How To Calculate Intermittent Fasting

What Can I Eat

Calculating how many calories to eat to lose weight while intermittent fasting

The macros you should eat depend on your goals. There are many different ways you can tweak your macro ratios depending on what you hope to accomplish and what diet plan youre following.

For example, if youre following a Keto Diet, you may want to consume about 70% fat, 25% protein, and only 5% carbs.

If youre not sure what ratio of macros is right for you, dont worry.

Eat This Much has a macro calculator that does all the work for you!

Not only will it calculate the number of daily calories you should eat to lose weight, but it will also generate meal plans that balance your macros and even recipes to help you stay on track. Lets take a closer look at this top-rated tool for weight loss.

Alternate Day Fasting : 2 Method

Some people fast on alternate days to improve blood sugar, cholesterol, and weight loss. A person on the 5:2 method eats 500 to 600 calories on two non-consecutive days each week.

Some alternate-day fasting regimens add in a third day of fasting each week. For the rest of the week, a person eats only the number of calories they burn during the day. Over time, this creates a calorie deficit that allows the person to lose weight.

Resources on the Eat Stop Eat, Warrior, and Leangains fasting methods are available to purchase online.

My Intermittent Fasting Feeding Window:

Heres what I do and what may make your life simpler:

  • I fast for the first 4-6 hours after waking up
  • This allows for any days that I sleep in or wake up very early

Not every day is going to be the same.

As the saying goes, SH*T happens.

I think that if your schedule is sporadic, then you should follow what I do.

That being said, here is a sort of leangains calculator for finding your specific fasting period:

How many hours do you want to spend NOT eating?

This is your fasting period. NOT the hours you would spend eating throughout the day.

Remember, popular methods are:

8/16 method or Leangains method = 8 hours of eating / 16 hours of fasting

6/18 method = 6 hours of eating / 18 hours of fasting

This method is more aggressive but still popular

4/20 method = 4 hours of eating / 20 hours of fasting

This method is VERY aggressive and is not for everyone. I only recommend it if you need to lose weight quickly.

The 2nd result will be the amount of time you spend eating every day.

Now whether you chose to follow what I do or one of the popular methods explained before, you will adjust it to your schedule.

Some things that will influence your fasting window:

  • your eating pattern,
  • your macronutrient ratios,
  • and your weight loss program

Again, its your body and schedule. Spend time on this to make it work for you.

How Intermittent Fasting Works: Insulin Reduction Ketone Production And Autophagy Induction

From a weight-loss perspective, intermittent fasting works by making it harder to overeat throughout the day. A simple rule like skip breakfast or only eat between 5 pm and 8 pm, can help prevent you from reaching for snacks or drinking calorie-dense beverages throughout the day that contribute to weight gain.

Even if you do build up a ferocious appetite while fasting, youll still find it difficult to overeat. In fact, intermittent fasting tends to decrease daily energy consumption and promote fat loss.

This means that you may be able to eat as much as you want and reach your goals as long as you stick to a shortened eating window or a limited number of meals.

When you first try intermittent fasting, your body will need to adjust itself to this new eating schedule. You may be hit hard by hunger pangs and potent cravings at first, but they will soon dissipate as your cells feast on stored fat and ketones.

The key mechanisms behind your ability to fast, lose fat, and improve your health throughout the process are insulin reduction, ketone production, and autophagy. As we accumulate time in a fasted state, our insulin levels decrease incrementally. This promotes the release of fat from our fat cells and stimulates the ketone-producing process known as ketogenesis.

As you continue your fast, youll enter a deeper state of ketosis, become more efficient at burning fat, and ramp up the self-cleaning process known as autophagy.

What Is Macro Tracking

An Overview of Intermittent Fasting

Macro tracking refers to accounting for the macronutrients youre consuming on a daily basis. This concept is extremely popular in the fields of nutrition and fitness.

To get a sense of how to track your macros, we first need to tackle the major nutrients, which include:

  • Carbohydrates
  • Lipids
  • Protein

The primary goal of tracking your macros is to follow a ratio that allows you to reach a certain goal in as little time as possible.

Despite how simple the concept may seem, many people find macro tracking to be confusing, especially in the beginning.

Make The Calories Count

Not all calories are the same. Although these fasting methods do not set restrictions on how many calories a person should consume when fasting, it is essential to consider the nutritional value of the food.

In general, a person should aim to consume nutrient-dense food, or food with a high number of nutrients per calorie. Though a person may not have to abandon junk food entirely, they should still practice moderation and focus on more healthful options to gain the most benefits.

Fasting has several effects on a persons body. These effects include:

  • Reducing levels of insulin, which makes it easier for the body to use stored fat.
  • Lowering blood sugars, blood pressure, and inflammation levels.
  • Changing the expression of certain genes, which helps the body protect itself from disease as well as promoting longevity.
  • Dramatically increases human growth hormone, or HGH, which helps the body utilize body fat and grow muscle.
  • The body activates a healing process doctors call 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 as obtaining food was difficult. The human body adapted to this style of eating, allowing extended periods to pass between food intake times.

