hi all, I have been using mfp for a few weeks,

I have been reading so much on the forums that I am actually confused and I'm not sure what to follow.

so first, this is what I put into fat2fit bmr calculator
Custom BMR Calculation
Thanks for checking your BMR here on Fat 2 Fit Radio. If you're not already subscribed to Fat 2 Fit Radio, consider doing so today. Please visit the Subscribe page to get the podcast delivered automatically to your iTunes, Juice, e-mail inbox or the podcatcher of your choice for FREE.

Entered information: 33 year old female, 62 inches tall, weighing 119 pounds, BMI of 21.8 (Normal weight).

From the information that you entered, you'd like to weigh 115 lbs.

Harris-Benedict Formula
There are a few different methods to calculating your basal metabolic rate (BMR). One of the most popular, developed in the early 1900's is called the Harris-Benedict formula. Based on this formula, your current BMR is 1309 calories.

How Many Calories Should I Eat?
Based on your goal weight, the following chart was generated. The chart shows the number of calories that you should eat on a daily basis to reach your goal weight. At Fat 2 Fit Radio we advocate eating like the thin, healthy person that you want to become. The calorie levels you see in the chart are not extreme, but they do create that all important caloric deficit that is required to get you to your goal weight in a safe manner. Once you reach your goal weight, you will continue eating the same number of calories for the rest of your life to maintain that weight. You'll never be on a diet again.

Based on how much activity you do on an average day, the calories in the right column will be the number of calories that you will be able to eat at your goal weight. If you start eating those calories right now (eating like the thinner you), you will eventually become that thinner person. As you get closer to your goal weight, your weight loss will start to slow down. It is OK to eat a few hundred calories less per day (200-300) to speed up your weight loss at this point.

Activity Level Daily Calories
Sedentary (little or no exercise, desk job) 1550

additionally I use fitbit. right now everything is set to my calories at 1300, and mfp says on a regular sedentary day I should burn about 1500, which matches the above number. I set my activity level to sedentary b/c it could be different day to day so I would rather have fitbit calculate the extra calories that I burn to be more accurate. while my job is a desk job, about 3-4 days a week I walk 1.8miles to work, walk 30mins on my lunch back, and walk back 1.8miles home @ a moderate to fast pace. I also work out 5-6 days a week.. whether it be rock climbing gym, running or biking. I do not enter in any weight / core exercises that I do.

so my main question is, if I wanted to lose .5 to a lb a week, do I still eat 1300 calories a day no matter what my activity level is, or should I just make sure I have a deficit of 500 calories a day based on what I actually burn (which is usually more than 1550 calories.

I'm asking b/c I'm wondering if I'm doing something wrong. I haven't lost anything in two weeks but on average I have a calorie deficit of about 350 calories a day, which I know isn't enough for a lb a week but I actually gained a lb this week which I'm baffled about. I am pretty anal about measuring my food, and if I eat out, I will try to over estimate a little instead of underestimate. when I go to the rock climbing gym, I usually spend about 1.5-2hrs there but I log about 45mins to take into account the breaks.

any help? thank you!
