Low Carb (Ketogenic) Dieting: Part 2
Today I’m going to get started without all the preamble, and
just get right to it. I’ll discuss the
three types of nutritional energy, and address two of the areas from my lastpost:
- · Why you want to keep your fat intake high, and why the type of fat you choose makes a difference.
- · Why you want to keep your protein intake moderate, rather than high—the dangers of too much protein.
Carbohydrates, Fats, and Protein
Carbs, fat, and protein are the only dietary sources of
energy that your body has at its disposal, and like grades of gasoline for your
car, you have a selection: high test, mid grade, and the cheap stuff. Also, like your car, your body will run on
the cheap and mid grades. For a while. We also know about the knocks, pings, and
overall reduced performance of the cars getting the lesser qualities. Now, if that car were a high-performance
vehicle, like a Porsche, you wouldn't dream of putting the cheaper fuels into
it, right? Well, why then, would you
choose the cheaper sources of fuel for your most precious bit of
equipment? I’m talking about your body.
Sure, your body can, and will, use carbs as a source of fuel—and
will even re-tune itself to use them almost to exclusivity—but that’s only
because we shovel so many of them in each day.
I think of carbohydrates as being the lowest quality of the
fuels. It is the only source of dietary
energy that is completely optional. If
you think I’m full of it, check out the studies done on the Inuit people. They gorge on fat, rarely see a vegetable,
and their protein intakes are moderate, yet they are among the healthiest,
tallest, and strongest people (as a whole) than the carb eaters. What’s really telling, though, is that those
who have moved away, so that they’d be closer to towns, etc., and have adopted
a more “heart healthy” diet, are getting just as fat and sick as the rest of
us. (Patricia Gadsby, 2004)
In fact, most indigenous cultures that did not utilize
agriculture, were notably taller and had better muscle development than their
counterparts who raised vegetables and grains.
Their diets consisted almost entirely of fat and protein. They consumed roots, nuts, and seeds. They ate berries and wild fruits when they
were in season. Everything they ate was,
according to the gold standard of eating--local, fresh, and seasonal. These nomadic people hunted and
gathered. Their health, including
dental, was better than what we see today in the modern world. (Enig, 2000)
The literature, research, and published studies are so
numerous—overwhelming, in fact—that support the consumption of fat in favor of
carbs, yet we are still being told to eat carbs and cut the fat out. Why?
Well, carbs are cheap.
Grains are cheap to grow, easy to produce, and fill a lot of bellies for
a lot less money and time than it would take to raise enough animals (properly)
to feed the whole of the world. This is
a conundrum. Is it better to have a
world with a small population of healthy people, or a large population of sick
people? You really don’t want my answer. Suffice to say that I can’t save the whole
world, and neither can you—but we can save ourselves.
I know, and I’m fond of saying, none of us is getting out of
this alive. That doesn't mean I have to
suffer, needlessly, before I check out, though.
The older I get, the more determined I am to not become one of the
zillions of seniors taking handfuls of prescription drugs every day—most of
which are to combat the effects of their diet—when the prescription for health
and vitality just happens to be the foods I choose to eat.
So, we have our cheap fuel—carbs—what about our
mid-grade? Protein. This is where a lot of problems and
disagreements come—even among us Paleo folks.
Some say high, others say moderate.
I’m in the latter group. Whether
you are trying to lose fat, gain muscle, or simply maintain your weight, your
protein needs remain the same. Yes, you
read that right—they stay the same. The following chart shows the minimum recommended amount of protein needed by gender/age group.
Remember, this table shows the absolute barest amount of protein required each day. This would be for normal people, of normal weight, and low activity levels. That's probably you. However, athletes and really large people need to up their protein. This, taken from bornfitness.com, will help to give you a better idea of where you need to be:
- The base level (assuming no activity and no desire to change body composition) is around 0.8g per kilogram body weight (50g for a 137.5lb person) or above. More is not harmful, but this seems to be the bare minimum
- An athlete or highly active person, or a person who is sedentary and looking to lose body fat would do well with a range between 1-1.5g per kilogram. For a 200lb person, this equates to 91-136g daily
- An athlete or active person who wishes to beneficially influence their body composition (lose fat and/or gain muscle) or a very highly active endurance athlete should be consuming in the range of 1.5-2.2g per kilogram daily (for our 200lb person, this equates to 136-200g daily)
Each individual, depending on height, age, and lean body
mass, requires a certain amount of protein.
The amino acids in protein rebuild muscle, organs, cells—everything. Without enough protein these constantly
occuring repairs cannot take place. Too
much protein? Well, it’s essentially
going to undergo a process called gluconeogenesis, which means it’s going to be
converted to sugar, have a mild impact on your insulin, and then get stored as
fat. (Phinney, The Art and Science of Low Carb Living,
2011)
Good sources of protein are shown in the table below:
As you can see, you really don't need to eat a whole lot of meat to get sufficient protein.
