You can much more easily use the physicality of your surroundings to physically deny yourself the food than you can deny yourself anxious thoughts.
With eating there are 2 components to it, mental and physical, so you have more opportunities and more options and avenues to potentially control it.
The additional options to control it should IMO make it at least some amount easier to control in the end since some people may be able to take advantage of physical controls to limit themselves where that's not an option for anxiety.
As someone that uses food as a coping mechanism for stress, I agree with the GP - if the underlying problem isn't resolved, the weight will come back.
Then explain why people have so much trouble with it without resorting to a thought-terminating cliche
