Intermittent fasting-a diet that focuses on when rather than what a person eats-may be a good way to lose weight and improve cardiovascular health. One version, time-restricted feeding, involves eating only during a certain time window (usually eight hours) over a single day; another approach limits a person to just 400 to 600 calories daily for several days over the course of a week.

There are a number of steps to take when starting an anti-inflammation diet, such as the Mediterranean diet. The steps boil down to some dos and don’ts.
