Intermittent fasting is a great tool, and it's just one of the many things you'll get in FF30X!

Yet, the goal of everything we do here at the Fit Father Project is to simplify eating and exercise for you so you can get in great shape and stay strong and healthy for yourself and your family — without any unnecessary complication.

What Is Intermittent Fasting?

The basic idea is to cycle between periods of eating and not eating. There are a few variations you could try to find out what works best for you:

1 Meal Per Day: As you can imagine, only one meal per day gives you plenty of time to fast. The meal you eat should contain a good number of calories and nutrients so you are not taking your daily intake dangerously below what you need.

16:8 Intermittent Fast: The 16:8 fast is quite popular, as it is a simple extension of a natural daily fast. Every night, when you go to bed, and usually a few hours before, you stop eating for multiple hours (depending on how long you sleep).

If you go to bed at around 10 pm, chances are you stop eating by 8 pm. If you then sleep for 8 hours and eat when you rise, you have already fasted for 10 hours. The 16:8 method simply has you eating slightly earlier on one side and later on the other side.

For example, you would stop eating at 6 pm, sleep from 10 pm until 6 am, then eat again at 10 am. Your 8-hour eating window becomes 10 am to 6 pm each day.

5:2 Intermittent Fast: Unlike the 16:8 method above, the 5:2 method is related to the days rather than the hours that you fast. This means 5 days of normal eating vs. 2 days of very low-calorie eating (approximately 500 calories).

24-Hour Fast: This simple method has you fast for a full 24 hours each week. This is best done as a meal-to-meal fast, for example, breakfast to breakfast, lunch to lunch, or dinner to dinner.

Doing it meal to meal means you will not go over the 24 hours. Some people imagine a 24-hour fast to mean not eating for a full day, but if you eat dinner at 7 pm on Monday, fast all of Tuesday, and then eat breakfast at 7 am on Wednesday, you would actually be at a 36-hour fast.

You may see other variations, but these are the methods we see used most often. The best method for you will be one that you can do consistently and that fits with your schedule without causing disruption or discomfort.

The 4 Key Benefits Of Intermittent Fasting

As you have seen from above, intermittent fasting has different variations. Some people may only do it a couple of times a week, while others do it every day or every other day.

The benefits of intermittent fasting for men may slightly outweigh the benefits for women, but that should only be viewed as a positive result for men. The research shows that intermittent fasting benefits both men and women.

Here are the 4 key benefits of intermittent fasting:

1. Intermittent Fasting Aids in Weight Loss

The best and most obvious benefit of intermittent fasting for men is that it aids in weight loss.

During the hours you are eating, it's important that you don't pack in as much food as possible.

You want to eat the normal amount of meals you would for the time period. Intermittent fasting will help you eat fewer meals and snacks in a 24-hour period. Intermittent fasting also helps to improve the function of the weight loss hormone.

As long as we don’t snack, our insulin levels will go down, and our fat cells can release their stored sugar for energy use.

Studies have shown that alternate-day fasting decreases blood sugar levels, which can be beneficial for both the management of diabetes and weight loss promotion.

2. Intermittent Fasting is Good for the Brain

There are a few ways in which intermittent fasting is good for the brain. Intermittent fasting may increase the rate at which new nerve cells grow.

This is beneficial to the brain. Cellular repair processes also improve when intermittent fasting.

This removes waste from cells and may help to prevent Alzheimer's disease. Intermittent fasting also improves brain hormone levels called brain-derived neurotrophic factor (BDNF).

Important Note: When levels of BDNF are low, you are more likely to experience depression.

3. 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.

4. Intermittent Fasting Helps to Reduce Inflammation

Inflammation is the body's response to outside threats such as toxic chemicals and infections. This is the body's way of protecting cells and tissues.

Too much inflammation in the body is a different story, though. Too much inflammation is linked to lupus, rheumatoid arthritis, gut problems such as ulcerative colitis, and gouty arthritis.

Symptoms of inflammation include joint pain and stiffness, redness, fatigue, headaches, and muscle stiffness.

Intermittent fasting can reduce inflammation throughout the body.

Intermittent fasting benefits your body and health in many ways. An intermittent fasting cycle is flexible, so you can adjust it to suit your lifestyle.

The 3 Simple Rules Of Intermittent Fasting

intermittent fasting for men

There are a few rules you need to follow if you want intermittent fasting for men to work out for you.

1. Get Plenty Of Sleep

Sleep is good for you anyway, but getting plenty of sleep while intermittent fasting helps you stick with it. You will be less prone to energy ‘crashes', meaning you will not reach for sugary snacks to ‘perk you up'.

