Would a coach be able to help me, would it be helpful?

Weds ELLIPTICAL 60 mins
Thus treadmill RUN 4 miles out of 5.5

Skipped strength sessions because I needed to get home (to LA, and..., haha)  and skipped the commute because we were driving together. A bit of a sin today, because it's upwards of 50F, sunny, and drier. Oh well. 

Today's run felt great, no comments, stayed lower than my limit as planned. Although the initial plan was for only 3 miles...

I've been listening to more podcasts lately, and found one guy who is a coach for sports nutrition. And I wonder, would someone like this be able to help me? His 6 steps are what I listened to on the treadmill today: eat real food, don't snack, strength training, fix the mental problems, lower stress, and of course hire him as a coach. Summary: low carb, some IF, change the habits and problems with food, etc. 

Nothing changes, if nothing changes is what he said. 

It's been a year now of trying and trying to get back to fitness. OK sure, surgery put a lot into pause, I had a terrible stress and M problem this spring, but now for weeks I'm trying to improve body composition without any change. I added in cardio, and added food to compensate, so no change means no change? 

I'm eating more variety than before. I've figured out that tapioca starch is bad for the gut (gas and cramps). I'm still learning. But I'm still spinning my wheels with no progress for the past few months. What do I expect? What do I want? And what would he be able to do for it?
