Intermittent Fasting (related to 5:2 Diet, or Alternate Day Fasting) was popularized by the British physician Michael Mosley in 2012*. In essence, the method calls for two separate fast days in a week. On a fast day, you consume a quarter the calories you usually take in. On regular days, you eat what you normally do.
I tried Intermittent Fasting for 10 weeks and was impressed. Here are some of my thoughts.
Weight watching requires will-power. Regular weight watching programs imply will-power 24/7 and that continuous tension is hard to bear. Intermittent Fasting means you will only need to watch what you eat for a short period of time (Intermittent tension) making it more manageable. When I wake up on a fast day, I mentally tell myself “it is game day” and I am on game mode. I treat the calorie-watch like a sport…but just for that one day, knowing that when I wake up the next day I can relax the tension and eat normal again. I find this intermittent tension much more manageable.
There is a parallel development in long distance running. In recent years, it has become popular that you run for 10 minutes, walk for 1 minute, and repeat this cycle. The idea is that this breaks up the psychological and physical tension so the runner is overall more relaxed. With the 1 minute breaks, many runners run faster when they run and actually improve the overall time (run-walk combined).
On a separate blog I will give some figures related to Intermittent Fasting.
