You may have noticed that fat in  areas like the lower back and thighs
is slightly colder to the touch than fat in other areas of your body like the arms
or chest. This is simply because there’s less blood flowing through these areas.

Less blood flow to an area means fewer catecholamines are able to reach
the stubborn fat cells, which means even slower fat loss.

So we have a double-whammy of fat-loss hindrance here: large numbers of
fat cells that don’t respond well to catecholamines and reduced blood flow to
keep the catecholamines away.

Now, how does fasted cardio help?
Well, blood flow in the abdominal region is increased when you’re in a

fasted state, which means the catecholamines can reach this stubborn fat easier,
resulting in more mobilization of it.13

This is where I’ve noticed a difference in cutting with and without fasted
training. When I include fasted training (both cardio and weightlifting), the
journey from about nine percent to six percent body fat, where the majority of
the fat you’re losing is the stubborn stuff, is noticeably faster than when I don’t.


As you know, I’m a big fan of HIIT, both for fed and fasted training.
Some people say HIIT performed in a fasted state is silly, because fat

oxidation rates are much lower during HIIT exercise.
Well, while it’s true that  fat oxidation rates decline as cardio intensity

increases  (as  glycogen  then becomes the fuel of choice),  there’s more to

• Research shows that as you continue to perform regular high-intensity
interval cardio sessions, your muscles learn to use less glycogen during
workouts (thus increasing fat oxidation rates during the workouts),
and your muscle cells also get better and better at oxidizing fats.15

• This latter point is particularly relevant to fasted training as, over time,
HIIT increases the total amount of fatty acids your body is able to
metabolize during workouts.16

• Research  shows that the post-exercise afterburn effect (EPOC) is
greater with HIIT than with LISS cardio (about double, actually: 13
percent vs. seven percent).17

• Research  shows that high-intensity interval cardio is particularly
good for getting rid of stubborn abdominal fat, including dangerous
accumulations of visceral fat.18

Given all the above, I think it’s just a no-brainer to choose high-intensity
interval cardio over LISS, fed or fasted. 


Weightlifting causes a dramatic spike in plasma catecholamine levels, and
as catecholamines are better able to mobilize fat when you’re in a fasted state,
fasted weightlifting is also a worthwhile fat loss strategy.19

I do all of my exercise — both weightlifting and cardio — fasted when I’m
dieting for weight loss. As I said earlier, the stubborn fat disappears faster when
I’m fasted than when I exercise in a fed state.

A caveat, though, don’t be surprised if you’re noticeably weaker during
your first couple of weeks of switching from fed weightlifting to fasted.

You will lose some reps on your big lifts, if not across the board. This isn’t because
you’re losing muscle. It’s simply because eating a significant amount of carbohydrate
before you work out dramatically improves your performance in the gym.20 Take the
carbs away, and you lose the boost. Add them back, and it returns.

That said, as I noted earlier, your body slowly adapts to training in the fasted state,
learning to preserve glycogen stores and thus preserve performance. Nevertheless, I’ve
found that my lifts while fasted are just never as good as my lifts while fed.


Fasted training is a double-edged sword. It’s good for losing fat faster but
not so good for maintaining muscle and enjoying your workouts.

The first problem is that it significantly increases muscle breakdown rates.21

This is undesirable, because if you damage and break down too many
muscle cells in your workouts, your body won’t be able to keep up with repair,
and you can lose muscle over time.

The next problem is lackluster workouts.
Many people find they have less energy and focus when training in a fasted

state and thus aren’t able maintain the level of physical and mental intensity
they’re used to.

Now, most people familiar with how fasted training works use branched-
chain amino acids (BCAAs) to counteract the muscle loss.

This is a workable solution but not my preference.


BCAAs are one of the most popular — and overrated — supplements on
the market today.
