whirleywoo I was also diagnosed about 3 weeks ago, and the only way I could manage my sugars at first was to cut carbs. I was starving and losing weight and my endocrinologist told me off about this.
It's important you see a diabetes educator or dietician to go through what you should be eating. Mine has told me it it much better to be on insulin but be eating the correct amount for the growing baby, than to just eat enough to keep the sugars under control. I have to eat 6 times a day to be having enough calories without constantly tipping the levels over. It's a bit weird as I'm not a natural snacker.
I am going onto insulin on thursday as I can't keep all my readings below 7, even though I have been utterly strict on the diet and haven't cheated with one mouthful.
I can't lie, it is a bit of a pain, especially when I come in late and would normally have a bowl of pasta, beans on toast or a jacket potato, all of which sent me over, but you do get used to it.
I'm trying to see food as fuel for the baby only for the next few weeks and count my blessings that hopefully this will go away once I deliver and I can go back to eating a more relaxed diet.
Things I have found that work well as quick meals are omelette with a couple of potatoes and a salad, egg on toast, chilli with brown rice, spag bol with brown pasta, any stews/casseroles, steak and veg and potatoes and I make sure I bulk everything out with veg and pulses if possible.
For snacks I have yogurt with nuts and berries, hoummous on toast, slice of cheese on toast, cheese and vegemite on toast, fruit.
I am not overweight so I haven't cut back on higher fat things - so I eat nuts, hoummous, cheese etc as and when I fancy it.
I have also discovered a zero sugar chocolate which although not being as nice as a mars bar, does take away the sweet cravings - check in the "health" or diabetic section of the supermarket.
