| If you want to lose weight, don't over-exercise |
You
will lose weight properly with a methodical and not too much exercise
Overtraining occurs when
there is an imbalance between the amount of exercise you do and the amount of
recovery you have between training sessions. It can cause impaired immune
response, altered hormonal activity, and persistent fatigue (usually lasting
more than four weeks). But some reports and online commentary also suggest that
overtraining may be the reason why some people are struggling to lose weight -
or it may even cause them to gain weight. This is unlikely - here's why.
Not only is recovery
important for those looking to build muscle, leaving enough time to recover
between workouts is also important to avoid "overtraining" - a form
of extreme fatigue that can be overwhelming. Recovery can take weeks to years.
To lose weight, you must
create what is known as a “calorie deficit”. This basically just means burning
more calories than you're taking in and for a sustained period of time.
There are two ways to
reach a calorie deficit - whether it's changing your diet so you eat fewer
calories than your body burns, or increasing your exercise intake so you burn
more calories than you're taking in. into the.
On this basis, it seems
realistic to expect that if someone over-exercises they will probably burn more
calories than they are taking in - leading to weight loss. But some people
believe that because exercise puts a strain on the body, overdoing it will put
long-term stress on the body - which in turn leads to weight gain. This
counterintuitive link is often related to a hormone called cortisol.
The hormone cortisol is
often released in response to stress - such as emotional stress from work or
school. Cortisol is also released when we complete moderate or intense exercise
stress. The body does this to help prepare for the stress it will experience -
so it requires the body to release some energy to help complete whatever
exercise we're doing.
The stress-related
increases in cortisol levels associated with exercise are usually short-lived
and usually return to normal within an hour of exercise. As a result, anyone
who regularly exercises at a high level will experience persistently elevated
cortisol levels due to exercise-related stress.
Your
stress and weight need specific understanding
Overexposure to cortisol
leads to increased activation of a particular enzyme called lipoprotein lipase
that exists in fat cells. This enzyme tells cells to increase fat storage and
explains why excessive stress can sometimes lead to increased fat in the
abdomen, face and chest area. Excessively high levels of cortisol can also make
it easier for adipose tissue to regenerate cortisol in the adipose tissue
itself - further increasing lipoprotein lipase activity and subsequent fat
storage.
Research from my own lab
has found that the cortisol response to a high-intensity stress test, 30-minute
cycle exercise is reduced after a short period (11 days) of exercise. high
amtitude. This, along with findings from other research, suggests that during
periods of overtraining, our blood cortisol levels can actually drop in
response to a stressful event - for example. like exercise.
There is some evidence
that the group of cortisol-producing glands (called the HPA axis) is affected
by overtraining. But much of this research shows that cortisol's response to
stress is actually reduced during periods of overtraining.
This may be a protective
mechanism for the body when it is repeatedly exposed to increased levels of
cortisol. This means that a period of intense exercise is unlikely to increase
fat storage and weight gain.
An
average person's rate of overtraining
Even if you exercise
regularly, it's hard to know your risk from overtraining. We know that advanced
athletes are more likely to be overtrained due to their intense training needs,
with studies showing that between 30% and 60% of athletes overtrain. . But
research looking specifically at how often the average person experiences
overtraining is rare.
So why can people experience
weight loss even if they are exercising regularly? While the hormone cortisol
has been linked to weight gain, the average person exercising a few times a
week is unlikely to stress their bodies enough to cause the type of cortisol to
spike significantly and sustainably. to do this.
If you have been
successful in losing weight but find that your progress has stalled, then you
should calculate if you now Do you need fewer calories? Adding some extra light
activity every day - such as a lunchtime walk - can also help you burn some
extra calories without stressing your body.
The reason people may
experience weight loss - or even weight gain - despite going to the gym a few
times a week or even daily can be due to any number of factors. Excessive
stress in your day can be a cause, along with a poor-quality diet, of not
running into a calorie deficit or even overestimating the number of calories
you burn in the gym.
While overtraining
shouldn't stop the average person from losing weight, it's important to incorporate
rest days into your exercise routine to avoid fatigue and allow your muscles to
recover.
