Unless you hide under a rock or live in a cave, you will have heard of the latest lifestyle craze - intermittent fasting (IF). Members of your family are doing it, and so are your friends, gym buddies and maybe even your doctor.
The regimen involves fasting for certain hours of the day, or for entire days, consecutively or not. Some people go on it to lose weight and say they are smaller around the waist too. Others do it to feel energetic and focused.
