Does the treadmill have a cardio or fat burn option? You could try that and you can usually enter your age, weight, and target heart rate. You should also be able to set the level you want to work out on. The treadmill will ask for you to put your hands on the heart sensors every 30-75 seconds.
Hope this helps. If you're not seeing the results you want you can always try mixing up your routine - try the tandem bike, the elliptical, or go for a walk out and about.
A very ROUGH guide is that you burn about 100 calories per mile walked (a little less than this for lighter people). Either the treadmill or Spark is feasible for 1.5 miles walked. The 279 figure is not realistic.
It is a common response when you start/increase an exercise program for your muscles to retain water. This increase in your lean mass can lead to little change (or even an increase) in the scale even as you are burning fat. But water and muscle are considerably denser than fat, and typically this shows up as inches lost, even if the scale is being unco-operative. If you are losing inches, you ARE burning fat.
You should buy and wear a Heart Rate Monitor. That will give you the most realistic indication.
For 30 minutes at that speed, at your weight, probably the lowest figure. Spark's fitness tracker is pretty reliable for walking/running as they are well studied. That is a slow walk (sorry if it feels fast to you - you may have some work to do) and you just don't burn much with that.
Most exercise will be 6-8 cals per minute (cpm). Those values for 30 minutes would equate to:
3.6cpm 5.6cpm 9.3cpm
I would go with either of the lower two, the middle one is kind of pushing it though. I would have thought somewhere between those two most likely.
Why are you eating so low? At your weight you have very little weight to lose (if any) and should be aiming for half a pound lost per week. That would normally put most people in the 1600-1800 or so intake range, depending on exercise. You just aren't fat enough to eat that low.
If you're having difficulty losing, it's probably because you're not eating enough.

I usually do not worry about calorie burn because I thought I am burning enough calories to lose weight. I have been sticking in 1200 to 1500 calories intake also. I still did not see much result in weight lose in scale but my clothes are fitting well and I am feeling some weight lose but my scale gives me same old numbers. So now it is time to look closely.
My question is which calorie burn is accurate on 30 min on treadmill with 3.0 MPH
