Why a calorie is not just a calorie
One misconception about fat loss is the conservative scientific view that "a calorie
is just a calorie" and the only thing that matters is calories in versus calories out. If fat
loss were that simple, then you could eat anything you wanted and you would still lose fat
as long as your calories were below maintenance. For example, you could eat nothing but
Hershey's bars and drink nothing but Coca Cola and if you were 100 calories under
maintenance, you'd lose weight. Common sense alone tells you this isn't true.
If a calorie is just a calorie, then three diets at the same calorie level, the first
composed of 100% protein, the second 100% carbohydrates and the third 100% fats,
would all have the same effect on body composition. Believe me, a diet consisting of
100% tuna fish (lean protein) will not have the same effect as a diet consisting of 100%
potato chips (fat and carbohydrate).
Calorie balance is the most important issue in fat loss but there's more to it than
that. Other variables include the thermic effect of food, the effect of each food on
hormones and blood sugar levels and the macronutrient ratios of each meal.

Calculate your calories first, then split them up into the proper ratios of protein,
carbohydrate and fat
The first step in developing your own custom-tailored fat loss program is to do
your calorie calculations. Only then should you divide up your daily allotment among the
three macronutrients; carbohydrates, proteins and fats. Many authorities suggest
calculating how many grams of protein, carbohydrates and fat you need based on
bodyweight and then the calories will take care of themselves. There's some merit to this
method if the gram recommendations are figured properly for your personal needs, but
the shortcoming of this method is lack of precision; it can only give you a ballpark
estimate.
For example, a common guideline for protein consumption is one gram per pound
of bodyweight. Serious bodybuilders engaged in high-intensity training are often advised
to eat as much as 1.25 to 1.5 grams per pound of bodyweight. One gram per pound is an
excellent general guideline for bodybuilding or fat loss programs. The problem with this
method is the same one we discussed with calorie calculations based only on body weight
– it doesn’t account for training and activity levels. Always calculate your calorie needs
FIRST (based on activity, goals, body weight or lean body mass), then once you’ve
figured out your calorie needs, you can divvy them up like you’d slice up a pie.
Dividing your calories into the right ratios can have a profound impact on your
body composition. As in the tuna fish and potato chip example, two diets of equal
calories can have totally different effects; one 2400-calorie diet can get you ripped and
another 2400-calorie diet can get you fat.
The first rule of macronutrient ratios: Always eat proteins and carbohydrates
together
Before we get into specific ratios and percentages, you must first understand the
most basic rule of nutrient ratios: Your diet should never consist primarily of one food
type or one macronutrient type; there must be a proper balance between proteins,
carbohydrates and fats. Without even doing any sophisticated number crunching, you'll
always be in the ballpark simply by having a serving of lean protein and a serving of
complex carbohydrate at every meal. If you frequently eat carbohydrates or proteins by
themselves, your ratios will be "out of balance" and your results will be compromised.

The myth of "food separating" and why it's not effective for improving body
composition
A common myth in the diet world says that you should never eat certain
carbohydrates and proteins together in the same meal. This diet fad is known as "food
combining" (Actually, it would be more accurately described as "food separating,"
referring to the belief that certain combinations of foods, such as meat and potatoes,
shouldn't be eaten together). Popularized in the 1980's by Judy Mazel's Beverly Hills
Diet, Marilyn and Harvey Diamond's "Fit For Life Diet," and more recently by Don
Lemmon's "Know How" diet, this fad still attracts followers to this day.
Arguments for separating proteins and carbohydrates usually go something like
this: Protein digests in an acidic medium of pepsin (a digestive enzyme) and hydrochloric
acid, while carbohydrates digest in an alkaline medium. Therefore, when protein and
carbohydrates are consumed together, they can’t be fully assimilated, resulting in poor
digestion, incomplete absorption of nutrients and gastrointestinal disturbances. Mazel
went as far as to claim that by eating large quantities of fruit alone, the fruit enzymes
would prevent the calories from being stored as body fat. It’s also been suggested that
poor digestion from improper food combinations will weaken you, sap your energy and
stress your immune system.
