Does eating pineapples make me slimmer?

I’ve been losing weight over these few months.  To begin with, I’m not fat and I’m pretty indifferent to my weight.  I’m actually slightly irritated that people keep commenting that I’m thinner plus my clothes and even my wedding ring are now so much looser.   Actually, I haven’t done anything to shed off the kilos.  I’ve been eating the same number of meals based on the same diet.  I haven’t been exercising and instead, have been sitting in front of my computer most of the time.  So what has contributed to my weight loss?  I gave this some thoughts and I suspect, it is pineapples! 

High dose of Vitamin C
Sometime earlier in the year, I started eating pineapples on a daily basis.  I eat about three slices, which is about a quarter of a pineapple, usually after my lunch.  Except for the fact that pineapples contain lots of Vitamin C and that it is pretty acidic, I don’t know much about this fruit.  But since suspecting that it has caused my weight loss, I did some online research into the fruit.

Good source of bromelain enzyme
According to the wikipedia, pineapple is a good source of manganese and contains significant amounts of Vitamin C and Vitamin B1.  In addition, the fruit contains an enzyme called bromelain that aids digestion and helps prevent inflammation and swelling. 

Bromelain and slimming pills
I couldn’t find strong concrete scientific evidence that eating pineapples could contribute to weight loss but it looks like I’m not alone in my suspicions.  For example, I found this website that stated that pineapples can promote natural weight loss.  In addition, I found that some manufacturers who use bromelain in their slimming pills have been claiming that it can help to break down body fat and enables slimmers to lose weight effortlessly. However, this claim has not been backed up and it is said that bromelain, like any other protein in the gut, would be digested and should have no action on body weight. (source)

Vitamin B1 (Thiamine) and weight loss
But pineapples also contains Vitamin B1 (Thiamine) which is said to help metabolize carbohydrates. When I searched about this vitamin, it came up in a lot of weight loss resource websites! There appears to be some link between Vitamin B and weight loss but according to Love To Know website, Vitamin B and weight loss go hand in hand, but only when all forms of vitamin B are taken together.

Promotes better metabolism and better digestion
So does eating pinepapples really promote weight loss?  Well, I can’t say for sure since I cannot quote you any brillant information from experts.  But if you think about it, with better metabolism and better digestion that comes with eating pineapples daily, losing weight isn’t such a far-fetched idea.  However, I can only say it worked for me and I’m not discounting there could be other factors or food that needs to work in combination for the effect.

    I think you make a great point, and based on your research it sounds quite possible pineapples could assist in weight loss. At the very least, they’re delicious and healthy too :)

    Jen: It won’t yield overnight weight loss for sure. More like slimming overtime. Anyway, I agree. They’re delicious and healthy. I’m so hooked that I need my serving everyday now. And with great Vit C, why not? ;)

    • Mel says

      Hi, that all sounds good,but can i ask , are you eating one pineapple a day? it’s quite a bit big fruit:)

  2. flym says

    I love pineapples but have been advised not to overindulge in them as it is considered too “cooling”, according to TCM. Maybe I need to balance it with more “heaty” fruit like durians or mangoes.

    flym: It’s true…I’ve heard that too. Not particularly good for women during that time of the month. Plus it’s acidic so shouldn’t be eaten on an empty stomach.

  3. says

    this is interesting, i have tried so many ways and yet none of the slimming methods worked for me :( but i do take plenty of fruits (oranges) on daily basis and none of them contribute to weight loss. perhaps i am going to give this a try. thanks for sharing this info!

    prettybeautiful: Well, take it like a healthy fruit. The slimming effects are not immediate but more like over a stretch.

  4. a says

    Ooh, interesting! I experienced the same slimming effect with green tea–didn’t change my eating habits, just had about 4-5 cups a day. But maybe that’s just the effect of the tea making me eat less, since I usually lose my appetite after a cup (so bitter!).

    I think I’ll try having pineapple daily…

    I have a question, though: do you have the pineapples freshly cut, or canned?

    Hi! I eat the pineapples fresh. I think the vitamins are lost on the canned ones…

  5. says

    Great post Sesame, I am gonna include pineapples in my diet from today itself:)

    Leon: Thanks! Hope it’ll work well for you. :)

    • Cheata says

      I’ve been married for almost 2 years and we don’t have the baby yet. The doctor recommended me to reduce (even my weight and my high are normal) so I’ve tried to eat Pineapple juice from yesterday onward and hope i will get good results as others who mentioned about this fruit.

