Weight Loss ..
Intentional weight loss is the process of consciously making and executing a plan to decrease total body weight. This usually entails the reduction of total body fat. Ideally, dieting should be done by eating a nutritionally balanced low-calorie diet and increasing physical activity.
Diet
Refers to the food an individual consumes. Also a special or limited selection of food and drink, chosen or prescribed for health or to gain or lose weight.
- Adipose
This word means fatty; consisting of or containing fat.
- Amino Acids
Nine of these essential `building blocks of proteinsā cannot be manufactured
by the body alone and so have to be provided though food intake. People
following a Vegan diet should be aware that it is not possible to receive
all necessary amino acids through consumption of vegetables alone. (See
Proteins and Vegan Diet).
- Anorectic Drugs
These are drugs used to make people eat less food by suppressing a personās
appetite, and therefore lessen the intake of calories. (See Calorie).
- Artificial Sweeteners
These variously named chemicals have lower calories than the sugar they
replace.
- BIA (Bioelectrical Impedance Analysis)
This is a method for the estimation of how much body fat is present in a
person, by passing a safe electric current through their body. The flow of
the electricity is made more difficult by higher amounts of fat, and
conversely, the currentās flow is easier if less amounts of fat are present.
So the flow of current is then measured to provide the body fat percent
reading. (See Body Fat).
- Blood Sugar Levels
The level or amount of glucose in the bloodstream. (See Glucose).
- BMI (Body Mass Index)
This is a very common method of evaluating individual people to see if they
are under or overweight. It involves comparing their weight to their height
by dividing the weight measurement (expressed in kilograms) by the square of
the height (expressed in meters). A BMI of below 18.5 is underweight,
between 18.5 and 25 is an indication of healthy weight, 25 to 30 is
overweight, a BMI of over 30 is referred to as obese, over 35 is known as
morbid obesity, and over 40 indicates extreme obesity.

- Body Fat
This is the percentage of a personās body mass that is not made up of
either; bones, muscles, organs, or water.
- Caffeine
A plant derived stimulant often to be found in many foods and drinks.
- Calorie
A calorie is a unit of heat energy used in determining nutritional values.
When foodstuffs, the `fuelā for the body are metabolized, they liberate
varying amounts of energy as heat. This energy is expressed in calories,
hence the term; `burning the caloriesā. Fat produces 9 calories per gram;
alcohol turns out 7 calories per gram, whilst carbohydrates and proteins
each provide 4 calories per gram. Technically speaking, 1 calorie is the
measure of heat needed to warm 1kg (kilogram) of water by 1 degree
Centigrade. (Also See Carbohydrates; Fats, and Proteins, see more about
calories).
- Calorie-Free
Food must have less than 5 calories per given serving for this to be on the
label.
- Calorie Goal
A target number of calories that will allow a person to lose weight whilst
still having the energy needs of the body provided for.
- Calorific or Caloric Value
This is the number of calories in any given food or drink.
- Carbohydrates
These are compounds of Carbon, Oxygen, and Hydrogen. The word is commonly
encountered as a group name for a type of foodstuffs that includes all
sugars; which are known as simple carbohydrates, and starches and fiber,
which are referred to as complex carbohydrates. They are a major source of
energy for the body. (See Complex Carbohydrates, Fiber and Simple
Carbohydrates or read more about carbohyhdrates).
- Cholesterol
This is a fatty substance that plays an important part in cellular health;
it is both produced in our livers and obtained from foodstuffs such as organ
meat, eggs, cheese, milk and butter. Too much cholesterol, however, is a
problem. Because it is carried around the bloodstream, any excess levels are
deposited on the walls of veins and arteries; this can cause the blood
vessels to narrow, therefore decreasing the blood flow and causing heart
problems. There are different forms of cholesterol; `goodā and Ībadā. This
distinction has to do with how it is carried around the blood. Chemicals
called lipoproteins, which are combined fatty proteins are used for
transporting the cholesterol in the bloodstream, and HDL (High Density
Lipoprotein) cholesterol is known as `goodā because any excess can be sent
to the liver and dealt with, but LDL (Low Density Lipoprotein) cholesterol
cannot be, and remains to potentially clog arteries.
- Complex Carbohydrates
These are starches and fiber, like breads, pasta, rice, cereals and
vegetables. Their molecules are linked in complex chains, hence their name,
and are converted into sugars for energy release by the body during
digestion. Because these starches must be broken down, they offer longer
term energy than simple carbohydrates. (See Carbohydrates, Fiber, and Simple
Carbohydrates).
- DV (Daily Value)
In the United States, this food label term is aimed at assisting consumers
in their planning of a nutritious diet. They are developed by the FDA. (See
FDA).
- Diet
This is an allowed plan of food and drink set down for the loss of weight,
or a prescribed plan for medical reasons. The word can also be used to mean
the habitual food intake of people or animals.
- Dietary
Anything pertaining to a diet is dietary.
- Diuretic
Diuretic drugs or substances increase the amount of urine produced in the
body, and thereby can give a false impression of weight loss by reducing the
water content of the body. No fat is lost due to a diuretic, but too much
potassium can be, as well as other vital minerals and vitamins. (See Below).
- Electrolytes
These are mineral salts like calcium, magnesium, potassium and sodium. They
are necessary in any diet for healthy nerves and muscle movement. Many
people on diets use sports drinks (electrolyte solutions) to top them up,
but these can also contain added sugars. Potassium can be depleted by the
use of diuretics. (See Above).
- Energy Expenditure
This is the energy, expressed as calories, used or Īburnedā in exercise.
Exercise is often recommended as a companion to dieting for the purpose of
losing weight.
