Meet Eric (pictured above as he stares off into some mysterious icy wilderness).

I’ll keep this simple for you: Eric is mildly obsessed with the use of cold exposure to burn massive amounts of calories. He invented a vest that I use every week, called a CoolFatBurner. You put the vest over your shoulders, where your body carries the majority of your rapid calorie burning brown adipose tissue, and then you just sit there.

Oh yeah, one other thing: the vest is filled with cold packs.

So anyways, you may be scratching your head, you may think all this is woo-woo, you may already know about “cold thermogenesis” but you’re not quite sure how practically to do it, or you may simply want an easy way to nudge any extra holiday calories off your waistline and instead use them to generate pure, clean body heat.

Either way, keep reading, because Eric is today’s guest author, and he’s going to give you a glimpse inside the nefarious, shivering mind of the ultimate fat burning weapon inventor – himself. Enjoy.

Howdy and Happy Holidays.

If you’ve been reading Ben’s blog or listening to his podcast for the past year, then you probably already know of the fat-burning benefits of cold thermogenesis, cold showers, keeping your house cool and wearing special gear that keeps you cold.  Along with interviewing guys like iceman Wim Hof and neurosurgeon Jack Kruse, Ben was the first person to reveal the results of my groundbreaking indirect calorimetry experiment, which shows that high intensity cold stress can boost your metabolism by 301% (gotta love burning an extra 600 calories while I play video games).
Since then, I’ve shown that wearing my Cool Fat Burner vest can boost adiponectin by 60% in two hours, raise resting metabolic rate, and activate brown fat – and keep it active for hours after removing the cooling vest. We later duplicated this experiment last August, just to further show the cold thermogenesis can maintain maximal brown adipose levels even through a hot summer season. Using the weapon of cold, we also showed that you can spot reduce stomach fat via cold-induced fat cell apoptosis.

That’s fat cell death. Goodbye muffin tops.

But we now know that the Cool Fat Burner can do a lot more than speed up fat burning. It can also directly encourage muscle growth.  This is arguably just as important as the fat burning benefit.  Why?

As of the time you are reading this, over 2/3 of Americans are overweight, with the modernized world not far behind.

But when many people try to lose weight, they end up losing muscle tissue along with that fat, sometimes losing a lot of valuable muscle that can be very, very hard to get back!  This is obviously not good.  Aside from the fact that you’ll look less healthy, be weaker and have decreased performance at most physical tasks, you may also be at higher risk for the various metabolic and “lifestyle disorders” you tried to avoid by losing weight in the first place.

And now, since you lost muscle, your workout capacity and resting metabolic rate have dropped, which means that what used to be a maintenance level of food that was burned by your own muscle is now a calorie surplus!

So your purpose in become the ultimate fat-burning machine is clear: you want to be able to burn fat, while preserving (or even building new) muscle.

How To Burn Fat And Build Muscle At The Same Time

Cold thermogenesis can be your secret weapon in this battle that so many others struggling at the gym don’t (yet) realize.

To help maintain muscle while you burn fat, cold thermogenesis can help you:

So cold thermogenesis can not only boost metabolism, burn a massive number of calories, and help keep the fat off, but it can also help preserve and even promote muscle gains. Click on the links for yourself. The research has spoken, and it just makes sense when you think about – in the same way that exercise can be uncomfortable and eating healthy or skipping a few holiday bottles of booze can be uncomfortable, cold exposure can be uncomfortable – but the benefits of even mild cold stress are profound. Discomfort pays off.

So what is the best protocol to optimize cold thermogenesis and make all this happen?

——————————————–

How To Use Cold Thermogenesis

I’ve integrated some of the most effective diet plans, workout paradigms, and cold thermogenesis breakthroughs into what I call the “Body Recomp” plan.  This plan is highly individualized and customizable, since it’s really just a set of principles that you pick and choose as you please, combining diet, exercise and cold stress in the absolute best ways to meet the goals of burning fat, building muscle, and improving health, with the speed at which you go dependent on how far you’re willing to take the diet and the cold.

Is your goal to eat 18 scoops of ice cream (dairy-free vegan coconut ice cream, of course) and partition those calories away from fat and instead shove them into muscle, all while still walking around with exemplary health markers and clinically low insulin levels?  Well, here you go:

Eventually, I’ll have the Body Recomp plan up on the new Cool Fat Burner site with free access.  Until then, I’m going to give you a few general concepts, principles, and practices you can get started with.

