Triathlon Taren lost 10 pounds in 5 days by using the Fast Mimicking diet by Dr. Valter Longo which looks to achieve many of the weight loss benefits of …
– 10 pounds, 10 pounds is
how much weight I have lost
in five days doing the
fast mimicking diet.
Now before you all start turning
into a bunch of scientists
and ripping me apart in the comments below
about the dangers of fasting,
the benefits of fasting,
how to fast, what the heck
a fast mimicking diet is
we're gonna talk about it, okay?
(upbeat techno music)
Alright, so fasting,
just like keto dieting,
has been all over the interwebs.
I'm also gonna preface all of this
by saying this isn't an
endorsement for fasting,
this isn't how I
recommend you should fast.
I'm not even recommending you should fast
I'm just talking about
what I've tested out
over the last five days
and if you wanna test it out yourself
here are some things
that I've gone through
but make sure you consult
your own physician,
make your own decisions.
We're all adults here,
except for the kids that
watch this, thanks kids.
Okay, so the current science
of fasting shows a few benefits
that can help us all out.
Number one, weight loss.
Number two, it stimulates autophagy.
Autophagy is the breakdown and destruction
of dysfunctional cells within our body.
These are the cells
that have the potential
to become cancer cells.
So by breaking these cells
down, flushing them out
it's actually been shown
that periods of fasting
can extend the lifespan of people.
It also stimulates the
production of stem cells.
So it helps repair the body.
It can kickstart fat loss,
particularly around the abdomen.
That is a very unhealthy type of fat.
It can reduce inflammation
in your overall body
and then it also gives your gut a chance
to basically like flush
everything out, resets everything,
it gives it a rest from
just constantly punishing it
through eating pizza and pasta and oatmeal
and overnight oats and morning
shakes and all these things
that I've been telling
you that you should eat.
And all that said,
I'm not like a fasting is the
best thing out there for ya.
I've actually been fairly
critical of fasting
over the past couple years
thinking that it is
quite a bit of a fad diet
because it comes with a lot of risks.
Number one is that it can
lower your metabolism.
If you do it for a
prolonged period of time
it can make your metabolism slow down
so that when you actually come back
and start eating a normal amount,
your metabolism has slowed down
and not only do you gain back
all the weight that you had before
but you gain back more
and you carry that weight.
There's also the chance of muscle loss.
There's also the risk of it
not actually doing anything,
particularly I look at this
as intermittent fasting.
This has been one of the big woo,
everyone has to intermittent fast.
Well frankly you don't really
get many benefits of fasting
until you get to about 16
hours of fasting total.
So all these people that
are intermittent fasting
and saying like well even
if you give your gut a break
for like 12 hours, 14 hours,
you're really not doing a whole lot.
You're just kinda jackin'
around with your system.
And then finally, for prolonged fasts
there are big sleep issues.
Let's get into the benefits though
of the fast mimicking diet
which is intended to give a
lot of the benefits of fasting
without all of these risks.
So the fast mimicking
diet is a five day fast.
Apparently you get the vast
majority of fasting benefits
around day four to 4-1/2 or five.
Next, you also get a huge
amount of the benefits
from fasting really not by
like fasting, eating nothing.
You get a huge amount of the benefits
just from calorie restriction.
So once you get down to
around 800, 1,100 calories
and you are normally
consuming 2,500 to 3,500
like us endurance athletes are,
you're already getting
a lot of the benefits.
So bringing yourself all
the way down to nothing
is where you start risking
those things like muscle loss.
The fast mimicking diet
starts you off with day one
at around 1,100 calories
and then days two, three, four, and five
you're at about 800 calories.
So let me give you a sense
of what I went through.
On day one I weighed 158.4 pounds.
Throughout that day
I'm keeping the amount of
sugars that I'm having low,
very low glycemic index foods.
So at lunch I'm having things
like chicken broth, nuts.
Dinner, 300 calories,
chicken and spinach salad.
Snacks, I would often have a
small amount of frozen berries
and peanut butter.
Snacks I would also have
a Designs for Health bar,
I stocked up on five of these things.
They're delicious,
kinda stimulates the taste sensation there
but it also really doesn't come
with any like sugary calories.
Now other things that I ate were potatoes.
Potatoes are actually proven
to be the most satiating food.
Basically on a per-calorie
basis you feel the most full
on potatoes beyond any other thing.
