Aerobic
Exercise is
any continuous activity of large muscle groups that forces your heart and
lungs to work harder for an extended period of time. Aerobic means
"requiring oxygen". Examples include walking, swimming, stair
climbing, and bike riding.
ADP—Adenosine
di-phosphate, a high energy phosphate molecule involved in the production
and storage of energy. The end product of the mono-phosphate reduction of
ATP.
Adequate Intake is the intake level that sustains a defined
nutritional status, such as growth rate, normal circulating nutrient
values, or other functional indicators of health.
Adipex - A Brand Name for Phentermine, an
appetite suppressant used to reduce calorie intake
Adipocytes - The scientific term for Fat
Cells, being various types of specialized cells found in adipose tissue
used for fat storage. One could perhaps say this it is a rather obese term
for Fat Cells.
Adipose tissue - A specialized type of
tissue for storing cellular fat.
Aerobic—With, or in the presence of,
oxygen; Aerobic metabolism most efficiently produces the basic energy
source, adenosine triphosphate (ATP). Walking, jogging, biking, an aerobic
exercise class and any activity which maintains the heart rate in the THR
zone for a minimum of 20 minutes is aerobic activity. Tennis and
basketball are not considered aerobic activities
Aerobic
Exercise—Aerobic exercise refers sustained exercise that uses large
muscle groups and places demands on the cardiovascular system
Allergy
is an exaggerated response by the immune system in susceptible
individuals. Signs of allergic reactions include sneezing, coughing,
nausea, vomiting, diarrhea, and rashes.
Anaerobic Exercise requires your body to perform at explosive
bursts for a relatively short duration. In this type of exercise, your
body relies heavily on stored energy that does not need oxygen to be
released. Examples include weightlifting and sprinting.
Anaerobic Threshold—The point during high intensity
activity when the body can no longer meet its demand for oxygen and
anaerobic metabolism predominates; also called lactate threshold.
Antioxidants, like beta carotene and vitamins C and E, protect the
cells in your body from an unstable form of oxygen called a free radical.
The antioxidant combines with the free radical to prevent it from
attaching to and damaging the cells in your body.
Amino
acids - The essential building blocks of Proteins, nine of which
cannot be manufactured by the body and therefore have to be obtained
through food intake.
Anorectic drugs - Pharmaceutical drugs designed as appetite
suppressants to reduce calorie intake.
Anorexia Nervosa - A psychophysiological
disorder characterized by an abnormal fear of becoming obese and therefor
a distorted self-image. This results in an unwillingness to eat leading to
severe weight loss. It can also be accompanied by vomiting, excessive
exercise and other physiological changes.
Arachidonic Acid: An essential fatty acid that
is the immediate precursor to "bad" eicosanoids found in fatty
red meats, egg yokes, and organ meats.
Artificial
Sweetners
are substances that impart sweetness to foods but supply little or no
energy to the body. They include acesulfame, aspartame, saccharin, and
sucralose.
ATP (Adenosine Triphosphate), a compound that is the main fuel
cells use to synthesize molecules, contract muscles, and various other
tasks.

Bariatric - The branch of medicine dealing with the causes,
prevention, and treatment of obesity, both pharmacological and surgical.
Bariatric
surgery (bear-ee-AT-ric) Surgery on the stomach and/or
intestines to help the patient with extreme obesity lose weight. Bariatric
surgery is a weight-loss method used for people who have a body mass index
(BMI) above 40. Surgery may also be an option for people with a BMI
between 35 and 40 who have health problems like heart disease or type 2
diabetes.
Basal
Metabolic Rate (BMR)
is the rate at which energy is used by the body to maintain basal
metabolism when a person is awake but inactive and has fasted for 14 to 18
hours. The BMR typically accounts for 60 to 70 percent of daily energy
use, but its value depends on body weight and other factors.
Beta
Oxidation—Process by which fat is broken down in order to generate
ATP.
Beta-Oxidation—The process by which fats, in
the form of Acyl-CoA molecules, are broken down in the mitochondria to
generate Acetyl-CoA, the entry molecule for Kreb’s Cycle.
Binge
Eating Disorder - An eating disorder involving uncontrolled eating of
large amounts of food but without vomiting or laxative purging
Bioelectrical impedance analysis (BIA) (im-PEE-dance)
A way to estimate the amount of body weight that is fat and nonfat.
Nonfat weight comes from bone, muscle, body water, organs, and other body
tissues. BIA works by measuring how difficult it is for a harmless
electrical current to move through the body. The more fat a person has,
the harder it is for electricity to flow through the body. The less fat a
person has, the easier it is for electricity to flow through the body. By
measuring the flow of electricity, one can estimate body fat percent.
Biological Value (BV) is a measure of the extent to which protein
in a food can be incorporated into body proteins. It is expressed as the
percentage of the absorbed dietary nitrogen that is retained by the body.
The BV is related to the amino acid composition of a food protein, in
particular whether it contains adequate amounts of all the essential amino
acids.
Blood
Glucose—Blood glucose (blood sugar) refers to sugar in the form of
glucose. The blood sugar level in humans is normally 60 to 100 milligrams
per 100 milliliters of blood; it rises after a meal to as much as 150
milligrams per 100 milliliter of blood, but this may vary.
Body Mass - a measurement of the mass of a body, usually
human, expressed in kilograms (kg) or pounds (lb).
Body
Mass Index (BMI) is
a measure which takes into account a person’s weight and height to gauge
a degree of obesity in adults. BMI results should be interpreted with
caution however, since people with extensive muscle mass - athletes and
body builders, for example and also pregnant women, have increased BMIs
that do not necessarily dictate increase health risks.
Body
Weight - a more common term for Body Mass.
Bontril SR - An appetite suppressant that works by stimulating
the nervous system.
Bulimia Nervosa - An eating disorder involving
episodic binge eating followed by feelings of guilt, depression, and
self-condemnation. It also often involves measures to prevent weight gain,
such as self-induced vomiting, excessive laxatives, dieting, or fasting.

Calorie is the amount of energy needed to raise one liter of water
by one degree Celsius. In practical terms, a calorie is the unit we use to
measure the amount of energy supplied by food and the amount burned by
activity.
Calorie Balance is the difference between how many calories you eat
(calorie intake) and how many you burn (calorie expenditure). When the
calories you eat equal the calories you burn, you maintain your weight.
Eating more calories than you burn results in weight gain. Burning more
calories than you eat results in weight loss.
Calorie Expenditure is the amount of energy your body uses to walk,
run, sleep, read, breathe, or anything else.
Calorie Restriction: The reduction of calories that
maintains adequate levels of proteins and essential fats while supplying
adequate amounts of micronutrients (vitamins and minerals).
Cancer is a mass of cells or group of dispersed cells that exhibit
uncontrolled growth and ability to spread to other tissues; also, any of a
large group of diseases in which cancerous cells are present.
Carbohydrates - A group of organic compounds, including
sugars, starches and fiber, that is a major source of energy for animals.
Carcinogen refers to any substance that has the potential of
causing cancer when cells or organisms are exposed to it. Many act by
altering the genetic material (DNA); these are called genotoxic
carcinogens.
Cardiovascular—Referring to the heart (cardio), blood, and
blood vessels (vascular).
Cardiovascular
Disease is a
general term for all disorders affecting the heart and blood vessels.
Casein is the principal protein in cow's milk, which forms curds
when exposed to acid.
Cellulite - The dimples and bumps in the skin, usually around
the thighs and buttocks, caused when the natural structure of the skin is
stretched by Fat cells growing too large.
Cholesterol—A type of lipid (fatty
substance) that builds inside tissues; The body produces cholesterol, or
it is obtained form eating animal products. The total cholesterol is not
as important as the ratio of low-density lipoproteins, LDLs to
high-density lipoproteins, HDLs. The recommended ratio is below 5 to 1.
Cholesterol accumulation in the arteries due to excess saturated fats in
the diet and lack of exercise leads to atherosclerosis.
Compulsive Overeating - Also known as
Binge Eating.
Cosmeceuticals: Skin care products that
contain vital nutrients, which combat the damage of free radicals and
reduce inflammation, keeping skin in a youthful condition.
Crunch(-es)—Abdominal exercise used to
isolate the abdominals while, at the same time, eliminates unwanted action
from the iliopsoas muscles (hip flexors) and reduces the risk of stress on
the lower back; preferred method of abdominal training over sit-ups.