To begin, you must understand two simple concepts: mTOR and AMPK – one builds up and one breaks down, respectively. The table below fills you in.

Cool Fat Burner

 

The key in building muscle and burning fat at the same time is to unlock the benefits of both these processes, while avoiding the negatives of both – to build your muscles, without increasing fat storage or abnormal, cancerous cells and to burn fat and clean up bad cells without tearing down muscle.

Cold thermogenesis spans the gap.  It has been shown to accelerate fat loss and kick in AMPK, and yet the effects of both irisin and adiponectin can help preserve muscle tissue and activate mTOR.

And that, in a very basic scientific nutshell, is how you build muscle and burn fat at the same time.

————————————–

The Levels of Cold Thermogenesis

Back when the Cool Fat Burner was first created, I defined 3 distinct levels or intensities of cold stress, based on the level of cold stimulus required, the systems they activate, and the results they give you.

Level 1: Beginner / Casual Intensity:

This feels like being lightly cooled off, and would be like hanging out in a 65°F room with minimal clothing. It activates the autonomic nervous system, and causes a small increase in calorie burning (probably around 10%).  This is a low level of cold thermogenesis, and could be done for hours a day, with minimal effort.  You may even experience enhanced glucose uptake at this level.

For example, I received an email from a Cool Fat Burner user who wasn’t ready for the insulin sensitizing effects of cold thermogenesis. He said he wore the cooling vest over a T-shirt, and when he approached the 30 minute mark, he nearly passed out! When I questioned further, it turned out his mother was diabetic, and that he was 100lbs overweight and had a fatty liver.

Simply put, the customer had poor insulin sensitivity, and was pre-diabetic and cold thermogenesis caused a massive burning up of blood glucose, pulling it into brown fat and muscle tissue!

Even though I don’t encourage cooling yourself into hypoglycemic shock, this of course proves the power of cold exposure, and demonstrates why brown fat is being researched to help treat or even prevent (T2) diabetes.  It also demonstrates that you need to be careful when engaging in cold thermogenesis, because it actually works!

Level 2: Moderate Intensity

This is a deeper chill, and starts to activate brown fat and skeletal muscle uncoupling.  This will definitely increase glucose uptake and start to allow for nutrient partitioning.  The calorie burn numbers here can depend on how much muscle and brown fat you have (you’ll burn more calories when you maintain muscle while losing fat).

Also note – cold thermogenesis can maintain maximal brown adipose tissue levels even through summer, which I found when wearing a cooling vest around 1.5 hrs a day, and verified with PET scans.  So while hot weather will decrease brown fat in everyone else, you can use cold thermogenesis to maintain maximal BAT levels and fat burning even through the summer.

Level 2: Hardcore Intensity

This intensity ventures into the realm of shivering.  But before you go running for the hills, understand that there is a spectrum here – this can be a subtle, barely perceptible pre-shiver that only works in small muscle groups, and progress up to large-scale shivering shaking your entire body.

Even in the indirect calorimetry experiment, doing slight to moderate shivering, interval shivering (so-called “shiver surfing”) I demonstrated a boosted metabolism of over 300%.  This level also produces the highest levels of adiponectin and irisin.

So shivering will burn a massive amount of calories, can help preserve or even build muscle, can radically increase insulin sensitivity, causes the fastest increase in your regular brown fat stores, and cause “browning” of your subcutaneous white fat into “bright” or “beige” fat, as well as a whole host of health and life-extending benefits (some may mistakenly think that hardcore intensity would be an unpleasant experience, but they’d be wrong).

——————————————

Two Sample Days Of Cold Thermogenesis

So, using these principles and applying those various intensities of cold thermogenesis, here are two sample days from the Body Recomp plan. Example one is for clean-bulking muscle (e.g. you want to build muscle and you really don’t have much fat to lose), and example two is for fat burning without losing muscle.

Example 1 – Anabolic Day (clean-bulk muscle building):

Goals:  turn on mTOR, build muscle without gaining fat.  Enjoy cheat foods.  Increase metabolism.  Have a ‘break’ from dieting.  Enjoy satiety, experience a full stomach.  Overall ‘building up’ of the body. Yep – you guessed it – perfect for the holidays.

