So clearly it is possible to lose more than the stock-standard 1-1.5 lbs/week of true fat without muscle loss. And understanding why and how means understanding why muscle loss tends to occur on a diet in the first place.
Arguably the biggest reason (and the one we have only limited ability to control) is shifting hormones: falling leptin and testosterone, increases in cortisol, and a whole bunch of other (bad) stuff happen during dieting and most of these things become more pronounced the leaner you get. Cyclical diets (like the Ultimate Diet 2.0) and strategies such as The Full Diet Break go a long way towards helping with those issues since the periods of high-caloric intake help to restore hormone levels back towards normal (they can’t ever restore them completely).
Of course, as noted in those articles, a big reason bodybuilders use so many drugs is to fix problems while dieting. With enough testosterone, thyroid meds, thermogenics, anti-cortisol compounds, appetite suppressants, etc. they can basically replace everything that the body isn’t making anymore.
An additional factor is that people’s ability to train intensely often goes down on a diet and maintaining the appropriate tension stimulus to keep muscle is key to avoiding muscle loss. This is one of the reasons I find the whole idea of increasing volume and frequency of training on a diet half-assed; as discussed in Weight Training for Fat Loss Part 1 and Weight Training for Fat Loss part 2, people do better when they cut volume and frequency and focus on maintaining intensity.
