Benefits of fasting

Imagine being able to boost your metabolism, feel more energized, and gain a variety of health advantages without having to track your calories or adhere to a strict diet. Here are just a few advantages of fasting. With all the diet advice out there, not eating might be the simplest, which is what makes fasting seem so novel. Naturally, fasting is not the same as starving yourself, despite what many people believe it to be. Fasting, however, is not a diet either.

To fast literally means to refrain from eating and drinking for a set amount of time. Since many religions practice spiritual fasting, it has been practiced for thousands of years. I prefer to view it in this context as merely a change in eating habits. You have a specific window of time when you eat, whether it’s a few hours per day or certain days of the week, as opposed to three full meals a day or a number of smaller meals spread out throughout the day. You are free to eat whatever you want during that time, provided it is reasonable.

It’s unlikely that eating processed foods and potato chips will allow you to benefit from fasting. If that describes you, I advise you to look at your diet before attempting a fast. You will experience changes if you fast regularly and eat a diet high in whole foods, such as fruits, vegetables, lean proteins, healthy fats, and raw dairy. In addition, occasional indulgences in chocolate or cheese won’t have as much of an impact as they would if you were on a calorie-restrictive diet. The fact that there is no one “correct” way to fast makes it beautiful. In actuality, there are many well-liked varieties and many advantages to fasting.

Benefits of Fasting

  1. Promotes Loss of Weight

Studies have shown that fasting is an effective weight-loss strategy. In a 2015 study, it was discovered that whole-day fasting could reduce body weight by up to 9% while alternate-day fasting could reduce it by up to 7%. Another study, this one from the University of Southern California, found that 71 adults lost an average of six pounds, reduced inflammation levels, and their waistlines, and lost total body fat without losing muscle mass when they underwent a five-day fast (eating between 750 and 1,100 calories per day) once every three months. Fasting, even sporadically, maybe the key to losing weight and belly fat.

  1. Encourages HGH Secretion

Although it is produced by the body naturally, human growth hormone (HGH) only has a short half-life in the blood. It has been used successfully to treat obesity and to increase muscle mass, which is crucial for fat burning. Fasting also increases HGH secretion. Additionally, HGH promotes muscle growth, which can enhance your workouts. When you combine these, you have a powerful tool for burning fat.

  1. Might Improve Sports Performance

Professional athletes who fast have shown improvements in their body mass and other health metrics. This is due to the fact that, as was already mentioned, it can efficiently aid in shedding extra pounds while maximizing muscle growth because it produces HGH.

In order to simultaneously build muscle and lose fat, athletes are traditionally advised to consume high-quality protein 30 minutes after their workouts are over (post-workout nutrition). On training days, it is recommended to fast; however, eating is encouraged on game days.

  1. Aids in restoring normal insulin sensitivity

Your body may develop insulin resistance if it consumes too many carbohydrates and sugars. A variety of chronic diseases, including type 2 diabetes, are frequently made possible by this. Maintaining your body’s insulin sensitivity is crucial if you don’t want to take this path. Fasting is a useful strategy for achieving this. In adults with type 2 diabetes, intermittent fasting improved important markers like body weight and glucose levels, according to a study published in the World Journal of Diabetes. In another study, it was discovered that caloric restriction and intermittent fasting both reduced visceral fat mass, fasting insulin, and insulin resistance.

  1. Maintains Healthy Ghrelin Levels

Ghrelin definition. Because it is in charge of alerting your body to hunger, it is also referred to as the hunger hormone. Actually increasing ghrelin production during a diet or extremely restrictive eating pattern will make you feel more hungry. Even though you may find it difficult the first few days, fasting actually aids in returning ghrelin levels to normal.

You’ll eventually stop feeling hungry just because it’s mealtime. Your body will instead become better at recognizing when it actually needs food.

  1. Can Reduce Triglyceride Levels

Your triglyceride levels may soar when you consume an excessive amount of bad cholesterol, raising your risk of heart disease. In fact, intermittent fasting lowers triglycerides while lowering levels of bad cholesterol.

  1. Aids in delaying the aging process

Studies on rats appear to link intermittent fasting with longer life, though more human studies are required. In one study, it was discovered that rats with intermittent fasting had lower body weights and lived longer.

Despite being heavier than the non-fasting mice, another study found that a group of mice that intermittently fasted lived longer than the control group. The results are encouraging, though it’s not certain if they would occur in humans. There is actually a ton of proof that it can actually slow the effects of aging and increase longevity.

Fasting Methods

Intermittent fasting

Cyclical fasting is another name for this style of fasting. A general term for eating (and not eating) sporadically is intermittent fasting. In fact, intermittent fasting is practiced in almost all of the ways listed below!

The typical duration of an intermittent fast is between 14 and 18 hours. The maximum amount of time that any of these plans could ask you to go without solid food is between 32 and 36 hours.

Time-Restricted Consumption

When you engage in time-restricted eating, you go without eating for 12 to 16 hours. You are free to consume as much of your preferred healthy foods during your eating window. One of the most popular ways to fast is this.

