Such a theory could potentially
unlock all the secrets of nature and the universe
itself, or as theoretical physicist Michio Katu, puts
it "an equation an inch long that would allow
us to read the mind of God." That's how important
unified theories can be. However, unified theories
don't have to deal with such heady topics as physics
or the nature of the universe itself, but can be applied
to far more mundane topics, in this case nutrition.
Regardless of the topic, a unified
theory, as sated above, seeks to explain seemingly
incompatible aspects of various theories. In this
article I attempt to unify seemingly incompatible
or opposing views regarding nutrition, namely, what
is probably the longest running debate in the nutritional
sciences: calories vs. macro nutrients.
One school, I would say the 'old
school' of nutrition, maintains weight loss or weight
gain is all about calories, and "a calorie is
a calorie," no matter the source (e.g., carbs,
fats, or proteins). They base their position on various
lines of evidence to come to that conclusion.
The other school, I would call more
the 'new school' of thought on the issue, would state
that gaining or losing weight is really about where
the calories come from (e.g., carbs, fats, and proteins),
and that dictates weight loss or weight gain. Meaning,
they feel, the "calorie is a calorie" mantra
of the old school is wrong. They too come to this
conclusion using various lines of evidence.
This has been an ongoing debate
between people in the field of nutrition, biology,
physiology, and many other disciplines, for decades.
The result of which has led to conflicting advice
and a great deal of confusion by the general public,
not to mention many medical professionals and other
groups.
Before I go any further, two key
points that are essential to understand about any
unified theory:
A good unified theory is simple,
concise, and understandable even to lay people. However,
underneath, or behind that theory, is often a great
deal of information that can take up many volumes
of books. So, for me to outline all the information
I have used to come to these conclusions, would take
a large book, if not several and is far beyond the
scope of this article.
A unified theory is often proposed by some theorist
before it can even be proven or fully supported by
physical evidence. Over time, different lines of evidence,
whether it be mathematical, physical, etc., supports
the theory and thus solidifies that theory as being
correct, or continued lines of evidence shows the
theory needs to be revised or is simply incorrect.
I feel there is now more than enough evidence at this
point to give a unified theory of nutrition and continuing
lines of evidence will continue (with some possible
revisions) to solidify the theory as fact.
"A calorie is a calorie"
The old school of nutrition, which
often includes most nutritionists, is a calorie is
a calorie when it comes to gaining or losing weight.
That weight loss or weight gain is strictly a matter
of "calories in, calories out." Translated,
if you "burn" more calories than you take
in, you will lose weight regardless of the calorie
source and if you eat more calories than you burn
off each day, you will gain weight, regardless of
the calorie source.
This long held and accepted view
of nutrition is based on the fact that protein and
carbs contain approx 4 calories per gram and fat approximately
9 calories per gram and the source of those calories
matters not. They base this on the many studies that
finds if one reduces calories by X number each day,
weight loss is the result and so it goes if you add
X number of calories above what you use each day for
gaining weight.
However, the "calories in calories
out" mantra fails to take into account modern
research that finds that fats, carbs, and proteins
have very different effects on the metabolism via
countless pathways, such as their effects on hormones
(e.g., insulin, leptin, glucagon, etc), effects on
hunger and appetite, thermic effects (heat production),
effects on uncoupling proteins (UCPs), and 1000 other
effects that could be mentioned.
Even worse, this school of thought
fails to take into account the fact that even within
a macro nutrient, they too can have different effects
on metabolism. This school of thought ignores the
ever mounting volume of studies that have found diets
with different macro nutrient ratios with identical
calorie intakes have different effects on body composition,
cholesterol levels, oxidative stress, etc.
Translated, not only is the mantra
"a calorie us a calorie" proven to be false,
"all fats are created equal" or "protein
is protein" is also incorrect. For example, we
no know different fats (e.g. fish oils vs. saturated
fats) have vastly different effects on metabolism
and health in general, as we now know different carbohydrates
have their own effects (e.g. high GI vs. low GI),
as we know different proteins can have unique effects.
The "calories don't matter"
school of thought
This school of thought will typically
tell you that if you eat large amounts of some particular
macro nutrient in their magic ratios, calories don't
matter. For example, followers of ketogenic style
diets that consist of high fat intakes and very low
carbohydrate intakes (i.e., Atkins, etc.) often maintain
calories don't matter in such a diet.
Others maintain if you eat very
high protein intakes with very low fat and carbohydrate
intakes, calories don't matter. Like the old school,
this school fails to take into account the effects
such diets have on various pathways and ignore the
simple realities of human physiology, not to mention
the laws of thermodynamics!
The reality is, although it's clear
different macro nutrients in different amounts and
ratios have different effects on weight loss, fat
loss, and other metabolic effects, calories do matter.
They always have and they always will. The data, and
real world experience of millions of dieters, is quite
clear on that reality.
The truth behind such diets is that
they are often quite good at suppressing appetite
and thus the person simply ends up eating fewer calories
and losing weight. Also, the weight loss from such
diets is often from water vs. fat, at least in the
first few weeks. That's not to say people can't experience
meaningful weight loss with some of these diets, but
the effect comes from a reduction in calories vs.
any magical effects often claimed by proponents of
such diets.
Weight loss vs. fat loss!
This is where we get into the crux
of the true debate and why the two schools of thought
are not actually as far apart from one another as
they appear to the untrained eye. What has become
abundantly clear from the studies performed and real
world evidence is that to lose weight we need to use
more calories than we take in (via reducing calorie
intake and or increasing exercise), but we know different
diets have different effects on the metabolism, appetite,
body composition, and other physiological variables...
