There are a few things that have been useful, though I'm not sure if they were recent but considering how we in the US were raised to eat they've helped me quite a bit: the effect of low-carb diet and intermittent fasting on insulin resistance are the two that have helped me recently.

There have been some interesting studies on intermittent fasting. Refined sugar has been identified as a thing to avoid. We have reversed a lot of flawed studies (IE fat is bad).

I'd expand those recommendations a little bit:

- Exercise regularly

- Eat a variety of fruits and veggies

- Don't overeat, especially junk food (we can argue over which foods are good or bad for you, but a lot of our diets consist of things such as potato chips that are obviously bad for you, at least in large quantities)

- Stay hydrated

- Don't be too stressed

Sleep? ;)

Yeah, the whole appeal of the supplement industry, exercise infomercial contraptions, and insulin regimens for T2 diabetes is that they don't require lifestyle change which is the whole challenge of being healthy.
