Can weight loss cause back pain?
I have answered your question and for more about the back pain . you can look over this link for more info.
It is well-established that being overweight or obese increases one's chance of experiencing lower back pain. With that in mind, it makes sense to view weight loss as a back pain treatment. Rapid weight loss, however, can cause back pain in a number of ways.
Rapid weight loss diets often revolve around the principle of ketosis, where the body burns its fat due to a decrease in the supply of sugars it receives to burn. Low-carbohydrate diets fall into this category. When cutting out grains and fruits, you will miss out on some of the nutrients you usually receive. The whole body is affected by malnutrition; muscles will not be able to function properly and may spasm or weaken, causing them to become easily strained.
