Yes even before joining the low carbohydrate program - I had started reading about wheat grains oils that are liquid at room temperature and based on corn etc.
And went cold turkey on breads etc. started adopting a Keto approach and reversed my hbA1c to pre diabetic values very very quickly. Ignoring UK NHS diabetic nurse and doctor and the various nutritional advice courses that I was sent on.. Luckily there are doctors out there that do take an interest and read beyond the headlines of nutritional papers and misinformation.
Took me three weeks to get over my bread, pastry, sandwich, pasta cravings - but now I feel no pull toward these at all now - but I believe full fat no grains and oils - olive oil excluded - is the way - but hey unless you cook everything yourself - it is a minefield - seeds/vegetable oils - I believe the dangers..
