26000 steps for me would be about 10.5 miles (I test it against various treadmill mileage counts every so often) - I don't think the calorie burn is that far off, actually.

Thanks guys xx :bigsmile:0

I just can't even
and that's just after reading the OP
I assume the actual advice has been covered off0 -
From what I've heard now, exercise seems to only count for about half of what it's truly logged in to MFP as.
I think it's very individual. I've heard this a lot on the boards, but in my experience, and the reports from some people on my friends list has been that when I did start using an HRM I found that the MFP numbers actually weren't too far off.0 -

4 hours of exercise could definitely result in a 1400 calorie lost. She's only burning 350 calories an hour. I use a Polar fit hrm and can burn over 1,000 in 2 hours if I do two high intense cardio classes at my gym back to back. I don't dare try to do this every day, I wouldn't be able to sustain it. But it's possible. I personally wouldn't work out for 4 hours but her scenario could be a true issue.0 -

OP said they really do 4 continuous hours of high intensity work. So maybe. I was just skeptical that anyone could do that much work at that high intensity for that long. Idk.

People have fast days for various reasons so, of course it's possible. Is it sustainable? No.0

I occasionally have this happen on a Sunday when I tend to do a long bike ride (road cycling - vigorous effort) and then come home and do a lot of gardening. I eat around 1500 cals but burn around 1700 so end up -200. This is not sustainable on a regular basis though... As long as you feel fine and are eating a healthy balanced diet you will be fine just not EVERYDAY!!!0

I think it's certainly possible to do it on occasion (or at least moderate intensity sufficient to burn 1400 calories). I mean, people run marathons, go for day long hikes, climb mountains, do century rides, etc.
What I found problematic about the OP was whether it was possible/sustainable to do that every day while eating so few calories. Or whether it's realistic to do 4 hours of somewhat intense exercise a day (although people who have active jobs probably do something similar or more--they simply don't eat 1200 calories while doing it, if they are smart).
So for the record, no.
(I also think it's easy to overestimate swimming calories, since the higher calorie entries are for a kind of swimming that most people who just swim recreationally and don't have some kind of competitive swimming background probably don't do, and it's easy to ignore time out for stops. But this is simply why I used to cut my swimming calories way down before I switched to TDEE. Also, I'm another who gets quite hungry from swimming!)0 -

That's funny, after high school swim practice we'd always go get DQ Blizzards. Only in Minnesota do you see kids with wet hair in freezing temperatures eating ice cream outside lol.0 -

I suppose it could happen every once in a blue moon but I would not do it on purpose. You could eventually get dietary deficiencies, lose hair, etc.0

Huh. I can honestly say that I've never gone into the negative. Definitely doesn't seem like a good idea to do it often.0

I'm about 5'8" and 205 pounds if that helps at all. Thank you to everyone for informing me!
Similar size here, and I have logged many 900-1400 calorie burn days... mostly from running and coaching. Tangent: You know there is a downside of weight loss? Burn rate drops for same apparent performance. It's a good problem to have. ;-)
Since I'm totally new to input calorie counting I can't say I've ever gone negative. This past week was net ~300 twice. I might be underestimating input by at times, but cals from exercise I feel confident about as I use a HRM and it's easy to expect a 10k to burn 800-900+ for my weight and pace, and I often have multi sport/activity days.
I'd not be too concerned about going negative once in awhile, as your fat stores are stores of energy after all.
I let my body tell me what to do. If its been, or will be, a big exercise effort day, I will be eating appropriately more, and I didn't need to count calories to know or do that.0 -

I have a really hard time believing you burned 1400 calories in one day, unless your session was like five hours long.
a lot of people overestimate their calories burned...lol so i agree with you.
Also, it can really depend on the type of exercise and how rigorous the training was.
Moreover, calories burned are just estimates...so I don't really focus on calories burned after exercise...
That's a problem here on the MFP app. I run on the elliptical for an hour and the machine at the gym tells me roughly 900 calories. That can't be right. Then MFP tells me that 1185 calories burned. WHAT? At the average of 5 calories per minute, that's only 300. There's a lot of discrepancies on both this app and the machines at the gym, so I never really know what I'm burning.0 -

That was on an 9-hour (moving time), 111.5-mile bike ride up and down the Berkshire Hills of western Massachusetts. I just couldn't eat that much.
You're my new hero. I just got into cycling and only aspire to do that much! My fiance is a cycling freak, and I don't know if he could even do that ride. Wow.
Aw, shucks! It was the Great River Ride out of Westfield, Mass., following the three branches of the Westfield River. Absolutely beautiful scenery, with the foliage at its height.
If you're in good health and have patience, you can work up to a ride like that. It's mostly about three things: (1) building the endurance to exert yourself at a moderate level all day, (2) learning how to eat and drink enough calories on the bike (200-300 calories/hour) to keep your blood sugar up and prevent a bonk, and (3) accustoming your butt, feet, arms, hands, and neck to spending that much time on a bike!0 -
Yes, if you're fasting or starving yourself for a long enough period of time. Of course something I don't advise to do.

Cardio machines also grossly over estimate. 60 minutes on the Pre-Cor elliptical and the machine (after inputting gender, age and weight) will tell me I've burned a little over 700, while the HRM says I've burned about 450.0
