The main thing is consistency and always listing everything that you eat. "You bite it, you write it."
It's OK to eat close to the BMR, you just don't want to go under it too far on average.
Remember, total daily calorie burn = BMR + activity level. From the total, you calculate your daily deficit target to lose weight.
Also keep in mind that these numbers are estimates, and you may have to adjust somewhat for your own use.
