Net calories

Your numbers seem a bit off to me. Outside of exercise, are you very active in your everyday life, or do you work a desk job? For a sedentary person of your height and weight, MFP estimates 1480 net calories per day to maintain your weight, and 1230 net to lose .5 lb per week

What do you do to burn 500 calories per hour at your size? One of my tougher workouts estimates 377 calories per hour for your age/size and even then I would tend to adjust it downwards and not eat back all the exercise calories

Using those numbers as an example, say you ate 3500 calories and worked out for two hours. Your deficit would be:

1480 + (2 * 377) - 3500 = -1266. Multiply that by 7, and divide that by 3500 calories/pound and you'd gain ~2.5 lbs per week

Now that we have that sorted out, yes net calories work. Tons of us have used the concept to lose weight

105 seems like it may be a healthy weight for your height. Is there any chance you may wish to concentrate on fat loss and maybe some muscle building rather than further weight loss?

1000 seems quite high number for your height and weight. I would buy good HRM to be sure. Everything above 100 calories per 10 minutes is almost for sure error.

By mine experience fitness equipment is least accurate, then MFP and last HRM which tends to be the most accurate.

I hardly want to lose any, just a few vanity lbs and to stay in the healthy range! I burn over 1000 on the treadmill every day.

You're running 15 miles every day on the treadmill? If not, you're not burning 1000 cal...... ( .63 x weight in lbs x distance) if you're waling it would have to be closer to 30 miles.

You need to recheck your figures.