These ideas make for excellent book sales, but where this fad diet falls flat on its
face is that it vastly underestimates the power of the human digestive system. There’s no
evidence whatsoever supporting the practice of separating carbohydrate and protein
feedings.
I know several people who say that these programs removed their gastrointestinal
distress and made them “feel” better. However, I don't know a single bodybuilding or
fitness champion who successfully uses "food combining" diets to achieve low body fat
or excellent muscular development (Although there are some who get paid to say they
do). If muscles and low body fat are your goals, then lean proteins and complex
carbohydrates should always be eaten at every meal.
The ultimate meal combination for burning fat and building muscle
On the BFFM program, a meal is not a meal if it doesn't contain a complex
carbohydrate and a lean protein. Occasionally, eating a piece of fruit, a nonfat yogurt, a
cup of cottage cheese, a protein drink, or another carbohydrate or protein all by itself is
fine, but that doesn't count as a full meal, it only counts as a "snack."

The ultimate meal combination for burning fat is a lean protein, a starchy
carbohydrate and a fibrous carbohydrate eaten together at the same meal
Here are three examples of the "Ultimate meal combination"
Example 1:
Brown Rice (complex carb)
Mixed green salad (complex fibrous carb)
Salmon (lean protein)
Example 2:
Sweet potato (complex carb)
Broccoli (complex fibrous carb)
Chicken breast cutlet (lean protein)
Example 3
:
Oatmeal (complex carbohydrate)
Egg white omelet with one yolk (lean protein)
Grapefruit (natural simple carb – optional)
8 reasons why you must eat lean proteins and complex carbohydrates together at
every meal to maximize fat loss and muscle growth.
To gain muscle and lose fat, it's not only unnecessary to separate carbohydrates
and proteins - it's counterproductive. Here are 8 convincing scientific reasons why. Read
them and then you be the judge of whether you want to eat a meal without your protein
and carbohydrates.
1) To maintain positive nitrogen balance, a state where you are retaining more protein
than you excrete, resulting in a net gain of muscle tissue, you must consume protein
approximately every three hours. Proteins cannot be stored like carbohydrates. This
requires protein feedings with every meal. Eat carbohydrates by themselves without
protein, and your body must break down muscle to get the amino acids it needs (You "eat
up" your own muscle tissue!)
2) To get the protein (amino acids) into the muscle cells efficiently requires insulin.
Insulin is secreted most readily in response to eating carbohydrates. Therefore, a
moderate (but not over-sized) portion of carbohydrate should be eaten with your protein
to facilitate the uptake of the amino acids into the muscle cell. The exception to this rule

141
is when you’re on a "contest diet," and carbohydrates are being restricted (More on
carbohydrate restriction in chapter 12).
3) Eating carbohydrates by themselves, especially the simple variety, causes a rapid
increase in blood sugar. Peaks in blood sugar are always followed by valleys in blood
sugar (also known as "hypoglycemia"). Cravings, hunger and fatigue usually follow. If
you get hunger or bad cravings, it could be because you're eating too many simple
carbohydrates by themselves (Fat-free snack foods, etc.).
4) Quick elevations in blood sugar caused by eating carbohydrates by themselves cause a
large release of insulin to remove the excess glucose from the bloodstream. A slow,
moderate output of insulin is desirable; a large release of insulin is not. High
concentrations of insulin in the bloodstream are lipogenic; they promote the storage of
body fat as well as prevent stored body fat from being mobilized. In the long run, this can
also lead to a diabetes-like condition in those genetically prone to it.
5) The body's stores of muscle glycogen are very limited (Between 300 and 400 grams).
