Banana Diet

By Mizpah Matus B.Hlth.Sc(Hons)

banana-dietThe banana diet involves a number of eating plans that use bananas as the primary food basis of the diet.

When the Morning Banana Diet was promoted on the Japanese social networking site ‘Mixi’ in March 2008 it became so popular that it resulted in a nationwide banana shortage.

The diet was created by Hitoshi Watanabe who has studied preventative medicine and his wife Sumiko who is a pharmacist.

The Morning Banana Diet Basics


The creators of the Morning Banana Diet claim that eating only bananas and drinking room temperature water for breakfast leads to weight loss regardless of what is consumed for the rest of the day.

morning-banana-dietThe diet is extremely simple and easy to follow however many Japanese have reported rapid weight loss when experimenting with this diet.

One of the reasons why the diet may work is that bananas are said to improve digestion and boost metabolism. Another possibility is that bananas are high in resistant starch, which is a type of fiber that can promote the feeling of fullness and may block the absorption of some carbohydrates.

The reason why the water has to be room temperature is not certain but many theories have been speculated on the Internet such as that it improves digestion or reduces hunger.

Dieters are also advised to eat their evening meal before 8pm and to avoid desserts after dinner. If feeling very hungry it is acceptable to have a piece of fruit.

Aside from eating bananas for breakfast and avoiding late night eating another rule of the diet is that you must go to sleep before midnight every night. The rationale behind this advice is sound as scientific studies show a relationship between sleep deprivation and obesity

At all times dieters should follow the Japanese principle of eating until only 80% full.

Dairy products and alcohol are also not allowed on this diet. In addition the only beverage that may be consumed with meals is room temperature water.

Costs and Expenses

See The Morning Banana Diet Official Website

Pros

  • Eating breakfast every day may increase metabolism and reduce the likelihood of overeating later in the day.
  • Avoiding caffeine at breakfast may lead to more stable blood glucose levels and reduced appetite.
  • Not eating after 8pm will reduce tendency for late night snacking on high calorie foods.
  • Avoiding dairy products and dessert will reduce calories by limiting fat and sugar intake.
  • Bananas are a nutritious food and high in fiber, vitamins B6 and C and potassium.
  • Discourages overeating.

Cons

  • Some dieters may not respond well to a pure carbohydrate breakfast particularly those with hypoglycemia.
  • Easy for dieters to consume excess calories if they eat whatever they like for lunch and dinner.
  • Does not encourage exercise.
  • Does not address psychological factors involved in dieting.

Less Calories Still Key

If dieters are experiencing success on this diet it is not likely to be due to any special fat burning qualities of bananas. It is much more likely that it is related to following the other rules of the diet such as eating only at specific times of the day and avoiding desserts.

This will result in a reduction of calories that will promote weight loss so long as dieters do not consume excessive calories in their other meals.

  • Marie

    Love bananas! I find ripe ones are tastier and sweeter. Unfortunately they should be avoided if you want to lose weight because they are higher in sugar. If not mistaken, greenish ones are the ones with complex carbs.
    So will try this diet but with “green” bananas. See what happens…

  • Lisa

    not even worth it guys…
    i gained 3 pounds in 3 days cause of this diet.
    I even exercised as well, this may be because “everybody’s body is different” and that maybe be the case and you can give it a try and see if your body reacts in a more positive way. but from my opinion. It’s not worth it.

    • Doug

      You may have to eat bananas for lunch too

      • sindy

        wat was your diet plan?

    • XXXXX

      I just watched a video about this diet on youtube and they said that the entire country of Japan ran out of bananas, giving that I guess it works but I’ve never tried it.

  • Craig

    I have tried various diets over the years including slimming pills however found the banana diet does actually work. I went on this diet a few years back which consisted of a banana for breakfast, banana for lunch and then a main meal for dinner. I also got into the habit of doing 30 sit ups per day. I would allow myself a SIN day on Saturday and eat/drink what I wanted. I found the first week the hardest but once you get your head round that the banana’s are purely fuel for your body, I settled into the plan easily. I lost alot of weight, had more energy and found that on my SIN day I stopped snacking or eating large meals as A) My stomach had shrunk, B) I didn’t feel a desire to snack, especially after seeing how much weight I had lost & how much healthier I was feeling.
    Just started back on the banana diet, on day 3 and already feeling positive about it (good job I like Banana’s)

  • Ila

    I’ve done just bananas at breakfast and sometimes one or two throughout the day. Didn’t even know it was a diet and increasing my water intake ex.. I think it’s helped because skipping breakfast or lunch just wasn’t cutting it. Apples also have a very cleansing affect to the body which I have been trying to do. Thinking positive even if you don’t have desired results right away really helps too.

  • Okorocharityifeoma

  • charlotte

    • steve

  • DontEatThisEatThat

    All these comments and not one says “it worked for me”. I dont see how this would work anyway. But at least a banana for breakfast is better for you then eggs/bacon.

    • serdlc64
