Obesity is a very well recognized cancer risk factor. This fact is a very powerful stimulant to lose weight. But can it be neutralized? The only thing that needs to be done is to prove that it is not obesity that causes cancer, but something else. Hard to do, but possible. And in my opinion, that is what a new study might be doing intentionally or unintentionally. Take a look yourself.
According to the new study, published in the Journal of the National Cancer Institute on December 30, 2008, “Insulin, Insulin Like Growth Factor 1 and Risk of Breast Cancer in Postmenopausal Women,” it is not obesity itself, it is your high insulin level that causes cancer. The conclusion is that we need to control insulin levels.
But how about weight? If it is all about insulin, then do we need to lose weight or not? The study states, that “this (obesity) association was attenuated by adjustment for insulin” http://jnci.oxfordjournals.org/cgi/content/abstract/101/1/48.
The way that I interpret this study is to mean that if we watch our levels, we have no need to lose weight. I don’t agree with this statement.
When does an obese woman have low insulin level? When the weight gain is not for a long time and her body is still sensitive to insulin, being able to bring its sugar down with less insulin. But what happens when it is a long time, when her body gets too many calories? It loses its ability to respond properly to insulin and bring sugar down. This is called insulin insensitivity and the result is a high insulin level.
The bottom line is that a high insulin level in an obese, postmenopausal woman might be the result of a long time of being obese, leading to increased cancer risk. So you need to lose weight and change your lifestyle and not just watch your insulin level.
