The Bernstein diet is a medically supervised weight loss program that requires a series of life changes. Besides the dietary requirements of the diet, you also need to make regular visits to a Bernstein clinic, take vitamins and supplements and practice behavior modification steps. According to an article in CBC News, followers of the diet must also get regular vitamin B complex injections.
How much protein you eat on this diet depends on the number of calories and the plan you're put on after your initial consultation. All three large meals of the day require protein, but you're usually free to choose what you prefer. According to Diet.com, acceptable options include seafood, fish and chicken. Vegetarian sources of protein include tofu, meat substitutes and soy products in general. Soy milk is often loaded with sugars so it's not allowed. Dairy products in general, however, are acceptable.
Fruits and Vegetables
Fruits and fruit juices are mostly prohibited to ensure you stay within the recommended carbohydrate intake, which is less than 30 g a day, according to Diabetes Explained. Non-starchy vegetables are acceptable. Examples of acceptable vegetables include asparagus, broccoli, mustard greens, okra, zucchini, mushrooms, pumpkin and scallions.
The Bernstein diet is a very low-calorie diet that shuns many carbs and most carb-rich fruits and vegetables, as well as drinks. In addition to water, club soda, herbal tea and decaf coffee are allowed. Artificial sweeteners are acceptable but not sugar or other natural sweeteners, such as honey. Herbs, caraway seeds and soy sauce can be used as seasonings.