Cucumber salad, broccoli and potato soups.
Hot, hot, hot.
Soups made out of low-calorie
but very nutrient-rich things.
Coleslaw and a very light
vinegarette or plain.
Some peanut butter at night,
potatoes and asparagus,
and that's about it.
And let me tell you
that at the end of this,
this morning, five days later,
and I've still got another weigh in
because I'm going to fast still tonight
and then I'll have the
final weigh-in tomorrow
marking the end of the five
days, I was 149 pounds.
Assuming that by tomorrow
I will have lost more than 10 pounds.
So a couple things to keep in mind.
My energy level has been tremendously low.
I have not been training at all.
I'm in the middle of a mid-season break.
The extent of my training
was maybe biking a little bit
to the pool just to pick up my pool bag
for some travel that
I'm doing this weekend.
I went to the bank, I went
and grabbed groceries.
So don't do this while you're training,
you will punish yourself
and you will basically
athletically starve yourself.
Also, you may have a hard time sleeping.
On day three, normally I
take a nap in the afternoon,
could not get to sleep.
Last night day four, could not
get to sleep until midnight.
Make sure that you fill your body
with the bunch of the
nutrients that it needs.
Mega Burn Greens, Mega Burn
protein, Four Sigmatic coffee.

And I put these in the
shakes in the morning
so that basically bam,
right in the morning
I knew that I had enough
nutrients and enough protein
so that I wasn't going
to be nutrient deficient
throughout this and I wasn't
going to be eating into muscle
because I was taking enough protein.
Lots of water to help fill yourself up
and lots of tea to basically
give yourself something to do.
And the results of this, do I
feel okay besides being tired?
Yeah, but physically the
things that I've noticed
are that I am certainly
flatter in the stomach,
I have lost that little bit of,
I've always had a tough time
losing that little bit of fat
right at the bottom of
my stomach, that's gone.
I've noticed a more defined
line down in between my abs
and more in here.
Don't forget, I used to be 215 pounds.
This is not normal.
And this might be TMI
but my poop was black.
That indicates to me you're clearing out
a huge amount of the waste
that's in your digestive system
because you're giving your
body a chance to flush it out.
And of that 10 pounds
I would probably guess
that maybe two pounds of it is fat
but there's a good amount of that poundage
that is really just the body
being able to empty out
the digestive system.
What that's going to allow me
to do is, like I said before,
reset my gut bacteria and this
gives me an excellent chance
to slam a bunch of
probiotics into my system
over the next few days.
And because my gut has been reset
it's going to be very receptive to them
and I'm going to rebuild my
gut bacteria in a good manner.
Am I going to be able to
stay down at 149 pounds?
Probably not, I'm likely
gonna go back up to the 150,
155, 158 but the premise
of this fast mimicking diet
is that you should do it if
you're an athlete maybe tops
twice a year.
It's going to help keep
your weight on the low end
of what's healthy for you.
But if you are say overweight,
if you're carrying 30,
40, 50 pounds or more
you can do this once
every two to three months
until your weight starts getting
down to a healthier level
and then you can start
doing it less frequently.
Credit to a lot of this with
the research of Valter Longo,
but the Longevity Diet book
has been fairly criticized on Amazon
and I would probably echo this
that it doesn't even tell you how
to do the fast mimicking diet,
even though this is the guy
that invented the fast mimicking diet.
It's basically just a sales
pitch for fast mimicking.
Valter Longer also has
a company called ProLon
which supplies all of the food
for the fast mimicking diet.
But you can kinda just piece together
your own fast mimicking diet
with really low-sugar foods,
really nutrient-rich foods, broths, soups,
the things that I told ya here.
So, fast mimicking diet success?
I don't know, we'll have to
see over the next little while.
Fast mimicking diet, lost
weight, felt okay, not that bad.
Does science indicate that
it's going to help me out?
Yeah, is it something
that you should consider?
I don't know but now you know
a little bit more about it.
And tidbit, it ain't pleasant.
When you are somebody that lives and dies
by the calories that they consume,
it's been a tough five days.
Now if you have any questions
about the fast mimicking diet
what you can do by basically
googling Valter Longo podcast,
listen to his podcast,
and that's probably gonna tell you more
than even the book does.
But if you have any questions,
ask them in the comments below
and I'll do my best to
answer them for you.
Alright, later Trainiacs.
