Just a few minutes a day of strenous exercise can alter your DNA. The changes occur within the chemicals that activate or silence genes and their actions. Exercising seems to increase the activity levels of genes that are used to burn fat and sugar.
However, you must exercise strenuously for this to occur. This means you should be out of breathe and have difficulty holding a normal conversation.
Researchers removed tiny strandes of muslce from participants and found that it takes just minutes for the changes to occur.
Interestingly enough, the study mentions that cappucino can micmick the effects of exercise, but it would take 100 cappucinos.