Meal 1: Breakfast

Breakfast-5 eggs, 5 strips bacon, assorted nuts (almonds, walnuts, pecans, cashews, Brazil nuts, etc)

-~50gm protein, moderate fats, very low carb  (usually take fish oil and chia seeds and fat-soluble vitamins like Vit D with this meal)

Note: Brazil nuts have a lot of selenium, which can build to toxic levels.  Eat in moderation.

If your workout suffers from having no carbs and you’ve ruled out it’s not just psychological, then throw in some slow-digesting carbs.  Oatmeal would be an excellent choice.

Workout 1: Early afternoon, muscle-building resistance training.

New PictureNOTE:  “resistance training” is a bit ambiguous.  We know that progressive overload is needed to preserve / build muscle.  Yet it’s recently been implied that the differences in rep ranges – the classical 1-5 reps for strength, vs the 7-12 reps for hypertrophy – may not be as clear cut as we once thought.

It appears one should work a muscle at least 2-3 times a week, anywhere from the “power rep range” (typically 1-5 reps) to the “hypertrophy rep range,” (usually 8-12 reps) and still get the same muscle size growth or preservation.  So specific rep ranges may not be too important in terms of muscle size and preservation, and individual goals, can factor in here.

Note:  On a more metabolically intensive variant of the Body Recomp plan, you can cycle in extremely high rep work, complexes, anaerobic work, metabolic work, HIIT (high intensity interval training), and LISS (low intensity steady state cardio).  You can also frequently cycle the type of exercise, as well as add ‘exotic’ methods, such as resistance bands, paused reps and timing schemes, partial movements, conjugate principles, and so on, to prevent plateaus and boredom. To preserve muscle simply means you need to spend adequate time on strength-end of the strength/endurance spectrum.

Meal 2: Post-Workout Meal (carb refeed)

post workout-Chicken thighs, lentils, sour kraut & kimchee, sweet potatoes, greek yogurt, an apple (usually w/ caramel dip), and dark chocolate.

-Lots of protein adequate carbs, as well as fiber and pro/pre-biotic elements.  (if you take probiotic pills, this would be a good time to pop ‘em)

-At least 50-60 gm protein in this meal.

-Alternate post-workout meal:  Junk food / cheat meal version:  use your imagination. Just make sure you get enough protein and make every attempt to keep things Ben approved. A giant gluten-free pizza with a pastured egg and some feta cheese on top? OK. A basket of greasy, inflammatory chicken wings? Probably not.

Note: While it may only take 20 gm protein to increase muscle protein synthesis, it’s still probably a good idea to get more protein per meal, especially if you’re older, andI never get less than 40gm protein in any given meal.  I like to get .8 to 1 gm per pound bodyweight every day, divided into 3-5 meals.  I weigh between 190lbs to 200lbs, depending on current goals, so I never get less than 150gm protein a day.

Note #2: the carb refeed can boost leptin and thyroid, can help reduce muscle protein breakdown, replenish muscle glycogen, and provide a psychological break from the diet.

cold thermogenesisCold thermogenesis / Cool Fat Burner session

After this post-workout meal, I’ll go for 1.5-2hrs wearing one or both cooling vests (Cool Gut Buster along with the Cool Fat Burner)

I may not shiver during this session, because I don’t want to burn off too many calories, nor activate AMPK – I want those post-workout meal calories to go into muscle building.

The goal here is for increased nutrient partitioning and pushing the nutrients into the muscles. I’m not really trying to burn too many calories, unless I went overboard with the junk food and fear carb spillover.  Moderate intensity cold thermogenesis is enough.

Meal 3: Night Meal

night meal-Huge 2.57lb taco salad (yes, the scale was tared for the weight of the plate and fork)

-Probably at least 80 gm protein.  High protein, moderate fat, lowish carbs (no wrap or chips here).

So by the end of the day, I probably had nearly 200 gm of protein and I had a decent amount of carbs (almost all in the post workout meal).  The ‘cleaner’ version of the PWO meal had a lot of fiber, prebiotics, and phytonutrients.  The junk food version (not pictured) would be lacking in all that, unless I took fiber supplements and vitamins with it.  Lifting was done somewhere in the 1-5 or 8-12 rep range per set, trying to get a minimum of 30 reps per muscle group for the whole workout.  Cold thermogenesis was used to help catch any extra calories and hopefully push them into muscle and BAT.

