Bottom line

If you can afford it, Jenny Craig is a proven and convenient weight-loss method. The program delivers prepackaged food to your home or office and provides support from counselors and fellow dieters. However, transitioning off packaged meals and to your own food is a challenge, and costs can be prohibitive.


Effective for weight loss. Experts and users agree that Jenny Craig is nutritionally sound and can lead to weight loss, but a review published on warns that the critical point comes when you transition from the prepackaged meals to preparing your own food. This diet is the star of a single clinical study published in a 2010 issue of the Journal of the American Medical Association. Researchers found that dieters lost significantly more on Jenny Craig than a "usual care" regimen, but critics say this is hardly a real-life scenario because the prepackaged meals and support were provided free of charge. There are no long-term studies on keeping the weight off, but consumer-reviewers indicate that it's easy to gain the weight back when you stop buying the food.

Key features

Your portions are controlled for you. Jenny Craig is structured around prepackaged frozen meals that restrict your fat and calorie intake; you purchase breakfast, lunch and dinner, then supplement meals with fresh produce and yogurt or purchased Jenny Craig snacks. All meals are delivered to your door on a weekly basis. Consumer-reviewers say the food is tasty, but the portions are skimpy. There is also an exercise component and plenty of support from Jenny Craig counselors and fellow dieters, as well as online. The diet is designed for your specific dietary needs, both physical and emotional. Experts and consumer-reviewers praise the level of support that's available.

Ease of use

No-hassle dieting. When you strictly follow the Jenny Craig plan, you know what you're going to have for every meal, every day. The meals come cooked and either frozen or packaged ready-to-eat. Just open a packet, heat it up, and eat. Some items don't even need to be heated. Calories are counted for you. Once you make it halfway to your goal weight, the amount of Jenny Craig food you eat diminishes and counselors begin helping you plan your own meals one to two days per week, which makes it less convenient.

Lifestyle factors

A pricey weight loss solution. The most popular component of Jenny Craig is its convenience, but you pay dearly for it. CBS MoneyWatch estimates a cost of $18 to $22 per day for three meals and two snacks and a total cost (including membership fees and meals) of $1,910 to lose 20 pounds over 13 weeks. Another source estimates a cost of $1,600 for 13 weeks. Users on Jenny Craig's forums say weekly food costs range from $90 to $170. It's not a viable option at some income levels, say experts. Others say for what you pay, you could hire a personal trainer and nutritionist.

Although the Jenny Craig participants lost more weight than the usual-care subjects, researchers say the high retention rate may be unrealistic once you factor in the program's high cost.
