The Thinking Is That Any Amount Of Calories Can Technically Break A Fast And Should Be Avoided While Youre In A Fasting Window
Technically, fasting means refraining from having any kind of food. As a result, Any amount of calories will break a fast, says Scott Keatley, RD, of Keatley Medical Nutrition Therapy.
The rule of thumb floating around the Internet is that 50 calories will break your fast, but this is based on one random guy’s experience and has been repeated so often that people believe it’s true, he says. But, Keatley emphasizes, Any amount of calories will break a fast the ingested energy will be broken down as quickly as possible and provided to your cells.
Theres unfortunately no hard-and-fast research that gives a set number of calories that are okay for fasting, says Jessica Cording, MS, RD, author of The Little Book of Game-Changers. Plus, she points out, everyones metabolism is different, so what jump-starts you out of a fast may be different from what does the same for your friend.
Also, theres this, per Cording: As soon as you consume enough calories to give your body energy to do anything, that brings you out of that fasting state because your body has been given fuel to work with. Basically, having any amount of calories means you’re rolling the dice with leaving your fasting state.
Eggs To Break The Fast
Eggs are the perfect way to break your fast. An egg is a whole food that contains lots of proteins, vitamins, and nutrients. Egg gets digested quickly, is low in calories, and rich in proteins. It can be a great way to start with eggs because they can make you feel full quickly.
Eggs are easy to cook you can go for a boiled egg, scrambled egg, or an omelet. Few qualities of eggs make it more preferable than other foods to break the fast, which includes:
- Eggs are a high protein food it helps boost your metabolism, burns more calories and aids in weight loss
- Eggs are rich in leucine, which helps in muscle growth
Consumption of eggs also aids in less variation of plasma glucose and insulin. Hence it would be perfect for breaking your fast with eggs.
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.

Mistake #: Youre Pushing Yourself Too Hard
Ive been doing IF almost 2 months, mostly OMAD, sometimes 48/72 hours extended fasts. The last 3 or 4 days whenever I break my fast I feel a great regret. I always feel like I could push the fast a little longer. What should I do?
Extending a fast doesnt supercharge the powers of IF. If this sounds familiar to you, please find yourself a counselor who specializes in eating disorders. Im not saying you, or this person here, has an eating disorder, but food should not induce feelings of remorse or regret. Left untreated, this could develop into a larger problem. And also, huge kudos to this person for so bravely speaking up and sharing their food feelings!

Eating Junk While Intermittent Fasting
Since highly processed foods not only raise blood sugar and insulin levels but also have a severe pro-inflammatory effect, you should avoid them during intermittent fasting .
Therefore, this one also applies to intermittent fasting:
Eat real food, such as on the previous list!
Correspondingly inadequate nutrition during the eating periods can destroy the health benefits of intermittent fasting.
Thus, do not trust any food in colorful packaging and read the labels thoroughly before you seriously consider eating these garbage foods:
- Ready Meals
- Fast food
If you have one of these foods on your meal plan, you wont get any results, even with intermittent fasting.
However The Safe Minimum Temperature May Vary Depending On What You’re Cooking
The CDC notes that some meats require higher minimum temperatures than others. Their experts say that all poultry should be cooked to 165 degrees Fahrenheit, while ground beef, lamb, and pork must reach a minimum of 160 degrees Fahrenheit. Fish can be lower still, at 145 degrees Fahrenheit. Heat other cuts of beef, pork, and lamb, such as veal chops, roasts, and steaks to at least 145 degrees Fahrenheit, then let them stand for three minutes before serving. Doing so enables the food to continue cooking after the microwave turns off and gives food a more consistent temperature throughout, the CDC explains.

