I'm surprised that there's no broad topic on "diets" in CathInfo [*].  So I'm starting one.  I'm not an advocate of any diet in particular, so this topic is for members who are advocates--or critics--to inform or discuss with their fellow members [×] [♦].

• ‘Croix de Fer’ (possibly eventually ‘Full Sugar Brah’): All sugar, all the time.  Okay, to be fair, his diet is more-or-less as described in the external video "Cure Type 2 Diabetes With Sugar & White Rice - Dr. McDougall", which he embedded in the topic he originated bearing the same name (January 22, 2018, 22:25:59 [CST]).  <https://www.cathinfo.com/health-and-nutrition/cure-type-2-diabetes-with-sugar-white-rice-dr-mcdougall/>, which interested enough members to extend far into a 5th C.I. page.  Including praise by Ladislaus for the Atkins Diet, based on experiences of "several people I know".  Then sharp criticism by ‘Croix de Fer’ as the "Fatkins Diet" ("Dr. Fatkins died obese and from a heart attack & hypertension").  That being only the 1st page, and on it went.

• "Keto" Diet: Perhaps authoritatively discussed by Northwestern Medicine®, which seems tightly connected to the B1G university in metro Chicago: "Pros and Cons of the Ketogenic Diet".  <https://www.nm.org/healthbeat/healthy-tips/nutrition/pros-and-cons-of-ketogenic-diet>.

• Atkins Diet: Reputedly a longer established "ketogenic" diet than what's popularly labelled as such, e.g.: <https://www.everydayhealth.com/diet-nutrition/atkins-diet.aspx>.

• Modified Atkins Diet (MAD)?

• Mediterranean Diet?

• Paleo Diet?  For discussion: <https://www.cathinfo.com/health-and-nutrition/the-paleo-diet/>, which interested enough members to extend to the end of a 2nd C.I. page.  Presented, e.g.: <https://www.everydayhealth.com/diet-nutrition/the-paleo-diet.aspx>.

• Veganism?  Discussion: <https://www.cathinfo.com/health-and-nutrition/veganism-acceptable-for-catholics/>, which interested enough members to extend far into a 6th C.I. page; also in the unrevealingly titled "monks" from 8 years ago: <https://www.cathinfo.com/health-and-nutrition/monks/>.

• Weight Watchers Diet?  Is this a distinct diet, or really merely a commercial enterprise for which continuing cost is a major issue? (e.g., ‘Viva Cristo Rey’, "The Paleo Diet", July 20, 2013, 09:09:34)

• "Whole30" Diet?  E.g.: <https://www.everydayhealth.com/diet-and-nutrition/diet/whole30-program-what-know-before-starting-diet-plan/>.

• De facto Judaizer, Kosher, or Halal Diet?  Discussion: <https://www.cathinfo.com/health-and-nutrition/why-you-should-never-eat-pork/>, which interested enough members to extend, with strong opinions, to early in a 3rd C.I. page.  Advocates also appeared in the Veganism topic (q.v.).

• ‘poche’: The ‘poche’ diet?  Maybe more like the Spheroid-Silhouette Diet?  The topic he originated in which he inquired about "The Paleo Diet" (q.v.) was almost exactly 7 years ago.  Is there any rhyme or reason to the combinations of real food and ersatz food that he more recently claims to have eaten, in his replies for "whats your dinner?"  Could all that be a long-running hoax?

-------
Note *: Unlike some CathInfo members who are credited with thousands of posts who cluelessly duplicate topics that have been newly originated within what's often the past several days by a fellow member, I used the searching privileges granted by C.I. to Evil Google to verify the presence or absence of C.I. topics about diets.

Note ×: Of course, I have no authority to force C.I. members to post here instead of originating their own topics.  But individual topics on ingredients beneficial to nutrition seem to age off the "Health and Nutrition" index page rather quickly, e.g., a topics whose last reply was on July 17, thus barely 1 week old, has already aged out to the 2nd page of the index.  And maybe, just maybe, having such a broad topic stay visible (pinning, anyone?) can reduce the off-topic sidetracking that's common in topics that were plainly originated to discuss unrelated subjects.  I encourage members to insert links here in this topic to topics in C.I. that they've newly originated  in C.I. are devoted to a particular diet.

Note ♦: I casually chose <https://www.everydayhealth.com/> as a more-or-less authoritative source, altho' readers might disagree with its apparent conformance to establishment cardionutrition.  In summary, EDH "looked o.k.", but I didn't check any more deeply.  So I welcome recommendations of alternative sources, esp. those in the form of written words.

Including praise by Ladislaus for the Atkins Diet, based on experiences of "several people I know".  Then sharp criticism by ‘Croix de Fer’ as the "Fatkins Diet" ("Dr. Fatkins died obese and from a heart attack & hypertension").  That being only the 1st page, and on it went.

Haha.     ‘Twas an epic debate indeed!

Robert Atkins did not die due to his diet.

Atkins died on April 17, 2003, at the age of 72.^[4] Nine days prior to his death, Atkins fell and hit his head on an icy New York sidewalk. At New York's Weill Cornell Medical Center, where he was admitted on April 8, he underwent surgery to remove a blood clot from his brain but went into a coma and died from complications. He spent nine days in intensive care before dying on April 17, 2003

He did have a heart condition, cardiomyopathy, which had been caused by a virus.  This is what he looked like shortly before his death, clearly not obese.  
  

Technically, he was obese at the time of his death, due to severe fluid retention during his coma when he was on a glucose drip.  Obviously, living on pure sugar is not part of the Atkins diet.

The diet that I personally follow is the carnivore diet.  I eat only animal products, mostly meat.  I see this more as a healing diet than a weight loss diet, although I did lose significant weight.  I lost around 50 pounds, reversed pre-diabetes and Fatty Liver disease, and improved my energy and general health.  I was very sick before I went on this diet and it caused a dramatic improvement.  I would recommend it to others with health problems, but I simply for weight loss, it is rather extreme.
