Hi, I’m Heather Lake, a health and lifestyle contributor for Jenny Craig. This is your healthy tip for the week: Try time-restricted feeding or a Daylight Nutrition Strategy. Follow your body’s natural circadian rhythm and eat the majority of your meals during the daylight hours. The concept is simple: Eat during a 12-hour time period (say 8 a.m. to 8 p.m.) and refrain from food and caloric beverages for the remaining 12 hours (this is when you sleep!). By eating in tandem with your natural rhythm, you’re working with your metabolism when it’s working most optimally and letting it rest when it naturally isn’t working as hard. Jenny Craig’s most effective program, Rapid Results, includes this strategy to help you see results sooner!

What is time-restricted eating?

Time-restricted eating, also called time-restricted feeding (TRF), is a weight loss strategy that emphasizes eating meals and snacks within a certain time period — but it’s not really as “restrictive” as it might sound. 

A time-restricted diet, like Jenny Craig’s Rapid Results program, provides a balanced meal plan that offers breakfast, lunch, dinner, snacks and even dessert! Jenny Craig’s take on time-restricted eating is referred to as a “Daylight Nutrition Strategy,” and encourages you to follow your body’s circadian rhythms, natural processes that follow a 24-hour cycle of light and dark.1 On Rapid Results, you’ll eat throughout the first 12 hours of the day during daylight hours and then allow your body to rest and digest during the remaining 12 hours — most of which is spent sleeping. So, if you ate your first meal at 8 a.m., you would enjoy your last meal of the day before 8 p.m. 

Time-restricted eating and circadian rhythms

Support your metabolism. Your metabolism is a series of chemical reactions that happen in every cell of your body, helping to turn the food you eat into energy. Your body burns calories while it works to digest food, absorb the food’s nutrients, and turn those nutrients into energy; all of this may be impacted by your circadian rhythms, experts say. This process isn’t as efficient at night as it is in the morning, they explain.2 One study found that eating late at night may be linked to a higher risk of prediabetes and high blood pressure,3,4 so enjoying your meals earlier in the day may help bolster better health, too.

Feel satisfied throughout the day. “Front-loading,” or eating a higher-calorie meal earlier in the day, followed by a reduced-calorie dinner at night, may be linked to weight loss, one study found.5 Overweight women who ate a high-protein breakfast in the morning and a lighter dinner at night, lost a significant amount of weight compared to those who skimped on breakfast and ate a calorie-rich dinner.5 Rapid Results menus are structured in a similar way — you’ll enjoy a hearty breakfast in the morning (the most important meal of the day!) and your subsequent meals will slightly taper in calories as you approach evening.

Sleep well at night. Your circadian rhythms also influence your sleeping patterns,1 which can be affected by when you eat. Eating food close to when you fall asleep may result in negative sleep patterns, one study found.6 And because poor sleep may be connected to weight gain, getting your zzz’s is key! With Jenny Craig’s Rapid Results program, you can structure your meals around your schedule to ensure you have plenty of time to digest before bed.

Whether you’re struggling with weight loss or are just starting on your journey, a time-restricted diet like Rapid Results could help you to learn and benefit from healthy habits, all while supporting your weight loss efforts.
