My Nutritional Profile Analysis

I have come to a stand still in the weight loss area, so I hate to do this but I must dig into the details and figure out how to get my body to respond to burning fat so I can keep moving down the ladder to achieve my goal racing weight of 165 lbs by May 10. I started this weight loss initiative on November 24 at 188 lbs, presently I am hanging at around 182 lbs (6 lbs in 8 weeks, 0.75 lbs per week).

Ok lets get the details out:
  • Based on my age, height, and starting weight my Basil Metabolic Rate (BMR) is calculated to be around 1830 calories. Basically, that is the calories I need every day to ensure all systems are functioning properly....this does not include the calories needed for exercise;
  • As a rule if you are very active in the exercise area you should multiply your BMR by 1.5 to determine your daily caloric needs with exercise, so that brings me to 2745 calories.
  • Also, we know that on average for each person a caloric deficit of 3000 calories per week translates to 1 lb of fat loss per week.
  • So, if I have on average a caloric deficit of 500 calories per day i.e. consume 2245 calories per day I should see a weekly deficit of 3500 calories or ~ 1.2 lbs per week loss.
  • Not so fast spanky, as we loose weight we need to adjust because everything changes....remember our BMR and caloric needs with exercise are based on starting weight, this has changed it has lowered by 6 lbs so the 2245 calories per day being used today does not provide as large of a deficit....are you with me? Lets adjust for the new weight.
  • Based on age, height, and new weight of 182 lbs my BMR is 1791 calories per day and with the exercise multiplier it becomes 2685 calories per day. In order to achieve a caloric deficit of 500 calories per day my daily consumption should be around 2185 calories.
  • This seems pretty minor and maybe not a big reason for the slow down. But worth adjusting none the less.
  • Lets now examine my daily caloric intake. I used to log this daily to ensure I was on track, I have a funny feeling this is a problem and I will have to resort to this practice again.
  • For Saturday January 24 total calories consumed for the day 2500 calories - 60% carbohydrates, 22% protein, and 18% fat.
  • Wow! We have found the problem....eating to much...assuming this is pretty close to my daily average, which I would say is a little high but not far off, I would still lose weight but very slowly.
  • The macro nutrient profile is not bad, maybe slightly less carbs and more protein would be good.
  • Going forward I need to cut out that extra bowl of cereal, sandwich, and cookies at night.
  • If I do this, it gets me in the 2100 to 2200 calorie per day zone and adjusts the macro nutrient percentages to show slightly less carbs and more protein....seems simple enough.

Here's to getting back on track.