Muscle glycogen is the primary source of energy for weight training. If your glycogen
levels become severely depleted, your training will suffer. Advocates of very low
carbohydrate, high protein, high fat diets claim that your body will learn to function on fat
and protein and they make convincing scientific-sounding arguments to back up their
position. However, if you were to ask any champion bodybuilder how a low carbohydrate
diet affects their training, virtually all of them would tell you that it reduces their energy,
lowers their intensity, and makes it difficult to get a pump. Even on carbohydrate-
restricted programs it's important to get some carbohydrates or your workouts will suffer
badly. If you cut out your carbohydrates completely or separate your protein and
carbohydrate feedings in a food-combining diet, your glycogen stores will be
compromised. You need a slow and moderate, but steady flow of complex carbohydrates
throughout the day. Eating too many carbohydrates at once can cause fat storage, so the
ideal way to consume them is in moderate portions at every meal.
6) Protein eaten with every meal slows the digestion of the carbohydrates, resulting in
steadier blood sugar and energy levels and a more moderate output of insulin - without
the ups and downs of eating carbohydrates by themselves.
7) Eating fiber-containing carbohydrates at every meal slows the digestion of the
carbohydrates, resulting in a steadier blood sugar level and more moderate insulin output.

8) Eating protein at every meal enhances the thermic effect, which helps to speed up your
metabolic rate. A meal consisting of only carbohydrate is less thermic than one
containing a lean protein and a complex carbohydrate. A meal or snack that’s high in fat
without protein is the least thermic of all (sugar and fat, i.e., doughnuts, pastries, potato
chips, etc.).
What are "macronutrient ratios?"
We’re now ready to get into the nitty gritty of macronutrient ratios (Also called
"nutrient ratios"). The first thing you should know is that nutrient ratios simply refer to
the percentage of your total daily calories that come from protein, carbohydrate and fat.
For example, 60-30-10 or 40-30-30 are nutrient ratios. A nutrient ratio of 30% protein on
2400 calories per day would be 720 calories of protein (.30% protein X 2400 calories =
720 protein calories).
Developing nutrition plans based on ratios of protein, carbohydrates and fats has
been practiced for decades among bodybuilders. However, it wasn't until 1995 that
nutrient ratios gained widespread attention from the public with the release of a book by
Dr. Barry Sears called "The Zone." This book made “meal ratios” household words
because the entire Zone program is based on the nutrient ratio of 40% carbohydrate, 30%
protein and 30% fat (or "40-30-30"). By following the 40-30-30 ratios, Dr. Sears claimed
you would lose weight, gain muscle, improve athletic performance and cure a whole host
of diseases and health problems.
Two valuable lessons you can learn from the Zone Diet - even though 40-30-30
got thumbs down from most mainstream health and nutrition organizations
Despite its popularity and best-seller status, the Zone Diet has some serious
shortcomings. The biggest flaw of the Zone program as Dr. Sears prescribed it in his 1995
book, is dangerously low calories. The Zone is basically just another very low calorie
diet. That’s why Zone dieters often run into to the same pitfall that every other low
calorie dieter succumbs to - the starvation mode.
Suppose you weigh 175 lbs. and your body fat is 10%. That means you have 17.5
lbs. of fat and your lean body mass (LBM) is 157.5 lbs. If you work out five times per
week for one hour, then according to Dr. Sears, you should consume .8 grams of protein
per lb. of LBM. That's an "activity factor” of .8 X 157.5 (LBM), which equals 126 grams
of protein.
There are four calories in each gram of protein, so that's 504 calories from protein
or 30% of your total calories. Your fats should also be 30% of your total calories. 504 fat

143
calories, divided by nine calories per fat gram equals 56 grams of fat. Your carbohydrates
should be slightly higher, about 40% of your total calories, or 672 carbohydrate calories.
There are four calories in each gram of carbohydrate so that's 168 grams of carbohydrates.
Add up all these calories and you get 1680 calories for the day:
Zone diet recommendations for a 175-pound moderately active man:
Carbs: 672 calories = 168 grams = 40% of total calories
Protein: 504 calories = 126 grams = 30% of total calories
Fat: 504 calories = 56 grams = 30% of total calories
Total: 1680 calories
1680 calories is too low for a moderately active man. The protein
recommendations fall short as well: 126 grams of protein is plenty for a couch potato, but
not enough to support a program with cardio and high intensity weight training. Will you
lose weight on 1680 calories? Sure - but it won't be long before the starvation mode kicks
in.
