This is the only abstract of a scientific article i could find
http://www.lifespan.org/Services/BMed/Wt_loss/NWCR/Research/05.htm
It says no, but that organization has an axe to grind and all 8 of their scientific studies support the central thesis of the website.
Is there evidence that permanent weight loss (say 40 lbs or so) will affect RMR for life? I assume that since alot of people who lose weight also lose muscle and don't weighttrain than that might give the impression that weight loss = slower metabolism because metabolicly active muscle is lost, but if you keep or build muscle will your RMR still slow?
Somewhere on the website i listed it says that the average permanent weight loss individual eats 1400 calories a day and burns an extra 400 through physical activity (i can't find it on the page). Assuming that is true wouldn't that put their maintenance calories at 1000 a day?
I found a link but one that isn't from the original site.
http://www.vegetarian-diet.info/weight-control-vegetarians.htm
On average, registrants’ report consuming about 1400 kcal/day (24 percent calories from fat) and expending about 400 kcal/day in physical exercise.
..........(cut)
Successful weight losers appear similar to normal weight individuals in terms of resting metabolic rate.
What i don't get is how can they have the same RMR but only eat 1400 calories a day while burning 400 extra in physical activity?
Then again this site

says 80% are women. So their metabolism is probably slower anyway, plus dieting w/o weight training will burn off whatever little muscle they had to begin with.
