Restricting food intake, also known as caloric restriction (CR), involves reducing the number of calories consumed while still maintaining essential nutrients. CR offers several health benefits, including improved insulin sensitivity, reduced inflammation, and increased longevity.

In humans, some studies have shown that CR can improve cancer chemotherapy treatment outcomes. In a study published in the Journal Cancer Research, researchers found that patients with breast cancer who followed a CR diet during chemotherapy had fewer side effects and a better quality of life compared to those who did not follow a CR diet....
