Consuming an animal-based, low-carbohydrate diet was found to increase the risk of developing colon cancer, according to The Singapore Chinese Health Study. Low-carbohydrate diets that were centered around plant-based foods, however, did not have the same risk.1 Processed and red meat have been shown to increase the risk of colon cancer alongside other types of cancer.2

Most Comprehensive Review Yet of Keto Diets Finds Heart Risks, Cancer Risk, Dangers to Pregnant Women and Kidney Patients
Five key findings of the Frontiers in Nutrition review paper are: 1. 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. 2.Higher-protein keto diets could hasten kidney failure in those with kidney disease.
3. Keto diets raise “bad cholesterol” levels for many patients. 4.Keto diets are presented as a panacea, but they are not likely to be safe long term. 5. 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.

Ketogenic diets increase cholesterol and inflammatory markers associated with chronic disease, according to new research published in Obesity Biology and Integrated Physiology. Researchers monitored changes in lipids and inflammation during four weeks on a baseline diet (50 percent carbohydrate, 35 percent fat, and 15 percent protein) and four weeks on an isocaloric ketogenic diet (5 percent carbohydrate, 80 percent fat, 15 percent protein).Total cholesterol, LDL or “bad” cholesterol, ketones, and markers of inflammation increased significantly while on the ketogenic diet.
