Body Weight and Knee Load: Why Every Kilogram Counts
Share
Body weight is a sensitive topic, and nobody likes to hear that they should lose a few kilograms. But when it comes to knee pain, it is one of the factors you can actually change. The knees carry the weight of your body with every step, every stair and every time you get up from a chair. This article explains how weight and knee load are connected, why even small changes can matter and how to start in a way that is kind to your joints.
Why every kilogram counts
When you walk, the force on the knee is considerably higher than your body weight, and on stairs, slopes and when squatting it rises even further. That means every extra kilogram is felt many times a day, step after step. Over the years, this extra load can wear on the cartilage and make existing knee problems more noticeable. The good news works the same way in reverse: every kilogram less means less load on the knees with every step.
More than just load
Extra weight affects the knees not only through pressure. Fat tissue is active in the body and is linked to processes that play a role in inflammation. That may be one reason why weight is also connected with pain in joints that do not carry body weight, such as the hands. Extra weight also often goes together with less movement, weaker muscles and poorer sleep, and all of these can make knee pain worse. More about this is in our article on risk factors for knee osteoarthritis.
Small steps that make a difference
- Set a realistic goal. Aim for slow, steady progress rather than fast results. Changes you can keep up bring more than a strict plan.
- Move every day. Choose activities that are gentle on the knees, such as walking on flat ground, cycling or swimming. Our article on cycling and swimming with sore knees has practical tips.
- Change your plate. More vegetables, fish and simple foods, fewer sweets and processed products. Ideas are in our article on anti-inflammatory foods for your joints.
- Watch your drinks. Sweet drinks and alcohol bring a lot of energy without filling you up. Water and unsweetened tea are better everyday choices.
- Sleep and rest well. Too little sleep and a lot of stress often make it harder to eat in moderation and stay active.
Exercise with extra weight
Many people with extra weight avoid exercise because their knees hurt. But gentle movement is an important step toward the solution. Start with low-impact activities and short sessions, then add simple strengthening exercises for the thighs and hips. Strong muscles take load off the joint and make everyday movements easier. You can find suitable exercises in our article on knee strengthening exercises at home. Avoid jumping, running downhill and deep squats at the beginning.
When to get support
If losing weight is hard for you, you do not have to do it alone. A doctor can look into possible medical reasons for weight gain and help you plan changes safely, and a nutrition specialist can help you find a way of eating that fits your life. See a doctor if your weight changes quickly without a clear reason. Avoid crash diets, because they are hard to keep up and can weaken your muscles. On the way to more movement, a soft knee sleeve can make walks and exercises more comfortable, because it gives a feeling of support and keeps the knee warm.
