Hey all! So, I have been using Spark and a FitBit. I stopped using the Fitbit before because I felt it was not picking up my renovation work, but now the work is not as strenuous so I'm trying it again.
I've also been posting to the Sparkpeople Virtual Weigh-in group and I've noticed that as an athlete, my weight varies a lot. The reasons include hydration/electrolyte balance, varying amounts of food eaten, muscle rebuilding after heavy workout days, greater amount of muscle mass storing/losing various amounts of carbs/water depending on the day/workout, etc. So, for these reasons, even if I weigh at the same time of the day, just using a single point every 7 days is not informative. It is more visible if I weigh daily and track a 7-day average.
So with that, the weight loss has averaged around 1/2 lb a week. Weekly losses have been 0.8, 0.7, 0.4, 0.2. The last week I am happy I lost, I had relatives in town and we ate out or at someone's house for 5 days... including plenty of cake, pizza and donuts.
That being said, I've noticed the weight loss slowing as I increase my running mileage, so I believe I'm eating too much to compensate for the running. I'm tracking, but perhaps because of my experience with running, my body is efficient at it and so doesn't burn as many calories as the calculators say. I know my days that I do not run, I am also hungrier with the deficit the Fitbit gives me.
Fitbit underestimates how many miles I run. You can manually change the stride length to correct for this, but my stride length changes depending on how fast I'm running, so that doesn't help. I've been manually filling in the actual mileage and so it will increase my mileage and calories burned. I am going to stop doing this and see if it does the trick. I don't need that much of a boost there since I've been losing to some degree. I have noticed a definite performance decrement due to lowering calories. I expected some of this and expect it to return to normal once I've lost these last 10 lbs. It's not only the lowered calories, I have been increasing mileage, which is hard to do while maintaining speed, not to mention being on a diet.
Ok, all for now! Hope everyone's making progress toward your goals!
