Does Jenny Craig Work? It Sure Does. Here's How.

Jenny Craig basics

Before we dive into the details of how Jenny Craig works, it’s helpful to have an overview of the program.


1. You’ll eat Jenny Craig food — no cooking or counting required

With our complete plan, you’ll eat our ready-to-go breakfasts, lunches, dinners and two snacks each day (you’ll also enjoy one snack of your own). Most of the food is frozen, so make sure you have enough freezer space! You’ll also add your own non-starchy vegetables and fresh fruit to round out each day.


If you think Jenny Craig’s food is typical diet cuisine, don’t be fooled. Our premium meals are chef-crafted and big on flavor. The meals don’t just taste good, they’re also nourishing. Our meal plans are designed by registered dietitians to follow dietary guidelines, so you’ll get the nutrients you need while working toward your weight loss goals.


And don’t worry — you won’t be eating Jenny Craig food forever. Once you reach your weight loss goal, you’ll transition to our Maintenance Plan and begin making your own meals.




2. You’ll connect one-on-one with your weight loss coach

You’re never alone on your journey with Jenny Craig. You’ll connect weekly — over the phone or in-person — with your dedicated personal weight loss coach to discuss your goals, review your weekly plan and tackle any challenges. Your coach isn’t just a great resource, they’re also your number one cheerleader!


Having a weight loss accountability partner is one of the reasons why Jenny Craig works. Research indicates you could lose 3X more weight with support than dieting on your own!1



3. You’ll follow our science-backed plan

It’s no coincidence that millions of people have found success with the Jenny Craig program: Clinical research proves its effectiveness.2 A review published in the Annals of Internal Medicine found that Jenny Craig was one of the most effective commercial weight loss programs — and that it resulted in greater weight loss at 12 months compared to the control group.1


Jenny Craig isn’t a fad diet — it’s a weight loss program created by a team of medical and nutrition professionals. By following our plan and eating our balanced meals, you’ll learn how to lose weight and keep it off.


4. You'll focus on diet, not exercise.

With Jenny Craig, exercise is optional. Yes, you read that right: You don't have to work out on the Jenny Craig program. Our meal plans are designed to create a calorie deficit to help you lose weight without exercise. However, as part of a healthy lifestyle, we encourage you to try and meet the Centers for Disease Control and Prevention's recommendation of getting at least 30 minutes of moderate activity, five days a week and incorporating strength training exercises two days a week. But if you're an exercise newbie, don't fret. Focus on your diet first, and then you can slowly add exercise. Check out our Beginner's Guide to Exercise


5. You’ll lose weight at a healthy rate

While you might experience quick weight loss in your first few weeks, you can expect to lose 1-2 pounds a week on the Jenny Craig program. Although that might not seem like a lot, those pounds add up, fast! What’s more, experts agree that losing 1-2 pounds a week is not only healthy, but it’s also more sustainable.3

2. Select your plan.

Once you’ve connected with a Jenny Craig team member, you’ll choose which healthy meal plan is best for you. All of our plans include a variety of our nutrient-rich and delicious chef-crafted meals and snacks. Choose from:


Complete Weight Loss Plan: Rapid Results

This is our most popular plan that leverages the science of intermittent fasting to boost your weight loss potential. You could lose up to 16 lbs. in your first 4 weeks!†

† Avg. weight loss in studies was 11.6 lbs for those who completed the program.


With Rapid Results, you’ll nourish your body for 12 hours and then refrain from food and caloric beverages for the remaining 12 hours (this is when you sleep!). The program is designed to optimize your metabolism by eating when it’s most efficient and taking a break when you’re naturally winding down at night. Depending on how many calories a day you need to lose weight, your weight loss coach will set you up on our 1,200, 1,500, or 1,700 calories per day plan. 


Each plan has the perfect balance of macronutrients for weight loss: carbohydrates, proteins and fats. 


Type 2 Plan

This menu plan is designed to support people with Type 2 diabetes as well as prediabetes. In fact, clinical research shows our Type 2 plan may improve your glycemic control.4 Similar to our other plans it’s reduced-calorie, but it’s lower in carbs. This helps with glycemic control and weight loss.


Simple or Essential Meal Plan (online only)

These plans are built with your budget in mind. While they are not complete weight loss plans, they give you a taste of Jenny Craig’s delicious food and can help you save time during the week. Choose from a breakfast and lunch option or a full day of meals. Snacks and shakes are not included in this plan.

3. Meet your personal weight loss coach.

If you’ve selected our Complete Plan or Type 2 plan, you’ll set up a call with your weight loss coach to review your menu plan and discuss your goals. You’ll connect every week with your coach at a time that works best for you.


During your meeting, you’ll review your upcoming menu plan and discuss your progress. If you have questions about the program, need some advice or just want a little extra motivation, your coach will be there! Use this time to focus on you and your goals.



4. Get started and stay connected

Once your food arrives (or you’ve picked it up at your local center), it’s time to get started! Dive in to your delicious Jenny Craig food and stick to your plan for the best results.

5. Work toward your goals, reward yourself and modify as needed

Weight loss is a journey. But if there’s one thing for sure: It’s a rewarding one. As you work toward your goals, remember there will be highs and lows. Don’t forget to lean on your Jenny Craig coach during challenging times — whether you’re struggling with a weight loss plateau, an exercise rut or a stressful week. And know that you will succeed. Why? Because Jenny Craig works!


With every weight loss milestone you hit — reward yourself! It’s not just about reaching your goal weight — it’s about so much more. Losing just 5%-10% of your weight is a great place to start and an amazing accomplishment! You may also notice non-scale weight loss victories along the way, like fitting into your favorite pair of jeans, running around with your kids or feeling more energetic.


As you progress, work with your weight loss coach to modify as needed. Once you’ve reached your goal, you’ll transition off of our Complete menu plan and start making meals on your own. Your coach will guide you through this transitional phase to help you maintain your new weight and continue your newfound healthy habits.

The bottom line

So, does Jenny Craig work? We know it does! Are you ready to give it a try? From our balanced meals to our dedicated one-on-one support, you’ll have everything you need to take control of your weight and reach your goals.
