The thought that keeps me from weight loss

I continue to observe myself thinking these thoughts which prevent me from abiding by my protocol

That would taste good
I want that
You only live once

I often stop and ask myself why would you want to eat something not on protocol. My mind immediately answers “because I can”

I am highly successful. I have been thin my whole life except for during pregnancy. I gained 40 pounds after losing my 39 year old best friend to pancreatic cancer. I know my thoughts are the reason. I have observed them. I’ve been doing thought work and have studied Martha Beck and have listened to you and studied scholars before. I’ve even gotten coached. Please give me your thoughts.