So the end results would be increased muscle growth, boosted leptin and thyroid, a psychological break with the cheat meal, a full belly, and muscles that would feel pumped and full with little to no added fat, all followed by a deep, restful sleep.

Example 2 – Fat Burning Day (burning fat without losing muscle):

Goals:  Fasting or “PSMF” (“protein sparing modified fast” to maintain muscle synthesis, since muscle synthesis can continue for up to 48 hrs after a hard workout).  Huge calorie burning and fat loss.  Activation of cellular cleanup and the enhancement of health and longevity via AMPK pathways.

Note:  much of day will be spent in either an air conditioned environment (if it’s hot outside) or with heat turned down or off (winter).  Ideally wear minimal clothes.  Keep fingers, toes, ears, and nose warm.

Meal 1: Breakfast

breakfast 2Optional:  fat-based coffee

Also take fish oil and chia seeds, as well as any fat-soluble vitamins here, such as Vitamin D or Vitamin K.

Note: The coffee will help to shut down appetite stimulation, and the fats will lessen gluconeogenesis of the PSMF protein-only breakfast (e.g. the ability of the proteins to turn into sugars).

protein slurry-Protein slurry.  60-80 grams of casein (and egg?) protein powder, with powdered peanut butter (or – since I know Ben is reading this – raw almond butter) and almond milk or coconut milk.  Bacon on top.

Note: Consider avoiding whey (and maybe egg) protein if you’re trying to maximize AMPK.  Whey contains a lot of the amino acid leucine.  Leucine activates mTOR.  This is good on anabolic days, not so much on fat burning AMPK days.

Remember, AMPK is involved in cellular cleanup, the destruction of harmful junk cells, and longevity. We want to maximize AMPK on this fat burning day.  So at least for the morning hours, consider keeping insulin low, mTOR turned off, and AMPK revved up as high as possible.  That means not eating whey, and possibly not even eating eggs, as they too can be insulinogenic, turn on mTOR, and turn off AMPK.

Meal 2: Late Morning / Early Afternoon Meal

pre-cool fat burner session-Pre- Cool Fat Burner session.  Huge protein smoothie.  (at least 40-50gm protein for me at ~ 195lbs)  Lots of ice, to chill the insides.

-Long, hardcore cold thermogenesis session.  I’ll go at least 1.5 to 2hrs.  At least 1 hour will be spent somewhere around shivering.  (NOTE:  it is not advised to wear a cooling vest longer than 30 minutes without medical consent)

Even after removing the cooling vests, I’ll lounge in the same cold room for at least an hour or so. So this single session alone could run upwards of 4 hours. But I’m still being productive (and yes, also playing video games) during those 4 hours.

Meal 3: Late Afternoon Meal

turkey burgersTurkey burgers on Portobello mushroom ‘buns.’  (salted stems used as ‘fries’)

High protein, low fat, no carb.

Evening cold thermogenesis.

evening cold thermogenesisTake a chill-walk, wearing the CFB (CoolFatBurner vest) if feasible.  The extra walking will serve as low intensity steady state cardio (LISS), and adding cold thermogenesis to the mix adds even more calories burned.  Go for at least an hour.

Note:  Dress lightly if possible and walk slow and casually, so as to not generate too much heat via exercise.

Meal 4: Night Meal

night meal 2-~60 gm of protein.  Cod, broccoli, and zucchini.  High protein, moderate fat (butter and almond flour on zucchini), low carb.

-At least 200 gm of protein for the day, very low fat and carb.  PSMF.  (eat at least 1gm protein per pound bodyweight on fat burning days, to help preserve muscle)

So with an already boosted metabolism, I’m already in a huge caloric deficit from the PSMF.  Add to that many hundreds of calories burned from the CFB and I should easily hit 1/2lb of fat loss this day.

What’s more, by keeping insulin low especially through morning, by depleting glycogen all day, ad by being in constant fat burning mode, I’m maximizing insulin sensitivity, improving health markers, activating AMPK, and doing some serious house-cleaning on the body’s cells.

————————————-

Summary

So that’s it!

Yeah, I know you probably have questions, so leave them in the comments section below. I’ll answer.

These two sample days were obviously opposite in nature and outcome.  Anabolic growth vs. metabolic cleanup.  Building muscle and repairing tissues vs. burning fat and cleaning up cellular junk.

