I would try gradually incorporating more healthful food choices and reducing the junk food. For example, instead of potato chips, opt for soy chips, or veggies and a hummus spread. Instead of refined sugar, opt for some fruit. I agree that when I make sure my intake of whole grains (brown rice, millet, rye, quinoa) is adequate, I don't feel any blood sugar imbalances which means I don't crave junky foods. Also, pick up a good macro cookbook (I like Christina Pirello) and start trying out the recipies. Some items may seem unusual (such as seaweeds, miso, ume vinegar, brown rice syrup, etc.) but they're worth adding to your pantry.

As for "urgent help", I'm not so sure that's possible in macrobiotics. I'm finding it's more about long-term, gradual lifestyle changes. Since I've been eating "mostly macro" (about 9 months now) I've noticed I crave different foods and don't even want the junk. I actually crave a nice dinner of steamed greens, grains, beans, and miso soup.

Good luck!
