Avoid Going To Bed Hungry

Intermittent Fasting & Late Night Snacking

If you can avoid it, dont sleep on an empty stomach. Being hungry causes your bodys cortisolthe stress hormonelevels to rise. The stress placed on your body makes it difficult to relax and at nighttime this affects your ability to fall asleep peacefully.

Ideally, plan your eating schedule so your last meal is 3 hours before you sleep. Like we mentioned previously, if you eat even a healthy late night snack too close to your bedtime, your bodys digestive process will leave you awake rather than helping you relax.

Taking The Easy Way Out

The original intermittent fasting approach was based on human cycles you had a “sympathetic/active” phase and a “para-sympathetic/rest and recover” phase:

  • Sympathetic/active phase: Don’t eat
  • Para-sympathetic/rest and recover: Eat

Simple. Basically, this meant not eating during the day when you’re active and then eating in the evening when you have to recover. You used food to help put yourself in the best physiological/neurological state for what you had to do.

Nowadays a lot of people do an easy version of intermittent fasting. They count the time they’re sleeping as fasting. For example, they stop eating at 8 PM and start eating again at noon the next day .

Of course, the first issue is as we saw earlier they’re not truly fasted for 16 hours. But the other problem is that not eating while sleeping doesn’t have the same effect as not eating while you’re physically active.

Do you know what I call it when I stop eating at 8 PM and start eating at noon the next day? Skipping breakfast. That happens to be the most common habit of overweight people.

So let’s look at an intermittent fasting guy who stops eating at 8 PM and starts again at noon. He goes to bed at 11 PM and wakes up at 7 AM. So he spends 8 hours sleeping and counts those hours as part of his fasting period. But in reality it’s closer to 3 hours.

Fasting At Night Or In The Morning Listen To Your Biological Clock Says New Research

In recent years, diet trends such as Intermittent Fasting have popularized the practice of delayed or restricted eating for many individuals looking to manage caloric intake. Still, many people open to restructuring their schedules have the same question: When is the right time to avoid eating?

According to a new study published in the journal PLoS Biology by biological science researchers at Vanderbilt, the answer to eating windows lies in the circadian rhythms of the bodys biological clock.

There are a lot of studies on both animals and humans that suggest its not only about how much you eat, but rather when you eat, said Carl Johnson, Cornelius Vanderbilt Professor of Biological Sciences and lead author on the research. Our research looked to test the findings of existing fasting studies by asking real humans to participate in a multi-day test for two different meal time routines. What we found is that the bodys circadian rhythms regulate nighttime fat burning.

The study, led by Johnson and Vanderbilt post-graduate student Kevin Kelly, tested meal time restriction by monitoring the metabolism of middle-aged and older subjects in a whole-room respiratory chamber, under controlled conditions, over two separate 56-hour sessionsboth with the same overnight fasting period.

The project is funded by the National Institute of Neurological Disorders and Stroke and the National Institutes of Health.

Avoid Eating At Irregular Times

The times you eat can affect your bodys circadian rhythm. When you eat, your body temperature rises. However, to best fall asleep, your body temperature should drop. So eating at the wrong times will make it difficult for your body to cool down for sleep, which can make it more difficult to fall asleep if youre a hot sleeper vs a cold sleeper.

How To Successfully Do The : 4 Intermittent Fast

Understand what is intermittent fasting in an easy way

The Warrior Diet plan involves fasting for 20 hours during the day followed by overeating in a 4-hour window at night.

For example, you may set your feeding window at 6:00 pm to 10:00 pm. During this time you can eat as much as you want with an emphasis on unprocessed, organic whole foods particularly those high in dietary fats and protein.

After 10:00 pm, you fast or eat very small portions of specific foods such as raw fruit and vegetables until 6:00 pm the next day. Its important youre eating as fewer calories as possible during this time.

The method is best suited for people who have tried intermittent fasting before or who already consume a low-carb/ketogenic diet.

