Carbs causing pain?

I don't know about carbs but know anti-inflammatory diets call for discontinuing sugar.

It's a good question.

As you are seeing results from personal experience. I don't know, nor will claim to know, but I do only want to add that some, and I am not going to state how often, which studies, or make general statements, but there are those who are referring to this inflammation and Keto as the inflammation around cells which prevent the cell receptors from working correctly. Thus, some feel certain carbs add too much inflammation and that is why some experience a frustrating stop in weight loss. As if they are doing everything correctly but no longer losing weight. This opens up discussions on dirty keto to pasture fed, so watch out. But they then list culprit foods (mainly certain carbs or oils most do not use on the Keto diet. Soyben, grape, peanut, etc...) that may be causing the inflammation, and again, stopping cell receptors, due to carb resistance , which stops the hormones from communicating with the cell. Which changes how weight is lost. (Warning * possible rabbit hole to go down.)

I know you are inquiring as to physical inflammation for this particular question. I am just stating while you research this, you may find varying topics on inflammation. And wouldn't be surprised if some views combine the two, either theories or hypothesis.

There are, I am sure, others who support the inflammation being more physical with joint pains. I have nothing to add there. I am only saying what one may find when looking into this subject.

Glad you found a way to go back to running, sprinting squatting and jumping. Good for you. Stay healthy!
