    Doing well. Keeping my calories at 1200 or under. Carbs at 15+/- 3. No hunger or cravings. Walking 5 miles 3x/week on my days off.

    Today (8/22) its raining (and going to most of the day) so I dusted off my Elliptical, I haven't used since I broke my leg really bad in 10/15. Put on a TV show and did 72 minutes. I was sweating and exhausted but I did it! That time was picked as that is usually how long my first walk takes and is 3.4 miles. Elliptical said I was at 4.6 mph and did 5.5 miles!

    I have a question. How accurate is MFP with the exercises? It said I burned 1001 calories! Usually I burn about 530 with my 5 mile, 3x/so walk total. Granted I was more tired than my 3-3.5 mph walks, but I was surprised at that number. I know its based on my daily weight.

    Just wondering what others think, if it's pretty accurate.

    How accurate? That is the question. Estimates of calories burned per minute vary quite a bit, depending on factors like level of effort, body weight, HR, etc.

    Your exercise was 1001 cal / 72 min = ~14 cal/min.
    That's not out of the realm of possibility.

    I can only tell you my experience:
    I have a Garmin watch that syncs with MFP, so the estimate of calories burned comes from Garmin, not MFP.
    My swim this morning was roughly 510 calories in 70 minutes -- that's a bit over 7 cals/min. My Garmin categorized the aerobic impact of this swim as "4.2 Highly impacting (in a 0-5 range)". That's pretty typical for me. My other exercises are usually anywhere from 5 cals/min to 12 cals/min.

    I think MFP tends to overestimate calorie burns for exercises, at least all the exercises I've logged. I have entered my own calorie burns, and MFP adjusts them automatically as I lose weight. I'd much rather underestimate than overestimate the amount of calories I burn. I find that other sites cite much lower calories for the same exercise.

    My boys were competitive swimmers. Swimming is an ALL INCLUSIVE body workout. PLUS you have to control your breathing TOO! And a professional football player, who also played basketball and baseball in high school, also agreed with me, when his son swam to keep his asthma in check in winter season with my guys, and his son went on to Div 1 college football and also a Pro football player.
