How Does Intermittent Fasting Work
There are several different ways to do intermittent fasting, but they are all based on choosing regular time periods to eat and fast. For instance, you might try eating only during an eight-hour period each day and fast for the remainder. Or you might choose to eat only one meal a day two days a week. There are many different intermittent fasting schedules.
Mattson says that after hours without food, the body exhausts its sugar stores and starts burning fat. He refers to this as metabolic switching.
Intermittent fasting contrasts with the normal eating pattern for most Americans, who eat throughout their waking hours, Mattson says. If someone is eating three meals a day, plus snacks, and theyre not exercising, then every time they eat, theyre running on those calories and not burning their fat stores.
Intermittent fasting works by prolonging the period when your body has burned through the calories consumed during your last meal and begins burning fat.
Intermittent Fasting 16/8 Vs 20/: Which One Should You Try
If you are a beginner, the 16/8 method would be better for you than jumping headfirst into the intermittent fasting 20/4 method. Unlike the latter, the former gives you less time to fast, translating into a longer feeding window. Once your body gets used to the 16:8 variation, then you could choose to attempt a 20/4 intermittent fasting meal plan.
What Does Intermittent Fasting Mean
Intermittent fasting is an eating plan that switches between fasting and eating on a regular schedule. It involves a pattern where you cycle between periods of eating and fasting. It is also an umbrella term for various meal timing schedules that cycle between voluntary fasting and non fasting over a given period.
Intermittent fasting does not say anything about which foods to eat but rather deals with when you should eat them.
There are several different fasting methods, all of which split the day or week into eating periods and fasting periods. Going without food for a number of hours each day or taking just one meal a couple of days a week can help your body burn fat.
Research shows that there are several evidence of benefits as Intermittent fasting is a way to manage your weight and prevent certain health problems like obesity, insulin resistance, dyslipidemia, hypertension, and inflammation.

May Help With Inflammation
Some types of intermittent fasting have been associated with a decrease in chronic inflammation . While this research did not involve the intermittent fasting 20/4 method, you may still reap the same benefits. Excess inflammation can lead to illnesses such as heart disease, diabetes, some cancers, bowel disorders, and more.
How Do Fasting Diets Work To Help Rev Weight Loss
The idea behind intermittent fasting is that it increases your metabolic rate, which helps you burn more calories. And by restricting the time periods during the day when you eat, you take in fewer calories each day.
Going into diet change, I knew there was only early evidence that fasting can lead to temporary weight loss, and that more research is needed especially on the potential long-term health effects of this diet.; As it stands, experts warn that fasting may not be safe, or smart, for everyone. Fasting is not recommended for some groups, such as pregnant or lactating women, some people with diabetes, people dealing with eating disorders or issues such as low blood sugar, according to the Mayo Clinic. Thats why experts stress that its important to consult your healthcare team before trying any type of fast.
Despite the lack of comprehensive research on intermittent fasting, this eating style has helped me lose weight, regain my energy, and become more mindful about my eating choices.

Reason : Youre Not Fasting Long Enough
If youre not seeing results, it could be that you arent fasting long enough for your body.
Try ramping up the duration of your fasting window.
While its possible to lose weight fasting as little as 12 hours at a time, try increasing your fasting window if your weight loss has stalled.
A fasting period of 14-16 hours seems to work best for most people.
Double-check that youre not actually breaking your fast too early.
If you find that you are, try extending your fasting period a bit at a time until you can hit that 14-16 hour window.
Extend your fasting window to at least 14-16 hours if your weight loss has stalled.
So Is Intermittent Fasting As Good As It Sounds
I was very curious about this, so I asked the opinion of metabolic expert Dr. Deborah Wexler, Director of the Massachusetts General Hospital Diabetes Center and associate professor at Harvard Medical School. Here is what she told me. “There is evidence to suggest that the circadian rhythm fasting approach, where meals are restricted to an eight to 10-hour period of the daytime, is effective,” she confirmed, though generally she recommends that people “use an eating approach that works for them and is sustainable to them.”
So, heres the deal. There is some good scientific evidence suggesting that circadian rhythm fasting, when combined with a healthy diet and lifestyle, can be a particularly effective approach to weight loss, especially for people at risk for diabetes.

