Time-Restricted Eating May Help Curb Tumor Growth


Time-restricted eating may help curb tumor growth. Researchers have already shown a link between obesity and the risk of cancer. So, doctors suggest reducing caloric intake can help prevent tumors. A new study says that prevention may be more about when you eat your meals.

Previous research has concluded that obesity is associated to an increased risk of developing certain types of cancer.

A new study led by researcher Manasi Das, Ph.D., from the University of California in San Diego, explain that rather than focusing on what they eat, a person may benefit from simply timing their meals differently.

Das and colleagues conducted this research using mouse models. In the first stage the team induced obesity in female mice with no ovaries to simulate postmenopausal conditions. They fed the mice a a 60-percent high-fat diet for 10 weeks.

Then, some of the mice had their unrestricted access to food for 24-hour and food was restricted to the 8-hour window for the rest of the mice.

The researchers injected injections with breast cancer cells to all of the mice for 3 weeks during the study.

In the second stage of the experiment, the scientists genetically caused mice to develop breast cancer. They fed an unrestricted diet to some of these mice, while the rest had access to a time-restricted diet.

Their analysis found that tumor growth was less in obese mice who were in time-restricted diets, compared to those who ate unrestrictedly.

“Exploring the ability of time-restricted eating to prevent breast cancer could provide an inexpensive but effective strategy to prevent cancer impacting a wide range of patients and represents a groundbreaking advance in breast cancer research,” Manasi Das said.
