This is an update to my January 2016 discussion. See details there about goals and habits.
WOW: look at the plummeting weight (green line). Weight as of 17 June is 2 pounds lower on the same date as my ultra-lean year of 2011/2012, where I reached 7.9% body fat as per DEXA scan. I’m not at 8% yet, but maybe I’ll get there.
Starting with the Davis Double on 21 May, I took one day off, then I entered into a 10-day aggressive calorie burning program of about 1400 calories per day with 2+ hour rides at low/moderate intensity. This was an extreme load: about 14000 calories burned (4800 calorie deficit) in 10 days on top of a 6600 calorie deficit from the Davis Double.
Next, I did the Eastern Sierra Double Century on 4 June for a calorie deficit of ~5000 calories. The next day I did a 14-mile 4000 vertical foot hike for “recovery”, so probably another 1000 calorie deficit. The following days more hiking at high altitude.
- I’ve stayed away from grains (mostly), the exceptions being Panda licorice during double centuries and rice as part of sushi before double centuries. Otherwise, no wheat/rice/corn for a couple of months now (a few minor exceptions).
- I noticed that I had something like 6 of 10 or so symptoms of iodine deficiency (non symptomatic as in goiter, but nonetheless having many health effects). I read that iodine is lost through exercise (and I excercise vigorously at least 90 minutes every day). Things clicked: I started eating sheets of seaweed nori @AMAZON, taking kelp tablets @AMAZON. IMO, the RDA of iodine is probably far too low.
- I started taking 25,000 IU Vitamin D3 @AMAZON.
As shown below, body weight has plummeted sharply (meaning body FAT). My TSH has been borderline (low) for some years as has my Vitamin D (even in summer). Those two factors figure in as likely candidates, but seasonality may play a role; my body has always responded to the mid-May/mid-October seasonal cycle in weight loss/gain.
The 174-pound mark at right was reached after Davis Double and the following 10-day efforts. The 171.6 mark was seen after returning from the mountains after the Eastern Sierra Double.
