LPT REQUEST: Insurance backed methods for losing weight?

Recently, I’ve decided that losing weight is the only option for me. I’ve taken on swimming and I’m fairly diligent with my exercise. However I was thinking of possibly getting a dietician, or at the very least adopt a meal plan designed for weight-loss.

Since I live in a small town it may be harder for me to access good diet professional. I was wondering if there were other reputable nationwide programs like Weight Watchers? My only requirement is insurance coverage, I’d really be keen on getting reimbursed for whichever service I use.