      • sesame says

        If you’re planning to have a baby, I would recommend you not to eat too much pineapples. It has a cooling effect and not good for those with weaker body constitution.

        • meena says

          My daer don’t eat pine apples if you are trying to concieve. Pine apples are not good to eat even during preganancy for about 6 months, because it can lead to miscarriages.

          i hope this is helpful to you.

          • Sesame says

            Yes, I did hear of this from my mom. Apparently in her days, a lot of women eat loads of pineapples during their early trimester when they did not want the baby.

  6. says

    One of the key health advantages of a vegetarian diet is its high fiber content.
    The Pineapple diet formula is totally a new diet system that is much different from the diet programs you’ve come across. With this system you are eventually accelerating your fat/calorie burning engine to a much faster rate and this happens within the first 24 hours of your start with this diet.

  7. says

    Funnily enough my better half came home today and by the by mentioned she came across a site where a guy had written he lost 50 pounds by eating a whole pineapple every day. Will see if she can find the link again and come back and post it. If one can actually lose a decent amount of weight I’m borrowing a friend’s pickup tomorrow and driving to the fruit & veg store! :P

    Eating one whole pineapple? But I found the side effects of eating pineapples long term is back ache.

    • Ababooo :p says

      hm? can i have the link of your source? please? why back ache? is there a connection or something? :)

      • sesame says

        There is no link that I can provide you. It’s based on my experience.

        Pineapple is considered an alkalizing food so too much of it may not be a good thing. As in everything, eat in moderation. I was eating 1/4 of it every day back then…definitely not in moderation.

  8. Namratha says

    Hi, I am thrilled to hear that pineapple play miracle in slimming down the body weight. Actually I had come across bromelain enzyme in pineapple through a magazine which stated that bromeline acts major part in reducing weight. I am going to try it this time after i browsed web of the article written by you. Thanks for putting on web.If you have any other good tips please let me know.

    Namratha: Try green tea. I wrote about the slimming effects too. Check under my category on Beautyfood.

  9. says

    I have tried lot of things to become slim but i will surely try Pineapple its something new i have heard.Hope it work for me.

    Nida: You need to be persistent. I took it daily for about 3 months before I saw results…but one thing I found is that eating too much pineapples causes backaches! So eat with moderation…

  10. shivani says

    reading abt all urs experieces s amazing. I agree too.i think v should consume only d fresh ones as canned pineapples r very sugary,turning them to high avoid that rawness of the fruit ,we can half boil them with 1 tablespoon water and few drops of honey. it can be used for yogerts and salads.

  11. SJ says

    I can’t believe I’m reading all this – for the last year I’ve been eating up to a whole pineapple a day myself. I’ve gradually lost a little over 30 pounds and have been telling people it must be the pineapple. Its the only thing I’ve done differently! I have several friends who are now starting to incorporate pineapple into their diets as a result of my weight loss. Part of the reason it works so well is simply because it really is so delicious and one just doesn’t crave other foods when eating it…. Good luck to everyone…

  12. SId says

    Could anyone please specify how much time it takes to start losiong weight. i am not greedy but just wanted to know. :D

    • sesame says

      If you take a quarter of a pineapple daily, you might see weight loss in 3 months. I use might cos there could be other factors involved so I can’t guarantee.

      However, I later found out that pineapples are too cooling and can cause backaches.

  13. Pinky says

    Hi.. My cousin wedding is after 1 month. Could u pls help me in losing 5 kg.. Wil pineapple help me in losing them in one month?? Pls help…

    • sesame says

      I can’t promise and eating too much pineapples maybe bad for your health too.

      Suggest you try eating some pineapples, drinking one cup of green tea daily and eating avocados two to three times a week. Of course, you got to watch the other stuff you eat.

  14. cara says

    Hi… I have never heard about pineapple being good for weightloss but after stumbling across this article, I would have to agree it can definitely help slim down… I started losing weight about 3 months ago and have lost nearly 12 kg in total… but through one of those weeks I ate alot of pineapple at a party when I was avoiding all the unhealthy food… it was such a delicious pineapple that I did eat a rather large amount of it… a couple days later when I weighed myself I had lost 4kg for that week… I don’t know if it was from the pineapple, or if it’s just a coincidence that the week I ate a lot of pineapple was the week I lost the most weight too… food for thought at least :-)

    • sesame says

      It’s very delicious and great for losing weight but have to eat them in moderation. I discovered my backaches were a result of eating pineapples every day.

