When Should I Exercise
When Varady and her colleagues conducted a study that combined alternate day fasting and exercise, they allowed the participants to pick whether they wanted to exercise on a feasting or fasting day, and found there was no strong preference one way or the other. But the researchers were surprised the dieters actually reported feeling more energetic on fasting days.
Why Does My Blood Sugar Go Up During Fasting
While this does not happen with everyone, it can occur due to hormonal changes that occur during intermittent fasting. Your body is producing sugar in order to provide energy for your system. This is a variation of the dawn phenomenon and in general is not a concern as long as blood sugars are not elevated the rest of the day.45

Yes You Can Have Water
To get the full benefits of fasting, its important not to consume any food during your fasting window but you can drink water, black coffee and tea, says Pleimling. Be aware that caffeinated drinks can dehydrate you when your body is already depleted of energy though, says Carrie Lam, a family medicine doctor in Loma Linda, California. She also says alcohol is off the table during the fasting window.
The Science Behind Intermittent Fasting
There are thousands of information out there about the true science behind intermittent fasting. I read numerous researches and can tell you that most of them agree that periodic fasting is good for us.
Science has proven that after 12 hours of fasting, the growth hormone works at its best because the insulin level is very low. Also, after 24h of fasting certain cells in our guts start to regenerate. I even managed to find articles where people give their testimonies about treating serious diseases with fasting, such as cancer.
Cole Robinson said the great thing in one video on his YouTube channel: Of course it heals your body, no sickness can live if you don’t feed it!. That makes sense because if you don’t feed something, it will eventually die!

Intermittent Fasting May Benefit The Heart
According to the Intermountain Medical Center, intermittent fasting plays a role in keeping the heart healthy.
This is great news considering heart disease is a leading cause of death around the world.
Intermittent fasting helps to lower blood pressure, which is good for the heart.
LDL and total cholesterol levels will also be improved.
Blood sugar levels will benefit from intermittent fasting as well.
Keeping the heart healthy will help to prevent heart disease.
If you have a history of heart disease in your family, intermittent fasting is something you may want to consider.
The Ketogenic Diet Keeps You Satisfied
Another great perk of the keto diet is its high level of satiety.
Not only does ketosis itself tend to stifle hunger, but the high level of healthy fat in the keto diet also makes it much easier to stay satisfied in a fasted state and eliminates those intense feelings of hunger and cravings throughout the day.
This is perfect for someone doing intermittent fasting.

It May Be Difficult For Some People To Stick To
One of the most obvious limitations of the Warrior Diet is that it restricts the time during which you may eat substantial meals to a four-hour period.
This can be difficult to stick to, especially when participating in normal social activities like going out to breakfast or lunch.
While some people may feel great when consuming very small amounts of calories over a 20-hour period, others may find that this way of eating is not ideal for their lifestyle.
Styles Of Intermittent Fasting

Getting Started With Intermittent Fasting: Next Steps
Intermittent fasting can potentially have some very positive benefits for somebody trying to lose weight or gain lean body mass.
Men and women will tend to have different results, just like each individual person will have different results. The ONLY way to find out is through a conversation with your doctor and self-experimentation.
There are multiple ways to do an Intermittent Fasting Plan:
- Fast and feast regularly: Fast for a certain number of hours, then consume all calories within a certain number of hours.
- Eat normally, then fast 1-2x a week: Consume your normal meals every day, then pick one or two days a week where you fast for 24 hours. Eat your last meal Sunday night, and then dont eat again until dinner the following day.
- Fast occasionally: probably the easiest method for the person who wants to do the least amount of work. Simply skip a meal whenever its convenient. On the road? Skip breakfast. Busy day at work? Skip lunch. Eat poorly all day Saturday? Make your first meal of the day dinner on Sunday.
After that, get started! Take photos, step on the scale, and track your progress for the next month.
See how your body responds.
See how your physique changes. See how your workouts change.
And then decide if its something you want to keep doing!
4 years later, I have no plans on going back to eating breakfast. Sorry General Mills and Dr. Kellogg!

Simple Rules Of Fasting
There are a few rules you need to follow if you want intermittent fasting for men to work out for you.
First, get plenty of sleep.
Sleep is good for you anyway, but getting more sleep while doing intermittent fasting increases the likelihood you’ll stick with it because you are awake fewer hours during the day.
That translates into less willpower needed to stick to the fast.
For example, if you go to bed at midnight and get up at 6 a.m to go to work, you have to fight late-night cravings.
If you go to bed at 10 p.m., it shaves 2 hours off your day, and you’re less likely to have a midnight snack if you’re already in bed and sleeping.
Most people choose to fast for 14 to 16 hours.
This means you effectively either skip breakfast or dinner. Most people choose to skip breakfast and eat lunch and dinner as normal.
Drink coffee to hold you over.
While some versions of intermittent fasting allow one shot of cream in your coffee, the choice is entirely up to you.
The important thing is to not go crazy with it. For example, don’t add 2 or 3 shots of cream and a tablespoon of sugar.
Finally, eat everything you’re going to eat for the day inside of 8 hours.
This can be tricky if you’re not used to it.
If you get up at 6 a.m. and eat by 7 a.m., you can eat a big breakfast and a moderately-large lunch, as long as you stop eating by 3 p.m.
Alternatively, you can skip breakfast and eat lunch at noon, and dinner sometime before 8 p.m.

