14-Day Liquid Diet: The Extreme Diet Plan You Need To Know

You might have also seen someone demonstrate 14-day liquid diet weight loss results that grabbed your attention.

So, before starting on a 14-day liquid diet, here’s what you should know.

Are the 14-Day Liquid Diet Weight Loss Results Worth It?

Weight loss is a source of frustration for many people.

There are so many diets promising tremendous results that it’s difficult to know which one is effective.

What makes it even more perplexing is that everyone’s body is different, thus the weight loss outcomes vary widely.

What works for one person may not work for another.

One of the numerous diets that promise to help you lose 10 pounds in two weeks is the liquid diet.

Although incredibly restricting, it does work for some people.

You may have also seen someone show 14-day liquid diet weight loss outcomes that piqued your interest.

So, here’s what you should know before embarking on a 14-day liquid diet.

What Exactly Are Liquid Diets?

One of the most restricted eating programs is the liquid diet.

They should not be followed for an extended period of time, and 14 days is sufficient as any longer may result in serious problems.

A liquid diet consists of solely consuming liquids throughout that time period, however some people allow themselves 8 ounces of solid food per day.

The quantity of calories you need every day is determined by your weight, height, age, gender, and lifestyle.

If you wish to follow this diet, you’ll undoubtedly have a difficult time acquiring adequate nutrients.

During the two weeks, a nutritionist or personal trainer will ensure that your body receives all of the vitamins and minerals it requires to function correctly.

Soups, smoothies, and shakes are the mainstays of liquid diets.

While the liquid diet is often prescribed by doctors as a pre- or post-operative dietary regimen, some people use it just to lose weight.

How Effective The Liquid Diet?

These diets work by restricting your calorie consumption.

As a consequence, your body begins to burn the excess fat you’ve stored.

However, what many people don’t know about these diets is that there is no way to lose weight if you don’t burn more calories than you ingest.

No matter how many pounds of fat you burn in two weeks, the scale will not move in the manner you want it to until you consume fewer calories than you burn every day.

This is also independent of the kind of weight loss employed.

The explanation for this is straightforward: a liquid diet does not always imply a low-calorie diet.

Meal replacement shakes, for example, might include a lot of calories depending on the components (particularly those made at home).

It’s acceptable to have two or three of them each day because you’ll end up absorbing roughly 800-1200 calories if you don’t consume solid food.

However, consuming too many shakes and exceeding your typical calorie intake might be detrimental to your weight loss goals.

It is advisable to engage in an exercise regimen both during and after the diet phase to achieve the best outcomes.

This allows you to burn significantly more calories while also aiding muscular growth and shedding body fat.

Many people regain their weight after finishing these diets because they do not keep to a healthy eating habit.

What Is the Outline of a Liquid Diet Plan?

A liquid diet is the most straightforward and straightforward method for rapid and effective weight loss.

A liquid diet is prescribed by doctors for those who have digestive issues, need surgery, or are recovering from trauma.

While the diet may not be suited for long-term weight loss, it does act as a very excellent means of detoxifying your system, which kick-starts the weight loss process.

How Can a Liquid Diet for Weight Loss Helps to Weight Loss?

When it comes to losing weight, many people opt to a liquid diet.

One of the primary reasons why people choose the liquid diet for weight loss above all other diets is that it saves time, promotes improved metabolism, helps the digestive system, detoxifies the body, and improves general health while also causing weight loss.

What makes a liquid diet for weight loss so effective?

Liquid diet meals are low in calories and perform better than any other low-calorie diet.

When we consume less calories, our bodies begin to use stored fat or glycogen as a fuel source, which results in weight loss.

The body fat ratio decreases as well, resulting in rapid and effective weight loss.

Another advantage of a liquid diet is that the foods that are turned into liquid form (raw or cooked) are extremely nutritious.

In addition, substituting meals with low-calorie liquid foods improves body composition metrics.

A liquid diet consists mostly of low-calorie meals such as fruits and vegetables, which are also high in all the essential elements that our bodies require to function properly.

A liquid diet chart includes items in liquid form (juices, smoothies, shakes, broths, and soups).

These meals are beneficial to your digestive system.

They are beneficial not just to digestion, but also to absorption and, eventually, elimination.

Furthermore, the liquid diet’s dietary fibers and water might help you stay fuller for longer.

According to studies, a conventional meal substituted with liquid foods provides more fiber than a solid meal.

The advantages of a 5-day liquid diet for weight loss;

  • Encourages detoxification.
  • If the items in your liquid diet are low in fiber, it might provide a much-needed reprieve for your digestive system.
  • Improves skin health.
  • Is beneficial for persons who have uncomfortable wisdom teeth issues.
  • It aids in the relief of stomach ulcer discomfort.
  • Is an excellent alternative for persons who have had stomach surgery, since it aids in the gradual transition to solid meals following the procedure.

