2.Now the second way that intermittent fasting can help certain individuals burnfat faster
Then they would with regular continuous calorie restriction is because it reduces the number of calories that you eat on a daily basis without reducing the size fullness and quality of your meals.
When youre eating 5 or 6 times a day and youre trying to stay in a calorie deficit to burn fat your meals wind up being tiny.
This could lead to a very unsatisfying experience every time you eat.
If your meals start looking like one brown rice cake with half a tablespoon of peanut butter and only 3 almonds its easy to see how eating can quickly
become more of a chore with no satisfaction rather than something that you actually enjoy.
If you hate your diet youre not going to stick to it and it doesnt matter how good the diet looks on paper if you dont stick to it youre not going to lose any inches off your waist.
This is where intermittent fasting presents an Advantage for many people. By only eating once or twice a day you can have much larger and more filling meals
that leave you satisfied and you can choose from a larger selection of options that would normally be unavailable in the continuous calorie restriction model
because those options may contain too many calories to balance out with 5 other meals.
this is highly dependent on personal preference but for a large group of people including myself, it can make dieting much easier.
Which Intermittent Fasting Type Works Best For Each Body Type
Certain body types react better to types of intermittent fasting and to pinpoint your exact type and body shape, we have outlined some of the most effective intermittent fasting diets for each of the three body types.
And while there is no specific research to pinpoint one intermittent fasting plan over another, these recommendations are chosen based on body type consideration and propensity for fat loss.
To 24 Hours After Your Last Meal
Given blood sugar levels get too low, the body starts to break down glycogen stores in the liver and muscles to produce glucose, which is needed to maintain your blood sugar, which is required by the brain. Your body also starts to break down fats into free fatty acids that enter your bloodstream to provide an alternative source of energy to glucose.

What Can I Drink While Fasting
You can drink anything that doesnt have calories! Ideally, also avoid beverages sweetened with artificial sweeteners, as these can impact your metabolism through your gut microbes. Some artificial sweeteners raise your insulin levels more than others , but theres a connection between many artificial sweeteners and negative gut microbe changes, insulin resistance and metabolic disease. While a recent meta-analysis suggests we need further research, it may be best to avoid sucralose, aspartame and saccharin in general.
While fasting, you can drink things like black coffee, unsweetened hot and cold teas, water with added electrolytes, carbonated water, water with lemon, etc. Learn more about what you can drink while fasting here.
If you are feeling like you need a little pick-me-up during a longer fast, you can enjoy some bone broth, some kombucha tea or other beverages with very small amounts of natural flavorings or healthy fats added. For example, you might enjoy some coffee with a little bit of butter or coconut oil added.
Reduces The Risk Of Diabetes And Heart Disease
As you lose weight and lower your blood pressure, the body necessarily responds with lower risks of diabetes, heart disease, or a related metabolic syndrome.
In fact, studies suggest that intermittent fasting is particularly effective in preventing cardiovascular issues by lowering cholesterol and improving the bodys responses to oxidative stress.

Daily Calorie Restriction Slows Down Your Metabolism
Another problem with just cutting calories is that it usually slows down your metabolism.
Heres a typical scenario
Lets say you normally eat 2000 calories a day. But youre overweight, so you decide to cut it down to 1,500 calories per day.
At first, you lose some weight. But pretty soon your body realizes there are only 1,500 calories coming in every day. So obviously it has to make an adjustment, or after a while you would starve to death.
Since youre only eating 1,500 calories per day, your body gradually shifts down to only burning 1,500 calories each day. In other words, it slows down your metabolism.
And your weight loss plateaus.
As a bonus, you feel crappy and fatigued, because you dont have as much energy as you used to. So you probably give up on your diet.
With your now-slower metabolism, your weight quickly rebounds as well.
In a nutshell, thats why most calorie-restriction diets fail, and may even do more harm than good.
How To Lose Weight By Fasting: The 1: 8 Diet
The 16:8 diet is one of the most popular ways of intermittent fasting. Its extremely simple: for 16 hours you fast, avoiding food and any calorie-containing beverages, and then once those 16 hours are up, you eat your meals within a specific eight-hour eating window.
The great thing about this method is that you can choose any eight-hour window that suits your lifestyle. Plus, your 16 hours of non-eating can incorporate sleep time. For example, you could stop eating at 8pm and wait until noon the next day to open your eating window again. Or if you prefer an earlier breakfast you could opt for a 9am to 5pm eating schedule.
A downside of the 16:8 diet is that it may take your body some time to adjust to eating more meals within a shorter time frame. One workaround is to limit your eating to two meals a day, but initially, you may wish to start with three meals spread out over the course of the eight hours.
Research from the journal Nutrients suggests that intermittent fasting methods like the 16:8 diet can help lower high blood pressure, reduce the amount of food consumed and ultimately lead to weight loss. And for those worried about losing muscle, the 16:8 diet can help maintain muscle mass and prevent muscle loss when combined with resistance training, according to studies in the Journal of Translational Medicine and the American Journal of Clinical Nutrition .

