How Much Weight Can Be Lost With Intermittent Fasting
INTERMITTENT FASTING is an eating pattern that involves regular, short-term fasts or periods of minimal or no food consumption. Intermittent fasting deals with when to eat as it does not talk about what to eat and here you only eat at a specific time.
It works by prolonging the period when your body has burned through the calories consumed during your last meal and begins burning fat.
Most people use Intermittent fasting as a weight loss intervention but Intermittent fasting can also help improve risk factors for health conditions like diabetes and cardiovascular diseases such as lowering blood pressure and blood sugar.
Many intermittent fasting techniques exist and some of the methods include the 16:8,5:2 diet, warrior diet, eat stop eat, and alternate-day fasting.
All the methods are effective but figuring out which one works depends on the individual. Limiting the number of hours you can eat during the day may help you lose weight and lower your blood pressure.
Can Be A Sustainable Lifestyle Change
Intermittent fasting might sound complicated and intimidating, but it can be simple at times. In fact, you might even find that fasting helps simplify your day since you need to plan fewer meals.
Whats more, it doesnt typically require calorie counting, watching your macros, eating certain foods that you might not be used to eating, or eliminating certain foods that you otherwise enjoy.
For example, having an early dinner followed by a late breakfast the next day is one way to fast intermittently. If you finish your last meal at 8 p.m. and dont eat until noon the next day, youve technically fasted for 16 hours.
For people who get hungry in the morning and like to eat breakfast, or for those who cant eat until later in the evening due to work schedules and other obligations, this method may be hard to get used to.
However, other people instinctively eat this way already. They may be more prone to trying out an intermittent fasting eating pattern.
How To Do The : 8 Diet Correctly
In a June 2018 study published in Nutrition and Healthy Aging, researchers worked with 23 obese individuals with an average body mass index of 35. For a period of 12 weeks, the participants ate whatever they wanted between the hours of 10 am and 6 pm. But in the hours both before and after that specific timeframe, they only consumed water and calorie-free beverages. When compared to a matched historical control group from a previous weight loss trial, researchers discovered that this new group of people following the time-restricted eating schedule consumed fewer calories, lost weight, and reduced their blood pressure.
On average, participants ate about 350 fewer calories, lost approximately three percent of their body weight, and decreased their systolic blood pressure by about seven millimeters of mercury . And those benefits of intermittent fasting happened after just 12 weeks!
The take-home message from this study is that there are options for weight loss that do not include calorie counting or eliminating certain foods, said Krista Varady, PhD in a press release.
As tempting as it might be to fill those feasting hours with cookies, cake, and ice cream, you will probably get much better results if you opt for mostly healthy and whole foods. And remember, always get your doctors OK before starting a new diet.

- Levels of Human Growth Hormone increase dramatically: This can positively affect muscle growth.
- Mental acuity and cognition improve: This happens as less blood flow surges to the stomach to digest recently consumed food.
- Energy levels increase: As the body uses stored glycogen for energy.

Side Effects Of Intermittent Fasting
Intermittent fasting can have unpleasant side effects. They could include hunger, fatigue, insomnia, irritability, decreased concentration, nausea, constipation and headaches. Most side effects go away within a month.
Sticking with an intermittent fasting routine can be easier for some people rather than trying to watch calories every day. Other people, especially those with busy or variable schedules, have more difficulty maintaining an intermittent fasting routine.
The Benefits Of Intermittent Fasting
Fat loss is great, but it isn’t the only benefit of fasting.
1. Intermittent fasting makes your day simpler.
I’m big on behavior change, simplicity, and reducing stress. Intermittent fasting provides additional simplicity to my life that I really enjoy. When I wake up, I don’t worry about breakfast. I just grab a glass of water and start my day.
I enjoy eating and I don’t mind cooking, so eating three meals a day was never a hassle for me. However, intermittent fasting allows me to eat one less meal, which also means planning one less meal, cooking one less meal, and stressing about one less meal. It makes life a bit simpler and I like that.
2. Intermittent fasting helps you live longer.
Scientists have long known that restricting calories is a way of lengthening life. From a logical standpoint, this makes sense. When youre starving, your body finds ways to extend your life.
Theres just one problem: who wants to starve themselves in the name of living longer?
I dont know about you, but Im interested in enjoying a long life. Starving myself doesnt sound that appetizing.
The good news is that intermittent fasting activates many of the same mechanisms for extending life as calorie restriction. In other words, you get the benefits of a longer life without the hassle of starving.
Way back in 1945 it was discovered that intermittent fasting extended life in mice. More recently, this study found that alternate day intermittent fasting led to longer lifespans.

