This week I just finished up phase II of a calcium / osteoporosis cycling study. I participated in it last year and for all 4 of my rides I was required to eat this not so keto breakfast 3.5 hours before riding. Thankfully I didn't have to eat it before my VO2 max rides.
Oatmeal 35g, Whey Protein Powder 12g, Rasins 9g, Walnuts 10g, Brown Sugar 3g, Eggbeaters 95g, Canola Oil 6g, Baked Potato 125g, Butter 4g, OJ
The procedure was a 1 hour ride at 70% power of max power at VO2max. Then 4 hours of fasting. I ate my potatos cold in an attempt to get a little RS into the diet and was well back into ketosis after the fasting.
While results are preliminary it appears that cycling uses up an enormous amount of calcium for muscle contraction.
Lots of other lab tests were run including a DEXA scan. Here are some of the results.
Differences from last year:
BF% 8%-> 14%
Bone Density Hip 0.2 -> -0.4
Bone Density Spine -0.6 -> -0.2
VO2max absolute 3.74->3.64
VO2max relative 56.9->48.1
Max Watts 250->275
Max HR 186->178
TSH 2.89 -> 1.1
Serum Calcium no change
Vit D no change
It's a little depressing that my only cheat meals in the last 2.5 years of keto have been hospital food.
