Breaking News! More from yesterday's blog study.

Yesterday, we reviewed how calorie restriction and diet reduce harmful inflammatory biomarkers, but today, more from the same randomized control trial from Fred Hutchinson Cancer Research Center, lead by Dr Anne McTiernan.  Today's publication online in the Journal of Clinical Oncology includes the response of sex hormones to exercise and diet in the aforementioned group of women


The report is of one year follow-up of 438 women, mean age 58 years, mean BMI 30.9.  The groups:

1. caloric restriction
2. regular exercise
3. diet and exercise
4. control

The data are as you might expect: sex hormone levels (estrone, estradiol, testosterone) all decreased with weight loss and exercise.  They saw a modest decrease with exercise, more decrease with weight loss and the greatest decrease in the hormone levels with weight loss and exercise.

This study gives us more data on weight loss and exercise mechanisms for breast cancer risk reduction.  

In summary, the study itself through separate publications, demonstrates that weight loss and exercise favorably decrease hormones and inflammatory biomarkers that are linked to more breast cancers.

Kind of makes you want to eat less and exercise more!

Together we can prevent 75,000 breast cancer cases each year!
