👉 Truth About Intermittent Fasting & Slower Metabolisms

Hi, it’s Dr Sam Robbins,
I recently had a subscriber ask me if intermittent
fasting will slow down his metabolism?…
It’s a good question, since intermittent
fasting is a popular topic these days — AGAIN.
I say “again” because like any fad diet,
it shows up every decade or so, then disappears
and then, repears, … over and over again.
Just like most people’s weight loss attempts
— they keep losing the same weight, OVER
AND OVER again.
Personally, I think intermittent fasting,
just like a ketogenic diet, has lots of health
benefits – IF it’s done correctly.
Unfortunately, most do it all wrong.
YES, they get benefits at the beginning.
But ALL diets work in the beginning.
That’s easy.
The hard part is continue and long-term FAT
And the keyword here is FAT LOSS, not “weight
loss” which is usually valuable muscle.
This is because your body adapts, fat loss
slows down, stops and then reverses.
Some will say “I’m still losing weight”,
which is true – but now they are losing a
lot more valuable muscle, instead of fat.
This is how your body survives.
It’s only goal is to adapt.
And, in the process, your metabolism slows
down in order for you to survive and not keep
losing weight forever.
Two Popular Intermittent Fasting Protocols
There are two popular types of intermittent
fasting, the weekly 5:2.
Which is eating normally for 5 days and then
fasting for 2.
Then there’s the daily 16:8.
Which is fasting for 16 hours and eating for
And people do lose fat and weight because
of this and the primary reason for many is
the fact that they are simply eating less
Which is great.
Yes, intermittent fasting has beneficial hormonal
changes – such as higher Growth Hormone, Testosterone,
Lower insulin levels and so forth… initially,
at the beginning.
But all of that stops working after a few
weeks and months.
However, the improved insulin sensitivity
And I know this because after 30 years, I’ve
seen hundreds of blood tests with all sorts
of various diets.
Not just after a few weeks, but long-term,
such as 6 and 12 months and 2 years later,
when the REAL problems start to show up.
When people’s metabolisms, hormones, thyroid
and so forth have really shut down.
When they’re barely eating anything and
still can’t lose any weight.
They ALL Slow Down Your Metabolism
Simply stated, any diet that restricts calories
too much, too fast and for too long, will
slow down your metabolism.
I know of a few experts and doctors who eat
just ONE meal a day and they brag about how
much weight they’ve lost.
But they’re barely eating 600-1000 calories.
TRUST ME, their metabolisms have shut down,
along with their hormones.
And it shows since they just look skinny fat,
with almost no muscle.
If you want to do intermittent fasting and
still optimize your hormones, I suggest you
Every 6-12 weeks, take 3-7 days off and eat
normally and increase your calories by 10-20%.
This will jump start your hormones, and reboot
your system.
If you feel the fat loss has stopped for a
couple of weeks, that’s a clue to stop,
refeed extra calories and then, start again
with the diet.
For some, this happens faster and sooner than
Remember, it’s all about your hormones.
Your body will adapt by turning off your fat-burning
IT will sense mild starvation and will do
its best to preserve fat and start burning
muscle slowly.
It will for sure, increase cortisol levels
and other stress hormones, which TRUMPS all
other hormones — Growth Hormone, testosterone,
insulin, IGF, etc.
So, there you have it – cycle this and any
