Study Notes

Overweight and Obesity

Overweight and obesity is the accumulation of excess body fat, defined by a BMI ≥ 25.
Abdominal obesity is a risk factor for cardiovascular disease and is defined by waist circumference and waist-to-hip ratio.
Waist-to-hip ratio is a measure of abdominal obesity.

Causes of Overweight and Obesity

Biological factors:
- Metabolic disorders (e.g. hypothyroid disease)
- Hormones that affect appetite and satiety
Environmental factors:
- Increased consumption of calories and decreased energy expenditure
- Calorie-dense foods
- Increased portions
Technological and sedentary lifestyle factors:
- Decreased energy expenditure
- Less physical labor and lack of exercise
Food insecurity and poverty:
- Intake of low-cost, high-fat foods
Medication:
- Some medications increase appetite or reduce metabolic rate (e.g. antipsychotics, antidepressants, mood stabilizers, anticonvulsants, and corticosteroids)

Health Risks of Obesity

Infertility
Congenital abnormality
Certain cancers
Degenerative joint disease
Gastroesophageal reflux
Kidney stones
Gallstones
Fatty liver disease

Obesity in UAE

Adult obesity in the UAE stands at 27.8% (2019)
Nearly 70% of Emirati male adults under 30 are obese (2019)

Medical and Nutritional Interventions

Weight loss is recommended (5-10% reduction)
Surgical intervention results in greater weight loss than diet and exercise
Assessment is a basis for personalized approach and customized advice
Measurement of BMI, waist circumference, and waist-to-hip ratio

Treatment Options

Weight management goals:
- Behaviors and health outcomes (short and long term)
- Addressing barriers to weight loss
- Reasonable and achievable goals
A reduction of 10% of body weight is recommended
Lifestyle modifications:
- Diet
- Physical activity
- Behavior modification
Population-specific recommendations:
- Children: not suitable for strict diets, need lifestyle modification
- Pregnant females: weight loss is contraindicated
- Older adults: careful evaluation is necessary due to risk of malnutrition

Diet and Lifestyle Modifications

Low-calorie diets:
- Range from near starvation to merely subtracting 500-1000 calories from one's baseline daily energy needs
- Risks: fluid and electrolyte loss, inadequate nutrient intake, muscle loss
Nutrient-altered diets:
- Low-carbohydrate diets: risk of ketosis, often high in fat
- Moderate fat, moderate to high carbohydrate diets: generally balanced
- Low-fat or very low-fat diets: high in carbohydrates, may lead to high triglycerides

Surgical Interventions

Bariatric surgery:
- Types: restrictive (gastric banding, adjustable banding), restrictive/malabsorptive (Roux-en-Y, biliopancreatic diversion)
- Risks: operative mortality
