You can't come on here and ask for help and not expect the forum members to give their help and opinions. There are some very experienced and successful people on here, and the really successful ones are not going to sugar coat it.
You want to defend your nutritionists approval of a full sugar drink and yet complain when posters point out that obvious issue.
Change is hard, but humans generally run from it. Also deep introspection that elicits lasting change usually takes a huge painful event, and not subtle gentle hints. A friend died, boom and he was only a couple years different in age from me - he and his wife - wonderful people, but both obese. I did not want to be that person, at the least I would die having tried to really change. You are early in the journey, and we all get impatient, there will be stalls, frustrations, maybe even a set back - but just keep going.
