I'm diabetic and there is a great site called CalorieKing.com . You can look up just about an food, including veggies and fruit and find out the nutritional intake including carbs/sugar which I'm assuming is what you're paying most attention to.
As for cravings. You can do sugar free candies, just not a lot. They're high in calories and can give you diarrhea. Other than that I find either fruit works, or a can of diet soda. Oh and a good treat is sugar free popsicles. They have hardly any carbs (4), 15 calories and no sugar.
Also. Something really good to eat to keep your sugar regular. FiberOne makes those Antioxidant Plus bars. I can eat the Chocolate Chip or Peanut Butter one for a snack and there aren't too many carbs or sugars (I can't remember off hand). They also make really good cereals but you have to watch the serving because the sugar adds quick. Popcorn plain airpopped if possible is also good for you (watch the carbs). You can even do the 100 calorie snack bags and a huge glass of water and it'll help fill you up.
When I started taking Metformin I lost 50lbs. I have a hard time with depression and my husband is in the army and always gone. And Im an emotional eater. But I find it easier to lose weight on Metformin. I've been staying steady currently because I haven't been eating like I'm supposed to. But I also find that I can exceed the recommended carb count a bit without it affecting my sugar. I don't nessicarily recommend that but for me it doesn't bother me. But usually when I do it's something full of fiber which is a diabetics best friend.
I hope that helps you a little bit. You can always send me a message if you have any questions
And I'll tell you what the doctor told me. If you're eating broccoli, cauliflower, etc you can eat as much as you want. So use CalorieKing.com and look up your favorite fruits and veggies and if they're low carb you can eat more of them. It'll help you feel full longer eating more veggies than anything else.
And by the way, you look good. You can definitely tell a difference with the 24lbs. You're doing good! Obviously I didn't read the entire thread before I wrote this but.. haha. Congrats on the baby!