Also, if you go to bed at midnight, you may often “fight” late-night cravings, but if you go to bed at 10 pm, 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 16 hours and do all their eating in an 8-hour window. This means you effectively either skip breakfast or dinner. Most people choose to skip breakfast and eat lunch and dinner as normal.

2. Drink Water (Or Coffee) To Hold You Over

You should already be drinking plenty of water every day. This is especially true during intermittent fasting, but if you need something “heartier,” coffee is another option.

While some versions of intermittent fasting allow one shot of cream in your coffee, the choice is entirely up to you. It is important not to go crazy with it — don't add 2 or 3 shots of cream and/or tablespoons of sugar.

Finally, eat everything you're going to eat for the day within 8 hours. This can be tricky if you're not used to it. If you get up at 6 am and eat by 7 am, you can eat a big breakfast and a moderately large lunch, as long as you stop eating by 3 pm.

Alternatively, you can skip breakfast and eat lunch at noon and dinner sometime before 8 pm.

3. Choose An Eating Window You Will Stick To

Again, the most common fasting schedule is fasting for 16 hours (mostly while sleeping) and doing all your eating in an 8-hour window (10 am to 6 pm, for instance). But, if your eating window overlaps the time you usually work out, you may want to change it up to work with your schedule.

Intermittent fasting is a great strategy for increasing your chances of weight loss, but it won't help if you don't stick to the plan. Here's a reminder of the several methods of intermittent fasting from before:

    • 1-meal per day
    • 16:8 Intermittent Fast
    • 5:2 Intermittent Fast
    • 24-Hour Fast

To optimize your rate of weight loss, you will need to develop a schedule that works for you. Find the hours of the day that are easiest for you to eat without disrupting your normal work or exercise schedule.

What To Avoid When Intermittent Fasting

There are a few traps people fall into when doing intermittent fasting.

First, some people don't track their “eating window” and eat outside of the 8 hours. The result is they're not fasting long enough and don't get the results they want.

Another mistake people make is that they don't make their 8-hour window consistent daily.

Remember, consistency is key!

Choose an 8-hour timeframe when you'll eat and stick to it. If you want to eat breakfast, start your eating window and do it daily.

Your body gets used to eating at the same time every day, so don't confuse it, or it'll be hard to stick to your fast.

Intermittent fasting can be difficult at first because most people aren't used to skipping meals. A new habit needs to be formed. However, those who switch often find fasting enough to lose weight and don't have to remember complicated dieting rules or deprive themselves of foods they enjoy.

Most importantly, don't go overboard during the eating period!

You may find yourself feeling hungry after an extended period of not eating. Be conscious of why you're fasting in the first place, and stick to a healthy diet.

Increase the Effectiveness of Intermittent Fasting

To say intermittent fasting is a popular weight-loss trend would likely be the understatement of the year.

Weight loss enthusiasts are flocking to this healthy eating plan thanks to its excellent weight loss results over short periods of time.

If you're considering using time-restricted eating to help you lose weight fast, the following are a few hacks you should know to increase the effectiveness of your intermittent fasting diet.

Follow a Calorie-Restricted Diet

This one is simple and obvious. During your eating hours, make sure you're eating healthy foods. Stick to good carbohydrates, lean protein, and lots of vegetables. Eat foods that increase satiety, like eggs, fish, apples, nuts, and almost all vegetables.

Increase Restricted Hours

Many dieters attempting to lose weight quickly via intermittent fasting restrict their food intake to only 12-14 hours.

If you restrict your food intake to 16 hours, you can increase the rate at which you lose weight.

Stop eating by 8 pm in the evening, and most of your non-eating hours will occur while you're asleep.

Selective Carbohydrate Eating

Just because you're using time-restricted eating to lose weight doesn't mean you should consume high-carbohydrate or sugar-rich foods when you're not in fasting mode.

Eat low-glycemic carbohydrates instead of high-carbohydrate foods, and you'll speed up your weight loss rate.

Carbohydrates are necessary for healthy eating, but you must be smart when choosing the appropriate ones.

Focus on eating carbohydrates that convert to sugar at a slower rate, and you'll be amazed at how quickly you can shed pounds.

Protein Is Key

When your intermittent fasting period is over, focus on eating foods high in protein.

Instead of instantly consuming carbohydrates once your 16 hours of fasting have passed, eat protein-rich foods like chicken, tuna, and turkey instead.

This helps keep your body in fat-burning mode longer and gives your body the necessary proteins, too.
