Cardio World Ep10: Carbs, Protein, and Fat…Oh, MY!


Hey, I’m Alicia Marie… …and welcome
to my “Cardio World.” I just want to say thanks to everyone
who keeps tweeting me questions. Please keep them coming,
thank you very much,… …they make the show. Let’s get started
with today’s questions, shall we? Why are all you fitness freaks
always talking… …about fats,
proteins and carbohydrates? No one knows what the heck you people
are talking about by the way. Okay, thanks, bye. I don’t see any freaks anywhere… …but I was actually hoping that
someone would ask me to break it down. Okay, tweeper, every human body
requires a specific ratio… …of nutrients for growth,
metabolism,… …immune system functioning,… …body tissue repairs
and for overall good health. Three of these essential nutrients
provide calories… …and are needed for energy
so you can move. We need these in larger amounts,
they’re called… …macronutrients. Carbohydrates
are the body’s main source of fuel. We need carbs in the largest amounts… …in order for our brain, muscles
and kidneys to function properly. Carbs can be stored in our muscles
and liver and used later for energy… …but for fast energy
reach for the good carbs… …that are found in whole grains,
sweet potatoes, oats… …or for the fabulous carbs
found in fibrous beans, nuts, fruits,… …and veggies,
but don’t get too excited. That factory made cupcake
that you’re still thinking about,… …it’s full of carbohydrates,
the bad kind… …and sugar processed everything,… …the stuff your body doesn’t like
even though your tummy does. Todd, do not listen to Alicia,
just eat that,… …put it all down here, oh God! Hush you, it’s a vicious cycle. Those kind of easy carbs
cause your blood sugar… …or insulin levels to rise
only to crash soon after. Hey, send some food down here,
why is that so hard? Oh, send down more of the bad stuff,
it’s full of all of this cosmic garbage. Okay, okay, I get it, I get it. Don’t eat bad carbs, my body
doesn’t know how to break down. Too many bad starchy, high-sugar carbs
like cold cereal, candy bars,… …pizza, potato chips
and gummy patch kids… …and you’ve just programmed your body
to store a few extra layers of fat… …which brings me… …to the most underappreciated
member of the macro club, fat. You’re probably wondering… …why I’m trying to convince you
that your body needs fat. Well, it does, just not
as much as you think… …nor as much as you humans —
we humans carry. Fat is the body’s most concentrated
form of energy. It’s basically
your body’s emergency storage. Fat is necessary for cushioning
for your organs, for growth,… …for development… …and for the absorption
of various vitamins. Behold Mr. Fatty! Just like carbohydrates, there are
the good the bad and the ugly of fats. First, Todd, there are the good fats… …or monounsaturated fats
like the ones found in fish,… …avocadoes, nuts,
olive oil and flax,…. …are good for you
and they can help you burn fat… …and reduce the risk of heart disease.
Fat does not make you fat. Consuming more calories
than you burn off makes you fat. -Got it?
-Yeah, I got it. If I’m eating more
I better exercise more… …because I need
to burn calories, got it. Second, we have the bad fats. They are saturated like the ones
found in high-fat marbled meats,… …cream, butter and lard. Your liver makes cholesterol,
an artery clogging type of fat. Wait — my liver makes fat? Yes, from fatty foods you eat. I thought my liver was detoxifying
the booze I drink. No, pay attention. Most fatty acids exist
as straight chain hydrocarbons… …that attach to carboxylic acids… …frequent an even number
of carbon atoms. Fatty acids are
structurally simple and rigid… …unlike their double bond
more flexible sister,… …saturated fatty acids tend
to be solid at room temperature… …with their melting points
increasing… …with a chain length
tempo composition CH3,… …CH2, COOH or Lauric Acid. Oh, what? They’re just bad fats. And finally,… …we have the ugly fats. -That’s funny to you?
-What…? Everybody has a twin Todd. These are the hard fats which will clog
your arteries and pad your belly. Trans fats are found in packaged
baked goods, snack foods,… …shelved items… Anything that can live on a shelf
for six months or more… …can live on your love handles
even longer. Your body does not know
how to process this stuff… …so it goes straight
to your storage unit, Todd. This was not funny. And now I’ve saved my personal favorite
macronutrient for last. Protein! Found in meat, poultry, fish, cheese,
tofu, milk, eggs, beans and nuts. They’re essential for growth,
hormonal development,… …that’s important,
and for preserving lean muscle mass. When we eat foods
that are protein rich… …our bodies
can then break it down… …into what are called
amino acids or molecules… …that our body can then read,
understand and use to create muscle. A really large part
of living a fit life… …is knowing how the stuff you put
in your body works with your body. Whenever you eat something,
think to yourself,… …how will my body break it down?
