A recent article published in Diabetes Care journal (July 2015) found that eating protein first before carbohydrates led to much lower post meal glucose levels (16.8% - 36.7%) and significantly lower insulin levels at 60 mins and 120 mins after the meal.
Amazingly, this effect on food order is similar to that seen using blood sugar controlling medication and may also improve insulin sensitivity.
During this study, the carbohydrates used were ciabatta bread and orange juice, these are fast releasing, high glycemic index foods. It would be interesting to see what happened if these foods were replaced with slow releasing, low glycemic index rye bread as seen in the Metabolic Balance programme. My guess is that it would lead to an even further reduction of blood sugar, insulin response and even more favourable insulin sensitivity ratings.
