Intermittent Fasting Diet: 101 Nutrition Guide, Exercises and Benefits

Intermittent Fasting Diet Plan - Fitzabout

Intermittent fasting is the most popular health and fitness trends, not a starvation diet. On the other hand, it’s also not a way to eat a steady diet of junk food and get away with it.

Intermittent Fasting Diet differs from normal dieting because it adapts to the way your body functions, it charges your body with nutrients that make you feel energized while enabling lasting weight loss.

What is Intermittent Fasting (IF)?

Intermittent Fasting (IF) is a planned program of eating that allows you to eat a normal, healthy diet most of the time, and then requires you to expend very few meals to take less time.

Intermittent fasting is not among fasting practices, it is neither a religious practice, nor is it motivated by lack of time or food – it is a choice. It is best described as an eating pattern that alternates between periods of eating and periods of fasting, each period lasting a predetermined amount of time.

There are some intermittent fasting plans that divide fasting and non-fasting periods into just hours, such as an eight-hour meal followed by a twelve- or sixteen-hour fast. More commonly, intermittent fasting is divided by days of the week.

  • For example:
    • 16:8 Method: In 16:8 method, the duration of fasting is 16 hours and the duration of eating is 8 hours.
    • 5:2 Fast Diet: On the 5:2 Fast Diet, you eat a “normal” diet for five days of the week, with two days of fasting in between.
    • Eat-Stop-Eat: This involves fasting for 24 hours once or twice a week, for example, from dinner one day until dinner the next day.

Intermittent Fasting (IF) 16/8 Method

There are different ways to practice IF, however, they all have one equality; They all include a feeding period and a fasting period.

  • Duration of Fasting – This varies in length of time for different methods. During this, you either do not eat anything or consume zero calorie beverages.
  • Feeding Duration – This also varies in the length of time for each method. In the meantime, you can eat whatever you want to avoid overfeeding. It is advised that you eat ‘normally’, not compensating for the period you went without food. Some methods, such as The Warrior Diet, may require that you eat in a certain order.

Before we look at the Intermittent Fasting (IF) 16:8 method, it’s important to point out that intermittent fasting is not for everyone. Below are some people who should not do intermittent fasting:

Note: Before making any dietary, physical exercise program or changes to your normal habits, you should see a doctor or other relevant professional.

Intermittent Fasting 16/8 Lean Gain Protocol

As the name suggests, this method is divided into two periods; A 16-hour fasting period and a typical 8-hour meal period. It is important that you keep your feeding period constant. This means that you can decide not to eat from 8 a.m. to 4 p.m. today and shift it from 8 p.m. to 4 p.m. the next day. This is to create a schedule that is easy for your body and easy to follow. Remember, the hunger hormone ghrelin is released in relation to your eating patterns? Changing your patterns constantly can leave you hungry all the time and messing with the hormones.

This method is said to be more sustainable and easier to maintain because you don’t need to spend a very long time without food, and it can easily fit into most people’s daily lives. For example, the average person sleeps for 8 hours. You only need to fast for another 8 hours while awake, which makes the duration of the fast seem shorter.

For example, if your last meal was at 10 p.m., you fast until 2 p.m. the next day, some of which you’ll be sleeping, and the rest busy with work – you’ll barely keep track of time. This method is popular because you can have dinner with family or friends even before your feeding window closes.

Important note: Some research suggests that eating late at night produces more insulin spikes than during the day, affecting sleep quality and promoting overnight storage.

Intermittent Fasting 16/8 three factors to success

Factor-1: Diet and nutrition

As you probably know, nutrition plays an important role in any health and fitness journey. You know that vegetables are good for you, meat contains protein, and you probably know that processed food is generally bad. I’m not going to give you the same old bread, pasta blah blah spiel you’ve heard a hundred times. However, we’ll cover two essential electrolytes that are important for your weight loss that people often lack as well as how much fat, protein and carbs you should consume for best results.

