Type 1 Diabetes is something that needs lifelong treatment

Type 2 comes from bad dietary habits that include ingesting too much sugar.
Regulating that intake is hard because it is everywhere and insuling resistance comes about because your it gets harder and harder to pack more fat into your cells
BTW the result of a political decision that decided between sugar and fat as the bad guy in a diet somewhere back around 1960 if memory serves me.
The decision was controversial but won and by the sugar industry ...which had then and continues to lobby politically and influence the public into thinking it is good for you
...... by funding so called scientific conclusions experts continue to debate

You have heard of intermittent fasting I am sure
Essentially you compress "good eating" within a daily 8 hour window.
With Type 2 diabetes, the sugar levels will come down.

But of course there are now drugs to do the same..bring sugar levels down

So you can choose. eat lots of sugar and take drugs to counter the effects
or
intermittently fast and reduce sugar

You WILL lose weight and your long term sugar levels will slide below the diagnosis threshold.

Now I am sure it will not work with everyone and everyone should talk about it with their doctor.
Google Dr Jason Fung if you are interested in this at all.
