3. DEFINITION
• Obesity is a medical condition in which excess body fat has accumulated to the extent that
it may have an adverse effect on health, leading to reduced life expectancy and increased
health problems.
OR
• It is abnormal growth of adipose tissue due to an enlargement of fat cell size or increase
in fat cell no or a combination of both.
OR
It may be called as increased accumulation of adipose tissue so that the body mass index is
above 30kg/m2

9. MANAGEMENT OF OBESITY
• Weight control is defined as approaches to maintaining weight within the healthy
range of BMI.
Goals of weight management:
a. Prevent further weight gain
b. Reduce body weight
c. Maintain a lower body weight over long term
10. Target weight goals
o Short term:5-10% weight loss
o Intermediate : maintenance
o Long term : additional weight loss if desired and long term weight maintenance
For initial 6 months: weight loss
after 6 months : maintenance
11. STRATEGIES OF WEIGHT LOSS
SURGERY
PHARMACOTHERAPY
LIFESTYLE MODIFICATION
1.DIET
2.PHYSICAL ACTIVITY
13. PHARMACOTHERAPY
oOLISTAT : Decrease absorption of fat
oANOREXIC DRUGS : reducing their appetite and calorie intake
oSibutramine :reducing their appetite and increased energy
expenditure
oDIURETICS : temporary weight loss by reducing fluid retention
oSEROTONINERGIC DRUGS : treat conditions such as depression, anxiety,
migraine, and nausea, and weight changes are often an indirect effect
14. DIET
• DIETARY PRESCRIPTION FOR MANAGEMENT WILL VARY ACCORDING TO FINANCIAL,
PERSONAL ,CULTURAL ,RELIGIOUS AND SOCIAL BENEFITS.
1.Create a caloric deficit by consuming fewer calories than you burn.
2.Eat a balanced diet with nutrient-rich foods like fruits, vegetables, lean proteins,
and whole grains.
3.Control portion sizes and avoid overeating.
4.Stay hydrated with water.
5.Limit processed foods and added sugars.
6.Practice mindful eating and listen to your body's hunger and fullness cues.
7.Eat regular meals and snacks to maintain energy levels.
8.Aim for consistency and moderation rather than short-term, restrictive diets.
15. CONTROL OF BODY WEIGHT
• Considering energy expenditure, the total amount
of energy expended each day can be expressed as
the sum of its three components
1. Resting metabolic rate (RMR)
2. The thermic effect of a meal (TEM)
3. The thermic effect of activity (TEA)
16. RESTING METABOLIC RATE(RMR)
• Body’s metabolic rate early in the morning following an overnight fast and 8 h of
sleep.
• The term basal metabolic rate (BMR) also is used but generally implies that the
person fasted for 12 to 18 h and slept over in the clinical facility where the BMR
measurement would be made
This value represents the minimal amount of energy expenditure needed to support
basic physiological processes.
•
It accounts for about 60% to 75% of the total energy we expend each day.
17. THERMIC EFFECT OF A MEAL
(TEM)
• The thermic effect of a meal (TEM) represents the increase in the metabolic rate that
is associated with the digestion, absorption, transport, metabolism, and storage of
ingested food.
• approximately 10% of our total energy expenditure each day.
• This value also includes some energy waste, because the body can increase its
metabolic rate above that necessary for food processing and storage.
18. THERMIC EFFECT OF ACTIVITY
(TEA)
• It is simply the energy expended above the RMR to accomplish a given task or
activity, whether it is combing one’s hair or running a 10 km race.
• accounts for the remaining 15% to 30% of our energy expenditure.
19. PHYSICAL ACTIVITY / PT
MANAGEMENT
BENEFITS OF REGULAR ACTIVITY:
Decrease loss of fat mass associated with weight loss
Improves maintenance of weight loss
Improves cardiovascular and metabolic health independent of weight loss
Protecting against falling and bone fractures in older adults
Helping to protect against certain types of cancer
Keeps bones, joints and muscles healthy
Decreases anxiety and depression and boosts your mood
Helps you handle stress
Helps to control your weight
Helps controlling joint pain and swelling due to arthritis
Helps you feel more energetic, sleep better and improves self esteem
21. SUGGESTIONS FOR SAFE WEIGHT
LOSS
o Don't crash diet as this leads to weight gain again within 5 years.
o Aim for small slow losses, of about one kilogram per week.
o Cut down on dietary fats
o Cut back on refined carbohydrates
o Consume less alcohol
o Increase intake of fresh fruits, vegetables and whole grain foods.
o Eat less snacks
o Have a regular pattern of earing and stick to it
o Exercise for approximately 30 minutes at least a few times every week.
o Don’t eliminate any one food group, choose from a wide range of foods everyday instead
and prefer whole grain food
o Have 5-6 small meals in a day rather than 3 large meals
1) Obesity increases with age
Hyperplastic (increase in the size of existing cells ) obesity is seen in adults and is difficult to treat.
2) Hormonal changes during menstruation, pregnancy, and menopause can also affect weight regulation.
3) healthy foods, education, work environment, healthcare, stress levels, lifestyle
4) FTO (Fat Mass and Obesity Associated) gene , MC4R (Melanocortin 4 Receptor) gene , LEP (Leptin) gene , Ghrelin gene , INSIG2 (Insulin Induced Gene 2) gene
5) Reduction in physical activity without habitual reduction in energy intake is major cause of obesity.
6) Corticosteroids, insulin
7 ) bad or over eating
8 ) Overeating may be a symptom of depression , anxiety , frustration and loneliness in childhood and adults.
9) Family behavior or eating habits
10) endocrine factors, including hormones like leptin, insulin, thyroid hormones, cortisol, and sex hormones, play a significant role Imbalances in these hormones can contribute to weight gain
11) positive for men negative for women , disruption of metabolic processes , Excessive alcohol consumption, especially when combined with poor dietary habits,
12) Smokers weigh less than ex-smokers WHAT CAUSES WEIGHT GAIN AFTER QUITTING? 1 Feeling hungry 2 Having heavy snacks and alcoholic drinks 3 Burning calories at a normal rate again
1 ) gastric bypass, duodenal switch.
2) fat-removal procedure used in plastic surgery.
3) uses ultrasound technology to target and reduce localized fat deposits
4) surgically removing a affected segment of the small intestine and reconnecting the healthy ends,
5) reroutes a portion of the small intestine
6) partial removal of the stomach when cancer or ulcer
7 ) creating a small stomach pouch and rerouting the digestive system to bypass a portion of the stomach and small intestine.
8) creating a smaller stomach pouch using staples or a restrictive band
9) jaw wiring is a dental procedure where the upper and lower jaws are temporarily wired together to restrict mouth opening
