I started down a road I imagine many of us have gone down - calorie counting. I saw a dietician recently and she recommended a smartphone app - MyFitnessPal. It's a standard calorie counter, but one neat feature is a barcode scanner, so instead of keying everything in you can just scan the UPC on an item and it'll most likely have the calories and nutrition information in there already. And ince some people on the internet seem to love entering data, many common fast food items (Jimmy Johns, Starbucks, etc) are already in there.
You enter in some data, like current weight, height, goal weight, fitness goals, and it'll compute your ideal calorie needs. Similar to calories from food, you can enter exercise in your diary, and it'll compute the calorie expenditure.
This is my question: anyone know how accurate the exercise calculations are?
I just finished a 2 hour, 25 mile ride, with an average speed of 12.5. Entering this into MyFitnessPal (120 minutes of cycling 12-14 miles per hour), given my weight, yields a calorie expenditure of 2093 calories.
That figure seems a little extreme - perhaps for someone who is totally out of shape, but I like to think I'm not. I did have a largish breakfast, and stopped part way through for a treat at Starbucks, but I feel like I should be demolished after that - I'm merely a bit tired and hungry.
If these are accurate, well, I guess I have some license to eat a lot, because I just spent 3/4 of my daily calorie needs in 2 hours. If it's not, I need to work on a more accurate measurement. Thoughts?
