The Pain Solution Does Not Need To Be Your Weight
The physical pain you may be experiencing does not need to be attributed to the weight on the scale.
Here's why: You did not become that weight overnight. And people can experience pain regardless of weight.
Injuries can occur from doing too much too soon. Like trying to squat too much without adequate recovery and adaptation.
So if weight was supposed to be the cause of pain, then you would have to have dramatically changed your weight. And fast. I really doubt this is the case for most people.
Your body is adaptable. That includes your body weight.
Pain is not as simple as saying that if you lost 20lbs your pain would be gone.
It's a false narrative that can promote unhealthy diet culture and lead to people not getting the treatment and care they need because of their weight.
Pain has multiple factors worth investigating. Thankfully the activities that can influence weight loss can also influence pain (sleep, stress, physical activity, nutrition). Weight loss may help your pain, but it's probably not the only thing going on.
If you want to lose weight while reducing pain, great. If not that is totally fine as well.
