Choose How Youll Fast

Fasting is distinct from the likes of a juice cleanse or a two-day restrictive diet. There are two categoriestraditional and intermittenteach of which appeals to different individuals depending on their goals and lifestyles.

While both can be beneficial to your brain health, intermittent fasting is better for weight loss and maintenance. Pick the one that works best for what you want to accomplish.

What Are The Methods Of Intermittent Fasting

These are the four intermittent fasting approaches people most commonly use:

  • The 16/8 Method: This approach may be among the easiest to adopt. People fast for 16 hours and have an eight-hour window for eating. For example, you could eat every day from 12 p.m. to 8 p.m. After 8 p.m.until 12 p.m. the next dayyou can only drink no-calorie beverages like water, lemon water, tea, and coffee.
  • The 5:2 Method: Also known as alternate-day fasting, this method suggests that you eat normally five days a week and then fast for 24 hours, allowing yourself just 500 to 600 calories. You pick two days a week to fastsay Monday and Thursday, for example. Learn more about alternate-day fasting schedules.
  • Eat-Stop-Eat: This is the same as the 5:2 method, except that you dont get any calories for those two non-consecutive days per week.
  • The Warrior Method: People who use this method condense their eating into just four hours per day. The other 20 is spent fasting. This method is more complicated. Nutritionists share what you should know about the Warrior Method before trying it.

Types Of Intermittent Fasting

Intermittent fasting can be done in many ways. It is a flexible method that allows adaptation to the needs of each one. It usually ranges from a few hours to 1 or 2 days, although longer periods require professional monitoring.

Most programs include 24-hour fasting periods that are practiced 1 or 2 days a week. These are not consecutive and in them only liquid or a meal of 500 calories maximum is ingested.

Nevertheless, the most common way to start the fast is usually time-restricted feeding. This involves, for example, doing all the intakes within an 8-hour window and resting for the remaining 16 hours.

These periods can be 4, 6, 8 or 10 hours according to the convenience of each person. In addition, the time of day you eat can also be adapted.

Does Intermittent Fasting Have Different Effects On Men And Women

Remarkable weight loss after hysterectomy with ...

The quick answer is: yes, Intermittent Fasting can affect men and women differently.

Anecdotally, we have many women in our online coaching program that swear by Intermittent Fasting, while others have had adverse effects.

Lets dig into the science and studies.

A recent PubMed summary concluded thatfasting can be prescribed as a safe medical intervention as well as a lifestyle regimen which can improve womens health in many folds .

Now, in that extract, many of the studies cited are focused on specifically calorie restriction , and they also say that future studies should address this gap by designing medically supervised fasting techniques to extract better evidence.

Digging into the PubMed Archives brought me to the following conclusions :

One small study resulted in the following: Glucose response to a meal was slightly impaired in women after 3 weeks of treatment, but insulin response was unchanged. Men had no change in glucose response and a significant reduction in insulin response.

Another small study studied the effects on their menstrual cycles after a 72 hour fast which is significantly longer than any fast recommended in this article: in spite of profound metabolic changes, a 72-hour fast during the follicular phase does not affect the menstrual cycle of normal cycling women..

Before You Get Started

  • Talk to your doctor before you start. Especially if you have any medical condition or if youre on any medication. Stop if you feel sick.
  • Keep it simple. Fasting is defined as consuming only plain water , or black coffee, or unsweetened tea.
  • Keep it easy. Eat your usual meals during your eating window. In my personal experience, intermittent fasting works best when combined with a low carb-high fat diet of real, whole foods. But launching the perfect combination to get the best results is not your goal right nowits to finish a fast.
  • Time is mentioned for simplicity. You dont have to follow them. You may adjust the times according to your schedule.
  • Which days of the week? In my experience, fasting on weekdays are more convenient because theyre more structured and have less variables. But that may not be true for you. What youre looking for are those days where youre more likely to say, Whered the time go? I forgot to eat!
  • Slip ups are okay. First, forgive yourself. You may pick up where you left off or start from Day 1. Do whats easiest to get you back on track. Next
  • If you’re looking for a simple, doable way to practice fasting, I get it. It shouldn’t have to be hard. Get my FREE email course below that shows you the easier way.

