Does Intermittent Fasting Have Any Side Effects

How To Break Your Fast: What To Eat When You Break Your Fast | Intermittent Fasting

There are a few things that can happen when you follow an intermittent fasting diet. One thing to note is that fasting can interfere with your hunger cues. Since people are only allowing themselves to eat in a certain window of time, they are completely ignoring their internal cues of hunger, Rumsey says. It causes people to disregard hunger cues, which then means once they are allowed to eat, they are starving and it can be hard to stop eating. This could lead to an unhealthy obsession with food for some people, Rumsey says.

Some fasters find that the diet makes them feel sharper and more alert, but alternately, fasting for long periods can also lead to mental fogginess, disrupted sleep, and decreased alertness, Rumsey says. And, she adds, fasting for extended periods of time takes a large toll on your blood sugar levels, causing you to flip-flop between low blood sugar and a spike when you eat again.

To celebrate the store’s opening, there were plates stacked high with free alfajores delicious South American cookies sandwiched together with a layer of dulce de leche. I quickly polished off four alfajores, which I later calculated had more calories than one of my normal meals and way more sugar and refined carbs than I would normally eat in a day. But hey I didn’t break my diet!

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.”

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.

What Can You Eat

What to Drink and Eat While Intermittent Fasting

The 5:2 diet restricts calories to just 500 a day for women and 600 a day for men on two fasting days. On the other five days, you eat normally. But according to “The Fast Diet” book, eating “normally” means that you eat the number of calories your body needs to perform daily functions .

That means you shouldn’t overindulge on non-fasting days. Instead, you are encouraged to eat reasonable portions of a wide range of foods.

A large part of the appeal of the 5:2 diet is its simplicity. There aren’t any complicated meal plans to follow and you don’t have to measure portions or count calories.

Instead of focusing on how many carbs you’re eating or how much protein certain foods have, the primary focus of the 5:2 diet is meal timing.

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:

  • Mushrooms
  • Pistachios
  • Sweet potatoes

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.

There Are Certain Foods You Should Avoid

Miami-based dietician Monica Moreno agreed. “Food quality and quantity must indeed be honored!” she told INSIDER. 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.

The If Diet I Followed

I chose to go with the 8:16 diet, because there was no way I wanted to go two whole days without eating. Smith agreed, noting that “for most people the 12-14 hour overnight fast is feasible.” When I asked her advice, Smith recommended that I actually work my way up to the 8:16 method: start by doing 12 hours on, 12 hours off until I could work my way up to 8 on, 16 off. Every day ended up looking different for me, but on an average day my schedule looked like this:

7:30 a.m. Wake up8:30 a.m. Walk 30 minutes to work, Grab a coffee10:30 a.m. Snack 12 p.m. Snack 2 p.m. Lunch6:30 p.m. 1 Hour of Exercise7:45 p.m. Dinner11 p.m. Sleep

This routine is fairly welcoming to the IF diet, but my weeks contain a lot of random things from babysitting to dinner with friends, so I was worried that my slightly chaotic lifestyle would inhibit my success. All that said, I still thought it was worth a try.

The Morning Hunger Was Real

Im not huge on breakfast, but I start desk snacking at 10:30 a.m. every day almost religiously. For the first three days this wasnt a huge issue because I was only fasting for 12 hours. I stopped eating most nights at 9 p.m. and had the green light again at the same time the next morning. But when I upped that no-go window to 16 hours on day four, my rumbling stomach was hard to ignore until noon. Smith had warned me that the hunger often leads to binging, so I was careful not to start shoveling handfuls of chips into my mouth when the clock struck 12. Instead, I ate either an apple or banana with peanut butter to keep my snacks portioned until I ate a bigger meal around 2.

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.

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.

Special Notes If You Try The Extreme Intermittent Fast

1) If youre going to try a fat fast or do extreme intermittent fasting, you want to ease into it.

You do not want to jump into these extreme fasts if you currently eat a poor diet that is filled with fast foods, processed foods, and refined carbs.

If you take this leap, youll find yourself in the bathroom for most of the day. Instead, work your way up to doing these extreme forms of intermittent fasting by first doing a 16:8 fast by itself and getting off the junk food.

2) There is some research that talks about doing a fat fast for a few days up to a few weeks at a time.

My husband and I do not have any personal experience with doing a fat fast for this long and dont promote staying on an extreme fast for more than a day.

When my husband utilizes this fasting technique, he does it one day at a time. This one-day extreme intermittent fast is a good way to change things up, which can stimulate a sluggish metabolism.

When To Eat Carbs On Intermittent Fasting

Since no essential carbohydrates exist, the body does not need them to survive. However, our body cannot produce essential fatty acids and amino acids.

But because it can produce glucose through gluconeogenesis, blood sugar levels remain stable if you eat zero carbs .

Nevertheless, there are situations with intermittent fasting where carbohydrates can fit well into the diet.

For example, many athletes do not want to do without carbohydrates, as they continuously empty their glycogen stores. Adding carbohydrates to their diet can contribute to muscle recovery .

