What Can I Eat While Intermittent Fasting

Acceptable Liquids with Intermittent Fasting || Liquids during fasting period

During the times when youre not eating, water and zero-calorie beverages such as black coffee and tea are permitted.

And during your eating periods, eating normally does not mean going crazy. Youre not likely to lose weight or get healthier if you pack your feeding times with high-calorie junk food, super-sized fried items and treats.

But what Williams likes about intermittent fasting is that it allows for a range of different foods to be eaten and enjoyed. We want people to be mindful and take pleasure in eating good, nutritious food, she says. She adds that eating with others and sharing the mealtime experience adds satisfaction and supports good health.

Williams, like most nutrition experts, regards the Mediterranean diet as a good blueprint of what to eat, whether youre trying intermittent fasting or not. You can hardly go wrong when you pick complex, unrefined carbohydrates such as whole grains, leafy greens, healthy fats and lean protein.

Can You Drink Or Eat Anything While Fasting

Yes, you can drink while fasting but you cannot eat while fasting. All solid foods have calories and therefore, they will break your fast.

After a 12-hour fast, I sometimesdrink a cup of Bulletproof Coffee to push me through 4 to 5 additional fasting hours.

Bulletproof coffee is not a zero-calorie drink however, there have been studies that have shown that the health benefits outweigh the fast, and that is why after 12 hours, I choose to extend the fast with it.

Bulletproof coffee does not cause an insulin spike, and theres additional research showing that your fasting continues even though it has calories. Each body is different, and therefore, its something to test out.

One Exception To The Rule

There is an exception to the no-cal rule while intermittent fasting. If you prefer your coffee with cream and sugar, that’s still on the menu with the 5:2 intermittent fasting method. The reason has to do with how you restrict your caloric intake.

The 5:2 method differs from the 16:8 method, where you’re only supposed to consume calories during a certain period of time each day. The 5:2 method, however, doesn’t restrict you to a certain time period. Rather, it restricts how many calories you consume for certain days of the week.

The 5:2 intermittent fasting method means that five days out of the week you consume a recommended amount of calories for your height, weight, age, and sex. But for two, nonconsecutive days of the week you cut your caloric intake down to about 20% to 25% of your recommended amount.

Therefore, you can consume whatever you like on the 5:2 method including a cappuccino at 8 am, if so choose. You just have to be aware of how that will count toward your total caloric intake on those two restrictive days.

For Coaches: Find The Best Intermittent Fasting Schedule For Your Clients

The topic of IF poses quite a few challenges for nutrition coaches. First, some clients really shouldnt be fasting at all. Others might do okay with some fasting approaches, but miserably on others.

And still other clients might come to you convinced that the most extreme fasting method is right for them, even though theyve never fasted before.

How do you navigate these turbulent waters? In this section, youll find advice from Robin Beier, PN2, a German nutrition coach we mentioned earlier in this chapter.

To match clients with an intermittent fasting schedule, consider these questions.

Factor #1: Have they practiced the fundamentals?

A number of fundamental nutrition strategies form the underpinning of all successful IF schedules. Your client will want to have these down before trying any fasting style. Is your client usually

  • eating only when physically hungry?
  • eating slowly until satisfied?
  • consuming minimally-processed whole foods?
  • eating balanced meals that include lean protein, healthy fats, smart carbs and colorful veggies?

If possible, try to spend some time on these practices before diving into any of the fasting schedules mentioned in this chapter.

Factor #2: Have they fasted before? If so, how did it go?

Consider asking: What experiences have you had with fasting schedules or meal skipping?

Factor #3: What kind of exercise are they doing? And how often are they doing it?

Factor #4: Whats their lifestyle like?

Two words that can reign in overzealous clients

Schedule #: 1: : 4 Omad And Other Types Of Time Restricted Feeding

Pin on intermittent fasting

Popularized and researched by Satchidananda Panda, PhD, time-restricted feeding combines a fasting window with a feeding window. During the fasting window, people either dont eat at all or eat much less than usual. During the feeding window, people may either eat normally or more than normal.