One of the primary reasons so many people do so well on a
ketogenic diet is because they aren't constantly overwhelming their insulin
with all the carbs. So, why would you
want to over consume protein if it’s just going to do the same thing? Granted, it’s not as severe as with carbs,
but it does happen. This is also why I
believe so many people fail on ketogenic diets.
They hit a stall (and everyone will), and they immediately cut the fat
and bump up the protein. Bad choice. My suggestion to you is this: if the diet was
working and you haven’t changed it before you stalled out, leave things alone—plateaus
are a natural part of the process. I've read accounts of people hitting a stall of ten or more weeks before they broke.
I discussed this very issue with my sister last night
and told her that was something I’d given a great deal of thought. If you feel better, were losing weight, and
you like what you’re eating, even if you never lost another pound—why on earth
would you resume eating foods that you know will make you gain weight and feel
horrible? That’s where I’m at. If not even one more speck of fat leaves my
body, I’ll live with it. I can’t imagine
eating pasta, cakes, and other foods that I know will make me miserable.
Though I don’t need to lose any pounds, I do need to lose
some body fat and develop better musculature.
I know I’ll do it, and by the end of the year, I plan on being extremely
toned. I’ve already started the photo
journal that I will post at the end of the year so that you can see with your
very own eyes how fat can make you less fat.
Ok. So, we've covered
carbs and protein. What about fat? How much and what types? This is the one that freaks most people out,
because I believe that your fat intake should be greater than 65% of your daily
caloric intake. This will increase
depending on your caloric needs, and that varies from individual to
individual. It also varies during
different stages of your life. When you
are less active, you need less energy; and when you are more active you need
more energy. If your protein
requirements stay the same, and your carb requirements stay the same, there’s
only one other source to bump up your calories when your body needs them, and
that is through fat.
The best fats? Saturated and monounsaturated fats.
Saturated fats are solid at room temperature and have been
given a bad rap by many in the scientific/medical community. The truth is, these are very healthy fats provided carbohydrate intake is low. Without saturated fats our bodies can’t
absorb calcium which leads to bone loss and osteoporosis; they actually help to
improve your cholesterol levels by increasing your HDL (good) cholesterol; helps
your immune system due to their anti-fungal, anti-viral, and anti-bacterial
properties; and it provides energy for your brain and nervous system. (Walling, 2010)
Where do we find saturated fats? Palm and coconut oils. Butter.
Dark chocolate. Rendered animal fats (tallow and lard). Fish.
Meat. Cheese. These are all excellent—and delicious—natural
saturated fat sources. I realize that
for every article I cite stating the benefits of saturated fats (or fats in
general), you’ll be able to find 100 more that say NO! To that, all I can say is this: Look at those who eat this way and then make
your decision. The proof is there to
dispute what the so-called experts are saying.
Monounsaturated fats (MUFA’s) are considered good fats by
anyone’s reckoning. They can be found in avocado, seeds, and nuts, to name a
few. A quote from heart.org “Monounsaturated
fats can help reduce bad cholesterol levels in your blood and lower your risk
of heart disease and stroke. They also provide nutrients to help develop
and maintain your body’s cells. Monounsaturated fats are also typically
high in vitamin E, an antioxidant vitamin most Americans need more of.”
There are also polyunsaturated
fats (PUFA’s), and this is where disagreements abound. Some say yes, yes, yes... others say no way,
Jose, and others say, some but not certain ones. Again, I fall into the latter category. Not all PUFAs are bad for you. What I find shocking is that anyone would
call canola oil a good one. I’m sorry,
but it is so over-processed that whatever benefits it may have had isn't worth
it. Add to the over-processing the fact
that they have to deodorize it—well, I want my fat without deodorant.
The worst thing I can say about these types of fats is that
they contain too much Omega-6. Yes, we
are supposed to have Omega-6 in our diet, but not to the extent that we get
it. Ideally, we should have a 1:1 ratio
of Omega6:Omega3, two essential fatty acids (essential because the only way to
get them is to eat them)—but the truth is, we get far more Omega-6 than
Omega-3, which is another cause for so much chronic inflammation, pain, and the
whole litany of health hazards associated with chronic inflammation, that it
would behoove us all to mind ourselves when it comes to the PUFAs.
Ah, I touched on the Omega-6:Omega-3’s in the previous
paragraph. A few more words on that
topic. Again, they are called essential
because you can only get them by ingestion.
So, while the ratio should be 1, it is much higher than that—15:1—in the
average diet. Even us Paleo folks tend
to get too many because we think these PUFAs are good for us, or we overeat
nuts. Whatever the reason, we all need
to drastically reduce the amounts of Omega-6 in our diets. (The Center for Genetics, Nutrition and Health, 2002)
Well, that’s it for our overview of fats, proteins, and
carbohydrates as fuel sources. Next
time, I’ll explain how we can convert our bodies—our high performance machines—into
fat burners, and keep them that way.
Until then...
