Martin Berkhan designed Lean Gains, an Intermittent Fasting protocal, and has been able to remain around 5.5% since 2007 and has helped many acheive the same. His diet is about being able to gain lean muscle mass while simultaneously dropping bodyfat or gaining LBM without gaining bodyfat. The method is via intermittent fast in which the person does not eat for 165 hours out of the day and then gets in the required calories for acheiving their goal within an 8 hour feeding window. This allow a lotmore freedom in what you can eat because nutrient dense foods are a must to get in your caloric needs within that window. This dietary stategy aslo addresses insulin sensitivity and leptin issues that can drastically accellerate how quickly you can lose body fat.

Fasting and feeding
My general position on the fasted phase is that it should last through the night and during the morning hours. Ideally the fast should then be broken at noon or shortly thereafter if you arise at 6-7 AM like most people. Afternoons and evenings are usually spent in the fed state.
However, the fast could also also be broken later in the day depending on your personal preferences and daily routine. I personally tend to break the fast as late as 4-6 PM since I work well into the night and rise later than most people with normal jobs.
The recommendation for fasting through the earlier part of the day, as opposed to the latter part of the day, is for behavioral and social reasons. Most people simply find it easier to fast after awakening and prefer going to bed satiated. Afternoons and evenings are times to unwind and eat. For adherence reasons during dieting, I've also found that placing the feeding phase later in the day is ideal for most people
