Healthy Lifestyle Tip: Change Your DNA with Just 20 Minutes of Exercise
You might think that the DNA you inherited is one thing that you absolutely can't do anything about, but in one sense you'd be wrong.

A series of experiments have revealed that just a few minutes of relatively strenuous exercise can dramatically change a person's DNA. The changes are not to the code of life itself, but to its 'punctuation.' These chemicals activate, silence, and crank up genes and their actions.

In the case of muscle, exercise appears to crank up the genes needed to burn fat and sugar and support the body. Just 20 minutes pedaling flat out on an exercise bike makes a difference, the journal Cell Metabolism reports. Researcher Juleen Zierath, of the Karolinska Institute in Stockholm, said: "We often say that you are what you eat. Well, muscle adapts to what you do. If you don't use it, you lose it and this is one of the mechanisms that allow this to happen."
