My BMR - my thought process
Saturday, July 12, 2014
So I've blogged about this in the past, how I don't use the BMR that spark comes up with - I still think we should have an option to enter what we get running our numbers through the typical formulas - a challenge for another day. (Several other sparkers I know take a couple hundred off their number with similar success.)
Currently, spark says my BMR is 1732. Most obviously found when I run reports and get my daily differential. In the most recent past I was using 1500 instead. But a few weeks ago I was thinking, well...maybe they are right. I was eating at the high end of my range and exercising with a goal to lose half a pound a week and pretty consistently (for several months) I was losing about half a pound a week. The occasional setback of course for failing to stay in line affected this but over the last 12 week BLC I lost 5.4 pounds (my goal was 6). I hadn't had that kind of consistency in the past. This round of the BLC I was on track to reach the same goal until I changed up my BMR.
Before I made the change.... I thought since I get so much fitness in and it not a slow stroll around the park...maybe I was using the wrong level of activity in computing my BMR. I use sedentary since I sit at a desk all day during the week and most of the weekend on the couch (or so it seems). I recalculated it for the next level and got a number similar to what they have for me on Spark so I switch a few weeks ago. It has made it very convenient to quickly track my differential but I've noticed over the last two weeks that my weight loss has stopped and is drifting in the wrong direction. There are other changes that have occurred in this same period but I do think it boils down to eating more (allowed by the higher BMR). The last couple weeks my fitness has been higher so I'm actually showing larger daily and weekly differentials but the weight loss is not there. I'm baffled. Some of the members of one of my teams have been in a similar place with a lack of losses and we talked about these very points. So... my ramblings are just to track my thoughts and I've decided I'm going back to 1500 BMR (adjusted for my food choices as I can't stick that if I burn 600 or 1000 calories playing tennis or running 6 or 8 miles). I get sick and end up struggling with other issues.
So at 1500 base BMR, I keep my differential to around -250 a day with a goal of half a pound loss each week.
In one week I go on vacation but we have lots of fitness (hikes, and lots of places to go) planned and I have never had a problem with poor food choices or over eating when traveling. Usually because they are very active vacations and this one will not be any different.
Hoping in the next week and a half I get it all back in line for the final weighin for BLC and can reverse the increases for my WI's for the 5% challenge as well.
If it ain't broke why change it!