Different Types of Liquid Diets

An all-liquid diet may take numerous shapes, depending on what you drink and how frequently you follow it.

Fasting on Water

Fasting for three to five days by drinking just water or a combination of water and occasionally herbal drinks without sugar is possible.

This diet is intended to cleanse your body from inside, but if you aren’t used to it or don’t know how to water fast, you may feel exhaustion and nausea.

Water fasting weight loss is frequently brief since most people are unable to stick to this diet long enough to shed large amounts of weight and keep it off.

Fasting on Alternate Days

The Liquid Diet

Alternate day fasting is a more relaxed strategy that permits people to consume fluids on alternate days while eating solid food on the remaining days of the week.

It’s a wonderful idea if you want to keep up with your regular routine while suffering less hunger sensations, which are common among individuals who follow a water fast.

This diet is more adjustable since you may choose to consume only clear liquids (broth, juices, teas, and water) on fasting days or meal replacement shakes that include more nutrients and are more filling.

Liquid Meal Replacement Diet

Meal replacement liquid diet is replacing your meals with protein drinks.

If you are overweight, this may be a good option for you because it provides rapid results (up to 10 pounds in 2 weeks!) with little effort.

Protein smoothies on this diet can be purchased or produced from scratch.

Because these products are high in protein, they aid in weight loss by suppressing hunger while maintaining a steady metabolism.

Diet of Clear Liquids

The Liquid Diet Plan

The clear liquid diet is the most limiting.

Unfortunately, it’s also the most popular among those who want to loss weight as quickly as possible.

It entails drinking solely clear beverages over a period of time.

Shakes and smoothies containing grains and other foods are not permitted on this regimen.

Only juices, tea, clear broths, and water are permitted.

Advantages of Liquid Diets

Despite their severe character, these diets will provide you with preliminary results.

Here are some advantages to following a liquid diet plan:

Loss of Weight

Liquid Diet

If done correctly, in a healthy manner, and in conjunction with exercise, an all-liquid diet can help you lose weight rapidly.

While you should utilize them to reduce your calorie intake, you should still consume enough to provide energy for everyday activities and exercise.

You should also ensure that you are getting all of the nutrients your body requires.

It’s more difficult to do so during water fasts and liquid detoxes, but it’s simpler to do so during meal replacement liquid diets.

Begin Eating Healthily

Free Liquid Diet Plan

When you’re attempting to cut out particular food categories as part of an elimination diet, or if you just want to clean up your diet, going on a liquid diet can assist.

After a few days of simple liquids, you may begin reintroducing nutritious meals while avoiding processed garbage.

Simple And Low-Cost

Liquid Diet Plan

Is there a diet that is less expensive than one that requires you to drink just water?

Most liquid diets are quite inexpensive and need less preparation and cooking than other types of diets.

Weight loss Outcomes With a 14-Day Liquid Diet

Many people’s ultimate objective is to lose weight quickly.

For such persons, a two-week (14-day) liquid diet for weight loss is recommended.

The main goal of the diet is to limit your calorie consumption so that your body can begin to burn the excess fat that has been deposited.

To achieve the finest outcomes, you should also engage in workouts to enhance your efforts.

This manner, you’ll not only lose weight but also help your muscles grow.

One of the most significant benefits of following a 14-day weight loss plan is that it is inexpensive and produces immediate results.

When it comes to losing weight, you should take it one step at a time.

This way, you won’t have to weigh yourself every other day, and you’ll be more likely to stick with good lifestyle choices and not give up quickly.

Liquid diets are designed to replace all or part of your meals with liquid foods.

People choose liquid diets to lose weight since they are low in calories and nutritionally balanced.

Although balanced, a liquid diet allows you to consume some of the best foods, such as fresh fruits and vegetables, low-fat dairy products, lean protein meals, whole grains, water, and other sugar-free drinks, but in liquid or semi-liquid form.

The liquid diet recipe does not specify meal or snack timings, so you may substitute meals anytime you choose, with the main goal of tying you to a liquid meal eating schedule.

What Exactly is the Pre-Bariatric Surgery Liquid Diet?

The Pre Bariatric Surgery Liquid Diet is nothing more than a liquid-based Low Carbohydrate, Low Fat, High Protein diet.

It is advised to limit your daily calorie intake between 600 and 1200.

Regardless of the kind of bariatric treatment performed, all patients must follow a two-week pre-op liquid diet.

The prospect of drinking just liquids for two weeks may be terrifying.

However, we hope that this blog will educate you about the goal of the liquid diet, the hazards of not sticking to the diet, and how to adhere to the diet.

So grab a drink and a seat; let’s get started!

