Something Crazy Happens When You Lift Weights While Cutting - Dr Mike Israetel
Watch on YouTubeVideo summary
During a fat loss protocol, resistance training plays a critical role in preserving muscle tissue while dieting, even though it does not burn an excessive number of calories on its own. Without consistent weightlifting, individuals losing significant weight—such as 15 pounds over twelve weeks—are likely to lose roughly half that amount as muscle mass and the rest as fat. In contrast, those who maintain a resistance training regimen can expect nearly all their weight loss to come from adipose tissue, retaining only about two pounds of muscle while shedding thirteen or more pounds of fat. This distinction is vital because regaining lost muscle after stopping exercise takes time; however, continuing to train ensures that the majority of the scale change reflects actual body composition improvement rather than mere dehydration or metabolic slowdown. The most transformative aspect of combining weightlifting with a caloric deficit occurs for beginners who are losing fat for the first time while simultaneously starting resistance training. In these scenarios, it is entirely possible—and often beneficial—to gain muscle mass at the same time as burning fat, debunking the myth that one cannot do both concurrently. A prominent example cited involves UFC President Dana White, whose dramatic physical transformation included a loss of approximately 35 pounds on the scale while gaining an estimated five to ten pounds of lean tissue through rigorous weight training and dietary cleanup. This shift not only improved his health markers but also altered his appearance from looking unhealthy or "opulent" in a negative sense to appearing vital, strong, and athletic, demonstrating that significant aesthetic changes are possible without becoming overly muscular like bodybuilder Arnold Schwarzenegger. For women specifically, particularly those over forty who may worry about gaining excessive muscle mass while lifting weights, the reality is far less daunting than popular culture suggests. Biologically, females have significantly lower levels of testosterone compared to males and would require extraordinary circumstances—such as having serum testosterone at two orders of magnitude higher—to accidentally transform into a hyper-muscular physique like Arnold's within days or weeks. Instead, consistent weightlifting during a diet helps women maintain muscle shape, improve their posture, enhance the definition of their legs and glutes, and project an image that looks healthy rather than sickly or emaciated. This process creates a positive feedback loop where individuals feel stronger, look more attractive to themselves, and experience improved vitality, effectively reversing the feeling of weakness often associated with strict dieting alone. Regarding training specifics during a deficit, most people should continue their standard resistance routines without major adjustments unless they are in an extreme fat loss phase typical of competition bodybuilders. For advanced athletes nearing peak leanness, slight modifications such as reducing load and increasing repetitions can help maintain muscular endurance while minimizing injury risk, though this is rarely necessary for the general population. The primary challenge during a diet is managing fatigue; strength gains may plateau or decline slightly, but training volume must remain high to counteract the catabolic environment created by caloric restriction. If an athlete trains too easily under these conditions, they will lose muscle despite their efforts, whereas pushing limits within recovery capabilities allows them to maintain mass and potentially gain a little more. To navigate declining strength progressions during a cut, athletes should adjust expectations from adding five pounds every week to aiming for smaller increments like two pounds or one rep per session as fatigue sets in over weeks four through twelve of the program. The goal shifts from rapid hypertrophy to maintaining current levels while fighting against muscle loss; if an athlete trains with reduced intensity because they are tired, they risk losing ground entirely. Conversely, attempting to train at pre-diet intensities often leads to burnout and deloads every third week. By anticipating slower progressions and focusing on testing limits safely within recovery windows, individuals can successfully preserve their hard-earned muscle while shedding fat, ensuring that the final result is a leaner but stronger version of themselves rather than a weaker one.

what about the role of resistance
training during a fat loss protocol
super resistance training doesn't really
help you lose weight uh it does in the
sense that it burns calories but it
doesn't burn a crazy amount of calories
it's a good amount but nothing to and
say resistance training builds and
preserves your muscle tissue so if I
have someone lose 15 pounds over the
course of 12 weeks reasonable for a
larger sized person they don't
resistance train at all many of the OIC
studies showed something like this
they'll lose like you know half of that
will be muscle maybe five pounds will be
muscle 10 pounds will be fat if you're
lucky you're healthier you look better
your blood work is better you feel
better it's not
amazing if you resistance train and
you've been resistance training
consistently already
almost all of that weight loss will be
fat maybe like 13 lounds of it and only
two pounds of lost muscle and because
you keep resistance training after you
regain that two pounds back like three
weeks later and then so measured at 3
weeks after you finish that 12we diet
you lost well 13ish pounds of fat and no
muscle visually healthwise feeling wise
night and day here's a real kicker if
it's your first first time losing fat
and you don't train with weights
starting to train with weights while you
start to kind of clean up your diet and
lose a little fat you can gain pounds of
muscle while losing pounds of fat I
thought it was impossible to lose fat
and gain muscle at the same time yeah a
lot of people uh misinterpret more
difficult than average to mean
impossible it's like saying flight is
impossible and that a helicopter goes by
like [ __ ]
[ __ ] so really good example of this
recently in the media was uh UFC
president Dana White Dana White had an
unreal transformation as health markers
just through the roof and I think he
lost something like a total of maybe 35
PBS on the scale but because he started
taking weight training very seriously
during that time he must have gained