    Eat for your goals. This is the only recommendation possible. You should avoid snacks in between your meals but this is not mandatory and if you feel you need a snack, go for it!

    Dont overthink it keep things simple, and youll see big changes in your body and your life!

    Science Of Intermittent Fasting For Weight Loss

    To understand the science of intermittent fasting, we need to look into the basics of nutrition.

    And it is quite straight-forward: the food we eat gets broken down to molecules and ends up in our blood, which feeds the cells in our bodies.

    Part of those molecules are net carbohydrates and our body turns them into sugar so our cells could use it for energy.

    To be able to use sugar for the energy we need insulin, which is produced in our pancreas and spikes each time we throw in some food with carbohydrates.

    Any excess sugars that we dont utilize get stored in the form of fat with the idea that we will use that fat for energy later, once we have no sugar left.

    The best way to NOT end up having huge fat reserves is to spend the same amount of energy you get from food.

    However, life is not perfect and many of us have lifestyles that limit our chances to move throughout the day. In fact, office workers tend to spend 75% of their waking hours sitting.

    So, what can we do to lose or not gain weight?

    One way to do it is to focus on increasing your energy expenditure through increased physical activity or in laymans terms exercising and doing sports. But you knew this one already, didnt you?

    Another way though is to focus on consuming less food than you need for the energy that day and as a result, creating a caloric deficit.

    And thats where intermittent fasting comes in.

    What Can I Eat While Intermittent Fasting

    How To Start Intermittent Fasting | Weight Loss Tips

    During the times when youre not eating, water and zero-calorie beverages such as black coffee and tea are permitted.

    And during your eating periods, eating normally does not mean going crazy. Youre not likely to lose weight or get healthier if you pack your feeding times with high-calorie junk food, super-sized fried items and treats.

    But what Williams likes about intermittent fasting is that it allows for a range of different foods to be eaten and enjoyed. We want people to be mindful and take pleasure in eating good, nutritious food, she says. She adds that eating with others and sharing the mealtime experience adds satisfaction and supports good health.

    Williams, like most nutrition experts, regards the Mediterranean diet as a good blueprint of what to eat, whether youre trying intermittent fasting or not. You can hardly go wrong when you pick complex, unrefined carbohydrates such as whole grains, leafy greens, healthy fats and lean protein.

    The 4 Main Types Of Intermittent Fasting

    The main types of intermittent fasting are:

    • 16-hour fasting – this consists of not eating for 14 to 16 hours, including the sleep period, and then eating during the remaining 8 hours of the day. For example, having dinner at 6 pm and then only start eating again at 10 am the next day
    • 24-hour fasting – this consists of a whole day and night fast, two to three times a week
    • 36-hour fasting – this consists of not eating for one and a half days. For example, eating at 6 pm on one day and then not eating the whole of the next day and eat at 6 am on the following day. This type of fasting should only be done under doctor supervision and by those who are already used to fasting
    • 5:2 diet – this consists of eating normally for 5 days and restricting food intake for 2 days by reducing calorie intake to around 500.

    During the “no eating” period, you are allowed to have water and tea or coffee without sugar or sweeteners. It is common to feel very hungry in the first few days but then the body gets used to it. If you feel extremely hungry, just eat something light as it is not advisable to feel unwell if you are trying to adopt this habit.

    Isnt It Important To Have Breakfast Every Morning

    Not necessarily. This appears to be an old misconception, based on speculation and statistics, and it does not hold up when its tested.57 Skipping your morning meal gives your body more time to burn fat for energy. Since hunger is lowest in the morning, it may be easiest to skip it and break your fast later in the day.58

    How Gender Impacts Your Fasting Routine

    From a biological standpoint, gender can impact the success of intermittent fasting. Male and female body composition and metabolic systems are different from each other. Physical activity, hormone levels, caloric intake, and fasting impact each of us differently.

    Due to these reasons, males tend to benefit from fasting more than females. Females also should not focus on long-term fasting or drastic reduction in caloric intake.

    Over thousands of years, the genetic makeup of females benefits most from the constant intake of high-quality calories, which eliminates such fasting regimes as 20:4 fasting from a female routine. The optimal amount of fasting would be 14 hours per day.