Research also shows fasting to be beneficial for the management of metabolic syndrome and diabetes, extending lifespan,

Intermittent Fasting For Therapeutic Benefits

Physical

Beyond its application for diabetes management, IF is also proven to be as effective as approved drugs for reducing seizures and seizure-related brain damage and for healing rheumatoid arthritis.

Additionally, research is beginning to emerge showing positive effects of alternate day fasting on reducing the toxic effects of chemotherapy and decreasing morbidity rates associated with cancer.

Spiritual

Fasting is a common spiritual cleansing practice that remains an integral part of nearly all religions around the world. Its interesting to think that all of these religions are independent and unique yet they all share the use of fasting to heal and promote wellness

Some might argue that fasting is usually a practice of penance. Thats true, yes, but penance is a means to an end. The end is forgiveness and peace, self-love and well-being.

This observation in itself should represent the power of fasting!

Psychological

Fasting helps improve willpower through regularly exercising the self-control muscle. When you fast, you are consciously choosing not to eat and therefore taking control of your mind and training it just like you would train your muscles during an intense gym session.

As a result of this training, you learn how to control your own eating and you develop the power to control other aspects of your life as well.

Willpower influences your sense of accomplishment and self-esteem through being able to exhibit self-control.

Intermittent Fasting And Keto Combined

Fasting helps you get into ketosis, and being in ketosis also helps you fast.

A lot of keto-ers fast regularly because it helps them break through weight plateaus and its an effortless way to control calories. And a ketogenic diet helps with longer periods of fasting. The benefits and easier transition are mutual.

Easier transition

  • Fasting helps you avoid the keto flu and a fat-adapted or ketogenic state also prevents the fasting flu.
  • In a ketogenic, fat-adapted state, your body is already introduced to tapping into your fat stores for energy instead of relying on carbs for glucose.
  • The ketogenic diet macro portions also helps you transition to fasting easier.

Muscle protection

A high fat diet like the ketogenic diet also makes sure your body has a source of fat and uses it during your fast, instead of breaking down muscle protein for energy. For this reason, keto-ers who fast for the day drink black coffee with either heavy, full-fat cream, butter, ghee or MCT oil or powder.

Intermittent Fasting: A Formula For Health

HOW I CALCULATE MY CALORIES! (For beginner intermittent, alternate day fasting)

Dave Benton* has been in bed for three days. He is not sick. He does not have the flu. His bedridden state is self-inflicted.

He is fasting.

Fasting, or intentionally abstaining from food and drink, is often practiced as part of religious rituals, and Benton is performing his own yearly ritual the week before his birthday.

Benton spoke to me about his fasts as we sat on the back porch of his Bellingham home. The day was sunny and warm, a rarity for winter in northwest Washington. Benton turned 70 this year and has been practicing his yearly fast for more than five decades, having completed the first one when he was just 19. His fasts typically range from six to 10 days and always take place around his January birthday.

Benton is energetic and slight of frame, though does not appear undernourished. He suffers only from chronic back pain linked to years of construction work. Could his lack of chronic diseases, increasingly common in the United States, be a result of his ritual? Scientists are beginning to answer this question with growing confidence.

Their answer? A preliminary yes.

This evidence was scarce in 1969 when Dave Benton fasted for the first time. He explains, however, that he started fasting to avoid health problems that afflicted his family. Both of my parents always struggled with weight, he says, a hint of seriousness creeping into his laid-back manner of speaking.

*Not his real name.

How Much Weight Can You Lose On 1: 8 Diet

To lose weight on the 16:8 diet, its important to match the fasting with healthy eating and exercise. If done so correctly, theres a typical weight loss of around seven to 11 pounds over a ten week period. This is according to a review of 40 different studies published in Molecular and Cellular Endocrincology who found that on average, someone weighing just over 90kg would lose 5% of their total body weight in the ten week period.

A 2018 study published in the Journal of Nutrition and Healthy Eating revealed that the 16:8 diet plan can help people lose weight, without having to count calories as the 8-hour fast produces the same kind of calorific restriction and weight loss.

However, whether theres a distinct weight loss advantage achieved on the 16:8 diet compared to other diets remains to be seen. Some studies have demonstrated that theres almost no difference between people who do intermittent fasting compared those who count calories and cut back on unhealthy food.

There Are Several Methods Of Intermittent Fasting Such As:

  • Eating all meals within a 12 hour window , then fasting for 12 hours
  • Eating all meals within a 10 hour window , then fasting for 14 hours
  • Eating all meals within an 8 hour window , then fasting for 16 hours
  • OMAD
  • 5:2 this method involves eating normally five days of the week while fasting for the remaining two. You can still eat for these two days but dont exceed 600 calories.
  • Every other day fasting
  • ADF
  • The Warrior Diet
  • Eat Stop Eat
  • The Fast-5 Diet.

    Choose Which Protocol You Want To Follow

    Intermittent fasting has really taken off in recent years, and there are several popular routines to choose from.

