How To Do A Banana Diet Plan For Detox, Weight Loss And Health

Banana diet plan, or a banana island, as it is also known, is an easy and sweet way to achieve detox, weight loss, boost your health and , help you enjoy simplicity and aids your body’s healing.

I’ve done several banana diets (or banana islands) myself and have also coached other people through their own banana cleanse. Today, I am going to talk about all the ins and outs you need to know about this process and how you can do it yourself.

Here is a video about it:

The benefits of bananas

Bananas are one of the world’s healthiest foods. One of the greatest things about bananas is that they are available year round anywhere you are and they are also cost effective, if you look at the calories that they provide.

Bananas are rich in B vitamins and magnesium and they contain zero cholesterol. When ripe they are also packed full of simple sugars and a great way to give your body an energy boost.

Bananas are high in potassium – a mineral that allows you to maintain healthy blood pressure and heart function. A medium banana contains 400+mg of potassium.

Studies (1) show that a diet rich in potassium helps you prevent high blood pressure and protects against atherosclerosis (heart disease).


Bananas also improve your digestion due to them being high in fiber, which helps regulate the speed of digestion and allows for regular bowl movements.

Bananas contain fructooligosaccharides (FOS) – a unique type of carbohydrate that helps maintain “friendly” gut bacteria in your lower intestine.

There was a study done (2) where participants ate 2 bananas per day form 2 months and this led to a significant increase of Bifidobacteria.

On the high fruit raw food plan that we promote, people can eat between 10-30 bananas per day – so no problem with Bifidobacteria there!

What is a banana diet?

The banana plan is very much what it sounds like – you eat bananas for a period of time.

I’ve personally done the banana diet myself several times, lasting from 3-12 days and I often get questions from people that ask: “Should I just drink bananas? Can I add milk to my smoothies? Can I drink coffee? Can I add sugar to my smoothies?”

The point of a banana island is that all you eat is bananas.

In saying that, I would now definitely recommend adding greens (like lettuce, celery, micro greens) and even coconut water to your banana smoothies, at least once a day.

In this way, you will be getting more minerals and other nutrients.

Other than that, you don’t eat any other foods or substances. No coffee, sugar, spices, or any other foods other than just bananas, greens and coconut water. That’s it — simple and sweet.

How long should a banana diet last?   

If you wanted to give your system a quick re-boot, you can do a weekend banana cleanse, starting on Friday and finishing on Sunday evening.

One thing that I have to point out is that you shouldn’t do banana islands all the time. In fact, you need to receive a diversity of nutrients in your diet.

So 1-2 times per year, for example in the spring or in the autumn can be an idea, if you wanted to do the banana island.

Also, be sure to rest enough during your cleanse as your body will be going through a deeper detox and restoration.

Your bananas need to be ripe, which means soft and spotty, as unripe bananas will upset your digestion.

Does the banana diet work?

Yes, however only if you continue with the healthy, whole-food plant based diet that includes plenty of raw foods following the banana cleanse.

So go on a banana diet to reset your body so you can then switch to a healthy meal plan, which we talk about in detail in Thrive On Raw: Easy And Practical Guide To Starting And Succeeding On A Raw Food Lifestyle.  

Here are some benefits that you can get from going on a banana cleanse:

  • helps you detox
  • can speed up healing and recovery
  • can result in natural weight loss
  • increases vitality, energy levels and mind clarity
  • can boost your fitness level and sports performance
  • one of the best ways to switch to a whole food, raw or high raw food diet

Banana diet for detox and weight loss

“Don’t eat bananas because they will make you fat!” “Bananas are loaded with sugar!” These are two popular statements that you can often hear. However, they are not true.

Both Paul and I have been following a fruit-based raw food plan since 2009 and bananas are our staples.

We’ve had a healthy level of weight all these years and know plenty of raw foodists who are in great shape and eating bananas daily.

Bananas can only promote weight gain if you over eat on calories. The same is true for any other food – and not just bananas.

A banana island is a great way to help your body shift excess weight and help your body detox. The main reason for this is that you won’t be consuming the kinds of foods that lead to weight gain, such as processed foods (even if they are vegan!).


A banana island is also a tool to help you transition to a much healthier diet, such as a fruit-based raw or high raw plan.

If you want to create a beautiful body and stay lean long term, the secret is a whole-food, plant-based diet, including other lifestyle factors, such as exercise, sleep, stress management, etc.

My banana diet results

I’ve now done several banana cleanses and I enjoyed them all.

Here are some of the benefits that I personally experienced:

  • Felt AMAZING throughout the whole “journey”
  • Experienced very sharp clarity of mind, which allowed me to restructure tasks and activities in my life and set goals for new projects
  • Felt balanced, in fact, discovered the kind of balance that I have never experienced before
  • Been even more positive than ever
  • My skin got even shiner and silkier
  • Ran 22km up and down a very steep mountain called Doi Suthep in Chaing Mai, Thailand during my 7-day banana island. Recovered in double quick time, did not have any leg soreness. Also set a new PB for my 5km running!
  • Energy, energy and more energy! Did lots of fitness – cross-fit workouts, cycling, weight-training, dancing – didn’t want to stop!
  • Body felt more flexible than ever

Here is a video about my 12-day banana only detox diet and what happened to me (nearly 4 million views!):

Banana diet plan

The great thing about a banana island is that it doesn’t require you to restrict your calories. So you won’t feel hungry!

