The Real Skinny on Fat – FASTING TIPS with Dr. Joseph Antoun


Thank you so much for being here today
we cannot wait to unpack everything about the fascinating fasting concepts.
Can you tell me your name and a bit about your background? -Yeah and thanks
for hosting me. My name is Joseph Antoun I’m a physician by training and then
upon graduation I felt my passion was more for public health and health policy
and changing the world in the sense of helping people live healthier longer and
after a long track of doing a series of consulting and executive roles and end
up landing on the concept of fasting and healthy aging and reversing biological
aging. -So this this idea of fasting is obviously a very broad idea. Can you
tell me a little bit about what got you interested in it and where it began. -Yeah
so actually this is a very old project of USC, University of Southern
California, and under the leadership of a prominent professor in this field called
Fatulongo, they had a theory some 23 years ago which is, aging is the
catalyst of most diseases and you know we’ve accepted Alzheimer’s comes with
age, we’ve accepted that most cancers and most cardiovascular disease come with
age, but we never blamed aging and once they understood a little bit the
pathways within the cell that tell the cell to grow and therefore to age versus
to hibernate or to or you know or to stay still stands still
and and reverse aging. Once they understood these mechanisms they
identified fasting to be one of the anti-aging intervention to the body so
therefore they got really interested in how to keep people healthier longer by
reversing their biological aging. So it’s basically you chronologically aging but
biologically staying the same or aging at the slower pace and therefore this
pushes the onset of the chronic diseases by many years and
increase your health span. It’s a big word today that we should focus on more
than lifespan because we want to keep people healthier longer rather been
sicker longer. -Interesting. So our health span has actually really gotten shorter
but our life span is longer so we’re unhealthy for longer periods of our life?
-Yes we’ve done a lot for chronic disease management. We did very little on
chronic disease prevention and this is what the focus today of an integral and
functional medicine is and preventive health care is how can we help people
live healthier longer and focus on health span, which is actually what led
me personally to focus on aging and fasting, the impact of fasting and aging,
because I think it’s one of the most powerful intervention you can do
on health span. -Fasting is one of the most powerful interventions that we can use.
And it’s it’s it’s not a simple process but it’s something that doesn’t cost us
any money. We can decide to do it at any point, right. And we have the control
within our own bodies and it has the longest or the best benefit to our
health span. -In part of our ancestors diets before we had..before we invented
how to store food, how to hunt efficiently, etc. They had to go through
days of fasting when there was not food available and so imagine the
northern part of the states in the winter time it was so cold and there was
no food or or preys were not easily available. So everybody actually used to
eat and not to eat. What happens with us lately in the last few hundreds of years,
we eat and eat and eat and we don’t fast anymore. So fasting was part of the diet.
So no eating was part of the eating habits and we lost that and today we
overeat and this this is a mismatch with what our body has been tailored to do or
to cope with. And therefore you start seeing these, you know, lifestyle related
and food-related chronic diseases notably obesity and diabetes. But
also cancer has increased lately, Alzheimer’s and other age-related
chronic diseases. -So talk to us a little bit about fasting. So, for me personally, I
love fasting because I had very severe eczema and that inflammation in my body
was embarrassing and itchy and and would bleed and it was horrible and when I
started to reduce the inflammation just by giving my body a break. So I would
fast for three days, I would fast for five, I would fast for ten, I would go
through different bouts and then I would fast for 24 hours once a week and over all that to me transformed my health and today I
do, you know, I’ll I’ll not eat for about 16 hours and I know that there’s so much
new research so can you talk to us about the different types of fasts and what
and how and why? -When you want to mention the word fasting biologically your body
doesn’t fast if you skip food for eight hours or seven hours or 10 or 12 because
you’re still absorbing and processing the growth and the postprandial
secretions from the last meal that you ate. So sometimes actually you go to work
you’re so busy during the day and you know you’d only eat you know in the six
or seven pm time. So you spend you restricted your food that day to say the
the the last meal you get that night but it doesn’t mean you fasted. Yes, you
stayed without food ingestion for several hours but your body is still
biologically processing what you had for breakfast or dinner last night. So
biologically we don’t like to call it fasting but I understand why people
would call it practically as a type of fasting. We call it mostly time
restricted feeding. -So from the time that we eat a meal, how many hours do we need
to wait until our body actually starts to fast? -So biologically we believe it’s
24 to 30 hours, actually, until it’s closer to failure so there’s a good
eight hours for digestion and the direct digestion and and effects of that. But
then also there’s the signals of the body of, ‘Hey you know there’s some macro
macro nutrients that came to the body, the proteins, the carbohydrates, the fats
etc.’ And the body process is the consequence of that and the cells
nourishes, you know, itself and you know insulin is gonna increase and so
like growth factor and all the postprandial if you want biological food
processing. -So you use the word postcranial that’s really the time after
we’re digesting or while we’re still finishing digesting? -Yeah that takes up
to eight hours but then after that there’s a signal in the body that
there’s food and therefore the body is still at the cellular level you know
getting getting the ripple effect of food and doesn’t really go into fasting
until you go up to thirty hours with no food.
-So you’re in what’s considered a post perennial state? So you eat your food and
then your post-perennial up to 30 hours of not eating and then once you hit that 30
hour then you go into fasting? -Then biologically your body is fasting.
-And once your body goes into biological fasting, what’s going on? Why is this the
biggest buzzword? -Yeah what goes on depends on what you do after. If we eat
again then we call it intermittent fasting meaning you fasted say for a day,
the 24 hours, then you eat again and then in two days afterwards say you fast
again and it’s a very popular way of doing intermittent fasting what we call the five-two, if
you heard about it meaning five days during a week you normal and a couple of
days you eat you know below 500 or below 600 calories to try to mimic fasting. So
what happens after the 24 or 30 hours depends on what you do. If you eat again
then your body gets food again and basically you skipped food intake for
for a good long period. Which is very good for, you know, weight loss and for
basically allowing the body to spend what it ate or what it’s stored and then
the body spend it. So this is why intermittent fasting has been, you know,
has shown to do very well with metabolic related weight related metabolic
issues because it’s helping you to decrease calorie intake say once or twice
or three times a week depending on how you do it. -So even in those first thirty
hours from what you’re saying there are a lot of beneficial biological effects?
-Because in parallel you’re spending calories. So what your body has just
ingested if you want x calories has enough time to respond it rather than to
store it and then eat again in the next six hour and then you can eat again in the next six hours etc and this is one of the actually contradictions today that we
have with say 15-20 years ago when the big theory was eat multiple times a day
and what we know this is that, yes if you want to decrease the portions and eat
multiple times the total amount of calorie probably is decrease
proportion but actually your body is in constant mode of growth because it’s
receiving food every say four or six hours. And that growth you know we biologically grow towards our end. We don’t grow
laterally or the third dimension, we grow towards our end. And the more you push
the body biologically to grow, it’s actually speeding aging and it speeds
all the age-related diseases. -It’s it’s an unbelievable achievement to think of
all the years of research the level of researchers and the work that they’ve
done to be able to have something that someone can take and benefit from is a
huge gift and and I’m so happy to have had the opportunity to interview you and
learn from you Thank you Dr. Antoun.