    For males, skipping breakfast or skipping a day of eating might be just what the doctor recommended.

    In both cases, the most important thing is to avoid hangriness, a state when you become very upset while hungry. The key here is to balance out your meals and eat highly nutritious meals throughout the eating window.

    Generally, try to eat high-protein and high-fiber dishes to stay satiated for longer.

    What Should You Eat

    The Ultimate Intermittent Fasting Guide For Beginners ...

    Most diets focus on eating healthy foods, and intermittent fasting is no exception.

    Do keep in mind that your body needs nutrients to function optimally. When you eat junk and processed foods that are not nutritious, you wont be able to lose weight.

    During your eating period, you should eat and drink:

    Drawbacks Of 16/8 Intermittent Fasting

    16/8 intermittent fasting may be associated with many health benefits, but it does come with some drawbacks and may not be right for everyone.

    Restricting your intake to just eight hours per day can cause some people to eat more than usual during eating periods in an attempt to make up for hours spent fasting.

    This may lead to weight gain, digestive problems and the development of unhealthy eating habits.

    16/8 intermittent fasting may also cause short-term negative side effects when youre first getting started, such as hunger, weakness and fatigue though these often subside once you get into a routine.

    Additionally, some research suggests that intermittent fasting may affect men and women differently, with animal studies reporting that it could interfere with fertility and reproduction in females .

    However, more human studies are needed to evaluate the effects that intermittent fasting may have on reproductive health.

    In any case, be sure to start gradually and consider stopping or consulting your doctor if you have any concerns or experience negative symptoms.


    Restricting daily food intake may cause weakness, hunger, increased food consumption and weight gain. Animal studies show that intermittent fasting may impact men and women differently and may even interfere with fertility.

    What Is The Keto Diet

    The ketogenic diet is a high-fat, very low-carb way of eating.

    Carbs are typically reduced to 20 to 50 grams per day, which forces your body to rely on fats instead of glucose for its main energy source .

    In the metabolic process known as ketosis, your body breaks down fats to form substances called ketones that serve as an alternate fuel source .

    This diet is an effective way to shed pounds, but it has several other benefits as well.

    The keto diet has been used for nearly a century to treat epilepsy and also demonstrates promise for other neurological disorders (

    8 ).

    Whats more, it may reduce blood sugar, improve insulin resistance and lower heart disease risk factors like triglyceride levels .


    The ketogenic diet is a very low-carb, high-fat diet linked to potential health benefits, such as weight loss and improved blood sugar control.

    If you commit to the ketogenic diet while doing intermittent fasting as well, it could offer the following benefits.

    How To Do A Fat Fast With A 1: 8 Intermittent Fast

    To work this extreme version of intermittent fasting into your diet, you need to be smart with your food choices.

    Common healthy fats, like nuts, seeds, and cheese contain some carbohydrate and protein grams, so you cannot munch on these foods with carefree abandon during your eight-hour eating window.

    Instead, you need to stick with your more healthy saturated fats, like butter MCT oil, and coconut oil.

    These foods are almost purely fat and can be consumed in a hot drink, such as coffee.

    Dave Asprey popularized a high-fat coffee drink that he calls BulletProof Coffee, which is a coffee drink that includes butter and MCT oil.

    Today we see many versions of this original recipe, most of them going by the name Keto Coffee.

    My husband has his own version of this buttery coffee. In his version, which he calls Fat-Fortified Coffee, he adds heavy whipping cream for flavor. We share the recipe in our 2 Fit Docs 21-Day Challenge.

    As Keith was losing weight, he would occasionally do a fat fast by consuming two Fat-Fortified Coffees within an eight-hour window. That was it, nothing else to eat.

    While it sounds like hunger would be a big factor, he stated that the fats helped to keep hunger at bay.

    Types Of Intermittent Fasting Schedules That Produce Results

    How to start intermittent fasting

    Although intermittent fasting has quickly become more and more popular for weight loss, information about it is only just starting to come out. The reason it has become so popular is that it is relatively easy to stick to, and doesnt restrict you from eating your favorite foods.