All you need to do is replace your regular amount of calories with bananas. A typical medium banana contains about 100 calories.

So if you are a female eating 2,000 calories per day – that’s about 20 bananas. If you are a male eating 3,000 calories per day, that’s about 30 bananas.

Divide your regular daily calories by 3 and you will get the amount you need to eat for breakfast, lunch and dinner.

For example 2,000 divided by 3 = approximately 660 calories, or about 6-7 bananas per meal.

    Count me in, great idea, I need to detox! Love the plan, will do mine for about 5 days initially. Funny ending on the video, keep ’em coming!

  2. Dolores Gaona says:

    I will definitely try it for a day. Then will decide if I want to go for a longer period of time. Thanks!

  3. Jakub Misiek says:

    I always wanted to do a banana island… and I have been buying bananas by the box this winter, but I seem to get bored of just bananas. I always use them for smoothies with another fruit. I will sometimes mono meal, but usually will have them with either dates or apples. I still would love to do a banana island! Maybe I should try just 3 days so that I know I will be able to do it. Thanks for the continued support and inspiration Rawsome Healthy!

    Hi Yulia! I love how you guys call yourselves fruity mama and papa!! I have followed your videos quite a bit and just love everything you are doing. I also was so happy to see you and Paul and your baby and got so much inspiration to help my children eat vegan..they are really into it and I feel like I have a whole team now….maybe Paul could make a video for my husband to encourage him to join us! Not an easy situation but there may be hope! Anyway, this video comes just at the right moment because I have been curious about banana island and just could not figure out how I would do it exactly. I put on 20 lbs (and now weigh 145) about a year ago when I went high carb low fat and I am honestly struggling to get that weight off! I am eating super clean and simple vegan raw till 4 style and loving it…but really tired of the fat that has come with it. Help!

      Are you exercising? Eating more than your body needs? How’s your sleep? Any other factors that you can identify that can contribute towards your extra weight?

      • kat says:

        I have the same problem. If I work out my amount of calories needed, then subtract 400-500 for weight loss, I end up with only 1000 calories for the day. thats 10 bananas a day. :,( thats not going to keep me full

    I’m going to try this…a weekend is a good time as you suggested. I’m currently trying to heal from Rheumatoid Arthritis. Luckily I have a milder case of RA but it’s still annoying and controlling my life. I’m trying my best to let go of old habits and have pretty much made the switch to a vegan diet and will then move on to transitioning to a majority raw diet. This could be the push to get me over the hump. Thanks for the great vid!

  6. Sheila says:

    Could you please help me? Am I the only one who hates store bananas? They are so disgusting. I eat them spotted. I buy them by the case and throw many away. I don’t freeze them because I don’t want to eat frozen foods. I typically eat them plain. I tried smoothies. I don’t like the texture. All gooey. I have to force myself to eat them and try not to throw up. I pray everyday God will help me like bananas because they are cheap, healthy, and don’t require any prep time or clean up.

    Does anyone else think they are gross? Any tips for eating them? I spent all this money on a blender, but my banana smoothies taste awful. Even just a sweet banana and water alone taste bitter. When I blend bananas they taste bitter to me! I tried dates, coconut water, raspberries in my smoothie. Still can’t hide that awful banana taste and texture

    Please help me love bananas. I used to eat 12 a day, hating them still but loving the results. Now I might only eat 2 or 3 a day. I would love to do this cleanse if only I could enjoy my food

    • Rawsomehealthy says:

      No problem, you can do it on any other fruit you like, for as longs as you can get your calories from it. Mangoes, grapes, persimmons – these are just some examples.

      It’s ok to have times when you don’t want to eat a specific fruit, and then have times when all you want to do it keep eating it. Trust your body and don’t force yourself. Hope this helps!

    I love bananas, but they give me a headache! I have lupus and histamine issues and just started on 80-10-10. Any advice? Thanks.

    • Rawsomehealthy says:

      Please see my reply above re: bananas. All the best with this lifestyle, things improve the more you do it!

  8. sasa says:

    Hi. I had done this kind of diet with grapes before a long time ago. The result was really amazing. I lost kilos and my skin was more shiny than ever. My question is the diet that you have to do after this one in order to avoid stomach problems.
    I am waiting for your answer

    • Rawsomehealthy says:

      Great question! You can use the banana island as a mean to transition to an all raw or high raw, plant-based plan.

    Great article! Im thinking of trying banana island for 3 days to see how my body reacts. But I have a question, I normally workout (cardio and some strenght training) once or twice a day, during a 3 day detox do you think I should workout as normal or cut it down?

    Thankful for an answer!
