The Promise

Some find it funny. Others think it’s offensive. Whatever your opinion of the title of fitness expert Jackie Warner’s book, it is definitely intriguing.

In This Is Why You’re Fat, the gym owner and TV personality says her plan will help you get “hot and healthy” without feeling deprived. Warner claims that by ditching sugar, caffeine, highly processed foods, fatty meats, and alcohol and replacing them with healthy foods, you’ll help correct your body chemistry, satisfy hunger, and reduce cravings.

What You Can Eat

Despite its harsh-sounding title, the booktakes a moderate approach to weight loss, promoting what's often called "clean eating," or eating foods as close to their natural state as possible.

You spend the first 2 weeks in the "jump start” phase. During that time, you won’t eliminate anything from your diet. Instead, you help your body get in “fat-burning mode” by adding certain foods including two eggs, 1 cup of oatmeal, 2 to 3 cups of vegetables, whey protein shakes, and lots of lemon water and herbal tea.

In the diet's second phase, which you can stay on forever, you eat minimally processed or unprocessed healthy foods Monday through Friday as well as most of Saturday and Sunday, and enjoy two treat meals of your choice on weekends -- they shouldn't exceed 1,500 calories.

You eat lean protein (like turkey breasts, eggs, and beans) at every meal. You’ll also eat at least 2 cups of vegetables daily, as well as two pieces of fruit, two servings of whole grains, and small amounts of plant-based fats like safflower oil.

Warner recommends avoiding white flour, sugar, and artificial sweeteners; minimizing caffeine; and avoiding alcohol 5 days a week, due to the calories in alcohol.