Thus, you can time carbohydrates very well during intermittent fasting:

  • Training day: More carbohydrates replenishing glycogen stores in the muscles
  • Rest day: low-carb or ketogenic diet

Accordingly, you can adapt your intermittent fasting plan to athletic needs through carb-cycling or cyclical ketogenic nutrition.

Nevertheless, so-called loading days are not necessary for muscle building as long as the protein supply is given .

Although the insulin levels increased by carbohydrates can help the muscles recover, it also helps build body fat more efficiently .

For this reason, bodybuilders often claim that they cant gain muscle without also building up body fat.

In short, a low carbohydrate ketogenic diet is still the best option if losing weight is your primary goal.

Other Plans Besides Intermittent Fasting : 4 For Beginners

How Often Should You Do Intermittent Fasting?

If youre new to intermittent fasting, it involves eating during a window of time and fasting the other part of the day. Quite oftenbecause it makes the most senseparticipants schedule their fasting window while sleeping. After all, its hard to be tempted by food while you are snoozing for six to eight hours.

If youre curious about the numbers, 20 4 intermittent fasting means fasting for 20 hours while eating for four hours. Please note that doesnt mean that you eat the entire four-hour time period. It simply involves being able to eat within that time frame.

That being said, there are recommended plans for those who are just starting with intermittent fasting. We suggest starting from the top and working your endurance down to the bottom for time-centric intermittent fasting.

  • 14/10 – This plan involves 10 hours of eating with a 14-hour fasting window.
  • 16/8 – This is one of the most popular methods for beginners, where participants fast for 16 hours and consume for eight.
  • 18/6 – Another popular plan, this schedule has a six-hour window for eating.

When you are building endurance, you can do intermediate steps. For example, when considering intermittent fasting 16/8 vs 20/4 fasting, you can build up your tolerance over time. Start with 16/8, move to 17/7, then to 18/6, and go hour by hour until you build up to an intermittent fasting 20/4 schedule.

What Liquids Can I Drink While Fasting

During a fast, you are to refrain from food but not drinking. As a matter of fact, liquids are important to maintain yourself hydrated.

You can still drink certain beverages and reap the full of benefits of fasting. Here are the top selections:

WaterThis ones a no-brainer. Steady sipping on H2O will keep you hydrated while fasting.

Bone brothUnlike regular broth, bone broth is rich in nutrients such as calcium, magnesium, other trace minerals, as well as collagen, an essential protein for skin, joints, and hair.

Bone broth is often called liquid fuel because of its nutritional benefits. It has proven to improve joint health and replenish electrolytes, which are beneficial during a fast.

Black CoffeeYAS!! Coffee can help curb appetite during a fast but one drawback- no sugar or cream. You can add artificial sweeteners and a splash of cream but make sure to keep your intake under 50 calories. More about drinking coffee while fasting here.

Herbal teasSame as water, decaffeinated tea is a great way to stay hydrated and can even help curb appetite. Be sure to drink it plain, no cream or sugar, at least while youre fasting.

Bulletproof CoffeeThis coffee has around 230 calories so its not a good option to drink while fasting. However, Bulletproof Coffee is one of the best ways to break your fast.

The Difference Between Short And Long Fasts

Every night when we stop eating and then go to bed, we go through a short-term fast until our first meal of the next day. Depending on when you ate dinner and when you consume your first meal after you wake up, you can easily go through a 12 to 16-hour fast with no physiologic change to digestive functions.

Although there is no clear consensus or accepted definition about what the cut off is between a short and a long-term fast, Diet Doctor defines anything less than 24 hours as time-restricted eating, fasts between 24 and 36 hours as a short-term fast, and anything longer than 36 hours a long-term fast.

Time-restricted eating and short-term fasts dont require specific precautions when breaking the fast. Just remember it is a good idea not to binge on highly-processed, sugary, or high-carb foods because you will undo the advantages of the fast. Plan to eat a wholesome, low-carb, high-fat meal, such as any of the meals featured in the Diet Doctor recipes, and you will be just fine.

What Is The Best Way To Get Started On A Fasting Diet

In addition to considering your health goals, follow these steps before diving into IF:

  • Talk to your primary care doctor. He or she can determine if this eating style would be beneficial for your body. If you have questions about what is right for you, it’s important to talk to healthcare professionals, Lowden says. Everybody is an individual and your specific doctor might have preferences about what you do and don’t do based on your specific circumstances.
  • Choose the best type of IF for you. For instance, if you often socialize late at night, 5:2 likely will be a better fit than 16:8. If you decide to try 16:8, Gottfried says to ease into it. I recommend starting slowly at first and ramping up, with a 12-hour fast and a 12-hour eating window, then move to a 14-hour fast with a 10-hour eating window, and from there to 16:8, she says. She also says to keep in mind that there is flexibility with the eating and fasting window. Some like to eat at 10 a.m. and stop at 6 p.m. others prefer to wait until 12 p.m. and stop eating at 8 p.m., she says. Find what works for you.
  • Make sure you have water handy. The 2019 Nutrients study suggests drinking plenty of water during the day to reduce your risk of dehydration and to help replace fluids that you normally would source from foods.
  • Limit physical activity. Its also a good idea to limit your activities during your fasting windows until you know how your body will react, Gottfried says.
