Liquid diet

2 week liquid diet

2 week liquid diet

Most people go on diets because they want to lose weight, other people want to feel better and maybe get rid of the feeling of always being tired after heavy meals or having a poor night sleep. Good news is that a liquid diet has the potential to help with all of that, simply because it can lower the stress on your digestive system and free up all that energy that could be used for other purposes. You might not know this, but digestion takes up a significant amount of energy, especially for heavy meals.

It is obviously good to have a well explained and a simple to follow theory about the subject, which in this case is the liquid diet. Even more important it is to have a step-by-step guidance on how to begin to practise this diet. I have chosen 2 weeks as a transition period from a regular diet to a liquid diet, because as I think 2 weeks is enough for a mild and smooth transition to another diet. It is also a sufficiently quick switch to see the positive results and to avoid any chance of becoming disappointed by the lack of quickly visible results.

If you do not quite know what a liquid diet is in general and want to gain a deeper theoretical knowledge, then I suggest you read my other articles. The goal of these 2 weeks is to move to a fully liquid food eating mode, where all of your meals are either soups or smoothies (including juices, teas, water, etc). Besides the liquid diet you will see intermittent fasting added to the 2 week liquid diet plan, because they go together hand in hand. Most people can easily do intermittent fasting, it gives the body a good reset before starting something new. You could compare it to scrubbing off old loose paint before repainting your wall.

First 5 days as an introduction to the liquid diet

Rapid diet switching can be hard, especially mentally. Initially you can also feel physically weaker than usual because your body needs time to adapt to a new way of eating. Due to all of this, a smart transition to a liquid diet plan for the first 3 days, I suppose, should look something like the following:

Do a 14-hour intermittent fasting, preferably without any calorie-containing drinks. You can drink sugarless plain coffee, tea or pure water. If you can be without drinking at all, that is even more effective.
Replace 1 of your 3 meals with either a smoothie or a liquid soup.
Avoid eating too much sugary food, highly processed food, excessively fatty food (especially anything deep-fried), or very starchy food such as potatoes, pizzas, etc.

The goal of this first step is to get used to the new regime. Initially you can feel some physical discomfort – different people feel it differently, but you will quickly get used to it.

Days 6-10: continue and move to the next level

By now you are somewhat familiar with the process. You are getting used to doing regular short fasts and having one of your daily meals in a liquid form. All of this is really good, but it is only the beginning. If you want to see more serious results, a more serious approach is needed.

Here is what I think would be a good plan for the next 5 days:

Increase daily intermittent fasting time to 18 hours if you can. You can try 16 if you feel that 18 hours is too much.
Try to eat only twice a day and eat all your food within the time window between your fasts. No snacking or caloric drinks outside of that window.
On days when you feel that you can have both of your meals in a liquid form, do it. This will speed up the transition process.

This level is much more advanced than the previous one. By the end of it your body should be used to the new eating habits and you will likely start seeing positive physical and mental transformations happening to you. By knowing and being able to do 18-hour intermittent fasts, 2 meals a day and having them in a liquid form, you are now so unique that less than 1% of people do even remotely similar things. Slowly you will start to understand that this practice is much more efficient in shaping your body than any excruciating physical exercise.

Days 11-14: reaching even higher level

After the initial 10 days you should be quite used to the combination of intermittent fasting and a liquid diet. By now you are confident in knowing that you control this process and you certainly feel some good changes happening. The initial 10 days gave you the knowledge of how to use this tool if you wanted to lose weight, improve your general well being, reduce stress levels, etc. This next level however is here if you want to move even further and reach your goals faster.

The ultimate plan for the 11-14 days and beyond

Try to increase intermittent fasting time to 20-22 hours, if possible. As before, no caloric drinks during this time.
Eat only 2 meals a day with both of your meals being liquid: a combination of smoothie and soup.
If you want to go even further, you can try replacing smoothies with fresh-pressed fruit juices, and replacing liquid soups with fresh-pressed vegetable juices.

It sounds simplistic, but obviously it is not that simple to achieve. The longer your fasting periods are and the stronger you stick to having only fully liquid meals, the quicker results you will get. There is no need to blame yourself if you cannot do all of this straight away. Different people need different adaptation periods, being consistent and persistent means much more than your current physical and mental condition.

What’s next

If you have managed to do everything from the previous paragraph, you are one of the rarest people on Earth. Congratulations, you are now moving to an esoteric level! If you think you need more you can go back and re-read the liquid only diet article.

If you want to go even further, here is what I think you could do:

Try consuming all your liquid meals without the fibre(pulp) – just fresh fruit and vegetable juices.
Try doing longer intermittent fasts: 36 hours, 48 hours, and even 72 hours.
Within your fasting windows, you can even try going without any water, which is said to speed up the fasting process by at least 3x times.


Transitioning to a liquid diet can take time. Although I believe 2 weeks is a decent amount of time to do it at a normal pace, people are different – for some it can take more and for some it can take less time. Any of the 3 steps can be repeated before going onto the next one. Everyone has their own goals, it is basically a free-style individual approach. Being persistent and listening to your body is the key.
