Isn't restrictive and encourages a balanced diet + moderation
Meticulous portioning can be complicated and time-consuming
For dieters who don't mind carefully prepping food
Prices for the books and food will vary
The Zone Diet was created by biochemist Barry Sears, PhD, and is based on his 15 years of experience researching bio-nutrition. Contrary to typical low-carbohydrate diets, Dr. Sears restricts daily calorie intake and emphasizes a strict diet ratio of 40:30:30, in which each meal should contain 40% carbs, 30% protein and 30% fat. He suggests that we think of food not as "a source of calories but as a control system for hormones." Dr. Sears blames obesity on cellular inflammation caused by a hormonal imbalance between the fat-storing insulin and glucagon (insulin's opposite). By eating the right food in the correct proportions, Dr. Sears believes we can correct this imbalance, and 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.
You can purchase A Week in the Zone on Amazon for $7.99, and you can also sign up as a member on their online community for free. To start, you will probably want to order the ZoneFast Program, which has two weeks worth of food for $180. After that, a week's supply of Zone 1-2-3 foods, like buns and pasta, costs about $75.
Product Report Card Grade
We give The Zone a B+ because it is an effective diet program that can make you look and feel great. While the program limits calorie intake, it doesn't restrict any foods and encourages dieters only to eat unhealthy foods in moderation. The Zone teaches about portion control and making healthy food choices from the beginning, so it is theoretically ideal for long-term weight loss and maintenance. Unlike some other diet programs, you shouldn't feel hungry on the Zone diet and your mind should feel clear and alert. That said, we had to deduct points when rating the Zone because it can be difficult to stick to the program's strict eating schedule and because it is also very time-consuming to accurately prepare/portion out your meals.
No foods are banned but some need to be eaten in moderation; if done correctly, you shouldn't feel hungry

Low-Calorie, Low-Fat, Balanced
Weight Loss and General Health
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 idea behind the Weight Watchers Program is that you'll eat less and won't feel as hungry if you make healthier food choices that fill you up for longer.
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.
How It Works
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.
Weight Watchers uses a PointsPlus system to help dieters measure daily food intake and to encourage them to make healthier choices. The PointsPlus system assigns a point value to different foods, which is calculated by its protein, carbohydrate, fat, fiber and calorie content, as well as by how difficult it is for the body to work it off. Each dieter is given a unique PointsPlus target according to their gender, height, weight and weight loss goals. You can basically eat whatever you want on the Weight Watchers program, as long as you stay within your daily PointsPlus target, but you are encouraged to eat more "Power Foods," which are considered the healthiest and most filling. "Power Foods" include whole grains, lean meats, low-fat dairy and (unlimited quantities of) fresh fruit and non-starchy veggies.
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.
Women will consume an average of 1100 calories a day, and men will consume an average of 1400 calories a day.
Since Weight Watchers uses the PointsPlus system, there isn't a focus on calories, but, no matter what, you will be getting at least 1200 calories a day.
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.
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.
You can sign up to attend group meetings at your local Weight Watchers branch or you can just sign up for the online program. To keep track of the points you are consuming, Weight Watchers also offers a pocket guide, pocket calculator, an online database of 40,000 foods and a mobile app with the database for additional convenience. Weight Watchers also offers recipes that show the PointsPlus value or, if you are making your own dish, you can use the company's online tools to calculate points ingredient by ingredient.
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.
While exercise is encouraged on the Zone Diet, it is not required.
Physical activity is encouraged, and Weight Watchers assigns different activities a PointsPlus value in order to incentivize dieters. Whether it is an hour of running, dancing or doing laundry, you'll receive extra food points when you exercise to allow for the occasional splurge.
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.).

Pros And Cons
- No foods are banned but some need to be eaten in moderation
- Meal plans take guesswork out of the diet
- If done correctly, you shouldn't feel hungry
- Complicated and scientific
- Meticulous portioning can be time consuming
- Limits calorie intake
- Expensive to follow
As with all weight-loss diets, you should check with your doctor or health care provider before starting on The Zone Diet, especially if you have any health conditions, such as diabetes or kidney disease. This diet doesn't get great online reviews despite its popularity. In a US News poll, The Zone ranked 17th in the "Best Diets Overall" category and only about 3.3% of dieters said the Zone worked for them. There's no scientific evidence that validates Dr. Sears claims, but that doesn't mean that his theories are necessarily wrong. If you have enough money to buy the pre-made meals, this could be a good plan for you, but otherwise it may be hard to follow on your own given the restricted calorie intake and importance of getting the proportions correct.
