Intermittent fasting is gaining popularity for helping with weight loss because it's easy and it works. Basically, you choose a window of time to eat, and a window to not eat (fast). 16:8 is a common method, where you eat from noon until 8 p.m. Since you're eating only a certain number of hours a day, it helps you cut down on daily calories, as long as you don't overeat during your eating window!