As a whole, the Zone program was denounced by nearly every mainstream health
and nutrition organization in the world, including the American Dietetic Association, the
Mayo Clinic, the American College of Sports Medicine, the Center for Science in the
Public Interest, and many others. However, you can learn some important things from the
Zone by reading it selectively, plucking out the useful tidbits and throwing away the rest.
The Zone made two particularly important contributions to modern trends in
nutrition that have shifted the predominant thinking about fat loss in the bodybuilding and
weight loss world since 1995.
First, The Zone brought to the public's attention the importance of having a good
balance between proteins, carbohydrates and fats instead of being heavily slanted towards
mostly carbohydrate at the expense of protein and fat - a big mistake in our day and age of
"fat phobia" and “high carbohydrate mania.” It also pointed out the dangers of eating
large amounts of processed carbohydrates such as white breads, white pastas, fat free
snack foods and baked goods.
The second important point made by the Zone program was the idea of always
combining a lean protein and complex carbohydrate food at every meal. This is probably
one of the most important aspects of a nutrition program designed for improving body
composition, because it helps to control the hormones responsible for fat storage and it
provides a steady flow of amino acids from protein foods for muscle growth and
maintenance.

No single ratio is "the best" and no single ratio will work for everyone 100% of the
time
Many dieters are tempted to believe that there is one perfect or "magical" ratio
that will be the answer to all their body fat problems. Contrary to what some "diet gurus"
would like you to believe, there is no single best ratio.
No ratio has any "magical" fat-burning or muscle-building properties. No ratio will override the law of calorie balance. Any impact nutrient ratios have
on your body fat level is minimal compared to the effect that calorie levels have
on body composition. No nutrient ratio will prevent you from going into starvation mode if your calories
are too low. No nutrient ratio will prevent you from accumulating body fat if your calories are
too high. No nutrient ratio will allow you to gain muscle if your calories are too low. No single nutrient ratio will work for everyone. Optimal nutrient ratios depend on
goals and differences in body types and carbohydrate sensitivity.
Calories are always the most important factor in fat loss and the first factor you
should consider. Only then can you accurately calculate the optimal ratios of protein,
carbohydrate and fat specifically for your unique needs.
Any program that suggests only one ratio for everyone is completely ignoring the
concept of nutritional individuality. Clearly, your ratios must be customized, but as you
will learn shortly, there is a sensible place where everyone can start.
Basic definitions of high, low and moderate macronutrient percentages
Drawing a rigid line between ratios is difficult, but for the purposes of our
discussions in the BFFM program, let's clarify what we mean when we're talking about
high, medium and low carbohydrate, macronutrient percentages.
Copyright 2003, Fitness Renaissance, LLC
http://www.fitren.com
145
Carbohydrate definitions:
Very high carb = 65- 70% +
High carb = 55-60%
Moderate carb = 40-50%
Low carb = 25-35%
Very low carb (ketogenic) = about 5-15% or 30-70 grams per day
Protein definitions:
Very high protein = 41-50%+
High protein = 31-40%
Moderate protein = 25-30%
Low protein = 15-24%
Very low protein = less than 15%
Fat definitions:
Very high fat = 40% +
High fat = 30%-39%
Moderate fat = 20-29%
Low fat = 10-19%
Very low fat = less than 10%
With such a wide range in each category, how do you know what percentage is
best? One tip is to avoid the extremes. Extremely low or extremely high ratios of
anything are usually not the best approach. There are exceptions of course: Competitive
bodybuilders sometimes jack up their protein sky-high to as much as 40-50% for short
periods before contests.
