Having a raised resting metabolic rate means you burn more calories, even while you sleep.
Do you know what your “RMR” is?
Do you know what being “Cold Adapted” means?
Guess what happens to your RMR when you’re Cold Adapted?
Resting Metabolism, aka your “resting metabolic rate” (RMR) is the sum total calories your body burns when completely at rest. The majority of these calories are burned by the organs; the brain, heart, liver, kidneys, and so on. They work 24/7, so it figures they would burn a lot of calories. For the average person, their organs may burn up to 70% of their daily RMR totals. Note that skeletal muscle has been estimated to burn ~ 8 cals/ lb/ day, while at rest. Even fat (regular white fat, or ‘WAT’) is estimated to burn around 3 cals/ lb /day. Most people don’t realize that even white fat burns some calories. Of course, Brown Fat (BAT) burns far, far more calories than WAT.
Even at rest your body burns calories…
Cold Adapted: when your body is used to regular cold exposure and has up-regulated its systems accordingly. Being Cold Adapted is the condition where you have reestablished a state of primal, ancestral health — lean body composition, proper hormonal balance, low inflammation, boosted immune system — as a result of a consistent practice of cold thermogenesis (CT).
Remember: our ancestors did not have constant indoor heating. Controlled temperatures are a modern invention. Humanity spent the first million years of our existence adapting to the environment, not controlling it.
Being cold adapted means you experience a state of primal health even on days when you don’t engage in cold thermogenesis! As with all things, you’ll need to engage in CT at least at maintenance levels, or you’ll eventually lose the effect.
This experiment was to determine weather being “cold adapted” can raise one’s resting metabolic rate.
As we saw in the introduction, the “Before” portion of the multi-part experiment involved reducing (and eventually stopping) CT, gaining weight, reducing cold adaptation,
so as to get a more baseline “normal person’s” level of cold adaptation and related RMR. (ie, someone who hasn’t done CT, and is far from being cold adapted)
There would be “Before” and “After” sets of tests.
Before: Fatten up, stop all Cool Fat Burner use. Lose cold adaptation, gain fat, monitor health markers. Measure resting calorie burning via indirect calorimetry.
After: For 8 weeks resume Cool Fat Burner use for a period long enough to re-gain cold adaptation and get re-tested.
Compare the ‘After’ results to the ‘Before’ numbers.
|The “Before” readings… Jan 16th.
|Low cold adaptation, fattened up to 210lbs, a RMR of 2074 cals/ day. The RMR rate considered slightly above “average.” [see Discussion as to why!]|
Following the “Before” readings extensive cold thermogenesis sessions commenced. Minimal session times would be at least 4 hours. Sessions were frequently 6-7 hours, and on occasional, go over 10 hours long! (Several clocked in at 12 hours long!)
|These sessions would usually involve 1-4 hours “High / Hardcore” intensity (interval shivering), 1-2 hours just below shivering (stereotypical BAT zone), then any number of hours lounging in the same room (shown to maintain BAT activity, via the BAT PET scan experiment).This would go on for 8 weeks, as part of the Body Recomposition component of the experiment; CT was the primary source of calorie burning and weight loss, as exercise would be used solely to preserve and build muscle; diet was varied, depending on the day (muscle building vs fat burning). (see “Body Recomp” video / blog for groundbreaking results!)|
|The “After” readings… March 16th. (8 weeks later)
|High cold adaptation, trimmed down to 195lbs, (see “Body Recomp” video) an RMR of 2477 cals/ day. An increase of 403 cals /day!!! The RMR rate considered “fast,” around 30% above normal.|
|The extended “After” readings… May 12th. (three weeks at maintenance, then 4 more weeks of Cool Fat Burner use after that)|
|Peak cold adaptation, (see Brown Fat PET scan experiment) leaned down to 194lbs, a RMR of 3125 cals/ day. An increase of 1051 cals /day from the ‘Before’ readings!!! The RMR rate considered “fast,” around 65% above normal!|
So reducing cold adaptation made it easier to gain fat. Though note that even in the “Before” readings, the RMR was slightly above average. Was this due to residual cold adaptation?
