Hi, I've had 8 babies now, and GD for at least 4 of them. If you are hungry, you need to eat more! I found a low carb diet with lots of protein was very filling, and I didn't feel hungry. A good typical diet was omelette for breakfast, with cheese and onion and mushrooms, then salad with meat or fish at lunch, then for dinner I would substitute a pile of broccoli and cauliflower for the starchy carb the rest of the family had. The collins gem counting carbs book is very useful to look up which foods and drink are low carb. The new atkins diet book also has low carb meal ideas, which I found helpful. You sound quite slim, so I don't know why the Dr was putting the scarers on you.
