Weight Loss Medications

• Types:
  • Prescription medications
  • Over-the-counter (OTC) drugs
• Mechanisms of Action:
  • Reduce appetite
  • Increase feelings of fullness
  • Decrease fat absorption
• Common Medications:
  • Orlistat (Alli, Xenical)
    • Inhibits fat absorption in the intestine
  • Phentermine-topiramate (Qsymia)
    • Appetite suppression and increased energy expenditure
  • Liraglutide (Saxenda)
    • Mimics GLP-1 to promote satiety
• Effectiveness:
  • Often used in conjunction with lifestyle changes
  • Varies by individual; typically modest weight loss

Appetite Suppressants

• Function: Reduce hunger pangs and cravings
• Categories:
  • Stimulant-based:
    • Elevate energy and reduce appetite (e.g., phentermine)
  • Non-stimulant:
    • Use different pathways (e.g., bupropion)
• Potential Side Effects:
  • Insomnia
  • Increased heart rate
  • Dependence or abuse potential
• Considerations:
  • Medical supervision recommended
  • Not suitable for everyone (e.g., heart disease, anxiety disorders)

Nutritional Supplements

• Purpose: Support weight loss, metabolism, and overall health
• Types:
  • Multivitamins
  • Protein powders
  • Fiber supplements
  • Herbal extracts (e.g., green tea extract, garcinia cambogia)
• Mechanisms:
  • Provide nutrients that may aid metabolic processes
  • Help control appetite or enhance energy levels
• Regulation:
  • Less regulated than medications
  • Quality and efficacy vary significantly
• Cautions:
  • May interact with medications
  • Substitute for balanced diet, not a replacement
  • Research efficacy varies; some claims lack scientific support

Weight Loss Medications

• Medications come in prescription and over-the-counter (OTC) forms.
• Medications work by reducing appetite, increasing feelings of fullness, and decreasing fat absorption.
• Common medications include Orlistat (Alli, Xenical), Phentermine-topiramate (Qsymia), and Liraglutide (Saxenda).
• Orlistat inhibits fat absorption in the intestines.
• Phentermine-topiramate suppresses appetite and increases energy expenditure.
• Liraglutide promotes satiety by mimicking GLP-1.
• Weight loss medications are often used in conjunction with lifestyle changes.
• Effectiveness varies individually, but generally results in modest weight loss.

Appetite Suppressants

• Appetite suppressants aim to reduce hunger pangs and cravings.
• They are categorized as stimulant-based and non-stimulant.
• Stimulant-based suppressants elevate energy levels and reduce appetite (e.g., phentermine).
• Non-stimulant suppressants use different pathways to reduce appetite (e.g., bupropion).
• Potential side effects include insomnia, increased heart rate, and dependence or abuse potential.
• Medical supervision is recommended, and appetite suppressants are not suitable for everyone, including those with heart disease or anxiety disorders.

Nutritional Supplements

• Nutritional supplements support weight loss, metabolism, and overall health.
• Examples include multivitamins, protein powders, fiber supplements, and herbal extracts (e.g., green tea extract, garcinia cambogia).
• They provide nutrients that may aid metabolic processes, help control appetite, and enhance energy levels.
• Compared to medications, they have less regulation, and quality and efficacy vary significantly.
• Supplements can interact with medications, and they should not be used as a replacement for a balanced diet.
• Scientific evidence for their effectiveness is mixed; some claims lack scientific support.
