Ok, so bare with me on these calculations.

I am 5'11" 180# 26 yo. male. A BMR calculator indicates that my current BMR should be approximately 1,800 to 1,900 kcal a day. From what I know BMR is while rest. This means it doesn't account for the extra activity of walking, taking a shower, thinking etc. that burns some calories too.

This is my plan then:

Daily food intake - 1,500 - 1,600 kcal.
average daily kcal burnt while cycling - 500
Miscellaneous calories burnt a day - 150

So if I do the above:

BMR = 1800
- food intake = 1500
+ Cycling cal burnt = 500
+ misc. cals burnt = 150
= Calorie deficit of 950 kcal a day.

950kcal * 7 days = 6650 / 3500 = 1.9 pounds a week.

Is this a healthy way to lose weight? I seem to be stuck at 15% BF and 179 pounds.

Does one burn more than the BMR on a typical day? Does the BMR change based on current weight?

Thanks,
Luis