As a bariatric dietician, I understand how tough it may be to even consider giving up solid foods in order to prepare for weight loss surgery.

I’ve watched many patients struggle during the last two weeks, and I truly feel for them.

However, contrary to popular belief, this is not intended to torment you!

In fact, to reduce the danger of the treatment, we require patients to drink only liquids before to surgery.

The Bariatric Pre-Op Liquid Diet’s Goal

Many individuals will have extra fat around and/or in their liver prior to surgery.

The surgeon must relocate the liver in order to reach the stomach and undertake the bariatric treatment.

The bigger the liver is, paired with the fat in and around it, the more difficult it is for the surgeon to navigate safely and successfully around it.

This can result in the patient being under anesthesia for a longer period of time, considerably increasing their risk of problems, not to mention their medical expenditures.

Patients lose enough weight on the two-week liquid diet to shrink the liver and reduce the amount of time the surgeon has spend moving around the liver.

Why is Liquid Diet Applied Before Bariatric Surgery?

Reason #1 Weight Loss

Most patients will drop 10-15 pounds on average while on the Pre Bariatric Surgery Liquid Diet. Remember that the main reason you’re having bariatric surgery is to lose weight.

This diet’s Low Carbohydrate, Low Fat, High Protein, Low-Calorie characteristics will kickstart that process for you.

The more weight you can shed before surgery, the better.

Weight loss surgery is always easier and has a lower complication risk in slimmer people.

As a result, any weight decrease prior to surgery is usually appreciated.

The number of pounds you will drop is determined on your starting weight.

The more weight you should lose, the more weight you should shed.

It also depends on your gender. Male patients often lose more weight than female ones.

This is especially true for women in their golden years.

Muscle is the body’s calorie-burning mechanism.

Males, on average, have greater muscular mass than females and, as a result, a higher metabolism.

Furthermore, as you age, part of your muscular mass is lost.

To shed a considerable amount of weight, older patients must labor more.

Exercise can help you succeed before and after bariatric surgery.

That brings us to reason number two.

Reason #2 Maintaining Lean Muscle

It’s nearly hard not to lose muscle mass when losing weight quickly.

This is especially true following bariatric surgery.

Malabsorption treatments, such as the Roux en Y Gastric Bypass and Duodenal Switch, are well known for this.

One of the primary ways that bariatric surgeons attempt to mitigate the problem is to increase protein consumption in the diet.

It all begins with a liquid diet.

Remember how I stated the Pre Bariatric Surgery Liquid Diet is high in protein?

Most bariatric surgeons would advise you to consume at least 60-80 grams of protein every day.

That value is connected to your weight and degree of activity.

If you train out frequently, you will require a greater protein concentration in your diet.

Consult your doctor and/or a nutritionist to determine how many grams of protein you should consume each day.

Patients with renal and/or liver illness should be cautious about how much protein they consume because it can be harmful to their health.

Before beginning the Pre Bariatric Surgery Liquid Diet, please discuss with your provider if you are on dialysis or have liver cirrhosis.

Many patients, particularly women, believe that in order to lose weight, they must spend numerous hours on a treadmill.

Cardio is obviously vital, but remember to mix it up.

Lift weights at least three times each week to maintain and develop muscular mass.

Work out the major muscular groups, such as the hamstrings and back muscles.

By alternating between aerobic and weight training, you may use muscle confusion to your benefit.

Extra weights may not be necessary if you are excessively fat.

Make use of your own body weight.

Squats, push-ups, pull-ups, jumping jacks, lunges, and other exercises may be performed just with your body weight.

Begin softly and progressively pick up the pace.

Remember that the most essential thing is to begin.

Excuses don’t help you burn calories.

Get started.

Reason #3 Reduce the Size of the Liver

The third reason is, in my opinion, the most crucial.

Your liver expanded in tandem with your weight gain. You acquire what’s known as a Fatty Liver.

The disadvantage of having a big liver during bariatric surgery is that your surgeon may be unable to complete the procedure.

Allow me to explain.

The stomach is situated beneath the liver.

During surgery, your bariatric surgeon will raise the liver to get access to the stomach, which he will then shrink to allow you to lose weight.

If your liver is very big, the surgeon may be unable to reach your stomach.

Prior to using the liquid diet, I had two patients during my residency at the University of Florida in Gainesville who underwent surgery that had to be canceled owing to a big liver.

It has been scientifically established that just two weeks on a Low Fat, Low Carbohydrate, High Protein, Low-Calorie diet would reduce the size of your liver by at least 25%.

So, don’t take the risk.

If you stick to the diet, your operation will most likely go off without a hitch.

Reason #4 Mental Awareness

You will continue the liquid diet after weight loss surgery.

There will be some adjustments, but for the most part, a liquid diet for the first 1-2 weeks following surgery is the standard of treatment.