Note: In the beginning, just focus on getting used to the window. You will get immediate results. Once you get used to the IF 16:8 diet lifestyle, move on to more advanced concepts for further results.

Fats, Carbs and Proteins

The aim of the game is to burn through glycogen stores, forcing the body to use up fat. Over time, the aim is to get the bodies used to burning fat as the primary fuel source to stay lean throughout the year. The best way to do this is to restrict carbs and increase the consumption of fat. It is worth noting that protein should be kept at a moderate level, as too much can be converted into glucose and stored by the body as glycogen.

Below are some examples of common macros. I would like to take this opportunity to note that you do not need to be keto or follow a ketogenic diet to get Intermittent Fasting (IF) results.

Note: Always be sure to consult the doctor before changing the diet.

Protein Guidelines

A common mistake when trying to lose weight is eating too much protein, excess protein can be converted to glucose (sugar) and stored as glycogen. Due to the difference in atomic structure, glucose cannot be converted back to protein. Use the given equations to calculate your protein needs based on your goal.

Weight loss

For weight loss, 0.36g – 0.7g per pound of target body weight.

  • Example: When the weight is 198lb, but the target weight is 174lb.
    • 0.36 x 174 = 62.64g
    • 0.70 x 174 = 121.8g

The ideal daily intake of protein is 62 grams – 122 grams.

Take in at least 62 grams of protein per day to maintain muscle mass, but eat no more than 122 grams per day to avoid converting protein into glucose.

Bulking

For bulking, 1.5g – 2g per pound of target body weight.

  • Example: When the weight is 165lb, but its target weight is 200lb.
    • 1.5 x 165 = 247.5g
    • 2 x 165 = 330g

The ideal daily protein intake is going to be 247g – 330g.

Certainly, supplements will be needed, as the amount of food needed to obtain this amount of protein may be unbearable to eat. When bulking, it is common to have an increase in body fat percentage, but a cutting phase will be implemented once the target weight is achieved.

Carbohydrate Guidelines

Carbohydrates can be difficult to calculate, as it varies from person to person. Below are the guidelines you can follow.

Keto

For keto, 30 grams or fewer per day.

These should mainly come from leafy greens. This method is a principle derived from the ketogenic diet.

Plateau Buster

For plateau buster, 100 grams or fewer per day.

  • These should mainly come from leafy greens and resistant starch.
  • If you’ve hit a plateau, the principle is easy.

Beginners

Beginners eliminate refined sugars, instead of focusing on macros, focus on eliminating refined sugars and incorporating resistant starches.

Resistant starch

It is resistant to digestion and acts like soluble fiber. They help reduce blood sugar levels and insulin resistance, among other things. These are a better choice than traditional carbohydrate alternatives.

  • Example:
    • Sweet potatoes and yams instead of potatoes
    • Oats instead of cereals
    • Cooked and cold rice instead of hot rice
    • Green bananas instead of other fruits
Fat guidelines

Some people still find it difficult to understand that fat intake does not automatically transfer to “being fat”.

If you want to burn fat as fuel to lose weight forever, you need to think about eating more fat than you might have thought healthy. I’m not saying you have to go keto, but a consistent intake of saturated fat (yes, you read that right) will help your body burn fat as fuel.

Avoid Trans-Fat and Hydrogenated Oils

Partially hydrogenated oils contain trans-fats. Trans fat causes a variety of health problems, including an increase in LDL (“bad”) cholesterol.

Eat saturated fat

Fully hydrogenated fats become saturated fats. Difference? They do not contain any trans-fats. If it remains solid at normal room temperature, it is safe to assume that it is saturated fat.

  • Examples of healthy fats:
    • Whole eggs
    • Cheese
    • Fatty fish
    • Extra virgin olive oil
    • Coconut oil
    • Avocado
    • Full fat curd
    • Nuts
Cooking guidelines

Saturated fat is the safest substance to cook. Unlike other fats and oils, saturated fat does not hydrogenate under heat.

