Even though it’s really nothing new, Intermittent Fasting has gotten very BIG in the past couple of years. Hundreds of thousands (maybe millions) of people are using it to lose weight, maintain low bodyfat levels, build lean muscle mass, boost energy, feel better, and improve their overall health. There’s a very popular new book out called FastDiet that includes a “lite” version of the method and is getting good reviews on Amazon. LeanGains is a well-known IF-based program that is at least partially responsible for the recent surge in popularity online.
I’ve used intermittent fasting on and off for years — beginning back in college in the 90’s before I’d even heard the term! — and I believe it’s a very powerful eating strategy. It’s especially effective for maintaining steady energy levels throughout the day and allowing the brain to think/function optimally. It’s one of the few practical dieting methods for losing fat while gaining a significant amount of lean muscle tissue at the same time. Also, IF is wonderful for people (like myself) who have a hard time giving up starchy carbs and sweets (although it can also be paired with a low-carb Paleo-style diet with great results!).
