I think this is right on and I believe results are going to vary depending on the individual's conditioning to begin with. Especially if one is new to training (as in never lifted anything) along with body fat/muscle ratio and general health.
If EVERYTHING is done text-book style, its going to take a week just to slow the train down, another to stop the train, one week to reverse the train, and after that if you still have the resolve, you are going to get those results not all at once but it will happen.
We are hammered with commercials and magazine glossies about getting results fast if you only do
this for 20 minutes a day-hype. The only people on the planet that can eat day-old pizza from under the bed,
and all the other things (we) used to eat are teenagers and 20-somethings or people who are injecting HGH. Women have the harder row of it considering our hormonal panel is is a circuit board out of Star Trek and are so directly dependent on everything functioning in tandem. In comparison, men rely on their very abundant hormone testosterone and others such as DHEA, but I digress. Men will see faster results, and once a man sheds enough fat to stabilize estrogen, he's going to be in pretty good shape for a very long time. Muscle also produces testosterone, its a win/win with men.
Generally speaking (and not always of course) women are supposed to have 20% fat at certain times of our life and its pretty hard to convince the body otherwise unless you are working at it at least 90% of the week. Women need body fat to produce estrogen after menopause, so you got that mighty struggle to deal with. But, I'm suspecting our adrenals, thyroid and pituitary glands have taken a hit from years of bad food culture, heavy metals and chemical laden water.
I guess what I'm trying to say, its never going to be predictable when it comes to losing fat and maintaining muscle. What one does may not work for the other, but there are other nuances to this, like supplements and eating enough fat and how is your Vitamin D level and your gut health? Your gut bacteria outnumber all the cells in our body 10 times over, and bad gut means poor absorption and a domino affect. There are plenty of other *players* in this arena.
I need to be quiet now...omg talk about a soapbox tower!
