I follow a fairly well established 4 meal a day plan (no snacks)

Each meal is 4 to 5 hours apart and I aim for each meal being "about" 500 calories and target 25 carbs (but can vary up to 30 or 35 with some meals)

I determined what I could eat by testing before and after a given meal, at least 3 or 4 times over the course of a few months (yes, lots of stick tests) and determined which meals with a given portion size were "safe" and if they weren't, small adjustments were made until there were safe to eat

It took us decades to develop the bad eating habits which certainly contributed to our diagnosis. So we should not expect to change the way we eat overnight. It took me a good two years to get my "new way of eating" established and I have tweaked it over the past 6 or 7 years - it constantly evolves

Thank you for the message. This is my journey now.
