Welcome to Gaia! ::

I'm currently trying to do the same thing as you :3 Here's what I've been eating for about the past month:

Breakfast:
Any flavor Clif Bar (250)
Apple (50)

Lunch:
Low fat PB & J on Whole Grain Bread (240)
Special K Snack Bar (90)
1 cup of grapes (60)
3/4 cup of carrots (35)

Dinner:
Salad (lettuce both iceberg and romaine, carrots, 1/3 cup of cheese, two tbsp tortilla strip toppings, croutons, and 1 table spoon of reduced fat dressing) (270)
Chobani Greek Yogurt (100)
And about 150 calories of anything else that I want :3

and try to mostly drink water, and, just generally make good choices~

and for exercise, you can try doing ten or twenty minutes of yoga when you wake up and when you're going to bed. this lovely girl had made many many videos of super wonderful and relaxing beginner's yoga.

you'll see progress slowly. i know it might seem impossible considering you gained it back, but you will. you'll see it in the way that your pants get a little looser, and the way you can't grab your stomach quite so easily anymore.

i hope this helped and let us know your progress!!