Is Intermittent Fasting Safe
Some people try intermitting fasting for weight management, and others use the method to address chronic conditions such as irritable bowel syndrome, high cholesterol or arthritis. But intermittent fasting isnt for everyone.
Williams stresses that before you try intermittent fasting , you should check in with your primary care practitioner first. Some people should steer clear of trying intermittent fasting:
- Children and teens under age 18.
- Women who are pregnant or breastfeeding.
- People with diabetes or blood sugar problems.
- Those with a history of eating disorders.
But, Williams says, people not in these categories who can do intermittent fasting safely can continue the regimen indefinitely. It can be a lifestyle change, she says, and one with benefits.
Keep in mind that intermittent fasting may have different effects on different people. Talk to your doctor if you start experiencing unusual anxiety, headaches, nausea or other symptoms after you start intermittent fasting.
The Magic Process Called Autophagy
Another amazing benefit of fasting is autophagy. This is the process of the human body rejuvenating itself. Through this process, our bodies repair and clean out all the junk in our cells. This benefit is truly awesome and allows you to come back from intermittent fasting feeling like a brand new person!
Some of the other impressive benefits of fasting include increased insulin sensitivity, reduced blood pressure, and improved triglyceride levels.
Knowing about these benefits if encouraging, but lets take a quick look at the sciency stuff behind fasting.

How Can I Suppress Hunger During Intermittent Fasting
Eat high-fiber foods, such as nuts, beans, fruits and vegetables, and high protein foods, including meat, fish, tofu, or nuts, during your eating window, Varady advised. Chewing high-fiber gummies can also help.
Drink lots of water. People tend to think they’re hungry, when they are really just thirsty, she said.
Go for black coffee or tea, or cinnamon or licorice herbal teas. These beverages may have appetite-suppressing effects, Varady noted.
Watch less TV: I know this sounds strange, but while you are watching TV, you are bombarded with dozens of ads for food. This can make you feel hungry, when in actuality, you are not hungry at all, she said.
Remember, being “a little hungry” is the best thing that can happen to you, wrote Madelyn Fernstrom, health and nutrition editor at NBC News, calling it a “true mind-body connection” that helps you recognize fullness.

You Don’t Ease Into It
Skip breakfast. Skip lunch. And by 3 p.m. you’re willing to eat your arm. “If you normally eat every 34 hours and then suddenly shrink your eating period to an 8-hour window, you’ll likely feel hungry all the time and discouraged,” according to Libby Mills, RD, a dietitian at Villanova University’s College of Nursing.
“Deciding to limit your eating hours may be motivated by weight loss. However, this represents an opportunity to reacquaint yourself with what your body is really feeling. We often are eating every 3-4 hours and not always because we are hungry.” Plus, you don’t have to fast all week. In fact, people who follow the 5:2 diet eat regular amounts of healthy food for 5 days, then flip the switch on the other 2 days, by reducing caloric intake. A study involving 107 overweight or obese women found that women who restricted calories twice weekly lost the same amount as those who continuously cut calories.
If You Want To Consume *something* During Your Fasting Window Here Are Your Best Options
Again, fasting by definition means youre not having food, so this is really more about what you can drink. That includes:
- Water. Water is fine, for sure, Keatley says. This includes still or sparkling water, although flavored waters get a little dicey because they usually contain some calories.
- Coffee. Black coffee has about five calories per cup, which is technically not nothing, Keatley points out. Still, he says, most people have black coffee during fasting periods and do just fine. Just skip add-ons like milk, creamer, or sugar. That will have an effect on your fast, Cording says.
- Tea. Brewed tea typically contains the same calories as a cup of black coffee or less. The same rules apply here as they do for coffee, Cording says.
Some people will drink chicken broth or bone broth, or add MCT oil, ghee, or coconut oil to their coffee during a fast, but all of these will break your fast, Cording notes. Broth is kind of surprising, but Cording points out that bone broth in particular has plenty of protein. What can happen is, when you consume the broth, your body uses the amino acids as fuel and then youre not longer in the fasting state, she says.