The implementation of time-restricted eating is fairly easy. For example, if you finish dinner at 7 p.m., you wouldn’t have another meal until at least 7 a.m. The no-eating period can be extended if you so choose until around 11 or 12 p.m.

This is a good way to introduce fasting into your lifestyle and experiment without making any significant changes because you are sleeping for a significant portion of the “no eating” time.

Fasting on 16/8

You basically fast for 16 hours a day and then eat for the remaining eight, which is another name for time-restricted eating.

Fasting on alternate days

Alternate-day fasting, another form of intermittent fasting, entails severely limiting the number of calories you consume on fasting days while allowing yourself to eat as much as you want on non-fasting days. Food isn’t completely off-limits, but you limit yourself to about 25% of your daily caloric intake. For instance, someone consuming 2,000 calories would reduce their intake to 500.

Alternate-day fasting isn’t always a good long-term strategy because it can be hard to maintain, but it can be useful to start a good habit.

5:2 Diet

Except that you eat normally five days a week instead of two, it is very similar to alternate-day fasting. On the other two, daily caloric intake is capped at 500–600 calories.

A warrior diet

In this case, you’ll consume only fruits and vegetables during the day and a heartier, more substantial meal at night.

A Daniel Fast

The Daniel fast is a partial fast that emphasizes vegetables, fruits, and other healthy whole foods but abstains from meat, dairy, grains (unless they are sprouted ancient grains), and drinks like coffee, alcohol, and juice. It is based on Daniel’s experiences in the Book of Daniel of the Bible.

The majority of people observe this fast for 21 days in an effort to have a spiritual awakening, have more time to contemplate their relationship with God, or simply to feel more like Daniel would have felt in his day.

How to Fast

Are you prepared to try a fast? Here’s how to simplify it.

  1. Choose the type of fast you’ll perform.

I advise beginning with a 12-hour fast before introducing time-restricted eating. After a few days, if it still feels good, you can extend the fast to 14 or even 18 hours. I don’t advise continuing your fast beyond that.

Have you ever fasted? Then you might want to give a longer fast, like an alternate-day fast, a try.

  1. Make a few goals.

What are you hoping to achieve by fasting? gain more energy, feel better, and lose weight? During your fast, write it down and place it somewhere you’ll see it often.

  1. Plan a menu and fill the refrigerator.

Decide when you’ll eat and what you’ll eat at that time before your fast starts. Knowing this in advance relieves stress, particularly if you worry that you might eat everything you see “just because you can.”

You may find that planning meals in advance is unnecessary as you get more accustomed to fasting, but I find that having a variety of healthy food ready for me in the fridge makes fasting much easier.

  1. Be aware of your body.

It may take some time for your body to adjust to fasting as it sheds old habits and forms new ones, but it’s crucial to pay attention to your body’s needs. If you’ve been fasting for 16 hours and you still feel like you need a snack, have one. Wait until you are hungry if your fasting period has ended but you are not yet hungry.

There are no unbending laws in this situation. You aren’t “messing up,” though. It might be beneficial to write down a sentence or two about your feelings every day. You might discover that certain types of fasts suit you better at particular times of the month or year.

How long should you fast?

Although the typical intermittent fast ranges from 14 to 18 hours, as I mentioned earlier, there is no set time limit for fasting. It’s better to keep in mind a few things about fasting rather than focusing on how long you should fast:

You should eat something if you’re actually hungry. If you don’t, you’ll be stressed out about being hungry, hungry and stressed, and possibly even angry.

Wait a little while before starting a fasting regimen if you’re just starting to eat healthier and choose whole foods so you don’t have anything else to worry about. Prioritize consuming whole, healthy foods first.

Are you preparing for a major competition, such as a triathlon or marathon? It’s probably not a good idea to try fasting right now. Consult your doctor and coach first.

Again, pay attention to your body!

Risks and Negative Impacts

Although the health advantages of fasting are very alluring, I do want to emphasize that it isn’t always a good idea. Patients with diabetes and hypoglycemia should probably refrain from fasting until their insulin and blood sugar levels have returned to normal.

Women who are pregnant or nursing should under no circumstances fast because it may harm the unborn child.

Additionally, it’s best to speak with your doctor about incorporating fasting into your lifestyle if you take particular medications or have other medical conditions. However, for the majority of people, it can be a really useful tool for controlling your weight and overall health.

Final Reflections

  • A change in eating habits is fasting. You have a window of time to eat rather than fixed meals and mealtimes.
  • Fasting can take many different forms. The most popular umbrella term for a variety of eating patterns, including alternate day and time-restricted eating, is “intermittent fasting.”
  • Making decisions about the kind of fast you’re doing, what you hope to gain from it, and preparing your fridge with the foods you’ll eat will all help make the fast successful.
  • Fasting has numerous health advantages, including improved weight loss, normalized insulin sensitivity, and perhaps even a slower aging process.
  • While most people can benefit from fasting if you’re expecting or nursing, you should completely avoid it. It is best to speak with your doctor before beginning a fast if you have diabetes, a serious medical condition, or take prescription medication.
