I've adopted intermittent fasting for the sake of shredding fat, oddly enough I'm finding my blood sugar control a lot better. ON top of this I lift weights three times a week and do cardio twice a week.
I've had much better blood sugar control, from my experience, no it's not bad.
As for starvation mode, I've not lose any strength when it comes to weight lifting, but can see a reduction in fat and on the scales. Diet induced ketones may appear but I'm taking my basal/bolus insulin so not fussed about those :thumbup:
