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.

B

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.

D

 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..

 Duration—Length of time one works or exercises; Duration is one way of increasing resistance to a muscle or system to improve its function.

E

Eicosanoid: An autocrine hormone made by virtually every cell in the body. "Good" eicosanoids are anti-inflammatory, whereas "bad" eicosanoids cause inflammation.

EPA (Eicosapentaenoic Acid): An omega-3 fatty acid found in cold-water fish and fish-oil; a precursor to "good" eicosanoids.

Essential Fatty Acid— Fatty acid that can not be generated by other fatty acids in the body. The essential fatty acids include linoleic, linolenic, and arachadonic acids.

Empty Calories—Calories obtained from foods high in sugar and fat without significant nutritional value (vitamins and minerals).

Energy expenditure The amount of energy, measured in calories, that a person uses. Calories are used by people to breath, circulate blood, digest food, and be physically active.

Essential Nutrient—A nutrient that must be supplied by the 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.

 Exercise - A physical or mental activity used as a method of maintaining or improving a level of fitness. An important part of an overall weight loss plan of action.

 Fad Diets - Fashionable or Trendy diets that may or may not actually help in reducing weight. These diets should be used with caution and a professional medical opinion sought.

Fat Soluble—Able to be dissolved in fat; relating to vitamins, 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.

 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.

 Health - The overall condition of an organism at a given time in regard to soundness of body or mind and 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.

I

 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.

L

 LDL See low-density lipoprotein.

Lipid is simply another name for dietary fats or triglycerides.

 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

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.

Obese, Obesity - The condition having and increased body weight caused by excessive accumulation of fat. This is usually indicated as having a Body Mass Index in excess of 30.

Omega-3s: Essential Fatty Acids found primarily in cold-water fish and purified fish oils, omega-3s are the building blocks for "good" eicosanoids.

Omega-6: An Essential Fatty Acid found in protein and most seed oils, Omega-6 can generate both "good" and "bad" eicosanoids.

Omega-9: An essential fatty acid that has neutral effects on hormone production, i.e. does not produce "good" or "bad" eicosanoids.

 Phentermine - An appetite suppressant 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 macromolecules that are the basic building blocks of all living cells and are therefore essential in the diet of animals for the growth and repair of tissue.

R

Back to top

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 who is a food and nutrition expert. A person who has studied diet and nutrition at an American Dietetic Association (ADA) approved college program and passed an exam to become a registered dietitian.

Resting Heart Rate (RHR) is the amount of times your heart beats per minute while you are at rest. For most accurate results, the RHR should be taken in the morning before getting out of bed.

S

Back to top

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 specifically designed to build muscle and increase strength. Strength training also helps to maintain the amount of bone in your body and can help maintain weight.


Sucrose - A crystalline form of fructose and glucose found in many plants and extracted as ordinary table sugar.

T

Target Heart Rate (THR) is an estimate of how fast your heart should beat during exercise to reach a specific fitness goal..

 
Tenuate - An Appetite Suppressant that works by stimulating 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.

U

Very-low calorie diet Also called “VLCD.” A person following a VLCD eats or drinks a commercially prepared formula that has 800 calories or less, instead of eating food. A VLCD can allow a person to lose weight more quickly than is usually possible with low-calorie diets, but should only be used under the supervision of a health care provider.

 Vitamins: Various organic substances that are essential in minute quantities to the nutrition of most animals and plants. Though we produce some vitamins within our bodies, we need to obtain others via the foods we eat.
