an official International Society of
sports nutrition position paper covering
keto diets notes the Ergo lytic effects
of keto diets on both high and low
intensity workouts her go lytic is the
opposite of or go gennaker go genic
means performance boosting whereas agro
lytic means athletic performance
impairing for non athletes ketosis may
also undermine exercise efforts ketosis
was correlated with increased feelings
of perceived effort and fatigue and mood
disturbances during physical activity
suggesting that the ability and desire
to maintain sustained exercise might be
adversely impacted in individuals
adhering to ketogenic diets for weight
loss I already mentioned the shrinkage
of measured muscle size among CrossFit
trainees so a ketogenic diet may not
just blunt the performance of endurance
athletics but strength training as well
half people do you know eight weeks of
all the standard upper and lower body
training protocols benchpress pull-ups
squats deadlifts and no surprise you
boost muscle mass unless you're on a
keto diet in which case there was no
significant change in muscle mass after
all that effort those randomized to the
non ketogenic diet added about three
pounds of muscle whereas the same amount
of weight lifting on the keto diet
tended to subtract muscle and have us
loss of about 3.5 ounces of muscle how
else could you do eight weeks of weights
and not gain a single ounce of muscle
but on a ketogenic died even keto diet
advocates call bodybuilding on a
congenic diet in oxymoron what about
bone loss sadly bone fractures are one
of the side effects that
disproportionately plays children placed
on ketogenic diets along with and growth
stunting and kidney stones
ketogenic diet may cause a steady rate
of bone loss as measured in the spine
presumed to be because ketones are
acidic and so keto dyes can put people
in what's called a chronic acidotic
state some of the case reports of
children on keto diets are truly heart
wrenching one nine-year-old girl team to
get it all osteoporosis bone fractures
kidney stones and then she got
pancreatitis and died pancreatitis can
be triggered by having too much fat in
your blood a single high-fat meal can
cause a Quin coupling the spike in
triglycerides in your bloodstream within
hours of consumption which can put you
at risk for inflammation of the pancreas
she had a rare genetic disorder called
glucose transporter deficiency syndrome
where you're born with a defect in
ferrying blood sugar into your brain
this can result in daily seizures
starting in infancy but a ketogenic diet
can be used as a way to sneak fuel into
their brains so a ketogenic diet can be
a godsend for the one in ninety thousand
families stricken with this disorder as
with anything in medicine it's all about
risks versus benefits as many as thirty
percent of patients with epilepsy don't
respond to anti-seizure drugs and the
alternatives aren't pretty including
things like brain surgery
this can mean implanting deep electrodes
through the skull or even removing a
lobe of your brain this can obviously
lead to serious side-effects but so can
having seizures every day so if the
ketogenic diet helps with seizures the
pros can form outweigh the cons for
those just choosing a diet to lose
weight though the cost-benefit analysis
would really seem to go the other way
thankfully you don't need to mortgage
your long-term health for short-term
weight loss we can get the best of both
worlds by choosing a healthy diet
remember that studies that show that the
weight loss after being told to eat the
low-carb Atkins diet for a year was
almost identical to those told to eat
the low-fat Ornish diet
and the authors concluded this supports
the practice of recommending any diet
that a patient will adhere to in order
to lose weight that seems like terrible
advice there are regimens out there like
the last-chance diet which evidently
consisted of a liquid formula made from
leftover byproducts from a
slaughterhouse that was linked to
approximately 60 deaths well it did
promise to change people's lives an
ensuing failed lawsuit from one widower
laid the precedent for the First
Amendment protection for deadly diet
books it's possible to construct a
healthy low-carb diet or an unhealthy
low-fat diet diet of cotton candy would
be zero fat but the health effects of a
typical low-carb ketogenic diet like
Atkins are vastly different from a
low-fat plant-based diet like Ornish's
not only but they have diametrically
opposed effects on cardiovascular risk
factors in theory and based on fiber and
saturated fat and cholesterol contents
of their representative meal plans when
actually put to the test low carb diets
were found to impair artery function
over time blood flow to the heart muscle
itself is improved on an Ornish style
diet and diminished on a low-carb diet
heart disease tends to progress on
typical weight loss diets actively
worsen on low-carb diets but may be
reversed by an aura style diet keeping
that heart disease is the number one
killer of men and women recommending any
diet that a patient will adhere to in
order to lose weight seems irresponsible
why not tell people to smoke cigarettes
can cause weight loss too as can
tuberculosis and a good meth habit but
the goal of weight loss is not to
lighten the load for your pallbearers
