I was around the same starting weight and height as you. I aim for between 1400-1800 cals a day and still lose around 1 sometimes 2 lbs a week. I figured out my calorie needs by going to
http://www.freedieting.com/tools/calorie_calculator.htm To figure out my BMR
I'm low with my calories frequently, but when you're eating lots of whole foods, it's hard to eat enough!
These are things I pick from on most days--
bfast:
I eat lots of eggs (whole eggs, yolk included)
Bacon
only 100% whole wheat bread (at least 3 grams fiber per serving)
Kashi Go Lean Crunch Cereal
Steel Oats with fresh blueberries and strawberries, walnuts & flaxeed
Greek Oatmeal with berries
Lunch:
turkey sandwich with tomatoes, & spinach
Big salad with romaine lettuce and spinach, cottage cheese, veggies(tomatoes, cucumbers etc), & turkey slices
Dinner
lean protein (chicken or fish)
lots of veggies
I still eat things like spaghetti, but do a bigger portion of veggies and only eat whole wheat noodles. I sub spaghetti squash a lot
Chili made with chicken & dried beans
Anything I used to eat but in smaller portions & I add more veggies
Snacks=Broccoli, hummus, fruits, veggies, yogurt, nuts (almonds, walnuts), craisins.
I also drink unsweet tea & water throughout the day
I exercise about 5 times a week.I do everything from Pilates, Yoga, swimming, cardio, circuit training, interval jogging etc
*try to eat lots of protein and fiber. It will fill you up.
I may not be losing weight the fastest ever, but it is something I can sustain forever. The weight is coming off slowly,but I will get there eventually. My body is changing like crazy and I'm enjoying it and loving the extra energy and I feel great!
ETA: So some people may believe that 1200 is not enough, but if you're eating truly healthy whole foods, feel satisfied and have energy, I think it can totally work. In fact I certainly think it's far better than eating the zillions of calories of almost no nutrient junk many people eat every day (like I used to)
