Iโve been getting a very similar question/story lately. It goes something like this.
Iโve been eating paleo for months, doing high intensity exercise, doing everything right, and I still canโt drop the weight, Iโm still fighting fatigue, and Iโm ready to give up.
That statement in itself could mean a lot of things but for the sake of this post, I want to focus on the high intensity exercise piece.
I LOVE high intensity exercise. I do high intensity workouts in a CrossFit manner. But exercise is actually one of the poorest interventions for you to lose weight. Why? Because most measure exercise in terms of calorie expenditure. I donโt really want to get into the calorie-in, calorie-out falsehood of activity and weight. Instead, Iโm going to focus on the bigger picture.
Get Nervous
If you want to the most out of your fitness routine, you have to make it congruent with your nervous system. Your nervous system has 2 basic sides: Protection and Growth. And if youโve read anything of mine in the past, you know I love Bruce Liptonโs quote, โYou canโt be in growth and protection at the same time.โ
Even though you canโt be in growth and protection at the same time, this doesnโt mean you donโt get the full benefit of either side in the same day, or even in the same minute.
Letโs say youโre out for a walk with your dog and you spot a mountain lion lurking up to the side of you stalking you. This would be a moment you definitely want your nervous system to shift into protection mode. Your brain sends hormones to the adrenals to active cortisol and catecholamines. Cortisol quickly acts to dump sugar from your storage into your blood stream. The catecholamines act on your cardiac output and muscle contraction to prep you for what may happen next.
This protection side of life actually puts you in a catabolic state (tissue break down). The more you demand this side of your nervous system to activate throughout the day, the more your body breaks down. In other words, the more stress you are under (physically, chemically, emotionally, socially, spiritually, etc), the more you keep throwing your body into break down mode.
After a while, you realize you are getting more and more tired, youโre achy, and the weight starts packing on and something has to change.
But if your body is in tissue breakdown mode, why would you actually gain weight? Again, there could be a number of answers. I will simplify this answer to the two biggies of insulin and inflammation.
Fanning the Flames
If you have the typical American busy, toxic, socially isolated lifestyle (even though you eat paleo), your body will favor protection and tissue breakdown to keep you going. The body will do everything in its power to keep you alive the next 30 seconds, even if itโs at the expense of the next 30 years. One of those mechanisms is to dump sugar from stored areas into your blood stream. This is an extremely intelligent action to help you survive.
Your body also has the intelligence to look at the elevated blood sugars and realize thatโs not a good plan long term. As a result, insulin gets released to take up the excess sugar and store it. The first place to store excess sugar is in the liver but thereโs a small limit and once it reaches that limit, your liver puts the ear plugs on and doesnโt listen to insulinโs pleas anymore. Your muscles are the same; only about a dayโs worth of stored energy before they tune out insulin.
The sugar must be stored somewhere so it looks for fats and attaches the sugars to those fat molecules. You know these as triglycerides. Eventually these triglycerides are stored as fat in the non-exclusive club we call the butt, gut, and thighs. Since the excess sugar is stored as fat, this is why fat has been attacked for the past 40 years.
If the constant attacks on your lifestyle were real threats like mountain lions where you actually have to run or fight as hard as possible, you would utilize those energy releases. The problem is that most of your daily stresses are happening while youโre sitting on the very structure youโre trying to reduce, your arse. Though insulin is a growth hormone, when itโs out of control, it ironically is a massively powerful promoter of your sympathetic nervous system (#protection, #catabolic #tissuebreakdown #cantloseweight).
But Wait, Thereโs More
If you have kids, you know sugar is sticky. It especially likes to stick to proteins (think bubble gum in the hair). This process of glucose sticking to proteins is very important in your weight loss journey and part of the reason why high intensity harms. This process of sugar and protein shacking up is called glycation. This process damages the protein to the extent that white blood cells will come around and attack it to try and get rid of it.
Just to remind you, your white blood cells mediate your immune response. Part of that response is to induce a little helper called inflammation. The more damage you induce, the more inflammation is produced to repair you. The problem is that you ignore these signals and continue to push life forward. This keeps you in a perpetual state of running from lions, opposed to supporting metabolism.
When High Intensity Harms
You are at a breaking point and you hear a conversation at work that someone is having fantastic results with high intensity exercise. Youโve noticed the changes in their appearance, their attitude, and you want that. You decide to go for it. You hire a trainer, join a box, or buy a home workout routine that is designed for high intensity. A few months go by and youโre drained, you havenโt lost weight, and contemplating hormone replacement because you think, โit might be my thyroid.โ
Instead, assess if your workout routine is congruent with your nervous system. When there are contradictions, there will be destruction. Here are some contradictions in your high intensity routine you may want to consider.
