Breastfeeding, food combinations, and calorie counting.
I ate the weight I wanted to be times 10 in calories... so:
I wanted to be 120 lbs...
120 X 10 = 1200 calories
plus I breastfed so I allotted an extra 300 calories for that:
1200 + 300 = 1500 calories
If I exercised I looked up "calories burned" for that activity and added some extra calories to my daily intake based on that. I reached my goal weight when my daughter was 9 months. my goal weight was actually 25 lbs LOWER than my pre-pregnancy weight.
For every meal I combined 1 protein source, 1-2 carbs (15 grams of carbs per serving), and 1 or 2 fruit or vegetable servings... I ate three meals and 1 or 2 snacks every day- with the occasional "dessert" after dinner on days I could afford it (calorie budget wise) When my daughter started eating solids I made my own baby food- and ate a lot of the same foods I made for her LOL!
By losing that weight and making changes in my diet habits, I was lucky enough to avoid gestational diabetes in my current pregnancy! (I had it in my first!) woohoo- double bonus! So- know that the benefits are really truly well worth getting back to a healthy weight!
By the way- once I reached my goal weight I SLOWLY upped my calorie intake until I reached a place where I no longer would lose weight, but wasn't gaining any either- for me that was at about 1700 calories or so. Eventually I stopped counting calories and just tried to maintain roughly the same eating habits while watching the scale at least once a week.
That said- we had a few stressful months and I gained about 8lbs right before I got pregnant this time... I knew it was happening and was jumping back on the diet train when I found out i was pregnant, haha! - If you do start gaining weight again, just don't wait until it becomes more than you can handle...
to count calories.. you may want to get a food scale and some measuring cups and spoons until you are used to "eyeing" the right portions. Then use a site or a book to look up any foods that don't have nutrition facts ON them (like fruits and veggies) I used the sparkpeople website and I LOVED it!
Good Luck!
