That Tracking App May Be Overly Optimistic

I decided to go old-school on my journaling with this current weight-loss push and go back to pen and paper, which is the method I used for years and years. It’s the method that was available back when I started losing weight the first time. Hell, smart phones hadn’t even been invented when I was losing those 200 pounds, it was pen and paper or nothing. No apps, no FitBits, just honesty and a little booklet in my purse.

I realized almost immediately once I started my paper journal this weekend that MyFitnessPal, bless their hearts, were over-counting the calorie burn I was getting with my workouts. That’s the app I’ve been using over the last year or so. Uh…that may explain why I wasn’t getting the results I thought I was, right there! Using pen and paper and the Calories Per Minute calcs I’ve been accustomed to with the program I like best, I’m back on track. My numbers may come down a bit for exercise burn, but I feel it’s a more accurate picture.

Here’s an example: Yesterday I went for a bike ride, as I mentioned. Probably around 13 miles out and back, took me about an hour and 15 minutes (including stops at traffic lights). I estimate that calorie burn as about 525 using my calorie burn rate of 7 cals/minute (“medium intensity” physical activity). Pretty good, and probably pretty accurate, because while biking is great for your legs, they aren’t bearing any weight when you’re doing it. Biking is a seated exercise, always keep that in mind! MyFitnessPal, for the same workout, at a “moderate” pace, estimated 953 calories burned. NO. WAY. Even for “light” bicycling, MyFitnessPal says 714 calories. Still too high. If I’d been using MyFitnessPal and trusting their numbers, I might have thought I could go crazy and eat anything I wanted. That’s no good.

I’m going to stick with my booklet and pen for now. Technology can be great, but I like having a solid foundation in understanding how these numbers work and are created independent of an app.

Also, for those who want to argue it – I know how my body works, and I know that 525 is a lot closer to reality for me than 900+ for an hour and a quarter of biking. I have 13+ years of weight math that tells me the lower number is more accurate. Besides, wouldn’t you rather underestimate your exercise burn than overestimate it?

    My nutritionists at Kaiser advise not to count exercise towards daily calorie intake. They suggest setting a daily goal and seeing how that works. For example, I currently aim for 1300 calories intake with maximum 1500. (I’m only 5’4″, and 54 years old.) I try to average 10,000 steps a day walking, and something a little more strenuous on the weekends. When I stick to my plan, I lose about 1 pound most weeks. I still have about 25 pounds to lose, and I’m breaking it up into 5 lb. increments.

      There are a lot of different theories on using, or not using, exercise calories. I think the one thing everyone can agree on is that they should be calculated correctly!

    Is it possible to calibrate the app to your metabolism? If not, invent one that does and make your fortune 🙂
