A liquid diet meal plan is a short-term diet routine where you get all the nutrients that you can from liquid foods or those that are liquid at room temperature.
Most individuals will practice a liquid diet for medical reasons, but some attempt it to lose weight, to aid digestion, or for “detox purposes.”
However, weight loss tends to be temporary; a healthy digestive system requires more fiber than a liquid diet can provide, and the body already detoxes itself naturally.
It’s best to only use this diet for medical reasons and under the supervision of a healthcare provider.
The liquid diet includes the following:
- Clear Liquid Diet: Comprises only clear, easily absorbed liquids that do not leave digestive residue. Examples include clear juices such as apple, white cranberry, clear sodas, gelatin, and water. Anything that is not clear does not fit into this.
- Full Liquid Diet: Includes clear liquids and other liquids such as milk, pureed and strained soups, smoothies, yogurt, pudding, milkshakes, and vegetable juices.
What Is A Temporary Liquid Diet Meal Plan?
A temporary liquid diet meal plan is a short-term, usually 1-7 day, routine where you only consume liquid foods or follow a diet for medical or lifestyle reasons.
Some of the benefits of a temporary liquid diet plan might include the following (3):
- Recovery: The most common reason for a temporary liquid diet is to allow the digestive system to recover from an illness, injury, or surgery.
- Weight Loss: Liquid diets can lead to reduced calorie intake. This calorie deficit can lead to weight loss. Healthcare providers may use calorie-controlled liquid diets to help patients lose weight rapidly in preparation for surgery. However, this weight loss is usually temporary, and you are likely to regain it once you resume your regular eating habits.
- Increased Intake of Certain Nutrients: Individuals who adopt diets like this for lifestyle reasons often emphasize the consumption of fruit and vegetable juices.
Fruits and vegetables, as you know, have high amounts of various nutrients, including vitamins (A, C, and K), minerals (such as magnesium, potassium, and folate), and are also rich in antioxidants. However, at the same time, liquid diets tend to be low in or lacking specific other essential nutrients, such as protein, fiber, healthy fats, and others.
Is A Liquid Diet Safe?
A liquid diet is safe when it is short-term and when supervised by a doctor.
If you aren’t going beyond 7 days, it can be safe.
It is essential to understand that the liquid diet is for short-term use, and therefore, it is not a long-term solution.
For instance, if you want to lose weight, this is not a long-term strategy, as it can only help you lose a few pounds in the few days you are on it, and you are likely to regain the weight once you start eating solid foods again. We recommend using the liquid diet solely for medical reasons in the short term, under the supervision and approval of a healthcare provider.

What Are The Rules Of A Healthy Liquid Diet?
While a liquid diet can be helpful in specific, short-term circumstances, it is crucial to understand that not every liquid is beneficial or essential.
You should always keep the following rules in mind when you are on this particular diet plan:
- Don’t over-reli on sugary liquids
When on a liquid diet, you need to avoid over-reliance on sugary liquids alone.
Ensure you have a balanced diet to avoid raising your blood sugar without getting the necessary nutrients your body needs. Sugary liquids, such as sodas and other sweetened drinks, may offer little nutritional value and contain empty calories.
Many of them are also carbonated, which you may need to avoid depending on your medical situation.
- Balance Your Nutrients
Ensure that your drinks have all the necessary nutrients that your body needs.
Consider liquids with enough protein, healthy fats, vitamins, minerals, and other essential nutrients. Nutritional shakes can help meet your dietary needs if you are on a full liquid diet.
- Keep Hydrated
It is also essential to ensure you drink enough water while on a liquid diet.
Most people will get plenty of fluids on a liquid diet, but still pay attention to thirst and hydration cues like you usually would.
- Consider Calories
Depending on your reasons for being on the diet and goals, you may need to make an effort to either increase or limit calorie intake. In either case, you can select liquid diet recipes with ingredients that align with your needs.

