I'm glad to share my fat free experience - I saw an article from american research that indicated that fats ingested suppressed production of enzymes that allow the blood to sense glucose levels and take action accordingly. Without those enzymes the body was effectively blinded to BG levels. Thought I'd give it a try and cut out all fats, visible and invisible. Results were startling.
I have dry wholemeal toast (with salt and pepper - don't mock!) for breakfast, two wholemeal baps with egg or salad or both for lunch and whatever the memsahib has produced for an evening meal. This is often casseroled beef, or pork with mashed potatoes and lots of steamed veg. Nothing afterwards. Bear in mind portion control and absolutely no fats. Tonight I'm told it's steamed cod with new potatoes and peas.
I can probably dig out the article and email the link to whoever might be interested
Best wishes