Diabetes Mellitus (dye-uh-BEE-teez)
A disease that occurs when the body is not able to use blood glucose
(sugar). Blood sugar levels are controlled by insulin, a hormone in the
body that helps move glucose (sugar) from the blood to muscles and other
tissues. Diabetes occurs when the pancreas does not make enough insulin or
the body does not respond to the insulin that is made. There are two main
types of diabetes mellitus: type 1 diabetes and type 2 diabetes
Diet - A change in behavior, food
intake, exercise, or a combination of them which result in a change in
habits with the goal of making one's body more healthy.
Dehydration is the condition that occurs from a loss in body water.
Symptoms of dehydration vary depending on the extent of decreased body
fluid. Thirst, the mildest symptom, can progress and turn into weakness,
dizziness, exhaustion, and in severe cases can eventually lead to death.
Didrex - An appetite suppressant that works by stimulating
the nervous system.
Diet - The food and drink a person or animal consumes in their
normal life, and a regulated eating plan for medical reasons or as a
measure to promote weight loss.
Diuretics - A drug that increases the
discharge of urine, used to move fluid through the body quickly as a form
of purging..

diet because it cannot be produced in sufficient quantities by the body.
Exertional Headaches—Pain triggered by a
variety of exercise activities ranging from weightlifting to jogging, and
including sexual intercourse.

those that are stored in the body fat, principally in the liver: vitamins
A, D, E and K.
Fastin - A brand name for Phentermine previously manufactured by
Smith Kline Beecham but no longer available.
Fat: Compounds composed of hydrogen, carbon, and oxygen atoms
that serve as stored fuel for the body. There are different kinds of fats,
some of which are healthier than others:
- Saturated Fats: unhealthy fats found in most animal products and
tropical oils. With a high proportion of hydrogen atoms, they are solid at
room temperature and are converted to cholesterol in the body.
- Mono-Unsaturated Fat: the healthiest fats, are produced by
plants. With a lower amount of hydrogen atoms, they tend to be liquid at
room temperature.
- Poly-Unsaturated Fats: have the lowest amount of hydrogen atoms,
come from plant sources, and are liquid at room temperature.
- Hydrogenated Fats: found in processed foods and commercially
baked goods, have an extra hydrogen atom added to them to make them solid
at room temperature and to increase the shelf life of foods they are in.
They are considered to be the most unhealthy.
FDA - The Food & Drug Administration is
the US Federal agency responsible for the regulation of biotechnology food
products.
Fiber—Dietary fiber generally refers
to parts of fruits, vegetables, grains, nuts and legumes that can't be
digested by humans.
Free Radicals: Are highly reactive,
imbalanced molecules that are the byproducts of normal metabolism and are
associated with the degenerative aging process. Free radicals steal
electrons from healthy cells to neutralize their own charge, causing
cellular damage. Free radicals are also produced by exposure to cigarette
smoke, smog and other environmental pollutants, harmful chemicals, toxins,
and even sunlight. Antioxidant supplementation will help counter the
effects of free radicals.

it to be manufactured by any company. Phentermine is an example of a
Generic Drug.
Gestational diabetes (jest-AY-shun-ul)
(dye-ah-BEE-teez) A type of diabetes mellitus that can occur when a
woman is pregnant. In the second half of her pregnancy, a woman may have
glucose (sugar) in her blood at a higher than normal level. In about 95
percent of cases, blood sugar returns to normal after the pregnancy is
over. Women who develop gestational diabetes, however, are at risk for
developing type 2 diabetes later in life
Gram
is the basic
unit of mass in the metric system. One gram equals 1/28 of an ounce (0.035
ounces).
Glucose—Simple sugar; the form in which all carbohydrates
are used as the body's principal energy source; transported in the blood
and metabolized in the tissues
Glucagon: The hormone from the pancreas
that causes the release of stored carbohydrate in the liver to restore
blood glucose levels. Glucagon is a mobilization hormone.
Glycemic Index: A measure of the rate at which a
carbohydrate will enter the bloodstream as glucose. Some simple sugars,
such as table sugar, will enter the bloodstream slower than many complex
carbohydrates, such as bread, rice, and potatoes. The faster a
carbohydrate enters the bloodstream, the higher its glycemic index. The
higher the glycemic index of a carbohydrate, the greater the increase in
insulin levels. Fruits and vegetables tend to have a low-glycemic index,
whereas breads, pasta, grains, and starches tend to have a high-glycemic
index.
Glycemic
Load: Is a measure of the density and digestion speed of carbohydrates
(the glycemic index of a food multiplied by the amount of carbohydrates
per serving). The goal of Zone eating is to keep the glycemic load low.
Carrots, for example, even though they have a high glycemic index, have a
much lower glycemic load than pasta because they are less
carbohydrate-dense.
Glycogen
is the
principle storage form of carbohydrate energy (glucose) which is reserved
in muscles and in the liver. Muscles appear fuller when glycogen levels
are high.

