Week 3 - Cold Thermogenesis

Week 3!


This week we went on vacation. I spent 20 hours in a car. I ate road food and fried seafood. I didn't get to do almost any DDPYoga, but I did walk a damn lot, swam in a cold ocean, and played in the sand.


I brought my Cool Fat Burner vest with me, but I only used it once a day and it felt not quite as effective.

Criteria To Track

The following are purported results of cold therapy. Measuring some of these has been tricky.

Lowering Body Fat Percentage (measured with an electrical impedance body fat analyzer)
Week 0 - 17.1%  Weight On My Home Scale - 192lbs
Week 1 - 17.0%  Weight On My Home Scale - 190lbs

Week 2 - 17.3%  Weight On My Home Scale - 188lbs. That's weird, weight down, body fat up.
Week 3 - 16.9%  Weight On My Home Scale - 192lbs. Weird again.

*NOTE - The two devices I am using are not top-of-the-line contraptions. They are almost the opposite. For each of these I am taking the measurement multiple times until I get an average or consistent number. Week-to-week changes are likely not statistically significant. Comparing Week 1 to Week 8 will be the significant result.

Cutting Food Cravings
Week 1 - While wearing the vest at night, I have occasionally been snacking less. This snacking may be more habitual than hunger related.

Week 2 - No noticeable change in hunger.
Week 3 - Vacation week. Very little evening snacking. Felt fine.
Improving Deep Sleep Quality
Week 1 - I have not noticed an improvement in sleep. On some nights it has taken me longer to fall asleep, although this has not been consistent and is not necessarily related.

Week 2 - If anything my sleep has been worse. I do not think that this has to do with the cold. I've been reading The Dresden Files at night and it keeps me awake.
Week 3 - Vacation week. Really shitty hotel bed resulted in shitty sleeping. 

Increasing Pain Tolerance
Week 1 - Not sure how to measure this. Perhaps my cold tolerance has increased, but that may be speculation.

Week 2 - Still not sure how to measure. 
Week 3 - Vacation week. ?

Reducing Inflammation
Week 1- I do DDPYoga as an almost-daily exercise. Occasionally I have stiffness in a shoulder or lower back, both in areas where the vest does not come into contact. I have still had the occasional shoulder stiffness. I have not noticed the lower back stiffness, but that is not a daily or even weekly occurrence. 

Week 2 - I still have the occasional stiffness.
Week 3 - Vacation week. I had a sore butt/back from driving.

Week 2 Summary

Because the week was so weird, I think that all of the results are imperfect. However, if this week is back to normal, my body should rebound.
