What is the 400 Calorie Fix Diet

The 400 Calorie Fix is a diet plan created by Liz Vaccariello of Prevention Magazine. The main concept of the plan is that you have 3 or 4 meals each day, each of which is 400 calories. On this plan, you can still have any of your favorite foods as long as each meal is less than 400 calories. The book includes tips and recipes for eating at home, dining out and even eating at fast food restaurants.

How the 400 Calorie Fix Diet Works

The 400 Calorie Fix encourages foods that have monounsaturated fats, like avocado, olives and nuts, as they will reduce your cravings later in the day. It also emphasizes high protein foods for similar reasons as they stimulate neurotransmitters and hormones that will make you feel fuller. The recipes in the book are divided into four groups, each of which contains a different main nutrient (protein, monounsaturated fatty acids, fiber, fruits and vegetables) with the goal being to eat one meal from each category every day in order to meet your basic nutritional requirements. There is also a 2-Week Quick Slim diet to get faster results in which you have only 3 of the 400 calorie meals each day and exercise as well.
