does walking for 2 hours really burn 400-500ish cals???!!

i don’t have a watch to track it but i just googled how many calories does someone my weight would roughly burn for walking for 2 hours and it seems like overestimate. what do you think? i don’t want to overestimate and then eat a portion of the calories back

also should i consider it exercise?? bc i just walk to work now and i go to the gym too. just doesn’t seem as much effort as the gym sorry if this makes no sense

    about 3 miles one way so 6 miles a day 3 times a week and i’m 142lbs and i wouldn’t say u speed walk kind of casual depending if i’m in a rush but i might start walking quicker to burn more

    I walk briskly on a treadmill at a slight incline around 4 mph, burn almost 400 in the hour. If I were sitting on the couch, I would burn 55 roughly in an hour. So my gain is about 325 to 345. If I walked slower I'd burn a little less.

    I am female, 46, 130ish.

    You might figure about 3 calories/minute for walking at a good pace. But there are a number of benefits of exercise. Losing weight is only one of them. Another important benefit is aerobic effect which improves your cardiovascular system. One key to gauging the value of exercise is monitoring your heart rate. A common method of categorizing exercise by heart rate uses heart rate zones. You can figure out your zones by estimating your maximum heart rate using the fomula: HRMax = 220 - age (reasonably good estimate for younger people).

    Then you can compute 5 zones:
    zone 1: 50% - 60% of HRMax
    zone 2: 60% - 70% of HRMax
    zone 3: 70% - 80% of HRMax
    zone 4: 80% - 90% of HRMax
    zone 5: 90% - 100% of HRMax

    Zone 3 is a good zone for getting cardio benefit as well as fat burning.
    It's a complex topic, and it's worth noting that for each person, YMMV (your mileage may vary).

    This seems unlikely to be honest. See the equation that Sijomial posted above. Don't trust numbers on machines.

    Doesn't sound unreasonable. I burn about 200 per half hour or so of walking at a good pace.

    How do you get this number? And is your weight the same?

    I'm a few kilos heavier. I lose weight as expected (or maintain when I'm having a break) so assume it must be about right. Garmin and MFP both approximate about 200 (give or take) for the pace/distance I go.

    Also to note I think I have just tweaked what works for me. I include my daily walking in my activity level rather than logging it separately, as I walk at least an hour at a reasonable pace every single day. Anything greatly over an hour gets logged as additional exercise though. Works for me although I appreciate garmin and MFP estimates can be quite wild.

    Losing weight on schedule doesn't validate specific exercise estimates - it just means all the inaccuracies in estimation of someone's BMR, activity multiplier, food and exercise logging either cancel each other out or they have adjusted based on results (or just got lucky!).

    In retrospect I know my exercise estimates at the time of my major weight loss were inflated, but I still lost weight on schedule as I adjusted my base calorie goal to achieve the results I wanted. Sharing what I now know weren't great methods wouldn't actually be helpful to someone asking if their estimates are likely to be realistic.

    "My elliptical told me I burned a 1,000 cals in an hour and it must be accurate because I lost a pound a week."
    Except of course I didn't burn that much, not even close.

    The math comes out to about 30 calories per mile for every pound of body weight on relatively flat ground. At a brisk, 4mph pace you'd cover 2 miles in a half hour ... 90 cals for a 150 lb person ... 120 cals for a 200 lb person ... 180 cals for a 300 lb person.

    30 calories per mile for every pound of body weight? That makes no sense, you're saying a 2 mile walk would for a 150lb person burn 30*2*150 calories? 🙃 not sure your maths is to be trusted.

    Maybe you mean 30 calories per mile for every 100 lbs??? Not sure where you got that from either though, but certainly a more reasonable guesstimate.

    Just a minor decimal mistake. Basically it's 0.3 calories per mile per lbs of body weight. Or roughly 0.41 per km per kg bodyweight. Yes, it's not a lot. But walking on two feet is our primary mode of motion. Of course calorie burn for that is fairly low, as is walking on four feed for most other mammals.

    My values are from Fitbit + data on losing as expected based on CICO. The equation referenced is flat ground, not incline. That equation indicates I burn about 2.6 cals per minute walking (flat) 4 mph. My actual net is about twice that, again supported by weight loss data. (Though again, my actual does include some incline but not enough to make up for the vast difference.)

    But in general, for someone who has no method to evaluate a burn rate, it would be wise to assume a low # until they have data to indicate otherwise.

    Thats what I'm thinking. My main form...pretty much my only form..of exercise is walking these days. I walk about 6 miles a day, and I know I'm burning more than 180 calories because I lose 1 lb a week on 1800 - 2000 calories, when my base number for sedentary is 1350. (179lb, 5'5" for reference). Outside of that walking, I'm pretty much a slug. Lol

    Typo. Per 100.

    Weight in pounds X .3 X distance in miles. 100 lbs x .3 x 1 mile = 30 ... Syracuse University study published several years ago in Runner's World. (179 X .3 X 6 = 322, not 180)

    Burning 200 net calories per half hour from walking requires either moving a lot of weight at a brisk pace, moving at a faster than walking pace, or going up a steep incline.

    Yes, my outdoor walking burns very little. Hiking a lot more due to challenging terrain and elevation changes.

    Indoors on my treadmill, I set it to 3.4 mph with an incline of 10. Sometimes I do hill mode instead, but if I’m short on time and just want some extra calories for a snack, the higher overall incline is the way to go.

    As sijomial says, weight loss results as expected don't confirm the accuracy of a specific exercise calorie estimating formula. Weight loss results that are as expected confirm that a person has dialed in a workable calorie level given the accuracy of their food logging, and the totality of their activity level; and they've gained strategies they personally can use moving forward.

    To use an intentionally and clearly absurd example: I barely walk at all (very sedentary outside of non-walking exercise), but will predictably lose about a pound a month on 1850 net calories. Since MFP predicts I'd maintain at around 1500, the implication could be that not-walking burns at least 475 calories per day (350 discrepancy from "maintenance" calories, plus 125 calorie deficit). Pretty sure it doesn't. 😆 Doesn't matter, my weight behaves as expected. That doesn't generalize to others who are 5'5", 125 pounds, sedentary, age 65. Waaaay doesn't.

    This is not to minimize the accomplishment of people who've figured out a personal equation (approximation) that works: That's absolutely the goal for all of us. It's perfect, in fact. But it doesn't necessarily generalize to other people.

    Where available, using research-derived formulas or other estimating methods is a more generalizable idea, and even that isn't perfect. It's useful to understand the ways in which an individual person may not have the same results as the averages derived from the research, too.