- Enriched, or Enrichment
These are processed foods that have nutrients added to them, either to
enhance the original or to replace any nutrients that were lost in the
processing.
- Essential Fatty Acids
These are fats that must be in a diet for good health. They are principally
gained from vegetable oils. (See Fat).
- Exchange Diet / Plan
This is a weight loss plan where foods with equal calorific values are
divided up into separate groupings. The person on the diet can then
interchange foods from within each list at mealtimes to allow for more
choice and variety within the dietary regime. (See Below).
- Exchange Lists
These are the lists of swappable foodstuffs that have been divided up
according to their energy and nutritional qualities for the purpose of an
exchange diet. (See Above).
- Extra Lean
Food labeling terminology that means there is less than 2g of saturated fat,
less than 5g of overall fat and no more than 95mg of cholesterol for a 100g
portion of meat, poultry, game meat, or seafood.
- Fad Diets
These are fashionable diets that come and go on the health scene. Often
highly controversial, they are heavily hyped with spectacular claims but
contain dubious nutritional and weight loss advice. Competent medical
opinion should always be sought before starting on any of these diets.
- Fat
Fat is necessary for human health and together with carbohydrates and
proteins, gives us the energy to live. Fat also helps us by allowing the
`fat solubleā vitamins A, D, E and K to be transported around the body and
utilized where needed. However, having too much fat is responsible for many
health concerns, and in most cultures (though not all) is considered to be
unattractive, so at any one time millions of people around the world are
dieting to reduce the fat content of their bodies.
There are different types of fat, and fats found in food are a combination
of types of fatty acids, though each holds the same 9 calories per gram,
they differ in other ways. Saturated fats (solid at room temperature) for
example, which are mainly found in foodstuffs of animal origin; butter,
cheese, cream, red meats and milk, but also in plant products such as cocoa
butter and coconut oil, may cause cholesterol in the blood to increase when
too much is consumed, risking heart disease. Unsaturated fats (liquid at
room temperature) do not raise cholesterol levels, and may help to decrease
them. They are divided into monounsaturated fats, which are found in sea
foods and vegetable oils, such as peanut or olive oil, and highly
unsaturated polyunsaturated fats, in vegetable fats like sunflower oil, to
give one example. (See also Essential Fatty Acids and Hydrogenated or read
more about fats).
- Fat-Free
A food label term that means there is less than 0.5g of fat in a given size
serving.
- Fat Replacers
There are many of these substance, either based on proteins, carbohydrates,
fiber, or different forms of fatty acids, that are used as ingredients in
various foods to mimic the applications of fat, but with much less calories.
- FDA (Food & Drug Administration)
In the United States, this is the federal government agency concerned with
monitoring and regulating food and drugs.
- Fiber
This is a generic term referring to plant structure such as cellulose. These
forms of complex carbohydrates cannot be digested by humans, but as
roughage, fiber nevertheless aids bodily health.
- Food Journal
This is a written record of all foods and drinks consumed by a person over a
given time. It can assist in personalizing dietary planning.
- Food Pyramid
A graphic aid to a healthy diet. The foodstuffs at the bottom of the pyramid
are encouraged as being low calorie - high volume, and at the top; foods are
placed that should not be consumed often, they being high calorie - low
volume foods.
- Fortified
Fortified foods or drinks are those that have had extra vitamins and
minerals added to them.
- Glucose
A very important sugar that most carbohydrates are made up of. Glucose
provides energy for our body cells after it has been carried to them in the
bloodstream; it can either be used immediately or stored for later. (See
Hyperglycemia and Hypoglycemia).
- Gram
A metric unit for weight and mass present on food labels. One gram (1g) is
one thousandth of one kilogram (1kg).
- High Calorie - Low Volume
These are foods that do not often satisfy an appetite, so encouraging more
to be consumed, even though they are high in calories. Subsequently more of
this food is eaten than necessary, leading to weight gain. (See Layered
Eating, and Low Calorie - High Volume).
- Hydrogenated
This is a fat that has been chemically altered from a liquid (oil) to a
solid fat. Margarines, for example, are hydrogenated fats, and contain trans
fatty acids. Over consumption of these can raise cholesterol in the blood
even though the original fats were vegetable oils, which as unsaturated
fats, do not raise cholesterol. (See Fat).
- Hyperglycemia
This is a condition caused by there being too much glucose in the
bloodstream, also known as high blood sugar. (See below, and Glucose).
- Hypoglycemia
A condition where there is too little glucose in the blood for good health,
also know as low blood sugar. (See above, and Glucose).
- Lactose
This is the predominant carbohydrate in milk. It is more often known as milk
sugar.
- Lacto-Vegetarian Diet
This is a diet in which vegetables and dairy products (milk, cheese, yogurt,
etc) are permitted but eggs and all meats are not.
- Layered Eating
This is a common sense approach to weight loss whereby low calorie - high
volume foods are eaten when hungry in meals before high calorie - low volume
foods are touched. This way, an appetite might be satisfied without any
unnecessary extra calorific intake. (See High Calorie - Low Volume and Low
Calorie - High Volume).
- Lean
On meat, game meats, poultry and seafood, this label being present indicates
there should be no more than 10g of fat, of which saturated fat can be no
more than 4.5g, and less than 95mg of cholesterol per 100g serving.
- Lean Body Mass
All of the body with the exception of adipose tissue (fat).
- Lifestyle Change
A step up from a diet, which can be short lasting, a lifestyle change means
a long term commitment to healthier food intake and/or exercise over the
coming years.
- Light
On food labels, this product has a third of the calories, or half of the fat
of the regular alternative.
- Lipids
This is a food group that includes cholesterol, fat and oils.
- Low Calorie
A food label term that means the food or drink must have 40 calories or less
per given serving.
