Well, in a way it is like a heartbeat. One week I lose 3+ pounds, and the next week I lose one or nothing. At least my "weight-heartbeat" is staying above the line -- meaning weight loss (in this case, below the line would be weight gain, and that would not be good!). So technically I guess my weight is more like a mountain range -- some of the peaks are high and some are low.
I have a theory about this. I really think it has nothing to do with what you eat or how you excersize. I think when your body loses a bunch of weight (for me, 3 lbs or more in a week is a bunch of weight), then it needs the next week to "catch-up", so it doesn't lose as much. I'm okay with that personally, because this is a weight loss journey -- not a weight-loss race.
Do you like my theory? It is not based in any medial or scientific fact. Just my observation. I guess it really doesn't matter that much -- if I don't lose that pound one week, perserverence tells me that I will lose it the next week, or the week after that.
So I bet you can guess how much I lost this week -- another pound. That brings the total to 16.6 pounds.
How did you do this week?
