What am I doing wrong?

Keep in mind that it takes your body 2-4 weeks for it to adjust to changes in your diet. Don't freak out and don't give up. Your weight will flucuate (naturally) within a 5 lb range.

Make sure you are getting activity in (walking is a great exercise!)
Make sure you are hitting your macronutrients (fat, carbs and protein)
Make sure you are drinking H20
Make sure you are eating over your BMR and eating back your exercise calories (If you are following MFP Guidelines)

So if my BRM is like 1921, I need to eat MORE than that in a day?

Also just figured out I've been drinking far too little water! I was doing the 8-10 glasses a day. Come to find I need closer to 15!

I disagree with eating back all your exercise calories. I think you need to eat your BRM and try NOT to eat your exercise calories. If you eat your BRM and then exercise 500 calories a day, that adds up to a weight loss of one pound a week. Eating your BRM and all your exercise calories adds up to NO weight loss a week.

Also, re-calculate your BRM based on your current weight.

From the looks of your diary, on most days I don't think you are eating enough.

Do you mean "BMR" ...basal metabolic rate?

Unless you are completely sedentary, never moving all day at all... I don't think you are supposed to only eat just your Basal Metabolic Rate (assuming that's what you mean by "BRM"). Your BMR is "The rate at which the body uses energy while at rest to keep vital functions going," which is basically the very minimum amount of calories you need in order for your body to survive and function properly if it were at rest all day.

My BMR is about 1400 calories. I burn an average of 600 calories a day through exercise, and another estimated 300 just living my life on the go and walking around etc. This means in order to have enough calories for one day and maintain my weight, I'd need to eat 2,300 calories. So, in order to give myself a 500-calorie deficit every day (to make sure I lose a pound a week and not slow down my metabolism while I'm at it), I eat 1800 calories to account for exercise and also allow for a caloric deficit to lose weight.

The proof is in the results: I am shedding a pound or more weekly.

If you are not going to burn a huge amount of calories a day, I do not see this being an issue. Fit people like to think it is the same for over weight people, and/or Obese people. It is NOT. The proof is in the pudding? Yes, the proof is in the pudding... Look at my ticker. I have been Obese, and am still overweight. I DO NOT eat back my exercise calories unless I have to. I have to if I need to hit my protein mark, OR if there is a HUGE deficit of calories.