The Benefits Of Fasting Don’t Kick In At The Same Time For Every Person
Experts agree that your personal habits will play a role in when exactly certain health benefits will kick in.
“There are very few definites here,” says Vincent Pedre, M.D., an integrative physician and gut health expert who frequently recommends intermittent fasting diets to his patients.
“Where you start seeing those benefits depends on what you eat, how healthy your gut health is, what kind of physical activity you’re doing, etc.”
For example, letting calories slip into your fasting window, overeating calorie-dense foods like pizza during your eating window, not prioritizing sleep or physical activity, or making one of these intermittent-fasting mistakes could all delay or counteract the benefits of intermittent fasting.
Even if you’re formulating the rest of your diet and lifestyle perfectly, it’s important to understand that the different health benefits associated with intermittent fasting will likely kick in at different durations of fasting.
For example, weight loss may be triggered by a relatively short fasting window, while entering ketosis or triggering autophagythat “self-cleaning” cellular process that boosts brain functioning and maybe even longevitymay take significantly longer.
Unfortunately, not enough research has been conducted on all the different forms of intermittent fasting to provide any hard-and-fast rules.
How Does An Intermittent Fast Burn Fat
Assuming youve never gone on an intermittent fast before, you may be fascinated with how this works. How does the body burn fat while fasting? Is it simply by calorie restriction alone?
Actually, no. To understand how your body torches fat, we first have to talk about the bodys energy source.
From the moment you wake up until when you go to sleep , your body needs energy. This is what allows you to get up, go about your daily routine, and enjoy your life rather than feel like youre dragging through it.
This energy comes from glycogen, a polysaccharide of glucose. Bacteria, fungi, animals, and humans alike all rely on glycogen to fuel our daily activities. When our systems receive glucose, a simple sugar, we can synthesize it to glycogen for energy through glycogenesis.
Where does glucose come from? Mostly in the foods we eat. The foods with the highest quantities of glucose are fats, proteins, and carbohydrates. Thus, if you eat a diet rich with olive oil, avocados, peanut butter, cheese, meat, fish, dairy, fruits and vegetables, pasta, rice, and bread, you get plenty of glucose.
If your body has more glucose than it needs, it holds onto it for later. This can increase your insulin, meaning your body will always burn glucose, even if given the chance to burn fat instead. Should you develop an insulin resistance and this becomes chronic, your body increases insulin production when youre full.

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.
Safety And Side Effects
Hunger is the main side effect of intermittent fasting.
You may also feel weak and your brain may not perform as well as youre used to.
This may only be temporary, as it can take some time for your body to adapt to the new meal schedule.
If you have a medical condition, you should consult with your doctor before trying intermittent fasting.
This is particularly important if you:
- Have a history of eating disorders.
- Are a woman who is trying to conceive.
- Are a woman with a history of amenorrhea.
- Are pregnant or breastfeeding.
All that being said, intermittent fasting has an outstanding safety profile. There is nothing dangerous about not eating for a while if youre healthy and well-nourished overall.
The most common side effect of intermittent fasting is hunger. People with certain medical conditions should not fast without consulting with a doctor first.
Here are answers to the most common questions about intermittent fasting.