After surgery, we want your staple lines and connections to heal properly.

You don’t want to eat solid food straight away since it will break one of these connections.

That might have a negative impact on your outcome.

Your diet will be gradually introduced over a 6-week period.

Please follow the instructions provided by your bariatric surgery program.

The liquid diet will educate you what to consume after surgery if you do it before surgery.

Hopefully, you gained mental awareness of your diet’s quantities, calories, and components.

One piece of excellent news.

Because you are unlikely to feel hungry after surgery, the liquid diet phase should be much simpler.

MUST READ  Low-Fat Diet: Fact or Fiction?

You want to maintain mental awareness or knowledge throughout the final phases of your diet following surgery.

The new eating habits will help you lose more weight, but maybe more significantly, they will help you keep the weight off.

Approximately 25% of people who have undergone bariatric surgery will recover part or all of their weight.

This is mostly due to a lack of Mental Awareness, as well as a lack of discipline or self-control. Bariatric surgery is only a technique for assisting you in losing weight.

You must commit to making the necessary changes. A shift in lifestyle.

Reason #5 Adaptability

I addressed it briefly above, but hunger is a problem early on in the Pre Bariatric Liquid Diet. Don’t be concerned; your body will ADAPT.

You will be hungry, particularly during the first several days of the Pre Bariatric Surgery Liquid Diet.

Your body is quite intelligent, and it will cease yearning all of the bad food you’ve been consuming.

The body loves sweets, drinks, or junk food because you give it to it.

If you quit drinking Coca-Cola or eating Krispy Kreme donuts, the cravings will go away in a few days.

Consider a cocaine addict; they desire cocaine because they feed it to their bodies.

Hopefully, you don’t want cocaine since you’ve never given it to your body.

If you sample it, you’ll want to have it again and again.

We are built to adapt. One of the key reasons humans are so good in so many things is because of adaptation.

We can adapt, pivot, and use our minds in a variety of beneficial ways.

Nutrition is no exception.

The diet will be difficult at first; every patient will tell me that the first 3-4 days are difficult, but they all survived.


Some of the more active patients will mostly complain of fatigue.

This is especially true if you are trying to keep inside a very low-calorie range.

If this is the case, you may need to gradually increase your calorie intake until you no longer feel weak.

Remember that you must provide fuel to the body in order for it to accomplish the duties that you require.

Use excellent fuel instead of CARBage.

During the two weeks, focus on protein to nourish your body.

Reason #6 Empty Stomach

I have a tale that will perfectly illustrate reason 6.

When I was a chief resident in 2009, I performed a laparoscopic sleeve gastrectomy alongside one of my mentors.

We handled the situation properly, and the patient had no problems, but a lot of things could have gone wrong for the patient just because he did not adhere to the diet.

During his operation, we noticed that the patient’s stomach was bigger and heavier than usual, yet we were able to partition the stomach without incident.

We performed a normal endoscopy at the conclusion of the treatment to assess the sleeve and check for leakage.

An endoscopy is a procedure in which a camera is sent into your mouth and into your stomach, allowing us to view the stomach from the inside.

We were surprised to find chicken bits between the staple lines.

Are you serious?

Right before surgery, the patient jeopardized his own life for a piece of chicken. Again, nothing bad occurred to the patient, but the takeaway here is don’t do it.

It isn’t worth it.

This patient was apparently a sleepwalker, and the night before the operation, he went to the fridge and ate some leftover Chinese cuisine with chicken broccoli.

True tale…

We require a clean stomach.

The presence of old food in the stomach increases the likelihood of difficulties.

It also increases the quantity of germs in your stomach, raising the possibility of illness.

It will also feel extremely wonderful to know that you put your best foot forward.

You did it, you did it.

Hunger did not win, and hunger did not determine your fate.

After all, it was the cause of your desire for weight loss surgery.

Demonstrate to your body that you are in command.

Tell your body that it’s time for a shift and that you’re in complete control now.

Reason #7 You Can Save Money

You will, indeed, save money.

Who doesn’t enjoy saving money?

Despite the fact that you will have to purchase the protein drinks of your choosing.

I realize they’re pricey, but you’ll avoid eating steak, chicken, and other higher-priced solid meals.

At the end of the day, you will have saved some money.

Shop around and use your imagination.

Look for bargains.

Choose one that appeals to you and stick to it.

You will use them for many weeks before to and following surgery.

So, in conclusion, I will say that the two-week Pre Bariatric Surgery Liquid Diet is not the most exciting part of weight loss surgery, but it is just as important as the surgery itself.

The liquid diet is governed by the restrictions of each bariatric program, so verify with yours.

We follow the guidelines provided in the liquid diet section in my program.

This text is only a guide; you are free to adapt it to your specific situation or preferences.
