i heard from someone that their doctor told them this tidbit of information. And I have noticed that since I have started diet that my back feels better. Do we think it has any truth?

    Not sure what you are saying.

    Pressure isn't measured in pounds, so how you can have six pounds of pressure.
    Also, since we have the whole muscle is denser (not heavier!) than fat, does that mean it generates even more pressure, as it will be over an even smaller area?

    I don't know the exact math of 6:1 or some other ratio, but the fact is with every step you take your legs and/or back make contact with the ground and have to absorb the inertia of your body being pulled by gravity, so for a split moment your limb has to resist far more than your normal body weight.

    Just speaking from personal experience, I know my knees used to hurt on stairs long before my leg muscles would give out, but after losing 50# my knees stopped objecting.

    psi= pounds per square inch........

    The thread title and post make no sense.

    Sorry! I didn't know how to get it across! I was super tired last night.

    So hopefully I make sense now. For every pound you lose, you lose 6 pounds of pressure off your back, legs, and feet. Gravity reasons maybe?

    I was just wondering if anyone could clarify this.

    Yes, in the USA, you could say 6lb of pressure and anyone who has inflated a tire would know you mean PSI.

    However, the thread title still makes no sense. 1lb = 6lb of pressure over what area? Even with the further explanation, it still doesn't make sense, because my back wasn't under 300lb of pressure. My skin would have blown out at that point and the fat would have fallen to the floor.

    pounds per square inch isn't pounds, just like miles per hour isn't miles.

    Seems like she's asking if it's true that extra bodyweight multiplies the load on the body, because her back felt better when she lost weight. The answer of course is yes, but the exact number depends on the activity - running produces more force than walking, for example.

    The improved back pain could also be because of reduced visceral fat, which enables the abs to support the back better.

    OP I didnt find figures for back or feet, but its along the idea that the moreweight you lose then the less pressire there is on your joints. I didnt see anything that said 1-6 ratio and its a bit dubious hwere that figure came from but theres been a study, which indicates for each 1lb loss can result in 4lb less weight pressure on knees. This is significant for people who suffer from osteoarthritis. Obviously the less you weigh, then the less pressure there will be on all your joints and resultant wear and tear.
    Weight Loss Takes Pressure Off the Knee

    Osteoarthritis is the leading cause of disability in the U.S. The disease progressively destroys the cartilage that acts like a shock absorber in the joints and results in pain, stiffness, and eventually loss of movement in the affected joint.

    The study involved 142 overweight and obese older adults with osteoarthritis of the knee who participated in an 18 month weight loss program.

    By the end of the weight loss program, the participants lost an average of nearly 3% of their body weight.

    But when researchers measured the load on the knee joints, they found that each pound of weight loss was associated with a 4 pound reduction in knee-joint load.

    Accumulated over thousands of steps taken each day, researchers say the effects of this reduction of pressure on the knees should have a significant impact on the progression of osteoarthritis of the knee. They say more studies are needed to confirm this assumption.
