Is your diet increasing your risk for cancer? Shocking new findings on intermittent fasting!
- Replies 0
Intermittent fasting has quickly become one of the most talked-about health trends, especially among older adults looking for simple ways to boost well-being.
From weight loss to better brain health, its promises seem almost too good to ignore.
But a surprising new study is raising fresh questions about what happens inside the body when we fast—and what that might mean down the road.
Intermittent Fasting: Popular But Not Without Risks
Intermittent fasting has become a popular dietary trend, praised for its potential to help with weight loss, improve heart and brain health, and reduce oxidative stress and inflammation.
Many Americans over 60 have turned to this eating pattern as a way to manage their health and well-being.
However, a recent study conducted by researchers at the Massachusetts Institute of Technology (MIT) has raised concerns about a possible link between intermittent fasting and an increased risk of colon cancer—at least in mice.
What the Study Found
The study divided mice into three groups:
A Surprising Discovery with a Serious Warning
Surprisingly, the mice that fasted and then re-fed showed a significant increase in the multiplication of intestinal stem cells compared to those that didn’t fast.
While cell growth can be a sign of healing and renewal, there’s a downside: rapid cell division can lead to mutations.
If these rapidly dividing cells mutate, they could become precancerous, potentially setting the stage for colon cancer.
To investigate further, researchers introduced cancer-causing genes to make the mice more vulnerable to tumor development.
The mice that underwent the fasting-refeeding cycle developed more precancerous polyps in their intestines than those that ate normally or fasted without refeeding.
Dr. Omer Yilmaz, the study’s lead author, emphasized that these results apply only to mice and that human biology is much more complex.
Still, he suggested that the timing and content of meals after fasting might matter—particularly if the post-fast meals include mutagens, like charred meat, which may increase the risk of cancerous lesions.
What It Means for Older Adults
Intermittent fasting includes several styles, such as:

Time-restricted eating is especially popular with older adults looking to simplify meal schedules.
And while intermittent fasting has been associated with numerous health benefits, this new study is a good reminder that long-term effects—especially for seniors—are not yet fully understood.

What the Study Found
The study divided mice into three groups:
- One that fasted for 24 hours without eating.
- Another that fasted for 24 hours and was then allowed to eat freely during a following 24-hour “refeeding” period.
- A third group that was allowed to eat at will throughout the experiment.

- Alternate-day fasting
- The 5:2 method (fasting two days per week)
- Time-restricted eating (eating all meals within a 10–12 hour window or less)
