Some low-fat diets are full of unhealthy foods like sugary snacks and processed meats. This study looked at women who ate those kinds of low-fat diets and found they were more likely to get breast cancer after menopause.
Surprising Findings
No significant link was found for overall or premenopausal breast cancer — only postmenopausal.
Most people assume diet affects breast cancer risk uniformly across life stages. This suggests hormonal changes after menopause may make women uniquely vulnerable to poor-quality low-fat foods.
Practical Takeaways
If you're following a low-fat diet, check if you're replacing fats with sugary cereals, snacks, or processed meats — swap them for whole foods like vegetables, legumes, nuts, and fish.

It’s not just about eating less fat or less carbs—it’s more about whether the foods you eat are healthy (like veggies and whole grains) or unhealthy (like sugary snacks and processed meats).
Women in their 40s to 60s who eat a low-fat diet that’s not very healthy are about twice as likely to get breast cancer after menopause compared to women who follow that same kind of diet less closely, based on a study that followed them for over 12 years.
