I might have been one of the posters you are referring to. I wish I had fully documented my protocols, as I threw the kitchen sink at diabetes. What I did to start with was eat lower glycemic index carbs (home made soda bread, sweet potato), vegetables, lots of nuts and built up to extreme exercise - this was exhausting and after say a 3 mile walk, I would need something to eat. I would say my exercise was circa 750 to 900 calories a day 6 days a week; I was encouraged due to the massive swings from around 8 mmol to late 4's (mainly static cycle (2 x 30 mins a day at 90 revs per minute), this is still the exercise that makes me sweat the most, and I associated sweat with progress). This regime got me 10 kg weight loss, as I was thin-ish on the outside, fat on the in, and resulted in 41 / 42 HbA1c's - just in the normal range (on Metformin also).
The "cream" on top for me was to move to LCHF, which has yielded a more comfortable for me 35 / 36 HbA1c and a further 2 kg weight loss (now added a kilo due to additional weight training). I do not subscribe to extreme high fat of slavering my food in good fats, it is just the fact that "we" cook with either olive oil, butter or coconut oil, and eat avocados and nuts whilst reducing the usual higher carb foods. I think it is a shame that LCHF is associated with high protein Atkins 1.
Many get great results with just diet, it is said that potential reversal is 80% diet (I agree with this), I think the after-burn of exercising is a free hit on diabetes and assists with well being. Fasting is great, today I only had one meal by accident due to being at a client site for longer than I envisaged and I was not hungry.
