What Is The 1: 6 Intermittent Fasting Plan

18/6 Intermittent Fasting: Beginner’s Guide to Effective Weight Loss

As a registered dietitian, one of the most common questions I get asked is should I follow an intermittent fasting diet?But what most people dont realize is that intermittent fasting is an umbrella term and can refer to many different styles of eating from time restricted eating to alternate day fasting.

In this article, Ill be discussing the form of time restricted eating called the 18:6 plan, which is one of the most popular forms of intermittent fasting, or IF. The idea behind it is that you fast for 18 hours a day and only eat during a six hour window. For example, if your last meal was at dinner time then you wouldnt eat again for 18 hours, or until 12pm the following day.

With the 18:6 style of time restricted eating, you would eat during the same eating window each day, so you want to be sure the six-hour eating window you choose works for your lifestyle. Many people choose to have a later eating window, eating their daily calories from 12pm-6pm or from 2pm-8pm. However, some research suggests an earlier eating window may offer additional metabolic and health benefits.

Why Would Anyone Intermittent Fast

Intermittent fasting is not a new concept by any means. In fact, the idea surrounding it is to mimic the way our hunter and gatherer ancestors used to eat way back when. They would hunt for food not knowing when their next meal would be. When they caught something, they would feast like they didnât know when their next meal would be .

Today, intermittent fasting has become the adopted term to mimic this ideology in modern society. We artificially famine , followed by eating all of our food in a short window .

There are also many benefits on the body when intermittent fasting. I will cover these later in the article.

It Wasnt Until March 2020 That I Became Consistent In Making A Lifestyle Change

This included the way I viewed food. I chose a low-carb and intermittent fasting eating plan because, after trying several methods to lose weight, this combo was the only one that I felt I could sustain over my lifetime.

I fast for 18 hours and eat within a six-hour window , and I typically only eat two meals per day during my eating window. This is the eating method that works for *me*but you should always check in with a dietitian or doctor before making big changes to your diet.

Losing Weight With 1: 6 Intermittent Fasting

Intermittent Fasting and Working Out

One of the most noticeable benefits of following a fasting plan is the ability to lose weight. Intermittent fasting is proven to help with weight loss, boost metabolism functions, and increase your heart health while giving you more energy.

But how does it work? 18:6 fasting weight loss is triggered by putting your body into a calorie deficit by abstaining from calories for 18 hours a day, which kick-starts your metabolic process.

The ketones produced by your metabolism in this state target fat stores in the body instead of glucose for energy, burning fat rapidly. Plus, the metabolic switch activates several other processes in the body, further assisting with weight loss.

  • The studies have shown that 18 hours of fasting benefits are higher and last longer when compared with other fasting techniques. A study that was published in the New England Journal of Medicine, entitled, Effects of Intermittent Fasting on Health, Aging, and Disease, claimed that intermittent fasting has effectively hacked human metabolism.Evidence is accumulating that eating in a six-hour period and fasting for 18 hours can trigger a metabolic switch from glucose-based to ketone-based energy, with increased stress resistance, increased longevity, and a decreased incidence of diseases, says the study.
  • To take advantage of this fasting method, you get to eat larger meals in a six-hour window. Eat a large breakfast and a fairly decent meal around 3 pm.

    Over time, the benefits of intermittent fastingwhether youre doing 18:6, 16:8, or another planmay be far-reaching and varied, including, potentially:

    • Lower risk of disease

    The benefits of an 18:6 fast are attained a little faster than some of the other types of fasting, says nephrologist Jason Fung, M.D., a world-leading expert on intermittent fasting and low-carb diets and author of The Obesity Code. 18:6 fasting is a more intense fast, so it can produce longer and greater results.

    The idea is simply to give more time in the fasting state, says Fung. Just like 18:6 is more advanced than a 16:8 or a 14:10 fast, Its easier to implement into a regular day and gives structure to the eating schedule.

    18:6 intermittent fasting can prevent, treat, or reverse , says Bowden, who is a weight-loss expert and creator of Meta-Fast.com. In my opinion, insulin resistance is the biggest metabolic pandemic of our time. 88% of Americans have some degree of it and it underlies every major chronic disease, including all the co-morbidities for covid-19, says Bowden.

    What Is Intermittent Fasting And Why Do People Use It

    IF has had a cult following in health and wellness circles for a decade and there are more than a half dozen ways to do it from alternate-day fasting, 5:2, and the OMAD diet.

    Where most diets focus on what to eat, IF is mostly about when to eat, giving your body a prolonged break from the intensive task of breaking down and digesting food. Studies suggest that when your body gets a break from the consuming job of digestion, all kinds of reparative functions may take place throughout the body: inflammation may cool , brain fog may clear, and mental focus may sharpen . Some studies suggest that your risk for metabolic diseases, obesity, and cancer may drop, and weight loss may become a heck of a lot easier.

    • 18:6 is a method of time-restricted eating where you fast for 18 hours and then limit all of your calories to the remaining 6 hours of the day.
    • Before diving into the 18:6 plan, youll want to build up to that timing in increments.
    • Some studies suggest that when your body gets a break from digestion, inflammation may be reduced, brain fog may clear, and mental focus may sharpen.

    What Is The 1: 8 Diet

    The 16:8 diet is a form of intermittent fasting where you break the day into two parts: a 16-hour fasting period and an 8-hour period where you consume all your calories.

    The 16:8 stems from the 8-Hour Diet book by author David Zinczenko and Peter Moore , former editor-in-chief of Men’s Health. The two created the plan off the back of the popular 5:2 diet, with the main difference being the longer fasting time between eating sessions. This, they say, gives the body the time it needs to process food and burn away extra fat.

    The 8-Hour Diet by David Zinczenko and Peter Moore –

    Suzie Sawyer , founder of Nutrition Lifestyle, says, “There are no restrictions on the types or amounts of food that a person can eat during the 8-hour window. This flexibility makes the plan relatively easy to follow.”

    Salmon is an excellent source of omega-3 healthy fats, and dark green veggies like kale and broccoli are high in antioxidants.

    Salmon is one of my personal favorites for its taste and nutrient density, and you can select any wild-caught seafood of your choice.

    Serve alongside some of your favorite vegetables roasted in coconut oil, and you have a quick and easy superfood meal.


    • 4 cloves garlic, finely diced


  • Preheat oven to 400°F.
  • Mix together lemon juice, ghee, and garlic.
  • Place salmon in foil and pour lemon and ghee mixture over the top.
  • Wrap salmon with the foil and place on a baking sheet.
  • Bake for 15 minutes or until salmon is cooked through.
  • If your oven size allows, you can roast your vegetables alongside salmon on a separate baking sheet.
  • How Does Intermittent Fasting Work

    The power of Intermittent Fasting comes in two forms and shapes: caloric restriction and reduced meal frequency .

    An average adult would have breakfast at 8 am, lunch at noon, snack at 3 pm, dinner at 7 pm and then an I cant go to bed being hungry-kind-of-snack at 11 pm.

    Thats five meals over the course of 15 hours and if you dont follow a strict portion control youll most likely consume more calories than you spent that day, which will result in gaining extra weight.

    On top of that, your body will be working all that time digesting the food and will not have enough time left for so-needed recovery activities.

    When following any intermittent fasting schedule you are reducing the meal frequency throughout your day, making it simply harder to eat 3 big meals and 2 snacks within twice or even less time .

    All of this results in a lower chance to go overboard with your calorie consumption and also more time for body to perform recovery operations such as autophagy.

    Making Weight Loss Easier

    Intermittent fasting can change the function of hormones, cells and genes, Sawyer says. “Changes in hormone levels makes stored body fat more accessible and initiates important cellular repair processes. When you fast, insulin levels drop, and human growth hormone increases. Your cells also initiate important cellular repair processes and change which genes they express.”

    Carbohydrates To Eat When Intermittent Fasting

    With intermittent fasting, its smart to focus on whole foods rich in fiber but low in starches.

    While starchy foods increase blood sugar and insulin levels, dietary fibers counteract these effects .

    For this reason, this list puts net carbs in parentheses:

    Due to its high content of resistant starches, sweet potato is the most digestible variety if you want to replenish your carbohydrate stores.

    Unlike conventional starches, resistant starches pass through the small intestine without being converted into glucose.

    Instead of being absorbed as sugar, resistant starches are broken down into short-chain fatty acids, on which your gut bacteria can nourish.

    We will take a closer look at when to eat carbohydrates during intermittent fasting shortly.
