American culture is more critically aware of health, nutrition, and weight loss than it has been in recent years – for good reason. Today, children, teens, and adults all suffer from an increase in asthma, allergies, diabetes, obesity, fatigue, weakness, vitamin deficiencies, and other serious health and medical illnesses. You can hardly read a newspaper or do an internet search without coming across the latest problems, trends, and quick fixes. For as many weight issues out there, there are almost as many solutions.
So, where does that leave you? Maybe you want to learn more about diets in general. Maybe you are looking to actually lose weight. Maybe you have tried some programs with no success. No matter what your diet/weight loss program interest is, if you are looking into a diet program, there are several established, research-backed, successful weight loss programs to choose from. The trouble comes when you don’t know which one will be the best one for you?
There are essentially six factors of any diet plan that you want to examine before you begin:
- Options & What’s Included – Is there a plan tailored for you based on gender, age, or illness? Are there extras and do they cost more?
- Effectiveness – Is there research backing the plan? Has is worked for others? How quickly does it work?
- Diet/Nutritional Information – What is the actual nutritional value of the food you will be eating (or not eating)? Is it healthy?
- Availability & Delivery –Do you have online access? Is there a center near you? How do you get the food?
- Cost – Can you afford it?
- Support – Is there a community or are you going it alone?
The following provides a detailed overview of four of the most popular diet weight loss programs available today. NutriSystem, Weight Watchers, Medifast, and Jenny Craig are all at the forefront of the dieting world. “The Basics†will give you a look at a specific program – so you can check out the plans that you are most interested in. “The Bottom Line†offers a side by side comparison.

NutriSystem: The Basics
NutriSystem is a weight loss diet plan that focuses on convenient weight loss. Prepackaged meals are shipped to your home and you simply warm them up and eat them. No counting, measuring, or even cooking. While you need to supplement this diet with fresh fruits, vegetables, and dairy products this is a very convenient plan. The foods you must buy are straightforward and simple choices.
- Average cost per month without fresh foods: approx $295.00
- Average cost with fresh foods: approx $495.00
- There are NO additional costs
- Very effective
- Very fast
- Most food is processed
- Some say that it is the best tasting prepackaged diet meal plan available
Nutritional Information
The NutriSystem diet is based around something called “the glycemic index.†Simply put, this is an index that indicates how quickly your body breaks down carbohydrates into sugars. The thinking is that a high glycemic index results in a faster increase in blood sugar levels – resulting in increased fat conversion. The diet, therefore, focuses on foods with a low glycemic index. The nutritional ratio of the foods provided is 55% carbohydrates (low GI cards), 25% protein, and 20% fats. The average daily calorie intake is between 1200-1500 calories over 3 meals and two snacks.

Weight Watchers: The Basics

Weight Watchers focuses mostly on portion control and moderation. There are no food supplements, although you can buy prepackaged meals if you choose to. Each food is given a point amount, and each person is given an amount of points per day to eat. If you stay within your points, you will lose weight.
- Cost per month: approx $700.00
- Cost per month online: approx $685.00
- Any extras (dining out guides) do cost extra
- There are “Flex Points†which are extra points during the day based on exercise, etc.
- You keep a daily log of what you eat to keep track
- Focuses on healthy eating habits
- Education on how to eat what you like in a sensible way
- There are “core foods†that have given points and can make up simple meals to avoid scoring other foods
- An effective weight loss program – average weight loss is typical ½ to 2 pounds per week
- Many feel this has better long-term results as you eat your “regular†foods throughout
- Meetings, in person or online, are part of the program for weight loss and dieting support
- These are considered an essential part of this plan
- Weigh-ins, tips, tools, support, guidance
Nutritional Information
This is a tricky one. The nutritional value of this program is what YOU put into it. If you are allotted between 31-35 points per day (the average), and you choose to eat small amounts of junk food instead of larger amounts of healthy food, in theory, you can. This is not the point of the plan, obviously, but the point here is that the healthy nutritional content of this diet is dependant on the dieter’s education and knowledge of healthy food chooses – which may be questionable as that is how he or she ended up needing the diet in the first place. Points are determined on a number of factors – portion size, calories, and the amount of fat and fiber in serving.
Weight Watchers Plan Options
Since the plan is designed around the food that you eat, it can be tailored to any personal plan. Weight Watchers offers points systems for the following groups.
- Men & Women
- Vegetarians
- Older Dieters
- Diabetics
- Pregnant and Nursing Moms
- Targeted Event Plans – example: brides
A Typical Weight Watchers Meal
3 oz. grilled chicken breast...3 points
½ cup rice......2 points
1 cup fresh pineapple... 1 point
2 cups mixed greens... 0 points
2 tablespoons reduced fat dressing 2 points
Total...8 points
Possible Cons/Drawbacks to Weight Watchers:
- Weigh-ins can be very public for some people, privacy is not always realistic at meetings
- There is a lot of counting with this program which is annoying or tedious for some
- Some have reported that the hyper-vigilance with counting, points, and journaling has led to an obsessive-like relationship with food
- The extras cost extra
MediFast: The Basics
Medifast is exactly what it sounds like. It is a medically guided fasting diet. You do not actually fast, but the majority of the diet is liquid – which is considered a fasting diet.
- Cost approx $315.00

