If there's one factor that most powerfully influences knee pain and cartilage wear, it's body weight. The relationship isn't one-to-one — it's multiplied — which is exactly why managing weight is one of the most effective things you can do for your knees.

The load multiplies with every step

When you walk, each knee carries several times your body weight because of the forces involved in moving. Studies estimate the load through the knee is roughly three to four times body weight during walking, and even more on stairs. That means each extra kilogram you carry translates into several extra kilograms of force pressing through the joint — thousands of times a day.

Weight, inflammation, and cartilage

Extra weight doesn't only add mechanical load. Fat tissue is metabolically active and releases inflammatory signals that can accelerate cartilage breakdown throughout the body. This is part of why excess weight is one of the strongest risk factors for developing knee osteoarthritis.

The encouraging part: small changes, big relief

You don't need dramatic weight loss to help your knees. Research consistently shows that losing even a modest amount of body weight meaningfully reduces knee pain and the force through the joint. Because the load is multiplied, a small reduction on the scale becomes a much larger reduction in the pressure your cartilage feels.

How to lighten the load — sustainably

  • Combine gentle activity with nutrition. Low-impact exercise (walking, swimming, cycling) burns energy without pounding the joint.
  • Build muscle. Strength training raises metabolism and directly stabilizes the knee.
  • Focus on whole foods. More vegetables, protein, and fibre; less ultra-processed food and sugary drinks.
  • Aim for steady, lasting change rather than crash diets — your joints benefit from consistency.

Support cartilage while you protect it

Reducing load protects your cartilage from the outside; collagen supports it from within. Mafsal Riyadi is a dual-action collagen supplement designed to help build and protect cartilage over the long term — a licensed dietary supplement (EDA reg. no. 14711/2026).
