You know the tip about eating off a smaller plate to lose weight...?

Haji 2003

126 views

Turns out the person who came up with that one and a number of others was not always telling the truth:

https://www.vox.com/science-and-health/2018/9/19/17879102/brian-wansink-cornell-food-brand-lab-retractions-jama
 

And the reason for his misdemeanour:

Quote

To be more competitive for grants, scientists have to publish their research in respected scientific journals. For their work to be accepted by these journals, they need positive (i.e., statistically significant) results.

That puts pressure on labs like Wansink’s to do what’s known as p-hacking. The “p” stands for p-values, a measure of statistical significance. Typically, researchers hope their results yield a p-value of less than .05 — the cutoff beyond which they can call their results significant.

 

 

And then there is the wider issue about how researchers are motivated and rewarded:

Quote

 

In 2016, Vox sent out a survey to more than 200 scientists asking, “If you could change one thing about how science works today, what would it be and why?” One of the clear themes in the responses: The institutions of science need to get better at rewarding failure instead of prizing publication above all else.

One young scientist told us, “I feel torn between asking questions that I know will lead to statistical significance and asking questions that matter.”

Sure that one seems to have a lot of 'face validity'.

The problem seems to have been that for some of his studies Wansink played around with the data to make the results seem more significant than they really were.

And the problem with that is that other studies that were done completely correctly will have a shadow of suspicion over them, unless the raw data is still around.

Anecdote here-

ive had a lot stomach problems and have quite the sensitive stomach

smaller plates and eating the plate longer or taking my time and eating as I’m hungry have helped me a lot. Can’t say much for long term weight loss, I lost the initial like 10lbs over a period which may be water weight or whatever. Eating less helps with cravings and feeling full longer becuase you force your body to work on that little bit. Which may be all you need

but that depends on your body weight or and lifestyle. May not work for others 

like I don’t lose weight no matter how much I fast or don’t eat at all. I don’t lose anything t-t lol

well I really only eat junk food XD

so eating healthy is the key

on the other hand if I’m reeeaaallly hungry and can’t eat or have nothing to eat I just watch some mukbangs, or daydream about food all day...until they close...and it’s too late to eat lol

      He was Islam's backbone
      His wisdom and bravery was widely known
      None of them could beat his intelligence
      And for that they called him the peak of eloquence
      It was his powerful words that continued to guide mankind
      To be fair, honest, loving and kind
      He stood by his cousin's side like a shield 
      Everytime they had a mission
      And had to face opposition 
      It was he who gained them victory
      In the greatest battles of history
      The first man to submit his will to God
      The first man to pray behind the Chosen One
      The only being to be born in God's house
      The only being who was fit for leadership
      Slayed the strongest enemies with one strike of his sword
      It was never done in arrogance, but for the sake of the Lord
      Never wanted to take over the authority
      Even though it was meant for him and his hereditary 
      For he was neither greedy nor selfish 
      He didn't want the name of Islam to perish
      He continued saving God and His Messenger's message
      Despite being surrounded by immense pain and wreckage 
      He never stopped preaching honesty
      Of the Holy Book and the Holy Progeny
      He was indeed the backbone of Islam
      The true light to civilization of Islam
      peace be upon you, commander of the faithful, Imam Ali (عليه السلام)

      Some days feel low and some days feel high
      some days I find joy and some days I just cry
      its a mixture of heightened emotions that I can’t even describe
      some days feel tough and some days feel like a breeze
      some days I find comfort and some days I can’t find ease
      its a mixture of heightened emotions I can’t even describe
       
      lost and trapped in this loophole
      don’t know when I'll get it under control

