Calories in versus calories out is one of the fundamental ‘laws’ of nutrition. Though it upholds both the law of thermodynamics and the conservation of mass, the calories in versus calories out theory doesn’t hold up when applied to the human body. If anything, it is a guiding statement based on a law.
When looking at a true closed system (humans don’t count), any possible conversions of energy can be predicted down to a single joule, with nearly 100% accuracy. This is because our equations for energy transfers in closed systems are very good.
When looking at an open system, like the human body, we also have a set of equations we can rely on. Unfortunately, they’re not quite as good as their closed-system counterparts. As an example, lets look at the most commonly used equation to determine caloric expenditure and your basal metabolic rate.
Still, it’s not an absolute rule. There are many other factors that influence the metabolic rate that are not included in the Harris-Benedict equation. These include:
• Adipokine status, including leptin, adiponectin, and resistin.
• Thyroid hormone status
• Steroid hormone status, including estrogens and androgens, as well as DHEA.
• Mitochondrial efficiency and ‘uncoupling’, also known as thermogenesis.
The formula doesn’t include these factors because it is impractical to expect people filling out a BMR equation to know their mitochondrial efficiency.
Moreover, the activity levels are vague.
What feels ‘intense’ to one person could be ‘moderate’ to another. A misinterpretation of activity levels for someone with a 2000kcal intake could result in a difference of up to 700kcal.
Calories in, as a concept, is fundamentally hard to predict. Differences in food absorption, whether due to genetics, nutrient co-ingestion or even the shape of the chyme in your stomach are hard to account for. The differences in nutrient partitioning after absorption, or whether the nutrients go to muscle, glycogen or fat are even harder to predict.
Blah Blah Blah Blah Blah!!!!
These are ALLLLL of the things that I look at...but they are not the things you need to look at...
Listen, the science is clear...but you are not, not working out because the science is not clear or because there are not enough studies the prove that you should...
You know you need to workout, You know you should be eating better...
What you might not know is that there are other opportunities to eat better and train better...that do not involve endless hours of cardio or at the gym on machines you know really know how to use...or worse following an eating program with foods you hate....
I know this email was long...and you hate the 2 or 3 minutes that it might have taken you to read up until now, I mean we didn't even warm up...
But...I wanted to DRIVE the point home...so that maybe you can think about things differently for once
AGE DOES NOT SLOW YOUR METABOLISM... YOU DO BY NOT TAKING CARE OF IT
BEING A MAN OR A WOMAN WON'T AFFECT YOUR METABOLISM... FOR THE MOST PART
YOU CAN START DOING THINGS A LITTLE MORE EFFICIENTLY WHEN YOU HAVE A BETTER UNDERSTANDING OF HOW TO DO IT AND FINALLY GETTING THE RESULTS YOU WANT
and last but not least....I AM HERE TO HELP YOU WITH THAT
Let's Keep It Super Simple
Super Tuesday at Bootcamp starts at 5pm tonight
See you at 5pm, 6pm or 7pm
