What is the premise of the diet?

To start out we’d like to mention that this diet is actually a “mono” diet, or a fad diet, as some call it. It’s a diet plan which consists of eating only pineapple and drinking only water or pineapple juice. It’s a restrictive diet, but has been proven to be very effective especially if you’re looking for a rapid and significant weight loss. Though it’s impossible to give your body the necessary nutrients it needs from just one product, it is an acceptable and healthy regimen if you stick to it for no more than 3-5 days.

The basics

So we already mentioned what you’ll be eating, and that’s pineapple only. (Although some versions of the diet allow for 4 ounces of tuna a day, as well). You can do that version, as well, along with 2 kg of pineapple and 2 l of water- it’s simple and easy to remember, right?

Whichever regimen you choose you need to know that both diets are fad diets and are frowned upon by many doctors.

The difference between this and other diets

The thing that differentiates this diet from other diets is the fact that it’s a mono diet, where the only product allowed is-you guessed it- pineapple. It might be more restrictive than a lot of other diets, and it does require a lot more dedication and motivation. You are allowed, or are even required to stay on other diets for more than a week, but that’s not the case with this diet. Stay on this diet for more than 5 days and you’ll start risking your health.

This diet is best used for getting rid of a few extra pounds fast, and not for maintaining weight or as a daily dietary regimen. Some people also believe that such diets as this one, which include only one or a few products, are bad for you in a way that they starve your body from a lot of healthy nutrients. Although they criticize these types of diets, and they rightfully do so, the fact remains that if you stick to the recommended period of 3 to 5 days, and don’t overdo it you will receive a lot of benefits from the diet. We’re not talking solely about rapid and dramatic weight loss, we are also talking about detoxification of the body, which is a huge benefit, don’t you agree?

Your daily regimen

As we already mentioned you have two ways to choose from:

  1. The first one offers only pineapple for each of your meals, and the quantity is limited to 2 kg a day (this means after it’s sliced up into nice and juicy pieces, not in its original form). You can either eat it or take it in the form of a juice or smoothie, just be sure not to add anything else in it. You can also drink as much water as your body needs (the recommended dose for an adult is 2l a day).
  2. The second one offers tuna along with the pineapple (well not mixed in the same meal of course). You can eat up to 4 ounces of tuna each day, which is about 200 calories, as we mentioned. The rest of the calories you’ll be getting are from your pineapples, which quantity remains the same (2 kg a day). You mustn’t forget to drink your water too, since it’s very important for digestion and hydration.

That’s it for the diet plan. Simple, right?

Now let’s check out some more facts that you might need to have in mind in order to make up your mind on whether you’d like to give this diet a try.

Nutritious value

What you’ll be getting out of your regimen are 1,000 kcal from your pineapple and around 200 kcal more if you decide to go for the tuna fish version of the diet. 2 kilograms of pineapple provide you with 2 grams of fat and 10 grams of protein. Pineapple won’t provide you with enough of the essential vitamins and minerals, but it will offer you manganese and a lot of vitamin C. If you are following the tuna fish alternative you’ll be also eating 33 grams of protein, along with 9 grams of fat. Nevertheless, the calcium, iron, zinc, potassium, vitamins A, D intake will be very low. These nutrient deficiencies however, won’t cause you any issues, since you’ll only be dieting for about 3 or 5 days, and you’ll have time to replenish your body afterwards. Just make sure that you don’t stay on the plan for more than that, since you might be facing some extreme side effects like: nutrient deficiencies, low blood pressure, an imbalance of electrolytes, as well as an irregular heartbeat.

Is this enough for a healthy diet?

What you need to have in mind is that you’ll be eating a lot less calories than your normal daily intake, and this is what will make you lose weight. The way it works is that you burn a bit more calories than you eat, leading you to a weight loss of even 5 pounds in 5 days. There can be one side effect to this low calorie consumption. When you’re not giving the body the amount of calories that it needs, your metabolism tends to slow down, and starts to limit your weight loss, so you’ll be burning a lot less then you might have expected.

Is this a healthy regimen?

There have not been any scientific research to suggest that eating nothing but pineapple is actually good for the body. People on the other hand have split opinions on this matter, some believe in the diet and its wanders, while others are warning against it, and condone it as unhealthy. Let’s try to get a picture of both sides, so that you can make up your mind on the topic.

The pros

  • It’s a fast and effective way to lose a few pounds, and lose them fast.
  • It’s a good option for all those pineapple lovers out there.
  • Pineapple is rich in fiber.
  • You’ll be getting a lot of vitamin C and manganese.
  • You’ll be eating fresh and raw food.
  • You’ll be riding your body from harmful toxins, which have been accumulating in your body, as a result of bad and unhealthy eating patterns.
  • Pineapple is known to improve digestion, which helps cleanse the colon from unwanted toxins. It also reduces swelling and bloating.
  • Your health won’t be at any risk, since the diet last for only 3 to 5 days.
  • You’ll be eating fewer calories.
  • Pineapple contains a substance called bromelain, which is a strong anti-inflammatory agent.
  • It’s a very simple and easy diet, and the ingredients are always easy to find. You just need to visit your local supermarket and get yourself a few pineapples, and that’s about it.
  • It requires no cooking, and a minimal effort goes into preparing of the pineapple.

