I was wondering if anyone knew what an insurance company's expectation is for the 6 month medically supervised diet. Thank you!

It depends on the insurance company. I had NO requirement. I met my doctor and had surgery 2 months later. Others will accept things like Weight Watchers. I would ask your surgeon's office to check with your insurance. Most surgeons want to move you along as quickly as makes sense.

That's true some don't even have a goal just monthly check in of weight...

My insurance (Cigna) required I had to do 3 supervised visits with the dietician, each a month apart, so basically 3 months. The insurance didn’t give us any more details than that which was frustrating but the Dr. and dietician just went with what they normally did and said the insurance might want to see some weight loss even if minimal. I didn’t do a diet or anything, just food journaling, ride my bike and consultations. The dietician told me that I shouldn’t gain weight but since my BMI was close to dropping below 40 that I shouldn’t lose too much weight either. So I kept my weight loss to about 1 pound a month. Worked out fine, insurance approved my request right away.
