, but they are not likely to be safe long term
- Restricting carbohydrate skews the diet toward cancer-causing foods. In fact, typical keto foods have been linked to an increased risk of heart disease, cancer, diabetes, and Alzheimer's—often the very diseases they are touted to help
Keto diets have been promoted for weight loss and, less commonly, for other health reasons—seizure disorders, obesity and weight management, type 1 and type 2 diabetes, fatty liver disease, cancer, Alzheimer’s disease, heart disease, kidney health, and pre-pregnancy and pregnancy—all of which were considered in this review. It also looked at potential long-term effects on health.
“In addition to the significant risks to kidney disease patients and pregnant women, keto diets are risky for others, too, as these diets can increase LDL cholesterol levels and may increase overall chronic disease risk,” Crosby explains.
“While keto can reduce body weight short term, this approach is not more effective than other weight-loss diets.”
