Lindlahr coined the phrase "You are what you eat" in 1942. A poll in LinkedIn shows that 93% of voters still uphold the belief. However, the trend of overweight and obesity from 1902 to 2000 in the United States is still climbing uploads. The death rate from obesity in the United Stats is four times higher than of Japan. This could be attributed to Japan's low rate of obesity, low consumption of red meat and high consumption fish and plant foods such as soybeans and tea.

▪ Homeostasis is a state of balance within all physical systems
needed for a body to function properly and survive..
▪ In a state of homeostasis, body levels are constantly adjusting
in response to changes outside and inside the body.

12. Body mass index (BMI): a measure of body fat
▪ Body mass index (BMI) is a value derived from the mass and height of a person.
▪ The BMI is defined as the body mass divided by the square of the body height.
The mass is expressed in kilograms. The height is expressed in meters. BMI is
expressed in units of kg/m².

14. The composition of fat in the body
▪ The human body is made of muscle tissue,
essential fat, non-essential fat, bone and
other organs.
▪ In an adult male ,45% of the body
composition is muscle tissue, 3% is
essential fat, 12% is non-essential fat, 15%
is bone and 25% is made of other organs.
▪ In an adult female, 36% of the body
composition is muscle tissue, 12% is
essential fat, 15% is non-essential fat, 12%
is bone and 25% is made of other organs.
▪ Essential fat is what the body needs for
maintenance of health. Non-essential fat
is a depot for fat storage.
▪ There is a close correlation between body
fat and body mas index (BMI).

equal to or greater than 30. BMI is a person's weight in kilograms divided by his or her height in metres squared.

18. Comments
▪ A poll in LinkedIn shows that 93% of 42 voters from 2,364
impressions believe in “you are what you eat”.
▪ However, 5 studies on the trend of obesity and healthy weight
from 1902 to 2000 do not agree with the current belief.
▪ In addition, the death rate from obesity in the United States is
four times higher than that of Japan.
▪ This low mortality is mainly attributable to a low rate of
obesity, low consumption of red meat, and high consumption
of fish and plant foods such as soybeans and tea.
▪ In Japan, the obesity rate is low (4.8% for men and 3.7% for
women).
▪ In United States, two out of three U.S. adults are overweight
(69 percent) and one out of three is obese (36 percent).
▪ Overweight and obesity have reached epidermic proportions in
United States. The prevalence of high BMI in the population
suggests that high food intake or low energy output is the
root of the problem.
