Wow....that's some pretty good info!!! So what he's saying is that yes, the metabolism will slow down, but not enough that it'll offset the calorie deficit and/or result in not losing weight.
The thing that bothers me is that I've now had about 4-5 people give me first-hand personal accounts of how they were plateaued and not making progress...and then they ate 300 more calories per day and suddenly weight-loss resumed! I believe these people...these were their experiences!
At the same time, we have the info mentioned above and my own expert nutritionist insisting that it's still calories in vs. calories out. It still goes back to underestimating calories and maybe my body becoming very efficient at doing all this exercise?
Just the same, today was 2 spin-classes back to back and about 30 laps (back & forth = 1 lap) in the pool. I'm sure I got some good exercise out of it, probably about 2k calories burned. I didn't have my HR-monitor, but I know what 3.25 hours of cardio will do....and I really put it out in spin today! Took in some good breakfast and drank during class...gave me energy to lay it down!
As for diet, I'm eating differently, but still falling back into a large deficit. The good news is that I really feel & think my body is now responding...taking that week+ off from both training & dieting has seemingly reset things. I dunno, I'm feeling lean, my clothes are getting looser and I'm making progress. I always think of it as motion: I'm on the gain, or on the lean....right now I'm headed in the lean direction. The thing I have to keep in mind is that I lost over 40 pounds solid fat and still was able to look in the mirrror and wonder when I'd finally see a difference...based on that, I have no right whatsoever to look in the mirror each day and expect to see the same dramatic difference as you see when you, per se, get a haircut.
So...I can't count on my perspective in the mirror, I shouldn't look at the scale, the body-fat calipers are obvious off (cause I ain't no 12%) and that pretty much leaves me with NOTHING to guage my progress!
I'm cool. I'm on it, at it and sticking with the game plan.....
