what is polycystic ovary syndrome and
0:02
can nutrition help let's talk about that
0:07
how's it going guys my name is richie
0:09
kirwan and today we're going to talk
0:10
about one of the most common conditions
0:14
affecting women that you've never heard
0:15
about polycystic ovary syndrome or pcos
0:18
so if you've never heard of pcos before
0:20
that's not surprising but what is
0:22
surprising is that affects almost
0:24
one-fifth of women of reproductive age
0:27
making it the most common hormonal
0:29
condition in this group what's also
0:30
surprising is that pcos is one of the
0:33
leading causes of an ovulatory
0:35
infertility in women and still very few
0:37
people know about it hopefully we can
0:39
change that a little with this video now
0:41
before we go any further i just want to
0:42
point out that in this video we're not
0:44
offering any diagnosis or claiming any
0:47
treatments for pcos if you suspect you
0:49
might have pcos go to your doctor and
0:51
get a proper diagnosis and treatment
0:54
what we are going to do in this video is
0:56
talk about what it is how pcos can
0:59
affect health and offer some lifestyle
1:01
based nutrition and exercise
1:03
recommendations that can help support
1:04
women with pcos to live a healthier life
1:08
i also want to say a big thank you to
1:10
both georgia kohlhoff and dr emilia
1:12
thompson who gave me a huge amount of
1:14
input on some of the nutrition and
1:16
exercise strategies for pcos that i'm
1:18
going to talk about here so pcos is a
1:20
condition that results in alterations in
1:23
hormone production in women but because
1:24
it's a syndrome or a group of different
1:26
symptoms that can often associate
1:28
together it often can look very
1:30
different in different women the most
1:32
common groups of symptoms which are
1:33
associated with pcos are
1:35
hyperandrogenism which means an excess
1:38
production of testosterone which can
1:39
lead to hirsutism or excessive hair
1:42
growth and even male pattern baldness in
1:44
someone insulin resistance which is a
1:47
reduced ability of the body to respond
1:49
to the insulin that we produce this is
1:51
often associated with poor glycemic
1:53
control or blood sugar control and it
1:55
leads to a greater risk of obesity
1:57
diabetes and even cardiovascular disease
2:00
chronic irregular ovulation which can
2:02
manifest as irregular or painful periods
2:05
and can be linked with infertility and
2:07
finally polycystic ovaries which means
2:09
having a lot of cysts in the ovaries to
2:11
be diagnosed with pcos you may only need
2:14
any two of the symptoms which i've just
2:16
mentioned which means you can have
2:17
polycystic ovary syndrome without
2:19
actually having polycystic ovaries and
2:21
you can have polycystic ovaries without
2:23
having pcos if all of that doesn't sound
2:26
particularly pleasant it isn't so
2:28
managing symptoms effectively through
2:29
diet and exercise can be really
2:31
important for women with pcos so let's
2:34
start with one of the most common
2:36
manifestations of pcos and that's excess
2:39
body weight it turns out that women with
2:40
pcos are much more likely to be
2:43
overweight or obese compared to women
2:45
without it now that said there is a type
2:47
of pcos called lean pcos where women can
2:50
have the other symptoms of pcos but
2:52
while maintaining a normal body weight
2:54
for women with pcos and obesity losing
2:56
some excess body weight can be
2:58
beneficial and some studies show
2:59
improvements in hirsutism insulin
3:01
resistance and circulating androgen
3:03
hormones like testosterone in fact a
3:05
number of studies have shown that
3:06
reduced calorie diets and weight loss of
3:08
about five percent of body weight can
3:09
lead to improvements in the regularity
3:11
of periods and even fertility in some
3:13
women with pcos now there's a couple of
3:15
reasons for that that are worth
3:16
mentioning here the first is the fact
3:18
that women with pcos can have a much
3:21
lower metabolic rate than women without
3:23
it in fact one study found that women
3:25
with pcos and insulin resistance can
3:29
lower basal metabolic rate than women
3:31
without pcos and insulin resistance in
3:33
the same study women with pcos but no
3:36
insulin resistance had higher bmrs than
3:38
that but lower bmrs than the general
3:41
population that is a huge difference in
3:43
metabolic rate which means it can be a
3:45
lot easier for women with pcos to gain
3:47
weight eating the normal recommended
3:49
daily amount of calories for women
3:51
without the condition that means women
