Study: Eating during certain windows may reduce risk for cancer

The Endocrine Society’s Annual meeting yielded some fascinating finds this past Saturday. Two independent studies in particular present strong data regarding the hormonal impact our eating schedule has on overall wellness.

Adnin Zaman and her colleagues showcased promising research exploring how eating later in the day effects BMI and weight gain. An analyst of 31 overweight and obese adults provided further insight into the way our body’s ability to convert calories into energy diminishes as the day grows old, seeing us pack on fat more readily.

Unfortunately, over-eating past dinner time might additionally come with graver consequences than an expanding waistline.

According to the lead researcher behind a new study, Dr. Manasi Das, an adherence to a time-restricted diet can dramatically reduce your risk for breast cancer.

Three studies, one astonishing conclusion

In the first study, mice were put on a  60% fat diet regiment in order to make them obese. After 10 weeks passed, they were split into two groups.

One group was given access to food 24 hours a day while the other group was only permitted to eat in an eight-hour window period at nighttime (rodents are nocturnal thus the most active at night). Three weeks into their assigned diets, the mice were injected with breast cancer cells.

The second study organized the genetically modified mice into two groups – one group was given 24-hour access to food and the other was assigned time-restricted access to food.

In the final study, mice that adhered to a low-fat diet were given either a saline control, or an insulin pump, and then examined against mice on a high-fat diet put on drugs meant to reduce insulin levels.

An ultrasound scan of all the rodents involved in the three studies revealed that the time-restricted diet drastically slowed the rate of tumor growth in mice on a high-fat diet and lean mice alike. Dr. Das explains: “The results suggest the anti-tumor effect of time-restricted eating is at least partially due to lowering levels of insulin, suggesting this intervention may be effective in breast cancer prevention and therapy.”

Lower insulin levels concurrently impede the speed of growth of cancer cells, in addition to slowing down the development of tumors.

It’s also important to note that the mice put on medication that decreased insulin levels (diazoxide), experienced a slower growth rate than mice fitted with an insulin pump.
