Does anyone have a thought about how accurate the readouts are on exercise machines? I'm giving myself credit for those calories so I can have a little more to eat! Thoughts??

    They aren't accurate. I'd say eat around 50-75% of them... I'd personally shoot for 50%.

    It depends on the machine. If it's asking you for gender, age and weight, it'll give you the burn for the average person of your gender, age and weight. That may or may not be the same as what you burn doing that activity for that intensity and duration. If it doesn't ask you for those things it might be even more inaccurate for you. I'd suggest entering only 50% of what the machine says to be safe. The other option would be to get a heart rate monitor which should be a little more accurate.

    Not accurate for me at all. 8 miles on an elliptical in 60 min at 18-20 resistance (20 is the max), the machine shows that I burn around 1,200-1,300 calories but my HRM shows only in 700 range. I usually record less than 600 and eat back maybe around 400-500 of that. All these numbers with my age, height, and weight entered into the machine.

    A lot are TERRIBLY inaccurate. Some of the cycles, especially, seem to give inflated numbers.

    This morning the elliptical gave me 700 calories for 1 hr, my Activity monitor gave me 454, I go by my activity monitor.

    Just try not eating the calories back and see if that helps

    I typically do 45 min of cardio which the machines I do say is about 540 calories and I put 500 into MFP. I end each day using every single calorie alloted. Which includes the 500. If I workout. I do this 3-4 x a week

    You have to take in less than you burn to loose weight. You will maintain your present weight or gain if the equipment is over estimating your calorie burn.

    I'm definitely not doing this right. I thought that the number mfp gave me plus any exercise would be the number I need each week to lose 1 pd. Since I can't get an accurate number for calories burned this is going to be soo much harder. I work out to get extra calories so I can have a treat at the end of the day. :(

    You can still do that, just keep in mind that those exercise calories from machines or MFP are estimates and won't be 100% accurate. To make up for any inaccuracies, I agree with other posters on eating back 50-75% of those calories, most of the time (eating them all back every once in awhile is good for sanity sometimes too!). If you aren't finding the weight coming off after a month or so of eating back all of your exercise calories, it's a good sign that something is off in the numbers somewhere (either inaccurate food or inaccurate exercise calories).

    Good luck!

    The machines have ulterior goal to grossly overestimate the calories - they want to show you "look how many calories you burn on our equipment! We are better than XXXX".

    Additionally, you have to keep in mind other inaccuracies and try to eliminate the ones under your control: do you weight and measure all your foods? If you dont, that would be a more important issue to address than machines inaccuracies.

    You can do it without weight measuring your food if you're just honest about how much you eat, and count every calorie. Also do you move around a lot during the day. Do you track your activity away from the gym. Scales are great if you're eating at home all the time, but honestly how many people actually eat all their meals at home?

    Depends on the machine some are a lot better than others.

    Yes, you can, just not as effective. I could bet money that most of us would not estimate correctly 1 serving of spaghetti, or steak, or beans, or cereal, or baby back ribs - anything. I mean, you can think that you are honest about how much you eat, but it wouldn't be accurate as with the scale. Ultimately, you can go by your weight over time - if you are losing, then, obviously, you are at a deficit - but it's neither effective or accurate

    I do. The last time I ate out was in May, when my son visited.

    This thread has been really helpful. I'm going to keep exercising and will take 25% off the readout number and see if that will help. I have stated weighing my food but I do eat out frequently so there's alot of guessing. Its really hard. I just want to lose 10lbs!! Thanks to all

    I was able to loose weight before joining MFP didn't count any calories, just started doing that about 6 months ago, didn't change anything with my diet, just joined a gym and started really exercising and not just going through the motions. That was over 2 years ago, able to maintain my weight, recently got a scale and found out I was over estimating my calories. Now this will not work for everyone, just like you may eat all your meals at home, everyone doesn't. That's why I stated, be honest about what you eat.

    A lot of people are against these, but getting a HRM really helped me. I got one that I'm able to see my heart rate when doing cardio. (that's what I meant by going through the motions) I would get my heart rate up to 80%, in the beginning could only hold it there for 5 mins, now I can do 60 mins or more.

    I would second that - a dedicated HRM is invaluable for cardio workouts.
