The 5 Stages Of Intermittent And Prolonged Fasting

A Rookie

Cahill conceptualized his fasting stages according to which energy source the body is predominantly using at any given time .

He distinguishes between two primary fuel sources:

  • Glucose: a carbohydrate and sugar
  • Triglycerides: stored body fat

While most cells can use both energy sources, the brain is an exception because it cannot use triglycerides.

Other cells, such as those in the liver, kidneys, muscles, or heart, can use both energy sources.

While the body stores fat as triglycerides, carbohydrates are stored in the form of glycogen.

This molecule consists of glucose chains and water. Glycogen is stored primarily in the liver and partially in skeletal muscle.

As soon as the body needs blood sugar, it splits the molecule into smaller glucose molecules and relieves them into the bloodstream.

When glycogen is no longer available, the body must draw on fat reserves. For this purpose, triglycerides from the fat cells enter the liver, where they are broken down.

In addition to fatty acid chains, glycerol is produced, which your body can convert into glucose for the brain.

Firing Up The Fat Burning Furnace

As mentioned before the body starts to burn fat when the glycogen supply is depleted after about six to eight hours, but on top of that, intermittent fasting will also help spice up the metabolism.

Restricting the time period, during which you eat, makes your body burn more calories throughout the day. Because the longer you feed, the lazier your metabolism becomes. But fit your food intake into an 8-hour window and your body steps up to the plate, burning more calories day and night.

Leptin, the hormone that regulates fat storage as well as hunger signals, and ghrelin, another hormone that tells your brain the body is hungry, are also normalized by routine fasting.

Leptin is produced by fat cells and works by telling the brain to turn off hunger signals when body fat levels are sufficient for survival and reproduction.

Intermittent Fasting Can Be Hard But Maybe It Doesnt Have To Be

Initial human studies that compared fasting every other day to eating less every day showed that both worked about equally for weight loss, though people struggled with the fasting days. So, I had written off IF as no better or worse than simply eating less, only far more uncomfortable. My advice was to just stick with the sensible, , diet.

New research is suggesting that not all IF approaches are the same, and some are actually very reasonable, effective, and sustainable, especially when combined with a nutritious plant-based diet. So Im prepared to take my lumps on this one .

We have evolved to be in sync with the day/night cycle, i.e., a circadian rhythm. Our metabolism has adapted to daytime food, nighttime sleep. Nighttime eating is well associated with a higher risk of obesity, as well as .

Based on this, researchers from the University of Alabama conducted a study with a small group of obese men with prediabetes. They compared a form of intermittent fasting called “early time-restricted feeding,” where all meals were fit into an early eight-hour period of the day ,or spread out over 12 hours . Both groups maintained their weight but after five weeks, the eight-hours group had dramatically lower insulin levels and significantly improved insulin sensitivity, as well as significantly lower blood pressure. The best part? The eight-hours group also had significantly decreased appetite. They werent starving.

6 Popular Ways to Do Intermittent Fasting

14:10 is a type of intermittent fasting.

During the feeding period, you can eat your usual meals and snacks. Likewise, during the fasting window, you are not allowed to eat any calories. However, you can drink water and unsweetened coffee or green tea.

If You Need To Lose Weight A Diet That Focuses Mainly On When You Eat May Be A Good Way To Shed Pounds And Improve Your Cardiovascular Health

Anyone who’s tried different weight-lossdiets is probably familiar with their pitfalls. Low-calorie diets often leave you tired, hungry, and cranky. Low-carb or “keto” diets can cause cravings and constipation. Low-fat diets are also tough to follow and, contrary to popular belief, they do not seem to prevent cardiovascular disease.

Another diet trend, intermittent fasting, takes a different approach. Rather than limiting what you eat, this diet limits when you eat . For some people, that change may be easier to manage, says Dr. Eric Rimm, professor of epidemiology and nutrition at the Harvard T.H. Chan School of Public Health.

Short-term studies suggest that people stick to intermittent fasting diets as well as or better than they do to other diets. And according to a 2019 review article in the journal Nutrients, intermittent fasting promotes weight loss and may reduce risk factors linked to heart disease, including diabetes, high blood pressure, unhealthy blood lipid levels, and inflammation.

“However, we don’t have much evidence about how well this diet works over the long term,” says Dr. Rimm, noting that there are just two long-term studies of intermittent fasting, each lasting a year. Nor are there large populations of people who’ve followed this eating pattern for years. That’s in contrast to two other diets linked to a healthy heart and healthy body size the Mediterranean diet and a vegetarian diet.

Is 16/8 Intermittent Fasting Right For You

16/8 intermittent fasting can be a sustainable, safe and easy way to improve your health when paired with a nutritious diet and a healthy lifestyle.

However, it shouldnt be viewed as a substitute for a balanced, well-rounded diet rich in whole foods. Not to mention, you can still be healthy even if intermittent fasting doesnt work for you.

Though 16/8 intermittent fasting is generally considered safe for most healthy adults, you should talk to your doctor before giving it a try, especially if you have any underlying health conditions.