      W.I.M stands for 'woe is me".
      We get new threads on Shiachat started by new posters who typically relate some domestic issue where a woman has been badly treated by either the father or the husband and occasionally some other male.
      The story, since these posts are typically reasonably long, has a fair amount of detail and explanation and has clearly been written by someone with a reasonably good command of the English language. We are not talking about someone who has secretly grabbed access to the village computer in some remote part of a developing country.
      Not unreasonably the post elicits uncritical sympathy from most Shiachatters. After all, if you saw Bambi's mother wounded in the forest would you not do all you could to support her and criticise the hunter in the process? 
      Given the patriarchal nature of Muslim societies, the collateral damage is, of course, the implicit criticism of such societies, their institutions, cultural norms and so on. So for example, if someone has been taken advantage of through the use of mutah, then invariably there will be concerns directed at the practice and the people who engage in it.
      And to my mind, that is the objective of these threads. 
      The following are the reasons why I usually have grave reservations about their authenticity:
      The person writing them is articulate and educated. They know how to construct a narrative that works. This is not an easy skill to acquire. Their spelling and sentence construction are always good. This matters because such education does not exist in a vacuum. Anyone who is educated to this level has a knowledge of their environment and you'd expect the support systems where they could get help (if that is what they wanted). The poster typically writes about a situation where they were taken advantage of, sometimes as a result of their lack of knowledge e.g. the terms of mutah. Now that situation would be entirely reasonable if the person was writing about a situation pre-internet. However, if they are writing about any event within the last 5-10 years the question which arises is that any google search of various Islamic issues throws up results that include Shiachat discussions. We are therefore being led to believe that the first time this person heard of Shiachat is when the situation imploded and not beforehand. Allied to this point the question why someone would turn to anonymous, generally unqualified strangers for help when it would make more sense to approach organisations and institutions they were familiar with and which would both offer an independent and trustworthy point of view. If someone can find shiachat on google they can find such resources. There are often references to the poster's fragile state of mind, which in my opinion is simply there to head off any uncritical assessment. In developed countries the first person anyone would go to in a fragile state of mind would be there local G.P. (doctor) and they would refer the person to appropriate sources of help. Such stories are always about 'relationships'. The topic is sexy and everyone has an unqualified opinion. We don't get similar posts about any other aspect of human activity. We don't get anonymous new posters writing in detail about the challenges they face in terms of choosing between medicine or engineering, for example.  The question then is what motivates such posters?
      In my opinion, it is to attack Islamic and Shia institutions and practices, it is to sow discord amongst board members and certainly it is to provide ammunition for those board members who have an anti-Islamic agenda and who can use these stories as the basis for attacking people with a more orthodox mindset.
      You may well ask what would qualify such threads as being genuine. 
      I'd expect a genuine poster to leave out the 'gory' details. After all, that is for the benefit of feeding the bun fight that is supposed to follow. I would expect a genuine person to explain in very general terms the situation that they are facing and then to ask posters if they are familiar with any sources of support in a particular country or region (this assume that they can't find such resources themselves). At a push, I would say that a new poster could say that they wanted to speak to someone qualified and whether board members or moderators could point them in the right direction.

      Salam everyone, 
      Recently, I had the privilege to attend a workshop on the above topic and I took some notes.The actual workshop was much more thorough and extensive and full of valuable information. I am posting just a few points here which in my opinion are the most commonly made errors and other things we tend to overlook as falliable humans, with the intention that we can all InshaAllah improve our Taharrat and Salat. (These are as per rulings of Ayatullah Sistani(may Allahسُبْحَانَهُ وَ تَعَالَى prolong his life) May Allah shower his bounties upon the brother who conducted such a useful workshop.
      Do not stand [for prayer] within it - ever. A mosque founded on righteousness from the first day is more worthy for you to stand in. Within it are men who love to purify themselves; and Allah loves those who purify themselves. -Quran 9:108
      GHUSL
      1. While doing ghusl people generally wash the body first and then continue with the Niyyah of ghusl. If they are doing this then what needs to be done is, make a demarcation between regular washing and ghusl. So one washes himself/herself as in a regular shower -->  steps out of the shower ---> makes Niyyah for ghusl --> steps back in. 
      OR
      regular washing --> turn tap/shower off --> do ghusl niyyah --> turn tap on.
      2. Head should always be washed first(ghusl e tartibi) It's mustahab to wash the right side first. The rest of the body can be washed in any direction, even from feet up.
      3. Tattoes; If the ink is on the skin and forms a barrier to the water reaching the skin, it should be removed. If the ink is under the skin, nothing needs to be done.
      4. Wajib ghusl often compensates for Wudhu, but if one passes wind during or after ghusl then for the purpose of praying namaz, either the person does a separate wudhu afterwards or starts ghusl again ( step out --> do niyyah --> step in shower again)  
      5.Body parts often missed in ghusl - under the chin, neck, armpits, under the feet. 
      WUDDHU
       1. One wuddhu for all salats is sufficient even if one did specific niyyah for one salat. So you can do wuddhu in the afternoon with niyyah for Zuhr for example, and pray asar, maghrib and isha with the same wuddhu ( as long as nothing happens which invalidates the wuddhu) things which invalidate wuddhu:  https://www.sistani.org/english/book/48/2159/
      2. Wuddhu consists of:
      - two washes (face & arms)
      - two wipes (head & feet)
      Washing face
      While washing the face start from the forehead, go from the hairline to the chin vertically.One has to wash from top to bottom. Horizontally, the span of one spread hand (from thumb to little finger should be covered) 
      one wash is good, second wash is good, third wash makes wuddhu BAATIL. 
      False eyelashes need to to removed.  
      Washing Arms 
      Start a little above the elbows just to be on the safe side. Go right upto the fingertips. (People sometimes tend to miss washing the hands or fingertips since they might already be wet, but they must be covered while washing the arms) 
      As for face one wash is good, second is good, but third wash makes wuddhu BAATIL. Once you have poured the water from the elbow to the finger tips you can wipe/rub with your hand all you want to make the water reach the between the fingers or all round the arms, but if you pour water again and again it will count as second and third washes and makes wuddhu invalid.
      INGLOT or other nail polishes which claim to be water permeable, it's better to remove them. 
      Wiping head and feet
      The breadth of wiping both the head and feet is three joined fingers
      The areas to be wiped should be dry
      While wiping the head ,the moisture doesn't have to reach the skin. Wiping can be done on the hair too UNLESS a.there is some oil based gel etc or some other barrier or b.hair are long that they fall on the face then one should part the hair and do the wiping on the scalp. Recommended is that the head should be wiped from back to front. 
      While wiping the feet and head, it's the hand that should be moving on the head and feet. The head should be stationary and feet shouldn't be moving(so ideally no wobbling while trying to wipe one foot then another) nothing wrong if they move a little but repeating again, its the hand that should be moved over the head. So if one place his palm over the head for wiping and moves his head instead of his hand , his wuddhu is BAATIL. 
      The moisture for wiping should come from the wudhu itself, means no wetting of hands again after washing arms, for wiping. If the weather is hot and one's hands become dry quickly after washing one can obtain moisture from his beard for wiping.
      The sequence of Wuddhu must be followed; washing of face --> washing of right arm --> washing of left arm --> wiping of head --> wiping of feet 
      The wuddhu must be uninterrupted.Maintain continuity in Wuddhu, means you cannot wash your face, watch 5 minutes of football and then start washing your right arm. lolz
      SALAT
      While saying takbiratul ehram, body must be stationary.
      Raising of hands while saying takbir is mustahab, not wajib.
      A person should pronounce Takbiratul ehram clearly and with the correct pronunciation. For eg say Allahu Akbar and not Allah wakbar
      In Wajib namaz,If one chooses to recite Surah Quraish after Fatiha then Surah Fil has to recited with Surah Quraish. Similarly, Surah Nashra  and Surah Dhuha have to recited together.
      The is no islamic basis of turning the rings towards palm in Qunoot
      Tashahhud: Ashhadu alla illaha illal lah, wahdahu la shareeka lah, wa ashhadu anna Mohamman abduhu wa rasuluh
      While saying tasleem either one says all three, or one can say just the last one(bare minimum). But he can't say just the first one (Assalmu Alaika Ayyuhan Nabiyu wa Rahmatul Lahi wa Barakatuh) or just the second one( Assalamu Alaina wa Ala Ibadil Lahis Saliheen) or just the first and second so either its all three or just the last one (Assalamu Alaikum wa Rahmatul Lahi wa Barakatuh)
      SOME GENERAL ADVICE:
      1. It is very important that a person learns correct recitation and pronunciation of the surahs in Salat. there aren't many, so we should invest some time listening to the recitation on you tube etc in an attempt to master the recitation.
      2. There are several duas that can be recited in while performing wudhu. They are available on duas.org.  http://www.duas.org/wadhu.htm   What one can do is, print them out, put them in a plastic cover and put them on the wall besides his place of wuddhu.
      3. Something that I have implemented in my life over the past few couple of years. Whenever you go to the bathroom or restroom,or before going to bed make it a habit to do wuddhu. Takes only a minute or so, but the sawab and benefits you get is enormous. for eg.He who renews his ablution without [the need to do so to purify] an impurity, Allah renews his repentance without him [needing to] asking for forgiveness.’ Imam al-Sadiq (AS) [Wasael al-Shi`aah , v. 1, p. 264, no.7

