Lisa,
I'll give you the run down of my typical week exercise and nutrition-wise.
Monday, Wednesday, and Friday - lap swimming for 35 minutes at 5:30 am, 30 minute walk around 12:30 pm, 35 minute walk with the dogs 4:30 pm, 60 minute zumba (all except Friday) 6 pm
Tuesday/Thursday - 30 minute walk 12:30 pm, 45 minute walk with the dogs 4:30 pm, 3-5 mile run 6 pm, 45 minute video - either kickboxing or some other cardio
Saturday - 60 minute boot camp 9 am, 60 minute walk with the dogs (sometimes longer)
Sunday - 60 minute walk with the dogs, run and/or video
As far as my diet goes, it's pretty monotonous, especially during the work-week. It generally looks like this:
Breakfast 10 am - fat free plan greek yogurt with .33 serving of Protein powder mixed in (146 calories, 26.6 g protein)
Snack 1 pm - Protein shake (30 grams protein, 160 calories)
lunch 3:30 pm - 1 hard boiled egg, 1/4 cup low fat cottage cheese, 2 oz raw veggie (cauliflower, broccoli, or carrots) (about 132 calories, about 14.4 g protein)
Snack - 6ish pm - protein shake and one serving PB2 (115 calories, 18 g. protein)
dinner - 8 pm - large salad with either tuna, salmon, edamame, bun-less veggie burger, or tofu - salad includes 3 oz romaine lettuce, 0.3 oz alfalfa sprouts, 2 oz broccoli, 2 oz cauliflower, 2 oz mushrooms, 1 oz celery, 1 oz green or red pepper, 1 oz carrots, 1/2 tablespoon greek dressing - 88 calories for salad without protein, protein ranges from 60-100 calories. Lately I've added in a small amount of fruit - 4 oz peach, 1 small plum, 4 oz mango, 6 oz apple, or a large tomato.
I take one chewable multi-vitamin per day, 1200 calcium - one at breakfast, one at dinner, 2 times a week, I take a B12, and 2-3 times a week, I take 1000mg D3. (my multi-vitamin and calcium are an extra 30 calories per day)
I just had my blood taken last Saturday in preparation for my year appt on the 20th. I'll know better then how my Vitamin levels look, but I'm really strict with taking my Vitamins. Eventually, when I'm in maintenance, I'd like to up my calorie intake to somewhere between 1000-1200 per day, but for right now, I'm sticking with the range I've been eating.
I hope that helps!