In theory, this protocol takes advantage of our natural circadian rhythm to optimize metabolic health.

What it involves

Three of the more popular types of time-restricted eating include:

  • 16:8, which calls for a 16-hour fast followed by an 8-hour eating window.
  • 20:4, which entails fasting for the first 20 hours of each day, and then eating only during a 4-hour overfeeding window. Generally, most people put their 4-hour overfeeding window at the end of the day, as its more convenient for family dinners and after-work training sessions.
  • OMAD, or one meal a day, which involves consuming all of your calories within 1 hour and nothing for the other 23 hours.

In each approach, some people focus on including highly-satiating foods such as colorful veggies and lean protein. These foods can help to dampen hunger during the fasting window.

For someone following 16:8, it might look like this:

Monday, 8pm: Finish your last meal of the day.

Tuesday, 11am: Work out.

Tuesday, 12pm: Eat your first meal, ideally the biggest one of the day.

Tuesday, 12-8pm: Feeding window during which you eat your daily energy intake.

Tuesday, 8pm: Last meal of the day ends, and the fasting period starts.

    What You Can Eat And Drink During A Fast

    Okay, so lets consider the reasons we listed above for why people fast and try to figure what you can eat and drink during your fast for each of these reasons.

    1. Fasting for fat loss and weight loss

    To answer the question of what you can eat and drink during your fast when your primary goal is weight loss, we must first consider how fasting helps with weight loss in the first place.

    In short, the general line of thinking goes like this: When doing IF, the fasting periods result in lower insulin levels and higher human growth hormone levels which, in turn, cause increased fat burning and, consequently, weight loss.

    Is this, however, an accurate description of what happens? Well, according to scientific research, its true that, when we fast, our insulin levels drop and our HGH levels increase. What does research show, however, with regards to the end result, i.e. actual fat and weight loss? Do fasting-related lower insulin levels and higher growth hormone levels really result in more fat loss?

    With regards to human growth hormone, research on intermittent fasting can shed some light. In short, studies that have compared intermittent fasting approaches to continuous energy restriction while controlling for caloric and protein intakes, such as this one, this one, and this one, have shown that, overall, the two diet types result in identical outcomes in terms of body weight and body fat reduction.

    2. Fasting for better health

    What Is Intermittent Fasting

    Intermittent fasting is an eating pattern that alternates periods of eating with periods of either not eating or taking in minimal calories. It emphasizes when you eat rather than what you eat.

    Even though it has recently gained mainstream attention, intermittent fasting isnt new. People have practiced periods of fasting throughout history, such as for spiritual, health, or survival reasons .

    The intent of intermittent fasting isnt necessarily only to restrict calories, but also to allow your body to focus on maintenance and recovery, rather than digesting.

    Many fasting patterns incorporate regular 12- to 16-hour periods of fasting into each day, while others include fasting for 24 or 48 hours once or twice per week.

    When you fast, your body undergoes a number of metabolic changes. After some time, fasting causes your body to enter ketosis, a state in which fat is used for energy when carbohydrates are unavailable (


    Intermittent fasting rotates periods of fasting and periods of eating. Its often used for health purposes like weight loss and chronic disease prevention, though its been used historically for other reasons.

    Fasting Can Be Detrimental To The Health Of Some With Underlying Conditions

    “People with diabetes or those who take medications for heart conditions may find fasting to be dangerous. It is important to check with your primary care physician before moving forward with any drastic diet and lifestyle changes,” says Wilson. “The IFers you follow on social media likely don’t discuss this potential problem, so you have to be an informed consumer of social media and make sure it is a safe endeavor on which to embark given your personal health history.”

    When Should I Exercise

    When Varady and her colleagues conducted a study that combined alternate day fasting and exercise, they allowed the participants to pick whether they wanted to exercise on a feasting or fasting day, and found there was no strong preference one way or the other. But the researchers were surprised the dieters actually reported feeling more energetic on fasting days.
