Not sure why I'm posting. The answer is (of course) as simple as "They're wrong".
Been having trouble keeping up in races lately--I hit my max when I should only be in zone 3 or 4. I thought it might be due to an injury and about 2-weeks off the bike. Then I got on the scale: I had gained about 5-10 lbs. So, back on the Diet Wagon
In the past, I had kept track of calories on FitDay, but they had made some design changes that I didn't approve of, so I went looking for another solution. I went to Spark People to help keep track. But, I'm thinking it looks too busy, so I'm not 100% happy with it. Then I found Lose It! for my iPhone, and I think I really like it. Could be better, but it's got a solid base to start with.
Went out for a nice 2-1/2 hour, 45-mile ride this morning. Thought I'd crank up the time and drop some weight. Now here's the info and dilemma(s) I see so far...
and I just don't trust it.
- Lose It! has me on a 2,200 calorie/day goal to drop about 2 lbs. per week. This does not take into account exercise: it's totally based on resting metabolic rate.
- SparkPeople says I burned 4,342 cals on this morning's ride.
- Lose It! says I burned 3,640.
- My data uploading software, Ascent (for Macintosh), says I burned 2,047 cals.
- Me? I'm a pessimist here, so I think Ascent is more accurate.
- At this point so far today, I've eaten 1200 cals.
- Lose It! therefore has me at a deficit for the day of 4,500 cals and if I eat this many cals for the rest of the day, I'll still be on target to lose those 2 lbs. per week. That's a really big dinner!
Anyone else have a problem with these numbers?