anywhere from five to 15 lounds of
muscle I mean 15's a bit extreme but I'm
willing to go 5 to 10 for sure just
guessing and that means he actually lost
maybe 45 pounds of
fat while gaining muscle so he didn't go
from with all total respect looking like
geez is Dana gonna be
okay not really gez Dana's really
enjoying his wealth kind of look yeah it
was that opulent weight my man that
Caesar type of [ __ ] other people feed
yeah the the biggest concern is gout
exactly oh
again so is this something wine can cure
Jesus he went he could have gone from
that with no resistance training to like
oh Dana White lost weight and that's
nice to hear but he went from that to
like yo what the [ __ ] Dana is Superman
when the hell is he getting in the
Octagon you feel me that's a big deal
it's a big deal at Deep Health markers
it's a big deal at how you feel some
people feel weaker after a diet cuz they
are they lost a bunch of muscle you gain
muscle or maintain it through a diet you
feel stronger after a diet and the look
and since I'm on the modern wisdom
podcast I can say this and it's fit for
purpose how attractive you are to
yourself [ __ ] everybody
else
matters and if you lose exclusively or
mostly fat [ __ ] even gain some muscle
during that time you transform your
attractiveness in most cases up a bunch
of notches it's a positive feedback
cycle for yourself as well as opposed to
going from God I was overweight to H
well I'm not overweight anymore but I'm
not I look sick yeah yeah emaciated and
and look most people prefer bodies that
are smaller and Slimmer that's just a a
statistical fact but even more people
prefer fit bodies for the themselves and
definitely for other people so if you
resistance train when you're losing
weight and yes this is a message to
almost all modern women that are in
their 40s and 50s get in the weight room
lift weights hard get a good personal
trainer download the RP hypertrophy app
link in BIO what was I did I just say
something and while you clean up your
diet while you lose fat what you can do
is see a completely transformative
effect and know you will not turn into
Arnold Schwarz [ __ ] by accident
overnight I mean I used to be
biologically female and 120 lbs body
weight yesterday and it took one day for
me to do this dude that's the my
favorite scop is the one that women give
to themselves which is if I lift weights
I will become too jacked meanwhile those
of us that have desperately been lifting
weights for approaching two decades now
in the hopes that one day I might look
remotely like I do someone will be able
to tell I work out at the store I'm like
the chance that you're going to wake up
one day and become an given how hard me
and all of my friends have worked at
doing that and he still not achieved it
is zero it's you don't need to worry
it's real close to zero uh it's one of
these things where they're doing it at
like two orders of magnitude less serum
testosterone as well all women are
hypogonadal if you're a female and you
show up the doc and you're like heyy my
testicles don't produce testosterone
he's going to do blood work he's like oh
my God you're right you have almost no
testosterone you're not the candidate
for rabid muscle growth what's going to
happen is you're going to diet down and
you're going to look less like you're
sick at the end and more like you look
healthy and vital and like a little
young B bopper like you know when
younger women almost don't walk they
kind of just bounce around that like
[ __ ] they have you can have that it's
called muscle mass it changes the shape
of your body it does this to your ass it
makes your legs look awesome it does
everything wonderful and it does not
turn you into Arnold schwarzer overnight
it's a huge deal are there any specifics
when it comes to training during a fat
loss phase resistance wise we did a
great breakdown that everyone can go and
watch on how to train for muscle growth
are there any adjustments when you're in
a
deficit for most people
no if you are at the very end of it uh
insane fat loss phase if you're a
competition bodybuilder you might want
to try to reduce the amount of load
you're lifting by a little and increase
the repetitions just because it's the
same hypertrophic drive on average but
uh you're marginally reducing the risk
of injury by a tiny little bit it's also
through some bio biochemical mechanisms
easier to maintain your muscular
endurance and improve it as you're
dieting down than it is to maintain or
increase your strength and so that is
like a very exotic concern for almost
everyone is just kind of the same
resistance training as we talked about
on our earlier video all the time should
people be trying to increase the weight
and the Reps that they're doing as they
go through fat Los should they have it
in the back of their mind ah I might get
a bit tired you know I'm four weeks in
I'm 8 weeks in I'm 12 weeks in uh about
dealing with the mental pain of maybe
not being the progress of strength not
going in quite the the direction
question the RP hypertrophy app does
that for you Mike seriously shot the
hell up about your stupid apps uh
um you should anticipate that the rate
of progression is going to
decline maybe you've been really gunning
it for a while and adding five pounds to
the bar and everything every week and
when you're not adding weight you might
be able to add two reps to the
exercise especially at the tail end of a
fat loss phase try to aim for adding 2
and 1 12 pounds to the bar every week
and maybe adding a rep every week or if
you're pretty Advanced and things really
slow down every other week go up by 2
and2 PBS or a rep and every other week
just maintain and so instead of trying
to gain at a fast rate you're trying to
either gain at a very slow rate and in
the end you win some you lose some and
you end up maintaining but you still got
to try to push it what you don't want to
do is start trying less hard to really
take it to the teeth when you're in a
fat loss phase because the total
catabolic muscle destroying muscle
burning stimulus is high as [ __ ] now you
got to fight against it by keeping your
training volume up of course within the
ability to recover which is going to
decline you still have to test your
limits a little bit because if you train
easy and you diet really hard for fat
loss you might lose some muscle still if
you train as hard as you're capable of
you might lose no muscle and maybe gain
a little if you train or try to train as
hard as you were when you were massing
you'll just overreach and have to de lo
every third week and that might not be a
fun experience in other news this
