@Inzil there is a wide variety.
as general as saying white sugar is bad so avoid it. some would say honey is better because it is not processed. some would say all kinds of sugar is bad and so go carnivore or ketogenic. but some would a little sugar/carbs is okay but not much. some would say go on intermittent fasting.
what they won't tell you is to test you correctly for problems in blood sugar regulation so as to know whether there is something in you that needs to be fixed as far the ability to optimally metabolize sugar goes. some would do a test and give you a false negative ( that you don't have a blood sugar regulation problem when you actually do) and this would reinforce your thinking that carbs are really bad and that yo should avoid it at all cost.
a lot of hoops to go through as I said. and you are none the better for it.
believe it or not, I benefited from doing my research reading old books I borrowed in the public library and found the answers. this was pre-1994 which meant Netscape wasn't yet around to have the internet to mislead me thoroughly. Nowadays if I started my research off the internet, I wouldn't know to sort out fact from fiction. Lots of gaslighting going on to add to add to the level of confusion in media. Social media is no help either as it adds more noise and distracts me from focus.