So choose your goal. Then, as a famous shoe company once quipped, just do it. And yes, either strategy is 100% Ben Greenfield approved and endorsed. Have fun.

Cold thermogenesis and the Cool Fat Burner can help with both.

    1. If you check out the "Gut Buster – Spot Reduction" video, you'll see that I was able to get skin temp down in the apoptosis range of coldness… above freezing, but below 41'F. Of course, other things really factor in — room temp and so on.
      http://coolfatburner.com/can-cool-gut-buster-spot…

      Also note, the Gut Buster isn't meant to be worn against bare skin; it's very easy to get cryoburn this way.

      1. I use the GB tight against my skin. I suck it up tight. I would have gotten burned in the past but not anymore.

        The cloth of the GB seems enough of a buffer.

        Still not sure if it is getting cold enough on the skin. Any other tips?

        1. It will depend on you (how much heat you generate, in part dependent on how much fat is there, since that fat tends to be "stubborn fat," which has less blood/heat supply) as well as room temp.

          As shown in the Gut Buster / spot reduction video & experiment, I was often able to get my stomach skin temp down to the high 30's'F, cold enough for apoptosis. But I was in a cold room during that experiment (probably in the high 50's — it was winter, had heat off and window fan blowing in cold air, but computer and TV generate heat)

  1. Great post, thank you! I usually do an icebath once a week. I go 3-5 times from the sauna to the icecold water, take few swimstrokes and go back up. Then during my swimming pool training sessions I do a cold bath of approx 15-30 sec before and after the pool session (water temp around 6-10 Celsius). When I do these 2-4 times a week, do you think it is enough to keep the body in fatburn state? Thank you and Merry Christmas!

    1. The shorter burst cold thermogenesis seems more to work on the catecholamine response, may help boost the immune system somewhat, and so on. So it may give a bit of a metabolic bump, but probably not enough to induce significant changes on it's own.

      You gotta figure that sheer time is a factor. Meaning you typically gotta do it for more than a few minutes to see any significant change. Also keep in mind, if you're doing it around workout times, your body is gonna generate a lot of heat from the training. Of course, cool water will pull that heat out and give an enhanced calorie burn, especially if it's cold and/or long enough.

      When I do my chill walks (like in the pic at the top) I try and walk as casually as possible, so as to not generate any heat.

  2. Living in the great white north, why is the vest better than simply going out in the cold? I live in the Wyoming Red Desert, where we see snow from September til April.

    1. It may not be, depending on your situation.

      For example, if it's below 50'F at your place much of the year, and you leave the heat off and spend a lot of time wearing just shorts, you could build up some good cold adaptation.

      Keep in mind that some benefits of CT (from irisin and adiponectin) probably require a certain amount of shivering for those hormones to be boosted.

      Of course, if you live w/ other people who want a heated house… that could be problematic. ;D

    1. Well keep in mind, cold thermogenesis can speed up acquiring of ketosis. In the vid I mentioned one day, during a modest reefed, I ate a huge hoagie and a bowl of cereal, yet still (barely) stayed in ketosis. The point here is that CT can really deplete glycogen.

      So going LC/HF and doing CT will really speed that up. So you'd want to be aware of that. (for example, it could seriously effect HIIT interval anaerobic endurance type workouts)

  3. Eric, any clue on how this affects testosterone/libido and/or any adrenal issues this might cause? Or would it be good for the adrenals?

    1. Hey Daniel,

      Some sources out there claim that CT can cause cortisol to rise… but then so can exercise, fasting, low carb, and any other number of activities that burn fat. Also many people report back deeper, more restful sleep from using the Cool Fat Burner; this would obviously help lower cortisol. Also the ability to eat carbs frequently could help.

      I've also talked to a few experts about the Cool Fat Burner vest boosting 'NO2' which would enhance libido, but we've done no testing on that yet. :D

      Actually as part of the Body Recomp plan experiment, my testosterone doubled, from the 'Before' to the 'After' of the first leg of the experiment in March. Thing is, testosterone is so variable; sleep, diet, exercise, all these things can cause spikes or dips on a particular day. (I forgot to include that in the vid, will be in the write-up though)

      Also seem to recall Ferris claiming that CT could boost leutinizing hormone, which *might* increase test production (similar to how SERMs cause an increase in LH, which causes the testes to produce more Test), but that was in animal models IIRC.

