A startling study from 2016 proved the finding even more definitively: two groups with type 2 diabetes were given a standardised diet for eight weeks and asked to either eat their food in the right order or eat it however they pleased. The group who ate their food in the right order saw a significant reduction in their HbA1c level, which means they started reversing their type 2 diabetes. The other group, eating the exact same food and number of calories but in no particular order, didn’t see an improvement in their condition.
