Science and nutrition is confusing. But these are all the reaserch based information, so pick whatever that works for you.

I try to dig deeper and then conclude on the truth.

Eat a moderate protein and high carbs diet

As you age increase your protein intake, because you will loose muscles.

And if you can try fasting, but ask your doctor first.

Thank you so much for reading, I will try to confuse you less next time.
