So, I haven't been the best in the past couple of weeks when it comes to nutrition. So, I picked this last Monday (memorial day) as my clean slate day. The day I would officially "start over" in my journey. I even went out on Sunday and bought a new scale that not only tells you your weight to the nearest ounce, but also calculates your BMI, BMR, water %, and body fat %. It does not, however, do the dishes or the laundry. I checked.
So, I woke up bright and early Monday morning. I took my measurements and jotted them down in my journal. Then I, excitedly and nervously, weighed myself. I had gone up in weight, which was not a surprise at all. I figure it's all part of the journey.
But what I was surprised by (and incredibly disappointed in) was my BMR reading. Your BMR is essentially the base line amount of calories you need to live. The higher your BMR, the more calories you need to eat during the day. A good rule of thumb is to take your BMR and subtract calories accordingly to determine your weight loss calorie intake. For example, if you want to lose 1 lb. a week, you would subtract 500 calories from your BMR reading.
I had calculated my BMR using the various equations textbooks and websites provide. They all came out to a nice round figure between 2200 and 2600. WOO HOOO! If I wanted to lose weight, I just had to subtract 1000 calories/day (for 2 lbs/wk). No problem, right. I can live on 1200-1600 calories! That's doable!
However, according to my fancy-dancy scale, my BMR is 1600! MY BASELINE TO LIVE is only 1600 calories!! That means I don't need very many calories to live. That also means that the MOST I can cut my calories is by 400 (.8 lbs/wk). (all of this is not taking exercise into account as my daily exercise amounts vary).
1200 calories is not enough. 1200 calories sucks. i'm starving. when I enter my daily food, I'm always surprised to see how little calories I have left over after every meal. I'm eating 400 calories/meal (roughly) - which does not allow for snacks. hungry hungry jenn!!!!
so, I'm frustrated because my BMR sucks. Additionally, I've read that although exercise can slighly increase your BMR (through the development of lean muscle tissue), it's not a large increase. So, now I know I can't really do anything to increase my BMR. I'll be destined to exercise like a crazy banshee and eat like a bird the rest of my life.
