How Many Calories Do You Burn with Flex 151?

by Shaun Angel, Owner, CPT

Great question!  The answer is ‘it depends’…on hormones, diet, and intensity of effort while working out.  The short answer:  probably somewhere around 200-250 calories for a normal, healthy and lean person.  

The exact answer is not really known because during an exercise session, there are a lot of factors that come into play since our body is so complex.  We really don’t burn that many incremental calories when you think of how many calories we really eat daily.  Most people workout, get hungry, and then do compensatory eating, thinking they can reward themselves with a sugar filled dessert/latte/etc since they worked out.  It is not exercise’s main duty to burn calories; that is what proper nutrition really does (burn calories through optimized hormones).  The fitness industry just keeps pumping out misleading information like someone running on a treadmill actually burned 300 calories in an hour.  The treadmill and wrist calorie counters just use a math equation to apply to your basal metabolic rate.  The 300 calories you see on the charts from an hour of running includes the 70 or so calories that would have normally kept your systems running and alive anyway.  SO, an hour of running did not burn 300 calories…more in line with about 225 max; however if someone grabbed a sweet electrolyte drink, latte, large meal, etc. and spiked a bunch of blood sugar after that hard workout, their metabolism quit burning as many calories because the sugar from the food was easier for the body to use than converting body fat or growing new and/or strong muscle.  The key is optimizing hormones…the chemical messengers than govern our body and human health.  It is after the session that determines largely what our hormones do, and subsequently, how many incremental calories above normal metabolism can be burned.

The standard workout mantra of ‘burn calories’ while exercising is more than misleading.  We have a basal metabolic rate that keeps our body alive while not exerting our muscles.  This is what doctors many times call ‘resting metabolic rate’.  With Flex 151, you workout hard and we don’t worry so much about weight/time on the clock.  If we tap out a large amount of muscle glycogen (storage form of blood sugar) in our brief intense workout by working to failure, the science shows us that the body will burn more fat (as long as sugar is held low in our diet!) by converting fat back to sugar which then fuels our muscles and liver during the rest periods.  Every week we raise the bar and trick the body to do this again…so our muscles get stronger and hold (and burn) more glycogen during our anaerobic workout.  We get more resilient long term to gaining weight largely because of the better blood sugar regulation and insulin sensitivity that strength training offers.  This corresponds to calories in a major way because you will be more insulin sensitive and be better at clearing glucose from your blood after meals.  (the opposite of what occurs in Type 2 diabetes).

With every pound of new muscle formed comes about 50-100 calories of resting metabolism per day.
Gaining 5 pounds of muscle yields 250-500 incremental calories burned daily to keep your new muscle alive. (Now we are talking….that sounds significant to me!)  In the muscle is where we produce ATP (energy) and burn sugar (glucose).  So, people who do not use their body in a demanding way will lose, after the age of 35 yrs old, 1% to 1 pound of muscle per year, on average.  This is known as sarcopenia, or age related loss of muscle.

The fourth yama, brahmacharya, is popularly known for two meanings - chastity and moderation. Overall, Brahmacharya asks us to think about where we're putting our energy (sexual or otherwise) and if we're directing it towards useless places, to figure out how to redirect it. "Each and every act and thought is an outflow of energy," says Reverend Jaganath of the Yoga Life Society. "Some thoughts and actions offer beneficial dividends, while others simply drain our resources." Practicing brahmacharya encourages us to let go of the things that do not serve us and enjoy everything in moderation.