How To Eat On Fasting Days
There is no rule for what or when to eat on fasting days.
Some people function best by beginning the day with a small breakfast, while others find it best to start eating as late as possible.
Generally, there are two meal patterns that people follow:
Since calorie intake is limited 500 calories for women and 600 calories for men it makes sense to use your calorie budget wisely.
Try to focus on nutritious, high-fiber, high-protein foods that will make you feel full without consuming too many calories.
Soups are a great option on fast days. Studies have shown that they may make you feel more full than the same ingredients in original form, or foods with the same calorie content (
There is no specific, correct way to eat on fasting days. You have to experiment and figure out what works best for you.
What Are The Possible Side Effects
There can be a number of possible side effects of intermittent fasting.40 Heres what to do if you encounter them:
- Hunger is the most common side effect of intermittent fasting. This may be less of an issue if youre already on a keto or low-carb, higher-fat diet.41Learn more
- Constipation is common. Less going in means less going out. However, keep in mind this is a normal response to eating less. It is not a concern and shouldnt require treatment unless you experience significant bloating or abdominal discomfort. Standard laxatives or magnesium supplements can be used, if needed.
- Headaches are common and tend to disappear after the first few times on fasts.42 Taking some extra salt often helps mitigate such headaches.43
- Mineral water may help if your stomach tends to gurgle.
- Other possible side effects include dizziness, heartburn and muscle cramps. Learn more
A more serious side effect is the refeeding syndrome. Fortunately, this is rare and generally only happens with extended fasts when one is undernourished.44
Since most of these side effects are manageable, they do not mean you have to stop your fast. However, if you truly feel unwell, are excessively dizzy, profoundly weak or have other severe symptoms, then you should break your fast.
Just remember to go slowly when you break it and prioritize fluids and salt . And of course, if the symptoms persist, see your doctor immediately.

May Lead To More Fat Loss
Combining the diet and the fast may help you burn more fat than the diet alone.
Because intermittent fasting boosts metabolism by promoting thermogenesis, or heat production, your body may start utilizing stubborn fat stores .
Several studies reveal that intermittent fasting can powerfully and safely drop excess body fat.
In an eight-week study in 34 resistance-trained men, those who practiced the 16/8 method of intermittent fasting lost nearly 14% more body fat than those following a normal eating pattern .
Similarly, a review of 28 studies noted that people who used intermittent fasting lost an average of 7.3 pounds more fat mass than those following very low-calorie diets .
Plus, intermittent fasting may preserve muscle mass during weight loss and improve energy levels, which may be helpful for keto dieters looking to improve athletic performance and drop body fat .
Additionally, studies underscore that intermittent fasting can reduce hunger and promote feelings of fullness, which may aid weight loss .
Summary
Combining intermittent fasting with a keto diet may help you reach ketosis faster and drop more body fat than a keto diet alone.
Combining the ketogenic diet with intermittent fasting is likely safe for most people.
However, pregnant or breastfeeding women and those with a history of disordered eating should avoid intermittent fasting.
Though some people may find merging the practices helpful, its important to note that it may not work for everyone.

Hormonal Changes And Menstrual Cycles
Some animal research suggests that intermittent fasting may lead to hormonal changes and undereating. In people with ovaries, these changes may negatively affect menstrual cycles and fertility .
However, most studies are old and have been conducted in animals. Human studies are needed to fully understand how intermittent fasting may affect reproductive health.
Furthermore, postmenopausal individuals may experience different effects from intermittent fasting. Menopause causes changes that can decrease insulin sensitivity and lead to weight gain, and intermittent fasting may help improve these outcomes .
Summary
Restricting daily food intake to a particular time window may cause increased food intake and weight gain, as well as short-term hunger and weakness. Older animal studies indicate that intermittent fasting may interfere with fertility.
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.

So Should I Do Intermittent Fasting Daily
The answer depends on your routine and schedule. For some people who work Monday-Friday and then have the weekends off, they may prefer to only intermittent fast during the weekdays so they can enjoy their weekend. There is nothing wrong with fasting only 4-5 days out of the week. The problem many people run into during the weekend is that they stay up much later compared to the weekdays, so in order to fast like normal they would have to push their first meal back super late in the day.
For example, say that Monday-Friday you usually stop eating at 8pm and eat at noon the next day , but then on the weekend you stay up late . That means the following day you wouldnt be able to eat until 4pm, which makes it much harder for those who enjoy staying out late during the weekends to continue their normal weekday intermittent fasting routine.
So rather than stress and worry about it, you can simply not practice intermittent fasting on Saturday and/or Sunday, and then continue your normal intermittent fasting routine on Monday.
So should you intermittent fast daily?
