Hee, hee! I love Mamasource, too!
I'm not a dietician or anything, but I can tell you my experience. When I got pregnant with my son I got gestational diabetes (and it didn't go away after he was born so I'm diabetic now). I was thin to start out with and gained 45 pounds during the pregnancy. He was born at 7 lbs. 15 oz. I continued the diabetic diet and weigh less now than I did when I first got pregnant.
To me, a diabetic diet is "healthy eating," although I had to be diabetic to force myself to eat this way. So I wish you luck and great willpower.
I was taught to count carbohydrates to control my blood sugar. Carbs seem to be the culprit in weight gain. Almost everything you eat is converted to a form of sugar your body can use for energy. For the purposes of a diabetic diet, everything except meats and most vegetables are considered a carbohydrate. In other words, when you are hungry, fill up on meat and vegetables.
Of course you need the carbs, too. You just have to limit them. Since you're not diabetic, you have all kinds of leeway, but I'll describe how my diet was set up.
1)Eat often, but eat smaller portions. If you eat regularly throughout the day, you won't be as hungry and won't eat as much at mealtimes. Believe me. And small meals means you don't get hungry and that = less morning sickness. Even though you are eating more often, don't sit down to a meal. A snack is something like an apple and a handful of nuts.
2) Limit your carb intake. A snack is 15 carbs paired with protein (an apple and a handful of nuts). I needed the protein to regulate the blood sugar rise caused by the carb, but I suggest it to you anyway. I was told that I was the only one in the maternity ward without anemia. A meal is 30-45 carbs (remember your protein).
a) 15 carbs is like 1 small or medium apple, one small orange, a half banana, 1.25 cups of watermelon, one pear, 2 apricots, a handful of berries, one piece of bread, 1.5 sheets of graham cracker, etc. I think there are lists you can find online and in nutritional books giving more examples. I got one from a Kaiser health fair. One cup of milk is almost 15 carbs!
b) When you have to follow this diet you realize that you have little room for unhealthy eating choices. "Hm, do I want to eat an apple which will fill me up better than 1 single cookie, which will leave me starving for the next two hours?" The apple always wins.
c) Because I was diabetic, I was limited to eating a snack every two hours between meals. That doesn't sound bad, but I was STARVING. I was not allowed to graze. I mention these points because I think you can refer to them as a non-diabetic person regarding weight gain. For example, to avoid gaining weight, eat a small snack every two hours or so and choose healthy foods. Don't mindlessly graze, especially on empty calories like chips, cookies, etc.
3)LEARN TO READ NUTRITION LABELS!!!!!!!!! I can not emphasize this enough. Every packaged food has a nutrition label on it in the US. All you have to do is read "Total Carbohydrate" and find the serving size. The amount of sugars, fiber, etc. doesn't matter (listed under total carbohydrate). This is what my doctor told me for the purposes of being gestationally diabetic. There are finer points to this that I won't discuss right now. If "Total Carbohydrate" says 15 g or less, eat the serving size for a snack. If it's more, avoid it or eat it for a meal when you are allowed more carb intake.
a) This is a really important concept!! Don't forget to look at the serving size. Just because something says 15 carbs doesn't mean it's OK to munch. The serving size might be tiny. If you eat the serving size, you go hungry. If you eat more, you gain weight. For example, I've seen cookies that were 20 g. I thought that wasn't so bad. Then I noticed that was for ONE SMALL COOKIE.
4)Keep in mind that drinks can be a significant source of carbs. I wouldn't suggest to you to stop drinking milk even though it has a lot of carbs, although I have pretty much stopped drinking it (as much as I love it :-( Be aware of soda intake, smoothies, flavoured drinks, icees, etc. If you can't live without flavoured drinks, try to find sugar-free 0 carb drink mixes. I drink water and that's pretty much all I drink. (I avoid caffeine in tea and coffee.)
5) DO NOT DEPRIVE YOURSELF. You can be "good" for only so long. Then you binge and undo it all. Have a treat!! I count out my carbs all day and then indulge in a cup of ice-cream. That's the thing I can't live without :-D This is where you have room to maneuver in your diet since you aren't diabetic. Geez, you could even have the fudge topping, whipped cream, and cherries on top!
6) This is a helpful hint. Shop around the edges of the grocery store. I've found that's where the staples like fruit, vegetables, bread, and meats are. The inside aisles are usually filled a billion and one variations on carbohydrates wrapped in pretty packaging that make you want to eat it really bad. I don't even walk down the middle aisles if I don't have to. The temptation is staggering.
7) Another helpful hint. You might want to compile a binder of "healthy" recipes of food you enjoy. It's something to turn to when you are feeling hungry, tired, and uncreative and it's easier to grab carb-laden food. Carbs are so easy and so cheap to get compared to good food. Also, you can turn to it after the baby is born. Healthy eating is a lifestyle. Once you get the hang of it, it's not bad. Why stop?
a) I was required to keep a food journal. I wrote down everything I ate and drank (including serving sizes). This might help you. First, it makes you aware of what you are eating and how much. Second, you might identify patterns in your eating habits. Third, it's helpful when you think you'll throw up if you eat another graham cracker with peanut butter again, but you just can't think of anything else to eat. You look back on your food journal and remember, "Oh my God, I love strawberries and cottage cheese! I'm going shopping!"
8) Because you are pregnant, DRINK 64 OUNCES OF WATER EVERY DAY! That's a lot of water to me and one reason why I drink only water. I don't have room for other drinks if I'm to meet that goal :-D Seriously, the fetus needs it and it's great for your body.
9) You're pregnant. Take a break. Get some sleep. The less sleep you get, the more you eat. Well, at least I do. If you are well-rested, you'll feel less hungry in general. Hey, and if you are sleeping, you can't be eating at the same time ;-D I used to be a night owl.
A sidenote on protein. I hate meat and tofu. I've found that some good protein sources are cottage cheese, cheese, yogurt (but that has too many carbs for me), peanut butter, and nuts. Beans are considered a carbohydrate.
Well, I hope this isn't too long or overwhelming. I tried to simplify it. I've been eating like this for about 2.5 years now. I have to admit, I feel way better than I ever have in my whole life previously.
I don't know of pregnancy exercises, but exercise is SO important to managing diabetes. I'm not into exercise all that much. So what I do is walk. I take a walk after lunch and a walk after dinner. I try to walk at least 15 minutes twice a day. If I don't have time, then I do more strenuous exercise like running or jumping around like a crazy person -- whatever makes me sweat.
I'm not sure about if you should carry your son or not. I guess it would depend upon how you feel. I felt fine throughout most of my pregnancy with my son, but I noticed that toward the 7th month it just HURT to pick anything up! My belly would cramp up and leave me breathless. At that point I quit trying to pick up heavy things.
It sounds like you guys are creating a beautiful family. Congratulations on your pregnancy! I wish you the best.
