Fruit and lots of different kinds. I buy what's in season and small amounts of it, so it doesn't rot. I also buy frozen fruit of several varities.....Publix has great quality....peaches, strawberries, black cherries, blueberries, bananas, pineapple, cranberries, etc. I like to take out a few bags and make my own fruit cup with some different fruits. I let it thaw a bit and eat it as is. If the fruit is a little tart, I may add a dollop of low-cal Cool Whip.
I also have been slowly getting away from sweets, which has reduced the sweet tooth craving, along with the fruit snacking. I think my body is used to a different kind of sugar? I don't know.
I also like to snack on peanuts, in addition to fresh fruit and lite yogurt. Since we have started doing this, we just find ourselves eating less and buying less junk. It was a slow, deliberate change that has been very beneficial. Occasionally, we still buy ice cream or some chocolate, but they are savored in our new found moderation.
Another little change I've made is using dark greens for salad and lettuce. I won't eat iceberg lettuce anymore and prefer romaine or spinach. I substitute leaf spinach for lettuce on sandwiches and burgers and it has been no hardship or sacrifice at all. We haven't gone super healthy or calorie conscious here, but little changes made over time do add up. I don't do fad diets or pills and I hope trying to acquire new eating and exercising habits will result in healthy changes and sustainable results.
Also, I have been discovering that since I adopted a more active fitness routine of cardio, strength training and yoga, my appetite has changed. I crave less junk. Thanks to a DISer's tip, I bought a Polar heart monitor and I track calories burned during workouts, which makes things more efficient and helps me work smarter. All in all, I'm toner and stronger and the muscle gain is starting to burn the fat....no matter what I eat.
Good luck with your new habits and changes!
