how healthy is a liquid diet for weight loss?

Losing weight often comes down to finding the right balance between diet and exercise. If you exercise regularly, you can avoid focusing less on diet. 

However, for those who are already overweight or are gaining weight as a result of not exercising enough, following a nutritional and low-calorie diet could be the best way to help support their weight loss goals.

But what type of diet is best for weight loss? Is a liquid diet right for you? And is dieting really the healthy way to lose weight?

For answers to all of these questions and more, you have come to the right place!


What Is A Liquid Diet? Is It Healthy?

There are many types of diets one can follow to aid weight loss. However, in this article, we will focus on liquid diets, what they entail, and whether they are healthy. 

A liquid diet, as the name suggests, refers to not eating any solid meals at all, for a specific period. Instead, for nourishment, you are only allowed to drink fluids, such as vegetable and fruit juices, water, protein shakes, milk, yogurt, puddings, soups, broths, coffee/tea, and smoothies. 

As these liquids have very low calories and fats they can be very effective at helping to lower weight quickly in the short run.

Liquid diets are also considered healthy if used correctly. With the right combination of meals in liquid form, you can achieve the necessary vitamins, minerals, calories, protein, and nutrient intake your body needs to stay nourished and active.

However, it is highly recommended that before opting for a liquid diet program you speak to your doctor or dietician. These experts can help guide you on how to best follow a liquid diet program based on your health requirements and Body Mass Index (BMI).


3 Liquid Diet Ideas For Weight Loss

A liquid diet can be effective for weight loss and help cleanse and detoxify the body and improve digestive health. 

While there are many types of liquid diet ideas for weight loss that you can follow, most of these diet programs fall under the following three categories:


Cleansing & Detox Liquid Diets

This form of liquid diet focuses on consuming liquids such as juices, soups, and tea to remove toxins from the body. 

A detox diet isn't meant for weight loss but rather to help improve your immune system and eliminate toxins that can weaken your body. As such, this diet is only followed for a short period, a few days at the max!

Examples of detox and cleansing diets include water fasting, the master cleanse, and different types of vegetable and fruit juice diet programs.


Liquid Meal Replacement Diets To Aid Weight Loss

Those who find it difficult to control portion size or limit the frequency of meals they consume can potentially benefit from a liquid meal replacement diet that, as the name suggests, replaces certain meals with a low-calorie drink such as a shake or smoothie.

Having fresh juice or a smoothie blended with vegetables and fruits for breakfast, and/or soups and broths for lunch or dinner, can provide vital nutrients that are healthy for your body but are very low in calories. 

This helps you to cut down on calorie intake without reducing the number of times you eat and puts a stop to those frequent hunger pangs. This makes liquid meal replacement diets extremely effective for weight loss.


Medically Prescribed Liquid Diets

These types of liquid diets are generally prescribed by doctors to patients who are diagnosed with digestive problems, have trouble swallowing or chewing, have to undergo jaw surgery, have severe throat or mouth sores, and/or recovering from gastrointestinal infections, dental or oral surgery, as well as, weight loss surgery

There are generally two types of medically prescribed liquid diets; clear liquid diets and full liquid diets.

The biggest difference between the two is that a clear liquid diet only allows for the consumption of clear liquids such as water, broth, and apple juice, while a full liquid diet is less restrictive and allows for most types of beverages, protein shakes, and even foods that melt such as ice-cream, pudding, and Jell-O.

While medically prescribed liquid diets can result in weight loss, their main purpose is to make digesting food easy for patients.


The Pros & Cons of Liquid Diet Programs

Before opting for any type of liquid diet program it is first important to understand its benefits and drawbacks.

all liquid diet beverages

The Benefits of Liquid Diets (Pros)

  • Liquid diets have a much lower calorie count than solid foods (over 50% less). This means your body will likely burn more calories than you are consuming resulting in weight loss.
  • A well-planned full liquid diet can contain most if not all the vitamins, minerals, and nutrients your body needs daily while being low calorie and low fat. This can help with both weight loss and weight management.
  • Assists with organ and body detoxification. Following a liquid diet helps flush out your kidney and cleanse your digestive tract and other organs from unwanted toxins that could negatively impact your immune system. 
  • Liquid foods are easier to absorb for your digestive system and easier to excrete. Many consider following a liquid-only diet for a few days, intermittently, to help cleanse the digestive system and improve digestive health.
  • Liquid meal replacement diets are easy to make, easy to manage, and highly convenient as you can have nutrient-rich low-calorie meals on the go. 

The Drawbacks of Liquid Diets (Cons)

  • Following a clear liquid diet, for example, won’t give you all the calories or the vital nutrients your body needs to function normally. This can result in one feeling lethargic, light-headed, and dizzy.
  • Liquid diets can’t be sustained for the long term. These diets are best used only for short-term weight loss goals. At most, you should follow a liquid diet program for up to 5 days.
  • Staying on a liquid diet for too long can lead to malnutrition, fatigue, heart problems, constipation, and generally weaken the immune system.

Best Tips To Follow When On A Liquid Diet

Even if you are considering following a full liquid diet for a couple of days to assist with your weight loss goals, you still need to be prepared for the challenges you are bound to face.

To help you follow a liquid diet responsibility here are some top tips and considerations you should always account for.


Prepare & Plan Ahead

Following a liquid diet shouldn’t be a whimsical decision. If you are going to take this challenge on you need to be ready for it. Hence, you must plan ahead by preparing and stocking up on liquid meals in advance. 

By investing in a blender you can make big batches of liquid foods that you can freeze. This way whenever you feel hungry you don’t have to worry about finding or making something to drink.


Budget Accordingly

Relying solely on nutritional shakes that can be bought off-the-shelf, or buying ready-made juices and meal replacements can get quite expensive. 

Ideally, you want to create a balance of homemade liquid foods and store-bought shakes and smoothies to give you the nutrition and protein you need without it being burdensome on your wallet.


Turn Soft Foods Into Liquids

You don’t have to rely on just shakes and juices for calories and nutrients. You can also turn a variety of soft foods into liquids by simply adding water or milk. 

Heating certain foods until they melt, such as cheese, ice cream, or chocolate is also a great way to expand your liquid food options.

Don’t be shy of using a blender to puree as many fruits and vegetables as you can. This puree can be used in a variety of liquids adding not only flavor but also essential nutrients, minerals, and vitamins. 

You can also liquidate pasta, rice, and potatoes by boiling them until they are extremely soft and then blending and thinning them further with butter, water, or gravy.
