According to a recent study by the University of Alabama at Birmingham and the University of Colorado, it only takes a few weeks of healthy eating to generate lower blood pressure and cholesterol. Dr Campbell, one of the researchers said, “"These findings should encourage people to try again if they fail at their first attempt to adopt a healthy eating pattern," …It seems that your body isn't going to become resistant to the health-promoting effects of this diet pattern just because you tried it and weren't successful the first time. The best option is to keep the healthy pattern going, but if you slip up, try again."
