I lost weight and my stutter becomes significantly better

I lost weight and my stutter becomes significantly better During Covid, I gained some weight (over 20 pounds) and I noticed that my stuttering has become all time worst. Before, I thought that only way for me to “regulate” it was to sleep well, speak slow and some emotional tricks (which did/did not work). But lately I have been on my weight loss journey and noticed that every time I dress nice and feel confident about my appearance, I barely stutter. Probably I am speaking a common sense and everyone already knew this but it made me so happy to realize something so simple (or not really) can affect my stutter this much. I would appreciate if you can share similar experiences