      In a previous blog post I identified threads that I considered problematic, since they had the (un)intended effect of causing friction with the Shiachat community.
      I think that friction emanates from people on both sides of the debate taking an emotional approach to the issues. While I cannot legislate for those people who deliberately want to diminish the faith, those people who want to take a pro-Islamic constructive approach could consider the following suggestions.
      In order to address such posts you do not need to question elements of the story, if you do it just draws attention away from the OP to you (which is a possible intended purpose of such posts). So take the narrative at face value. You are welcome to make factual observations and no moderator can take down your post if you do this. If the OP's thread makes reference to unIslamic behaviour, you can point this out (but stay factual, remember a possible goal of such threads is to present Islam as unsympathetic). You are also welcome to make observations of errors in the OPs understanding of Islamic concepts and those of their oppressors. Your task here is to move criticisms away from Islamic teachings and institutions and onto individuals and their misunderstandings If there are practical and legal solutions to the problem point these out. Often the OP will have ignored these in order to elicit an emotional response and it is worth focusing on these practical solutions. You can thereby present yourself as being helpful and constructive, while at the same time undermining the OPs (possible) agenda .

      Thought I was never going to change
      Now thinking about it just feels strange
      'Cause I never used to see it coming
      I saw myself changing and chose to ignore it
      It was for the good but mostly for the bad
      Even after I realised, I was neither happy nor sad
      I became nicer but less faithful 
      Maybe I should've been more careful
      The things I told myself I was never going to do 
      Now I do them like it's not so bad
      I know I didn't completely change to the worst 
      But I know my level in faith decreased
      Maybe I just wanted to fit in 
      And experience it all
      Maybe I felt like I was restricting myself too much 
      I do not know when I'll climb back 
      When I'll return back to my original phase
      Where I was so dedicated to my faith.
      No matter what obstacle would try and deceive me.
      Never thought I was going to change
      Now thinking about it just feels strange
      'Cause I never used to see it coming
      I saw myself changing and chose to ignore it.

      Such hard things in life that you can't even cope 
      But with God by your side, you can't just lose hope
      All that pain keeping you up tonight 
      You just gotta keep reminding yourself that it's alright
      For that silent growing pain is only temporary.
      Strengthening our faith and pushing away the guilt that wasn't even necessary.
