Your analogy doesn't really apply to anyone with type 1 diabetes, which is an autoimmune disorder and roughly 10% of all diabetes cases. A lifestyle change cannot fix type 1 diabetes.

Additionally, partial remission in type 2 diabetes has a success rate of just 0.007% per 5 year post-remission cohort. The idea that a lifestyle change can "fix the damaged driveway" is essentially a statistical anomaly - it's not grounded in evidential standards has yet to be proven.

What factors contribute to the poor success rate?

Does it matter? A success rate of 0.007% is practically a statistical error. It signifies that the method is not feasible regardless of individual factors.
