    You didn't ruin your metabolism. How many miles do you walk in the time you're on it? 1000 calories implies >10 miles, which would take longer than you mentioned, assuming you're walking slowly and not running.

    My HRM said 974 calories with an hour of walking yesterday. I did about 2 1/2-3 miles. I am very overweight and out of shape.

    Even at 3.5mph and 240 lbs., average burn would be 469 for an hour. See very last cell in chart in link below. Unless you're much, much heavier than 240, I'd be skeptical of that HRM value.

    I'm skeptical of the chart because it does not take into account a person's fitness level, heart beat, oxygen level, gender. In other words, it's very general in all respects.

    ETA:ah, I see her values for her heart rate monitor are high. Perhaps it is not calibrated correctly,

    After searching around a bit, I read about how large amounts of low intensity cardio can ruin your metabolism...

    That is complete and utter bull****, your problem lies elsewhere.

    Starting with your burn estimates - at your weight, to burn 1000 extra calories you'd have to walk 20 miles - so scale accordingly.

    And surely somewhere in all that searching you must have come across an explanation as to why HRMs are completely inappropriate for estimating calorie burns for walking exercise....there are literally hundreds of posts on that subject right here at MFP alone....