This is key if youre taking any medications or have diabetes, low blood pressure or a history of disordered eating.

Intermittent fasting is also not recommended for women who are trying to conceive or those who are pregnant or breastfeeding.

If you have any concerns or experience any adverse side effects while fasting, be sure to consult your doctor.

16/8 intermittent fasting involves eating only during an 8-hour window and fasting for the remaining 16 hours.

It may support weight loss and improve blood sugar, brain function and longevity.

Eat a healthy diet during your eating period and drink calorie-free beverages like water or unsweetened teas and coffee.

Its best to talk to your doctor before trying intermittent fasting, especially if you have any underlying health conditions.

Frequently Asked Questions Concerns And Complaints

The BEST Intermittent Fasting Schedule For Weight Loss

Im a woman. Should I do anything differently?

I havent worked with women on implementing an intermittent fasting schedule, so I cant speak from experience on this one.

That said, I have heard that women may find a wider window of eating to be more favorable when doing daily intermittent fasting. While men will typically fast for 16 hours and then eat for 8 hours, women may find better results by eating for 10 hours and fasting for 14 hours. The best advice I can give anyone, not just women, is to experiment and see what works best for you. Your body will give you signals. Follow what your body responds favorably to.

Also, if youre a female, there is an allfemale page on Facebook that discusses intermittent fasting. Im sure you could find a ton of great answers and support there.

I could never skip breakfast. How do you do it?

I dont. Breakfast foods are my favorite, so I just eat them at 1pm each day.

Also, if you eat a big dinner the night before, I think youll be surprised by how much energy you have in the morning. Most of the worries or concerns that people have about intermittent fasting are due to the fact that they have had it pounded into them by companies that they need to eat breakfast or they need to eat every three hours and so on. The science doesnt support it and neither do my personal experiences.

I thought you were supposed to eat every 3 hours?

Here’s why this was a popular idea for a brief period of time:

Women And Intermittent Fasting

Intermittent fasting can cause hormonal imbalance in women if its not done correctly . Women are extremely sensitive to signals of starvation, and if the body senses that it is being starved, it will ramp up production of the hunger hormones leptin and ghrelin.

So when women experience insatiable hunger after under-eating, they are actually experiencing the increased production of these hormones. Its the female bodys way of protecting a potential fetus even when a woman is not pregnant.

So women have to set cunningly about it. And if you do so, you can get all the benefits of fasting.

One study of healthy young women found that a 10-hour eating window had an anti-stress effect, lowering cortisol and increasing parasympathetic* activity .

*) The parasympathetic nervous system is the “brake” that causes the body to calm down, and which is active when we relax, sleep, eat and meditate.

So if you are a woman or trying fasting for the first time, you might benefit from modified or crescendo intermittent fasting.

This is a more gentle approach that helps the body more easily adapt to fasting. Not all women need crescendo fasting, but it will ensure success in most.

  • Fast on 23 non-consecutive days per week

  • On fasting days, do yoga or light cardio.

  • Ideally, fast for 1216 hours.

  • Eat normally on your strength training/HIIT workouts intense exercise days.

  • Drink plenty of water.

  • After two weeks, feel free to add one more day of fasting.

  • Listen to your body.

  • Weight Loss / Weight Management From Fasting

    In general it takes between 6 to 8 hours for the body to burn through its glycogen supply. When glycogen is depleted the body will then turn to the energy stored in fat cells.

    Eating throughout the day makes it much harder for the body to burn fat. Extending the time between eating with 12 hour intermittent fasting will force your body to tap into stored fat reserves.

    Tips For Intermittent Fasting

    • Increase the fluid intake a day or two before you start fasting.
    • Consume raw foods from vegetable and fruits to nuts etc. while avoiding processed foods, sugars, and dairy.
    • Initially fast for only a few hours, preferably during the morning as it helps the body to rev up for another day by eliminating the debris body might have collected while you slept.
    • Avoid taking any calorie-free drinks and beverages that use artificial sweeteners as they tend to stimulate your appetite just like any drink that contains sugar, which makes you overeat.
    • Avoid gorging at your first meal after the fast as binging will not only diminish the benefits of fast but also make you feel awful.

    10 Types of Intermittent Fasting: Which One Is For You ...

    Various methods of intermittent fasting, including 20-hour fasting cycles, have been linked to weight loss.

    One study, which closely mimicked the Warrior Diet , found that people who consumed meals over four hours in the evening experienced more weight loss than those who consumed the same amount of calories in meals throughout the day.

    Whats more, those who ate one meal per day showed significantly reduced fat mass and greater muscle mass .

    A recent review of six studies concluded that various types of intermittent fasting, ranging from 3 to 12 months, were more effective at promoting weight loss than no dietary intervention.

    However, the review found that there were no significant weight loss differences between dieters using intermittent fasting or continuous calorie restriction , meaning that calorie restriction without fasting was equally effective .

    Additionally, although reducing calorie intake is the most common outcome of the Warrior Diet, some people following this eating pattern could technically consume too many calories during the four-hour overeating period and experience weight gain.