      I did some research and talked w/ a few renowned doctors in the TRT field… and one thing that amazed me, is how much more we have to learn. (meaning even the experts are still learning about all this stuff… and many experts disagree on certain things)

      It seems hormones are so damn complex and interconnected, that one shouldn't rely on any one thing to 'fix' them, but should try and use everything synergistically, holistically, to get the best results. Even things like exercise that boost Test or gH, those levels aren't staying boosted long. Probably the only 'quick and easy' way to radically change hormones is with medication, which will no doubt come w/ it's own issues.

  4. How long does it take to see the results from spot reducing with the CGB? Also how many times a week do you do it to maximize the results?

    1. In the literature, it actually takes a few months to see visual changes from cold-induced spot reduction, as it takes time for the dead fat cells to be reabsorbed.

      Of course there is probably a "sweat spot" where you'll really notice this more; probably right on the verge of having abs, or just below. Probably around 14-16% for men. Too obese, and it's drops in the bucket. Too lean, and there isn't really enough there to spot reduce noticeably.

      Though even when I was fairly lean (8-9% calipers, 12% DEXA) I was still able to notice a change, meaning the total disappearance, of my love handles in the back. They were VERY stubborn, and refused to go any other way. The Gut Buster, the way I wear it, it really 'lodged' the Hybrid packs against the love handles, so they were really getting frozen LOL. Even got cryoburn there a few times.

  5. Hey Eric,

    Thanks for the great article! I live in a warm climate and have been experimenting with my own ice packs. I can barely get goosebumps even though my skin goes numb from the cold. Would your vest and ice packs give me a better result (shivering) with my house temp around 70?

    Dana

    1. If your house is around 70'F, you could definitely hit shivering with the CFB/CGB combo.

      Are you gulping down ice water throughout your session? Not just drinking it, but gulping it down, so as to get the cold down in your, not letting it warm up on the way down?

      I'll often cycle 2-3 huge glasses in my freezer, often drinking ~ 1 gallon of water during my sessions.

  6. Hi Eric & Ben,
    I've been a CFB vest & Gut-buster user for the past year and love it! It been part of what has helped me lose weight (45lbs), still have 30lbs to go. I've stopped because of time in the past 3 months and just this week I've changed the strategy on using it, want to know your thoughts.

    I commute 45 minutes each way, I've been using it in my car, fully blasted A/C and two big bottles of ice water. Would it be OK if I use it in the mornings on my way to work and then afternoons on my way back? So twice daily for 45 mins each.

    I don't have time to use it before work and when I get home I can't sleep if I use it at night, I would be hyper afterwards.

    Thanks again!
    Mike

    1. DIET: isocaloric (adjusted for workout and if need be, CFB use), with complex carbs PWO. The meal shown in the video as the carb re-feed (chicken, lentils, sweat potatoes, etc), that would also be the sort of thing I'd eat PWO on the Adaptive days. On the Anabolic days, I'd actually usually eat a bunch of junk food w/ protein powder and vitamins LOL. (I mention that in the article, but don't show pics)

      EXERCISE: classical hypertrophy work, on the opposite muscle group as the previous/next day. So if I did "Pushes" the day before (squats, chest, shoulders, etc) then I would do "Pulls" this day. (posterior chain work) in the proverbial 8-12/15 rep range.

      That allows me to hit each major muscle group 2X per week, once Power/Strength, once Strength/Hypertrophy, as well as work in 1 workout of sprints, and/or 1 LISS workout.

      The Metabolic variant allows for a LOT of that kind of stuff.

      CFB use: tends to be Moderate-to-Hardcore intensity sessions, but only 1-3hrs total. (not the 6-8+hr marathons on Fat Burning days)

      But this is the type of stuff that should be kept for the private info on the CFB site to CFB owners. ;D

    1. Probably best you email them directly – [email protected]

  7. Ben,

    I know this article is 1-1/2 years old, does the science still work? Do you still wear the vest and how does it compare to simply taking a 2-5 minute cold shower? Who is this sort of thing good for? I run ultra marathon distances and dont necessarily have a ton of extra fat to lose.

  8. Very interesting. Is this recommended for fat loss for a 35yo male, 20% body fat, recouperating from adrenal fatigue (low cortisol, low DHEA) or should they wait until they have normalised their hormones?