- Lean = 5-7 ounces lean meat
- Green = 3 servings from supplied veggie list
- You eat every 2-3 hours
- No calorie counting
Nutritional Information
The nutritional content of the food in this program is pretty astounding. Medifast considers itself a medical diet program, so the nutritional content is very good.

Jenny Craig: The Basics
Jenny Craig is a weight loss dieting program that is similar to NutriSystem in some ways. Prepackages, prepared food is provided. The plan is easy and simple to follow – you simply eat the given meals you are allowed in a day. However, there is also a very personalized element to Jenny Craig. The cost is higher, but the program is more tailored to you specifically – not just your weight.
- Cost per month: approx $815.00
- Complete personal, health, and lifestyle profile done in the beginning
- Fitness program and recommendations are included
- Goals, progress, milestones, and successes are recorded and examined
- Lots of personal support and consultation
- Incorporates grocery foods with planned meals
- Proven to be very effective
- Focus on weight loss and maintenance
Nutritional Information
As with NutriSystem, the food is prepackaged so there is a much higher sodium content to them. Food is designed for low-fat, low-calorie, high fiber, and high protein. You also must supplement with fresh fruits and vegetables, whole grains, and “heart healthy†fats – this is very important for healthy vitamin and mineral maintenance.
Jenny Craig Plan Options - In-Centre, Men, Type 2 (For diabetics), At Home, Silver, Teens

Possible Cons/Drawbacks to Jenny Craig (similar to NutriSystem)
- Boredom with food – repetition
- Taste – very subjective; some people really like it; others don’t
- You do need to purchase additional food
- Complete Meal Replacement Diets make transitioning back to regular diet & food difficult
- Not good if you do not like processed foods
- Not good if you are concerned about increased sodium
- Cost
The Bottom Line Comparison
Diet
- NutriSystem: Average calorie intake between 1200-1500 calories. 3 meals and 2 snacks are designed to be high fiber, high GI carbohydrates, low sugar, and moderate protein. Vitamin and mineral content is fair – supplemental whole grains, healthy fats, and fruits and vegetables are essential.
- Weight Watchers: You may eat what you like within your points – this can lead to a continuation of poor or unhealthy eating habits – just limiting them. Of course, the program does promote eating whole grains, lean proteins, fruits and vegetables, and dairy. Exact calorie count is not known.
- Jenny Craig: Average daily calorie intake is 1300 across three meals and one snack. Food is high fiber, high protein, low fat, and low calorie. Vitamin and mineral content is fair – supplemental whole grains, healthy fats, and fruits and vegetables are essential.
- Medifast: Average calorie intake is between 800-1000 calories. Vitamin and mineral content is excellent.
Effectiveness
All programs are very successful. If you stick with any of these plans, you will lose weight. They also all work fairly quickly. Medifast and NutriSystem tend to work faster as there are fewer daily calories. Any added fitness and exercise program increases weight loss and speeds up weight loss time.
Long-Term Effectiveness
This is subjective because the long-term effectiveness depends on an individual’s ability to continue to practice what they learned – in moderation for weight maintenance. Complete meal replacement programs can be harder to transition from back to “regular†eating. To maintain your weight loss, you must be able to eat “grocery store foods†in moderation. A program like Medifast doesn’t do this.
Cost
They all involve an investment – some more than your typical, current grocery bill. NutriSystem is the least expensive, followed by Medifast. Weight Watchers costs less than Jenny Craig, but both can average almost double the cost of the full meal replacement packages. Cost analysis takes into account additional food costs – the extras that are not included in other plans make these programs more expensive – even with additional food.
- NutriSystem $295.00 (without additional food)
- Medifast $315.00 (without additional food)
- Weight Watchers $700.00
- Jenny Craig $815.00
Delivery
NutriSystem, Medifast, and Jenny Craig can all be delivered to your home. Weight Watchers cannot.
Personal Support
All programs involve support networks. NutriSystem’s and Medifast’s support is entirely online. Weight Watchers and Jenny Craig all offer in person or online support.
Fitness
Jenny Craig is the only plan where you get a personalized fitness program as part of your package. The others do not; they offer information. NutriSystem offers exercise DVDs with certain plans. Medifast includes a 26 page exercise and fitness guide. Weight Watchers Online provides exercise and fitness information.
Online Availability
All plans offer online options, support, planning, ordering, and information.
