If we are all being generous with assumptions, this could very well be the reason.
I haven't seen much research on efforts of trying to predict what dietary interventions will most effective an individualized treatment basis, but I also haven't kept up a literature for five or six years.
Then again the same promises for ADHD medicine where now they are some early genetic studies showing perhaps how we could guide treatments, but the current standard of care remain throw different pills at the patient and see what they works best with the fewest side effects.
Of course dietary stuff is complicated due to epigenetics, environmental factors, and gut microbiomes.
That said progress is being made and the knowledge we have now is world's different than the knowledge we had 20 years ago, but sadly it seems outcomes for weight loss are not improving.
