One thing that is always lost in threads like the one linked is this:
That exception is beginners. Complete beginners, who haven’t built any real muscle mass in the first place don’t have to worry much about muscle loss while dieting (just about any training will maintain it). (taken directly from Lyle)
The majority of these threads and concerns are from beginners. The thread linked above was started/about a beginner as well. Honestly, pretty much every single professionally designed program will work for a beginner.
Lyle is actually doing a 2 part article on this very topic as we speak. You can read part 1
here and part 2 is scheduled to be out today which talks about practical issues of how to put together a weight training program during dieting in terms of volumes, frequencies, scheduling, etc.
I honestly think people read way too much information and see too many contradicting opinions and get confused. When the answer may be as simple as both routes work. The important thing is just to pick a route and stick with it. When you see results that you don't like or you stop getting results, it's time to try something new and evolve.
