Since she's just starting out, I believe she was still in Phase I and last time I checked, bread wasn't allowed and neither was the 100 calories for "extras." According to the SBD site, that starts in Phase 2. I believe she was having headaches during Phase I and was looking for a different plan to alleviate the headaches.
Phase 1: Following Phase 1 for two weeks kick-starts your weight loss. You'll eat normal-size portions of lean meat, fish, eggs, reduced-fat cheese, nonfat yogurt, nuts, and plenty of vegetables. Snacks and desserts are part of the plan, as well.
Phase 2: Next, you'll move on to Phase 2, where you'll learn to reintroduce the right carbs, such as whole grains and most fruits. Some indulgences are allowed. You should continue to lose weight on Phase 2 until you reach your goal.
Phase 3: Once you've reached your goal weight, you'll move to Phase 3 (the maintenance phase), where you'll continue to make good eating choices. The plan will feel less like a diet and more like a lifestyle.
I'm glad SBD is working well for you though! It's a very good plan and you're right, the cravings will go away.
