Arthritis & Weight: How Excess Pounds Damage Joints & Science-Backed Weight Loss

Mechanical & Metabolic Impact

• Load multiplier: Each 1 lb weight loss reduces knee joint load by 4 lb per step.
• Adipokines: Visceral fat secretes leptin, adiponectin, IL-6, TNF-α driving synovial inflammation in OA and RA.
• Cartilage degradation: Mechanical stress + inflammatory mediators accelerate matrix breakdown.

Weight-Loss Benefits for Arthritis

• Pain reduction (WOMAC pain ↓ 30–50% with 10% weight loss)
• Improved function & mobility
• Lower systemic inflammation (CRP, IL-6)
• Delayed joint replacement
• Better medication response

Safe, Sustainable Weight-Loss Plan

1. Goal: 0.5–1 kg/week; 5–10% body weight initial target.
2. Diet: Mediterranean/DASH pattern; 1.2–1.5 g protein/kg; high fiber; limit ultra-processed foods, added sugars.
3. Exercise: 150 min moderate aerobic + 2× resistance/week (joint-friendly: water, cycling, bands).
4. Behavioral: Self-monitoring, stimulus control, problem-solving, sleep ≥7 hours.
5. Medical: Review obesogenic meds; consider GLP-1 RA if BMI ≥30 (or ≥27 with comorbidity) per guidelines.

Before Starting

Consult physician/PT for personalized plan, especially with severe joint damage, cardiovascular disease, or prior eating disorder.