  15. cara says

    yes, I personally believe in everything in moderation…. there’s no point doing fad diets or extreme weightloss that you’re not going to be able to maintain… slow and steady wins the race… but little tips like this are great….

  16. cara says

    Pinky, walking is also fantastic for weightloss… I walk between 6 and 12km a day on a treadmill… (1 to 2 hours)and it is great…

  17. jacklyn says

    pineapple actually burns fat as it goes down so its no surprise… green tea should help too… it helps to speed up your metabolisim

  18. Verity says

    I just stumbled across this as I googled “pineapple and weight loss” – the reason for this??? Well I’ve just come back from a 2 week holiday in Sri Lanka where whilst I ate very carefully, I did not expect to loose any weight at all (especially given the amount of curry I consumed whilst out there!).

    I have been on a diet for 3.5 months having lost 2.5 stone….but this has been gradual and as part of a plan, and whilst I tried hard to stick to it on holiday….this was far from rigidly.

    One thing I did do was eat pineapple on a daily basis, usually eating a little at all three meals – and the result……I came back from holiday having lost 8lb in 2 weeks!!!!!!

    By no means do I think it’s a miracle cure for overweight people but I’m sure that it helped my weight loss during this time when I wasn’t sticking wholeheartedly to my diet plan. The week that I’ve been back for my weight has maintained so this morning I’ve been and bought several pineapples to see what happens this week!!!!!

    I think however there is definately some truth in the fact that pineapple can be a very healthy aid to slimming xxx

  19. jani says

    don’t scare yourself from eating delicious meals, indulge yourself but include pineapple after will help digest and breakdown fats. It will definitely remove your guilt plus it makes your skin clear and supple when applied topically

  20. Muñequita says

    I definitely agree that eating a diversity of foods, including fresh fruits and vegetables, in moderation is the key to a healthy lifestyle. I’m no model and I really need to lose weight. I’ll give pineapple and green tea a try. Also, avoid read meats as much as possible, eat fish instead and include papaya in your diet. your skin and your hair will thank you. You’ll notice the difference. Thanks for sharing.

  21. says

  22. gwen says

Will definitely introduce it to my fren or relatives who finds it hard to lose weight. Wat a dilenma…one is trying to gain weight while others trying desperately to shed of d excess.

  23. mercy says

    pineapple is good for weight loss,i have been on d therapy for about two months now and i found out that am lossing weigth drastically,what i do is that i made juice out of it and initially i take at least two litre per day but when i read on d web that it can cause backpain and which i believe is true bcs i have been complaining about backpain lately and i thought it was stress but untill today when i now read about it but i now decide i should take it down to one litre per day bcs i cant stop treming down right now. Thanks.

  24. says

    I’m not sure of the weight loss benefits with pineapple, but I discovered it smooths the skin. I love to grill my pineapple with fresh veggies in chipotlett seasoning. When I cut up the pineapple, my fingers are always so soft. I assume its the acid, but I started using the center part (that I normally toss) on my face to see if it does the same. It really does soften the skin, so I decided to make my own facial exfoliate by adding sugar, and I’m amazed by the results. I now use the center to blend up and refrigerate for my own use.

  25. says

    The same thing recently happened to my mom. She noticed weight loss when in fact she want doing anything different, until she realized she had been eating pineapples everyday. After researching it she came to the same conclusion you did. I’m now trying it!

  26. Val says

    I started researching a fruit diet because of the pain to my legs after a serious accident……. (Knocked down by a car) I took coconut with the Pineapple and started straight away to be able to exercise……….. The pain in both legs went away after two days, and I felt like jumping around!! I lost the horrible hard bulk in my stomach, and watched as it started to soften, and flatten…… The actual skin was starting to shrink………. I thought wow! I lost 4 inches off my waist the first week and went down to several more over the next month, my feet and hands looked slimmer, and my skin on my face looked brighter, and tighter…………. I stopped because of the Autumn and started putting on weight, but now will definitely try this again……… I have just bought a pair of skinny white jeans and want to get in them next month……….. Pineapple and the coconut with other fruit, and veg are the must for a good balance………… The strength in my legs and knees again were amazing……….. All old people and the young should eat pineapple for healthy bones……….. Hope this has helped you!