Some endurance athletes perform best on very high carbohydrate intakes of 60-
70% of their total calories. Carbohydrate sensitive people sometimes have no choice but
lower carbohydrate intake to 30% or less of their total calories. These cases are the
exceptions rather than the rule, however. Moderate to high complex carbohydrate, with
moderate protein and low fat is generally the best approach. Modifications can then be
made to this baseline as your needs require.
Popular approaches to nutrient ratios
Before we talk about your starting point or "baseline" ratios, let’s take a look at
some of the nutrient ratios that popular diet programs recommend.

High carbohydrate, very low fat
In the 80s and 90s, most diet programs called for very low fat, low protein and
extremely high carbohydrate. The Pritkin diet, which recommended 70% carbohydrate,
20% protein and 10% fat, is one example. Other programs falling into this category are
the Dean Ornish’s "Eat More Weigh Less" program, Robert Hass's "Eat to Win" and
vegetarianism.
If the right types of carbohydrates are eaten, this is probably a healthy way to eat,
but it's so lopsided in favor of carbohydrates, you can't really say it’s "balanced" and this
approach definitely isn't for everyone. When it comes to shifting body composition from
fat to muscle, many people simply don't respond well to high carbohydrates, no matter
how carefully they are chosen. Very high carbohydrate, low fat diets are also a bit light on
essential fats, and the protein levels are too low to support serious weight training. Some
extremely carbohydrate-sensitive people actually see increases in cholesterol and
triglycerides when their carbs are too high.
Very low carbohydrate /high fat, high protein
On the other end of the spectrum you have the very high fat, high protein, very
low carbohydrate diets. The Atkin's Diet is the most popular. Others include Protein
Power, The Carbohydrate Addicts Diet, Sugar Busters, The Ketogenic diet, The Anabolic
Diet and a whole host of other programs that impose strict regulations on the amount of
carbohydrate you can eat.
The basic assumption of the very low carbohydrate approach is that carbohydrates
cause fat storage because they increase insulin production. Insulin is portrayed as an evil
fat-storing monster that makes everything you eat turn into fat. The objective of these
programs is to control insulin by cutting out carbohydrates and this will supposedly cause
rapid body fat loss.
There is some truth in these arguments, but unfortunately, the information has
been distorted and taken to extremes. Contrary to what certain diet "gurus" tell you,
carbohydrates are not fattening. What's fattening is eating more calories than your body
can use at one time. Insulin can be a double-edged sword, but insulin control can be easily
achieved without extreme measures.
It's true that some people lose weight more quickly on a very low carbohydrate
diet, but that's not the same thing as saying carbohydrates are fattening. It's also true that
Copyright 2003, Fitness Renaissance, LLC
http://www.fitren.com
147
almost every bodybuilder or fitness competitor uses some variation of the low
carbohydrate diet to prepare for competitions.
Very low carbohydrate diets work almost all of the time for all body types. The
problem is they also fail to keep body fat off permanently almost all of the time. It's
nearly impossible to stay on low carbohydrates for a long time (nor can I figure out why
you would want to). It’s also up for debate whether the very high saturated fat levels
allowed in these programs are healthy or not.
Most people will lose fat simply by adding a regular exercise routine to their
schedule and by "cleaning up" their diets. A “clean" diet means you’ve mastered all the
nutritional basics like eating small frequent meals, controlling portion sizes, cutting down
on saturated fats, avoiding sugar, drinking plenty of water and eating lean protein at every
meal.
Moderate carbohydrate restriction will usually speed up fat loss, but a very low
carbohydrate diet is not the ultimate answer to permanent fat loss. At worst it’s unhealthy
and causes muscle loss. At best it’s a temporary tool that should only be used for short
periods for specific fat loss goals (such as preparing for bodybuilding competition).
The flaw in the very low carbohydrate approach is the assumption that everyone is
carbohydrate sensitive. According to my research, I estimate that only 20% - 30% of the
population is carbohydrate sensitive and only a fraction of that 20%-30% is seriously
carbohydrate sensitive. The best way to look at very low carbohydrate /high fat/high
protein diets is as a last resort for those with extreme difficulty losing fat the conventional
way.
