    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