freedom from disease or abnormality
Healthy weight Compared to
overweight or obese, a body weight that is less likely to be linked with
any weight-related health problems such as type 2 diabetes, heart disease,
high blood pressure, high blood cholesterol, or others. A body mass index
(BMI) of 18.5 up to 25 refers to a healthy weight, though not all
individuals with a BMI in this range may be at a healthy level of body
fat; they may have more body fat tissue and less muscle. A BMI of 25 up to
30 refers to overweight and a BMI of 30 or higher refers to obese.
High blood pressure Another
word for “hypertension.” Blood pressure rises and falls throughout the
day. An optimal blood pressure is less than 120/80 mmHg. When blood
pressure stays high, greater than or equal to 140/90 mmHg, then it is
considered high blood pressure. High blood pressure increases the risk for
heart disease and stroke.
High-density lipoprotein (HDL) (lip-o-PRO-teen)
A form of cholesterol that circulates in the blood. Commonly called
“good” cholesterol. High HDL lowers the risk of heart disease. An HDL
of 60 mg/dl or greater is considered high and is protective against heart
disease. An HDL less than 40 mg/dl is considered low and increases the
risk for developing heart disease.
High-glycemic: A food is considered to
be high-glycemic if it is broken down rapidly and enters the bloodstream
quickly as glucose.
Homeostasis
refers to the maintenance of consistent internal body conditions. It
is achieved by a series of negative-feedback control mechanisms. For
example, when sensors detect overheating of the body, sweating is
stimulated until the body temperature returns to normal.
Hormones:
Biological compounds that communicate information throughout the body
Hydration refers to the amount of fluid in your body. It is
important to drink at least 64oz. of water throughout the day. More may be
required to replace any fluid your body loses during physical activity.
Hydrogenation
(high-dro-jen-AY-shun) A chemical way to turn liquid fat
(oil) into solid fat. This process creates a new fat called trans fatty
acids. Trans fatty acids are found in margarine, shortening, and some
commercial baked foods like cookies, crackers, muffins, and cereals.
Eating a large amount of trans fatty acids may raise heart disease risk.

Insulin (IN-sah-lin) A
hormone in the body that helps move glucose (sugar) from the blood to
muscles and other tissues. Insulin controls blood sugar levels.
Insulin Resistance: A condition in which
cells no longer respond well to insulin. As a result, the body secretes
more insulin into the bloodstream in an effort to reduce blood glucose
levels.
Intensity refers to how hard your body works during an activity. In
general, the higher your heart rate (that is, the faster your heart beats)
the more intense the activity.

Lipoprotein
(lip-o-PRO-teen) Compounds of protein that carry fats
and fat-like substances, such as cholesterol, in the blood.
Liter (L) is the basic unit of volume in the metric system. One
liter equals 0.95 quarts.
Low-density
lipoprotein (LDL) (lip-o-PRO-teen) A form of cholesterol
that circulates in the blood. Commonly called “bad” cholesterol. High
LDL increases the risk of heart disease. An LDL less than 100 mg/dl is
considered optimal, 100-129 mg/dl is considered near or above optimal,
130-159 mg/dl is considered borderline high, 160-189 mg/dl is considered
high, and 190 mg/dl or greater is considered very high.
Low-glycemic: Low glycemic foods are
broken down into glucose less quickly than high-glycemic foods and enter
the bloodstream at a much slower rate
M
Back

Macronutrients: Foods that contain calories and can therefore
generate hormonal responses. Proteins, fats, and carbohydrates are
macronutrients.
Micronutrients: Vitamins and minerals that
have no caloric value and little direct impact on hormonal response, but
are a vital means of achieving optimal health.
Maximal Oxygen Uptake or VO2 max is the maximum volume of oxygen an
individual can consume per minute of work. It is often used to evaluate an
athlete's cardiovascular efficiency. Trained individuals have a higher VO2
max than untrained individuals allowing for increase intensity and
performance when exercising.
Maximum Heart Rate (MHR) is the fastest that your heart can beat
when doing activity. Rather than actually measuring the peak rate that
your heart can beat, it is easier to predict what that rate is. We can do
this by using a simple formula: 220 – age = maximum heart rate.
Meridia
(sibutramine) - A weight loss diet pill that suppresses appetite by
inhibiting the re-uptake of applicable hormones.
Metabolism - The chemical processes that take
place within a living cell or organism that break down substances to
provide energy and/or raw materials which are then re-synthesized into new
and necessary substances to support life
Monounsaturated fat (mono-un-SATCH-er-ay-ted)
Fats that are in foods are combinations of monounsaturated,
polyunsaturated, and saturated fatty acids. Monounsaturated fat is found
in canola oil, olives and olive oil, nuts, seeds, and avocados. Eating
food that has more monounsaturated fat instead of saturated fat may help
lower cholesterol and reduce heart disease risk. However, it has the same
number of calories as other types of fat, and may still contribute to
weight gain if eaten in excess.

