What Side Effects Can I Expect On An Intermittent Fasting Diet

How Often Should You Do Intermittent Fasting?

For many people, transitioning to eating this way is not easy. Per the April 2019 Nutrients research, IF can lead to migraine, dizziness, nausea, and insomnia. It can also make people feel hungry and weak in general, limiting their activity throughout the day.

Some women might stop menstruating;as a result of calorie restriction,;according to the same Nutrients study.;If you miss three periods in a row, its time to see a doctor, says the Mayo Clinic.

Burning Questions About Intermittent Fasting Answered

Become an expert in everything related to IF: how it works, why its beneficial, who its risky for, and what to know before you start.

Forget counting calories or swearing off carbs the latest diet;fad;doesnt put limitations on whatyou eat. Rather, it focuses on the when. This way of eating is called intermittent fasting , and in the past several years it has risen through the ranks of popular diets, until its now one of the most-searched diets on Google, racking up hundreds of thousands of searches on average each month.

Whats the reason for its popularity? It seems a lot easier for some people. Traditional lifestyle changes tend to rely a lot on calorie counting or point watching or rules, and for some people especially people with busy lives or who feel pulled in a lot of directions that feels like a lot of work and effort. So for this, where they literally have to do nothing but skip a meal, it’s just a lot easier for them to maintain, says Elizabeth;Lowden, MD, a bariatric endocrinologist at the Northwestern Medicine Metabolic Health and Surgical Weight Loss Center at Delnor Hospital in Geneva, Illinois.

Here, we explore the ins and outs of IF, and;answer all the questions youre;probably asking.

Should I Eat 6 Small Meals A Day

There are a few main reasons why diet books recommend six small meals:

1) When you eat a meal, your body does have to burn extra calories ;just to process that meal.;So, the theory is that if you eat all day long with small meals, your body is constantly burning extra calories and your metabolism is firing at optimal capacity, right? Well, thats not true.

Whether you eat 2000 calories spread out throughout the day, or 2000 calories in a small window, your body will;burn the same number of calories processing the food;.

So, the whole keep your metabolism firing at optimum capacity by always eating sounds good in principle, but reality tells a different story.

2) When you eat smaller meals, you might be less likely to overeat during your regular meals.;I can definitely see some truth here, especially for people who struggle with portion control or dont know how much food they should be eating.

However, once you educate yourself and take control of your eating, some might;find that eating six times a day is very prohibitive and requires a lot of effort. I know I do.

Also, because youre eating six small meals, Id argue that you probably never feel full, and you might be MORE likely to eat extra calories during each snack.

Although grounded in seemingly logical;principles, the six meals a day doesnt work for the reason you think it would , and generally only works for people who struggle with portion control .

That Evening However I Encountered My First Challenge: Dinner With Friends

What to Drink and Eat While Intermittent Fasting

Luckily, the friends who invited me over wanted to eat at about 7, well within my “feeding window.” We planned to order takeout, but, unfortunately, some of us arrived late. By the time we ordered, it was 8 p.m., and the food didn’t arrive until 8:30 .

It felt weird to refrain from eating with everyone, so I decided that the next day I would break my fast an hour later to make up for it.

Is It Good Or Bad To Exercise While Intermittent Fasting

According to Harvard Health, one theory is that exercising in a fasted state may help burn fat. Lowden explains that the body needs sugar or some sort of energy to perform well while exercising. Normally, the energy comes from sugar molecules, which are stored as glycogen in the liver. If you start exercising, youre more likely to deplete those stores and then your body has no choice but to go into a more anaerobic breakdown to give you the energy you need, she says. Instead of burning through sugars that aren’t available, your body is forced to burn through another energy source: fat.

But you may not have enough energy to exercise as intensely as you normally would. Peak performance or even feeling good while exercising it’s much easier to do if you eat,;Lowden;says.

How Many Meals To Eat When Intermittent Fasting

As we have just discovered, eating less often keeps insulin levels in check and burn fat. For this reason, science has proven that snacks cannot help you lose weight .

Intermittent fasting, unlike conventional dieting, has the advantage that you can always increase it.

If you like, you can eat only once a day instead of twice or even fast for several days. Thus, it is incredibly flexible.

Nevertheless, you should not immediately overstrain your body when you start intermittent fasting. For example, it is advantageous to establish simple rules when you start:

  • Lunch and dinner only
  • Between the two meals, natural snacks, like a handful of walnuts, are allowed

With time and experience, you will get to know your body better, and you can stop snacks completely or eat one big meal a day.

In any case, an 8-hour eating period is enough to lose weight with the appropriate diet.

Ending A Longer Fast: A Quiet Gut Revs Up Again

Longer-term fasts are different. Resuming eating after a longer fast takes more planning and care.

