I'm not familiar with Sugar Busters WOE. If you are looking for a healthy plan that is similar to South Beach check out the Sonoma Diet. It is very similar to So. Beach but the induction phase (called Wave I) includes grains. It also helps with portion control issues, too. You can have 2 servings of grains per day on Wave I. This was a bit much for me so I limit my grains to no more than once a day, sometimes none at all.
Check it out. You might find a happy medium between the two plans. Both are based upon healthy fats and grains, with Sonoma leaning towards the Mediterrean way of eating.
