Alot of people use fruit juices as a substitute for sodas. It's better than soda, but it's true that it isn't the best; citrus juice from oranges and such may be better for some people.
I'm not focused on losing weight so much as sustaining. I exercise alot, but I'm really bad at eating healthy. While I hardly eat three square meals, I snack in order to sustain myself, but it's usually junk food or whole grain fruit bars. Any advice for healthy, portable snacks?
I can't stay off coffee or soda completely, either; it's the caffeine. I've got it down to a bottle of Coke and hardly a cup of coffee a day, but I still feel like it's too much. I think that over the holidays I'm really going to try cutting down to a bottle of soda a week…
Soda and fruit juice are best left to small portions. If you're really craving soda, drink half fruit juice, half carbonated water. It's fizzy, sweet, and will satisfy your sweet tooth in a way that High Fructose Corn Syrup never could. Unprocessed fruit sugars are able to be processed by the body properly, so they take the urge off your sugar cravings. For me, at least.
Generally, I always urge people to avoid HFCS. It's processed and awful.
