I wrote about my experience with cold showers here before: https://news.ycombinator.com/item?id=8808859 https://news.ycombinator.com/item?id=8808859 490 days later, I'm still using cold water only. Except for ears: switched to using warm water when experienced some buzzing in one ear during last winter. I've upped my game by adding snow/ice baths during the winter. Since last autumn I have added daily HIIT - 10-15 mins of advanced body-weight exercises with 20 sec. rest intervals. Now, how it affects my weight. Since the last time I wrote about it, I've actually begun to follow my weight numbers. Back at the time I was about 84kg. Cold showers alone, with some gym here and there didn't do much for weight: it went down to 83 sometimes, but bounced back to 84 later. Yet, I must say, I was well into the practice by that time, and few years before I could weight as high as 88 kgs. So, perhaps, cold showers did lower my weight somewhat without my notice. Adding HIIT gave a steady weight loss, albeit a slow one: three months into I lost only 2-3kgs. It is possible that HIIT burned more fat yet balanced weight by adding lean mass: some muscles are bigger now. Mind you, all that time weight was of no concern to me: followed it just out of curiosity. Last January though, my old trauma reminded about itself and I needed to lose weight. Since I was already doing most of the recommended stuff, I just cut on calories by completely removing sugar and keeping 12 hour window for eating. In one month I lost about 6kgs going to 76-77kgs and decided to keep it their by increasing calories. TL;DR: Cutting calories is the fastest way to lose weight, neither cold-showers, nor HIIT can compete with it in short term. On the upside, both cold showers and HIIT are downright pleasure to do once you get addicted to them. I do HIIT after the work before evening meal, at about 5 - 6PM, follow it with a cold shower and feel full and energetic as if I've just waken up in the morning.
