What You Can Eat and What You Can't
You need to cut all meat, dairy, eggs, and fish. You'll also need to shun sugar, artificial sweeteners, and refined carbs.
Caffeine and alcohol are strongly discouraged. But an occasional cup of coffee or glass of organic sulfite-free red wine is allowed. They also ask you to eat only organic.
The ideal Skinny Bitchbreakfast is fruit. Lunch is a salad and/or vegetables. Dinner is something "heavier," such as a fake chicken patty or tofu stir-fry.
Level of Effort: High
Unless you're already a vegetarian, be prepared for a major lifestyle overhaul. Even the authors acknowledge that adapting to their regimen may leave you feeling "deprived, angry, overwhelmed, and frustrated," especially for the first few months.
Limitations: You'll need to kiss your carnivorous ways good-bye.
Cooking and shopping: You may also need to find a new grocery store. Your regular shop might not stock certain recommended items. Dining out may be difficult. Many of the foods you'll eat require prep work of chopping (think whole fruit and raw veggie salads).
In-person meetings: No.
Does It Allow for Dietary Restrictions or Preferences?
There's some wiggle room. For example, while Skinny Bitch recommends a fruit-only breakfast, it also includes a list of acceptable packaged breakfast items.
What Else You Should Know
Costs: The net cost of embracing the Skinny Bitch diet should be minimal. You'll probably pay more for organic produce and many organic/vegan packaged products. But you'll no longer be shelling out for costly meat, poultry, and fish.
Support: This is a diet you do on your own.
