Hi Tatey:
I have the newer version, PPLP, with the minimum protein requirements chart. Based on your height and weight, the chart indicates that your minimum protein intake per meal should be 30 grams. The absolute minimum on their chart is 20 grams, for a 5 ', 100 pound woman.
Given that the newer PPLP chart is based on
above-average activity levels and
average body-fat percentages, the PP calculations chart that you have is more accurate. However, you'll have to remember to recalculate your minimum requirements if you change any of the variables you used to calculate it (ie. your lean body mass or activity level). They made it easier with the new PPLP chart to pretty much guarantee that you will always have adequate protein.
Bottom line, if you use the 19 grams/meal calculation, it will have to be recalculated as you lose significant weight or increase excercise. If you use 30 grams/meal, no need to re-calculate.
One other thing, my requirements are 23 grams/meal for PP and 27 grams/meal for PPLP, which isn't really a significant difference. Is it possible that your calculations are off because there's a big difference between 19 and 30 grams/meal. Have you double checked your calculations?
Just some food (or protein
) for thought!