Perhaps some increased muscle mass (compared to average)? Engaging in intense, regular cold thermogenesis, and thus re-establishing cold adaptation, made fat loss faster and easier,
and apparently raised the resting metabolism, by a massive 1000 cals/ day. But these numbers seem too high. Is a person’s RMR really that flexible, and can cold adaptation really raise it that high?
And what exactly, physiologically, is responsible for that increase?
As mentioned in the video, there are several things possibly occurring here.
1. BAT was still active:
It’s already been shown in the BAT PET scan experiment, that the Cool Fat Burner can not only activate brown fat, but keep it active for long after the session ends, even in an environment that otherwise would not activate BAT. Cool Fat Burner users have reported increased sensations of heat, hours after their CFB session ended. CFB creator Eric G. comments that he has experienced increased heat generation sometimes as long as 16 hours after a session. It is very likely that there could have been BAT active during the next morning (10 am) indirect calorimetry test, if the Fat Burner / Gut Buster were used the night before. This also brings to mind the study on “constitutionally lean” woman who have active brown fat, 24 hours a day, even at room temperature. Eric G. could more or less be mimmicing that effect via cold adaptation, thus raising his basal metabolism.
2. “Accidental” cold thermogenesis:
When a person is cold adapted, they are comfortable in colder temperatures. What would feel cold for the non-cold adapted, feels normal and comfortable for those who are cold adapted. On the trip to both locations, there could have been “accidental” cold thermogenesis occurring. The “After” readings (March 16th) were taken on a day that was ~ 40°F. Certainly cold enough to induce cold themogenesis… however, as shown in the video, Eric was wearing long sleeves, pants, etc. The “extended After” reading took place on a 75-85°F day. Eric mentions being hot in the car and driving with the windows down. Even at 70°F, would the windows down (windchill) be enough to induce a low level CT effect? Maybe.Ultimately, it was probably some combination of all factors.
Several questions come to mind:
Q1. — Does this count as your “resting” metabolism, if it’s being boosted by an “external” stimulus, even if the effects can last for over 1/2 a day later?
Q2. — Would this still work in summer? (hotter temperatures)
Q3. — Is this ‘healthy’ to have your metabolism boosted this much?
Q4. — Will it increase hunger?
Q5. — Will it speed aging?
A1. Regardless of semantics, the end result is the same; you end up with a massive, “free” calorie burn, without any further effort or activity, for hours and hours later, perhaps half a day or more. At some point, it is probably constant, 24/7.
A2. The Cool Fat Burner / Cool Gut Buster allow you to engage all the way to ‘Hardcore’ intensity (shivering) even in summer…but you’ll also need A/C and drinking ice water helps. So you’ll have to do your CT sessions indoors during the summer. If you become cold adapted during the summer, do a 1-2 hr Hardcore session, then taper off and lounge in an A/C room (no more than 67-68°F) for a number of hours… one should still have a boosted metabolism for a good part of the day. It is of course easier to get a deeper cold adaptation in the winter months, for obvious reasons…but a significant effect can still be achieved in the hottest summer weather.
A3. There should be no negative consequences to a cold-thermogenesis-induced boosted metabolism. And you’ll burn far more calories, even at rest, even if you don’t use the Cool Fat Burner that day.
A4. No. The only time people sometimes experience increased hunger from cold thermogenesis tends to be during the first few weeks of starting. Once you get used to it, your appetite tends to normalize.
A5. No. Remember, cold thermogenesis can increase adiponectin and irisin. Adiponectin is associated with longevity (1, 2, 3). Irisin can lengthen telomeres. The Cool Fat Burner has also been shown to be able to lower blood glucose levels; low BGL may beassociated with reduced aging.

Compare this to the famed “EPOC” effect fitness people love to blather on and on about! (EPOC is the post-workout calorie burn you get from hard exercise, after the workout ends.
Guess what? It’s rarely more than 100 calories — if that — the whole rest of the day!!!) The RMR boost from the Cool Fat Burner and Cold Adaptation BLOWS EPOC AWAY! *Results may vary.