Hofmekler recommends you follow a three-week, three-phase plan initially before starting the Warrior Diet. This helps the body adapt to the eating and fasting schedule and become accustomed to using body fat as energy. This three-week introduction includes:

  • Phase 1 Detox4-hour evening eating period: consume salad with a dressing and a large or a couple of smaller meals of plant protein, whole grains, cheese and cooked vegetables.20-hour fast: consume vegetable juices, bone broth, yoghurt, cottage cheese, hard-boiled eggs, raw fruit and raw vegetables. Black coffee, tea, water and small portions of milk can be consumed during the fasting period.
  • Once you have completed the three-phase diet, it is recommended you start it again before following the 20:4 guidelines.

    Fast At Night To Create A Time

    You have probably always known that late-night snacking was bad for your waistline, but until recently there hasnt been a lot of research to support this theory.

    A series of studies done by scientists from San Diegos Salk Institute for Biological Studies found that restricting eating times for mice prevented obesity and the health problems that come with it, like diabetes, fatty liver, and metabolic problems.

    In the study, one group of mice was allowed to graze all day and eat whenever they wanted. A second group was fed the same amount of calories but was restricted to an eating window of nine, 12 or 15 hours.

    During the nine-month study, some of the mice in the time-restricted eating group were allowed to loosen up their eating briefly on the weekends and eat whenever they wanted a snack.

    Even more encouraging, when mice in the free-to-eat-anytime group were switched to the time-restricted schedule, they lost weight.

    Dont Go To Bed Too Hungry

    Relaxing into sleep might be more difficult if your stomach is grumbling. When youre hungry, your levels of cortisol a stress hormone rise, which can diminish your sleep quality.

    Aim to schedule your last meal at least three hours before bed. This way, your digestion wont disturb your sleep, but you wont go to bed starving, either.

    Adjusting To An Intermittent Fasting Eating Style

    It can be difficult to switch from an all-day eating style to a routine that includes 16 or 24 hours of fasting, so you may want to ease into the practice. Start out by skipping breakfast for a few days to get used to fasting until noon, or stop eating late-night snacks for a few days to shorten your eating window. Gradually shrink the window until youre used to eating during the desired number of hours without feeling hunger pangs.

    Its important to stay hydrated when youre outside of your eating window. Water, black coffee and unsweetened tea are all acceptable beverages that wont break your fast.

    Researchers are still studying the benefits of intermittent fasting, but some studies have shown that the eating style can help people lose weight in the short term.

    Special considerations should be made if you have ongoing health problems and you should consult with a physician before pursuing major dietary changes.

    How Does Intermittent Fasting Affect Sleep

    What to Eat at Night to Lose Weight – All You Need to Know

    Research suggests intermittent fasting may improve the quality of your sleep by reinforcing your circadian rhythms. Your circadian rhythms manage a host of biological functions, from your appetite and metabolism to your sleep-wake cycle. Your circadian rhythm primarily relies on sunlight to regulate these functions, but food is a powerful secondary circadian zeitgeber, or time cue. Following set meal times, as one does during fasting, can help reinforce your natural circadian rhythms.

    People who practice intermittent fasting also have higher levels of human growth hormone. Produced during sleep, this hormone burns fat, restores muscles, and helps the body repair itself at a cellular level. As a result, people who fast may wake up feeling more refreshed and restored after sleeping.

    People engaged in intermittent fasting may also notice they have more energy and focus. Fasting increases production of orexin-A, a neurotransmitter tied to alertness. Specifically, people who fast have lower orexin-A levels at night, and higher levels in the daytime, so they feel more alert during the day and enjoy more restful sleep.

    What Is Fasting And How Does It Work

    A good rule of thumb for those wanting to fast to improve their metabolic and overall health is to leave at least 12 hours between meals ideally more on a regular basis, according to Dr Adam Collins, Principal Teaching Fellow in Nutrition at the University of Surrey.

    Time-restricted eating is often used for weight-loss, and some people increase the daily fasting period to 14 hours or 16 hours. There are other forms of intermittent fasting, including the 5:2 approach, which involves very restricted eating on two days of the week, with normal eating on the other five. The 4:3, or every other day, approach involves similar restrictions on alternate days. Whichever one you choose, make sure youre doing it consistently, Dr Collins advises.

