Beautiful Sat evening, 65º and clear. After a day of auditions at MTSU, I did the Roark's Cove bike climb. I took it easy, about the same as last time, just a few seconds faster. I was hampered with a little abdominal pain, and I'm now 48 hrs into a 60 hr fast. This I think will be my longest.
Roark's cove bike climb
Total time - 25:19
Max HR - 183
HR over 170 - 4:51
HR over 180 - 0:25
Feeling pretty good, not really hungry. Not too sore after the stadium stairs. I'm quite a bit lighter than Thurs when I weighed 148. 141.9 after workout, and that's a bit deceiving as I still have the fat on my abdomen and back that wasn't there in Jan, its just that I'm empty. It'll take weeks to lose the extra few.
I had read that fasting 36-72 hours promotes cellular renewal and promotes autophagy benefits.
Who knows. Maybe I'll do it again. Interesting that even after a 48 hr fast, blood glucose is at 85. Thought it would be less.
Seeing the kidney Dr on Monday. I would like to start my collagen supplements again but not sure if I should. I really do think it helped.
Fasting==>rapid weight loss==>natural diuresis==>kidney stress/damage.
ReplyDeleteI would think it would stress the gut biome and clean the kidneys
DeleteKidneys are sensitive to dehydration. Chronic dehydration leads to nephron loss, shrinkage and GFR decline. Fasting increases risk of dehydration and electrolyte imbalances. Especially extended fasting.
DeleteIt could be that your borderline eGFR and mildly atrophied kidney is from years of weight obsession and chronic dehydration. Sauna, hot tub, not eating to end of day, striving for low body weight at end of day after late workout insufficient time to properly re hydrate. Fasting adds insult to injury.
DeleteOf course I wasn't fasting from water
DeleteThis comment shows you don’t understand. 30 percent of your liquids comes from food. The natural diuresis from a fast results in additional losses from the renal system. Electrolytes intake has shifted which renal system compensates. Hence dehydration risk. You would have to significantly up fluid intake, including balanced electrolytes, or take IV’s to prevent mild to moderate dehydration.
DeleteDrinking a liter a water upon waking everyday, then throughout the day. I will ask the renal specialist today about it
DeleteStick to a pre determined plan of good practise for exercise and nutrition. Random training and random eating is not beneficial.
