Pasta for weight loss

This paper hit T'internet recently and has been cited all over the place:

Effect of pasta in the context of low-glycaemic index dietary patterns on body weight and markers of adiposity: a systematic review and meta-analysis of randomised controlled trials in adults

Obviously the sole claim to fame for the paper is the conflict of interest statement. I've greyed it out so no-one is tempted to read it in full, the flavour is all you need:

Quite what is wrong with CRB, SBM and LAL that they have no competing interest to declare is not specified.

So. This a BMJ publication. The critical aspect to me is the publication date.


Was it April the first?


Well. It should have been, except April the first this year was Easter Sunday. Not even at BMJ do they hit the "publish" button on a Sunday morning. Easter Monday appears fair game and someone at BMJ appears to have been at work to hit said publish button on April the 2nd.

Ah, the twists of fate produced by the lunacy of the movement of Easter through the calendar.

I think someone at the BMJ may have a sense of humour. Reading the conflict of interest statement, I wonder if the authors do too and whether there was some collusion in the choice of publication date.

Otherwise it's not funny.

We must discover if this was a joke or not. I hope someone will post The Truth.

If not a joke – holy shit!

No other articles came out on that day... could be a joke.
Actually, is BMJopen the same as BMJ?

Here's another one that looks kinda interesting:

I can't recall reading a meta study that helped me understand anything..

Every paper has to stand on it's own -- many don't - a few do.

Many meta studies cherry pick based on some unwieldily inclusion criteria to insure they get the results they were paid to get...

Sadly - I don't think this was meant to be a joke... yet it is.

' International Carbohydrate Quality Consortium (ICQC)' etc.


I was right to feel paranoid all along. These people have THE CARBOHYDRATE CODE.

Shhhhhhh.

altavista,

Wow! Their data are probably solid. Their logic is garbage, of course. Their study design is utterly bent. Now, I have been largely avoiding very sweet foods for about 15 years. To me a tomato tastes of sugar, fried leeks have a clear sugar taste, red peppers taste very sweet. So they have a normal phenomenon but choose use it to support a low fat dogma when they could equally have supported a low sugar dogma. Of course they could have looked at both and learned something about sensory perception. But what's the point of that???

They knew we need "protection against the dietary influence of fat" before they even started, so you need conclusory remarks to get there.

True Larry Ellison style: "the answer is Oracle, now what was the question?" lol

I noticed something like this after I'd low-carbed for awhile. Sometimes I boil / steam carrot, brussels sprouts, tomato, and broccoli together. The liquor is distinctly sweet. Not "candy" sweet, but sweet. Even without the carrot the sweetness is there.

That paper us funny. The first thing it reminded me off was my 3 year old daughter climbing up on the kitchen table and sticking her fingers in the butter dish, stuffing butter in her mouth as fast as she could go.

Pass, nothing at all like this image from this article?
