Just for the first month it doesn't matter what anyone says. I'm doing ADF for sciencethis - protein is required to help rebuild/repair your muscles. But as the OP has already pointed out - he's doing it his way by starving himself so I don't think it matters what anyone says.
After we see how progress has been like at the end of the 4th week - and I get to weigh myself then - I will be happy to try something different, and compare results.
This first month is sort of my "control" month. I'm doing something I've done before, but doing it properly (with no snacks!), and using it as a benchmark.