The cons

  • It’s a monotonous, fad diet, which offers only pineapple as a food source.
  • Pineapple is known for its diuretic effects, which will lead to a loss of nutrient from your body, and you’ll have to make sure you recover from that loss, once you’re done with the diet.
  • You also need to make sure you don’t go back to your old habits as soon as you finish the diet, as that will lead you to regain your weight faster than ever.
  • This diet is a fast weight loss solution and is not good for the long run. Stay on it for only about 3 to 5 days, as the longer you eat like this, the more problems it may cause you. We are talking about problems with your kidneys, your hearth, and even with your muscles (in the form of muscle loss)
  • After 3 or 5 days on a monotonous and restricted diet your chances of overeating and binge eating increase, and a lot of self-control is required in order to avoid that.
  • You need to stay active throughout the diet, even though you might not feel like it at times, or even have the energy to do it. It’s important that you keep yourself motivated and success will soon follow.
  • Eating only pineapple, which is loaded with sugar, may cause your blood sugar to go up a bit.
  • Most of the times, when rapid weight loss is in question, the weigh that we lose is likely to be from muscles and the retained water in your body, and not so much from the stored fat. This loss of water may cause you to feel dizzy at times, so you’ll need to keep hydrated at all times.
  • If you do not hydrate yourself properly you may risk increasing the acidity in your body. So don’t forget to get in around 2l of water a day.
  • Diarrhea may occur, which is certainly an unwanted side effect, but do not worry as it is not so common, and even if it happens it will pass as soon as your body gets used to not getting any solids at all.
  • A very uncommon but serious side effect would be to see some rashes at the corners of your mouth. If this does happen immediately stop the diet.

Concerns about the regimen

  1. No other food choice

The first concern that most people have is that the food choices are so limited, that you’ll be eating nothing but pineapple. We all know that having a variety of foods helps us get enough nutrients needed for the body to function properly. This diet will starve your body from a lot of nutrients, some doctors admit. Others, however are not so concerned as we are only talking about a few days, and if you do feel like your body’s been starved from vital vitamins and minerals, than you are always welcome to buy vitamin and mineral supplements, and take one each night, before bed.

  1. Hunger

If you’re not prepared to feel hungry at times than you shouldn’t even consider going on a diet, as hunger is a big part of any diet, especially this one. This occurs as your body won’t be ready for such a large calorie restriction, as well as food choice limitation.

  1. Do doctors support it?

Now, as we already mentioned, there are some doctors that are strongly against this, and all other “mono” and fad diets, as they believe that they are not so effective, and that you’ll be more likely to get the weight you lost back, within the first few weeks. There are others who actually do support it. They believe it to be a good way to lose some extra pounds quickly and without any health complications, as the process will be so short that it won’t even be able to harm your health and your body.

Is physical exercise required?

Exercising on a regular basis is recommended for all people, of all ages. This is important in order to prevent the possible loss of muscle, as a result of a strict and calorie restricted regimen. We can all agree that the point is to lose fat, and not muscle, right? So in order to avoid that from happening try incorporating at least a light exercise along with your diet plan. If you already have an exercise regimen in place, you can just stick to it.

What if this diet is not for me?

If you feel like this diet is not suitable for you, or you feel like you won’t be able to finish such a restrictive diet, than we can maybe offer you a few pieces of advice. The premise of this and many other diets is cutting down on up to 1000 calories a day, which will lead to a more dramatic weight loss and faster results. Now if you really don’t feel like you could be able to last 5 days on such a rigorous diet, you may want to try a different approach. What you’ll need to do is still keep that calorie intake limited and try to cut 500 to 1,000 calories off your diet, but keep other foods, and not just pineapple in your diet. The result won’t be the same, but you’ll still be able to lose a pound or two per week. Remember to incorporate pineapple, as much as you can, and try to keep your other food choices limited to: lean meat, fruits and veggies, fish, poultry and so on. Do not eat foods which are rich in carbs, as your weight loss process might end before it begins. You can have your pineapple as a dessert, as a fruit salad, as a snack, or even as breakfast. Remember that you can also take it in form of a shake or a smoothie, and we all know how good a pineapple-berries smoothie tastes, right? You’re guaranteed to burn calories, and fat, simply because you’ll be limiting your calorie intake, and you’ll be riding yourself from simple carbs. Do not be discouraged, as the weight loss won’t be the same as it would have been if you were to solely eat pineapples.

Here are some sample meals that you might eat, that will help you lose weight faster:


  • Oatmeal with chopped up pineapple
  • 2 scrambled eggs with a wheat grain piece of bread
  • Cheddar-mushroom omelet
  • A mixed fruit salad with pineapple, berries and kiwi
  • A boiled egg with a piece of whole grain toast, spread with butter, and one sliced cucumber
  • Cereal with a cup of milk and a cup of unsweetened coffee on the side


  • Tuna salad with a piece of whole wheat bread
  • Lettuce wrap with tuna, tomatoes, corn and grated cheese
  • BBQ chicken with a green salad
  • Grilled mushrooms, asparagus and zucchini with a green salad
  • Grilled salmon with brown rice and corn
  • Greek salad with grilled fish and a piece of whole wheat toast


  • Whole wheat pasta with a tomato sauce and parmesan
  • Grilled chicken sandwich
  • Roasted chicken breast with spinach and rice
  • Tuna salad
  • Roasted asparagus with a hummus dip
  • Stuffed sweet potato


  • A handful of almonds
  • A cup of mixed fruits
  • Pineapple smoothie
  • Pineapple juice
  • Lemonade
  • A cup or coffee or tea

There are a lot of important factors that need to be taken into consideration before you start this diet. You need to get physically and mentally prepared for such a rigorous and restrictive diet. And most importantly you need to be prepared for what’s to come, not just for the dieting process. As much as the 3-5 days dieting period is important, so is the part after. You will need to watch what you’re eating, so as not to immediately go back to the weight you were before, or even put on some extra weight. You need to respect and follow the simple rules of the diet, in order to achieve maximum results, and you’ll also need to respect the time frame, since staying on this diet for more than 5 days is not recommended.