Can I Lose Weight By Eating A Liquid Diet?
Yes, you may lose weight by eating a liquid diet. It is essential to understand that most liquid diet foods, especially the clear liquids, are low in calories.
Therefore, living on a liquid diet means living on a calorie-deficient diet.
What happens when your body is in a calorie deficiency?
It breaks down stored energy, and hence you start losing body fat (and possibly muscle), resulting in a reduction in body weight.
If you are on a liquid diet for weight loss, you are definitely eating fewer calories and creating a calorie deficit. A liquid diet is one of the very low-calorie diets where you consume as few as 800 calories per day. That could cause a reduction of about 3-5lbs of body weight per week (2). However, there is a high likelihood of weight regain when it is lost rapidly or with an extreme calorie deficit.
How To Start A Liquid Diet Correctly?
It is essential to understand how to engage in a liquid diet to meet your body’s needs and avoid the potential adverse effects. Without a safe way of doing it, you might experience fatigue, dehydration, and weakness caused by nutrient deficiency.
These steps can be a good approach to doing it:
Understand Your Goals
First, it is essential to understand the reasons behind your engagement. Is it to recover from an illness or injury, prepare for surgery, or lose weight temporarily? This clarity will determine how you approach your diet.
Understand the Types
To better plan a liquid diet that yields the desired results, it is essential to understand the various types of liquid diet meal plans. As we have mentioned, there are two main types: the clear liquid diet and the full liquid diet.
Keep it Balanced
You need to ensure that your liquid diet plan is as balanced as possible to avoid the nutrient deficiencies that could occur. Especially with a full liquid diet, try to make sure there is enough protein, healthy fats, vitamins, minerals, water, and complex carbs, among other nutrients. Protein shakes can help ensure a high-protein liquid diet.
Make it Short
Keep the duration of your diet short, typically 1–7 days.
This duration can be safe for healthy individuals. For medical reasons, you will always be guided by your doctor on the best liquid diet for weight loss that fits your needs and health requirements. If you are on a liquid diet for a bit longer, you should consult a healthcare professional.
Your doctor most likely won’t recommend a 30-day liquid diet weight loss plan.
Eat More Frequently
You may need to drink liquids more frequently in small portions than fewer times in large portions. So, instead of having 3 large drinks a day, you might have 5-6 small portions per day.
What Foods To Eat On A Liquid Diet?
There are several foods that you can eat on a liquid diet plan.
If you’re looking for liquid diet ideas, this section provides foods that include both clear liquids and full liquids.
We can categorize the foods as follows:
- Clear Liquid Diet: Drinks include water, clear broths, and clear fruit juices, such as apple, white grape, and cranberry, without pulp.
- Full Liquid Diet: Milk, cream soups with no solid chunks, fruit juices with no pulp, plain or smooth yogurt, vegetable juices, and shakes and smoothies.

What Is An Example Of A Liquid Diet Meal Plan?
Here is an example of a 3-day liquid diet meal plan that you can adapt, adjust, or make to suit your personal goals. Of course, you may extend it if you are doing a liquid diet for more days:
1-Day Liquid Diet Meal Plan Example:
- Morning: Warm water with lemon or green tea.
- Breakfast: Smoothie – a banana blended with a cup of low-fat milk and peanut butter.
- Mid-Morning: Clear chicken or vegetable broth.
- Lunch: Creamy tomato soup (strained).
- Afternoon: Protein shake (milk and protein powder with strained berry juice).
- Evening: Warm milk with honey.
- Dinner: Pureed bean or lentil soup.
How Long Is It Safe To Follow A Liquid Diet?
It depends on the type of diet. For instance, guidelines recommend a maximum of 3–4 days on a clear liquid diet for healthy individuals (1). For a full liquid diet, there is no set duration, but it requires the supervision of a healthcare provider to ensure safety.
While that is the case, it is vital to keep it short-term since long-term liquid diets can lead to muscle loss and other health issues. Practicing the liquid diet for 1-7 days can be okay for healthy individuals, or as directed by your healthcare provider.

How Much Weight Will I Lose On A Liquid Diet?
As mentioned, a liquid diet is a short-term guide to eating, and experts do not recommend it for long-term weight loss benefits.
However, that short period can result in some temporary weight loss.
The amount of weight you can lose depends on several factors, including your initial weight, activity level, and metabolic rate, among others.
A liquid diet, such as clear liquids, is low in calories; therefore, consuming only these liquids will create a calorie deficit for the entire period you are on it. That means your body will burn more stored energy, hence leading to a reduction in body weight.
The exact amount of weight you can lose on a liquid diet plan for weight loss depends on several factors, among which we have mentioned. Most very low-calorie diets, including liquid diets, involve consuming as few as 800 calories a day, which can lead to a 3-5-pound weight reduction per week (2).
However, you will likely regain the weight when you start eating solid foods again because the diet is unsustainable for lifelong progress.
2 weeks of liquid diet is not safe and not recommended for most individuals due to nutrient deficiencies. However, if medically supervised, it can be safe and necessary in certain situations. It is important to note that if you prolong without proper or careful management, it may lead to fatigue, muscle loss, or other health issues. Whether or not you feel hungry on a liquid diet depends on how the liquid diet is planned. Of course, you can feel hungry if the diet is largely on clear liquids. However, a well-planned full liquid diet might leave you satisfied and feeling less hungry because it can be well-balanced with protein, healthy fats, carbohydrates, and sufficient calories. Yes, yogurt that is smooth and doesn’t contain seeds or fruit chunks is part of a full liquid diet because it is soft and easy to swallow. As long as the yogurt is soft and free of solid additives, it is suitable for this diet plan. Frequently Asked Questions

The Bottom Line
As we have learned, a liquid diet plan is a temporary, structured eating plan that involves consuming only liquid foods for a specified period, as outlined in the plan.
It could be 1-7 days and hence is not a long-term strategy. In this plan, you can only consume clear liquids or follow a full liquid diet, depending on the recommendations of the doctor or what you aim to achieve.
This liquid diet plan offers short-term weight loss and can be used medically to prevent significant weight loss when normal eating isn’t possible. Some use it for digestion, “detox,” and other health benefits.
