According to a study published in the Journal Cell Metabolism, the keto diet consisting of high-fat, low-carb food can help to fight against cancer. Researchers noted that the keto diet could help prevent various cancers by starving the tumors of the glucose needed for their growth. 

In the study, test subjects with pancreatic and colorectal cancer showed that the keto diet led to the accumulation of toxic lipid byproducts in the body and killed the cancer cells by ferroptosis. Although this slowed the growth of tumors, it caused the early onset of a lethal wasting disease – cachexia.

Patients with cachexia experience loss of appetite, extreme weight loss, fatigue, and immune suppression. This disease has no effective treatment and contributes to about 2 million deaths annually. 

Hence, the researchers thought of working to separate the cancer-fighting benefits of the keto diet from its lethal side effects. The researchers paired keto with common drugs called corticosteroids to prevent cachexia in patients with cancer. 

They found that corticosteroids reduced the tumor size and extended the survival rates of the test subjects.
