Type 2 diabetes can be reversed, according to yet another study. It's not a chronic or progressive disease, that's just what happens when it's treated wrong.Medpage Today: Intensive Therapy Put T2D in Remission
Note that the lifestyle program wasn't even very effective, as it focused on cutting all calories. Just removing the food that turns into sugar in the body (carbohydrates) is a far more targeted and thus likely more effective approach.
Also the smart medications used in the trial (metformin and acarbose) were combined with night-time insulin. The additional insulin may lower blood glucose short therm, but it's likely counterproductive long term. Type 2 diabetes is characterized by insulin resistance, which is likely caused by frequently high insulin levels.
This study is just a sign of what is very possible - type 2 diabetes reversal. There's likely a much more effective way to do it though, using a ketogenic low-carb diet (ideally with addition of intermittent fasting):
To be frank, it's not very helpful to treat a dietary disease with medications. The solution can be much simpler - remove excess sugars from your diet, and you remove the excess sugar from your body.
