I’m not a scientist, I’m a lowly little Personal Trainer and Massage Therapist. I don’t perform studies (other than my N of 1 ones), I don’t write research papers, I don’t have a degree in anything health related.
What I do do is read a lot. Blogs (I’ve got a few of them listed in my blogroll), news articles, and most importantly, science. I try to find and read as many sides of an issue as possible.
And one thing I have, that a lot of people don’t, is an ability to think critically.
There’s a Diet War going on out there. One faction would have you believe that primitive man spent most of his time lolling about the savannah, working on his tan, only getting up off his ass long enough to throw a spear at a passing buffalo, then sitting back down to gorge himself and get back to the serious business of lazing about. Sounds pretty idyllic. Sign me up! Oh yeah, and that buffalo was made out of bacon.
Building on this belief system, they argue that modern humans are therefore primed for a life of blogging and bacon eating. It’s the true path to optimal health! See, our bodies are made to sit and eat fat, so when we eat carbohydrates, everything goes haywire. Insulin resistance, diabetes, obesity, cancer, DEATH.
‘Course, there’s all that pesky scientific data that suggests that increasing physical activity improves metabolic function (don’t believe me? Google ‘exercise and insulin resistance’, or check out my pinterest board on the topic). How can that be, if the body’s natural state is lolling about the savannah? If our bodies are designed to sit, why would moving improve metabolic function?
Do you REALLY believe primitive man spent most of his time on his ass? I don’t, not for a minute. I believe primitive man spent most of his time on the move. I believe the human body’s natural state is one of almost constant motion. When we move, we metabolize carbohydrate just fine. In fact, science holds carbohydrate is the brain and muscles’ preferred fuel (yep, I’m aware of the studies that suggest otherwise. Guess what? So far, they’re outliers). ‘Course, if we’re not moving, carbs can cause problems. But is eliminating carbs the answer? Only if you believe our bodies are designed to sit all day. If you believe that our bodies are designed to move, then eliminating carbs is a band-aid. A band-aid that might allow you to sit on your ass a few more years before disease sets in, but that ultimately doesn’t address the CAUSE of the disease: exercise deficiency. That’s right folks, I’m calling it like I see it: Metabolic Dysfunction is a disease of exercise deficiency, not of carb intolerance.
“But modern lifestyles make adequate exercise nearly impossible!” they claim. Bullshit. I have kids, a job, a household to manage, and a social life, and I am able to include adequate exercise into my daily routine. I also manage to maintain a blog! Yes, you too can blog AND exercise.
“But only young people and endurance athletes can eat carbs safely!” they counter. Bullshit, again. I’m 40. I exercise 30 minutes a day on average.
“But…but…some of us are so damaged by obesity and the Standard American Diet that we simply can’t ever eat carbs again!”. Bullshit, times 3. I was obese for 3 decades. At 35, I had a whole laundry list of metabolic issues: PCOS, high blood pressure, blood sugar regulation control problems, low HDL, and obesity (not to mention depression, panic attacks, migraines, hair loss, cyctic breasts and acne and much, much more). I reversed it ALL while eating carbs.
Ask yourself: which is more likely the natural state of the human body:
a. sitting and eating only one or two macronutrients, to the exclusion of thousands of edible energy sources
b. moving and eating whatever is easiest to find (which, where I live, would be mostly plants, with some rodents, insects and perhaps an occasional bit of larger game thrown in to supplement)
I choose b, and live accordingly (minus the rodents and insects). And you’ve seen my pictures. I suspect I look a lot more like the mythical Grok(ette) than most basement dwelling, bacon eating bloggers.