    • sesame says

      Wow sounds amazing! I’m glad it helped eased your pain and you recovered well and quickly. That’s awesome!

  28. Cheme says

    I’ve been eating pineapple now for the past one week but i’ve not been able to see any significant changes , pls where can i get d green tea or wot do u mean by green tea? Thanks

  29. Stephnie C. I says

    I agree with you.For some time now, i placed myself on exercise, pineaple and orange intake and after some time, lost weight and was also having back ache,i thought the back ache was as a result of exercise not untill i read this article “pineaple help to reduce weight and can cause back ache” I used to take much pineaple a day and have now realized it’s the cause of my back ache. Thanks for the information, i will now reduce the quantity of pineaple i consume per day. Pls there are lots of green tea in the market, which product is the best and works fast? I use FAT BURNER SLIMMING TEA(a china product) and atimes TRUE SLIM TEA(An American product). PLEASE ARE THEY GOOD FOR MY HEALTH?

  30. Tiffany says

    I eat about 3 cups of pineapple everyday, and I’ve done this for about 4 months. I’m not trying to lose weight by doing this, I just really like fruit and pineapple in particular. Eating this much pineapple has not resulted in any type of weight loss, and I even run 5 miles per day. In fact, eating all this pineapple may actually be causing some acid reflux issues. I share this information so that others will consider the potential side effects of eating too much pineapple before someone decides to eat a ton of it in an effort to lose weight. I concur with others that the author’s line of reasoning sounds probable, but it is probably the case that the pineapple is simply taking the place of other, more fatty food, and this is what is producing weight loss. If you substituted carrots, celery, melon, or any other fruit or vegetable for pineapple, it would probably have a similar effect.

      • Raal says

        Hi Sesame,

        Thank you for your blog. I am glad pineapple helps with weight loss. Two years ago, I wanted to lose some weight so I did some exercise and tried a healthy diet that consisted of fruits and veges. For fruits, I ate lots of pineapple (about 3 slices a day), after a month or two I had trouble breathing. I couldn’t breath properly. I am in my early twenties so that was concerning and when I went to the doctor he basically told me to stop eating the pineapple, which I did and the breathing trouble went away.

  31. Angel says

    I noticed this too a while ago. I noticed that when i drink pineapple juice during lunch, I feel full very quick and find it hard to finish eating my lunch. On the other hand, when i drink orange juice i don’t seem to satisfy my thirst. Therefore, I reached the conclusion that since pineapple juice makes me feel full faster, i consume less calories. Drinking orange juice, on the other hand, makes me take in more calories because i drink more than i need to…Great Article!

    • Sesame says

      Glad you enjoy it and thanks for sharing your thoughts. I find orange juice makes me hungry quite quickly.

But just enjoyed having a bowl of pineapple at the end of the day, seems to have naturally help me lose the extra fat…fantastic! :o)

  35. Aalejandra says

    I’m 23 years old. And my doctor has told me I’m over weight for my age. My goal is to go down to 125lb. Will pineapple work..????
    Can I also use the pineapple as a drink instead of pieces…

    • clarrah says

      theres no such thing as being overweight for your age, especially as you are so young it should be due to your height. A healthy weight guided by age is only for elder persons and thats when calculated with height.

  36. Jen says

    Well, it’s was last week.. when I drop by at Waterloo Hawker Ctr, a lady share about pineapple, how it works on her, she told me.. that she was fatter than me & after she ate, daily.. she totally lose weight, she said must try but then, whenever I’m in the market, I end up buying rambutan, Langsat, pulasan & durian.. tskkkk

    • Sesame says

      Haha…everything but pineapple. ;)

      Yes, pineapples can help one lose weight but it’s also very “cooling”.

  37. wanderlust says

    Pineapples are a rich source of potassium which is a diuretic. Of course you should lose weight as you will urinate more frequently. Eating too much pineapple can eventually cause an electrolyte imbalance within the blood and cause circulatory problems. Small amounts of pineapple are fine but beware of consuming too much. Do a search for sodium/potassium imbalances caused by diuretics and then decide whether it is right for you. Please be careful. There will be a body mass lost due to water loss which could result in dehydration but l cannot see where there will be any actual fat reduction.

    • Sesame says

      Very good info you’ve shared! Yes, I wouldn’t recommend consuming too much. I think I overate and that’s why I had backache issues then.
