What is Obesity?
Pathophysiology
How is Obesity diagnosed
Intake of Added Sugar & Obesity Risk
Added sugar is thought to increase disease
Scientific research
Dietary treatment of Obesity
Complications if Obesity is not treated
Our bodies need carbohydrates
to provide energy we need
Good Carbs – complex (found in vegetables, beans and whole grains)
Refined Carbs – Been altered by machinery to increase its shelf life. Transforms complex carbs into simple carbs
Simple carbs have sugars
added during processing
instead of naturally occurring
sugars
RDA = 130 grams of carbs per
day and the avoidance of
simple carbohydrates (130 Carbs/Day RDA)

Image 4, Lipogenesis Process (Ijms 14 19846f2)
Lipogensis is the process that converts simple sugars to fatty acids and
synthesizes tricylglycerols through the reaction of fatty acids with
glycerol. After lipogenesis, the triacylglycerols are packaged into very
low-density lipoprotein (VLDL) and secreted by the liver and they help
transport lipids and cholesterol throughout the body. The acetyly-coA
molecules begins lipogenesis in the cytoplasm of the body’s cells. A
complex of enzymes known collectively as fatty acid synthetase
completes the fatty acid synthesis.
Carbohydrates form the major bulk of the human diet, and when they
are consumed, they must be immediately converted into energy, stored
as glycogen, or converted into fat. If the carbohydrates a person eats
produce energy in excess of what the body requires for its energy
expenditure, lipogenesis converts the excess energy from into body fat,
a source of long-term energy. If the carbohydrates consumed do not
produce enough energy to support a person’s activity level, the energy
stored in body fat reserves is used instead. (“What is Lipogenesis?”)
The most common way to diagnosis obesity is by using a Body
Mass Index (BMI).
BMI = Weight in pounds * 703
height in inches²(“The BMI Formula”)
For example: Mindy is 5’2” and weighs 145
lbs.
1) Multiply 145 * 703 = 101935
2) Find height in inches – 5 feet = 60 inches
60 inches + 2 inches = 62 inches
62 inches²=3844
3) Divide 101935/3844 = 26.52
4) Find 26.52 on chart to determine weight
category
5) According to the chart, Mindy is
overweight

Image 6, Sugar & Obesity Comparison, (Bar Graph of Childhood Obesity)
FROM NAL-USDA
1) 23 lean mean, 23 obese men, 17 lean women & 15 obese women – Has similar sugar intake however, the obese derived a greater percentage of their sugar intake from added sugar. (38-47.9%) lean (25.2-31.4)
2) Same study – Ludwig & colleagues found that for each additional serving of drinks sweetened with sugar, the odds of becoming obese increased 60%
3) Some reports disagree about a direct link between increase sugar intake and obesity however, many believe this is due to the pervasive problem of underreporting food intake, which is more prevalent and severe in obese individuals.
(“Dietary Carbohydrates – Sugar & Starches”)
According to a Harvard – School of Public Health survey about drinks with added sugar and obesity
• Average can of soda of fruit punch provided about 150 calories, almost all of them from sugar = 10 tsp of table sugar
• Greater consumption of sugar-sweetened beverages (SSB) has been linked with a greater genetic susceptibility to high body mass index (BMI) and increased risk of obesity.
• Published in the New England Journal of Medicine – “this study for the first time provides reproducible evidence from three prospective cohorts to show genetic and dietary factors- SSB- may mutually influence their effects on body weight and obesity risk”.
• Genetic effects on BMI and obesity risk among those who drank one or more SSBs per day were about twice as large as those who consumed less than one serving per month. The finding suggest that regular consumptions of sugary beverages may amplify the genetic risk of obesity. In addition, individuals with greater genetic predisposition to obesity appear to be more susceptible to harmful effects of SSBs on BMI
(“Regular consumption of sugary beverages linked to increased genetic risk of obesity”)
The CDC makes the following recommendations to treat obesity:› For Individuals
Eat more fruits & vegetables and less foods high in fat and sugar
Drink water instead of sugary drinks
Limit TV watching to less than 2 hours per day Aim to exercise 30 minutes, 5 days a week
› For communities & states Maintain safe neighbors for physical activities and parks
Advocate for quality Physical Education in schools
Support local farmers markets and programs that promote fresh, healthy eating
Adopt policies that promote physical activity (Adult Obesity)
(What Are The Benefits Of Eliminating Sugar From Your Diet?)
Obesity increases the risk of more than 30 health conditions to include:Type 2 diabetesHigh cholesterolHypertensionGallstonesHeart failureFatty liver diseaseSleep apneaGERDStress incontinenceHeart failureDegenerative joint diseaseBirth defectsMiscarriagesAsthmaAnd numerous cancers(“What is Obesity”)
