S.S.
Here are a few tips:
1) With soda I started by substituting it with club soda and fruit juice. Work up to a 1part juice to 3 parts club soda ratio or less. However, even if you use a lot of juice it is still a whole lot better for you that soda (especially diet) It isn't as sweet but it is the sodium you crave. Its a lot like an Italian Soda.
2) Try starting out small. We have meatless dinners about 3-4 times a week. Cheese raviolis with marinara sauce and a salad or veggie. Or baked potato night with options of cheddar cheese, sauteed onions & bell peppers, or broccoli.
3) My rule of thumb for meals it that at least half of my plate it filled with veggies or fruit.--salad, steamed veggies, fresh fruit, etc.
4) Here is the hard one (at least for me) eat small meals every 2-3 hours. It helps with your metabolism and you make better choices because you are not ravenous. My problem--I get so busy during the day that I eat mostly at night then I want dessert & snack after dinner.
Change is not easy and we all struggle with eating but making conscious choices to be healthy is a step in the right direction.
Hope this helps!