that disrupts the transmission of signals from the neurotransmitters and
is used in the management of obesity.
Physical activity Any form of
exercise or movement. Physical activity may include planned activity such
as walking, running, basketball, or other sports. Physical activity may
also include other daily activities such as household chores, yard work,
walking the dog, etc. It is recommended that adults get at least 30
minutes and children get at least 60 minutes of moderate physical activity
most days of the week. Moderate physical activity is any activity that
requires about as much energy as walking two miles in 30 minutes
Polyunsaturated fat (poly-un-SATCH-er-ay-ted)
A highly unsaturated fat that is liquid at room temperature. Fats
that are in foods are combinations of monounsaturated, polyunsaturated,
and saturated fatty acids. Polyunsaturated fats are found in greatest
amounts in corn, soybean, and safflower oils, and many types of nuts. They
have the same number of calories as other types of fat, and may still
contribute to weight gain if eaten in excess.
Post Exercise
Energy Consumption refers to the continued elevated (above resting) amounts of
calories being burned due to recovery from exercise. During recovery,
calories are burned during muscle and tissue repair and oxygen replacement
in muscles.
Proteins - A group of complex organic

Rating of Perceived Exertion (RPE) is the level of effort you feel
you are putting into an activity. The Borg scale is a rating scale that
helps you describe how hard you feel you are working in terms of a number
from 6 to 20. Lower numbers on the scale are used to describe a lower
level of effort, and higher numbers mean you are working harder.
Registered Dietitian (R.D.) A health professional

Saturated fat (SATCH-er-ay-ted) A fat that is
solid at room temperature. Fats that are in foods are combinations of
monounsaturated, polyunsaturated, and saturated fatty acids. Saturated fat
is found in high-fat dairy products (like cheese, whole milk, cream,
butter, and regular ice cream), fatty fresh and processed meats, the skin
and fat of chicken and turkey, lard, palm oil, and coconut oil. They have
the same number of calories as other types of fat, and may contribute to
weight gain if eaten in excess. Eating a diet high in saturated fat also
raises blood cholesterol and risk of heart disease
Simple Sugars - Single Molecule sugars such as
glucose, fructose, and galactose
Spot
Reduction means
removal of stored fat from specific areas in the body. No activity or
exercise can remove fat from a specific area.
Strength (Resistance or Weight) Training refers to activities

the central nervous system, increasing heart rate and blood pressure and
decreasing your appetite.
Trans fatty acids A fat that
is produced when liquid fat (oil) is turned into solid fat through a
chemical process called hydrogenation (See definition). Eating a large
amount of trans fatty acids also raises blood cholesterol and risk of
heart disease.
Type 1 diabetes (dye-uh-BEET-eez)
Previously known as “insulin-dependent diabetes mellitus,” (IDDM)
or “juvenile diabetes.” Type 1 diabetes is a life-long condition in
which the pancreas stops making insulin. Without insulin, the body is not
able to use glucose (blood sugar) for energy. To treat the disease, a
person must inject insulin, follow a diet plan, exercise daily, and test
blood sugar several times a day. Type 1 diabetes usually begins before the
age of 30.
Type 2 diabetes (dye-uh-BEET-eez)
Previously known as “noninsulin-dependent diabetes mellitus” (NIDDM)
or “adult-onset diabetes.” Type 2 diabetes is the most common form of
diabetes mellitus. About 90 to 95 percent of people who have diabetes have
type 2 diabetes. People with type 2 diabetes produce insulin, but either
do not make enough insulin or their bodies do not use the insulin they
make. Most of the people who have this type of diabetes are overweight.
Therefore, people with type 2 diabetes may be able to control their
condition by losing weight through diet and exercise. They may also need
to inject insulin or take medicine along with continuing to follow a
healthy program of diet and exercise. Although type 2 diabetes commonly
occurs in adults, an increasing number of children and adolescents who are
overweight are also developing type 2 diabetes.