How To Lose Weight By Fasting: The : 2 Diet
Following the 5:2 diet involves five ‘regular days’ where there is no restriction on food intake followed by two days of eating a maximum of 500-600 calories each day . Research shows that many people find this type of fasting easier to follow, and there is a degree of flexibility as you can choose whichever two days of the week you prefer as your fast days, provided there is at least one day of eating between them.
On both your regular eating and lower calorie days, is important to make sure that your meals are healthy and nutritious. Many proponents of the 5:2 recommend soups for your restricted eating days as studies in the journal Appetite have shown that they may help make you feel fuller for longer.
The main benefit of the 5:2 diet is the reduced calorie intake on fasting days. In one 50-week study that involved 150 participants following the 5:2 diet, researchers found that this method of intermittent fasting was as effective as traditional dieting for weight loss, and another study in the International Journal of Obesity showed the 5:2 diet to be very effective at reducing insulin levels.
One downside is that if the 500-600 calories are consumed throughout the day, as opposed to one sitting, fat loss might be less substantial and take longer than following a frequent 16:8 diet regime.
Intermittent Fasting For Healthy Weight Loss
As weve said, not all weight loss is the same. Its essential to make sure youre losing weight in a healthy way. Can intermittent fasting help with healthy weight loss?
Here, the data are conflicting.
On one hand, intermittent fasting can help improve metabolic health by reducing blood sugar and blood pressure while also improving blood lipid levels.4
On the other hand, two trials suggested that intermittent fasting may not lead to greater weight loss than usual care, or even worse may lead to greater loss of lean muscle mass than usual care or continuous calorie restriction.5
A healthy weight loss intervention also should be relatively easy to comply with and maintain long-term. Fortunately, intermittent fasting may fit that criteria.
One study reported that working adults found time-restricted eating with an eight-hour eating window easy to comply with and maintain for three months.6
That fits with frequent clinical experience suggesting many people easily adapt to time-restricted eating, especially when they follow a low-carb or high-protein diet that helps improve satiety and reduce appetite.7
So, in terms of convenience and ease in your approach to healthy weight loss, intermittent fasting seems to be a winner.

The : 2 Fasting Method Is Suitable For Those Looking For An Easier Approach To Fasting
“The 5:2 fasting method requires a person to fast for two non-consecutive days per week,” Yule told INSIDER. On fasting days, she said a person consumes no more than 500 to 600 calories. A person might choose this type of fast because it is easier in the sense that they only have to be restrictive once or twice a week, she added.
Yule explained, however, that a major con to the 5:2 fasting method is that it might be very difficult to maintain over the long-term. “The person may feel fatigued, hungry, or irritable on the days that they are consuming so little food, and that could make the workday unpleasant,” she said.
How Do I Know If My Body Is Ready For Intermittent Fasts
Your body has an innate timing system that lets you know when it is time for a change. When you feel exhausted and uninterested in any work that needs to be done, then its best to stop eating for a while. Of course, you should take a day off after 2 or 3 weeks of fasting. This will help your body stay fresh and active.

Benefits Of Intermittent Fasting
Can intermittent fasting improve your health? Recent research has found that using intermittent fasting for weight loss may have some benefits in the short term.
It appears that fasting for a short time can produce ketosis, which is a process that occurs when the body doesn’t have enough glucose for energy, so it breaks down stored fat instead. This causes an increase in substances called ketones. This, coupled with fewer calories consumed overall, can lead to weight loss. Research suggests that alternate-day fasting is about as effective as a typical low-calorie diet for weight loss.
Fasting also affects metabolic processes in the body that may work to decrease inflammation, as well as improve blood sugar regulation and physical stress response. Some research shows this may improve conditions associated with inflammation like arthritis, asthma and multiple sclerosis.
Little long-term research has been done on intermittent fasting to examine how it affects people over time. As a result, long-term health benefits or risks are unknown.
Diet May Be The Best For Endomorphs
Finally, the endomorph body type typically comes across as curvy and tends to hold body fat in the stomach, thigh, and hip areas.
This body type tends to struggle with how to lose weight as an endomorph and might find intermittent fasting the most beneficial of the other body types.
The 5:2 diet is one of the easiest to work into your schedule, as it requires you to fast for two non-consecutive days under 500-600 calories, and then eat normally for the rest of the week.
Plus, it lets you still be physically active on non-fasting days for strength training and further weight loss!
Two other options for the endomorph body type include a 24-hour fast and the Warrior Diet. Both diets require longer periods of fasting to lower fat stores more effectively, with abstaining from calories for a whole day during a 24-hour fast, and restricting calories for 20 hours of the day for the Warrior Diet.
Because of this greater deficit, how to lose weight as an endomorph means your metabolism needs to spring into high gear and lose body fat quite quickly, which is ideal for this body type.

Examples Of Different Intermittent Fasting Schedules
If youre considering giving fasting a shot, there are a few different options for working it into your lifestyle.
Daily Intermittent Fasting
Most of the time, I follow the Leangains model of intermittent fasting, which uses a 16hour fast followed by an 8hour eating period. This model of daily intermittent fasting was popularized by Martin Berkhan of Leangains.com, which is where the name originated.
It doesn’t matter when you start your 8hour eating period. You can start at 8am and stop at 4pm. Or you start at 2pm and stop at 10pm. Do whatever works for you. I tend to find that eating around 1pm and 8pm works well because those times allow me to eat lunch and dinner with friends and family. Breakfast is typically a meal that I eat on my own, so skipping it isn’t a big deal.
Because daily intermittent fasting is done every day it becomes very easy to get into the habit of eating on this schedule. Right now, you’re probably eating around the same time every day without thinking about it. Well, with daily intermittent fasting it’s the same thing, you just learn to not eat at certain times, which is remarkably easy.
Weekly Intermittent Fasting
One of the best ways to get started with intermittent fasting is to do it once per week or once per month. The occasional fast has been shown to lead to many of the benefits of fasting we’ve already talked about, so even if you don’t use it to cut down on calories consistently there are still many other health benefits of fasting.

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.