    The ones youll hear the most about in fitness circles are Leangains, Eat Stop Eat, The Warrior Diet, and alternate-day fasting.

    There are many others, of course, but all that Ive seen are just derivatives of the above, and thus arent worth mentioning.

    Lets take a closer look at each of those above, and see what will best fit your needs.

    7 Best Intermittent Fasting Calculators of 2021

    Intermittent fasting has recently become a health trend. Devotees claim it can cause weight loss, improve metabolic health, and maybe even extend life span.

    Every method can be effective, but figuring out which one works best depends on the individual.

    Several methods of this eating pattern exist. But before embarking on an intermittent fast or deciding how often to fast, you should speak with a healthcare professional.

    Here are 6 popular ways to do intermittent fasting.

    Can Help With Fat Loss

    If fat loss is one of your health goals, time-restricted fasting can be a simple way to help stay within your daily recommended calorie amount.

    ‘In terms of fat loss, intermittent fasting works the same way as any other diet it implements a calorie deficit,’ says Maximuscle trainer, Dan Lambert. ‘Intermittent fasting simply makes “eating less” easier as you have less time to do it.’

    However, and this is important to note, it’s not necessarily the fasting for weight loss that’s helping you see results.

    ‘It’s unclear whether you would lose more fat using a fasting protocol, compared with more conventional eating patterns, where you’re eating the same amount of calories,’ says Lambert. ‘Intermittent fasting may simply allow you to sustain a calorie deficit with relative ease for a longer period of time.’

    The Leangains Macro Calculator Faq

    What should my macro percentage be?

    Your macro percentage will change as you progress with a diet and bulk phase. This is because our energy needs change over time, but protein needs do not. So, if you target specific macro ratios when cutting, youll end up under-eating protein, which can cost you muscle mass. This calculator and guide will help you avoid that.

    Do you eat the same macros on rest days?

    You can eat the same macros on your rest days, but people who follow Leangains have a lower calorie and carb intake on their rest days, with slightly higher fat intake. Select the calorie and macro cycling option in the calculator to have this calculated for you.

    How many calories do I need for a lean bulk?

    A lean bulk aims to maximize levels of leanness, while still adding muscle mass. It takes roughly ~2500 kcal to build 1 lb of muscle. So you need an approximate 100 kcal surplus to gain 1 lb of muscle per month. However, your metabolism will adapt, so this number may be higher. I like to use a 150 kcal figure.How much muscle you can gain each month depends on multiple factors, largely your genetics and how much training experience you have. Here is a rough breakdown of the rate of muscle growth the average person can expect if they do everything right: Beginner: 11.5% of body weight per month. 0.751.25% of body weight per month. Intermediate: 0.50.75% of body weight per month. Advanced: Less than 0.5% of body weight per month.

    Cons Of 1: 6 Intermittent Fasting

    For those who are used to eating all day long, limiting your meals and snacks to a six-hour window may seem impossible. It can also be tough if you have to consume a ton of daily calories, as you might find it hard to eat as many as you need without feeling stuffed. If you’re going from 16:8 to 18:6, it’ll take a week or so to get used to cutting your eating window by two hours. Also, if you don’t make a point to eat enough calories or eat enough protein and healthy fats, 18:6 may cause you to feel hungry or tired.

    Any form of intermittent fasting, especially 18:6 since it’s stricter, could potentially be a trigger for unhealthy behaviors for those with a history of eating disorders. Lisa Eberly Mastela, MPH, RD, told POPSUGAR that any form of IF should be done under the supervision of a registered dietitian, and any diet that encourages a restrictive eating schedule really should be approached with caution from the start. You might be fine doing a less rigid form of intermittent fasting, such as 16:8, but if you have any doubts, it’s best to talk to a doctor or dietitian, and, if you have a history of disordered eating, a therapist. Intermittent fasting shouldn’t negatively affect your life.

    Can We Eat Rice During Intermittent Fasting

    How I use intermittent fasting to lose weight & burn fat!

    Yes, of course.

    Remember, for weight loss, its not about giving up carbs or fats to lose weight, but rather, ensuring youre in a calorie deficit based on your body and energy requirements.

    No need to give up rice, bread, pasta, pizza, or ice cream.

    So long as you track your macros and calories, you can make it fit.

    Intermittent Fasting Can Help Weight Loss

    IF makes intuitive sense. The food we eat is broken down by enzymes in our gut and eventually ends up as molecules in our bloodstream. Carbohydrates, particularly sugars and refined grains , are quickly broken down into sugar, which our cells use for energy. If our cells dont use it all, we store it in our fat cells as, well, fat. But sugar can only enter our cells with insulin, a hormone made in the pancreas. Insulin brings sugar into the fat cells and keeps it there.

    Between meals, as long as we dont snack, our insulin levels will go down and our fat cells can then release their stored sugar, to be used as energy. We lose weight if we let our insulin levels go down. The entire idea of IF is to allow the insulin levels to go down far enough and for long enough that we burn off our fat.
