Sometimes, but not always. I know at least a couple type 2 diabetics who aren't overweight, eat generally healthy diets, and get regular exercise - but still require medication to control their blood sugar. And that's leaving aside the very real difficulties most people have in making the lifestyle changes necessary to affect the disease.
> 60% of patients enrolled one year attained an HbA1c below 6.5% without the use of diabetes medications other than metformin.
60% reversal without medication except for the major frontline medication for type 2 diabetes doesn't make it sound like a miracle cure, tbh. And it's still has the "major lifestyle changes that are typically hard for people" problem.
No one claimed that the treatment protocol is a miracle cure, so you're arguing against a strawman. But the results show that it does work well for many patients. They literally did make those major lifestyle changes, with support from their healthcare providers.
If you know a type-2 diabetic then I would at least point this out as an option. Some of them might choose to pursue it as an alternative to permanent dependence on exogenous insulin which doesn't even address the root cause of the condition.
