I have lost 23lbs this year (and 31 from my all-time, non-pregnant high) and am just 14 pounds from my goal weight of 141lbs. I weight train regularly (2x a week for 45 minutes) and do 3 hours of cardio a week. I'm not sure what exactly to do about my diet, though. The weight is coming off so much slower now.
I eat:
B'fast: 1/2c. dry oats with 1c. water and 2 servings of fruit
(or one whole wheat english muffin with 1T spread + 2 fruits)
Mid-AM: 4oz of some protein (sometimes I forget this!) + some fat (nuts or avocado)
Lunch: 5oz of some protein, 1 carb, 1 fruit, 1 veggie
Mid-PM snack: some protein & 1 nonfat, plain organic yogurt (I never forget this!

)
5oz of some protein, 2 servings of veggies + 1/2c. of skim milk
I get really hungry in the evenings, so maybe I'm not eating enough during the day? This meal plan worked for me before, but it's getting harder to stick to and having less dramatic results.