    What Happens If You Eat Once A Day

    Eating one meal a day can increase your blood pressure and cholesterol . This occurred in a group of healthy adults who switched to one meal a day to participate in a study. If you already have concerns in either area, eating just once a day might not be safe. Eating one meal late can cause your blood sugar to spike.

    Some General Safety Tips

    • Drink water when you are thirsty.
    • Adjust your caloric intake during your feeding windows so that you consume enough calories to meet your energy needs according to your weight goals.
    • If you feel faint, dizzy or nauseous, we recommend breaking your fast early and speaking with your primary care physician. You may have symptoms of low blood sugar or another issue.
    • Talk to your physician before upping your fasting window beyond 18 hours per day.
    • Break your fast with low glycemic index foods, such as lean protein and healthy fats like avocados
    • Never do fasts longer than 2 days by yourself. Always tell someone, a family member or friend and keep them updated on how you are feeling as you progress.
    • During fasts longer than 2 days, watch for signs of electrolyte imbalance: muscle spasms, weakness, blood pressure changes, irregular heartbeat, numbness and confusion.

    Intermittent fasting is a method of eating in which a person only eats during specific times of the day. While intermittent fasting has gotten highly popular in recent years, fasting to improve your health originated in ancient history and evolved with various cultures across the globe.

    When intermittent fasting, people generally restrict their fasting times to 10 or more hours of the day and eat during the other portion. Other intermittent fasters may have one or more days of the week where they limit their caloric intake immensely or stop eating entirely.

    Not only can intermittent fasting help with weight loss, but it also provides numerous benefits for your sleep. Lets take a closer look!

    You Must Listen To Your Body And Not The Clock To Understand What Real Hunger Feels Like

    I am guilty of judging what I eat based on the clock. Dan tells me off all the time about it. Yeah, I know Ive got work to do

    Intermittent fasting is based on how you are actually feeling and if you need to eat rather than simply wanting to eat because thats what youre used to doing.

    In the beginning, you may feel super hungry, because youve upset you hunger hormone ghrelin. And its going nuts thinking youre heading into starvation mode which of course youre not.

    These hungry pains and intense feelings to eat normally subsided in the first 2-3 fast periods you do and your body adjusts nicely.

    This is a super interesting TED Talk I found about intermittent fasting. Its from the perspective of a nurse practitioner and nutritionist. Its well worth a watch.

    How Can I Fast If I Work The Night Shift

    We recommend fasting through your shift and having your meals at home. Eat at home before you go to your night shift. While you work, use bone broth or coffee while you adjust. When you get off in the morning, have your breakfast at home and go to sleep. This way you get in 12 hours of fasting and avoid eating during the night when digestion is slowest. Another alternative is going to sleep immediately after you get home. When you wake up, have your first meal and eat again before your night shift.

    But Dont I Enter A State Of Starvation When Fasting

    What To Eat On One Meal A Day

    You may hear some health professionals state things like, fasting is the same as starving yourself, and I never consider starving a good behavior to adapt to unless you have no food to eat.

    However, to enter starvation mode actually takes a long time. Im talking about days

    Therefore, this shouldnt be a reason to not try intermittent fasting.

    My take away is that skipping meals at random can be dangerous because your body becomes used to a particular routine and glucose hit.

    But skipping meals as part of a structured approach, such as intermittent fasting is completely safe.

    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 significant stretches of time between meals force the body to use the fat stored in cells for energy, according to Harvard Health. Insulin levels decline through this process as the body burns fat.

    Lowden believes that any weight loss really comes down to 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 that study participants took in about 300 fewer calories per day when participating in the 16:8 approach to IF. The National Institute on Aging notes that IF may work because theres less time for eating, so you naturally take in fewer calories each day.

    Versions of IF that restrict eating after a certain time, say 7 p.m., also 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.

    Can You Have A Midnight Snack And Forget Breakfast

    With our goal of creating a 12-hour window of no eating, you might be wondering if you can eat until bedtime, and then skip breakfast.

    The research so far indicates that this might be possible, but if weight loss is your goal, you might be shooting yourself in the foot.

    Your defenses are down at night, which makes it more likely that your food choices will be high calorie, low-nutrient snack foods.

    Late-night eating also goes against your bodys natural fat-burning cycle, so youre more likely to store fat than to burn it.
