Talk:Very low calorie diet

Capitalization[edit]

I think that the title should be Very low calorie diet because it is not a proper noun. See WP:CAPS. 75.26.11.133 02:00, 16 March 2007 (UTC)

Citation really needed[edit]

The claim: "The body will break down fat, but it will also break down muscle and other lean body tissue which can be very dangerous." REALLY needs a citation, as this is one of those vague claims that has a tendency to perpetuate itself by being stated over and over again without any proof. —Preceding unsigned comment added by Jcordone (talkcontribs) 16:43, 14 January 2008 (UTC)

I agree 100%. For all the claims of slowing down one's metabolism or the body breaking down muscle, I am having a really hard time finding evidence to support these claims. —Preceding unsigned comment added by 69.1.116.33 (talk) 00:16, 12 February 2008 (UTC)

Several problems with the article[edit]

  • First of all, juice certainly isn't a low-calorie drink. I have removed that part from the introduction.
  • Secondly, do VLCD diets really require medical supervision? In Sweden, they are sold for use during two weeks without any supervision needed.
  • Thirdly, a producer of VLCD products claims the risk of gallbladder disease (specificially stones) is removed when the VLCD diet contains at least 7 grams of fat per day, which apparently is the requirement since several years (at least in Sweden). The current source for gallbladder issues is from 1992. Does anybody know of a newer source?
  • Fourthly, the part about setting up a bigger health risk once the diet is over seems strange. VLCD diets are intended to be used only for a certain time period. Also, the source is a blog article, not about any method in particular but rather dieting in general. It mentions excercise as the best weight loss method in conjunction with healthy eating. All VLCD products I have seen are intended to be used for a period to lose weight, in conjunction with excercise and a gradual taper to regular healthy food. If used as these products are intended, the blog article doesn't seem to really apply. It just seems very POV, very vague and very discouraging for people who use VLCD diets.
  • Fifthly, aren't VLCDs supposed to be nutritionally complete (see intro text)? If so, why does the article claim that the lack of essential nutrients will deteriorate hair and nails? Also, the talk about serotonin levels seems related to thinking VLCDs contain too little amino acids to produce enough serotonin, which also contradicts the intro text. Of course, osteoporosis and electrolyte imbalances are unsourced as well.
  • Sixth, low calorie diets are low in protein. Protein is responsible for the building and maintaining muscle. Muscle requires more calories than any other tissue in the body and is therfore crucial for a fast metabolism. Loss of muscle is a real post diet danger as the ability to burn calories relative to a persons normal daily calorie consumption is drastically reduced, thus sabortaging the dieter as they pile on more weight faster than they lost it. — Preceding unsigned comment added by 86.150.176.80 (talk) 11:31, 9 April 2012 (UTC)

Any suggestions on what to do about the above points?

The fact that they are sold in Sweden without the need for medical supervision being stipulated, might be a reason to amend that information for the Swedish Wikipedia. However, the U.S. codex (as can be read at http://www.medterms.com/script/main/art.asp?articlekey=76935 among other places) specifically defines a VLCD as "a doctor-supervised weight loss plan".--Roger Pilgham (talk) 13:37, 13 February 2009 (UTC)
Hm - for some reason I missed your reply despite having watched this page. Anyway. I don't think it is right to use the US as the ruler to which everything should be measured, and then use that measure to claim that others is deviating from whatever the standard is according to the measurement. That would be to unwittingly introduce a North American bias, when in fact Wikipedia is international (after all English is spoken in countries other than the US). I used Sweden as an example since I happen to live here, but as you referred to a dictionary definition written in the US, I decided to Google for some more information and found this:
  • "VLCD products that are prescribed for selected patients under medical supervision and which are only available in hospitals or comparable situations. This applies to Germany." [1]
  • In France, VLCDs are prescription only.
  • In Belgium, VLCDs are OTC in pharmacies.
  • In Denmark, Finland, Ireland, Italy, The Netherlands, Portugal, Sweden, The United Kingdom, and Norway, VLCDs are freely available. Of these, only Denmark, Norway and Portugal have implemented the non-statutory standard Codex alimentarius STAN 203-1995, which references STAN 180-1991, which in its turn contains the labeling requirement "A prominent statement "USE UNDER MEDICAL SUPERVISION" shall appear on the label in bold letters in an area separated from other written, printed, or graphic information."
I did not search for the "US codex", but could not find it at the link you suggested, although I have my suspicions that it is indeed the aforementioned Codex alimentarius standard that you intended me to find.
This means that six EU countries use national or other regional standards, which do not neccesarily contain the particular labeling requirement that your article article states. The COMA standard of the UK seems to call for (but not neccesarily require; "should" is used instead of "must") doctor's consultation prior to the person embarking on a VLCD, as seem to do Norway's and Denmark's regulations (the literal translation here would be "ought" to consult a doctor). In Finland one may use a VLCD for up to three weeks without consulting a doctor, however it may be used for longer periods under supervision. however, as I can't read e.g. French I am not sure exactly what the standards in Belgium, Italy and Portugal are. Also interesting is that several of the larger VLCD programs I've found seem to imply that a child (at least those 16 years of age) can use a VLCD in some of these countries under medical supervision, even though the Wikipedia article states one must never put a child on a VLCD. Since these progrms are rather well-known/established (i.e., Cambridge program in UK, Nutrilett in Nordic countries), it would seem to me as unlikely, although possible, that they have escaped governmental oversight and regulation - as this is mandated via compulsory registration of the programs by the applicable policies in at least UK, Norway, Sweden, Denmark and Finland.
As a result, I think the enwp page should be updated to say that a) VLCDs are to be used after consulting a doctor in many countries, and that in some countries medical supervision while on the diet is suggested; however some countries allow the unsupervised use of VLCDs for a limited amount of time (usually up to three weeks), and b) that in many countries VLCDs are contraindicated to be used by persons under the age of 18, but that in some cases it may be helpful for adolescents to use a VLCD if they suffer e.g. from very severe obesity [2] or diabetes [3], when under medical supervision.
Unfortunately, I don't have the opportunity right now to actually go dig up these sources and read them fully; this is why I put this on the talk page so that someone who has access to proper medical sources or has the opportunity and willingness to go look them up can go do that and insert properly sourced additions to the article. Or, I may come back and do this in some months' time when I have the time/energy to do that myself. Just have to find that univerity library card which I have somewhere... Also, the remaining items on my list are still unaddressed - if anyone does go look into VLCD sources, perhaps they can address those issues as well. WnC? 21:24, 17 April 2009 (UTC)

In Australia, VLCDs can be purchased off the shelf at chemists, or even at supermarkets. Also, the article states that 5 liters of water per day are recommended by most VLCDs, but the listed source doesn't mention that at all. All the VLCDs that I have seen suggest 2 liters per day (OptiSlim, FatBlaster, Tony Ferguson). PS, Sorry if I haven't added this correctly, I've never added to Wikipedia before. 203.59.123.181 (talk) 06:52, 18 January 2010 (UTC)

Moved to hyphenated title?[edit]

I'm not sure I've ever seen very-low-calorie anywhere. It was moved here with the rather terse edit summary of "logic". I'd like to move it back to very low calorie which I think is much more common. Otherwise, the intro should be rewritten. Any comments? W n C? 07:54, 2 May 2010 (UTC)

I have moved it back. But I'll say that hyphenated titles are a bit over a third of the usage, see google books and google scholar. I also see some people using "very low-calorie diet", but I think that's just confusing. --Enric Naval (talk) 15:51, 8 February 2013 (UTC)
