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 2 ND Obesity Over-40.0 class III obesity
