The idea behind the Jenny Craig program is that you can lose weight and maintain that weight loss when you combine balanced nutrition and portion control with an improved attitude toward food and exercise.

The Zone Diet promotes the idea of food not as "a source of calories but as a control system for hormones." By eating the right food in the correct proportions, the body will reach a metabolic state where it is operating at "peak efficiency". You not only lose weight, but you feel great, mentally and physically.

The Jenny Craig program assigns each dieter a personal Jenny consultant who will customize their weight loss plan and meet with them during weekly one-on-one sessions to help guide them through the program's 3 stages - food, body and mind. To educate you on nutrition and portion control, the program initially provides frozen or shelf-stable prepackaged meals that are high in fiber and low in fat/cholesterol. You will supplement these meals with 2-3 servings of fresh fruits, vegetables, or non-fat dairy products bought at a local grocery store. Halfway from your goal weight, you will slowly transition to cooking your own meals (using Jenny recipes) until you have reached your goal weight and are only cooking your own food. Meanwhile, your Jenny consultant will help devise a workout program based on your current activity level with the ultimate goal eventually being 60 minutes of advanced physical activity a day (Pilates, running or weight training). Your Jenny consultant will also help you better understand how your existing relationship with food, life experiences and social environment have impacted your health and weight, and how you can build the necessary skills to change your previous mind-set and maintain the good habits that you have acquired during the program.

Created by biochemist Dr. Barry Sears, the Zone Diet controls dieters' food intake using a "food block" system, which assigns values to different foods. For example, 1 food block could equal 12 spears of asparagus or 1 ounce of chicken or 1/3 teaspoon of olive oil. Most women are able to consume 11 food blocks a day, while most men will be allowed 14. Eating in the right proportions is also essential on the Zone Diet. Each meal should be 40% carbs, 30% protein (low-fat), and 30% of healthy fat. When putting together your plate, 1/3 of it should be filled with a low-fat protein (3 oz for women or 4 oz for men), and the other 2/3 of it should be filled with low-GI carbs (ex. vegetables, lentils, beans, whole grains or fruit). You can then use a "dash" of heart-healthy monounsaturated fat (ex. olive oil, canola oil, macadamia nuts, and avocados) on top. Finally, the Zone requires keeping a food journal where you track what you ate and how you felt after 4 hours. If you aren't hungry and your mind is clear, your body is in The Zone.

Calorie intake can range from 1,200 - 2,300 calories per day depending on the plan you come up with your Jenny consultant, which will be based on your age, height, current weight, gender, your activity level, etc.

Women will consume an average of 1100 calories a day, and men will consume an average of 1400 calories a day.

You can participate in the program by attending weekly sessions at a local Jenny Craig center or you can also participate from the comfort of your own home. Either way, you will have access to a Jenny consultant for one-on-one weekly meetings and to Jenny's 24/7 telephone line to get information or support whenever you need it. The program also offers online support, including peer-support discussion groups and progress tracking tools.

The Zone Diet sells how-to books with different recipes to try and also offers free access to their online community, which includes message boards, recipes, meal planners, body fat calculators, etc.

30 - 60 minutes of physical activity is encouraged, and your Jenny consultant will help you determine your fitness goals/routine. Usually, Jenny consultants will try to incorporate exercise into your daily life (ex. walking, taking the stairs, doing laundry, etc.), but they may suggest that already active dieters add more rigorous exercise (ex. Pilates, weight training, etc.).

While exercise is encouraged on the Zone Diet, it is not required.