Time Out
With high intensity training, I think everyone forgets it should also be SHORT duration. If you have a mountain lion breathing down your neck, youโre going all out, max effort. There is no pacing. Itโs go time. Itโs you or the dog. I often see people boasting of high intensity routines that last 30-45 minutes. Thatโs NOT high intensity. Thatโs long drawn out cardio. If you can keep a pace of movement for longer than 8-10 minutes, youโre not going hard enough to call it high intensity.
My workout yesterday was 4 minutes and 58 seconds. Today, it was 7 minutes and 40 seconds. Yes, sometimes I have the 40 minute long session but thatโs the minor exception, not the rule. Scaling your load and repetitions is encouraged. Or dive into weight lifting. Move heavy stuff to the point of failure.
Timing
Your normal daily awake cycle should start off energized and end being tired. This is the normal hormonal cycle of Cortisol. Cortisol should be high in the morning to give you energy to get you out of bed and ready for the day and decline through the day to make sure you can settle down when itโs dark and get to sleep.
I see a lot of hangups with the timing of a high intensity workout. Itโs rush, rush, rush all day with busyness and when you should be settling down to allow your body to recover, you hit the gym instead. The gym is filled with bright lights and pumped up music (a high alert environment).
Because youโve had a busy day, you may have even grabbed a coffee before your workout so you can reach max effort. Youโre doing great at overriding your innate intelligence but eventually that innate intelligence will win out. Your nervous system wants to slow down, yet youโre doing everything possible to speed it back up. This just perpetuates the cycle of escaping lions. With enough time, rest will find you instead of you finding rest. Your body will intentionally slow you down since youโre not consciously doing it for yourself.
Work with your nervous system, not against it. You should naturally have more energy in the morning. Ever wonder why most hunting creatures are nocturnal and humans arenโt? Humans would never survive if we had to hunt in the dark.

If you really want a workout after work, do something more restorative like mobility or yoga that wonโt send your heart rate racing and your adrenals on alert. Getting up in the morning may mean you have to drastically change your evening schedule. My success in a morning routine is by keeping it boring in the evening.
After I get home from the office, we eat dinner together at about 6:30 pm, play with the boys for a bit, get them ready for bed, and then totally veg out. I often lay on the floor doing some mobility and watch some brainless NetFlix with my wife. Iโm a sucker for the shows with a high school setting like Friday Night Lights and One Tree Hill. If only NetFlix had Dawsonโs Creek.
Cheater Cheater Booger Eater
When people do high intensity exercises, this often speeds up the mechanics of the movement. We use speed to cheat. To be clear, thereโs nothing wrong with going fast. But when going fast makes you cheat your full movement, this has the potential to trick your brain into thinking something is wrong. The more you can place your body in full ranges of motion, the more your brain equates that movement with benefit.
If youโre running from that mountain lion (poor choice, youโre not that fast), who cares what your form looks like. Youโre willing to sacrifice the next 30 years to stay alive the next 30 seconds. But when youโre willingly put yourself in repeated high intensity, poor movement scenarios, your bodyโs position will give signals to your brain that itโs potentially injured.
The more you limit that full range of motion, the more your body sends protection signals to your brain. But the more you are able to drop into a full squat or get your chest to the floor on a pushup, your brain recognizes it as beneficial. Smooth is fast. The better your quality of movement, the more relaxed the brain is, which helps you shift into recovery mode after the workout. For you CrossFitters, itโs ok to scale (this might be more of a reminder for me than you).
For the No Intensity Crowd
Iโm sure there a few out there that do nothing and will read this and use it as a case against doing high intensity workouts. Please donโt. In fact I would encourage you to try it. Even if youโre bound to a wheel chair, you can punch the air in front of you. For those brand new to a high intensity, SHORT DURATION, movement routine, follow the timing, time, and booger eater tips to make it successful. I would also encourage you to try it in a 4 minute routine called a TABATA.
Itโs 4 minutes of alternating cycles of 20 seconds of intense work, followed by 10 seconds of rest. Punch a pillow, raise the roof, or stomp your feet. Just do it as fast and with full motion as possible in those 20 seconds of work, preferably in the morning.
Complicating Factors
If youโre already doing these above steps and having road blocks, then often times there are other circumstances that arenโt externally obvious and need further digging and investigation. I can help, you just have to come find me.