3:53
with pcos may need to be a little more
3:56
conservative with calories compared to
3:58
the general population to make matters
4:00
even more difficult there is evidence
4:02
that the increased levels of
4:03
testosterone in women with pcos can
4:05
affect satiety hormones like ckk meaning
4:08
those women have an increased appetite
4:10
and food cravings and are more likely to
4:13
have a tendency to binge eat as well so
4:15
what can you do practically to help with
4:17
weight reduction in pcos all the
4:19
principles of calorie deficits still
4:21
apply in people with pcos so i'd really
4:23
recommend checking out my video on how
4:25
to plan a calorie deficit the only
4:27
difference like i've already mentioned
4:28
is that someone with pcos may need to be
4:31
more conservative with calories this is
4:33
where food choice can be hugely
4:35
important if you've watched a few of my
4:37
videos you'll know that one of the most
4:38
important factors for long-term weight
4:40
loss is being able to stick to a diet
4:43
long term one way to help you stick to a
4:45
diet is to eat foods that help keep you
4:47
feeling full and that keep hunger at bay
4:50
firstly get plenty of protein at each
4:52
meal protein is the most filling
4:54
macronutrient and helps keep hunger at
4:55
bay for longer aiming for at least 30
4:57
grams of protein per meal is a good rule
4:59
of thumb next eat plenty of low calorie
5:02
density high volume foods like fresh
5:05
fruit and vegetables these keep you
5:07
feeling full and have very few calories
5:09
to help keep your overall calories low
5:11
that can be as easy as aiming for at
5:13
least two servings of fruit or veg with
5:15
each meal stick to high fiber foods or
5:17
high fiber versions of foods fiber can
5:20
keep you feeling fuller for longer by
5:21
absorbing water in your digestive system
5:23
and slowing the emptying of food that
5:25
means foods like fruits vegetables whole
5:28
grains like whole wheat products and
5:30
oats and legumes like beans peas and
5:32
lentils can help keep you feeling fuller
5:34
for longer this type of eating plan
5:36
based mostly around whole foods will
5:38
also have a low glycemic load meaning it
5:40
will have smaller effects on your blood
5:42
sugar which may have some benefits in
5:44
pcos for helping to improve insulin
5:47
sensitivity you may also hear a lot of
5:49
sources online say that you need to
5:51
eliminate carbohydrates and go keto if
5:53
you have pcos that's simply not true
5:56
while a keto diet is absolutely fine if
5:58
you like eating that way and it can help
6:00
you with weight loss in pcos there is no
6:02
reason that you need to do it you you'll
6:06
of people mention a lot of pretty
6:08
extreme diets that they claim you'll
6:10
need to follow if you have pcos they
6:12
might say you need to go gluten-free or
6:14
avoid dairy cut out sugar or go
6:16
completely carnivore on one extreme or
6:18
vegan on the other it's all but
6:20
because food cravings can be higher with
6:22
pcos allowing yourself some of the foods
6:24
that you crave like carbs for example in
6:27
moderation can be a good strategy to
6:29
help you maintain an overall healthy
6:32
diet that said because calories can be
6:34
lower for people with pcos that means
6:36
that overall carbs may be lower too as
6:39
you'll want to make sure you're getting
6:40
enough protein and sufficient fat in
6:42
your diet in that case it might be a
6:44
good idea to bunch your carbs together
6:46
to make a more enjoyable meal while
6:48
other meals might be lowering carbs
6:49
bunching those carbs around your
6:51
workouts either before or after might be
6:53
helpful too for fueling your workouts
6:55
properly or improving recovery depending
6:57
on when you have your carbs in
6:59
particular bunching your carbs earlier
7:01
in the day can be beneficial because we
7:03
naturally are more insulin sensitive in
7:05
the mornings which brings me to my next
7:07
point besides diet exercise can also be
7:10
really important for women with pcos a
7:12
combination of aerobic and resistance
7:14
exercise can not only reduce insulin
7:16
resistance but it can also raise resting
7:19
energy expenditure which i've already
7:20
said can be low in women with pcos on
7:23
top of that resistance exercise and
7:25
exercise in general can help to reduce
7:27
the risk of many of the health
7:29
conditions associated with pcos like
7:31
cardiovascular disease and diabetes
7:33
what's really impressive is that
7:34
exercise can have many of these health
7:36
promoting benefits even without any
