4. Fat is a nutrient. It is crucial for normal body function
and without it we could not live. Not only does fat
supply us with energy, it also makes it possible for
other nutrients to do their jobs.
Fats are nutrients that give you energy. Fats have 9
calories in each gram. Fats help in the absorption of
fat-soluble vitamins A, D, E, and K. Fats are either
saturated or unsaturated, and most foods with fat have
both types. But usually there is more of one kind of fat
than the other.
7. 1. The main function of fats in the body is to provide
energy: By supplying energy, fats save proteins from
being used for energy and allow them to perform their
more important role of building and repairing tissues.
Fats on oxidation provide almost twice as much energy
as that given by carbohydrates.
2. In addition to supplying energy, fats also help in
forming structural material of cells and tissues such as
the cell membrane.
8. 3. Fats also carry the fats soluble vitamins A, D, E and
K into the body and help in the absorption of these
vitamins in the intestines.
4. Some fats supply essential fatty acids.

10. How much is too much body fat?
It is generally accepted that men should have less than 18%
total body fat and women less than 23% and that an excess
is not particularly hazardous to health until levels reach
35% and 40% total body fat respectively.
So what is percent body fat?
Percent body fat is the percentage of the total body that is
fat. Thus someone who weighs 150 pounds and is 10% fat
has 15 pounds of fatty tissue.
Where does body fat come from?
Fat is produced by the body when the diet provides the
body with more calories than it needs for general
maintenance and its current level of physical activity
11. How do I lose excess fat?
The removal of excess fat is achieved by consuming
less calories than the body requires. The body's fat
stores will be broken down to address the deficit.
How does exercise affect body fat?
An increase in regular exercise will help to increase
your calorie expenditure. The more physical activity
you do the more calories you will burn. Accordingly, if
you increase your physical activity, and do not increase
your intake of food, you will draw the extra energy
needed from your stored body fat.

13. Low-fat diets can actually increase the risk of heart
disease, new research has revealed.
For years people wanting to protect their hearts have
avoided eating fatty foods such as red meat and dairy
products.
But the study suggests that low-fat diets weaken the
immune system and slow the body’s healing process and
make it less effective.
A lack of fats and cholesterol can allow damage in arteries
and veins to reach critical levels and lead to heart
attacks, strokes or organ failure.
