A new study finds one of the strongest links yet between obesity in older women and cancer the findings published in the journal cancer research show.
Women who lose at least 5% of their body weight can see a dramatic reduction.
And the sort of inflammation.
Related to several types of cancer let's bring in now doctor Don -- -- And and doctor you are -- particular practitioner and an author of eat this and live.
But this is about eating a little bit less tell me what impresses you about this particular study.
Well interesting study found that overweight and obese postmenopausal.
Women were much more likely.
It -- to develop -- -- it developed cancer but if they simply would decrease their calorie intake.
God then they reduce the risk of cancer went out what was centrist think.
Is if they had the calories down to 12100 to 2000 calories a day they significantly decrease the risk of cancer by like ten excuse me about.
We know it's interesting too because this is not about losing a ton of weight -- if you make that kind of adjustment 2000 calories and still quite a bit to eat.
How are absolutely 2000 calories is -- get that with lots of vegetables fruits -- -- and it fits in lower in the sugar.
Our contest but Harris was so excited about this study there were four groups of these postmenopausal women the first group simply lowered their calorie intake.
And the second group just exercise 225 minutes a week.
The third group used those decrease calorie intake and exercise and the fourth where it was a control -- no change.
The exciting thing is the first and third group.
Lowered their body fat by ten and -- give me eight and 10%.
But they decrease -- inflammatory markers by 36 and forty wow percent.
Not inflammation is -- linked to heart disease and cancer.
And so this study shows that just a little bit a weight loss.
Lowers your risk of -- lowers his inflammatory markers lowers your risk of cancer.
But the exercise alone group did lower the inflammatory markers or lower the -- significantly.
Now why is that.
Well that's interest -- because for some -- exercise alone.
Will not lower these markers or lower the body weight significantly the key is -- the body weight.
Just say we've known that CRP is this main inflammatory marker and CRP is primarily produced by belly fatter visceral fat.
When you reduce body fat especially the belly area you're reducing inflammation and reducing chronic disease like cancer and cardiovascular disease.
All right before I let you go I wanna talk about inflammation 'cause I wanna make it clear this isn't the same thing is when you -- your telling your -- swells up.
Right exactly say there's they're good side of information about -- the good side of inflammation as you get a sore throat and mobilize your immune system.
Or you have an ankle swollen and it also helps to split the entry.
Chronic inflammation with elevated CRP.
Set yourself up for heart disease.
Cardiovascular disease cancer -- alzheimer's disease and other inflammatory states simply bought unremitting.
-- in elevations of nuclear factor kappa beta.
That -- these inflammatory chemicals that constrict arteries and cause disease.
Now those are a lot of big words that you and I were talking off camera very simply it's the stuff you can't see.
And the study points out that if you just lose a little bit away and do a little bit of exercise you can make a huge difference the last fifteen seconds to you doctor.
Right because they -- this study is simply just a small amount I'm talking about five to 10% which is only about ten to twenty pounds.
There's this powerfully decrease in chronic inflammation -- are the reducing syrupy by as much is 41%.
And that's more than most medicines can do so just a little bit -- -- portend a twenty pounds.
That's the key -- -- -- more than most medicines can do -- doctor -- thank you so much for joining us.