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.

Weight Loss And Fat Loss
Eating during a set period can help people reduce the number of calories that they consume. It may also help boost metabolism.
A 2017 study suggests that intermittent fasting leads to greater weight loss and fat loss in men with obesity than regular calorie restriction.
Research from 2016 reports that men who followed a 16:8 approach for 8 weeks while resistance training showed a decrease in fat mass. The participants maintained their muscle mass throughout.
In contrast, a 2017 study found very little difference in weight loss between participants who practiced intermittent fasting in the form of alternate-day fasting rather than 16:8 fasting and those who reduced their overall calorie intake. The dropout rate was also high among those in the intermittent fasting group.

How Many Hours/days Per Week You Fast
Losing weight is all about eating fewer calories than what your body uses. When youre fasting, youre avoiding food and caloric beverages. Some fasts allow you to eat, but usually, this is a meager amount. Take, for example, the 5:2 diet. During your two fasting days a week, you can consume no more than 600 calories.
On an alternate-day fast, you ingest no calories for the 24 hours in which you fast. Depending on how you arrange your calendar, you might fast for three or four days per week, foregoing calories for 72 to 96 hours.

How Does Intermittent Fasting Work For Weight Loss
Intermittent fasting was working perfectly for me, and it was easy to follow. I began to think more deeply about why it was working. Was my body changing because I was fasting for those 16 hours each day, or was it simply a trick I was playing on my mind to eat fewer calories? And if it was a trick, would my mind eventually figure it out?
In general, I think intermittent fasting helps people get more in touch with their needs, Varady says. Weve become accustomed to eating or drinking something every couple of hours. Wed never even noticed when were actually hungry or full. So when you go for longer stretches of time without eating, all of a sudden, your body becomes more attuned to it.
In my case, intermittent fasting made me more aware of my tendency to emotionally eat. Getting up early to get my young son to school, it wasnt as if I wanted to have that bagel and soda. I felt I needed that sugar rush to wake me up and get me going. Exercise replaced that without my needing to ride a sugar roller coaster every day.

Recommended Foods And Tips
While the 16:8 intermittent fasting plan does not specify which foods to eat and avoid, it is beneficial to focus on healthful eating and to limit or avoid junk foods. The consumption of too much unhealthful food may cause weight gain and contribute to disease.
A balanced diet focuses primarily on:
- fruits and vegetables, which can be fresh, frozen, or canned
- whole grains, including quinoa, brown rice, oats, and barley
- lean protein sources, such as poultry, fish, beans, lentils, tofu, nuts, seeds, low fat cottage cheese, and eggs
- healthful fats from fatty fish, olives, olive oil, coconuts, avocados, nuts, and seeds
Fruits, vegetables, and whole grains are high in fiber, so they can help keep a person feeling full and satisfied. Healthful fats and proteins can also contribute to satiety.
Beverages can play a role in satiety for those following the 16:8 intermittent fasting diet. Drinking water regularly throughout the day can help reduce calorie intake because people often mistake thirst for hunger.
The 16:8 diet plan permits the consumption of calorie-free drinks such as water and unsweetened tea and coffee during the 16-hour fasting window. It is important to consume fluids regularly to avoid dehydration.

Why You May Not See Results
Although there is research supporting the effectiveness of intermittent fasting, there are many reasons; you may not see results. It may sound counter-intuitive, but you may not be eating enough calories during your fasting window. If you severely restrict calories, it can backfire. Sudden under-consumption can lead to metabolic adaptation, a process where your body becomes more efficient at using energy and storing fat which means youll burn less calories. The goal is not to count calories and cut them, its to eat minimally processed, nutritious foods during your eating window until you are full.;
If you eat ultra-processed, energy-dense foods during your meals, that could be another reason why youre not getting the results you desire. Fasting can help you burn fat, but it doesnt mean that its magic! Remember to fill your plate with lean proteins, complex carbs, and healthy fats.;
Finally, make sure you drink plenty of water during your fasting window. Hydration helps you feel full and satiated, and its easy to mistake thirst for hunger. If youre not hydrated when you approach your eating window, you may be prone to choose and eat ultra-processed foods.;
