Just wanted to let you & everyone know the amount of calories burned in 30 minutes walking is 100 & that it is not accurate on here so when you walk a half hour just keep track how long you walk & remember you burn 100 calories every 30 minutes at 3 mph. It says in 90 minutes I burned 558 calories when I only did 300 calories. If you do not adjust this your not going to lose weight very easy.

I just go by the amount of calories my HRM tells me that I did....more accurate that way.....

Everyone's different, I burn 127 apparently.

Cals burned is different for everyone, as weight, and fitness level play a large roll. Not sure where you came up with the 300 cals in 30 min at 3mph calc.

Hiya :)

It depends on the weight you are...

The more you weigh the more calories you burn and then you get someone who has / is losing weight wondering why they are not burning as much as they used to...

Yep, depends on your current weight, mine does come up as 100 in 30 minutes at 3mph.

Cal burn is different for everybody based on weight and fitness level.

Keep in mind, a HRM might not be that accurate for walking because it's not a very intense activity, unless of course you're a speed walker averaging 4.5 MPH.

The other question is How do you know how fast you are going? Leisurely to one person might be slow to another? Anyone any idea? I tend to use the slower speed estimates and not eat all the exercise calories back and its working because I'm losing about 1lb a week which was my goal. I do a lot of walking but don't have a HRM

Sigh...

People burn different amounts of calories depending on their weight, effort and the terrine they are walking on.
You saying that is just as inaccurate as the "MFP calculations and the machines at the gym".

I hope this doesn't hurt anyone's feeling but they are NOT right. Thinking that you burned 1200 calories in an hour by walking fast on a treadmill is so unlikely. Most people would have to be running at like 8mph to get that sort of burn. I get it, some athletes can burn that. If sweat is not pouring down your face and your HR doesn't say at least 165+ you prob are not...

Wanna know how bad it was for me? For every 1000 calories the elliptical said I burned I only burned 600 with an HRM, the treadmill...only 500 out of 1000. MFP...said I burned 848 and hour...when I only burned 500-600.

Want an accurate reading?...get an HRM with a chest strap. The Polar series are wonderful.

Just saying.

You need to know the time and distance walked to work out the speed i.e 2 miles in 30 mins = 4 mph as 30 goes into an hour twice you double the mile to get mph :)

your calories burned is always changing as your weight changes my MFP numbers my HRM and both my treadmills are within 15 calories per half hour
when I was 367 pounds I could burn almost 750 calories per hour at 3.5 mph now barely 500 closer to 4 mph because I am more fit my bpm has come down from 150 at 3.5 mph to 150 at almost 5 mph
so to say that as an absolute you burn x cals per time frame at x mph just isnt right

personally when I do my walking and running, I am on a treadmill so I set the speed.....doing it outside I would have no idea how to know, LOL

I time myself and know the lenth of my walk. I burn 173 in 40 mins thats at 3 mph.
July 4, 2012 5:19 AM
Maybe I'll have to get on a treadmill just to see how fast I walk :) All my walking done outside in all weathers!

when I am outside I use 2 Apps on my phone with gps tells me my speed distance and shows my route on a map
also has helped me get back to hotel etc when out for a run when away from home as it shows starting point and current location

how do you know how fast?
Well measure it, mapmyrun or bikehike, or a even gps apps.

There are several sources online that can help you calculate the distance traveled if you know your route. Search "calculate distance run" to find a few. For those on Facebook, I use "I just ran" and there is an option on there for determining your route distance.

If I know my distance, I usually ESTIMATE about 100 calories per mile, to get an idea if what MFP or other sources are telling me are accurate.

For knowing how fast I walk I cheat! I look up my route on GoogleMaps and find out how many miles I've walked and then work out how fast I was walking based on how long it took me to get there. I don't think there is a definate way to know how many calories a walk burns but I have found that using the MFP calculations has worked for me, I have lost 7lb and wouldn't have if they were too far out as walking is my main excercise.

It just takes a little extra math to figure it out for outside. You need to know the distance traveled (aka, from home to the RedBox movie rental machine is one mile each way) and then pay attention to your start and end time (aka, if I'm gone 35 minutes, and five minutes was spent surfing the video options, then I know that I did about two miles at fifteen minutes each, at a pace of four miles per hour).
