Does Time-Restricted Feeding Work for Men?By Elisa - Jenny Craig Science-Backed
If you’ve spent time looking into some of the most effective weight loss strategies for men, you may have heard the terms intermittent fasting and time-restricted feeding. While intermittent fasting may be too restrictive or daunting for some, time restricted feeding may be more up your alley, and can work naturally into your daily schedule. Its proponents claim it delivers numerous health benefits — including weight loss, lower cholesterol and triglyceride levels, reduced inflammation and improved insulin sensitivity — but what does the research say?1
With so much conflicting information on the internet and developments in evolving research, it can be difficult to get to the bottom of things. Read on as we take an evidence-based approach to understanding the research around time-restricted feeding for men, and provide some easy and practical ways you can incorporate it into your daily life.
What is time-restricted feeding?
Simply put, time-restricted feeding is an eating pattern that involves limiting calorie consumption to a certain time frame, so that your body gets a break from digestion. It typically involves eating all your meals within a 12-hour window and then refraining from food and caloric beverages for the following 12 hours (most of which is spent sleeping). So, if you had your first meal at 8 a.m., you would eat your final meal before 8 p.m., and then wait to enjoy your breakfast the following day until 8 a.m.
The history of time-restricted feeding
Believe it or not, time-restricted feeding is nothing new. Humans have been unintentionally taking extended breaks from consuming food since the beginning of time — since their next meal was never a guarantee. However, unlike our ancestors, our modern society has access to food 24/7, making late-night snacks and meals an all too common occurrence. Today, it’s easy to eat from the time you wake up until the time you fall asleep — which unfortunately can lead to weight gain and other health concerns.2
How does time-restricted feeding work?
Time-restricted feeding synchronizes your eating schedule with your natural circadian rhythm, otherwise known as your body’s internal clock. Your circadian rhythm follows a 24-hour cycle, typically divided into two 12-hour periods, which are dictated by daytime and nighttime. To eat in accordance with this rhythm, time-restricted feeding involves eating during the day when your metabolism is working most optimally and then refraining from food at night, to allow your body time to rest and recover.
A pilot study conducted on a small group of men found that early time-restricted feeding may improve both insulin sensitivity and the pancreas’s ability to respond to rising blood sugar.3 In addition, it found that this type of eating pattern lowered the men’s blood pressure, and reduced their oxidative stress levels and appetite levels in the evening.4 However, more research is needed to conclusively prove these findings.
What are the intended benefits of time-restricted feeding for men?
Beyond weight loss and a reduction in appetite levels, there can be other benefits of time-restricted feeding for men.
1. Build muscle and lose fat
Studies indicate that a key benefit of following an eating pattern such as time-restricted feeding is that body fat tends to decrease while muscle mass is maintained.5 This is because when you give your body a 12-hour or longer break from consuming food, your body starts to burn glucose that is naturally stored in the liver and then turns to burning fat. This helps preserve lean body mass while reducing unwanted fat.6
2. Easy to follow
If you don’t want to follow a complicated calorie counting system in order to lose weight, time-restricted feeding might be right up your alley. Forget worrying about counting calories, simply take note of the time you start eating and when you’ll finish. If you want to take meal prep out of the equation, which a recent study conducted on behalf of Jenny Craig found that nine out of 10 people think that it would help with their weight loss, Jenny Craig offers around 100 nutritious, ready-to-go meal options that will help set you up for weight loss success.7
3. Optimize your metabolism
By eating earlier in the day rather than at night, you’ll be working with your metabolism when it’s functioning most efficiently.8 Your metabolism has a predictable curve; it’s most optimal at burning calories in the morning and winds down in the evening as you’re getting ready for sleep. By following an eating routine such as time-restricted feeding, you’ll be fueling your body at the right times to further support your weight loss efforts.9
Jenny Craig’s newest program, Rapid Results, is based on these findings and leverages the body clock’s natural circadian rhythm to help optimize your metabolism and accelerate weight loss.10
