Study Notes

Obesity

Characterized by excessive fat accumulation due to chronic energy imbalance
Adipose tissue dysregulation:
- Increased adipocyte size (hypertrophy) and number (hyperplasia)
- Promotes insulin resistance, chronic inflammation, metabolic disorders (T2DM)
Hormonal imbalances:
- Leptin resistance (reduced sensitivity to satiety hormone)
- Ghrelin dysregulation (increased hunger)
- High cortisol due to stress and poor sleep can increase abdominal fat
Microbiome disruption (gut dysbiosis):
- Linked to metabolic endotoxemia, promoting insulin resistance and weight gain

Strategies for Reducing Obesity

Dietary Changes:
- Calorie deficit: 500-750 kcal/day
- Low glycemic index (GI) and high-fiber diets with adequate protein
- Avoid processed foods, sugars, artificial sweeteners, and refined carbs
- Support gut health through a high-fiber diet (40-50 g/day) and probiotics
- Meal timing: Time-restricted feeding (TRF) and early dinner
Exercise:
- Daily moderate-intensity exercise increases insulin sensitivity and activates AMPK, promoting fat burning
Sleep and Stress Management:
- Adequate sleep supports glucose tolerance and balances ghrelin and leptin levels
- Reduce stress to lower cortisol and avoid stress-related overeating

Nutrients and Supplements for Obesity

5-HTP: 50-100 mg twice daily to enhance satiety and promote sleep
Green Tea Extract (EGCG): 600-900 mg daily to promote thermogenesis and fat oxidation
L-Carnitine: Up to 2000 mg daily to support fat metabolism and improve leptin resistance
Conjugated Linoleic Acid (CLA): Up to 3.4 g daily to enhance fat oxidation and improve insulin sensitivity
Chromium Picolinate: 200-1000 mcg daily to reduce carbohydrate cravings and support glucose metabolism
Gymnema Sylvestre: 100 mg three times daily to regulate blood glucose and reduce sugar cravings

Anorexia Nervosa (AN)

Characterized by extreme calorie restriction, fear of weight gain, and distorted body image
Leads to nutrient deficiencies, muscle atrophy, low body temperature, and hormonal imbalances (low serotonin and estrogen)
Long-term starvation can result in electrolyte imbalances, osteopenia, and cardiovascular complications

Bulimia Nervosa (BN)

Involves binge eating followed by compensatory behaviors like purging (vomiting, laxative abuse), or excessive exercise
Results in erratic weight changes, tooth erosion, sore throat, and gastrointestinal issues
Linked to acute tryptophan depletion, which reduces serotonin levels and increases the urge to binge

Binge Eating Disorder (BED)

Similar to BN, but without compensatory behaviors
Characterized by eating large amounts of food in a short period, often triggered by stress, food deprivation, or emotional distress
Associated with obesity and psychological distress

Strategies, Nutrients, and Supplements for Eating Disorders

Protein and Tryptophan:
- Increase tryptophan-rich foods or supplements to enhance serotonin levels and reduce binge urges
- Protein supplementation may accelerate recovery
Zinc: 14-45 mg daily to support weight gain in AN and improve anxiety and depression
Inositol: 18 g/day for BN and BED to improve serotonin receptor sensitivity and reduce binge episodes
B Vitamins: To support neurotransmitter synthesis and improve mood regulation
Probiotics: Use Lactobacillus strains to improve digestion and immune function during recovery
