Rapid Results™ FAQs - Your Questions, Answered!

By Jenny Craig

Whether you have already signed up or are thinking about starting Jenny Craig’s new Rapid ResultsTM program, you probably have some questions.  We tapped Janet Nash, RD from our team to help answer those FAQs. She shares the “how” and the “why” behind Jenny Craig’s new program, which leverages Nobel Prize-winning science involving the body clock’s circadian rhythm, to help accelerate weight loss.

What is the Rapid Results program?

It is an innovative science-based program that leverages the body clock’s natural circadian rhythm to help optimize metabolism and accelerate weight loss.


Recent studies have shown that each cell of our body contains biological clocks that follow a unique daily 24-hour cycle, called a circadian rhythm.  The 2017 Nobel Prize in Physiology or Medicine was recently awarded to three American scientists who discovered the circadian rhythm gene.  From this research, we have learned that our internal network of body clocks dictates when to sleep, awaken and eat.  The Rapid Results program was designed with this science in mind, taking advantage of our natural metabolism and ability to burn calories when it’s most effective.  Members who completed the Rapid Results program lost up to 16 pounds in the first four weeks. The average weight loss in the study was 11.6 pounds for those who completed the program.


Who can participate in the Rapid Results program?

You can sign up for Rapid Results if you are 18 years and older.  If you are pregnant, breastfeeding, or have diabetes, then Rapid Results is not right for you.  Adolescents and mothers who are breastfeeding may do the Jenny Craig Classic Program.  Those with diabetes can sign up with the Jenny Craig Type 2 Program.

How Does Rapid Results work?

The Rapid Results program incorporates our 24-hour biological clock that is in sync with daylight and darkness.  Every system in the body has its own unique clock and the digestive system is no different – all the processes of digestion, absorption and metabolism of food are well orchestrated and they do their job best during the daytime.  But at night when the sun is down and while we are sleeping, this system is tasked with other vital functions – repairing and regenerating from a long day’s work.  When we eat in accordance with our natural clock, we harness the best results in weight loss.  In addition to improved weight loss and appetite control, research also demonstrates other benefits to following this natural daily cycle, including increased belly fat loss and improvements in immune and mental functions. 1-6

How Is Rapid Results different from the Classic Jenny Craig program?

The Jenny Craig plan is known for and has been praised by weight loss experts for its commitment to providing perfect-portioned, balanced and delicious menus with the support of a weight loss consultant to address the what and the how much to eat.  Now, Rapid Results incorporates when to eat.  A rejuvenation break has been integrated into the program based on research that demonstrates the numerous health benefits of allowing your body to regroup and regenerate after a busy day of metabolizing your food. Here’s the breakdown:


Rapid Results divides the day into two segments, a nourishment period and a rejuvenation period. During the nourishment period, members eat six times and choose from chef-crafted and nutritionist-designed meals. There is no counting, cooking, or meal prep and the daily menu is based upon appropriate nutrition for healthy weight loss. Throughout the nourishment period, Rapid Results provides more calories when your metabolism is burning the most calories.


The rejuvenation break plays a critical role in the weight-loss plan as a reset time. Research demonstrates that the rejuvenation period, which includes sleep time, allows the body’s cells to rejuvenate and regenerate, boosts the immune system, manages appetite and hunger, helps preserve muscle mass, decreases the risk for dementia, as well as enhances mental alertness and mood.1-4 A key benefit of the rejuvenation period is that body fat, especially belly fat, decreases while muscle mass is maintained. 5,6 This reduction in belly fat decreases obesity as well as the risk of type 2 diabetes.7


While on Rapid Results, Jenny Craig members will continue to receive the same support with a personal consultant, who is undergoing new enhanced comprehensive training to deliver excellent weight loss guidance. Members on the study who followed the Rapid Results program lost 30% more weight in their first four weeks when compared to the Classic Program. †

What is the price difference between Rapid Results and the Classic Jenny Craig Program?

There is no price difference.  The Trial, Premium and Super Premium program options will remain the same.  Regardless of program type, including Jenny Craig Anywhere, you can choose to do Rapid Results or the Jenny Craig Classic program.

How does eating more calories during the day help me lose more weight?

From dawn until mid-afternoon, our metabolism is optimal and the body is most efficient at burning calories as fuel. So it makes sense for us to prioritize consuming most of our calories earlier in the day when our metabolism is optimal and avoid eating large meals in the evening, when the body is winding down and getting ready for bed. The Rapid Results menu is balanced with a higher number of calories in the morning/afternoon and fewer calories in the evening to work with these natural peaks and valleys of metabolism.

What if I am not hungry in the morning or during the day? 

Like changing any habit, commit to taking that first step.  One effective way is to map out your meals and snacks throughout the 12-hour nourishment period, then set an alarm on your phone as a reminder to eat.  As you follow through with your plan day by day, you are creating a new pattern that, over time, will become your new norm.  You will discover the feeling of hunger and look forward to your first meal in the morning.

Can I have beverages during the 12-hour Rejuvenation Period?

Yes! You can hydrate with calorie-free beverages like water, plain tea, black coffee or any zero calorie flavored drinks.  You do not want to consume beverages that contain sugar or any calories because that will require your body’s attention to process them and not allow it to rest fully.

Is it okay if the start and stop times for the Nourishment Period and Rejuvenation Period change during the week?

Schedules tend to change day-to-day and especially between weekdays to weekends so it may be necessary to shift your schedule by a couple of hours.  Some days, the time you start your nourishment period could be from 7am to 7pm or 8am to 8pm. As long as you stick to around a 12-hour block for your body to rest and recharge during the rejuvenation break, you can reap the benefits.

I work a night shift.  Can I still do the Rapid ResultsTM program?

Yes! Though the most recent science has shown that because our bodies are affected by the daily 24-hour light-dark cycle, human beings metabolize calories at slower rates during the nighttime.  Therefore, weight loss may take a bit more time.  But here are some suggestions which may help:


•  Try to take your rejuvenation break from consuming calories for around 10-12 hours.

•  Get at least 7 hours of sleep.  

•  Try to get in most of your calories during daylight.