Tips

Avoid cooking in vegetable and soybean oils as they contain hydrogenated oils. Although olive oil is a healthy form of fat when it is cold, it becomes partially hydrogenated when heated. Use for dressing, but not for cooking.

Remember, if it’s solid at normal room temperature, it’s probably saturated fat. Any fat that remains liquid at normal room temperature (even healthy ones) will hydrogenate under heat.

Factor-2: Exercise

There are many amazing benefits of exercise. It can help with depression and anxiety, as well as help you achieve your beauty goals. Exercise is also going to play a role in the balancing of hormones mentioned earlier. Exercise promotes the production of HGH, but will also help to quickly deplete glycogen stores.

What is the best exercise while fasting?

It is a popular belief that long-term cardio at a steady pace is the best way to burn fat. Not so in my experience. While this has its benefits, when it comes to burning fat and the Intermittent Fasting (IF) lifestyle, I have had far more success with HIIT training for both female and male clients.

HIIT (High Intensity Interval Training)

If burning fat is your mission, I recommend HIIT training. Fast-paced workouts that can be done in 30 minutes make it ideal for someone with a busy lifestyle. HIIT can be done with bodyweight exercises, barbells, kettlebells and dumbbells. I usually use exercises that use more than one muscle group. For example, a row instead of a biceps curl. Short bursts are the name of the game at almost maximum effort. Below are some guidelines you can play with.

Beginner
ExercisesTime
Squat10 seconds
Running on the spot10 seconds
Star Jumps10 seconds

EXERCISING TIPS: Do each exercise 10 seconds; Do each exercise back-to-back for 3 rounds and rest 30 seconds between rounds.

EXERCISING TIPS: Do each exercise 20 seconds; Do each exercise back-to-back for 8-10 rounds and rest 10 seconds between rounds.

Factor-3: The Importance of Recovery, Rest and Sleep

Getting proper sleep can skyrocket the results. During sleep, your body mainly enters into anabolic (building) type phase. Your body believes it or not to repair damage, replace cells, and burn fat.

Good sleep is linked to the creation of this hormone. If you are not getting quality sleep at the right time, then all the exercise and healthy eating may not give the results you were hoping for. If you’ve ever dieted before patting yourself at the gym only to see little or no results, you know how frustrating it can be! Maybe proper sleep was the missing piece you needed!

Tips to get a good night’s sleep
1. Get more sunlight

The body’s circadian system or “body clock” plays a huge role in the production of hormones. It is heavily influenced by sunlight.

Sunlight, especially morning sunlight, prompts glands and organs to wake up, queuing them to produce daytime hormones (most of which help keep you alert and awake). Your circadian clock gets disturbed if the body gets unskilled sunlight in the morning and then too much artificial light at night (such as TVs, laptops and smartphones). This can cause the glands to produce hormones that prevent you from sleeping.

Lack of good sleep is going to hinder the production of hormones like HGH and can even increase the build-up of hormones like insulin. If this happens, you will not be able to burn fat overnight!

2. Avoid screens before sleeping

If you’re the kind of person who tends to fall asleep at 11 p.m. watching TV or watching YouTube on your phone, the quickest way to improve sleep would be to stop using your devices at least an hour before bedtime. Give.

Remember how the body clock is affected by sunlight? It is also affected by artificial light. The eyes are a major light sensor, and the blue light produced by your favorite screen stimulates the body to produce daytime hormones that are primarily meant to keep you awake and active.

With these bad boys rushing your body, it’ll be harder to fall asleep, and your body won’t be producing those sweet anabolic hormones you need to repair and lose weight.

3. Sleep in the dark

While it may seem obvious after the first two tips, some of you ignore this tip when not told. You can’t control the outside lights, like street lamps and annoying security lights, but they can still affect your sleep on a molecular level, hindering repair and making us tired the next day. Darken your windows with heavy-duty curtains to stop outside light ruining your healing process!