As we start to incorporate fasting into our routines, our bodies physiologically take a bit of time to adjust to the new regimen, especially if we used to eat constantly. As chronic eaters, our bodies are constantly spending metabolic energy producing digestive enzymes to process the food were consuming. This changes when we first start fasting. The digestive enzymes are not needed or produced.1

Vitamin D Fortified Milk

How Many Meals Should You Eat During Intermittent Fasting?

The recommended intake of calcium for an adult is 1,000 milligrams per day, about what you’d get by drinking three cups of milk per day. With a reduced feeding window, the opportunities to drink this much might be scarce, and so it is important to prioritize high-calcium foods. Vitamin D fortified milk enhances the body’s absorption of calcium and will help to keep bones strong. To boost daily calcium intake, you can add milk to smoothies or cereal, or even just drink it with meals. If you’re not a fan of the beverage, non-dairy sources high in calcium include tofu and soy products, as well as leafy greens like kale.

Here’s A Quick Refresher On What It Means To Do Intermittent Fasting

Before we get into what you can and cant eat and drink, its a good idea to go over what intermittent fasting involves in the first place. Intermittent fasting focuses on following a pattern of periods of eating and fasting, i.e., times when you eat and dont eat. Intermittent fasting usually involves fasting for a certain number of hours or even days that are spaced out during the week.

There are plenty of types of intermittent fasting to choose from, but some of the more popular forms include the 16:8 diet, where you fast for 16 hours a day and eat only during eight hours , and the 5:2 diet, where you eat less than 500 calories for two non-consecutive days a week and eat normally for the rest of the time.

Research has linked intermittent fasting with lower insulin levels and blood pressure, and increased appetite control. Some people also lose weight while intermittent fasting.

Can Intermittent Fasting Help You Lose Weight

The short answer: probably. IF gets a lot of press as a weight loss tool, and I recommend it in my practice for weight loss and weight management, Dr. Gottfried says. Its linked to weight loss because not eating between meals forces the body to turn to the fat stored in cells for energy, according to Harvard Health. Insulin levels decline through this process as the body burns fat.

Lowden believes what it really comes down to, though, is calorie restriction. Overall, people tend to consume fewer calories in a smaller window of time compared with eating all day, and that’s what leads to weight loss, she says. A study published in June 2018 in Nutrition and Healthy Aging involving 23 obese adults found the study participants took in about 300 fewer calories per day when participating in the 16:8 approach to IF.

Versions of IF that restrict eating after a certain time,;say;7 p.m.,;also help;eliminate nighttime eating, which;has been shown to;contribute to metabolic syndrome and obesity, according to a;study published in December 2018 in BMC Public Health.

Unlike other intermittent fasting diets, each day of the 16:8 works independently to the other days. This means that you can do anywhere from one day of intermittent 16:8 fasting to seven days a week, depending on your goals and the advice from your GP.

Evidence differs, however, on whether its healthy to do intermittent fasting all the time for a number of reasons.

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.

Fast For 12 Hours A Day

The rules for this diet are simple. A person needs to decide on and adhere to a 12-hour fasting window every day.

According to some researchers, fasting for 1016 hours can cause the body to turn its fat stores into energy, which releases ketones into the bloodstream. This should encourage weight loss.

This type of intermittent fasting plan may be a good option for beginners. This is because the fasting window is relatively small, much of the fasting occurs during sleep, and the person can consume the same number of calories each day.

The easiest way to do the 12-hour fast is to include the period of sleep in the fasting window.

For example, a person could choose to fast between 7 p.m. and 7 a.m. They would need to finish their dinner before 7 p.m. and wait until 7 a.m. to eat breakfast but would be asleep for much of the time in between.

What Is The 1: 8 Diet

The 16:8 diet is a type of intermittent fasting where you break each day into two parts a 16 hour stretch and an 8 hour period. For 16 hours every day, you consume nothing but water, coffee, tea and other unsweetened drinks. Then for the other eight hours of the day, you can eat all your meals and snacks.

The 16 hour stretch sounds like a long time, but if youre getting enough sleep, you should be asleep for about half of that time.

Sports Scientist Harry Aitken tells GoodtoKnow, Intermittent fasting is a dietary technique in which all food is consumed within a relatively small window of time. Fasting is going for a significant period of time without eating, and intermittent fasting simply brings in a small window of time where you are able to eat.

Intermittent fasting has been popularised and studies have gone on to confirm that it leads to weight loss and fat loss.

The 16:8 diet stems from the book 8 Hour Diet by author David Zinczenko and editor-in-chief of Mens Health Peter Moore, who suggested that a longer fasting time between eating gives the body the time it needs to process the food and burn away extra fat.
