This outline provides a comprehensive structure for a presentation on obesity, covering its causes, consequences, prevention, management, public health approaches, and future directions. It can be expanded into a detailed presentation with in-depth information, case studies, and visual aids.
3. Definition of obesity
OVERWEIGHT AND OBESITY ARE DEFINED AS ABNORMAL OR EXCESSIVE FAT
ACCUMULATION THAT PRESENTS A RISK TO HEALTH - BY WHO
4. Causes of obesity
DIET- Diet and lifestyle factors contribute to development of obesity and
overweight. Some of the most common ones are : eating large amounts of
processed or fast food – this is food that's high in fat and sugar drinking too
much alcohol – alcohol contains a lot of calories eating out a lot – food
cooked in a restaurant may be higher in fat and sugar eating larger portions
than you need drinking too many sugary drinks – including soft drinks and
fruit juice.
5. Treatment of obesity
Making healthier choices. -To make your overall diet healthier,
eat more plant-based foods. These include fruits, vegetables and whole
grains. Also emphasize lean sources of protein — such as beans, lentils
and soy — and lean meats. If you like fish, try to include fish twice a week.
Limit salt and added sugar. Eat small amounts of fats, and make sure they
come from heart-healthy sources, such as olive, canola and nut oils.
Restricting certain foods. Certain diets limit the amount of a
particular food group, such as high-carbohydrate or full-fat foods. Ask
your health care professional which diet plans are effective and which
might be helpful for you
6. Meal replacements. -These plans suggest replacing one or two
meals each day with their products — such as low-calorie shakes or meal
bars — and eating healthy snacks. Then you have a healthy, balanced third
meal that's low in fat and calories. In the short term, this type of diet can
help you lose weight.
Exercise and activity Getting more physical activity or exercise is an
essential part of obesity treatment:
Exercise. People with obesity need to get at least 150 minutes a week of
moderate-intensity physical activity. This can help prevent further weight
gain or maintain the loss of a modest amount of weight. You'll probably
need to gradually increase the amount you exercise as your endurance and
fitness improve.
7. Keep moving.- Even though regular aerobic exercise is the most
efficient way to burn calories and shed excess weight, any extra movement
helps burn calories. For example, park farther from store entrances and
take the stairs instead of the elevator. A pedometer can track how many
steps you take over the course of a day. Many people try to reach 10,000
steps every day. Gradually increase the number of steps you take daily to
reach your goal.
8. BMI-BODY MASS INDEX
INTRODUCTION: Adolphe Quetelet, a Belgian astronomer, mathematician,
statistician, and sociologist, devised the basis of the BMI between 1830
and 1850 as he developed what he called "social physics
9. CALCULATION OF BMI
Calculation of BMI: BMI is calculated by dividing the subject's weight by the
squans of his her height, typically expressed either in metric or "US customary
units. It is calculated by the following equation: BMI Body Weight (Standing
height in meter)For example: BMI is calculated by using the body Mass Index
formula. Height in cm Weight in kg.
Once the BMI member is determined, the following table is used: BMI Less
than 18.5 Weight status Under weight
18.5-24.9 NORMAL WT.
25.0-29.9 Over weight
30.0-34.9 Class I obesity
35.0-39.9 CLASS 2ND Obesity
Over-40.0 class III obesity