4. Sleep in quality not quantity

During this window, your body produces the optimum amount of hormones needed for repair and fat loss.

Improving sleeping habits is the key to weight loss, building muscle, and living a healthy life in general. This important factor is often neglected in weight loss programs, perhaps being the missing piece you need! Good sleep is supposed to ensure proper adaptation of key hormones to burning fat, and may be even more important than increasing your workouts at the gym. Set a consistent bedtime and be sure to get to bed about 30 to 60 minutes earlier.

16/8 Intermittent Fasting Diet Plan

  • By following this 16/8 Intermittent Fasting diet plan, you fast for 16 hours and limit your eating to an 8-hour eating window.
  • It is really up to you whether you will decide to restrict yourself from eating for 16 hours out of 24 hours. You can choose the dining window from 8 a.m. to 4 p.m., 10 a.m. to 6 p.m., 8 p.m., or any time as long as it’s not 16 consecutive hours.
  • Most people who follow an Intermittent Fasting diet schedule prefer to skip breakfast instead of dinner, but different people have different rhythms of life.
  • The best part is that out of 16 hours, you will probably be sleeping at least 7-8 hours, so we are really talking about 9-8 hours of fasting every day.
  • It is also worth noting that we believe that the Intermittent Fastening 16/8 method is the most durable and easiest to start.

Sample Intermittent Fasting Meal Plan On Fasting Day

On each fasting day, you will have two meals and two snacks. Women will eat 500 calories per day, while men 600 calories per day. Men only need to double the snack portion to get the required number of daily calories.

On all fasting days, permitted beverages are limited to water, unsweetened hot or iced tea, and black coffee.

Tips to Survive Intermittent Fasting (IF)

Some people can go 24 hours or more without food, but for others, less than six hours is a real struggle. If you’re in the latter group, that doesn’t mean IF isn’t for you. There are a few ways to help you cope.

  1. Stay Hydrated – Sometimes your bodies interpret dehydration as hunger. You can feel those hunger pangs and think, ‘Oh, I need to eat something’. Sometimes all you have to do is take a few sips. Drink plenty of water during the fast. You can also drink black coffee, black tea, sparkling water and other zero calorie beverages.
  2. Keep busy – Have you ever been hungry at work but haven’t had a chance to eat? Often, when you finally get a chance to eat, you’re not starving. You can replicate this by staying busy. Remember, hunger comes in waves.
  3. Give it time – sometimes we get very impatient, especially when it comes to losing weight. We diet or exercise for two days then we check the scale and mirror to see the ‘big change’ and then we get frustrated. What happens when you get frustrated? You fall off the wagon. If you want to go anywhere with Intermittent Fasting (IF), you have to time it. First, give the eating pattern time to work wonders on your body. You just need to keep going, and the change will show itself.
  4. Give your body time to adapt to the Intermittent Fasting (IF) – you stop eating six meals a day every day. Your body may react differently now that it has to eat less food. Hunger, headache and sometimes body weakness are among the discomforts you may experience. Don’t give up! Use logic though.

Proven Health Benefits of Intermittent Fasting (IF)

Research shows that Intermittent Fasting helps extend life, regulate blood sugar, manage cholesterol, burn fat, and more. The benefits of Intermittent Fasting are well documented in helping people look better, feel better, control weight, and live healthier and longer.

The Intermittent Fasting (IF) reduces body fat and weight, blood lipids (triglycerides and LDL cholesterol), blood pressure, cancer risk, inflammation, oxidative stress.[1]

Intermittent Fasting increases fat burning, metabolic rate, cellular repair (autophagy), growth hormone release.[2]

The Intermittent Fasting improves appetite control (through changes in ghrelin), heart function, blood sugar, effectiveness of chemotherapy (allowing for higher doses more often).[3]