Moreno recommends also adding fermented foods, omega 3 fatty acids, other anti-inflammatory fatty acids, herbs and spices in non-supplement form, and dairy or dairy substitutes to your meal list as well.
“You only have a 6-12 hour window so its a matter of timing,” she explained. One thing is definitely a must, though. “Avoiding refined starches, added sugars, trans fats, and processed meats still hold true!” Moreno stressed.

Mistake #: Youre Not Sure What Counts
So my wife and I are trying to start on the IF journey . Its harder than we thought. How can she do coffee in the mornings without throwing off the benefits of the fast? She doesnt care for black coffee, but the chokehold of caffeine has her in its stimulant grip, and I dont want to die in that ditch today.
I, too, live and die by that a.m. cup of coffee. But this person is overthinking it. The best thing to do is simplify your routine. Have your morning cup of coffee exactly as you like it and break your fast then. For example, if youre doing 16:8 , have your coffee at 8 a.m. and your last meal at 4 p.m.
Preparing For And Breaking A Fast
With both Ramadan and Yom Kippur this month, many of you may be fasting to honor those events. Check out what you should eat before and after a fast to maintain strength, regain energy and avoid an upset tummy.
In the Jewish religion, Yom Kippur is a holiday focused on atonement and forgiveness. To honor it, followers don’t eat food or drink for about 25 hours. Ramadan, a Islamic holiday that began in late August, is a time for reflection and devotion. Those practicing a Ramadan fast don’t eat during the daylight hours for a whole month. Whether you’re following a religious fast or considering a cleanse, picking the right things to eat before and afterward is essential.
Before the Fast
Leading up to your fast, be sure not to skip meals and eat well so you can be in tip-top shape while you fast. My family observes a Yom Kippur fast just before that 25-hour period begins, I eat a dinner that’s high in fiber, has lots of nutrients and tons of fluids. I also stick to bland foods and avoid anything I know will upset my stomach.
With Ramadan, you are allowed to eat meals after sunset and before sunrise. You may have to shift your usual dining hours and get up earlier for a proper breakfast — be sure to do it, if you can. A good before-fast meal might be a bowl of oatmeal topped with fresh fruit, a scrambled egg on the side and a glass of milk.

You Sabotage With Soda
Mills says the carbonation in soda can mask your sense of hunger, which can set you up for being too hungry at your next meal and lead you to overeat. “Artificially sweetened drinks can also raise the satisfaction bar for sweet tastes, so when you do eat a piece of fruit it may not be satisfying.”
She adds these beverages may also have caffeine, which can affect people differently. “Some caffeine may make you jittery and set you up for craving sweets. While other caffeine may mask your sense of hunger and postpone eating until well past feeling hungry.”
Fasting For 2 Days A Week
People following the 5:2 diet eat standard amounts of healthful food for 5 days and reduce calorie intake on the other 2 days.
During the 2 fasting days, men generally consume 600 calories and women 500 calories.
Typically, people separate their fasting days in the week. For example, they may fast on a Monday and Thursday and eat normally on the other days. There should be at least 1 non-fasting day between fasting days.
There is limited research on the 5:2 diet, which is also known as the Fast diet. A involving 107 overweight or obese women found that restricting calories twice weekly and continuous calorie restriction both led to similar weight loss.
The study also found that this diet reduced insulin levels and improved insulin sensitivity among participants.
A small-scale study looked at the effects of this fasting style in 23 overweight women. Over the course of one menstrual cycle, the women lost 4.8 percent of their body weight and 8.0 percent of their total body fat. However, these measurements returned to normal for most of the women after 5 days of normal eating.

How Does Intermittent Fasting Help You Lose Weight
Intermittent fasting is more about the rules on eating periods as opposed to what you can eat, which is likely why it is sweeping the nation as a popular method for weight loss.
Essentially intermittent fasting helps you lose weight because of the calorie deficit it enforces. So when you skip your breakfast your body breaks down fat stores for fuel rather than getting its fuel from food.
Ultimately, when the energy you take in is less than the amount you are burning off, as in intermittent fasting, the result will be a loss of weight. Simple, huh?
