I've been around low-carb for about 2 1/2 years now.
Way back when, ANY period of no loss was called a "Plateau" or a "Stall" - there was no difference. Then a differentiation came about where a stall was "bad" and a plateau was "acceptable".
Then, some time later, time frames were given to the plateaus and the stalls. Plateuas were short time frames and stalls were long time frames.
Numbers of weeks were then attributed to each. Stalls were 4 weeks or longer, plateaus were 4 weeks or shorter. Now. most recently, stalls are 6 weeks or longer and (I guess) plateaus would then be 6 weeks or shorter.
Hmmm. The first thing that comes to mind is: Grow up.
Weight loss is all about getting back to the weight we were/are most suited to. HOW we get there, - the steadiness (or not) of the weight lost, is completely and totally irrelevant.
My advise is to stick with the program, steadily and totally -- without micro managing and psychoanalysing ever step.... and do this until you get to goal. If you dissect whatever program you are on - too greatly, you will go crazy. If you pick apart every minute, every second, you may very well reach goal, but still be miserable. Lighten up. Your goal will come. Combat anal tendancies while you still have weight to lose - get them out of the way NOW -- , then once you are "thin" you will be absolutely perfect.