7:38
weight loss which is yet another reason
7:41
to make exercise a regular habit getting
7:43
at least 30 minutes of moderate to high
7:45
intensity exercise daily is recommended
7:48
for health and if you can add some
7:49
resistance exercise like weight training
7:51
two or three days a week that can help
7:53
maintain healthy muscle and strength
7:55
levels too i talk all about the benefits
7:57
of muscle as we age in my past videos
7:59
too so check them out for more
8:00
recommendations now while i've been
8:02
talking a lot about weight loss for pcos
8:04
it's also worth mentioning that women
8:06
who have lean pcos meaning they don't
8:09
have a lot of excess body fat shouldn't
8:11
aim for weight loss instead they can use
8:14
a lot of the diet and exercise
8:15
strategies i've just mentioned while
8:16
maintaining their healthy weight losing
8:18
weight may not be helpful in lean pcos
8:21
besides diet and exercise there are some
8:24
supplements that might be really useful
8:26
in pcos without a doubt the most
8:28
exciting evidence for supplements and
8:30
pcos is for inositol or specifically
8:32
myo-inositol this is because there have
8:34
been a lot of studies showing that
8:36
inositol can help with the insulin
8:38
resistance that is common in pcos
8:40
inositols are substances that are
8:42
naturally produced in our cells but
8:44
because of the hormonal disruptions in
8:46
pcos they can be metabolized slightly
8:48
differently in pcos supplementing with
8:50
anastasia can increase insulin
8:52
sensitivity reduce androgen hormones in
8:54
the blood improve blood sugar control
8:56
and even help bring back normal
8:59
ovulation and periods and even fertility
9:01
inositol seems to be a very safe
9:04
supplement to take so current
9:05
recommendations are two grams of
9:07
myonosatol twice a day so four grams in
9:10
total another supplement that might be
9:11
worth considering is berberine berberine
9:14
is a compound found in the roots of some
9:16
plants that are commonly used in herbal
9:18
medicine for women with pcos
9:20
supplementing with berberine seems to
9:21
have many of the same benefits of
9:23
myoanasta that means it can improve
9:25
insulin sensitivity reduce levels of
9:27
androgens in the blood improve blood
9:29
lipids like cholesterol and
9:30
triglycerides and even help to reduce
9:32
chronic inflammation which can be seen
9:34
in pcos in fact some evidence suggests
9:37
berberine may be as effective as
9:39
metformin a drug used to improve insulin
9:42
sensitivity in people with diabetes and
9:44
women with pcos a berberine dose of 500
9:46
milligrams three times a day for a total
9:48
of 1500 milligrams may be useful another
9:51
interesting fact is that women with pcos
9:53
tend to have lower levels of l-carnitine
9:56
a molecule involved in fat metabolism
9:58
and levels tend to be even lower in
10:00
women with pcos and higher levels of
10:02
body fat and more insulin resistance
10:04
because of that supplementing with
10:05
l-carnitine may actually be useful for
10:08
women with pcos by helping to improve
10:10
insulin sensitivity reduce body fat
10:12
improve hormone levels and even restore
10:14
a more regular menstrual cycle we still
10:17
need a lot more evidence before we can
10:19
say it's definitely effective but it may
10:21
be worth trying a dose of 1000 to 1500
10:24
milligrams twice daily and just on a
10:26
final note you'll know that i recommend
10:28
long-chain omega-3 supplements like fish
10:30
oil or algal oil for general health
10:32
especially cardio metabolic health
10:34
because women with pcos have a greater
10:36
risk of diabetes and heart disease it
10:37
may be worthwhile taking a long chain
10:40
omega-3 supplement too fish oils have
10:42
been shown to improve risk factors like
10:43
insulin resistance cholesterol and
10:45
triglycerides in women with pcos a good
10:47
daily dose to aim for is about 1 000
10:49
milligrams of combined epa and dha the
10:51
most bioactive omega-3 fatty acids found
10:54
in fish oils or if you're vegan in algal
10:56
oil supplements we really have covered a
10:58
lot in this video if you have pcos
11:00
yourself you'll know how hard it can be
11:02
dealing with the symptoms like i've
11:04
already said speaking with your doctor
11:06
should be your first port of call in
11:08
helping you to manage it on top of that
11:10
i really hope that the lifestyle and
11:12
supplement recommendations i've just
11:13
gone through here might be able to help
11:16
alongside the medical treatment you
11:17
receive as always if you have any more
