    Hey, Paleobird - Are you a believer now? (sorry, couldn't resist)

    "Humans, even those living in cold climates, are rarely exposed to the cold weather. They sleep in heated homes, drive in heated cars, shop in heated department stores, and bundle up with multiple layers for those fleeting moments spent outdoors. It’s even been proposed that the advent of central heating is related to obesity. I suspect that the total amount of human BAT also depends on chronic exposure to cold, especially since one study (PDF) showed that outdoor workers have more BAT than indoor workers. Acute exposure activates, chronic exposure creates." - Mark Sisson
    OK, OK. But Mark points out a couple of interesting things in that article while all the time using phrases such as "I suspect" and "It couldn't hurt to give it a try". I thought it was important that he pointed out the exercise component.

    "All this revolves around the activation of existing brown adipose tissue. While that’s important, what about creating new BAT? There are two candidates – chronic cold exposure and exercise.

    Irisin, the “exercise hormone,” appears to convert white adipose tissue to brown adipose tissue. As irisin increases in a rodent’s blood, energy expenditure increases without an increase in movement or food intake, suggesting an increase in thermogenesis mediated by the converted WAT. Humans also make irisin in response to exercise, so this could work for us, too."

    Perhaps this is why Tim Ferris' plan seems to work so well for some people. It combines exercise and spot CT to the neck area.

    Also the temperatures Mark mentioned were much less extreme. He was talking about 61 degrees, not ice baths. More is not always better.

    I can see all the benefits of CT, in terms of BAT and increased caloric expenditure. But I don't see why that would be the only thing that could break a weight loss plateau for some people? Diet and exercise shifts should be all that is necessary to bust plateaus, and, dare I say without referencing a study, have to be more effective than spot CT. Did you guys try varying the intensity of exercise routines (sometimes too much = plateau, so resting more can help. Sometimes not intense enough = plateau, etc.)? How about carb refeeds ala Leangains - I feel that'd be a great way to actually reset Leptin, as Martin properly references his studies about the carb/leptin relationship and how the cyclic, inverse relationship between carbs and fats can help for further weight loss as insulin-sensitive primal individuals may have poor leptin levels. Intermittent fasting is also a must. See: Intermittent Fasting, Set-Point and Leptin | Intermittent fasting diet for fat loss, muscle gain and health
    Martin Berkhan – Scorch Through Your Fat Loss Plateau | Fitness Black Book

    In terms of my "Guru Go-To List" I'd say listen to Sisson, then Martin, then Kruse if all else fails. It is wonderful that CT has worked, but make sure to try some of the more substantiated plateau-destroying techniques (especially if you're a wimp vs. the cold like me :P). Best of luck!

    The BO seems to have passed, which is good news. The experiment I'm going to try today is to ice my legs, take a cold shower, and then go to the gym a couple of hours later - I'm curious to see how my performance in the gym is. I have not eaten many carbs in the past few days, which normally means that leg presses are significantly harder. Actually, now that I think about it, the past few days - since I started icing and cold showering - I've been eating relatively little because my appetite has been low. I attributed this to the heat wave we had, but this seems a little funny since I keep hearing about how CT ramps up hunger. Maybe for me, it's a delayed effect!

    I do notice that my skin is looking tighter - which I didn't expect, because I figured that would be a temporary effect that only lasts a few minutes after the cold shower, but my skin seems to be maintaining the tightness throughout the day.

    Thanks for the responses to my questions - I feel much more reassured now!

    MamaGrok - you mentioned using activated charcoal to help with the detox effects. I have some that I bought last year, but I rarely use it because I've read conflicting things about it blocking the nutrition from the food you've eaten. Another website just says to take it 2 hours away from meals. Do you have any suggestions for how much/how close to meals to take activated charcoal?

    Otzi, your response about cold baths reducing the inflammatory effects of the fat cell death made a lot of sense. I don't have a bathtub in my apartment, but I will be able to use my in-lasws tub when visiting them this summer, so I'll try the cold baths then.The ice water baths you take got me thinking about something else... If you submerged your whole body (up to your neck/shoulders), this would likely lead to apoptosis all over your body, not just in targeted areas, right? But what if you didn't want to lose fat in the upper part of your body, only in the lower part? Over time, would this make you look too skinny in places where there was relatively little fat to begin with (arms, collarbone area)? I like the idea of a full body ice bath immersion, but this idea popped into my head.

    BB, I only have experience using activated charcoal on an as-needed basis, and because that's not often, I don't worry about meal absorption, but do take it away from meals, anyway, just b/c that seemed to make sense. I'd look up more about ti before using it as a regular part of your regimen.

    All-over ice baths don't really spot-reduce the way spot icing does, b/c it's much warmer, I think. I haven't had any problem with losing where I didn't want to, and haven't heard of anyone else having that problem, either.

    It is time to put down the Kool-aid. Mark didn't say anything about temperature for CT. The study he cited used 61 degree temps. As far as I can tell Mark has little to no personal experience with CT. Mark did some reading pulled some studies and put together a well thought out blog post that has no real world results in it. Take it as some good source information but the article was little more then that.

    On this topic you have no idea if more is not better.

    try 32F water. it should still be under 40F when you get out.

    Have you noticed that the people selling CT always say to keep the water in the 50-80 degree range? I think this is because they don't want to be held liable for killing someone with hypothermia. While hypothermia is a very real concern with 32 degree water, it can be done with great success if one adapts to it and doesn't go it alone.

    Wim Hof, the Dutch Iceman who started this all, packs himself in ice, swims under the ice on lakes, and runs barefoot in the snow. He can't very well say 'use 60 degree water' when everyone sees him in freezing water.

    32 degree water is definitely a different animal and I have seen whole-body apoptosis from it. I don't think one would become an unsightly freak if they just iced their legs, because it isn't like it will get rid of every single fat cell exposed to cold water. Also, I hope no one takes this to mean that a single dip in 32 degree water is a substitute for liposuction.

    I worked my way down to 32 degree water over several months, I think anyone who is doing the cold baths needs to experience 32 degree water. Even if it's just standing in a bucket full of it. It is a world of difference from 60 degree water.

    How long did it take you to go from, say 50 degree water, down to 32-35 degrees? I’d like to gauge my progress, make sure I’m not pushing myself too hard.

    I’ve been trying CT for almost 3 weeks, in the 52 degrees/30-40 minutes range. I made the jump a couple of days ago to 45 degrees/40 minutes.

    I thought 7 degrees colder would be no big deal, but it is huge.

    My reasoning for training afterward is just experimental. I stumbled upon it, like I've posted, after casually picking up some weights about 10 minutes after a CT session (enough time to get out of the tub, let myself air dry and walk downstairs). I picked up the weights and just felt "stronger." I did a few sets of exercises that I generally know my maximum capacity (push-ups) and was able to sustain the exercise with more endurance (in this case, 45 straight push-ups when generally I'm around 35 until failure). This was a big difference in something you don't normally see strength gains with that big of a margin. That is why I have continued these N=1 experiments.

    To really take it seriously, I need to take better record of maximum capacity on certain lifts to failure both before and after CT, and control for factors such as the time of the CT and meals consumed prior. I usually take coconut oil, MCT oil and a high dose of fat before CT, which does cause a thermogenic response but might also contribute to better performance from the direct energy from MCT's post-CT. I ignored this factor at the beginning because I usually use MCT's in some form as a pre-workout, but again, this is very loosely controlled.

    I'd love to see others try this though because I really do think there is a window after CT where I am capable of more work output in the weightroom. If this can be used for additional health benefits in-terms of gaining muscle or getting stronger, a lot more people would be willing to undertake CT.