Brink's Unified Theory of Nutrition
...Thus, this reality has led me
to Brink's Unified Theory of Nutrition which states:
"Total calories dictates how
much weight a person gains or loses;
macro nutrient ratios dictates what a person gains
or loses"
This seemingly simple statement
allows people to understand the differences between
the two schools of thought. For example, studies often
find that two groups of people put on the same calorie
intakes but very different ratios of carbs, fats,
and proteins will lose different amounts of bodyfat
and or lean body mass (i.e., muscle, bone, etc.).
Some studies find for example people
on a higher protein lower carb diet lose approximately
the same amount of weight as another group on a high
carb lower protein diet, but the group on the higher
protein diet lost more actual fat and less lean body
mass (muscle). Or, some studies using the same calorie
intakes but different macro nutrient intakes often
find the higher protein diet may lose less actual
weight than the higher carb lower protein diets, but
the actual fat loss is higher in the higher protein
low carb diets. This effect has also been seen in
some studies that compared high fat/low carb vs. high
carb/low fat diets. The effect is usually amplified
if exercise is involved as one might expect.
Of course these effects are not
found universally in all studies that examine the
issue, but the bulk of the data is clear: diets containing
different macro nutrient ratios do have different
effects on human physiology even when calorie intakes
are identical (1,2,3,4,5,6,7,8,9,10,11).
Or, as the authors of one recent
study that looked at the issue concluded:
"Diets with identical energy
contents can have different effects on leptin concentrations,
energy expenditure, voluntary food intake, and nitrogen
balance, suggesting that the physiologic adaptations
to energy restriction can be modified by dietary composition."(12)
The point being, there are many
studies confirming that the actual ratio of carbs,
fats, and proteins in a given diet can effect what
is actually lost (i.e., fat, muscle, bone, and water)
and that total calories has the greatest effect on
how much total weight is lost. Are you starting to
see how my unified theory of nutrition combines the
"calorie is a calorie" school with the "calories
don't matter" school to help people make decisions
about nutrition?
Knowing this, it becomes much easier
for people to understand the seemingly conflicting
diet and nutrition advice out there (of course this
does not account for the down right unscientific and
dangerous nutrition advice people are subjected to
via bad books, TV, the 'net, and well meaning friends,
but that's another article altogether).
Knowing the above information and
keeping the Unified Theory of Nutrition in mind, leads
us to some important and potentially useful conclusions:
An optimal diet designed to make
a person lose fat and retain as much LBM as possible
is not the same as a diet simply designed to lose
weight.
A nutrition program designed to create fat loss is
not simply a reduced calorie version of a nutrition
program designed to gain weight, and visa versa.
Diets need to be designed with fat loss, NOT just
weight loss, as the goal, but total calories can't
be ignored.
This is why the diets I design for people-or write
about-for gaining or losing weight are not simply
higher or lower calorie versions of the same diet.
In short: diets plans I design for gaining LBM start
with total calories and build macro nutrient ratios
into the number of calories required. However, diets
designed for fat loss (vs. weight loss!) start with
the correct macro nutrient ratios that depend on variables
such as amount of LBM the person carries vs. bodyfat
percent , activity levels, etc., and figure out calories
based on the proper macro nutrient ratios to achieve
fat loss with a minimum loss of LBM. The actual ratio
of macro nutrients can be quite different for both
diets and even for individuals.
Diets that give the same macro nutrient ratio to all
people (e.g., 40/30/30, or 70,30,10, etc.) regardless
of total calories, goals, activity levels, etc., will
always be less than optimal. Optimal macro nutrient
ratios can change with total calories and other variables.
Perhaps most important, the unified theory explains
why the focus on weight loss vs. fat loss by the vast
majority of people, including most medical professionals,
and the media, will always fail in the long run to
deliver the results people want.
Finally, the Universal Theory makes it clear that
the optimal diet for losing fat, or gaining muscle,
or what ever the goal, must account not only for total
calories, but macro nutrient ratios that optimize
metabolic effects and answer the questions: what effects
will this diet have on appetite? What effects will
this diet have on metabolic rate? What effects will
this diet have on my lean body mass (LBM)? What effects
will this diet have on hormones; both hormones that
may improve or impede my goals? What effects will
this diet have on (fill in the blank)?
Simply asking, "how much weight
will I lose?" is the wrong question which will
lead to the wrong answer. To get the optimal effects
from your next diet, whether looking to gain weight
or lose it, you must ask the right questions to get
meaningful answers.
Asking the right questions will
also help you avoid the pitfalls of unscientific poorly
thought out diets which make promises they can't keep
and go against what we know about human physiology
and the very laws of physics!
People that want to know my thoughts
on the correct way to lose fat should read my ebook
Diet Supplements Revealed, see this website Diet
Supplements Revealed
If you want to know my thoughts
on the best way to set up a diet to gain weight in
the form of muscle while minimizing bodyfat, consider
reading my ebook Muscle Building Nutrition (AKA Brink's
Bodybuilding Bible) at this web site: Muscle
Building Nutrition
BTW, both ebooks also cover supplements
for their respective goals along with exercise advice.
There are of course many additional
questions that can be asked and points that can be
raised as it applies to the above, but those are some
of the key issues that come to mind. Bottom line here
is, if the diet you are following to either gain or
loss weight does not address those issues and or questions,
then you can count on being among the millions of
disappointed people who don't receive the optimal
results they had hoped for and have made yet another
nutrition "guru" laugh all the way to the
bank at your expense.
Any diet that claims calories don't
matter, forget it. Any diet that tells you they have
a magic ratio of foods, ignore it. Any diet that tells
you any one food source is evil, it's a scam. Any
diet that tells you it will work for all people all
the time no matter the circumstances, throw it out
or give it to someone you don't like!