What Is 16/8 Intermittent Fasting
The practice of 16/8 intermittent fasting involves limiting your intake of foods and calorie-containing beverages to a set window of 8 hours per day. You abstain from food for the remaining 16 hours, though youre still allowed to drink water and other no-calorie beverages, like plain coffee or tea.
You can repeat this cycle as frequently as youd like from just once or twice per week to every day, depending on your preference.
The popularity of this fasting method has grown widely among those looking to lose weight and burn fat. 16/8 intermittent fasting is also believed to improve blood sugar control and enhance longevity.

Metabolic Flexibility The Key
After youve done a proper 21 day reset, the end result should be that youre now metabolically flexible.
Youre now fat adapted and you can easily switch fuel sources from the foods that you eat to your own body fat for energy. Thats when you get into what I like to call accelerated fat loss.
If you dont do a proper reset, and you still follow a standard western diet and you just jump in with intermittent fasting, that is the definition of metabolic inflexibility. And youre not going to see the results youre looking for.
This is where a lot of people find themselves. This is where you hear people say that they got headaches from fasting, they were starving the entire time, they didnt feel good, and they say it didnt work for them.
Yeah, no kidding. I couldve told you that.
Now the people whos taken the proper 21 day primal reset inside the Fat Loss Accelerator have all successfully unregulated their fat burning metabolism. Theyre metabolically flexible and they can easily fast for long periods of time without feeling hungry.
Which means that theyre able to burn more fat. Theyve also all been successful at being able to keep the weight off.
Now, how long will it take for you to start seeing results? It really depends how long you fast for, and how often. I always like to say that the longer you fast, the better.
So if youve been overweight for a long time, that means that youve also been insulin resistant for a long time.

So How Does If Work For Weight Loss Exactly
Intermittent fasting is about when you eat, says Charlotte Martin, MS, RDN, CPT, owner of Shaped by Charlotte, LLC. Depending on the IF approach, youre either shortening the eating window each day, or engaging in about 24-hour fasts one or more times a week. One of the most popular approaches is the 16:8 method, which is when you fast for an 16-hour window, like from 8 p.m. to 12 p.m. the next day.

Essentially, by restricting your food intake to a shortened time window, you naturally decrease your caloric intake and, in turn, can lose weight. “Not only are you taking in fewer calories, but youre also slowing down your insulin pump, which may boost fat burn,” explains Martin.
Figure Out Calorie Needs
There are no inherent dietary restrictions when intermittent fasting, but this does not mean that calories do not count.
People who are working with a doctor or dietitian to manage their weight need to create a calorie deficit, which means consuming fewer calories than they use. People who are looking to gain weight need to consume more calories than they use.
Many tools are available to help a person work out their calorie needs and determine how many calories they should consume each day to gain, lose, or maintain weight.
A person could also consult a healthcare professional or dietitian for guidance on how many calories they need. A professional can help a person determine the best foods for them and find an overall healthy way to lose weight.

Figure Out A Meal Plan
A person interested in losing or gaining weight may find it helpful to plan what they are going to eat during the day or week.
Meal planning does not need to be overly restrictive. It considers calorie intake and incorporating proper nutrients into the diet. For example, the Centers for Disease Control and Prevention recommends the MyPlatePlan, which focuses on showing a person food group targets for each day.
Meal planning offers many benefits, such as helping a person stick to their calorie count and ensuring they have the necessary ingredients on hand for recipes, quick meals, and snacks. As a potential bonus, meal planning could save money if it helps people waste less food.
Not all calories are the same. Although these fasting methods do not limit the number of calories a person consumes during eating periods, it is essential to consider the nutritional value of the food.
In general, a person should aim to consume nutrient-dense foods, or foods with a
- 2018 review of studies , calorie restriction and intermittent fasting can help the body activate a healing process called autophagy, which essentially means that the body digests or recycles old or damaged cell components.
Fasting dates back to ancient humans, who often went hours or days between meals because obtaining food was difficult. The human body adapted to this style of eating, allowing extended periods to pass between food intake times.
Research also suggests that fasting has a variety of other benefits.
