The end of the year is nearing, and that means it's time for Google's annual Zeitgeist list -- 2012's most popular searches in a number of categories. We at HuffPost Healthy Living were most excited to read this year's ranking of the ten most commonly searched diets. We don't want to give away the most popular search right off the bat, but the searches did offer us a glimpse into the Googling public's nutritional curiosity -- from supermodel diets to controversial supplements and celebrity preferences, 2012 could be characterized only in its eclecticism.
Read on for a complete list of the diets your fellow Interneters looked for most. Did you search for any of these? Would you try them?
10. Marissa Miller Diet
That Victoria Secret model Marissa Miller's habits comprised the tenth most common diet search shouldn't surprise anyone. And while her looks may have more to do with winning the genetic lottery than any particular affinity for kale juice. That said, if her interview with <em>Women's Health</em> is any indication, <a href="http://www.womenshealthmag.com/life/marisa-miller?page=2">she eats a healthful diet</a>: <blockquote>"I'll cook a batch of brown rice or quinoa and keep it in the fridge, so when I get hungry, I can easily dress it up with olive oil, lemon, and salt and pepper, and then add veggies," says Marisa, who often has zucchini and spinach.</blockquote> But perhaps it was <a href="http://www.womenshealthmag.com/life/marisa-miller?page=2">her admission that she eats in the buff </a>that got all those people clicking.
9. Juicing Diet
Fashionable juice fasts like Blueprint Cleanse, Organic Avenue and the Salma Hayek-backed Cooler Cleanse sound great: reset the mistakes of diets past by eschewing solid food, drinking healthful fruit and vegetable juices for three-to-14 days. But the research proves little in the way of benefit. One 2003 study of <a href="http://www.ncbi.nlm.nih.gov/pubmed/12624474">adult men who fasted for eight days</a> found that although cholesterol, insulin and nonesterified fatty acids were lower after eight days, within a week, those levels had returned to their pre-fasting rates. In other words: there was no lasting benefit to the fast. Or, <a href="http://www.nytimes.com/2010/10/28/fashion/28Cleanse.html?pagewanted=all&_r=0">as New York <em>Times</em> writer and resident juicing tester Judith Newman put it</a>: "You know what it cleans out of you best? The will to live."
8. Feeding Tube Diet
Also known as the K-E Diet (short for Ketogenic Enteral Nutrition), this short-lived trend diet reached a fever pitch in the Google-sphere after the <em>New York Times</em> profiled several women who used a nasogastric feeding tube -- developed to feed the gravely ill or injured -- in order to lose weight. The diet, which is only available at one Florida clinic, works by slowly feeding the dieter with a fat and protein-based solution, accounting for 800-calories per day over a 24-hour period. The developer of the diet, Dr. Oliver R. Di Pietro, allows patients to eat nothing else besides water, unsweetened tea and black coffee. He claims that a person can lose 20 pounds or 10 percent of their weight. As we at Healthy Living <a href="http://www.huffingtonpost.com/2012/04/18/k-e-diet-does-it-work_n_1432790.html">wrote at the height of the diet's publicity</a>: <blockquote>As with any restricted calorie diet, there are risks of headaches, weakness, dehydration and fatigue. Despite this -- and the tube’s dramatic appearance -- the K-E Diet isn't the most dangerous weight loss fad on the block, according to Ren-Fielding. That doesn’t mean it’s a good solution for excess weight. Any quick weight loss scheme -- whether via tube, straw or fork -- is a short-term solution. It will result in dropped pounds, but those come from lost water and muscle mass, rather than fat. The trouble with weight loss of this type is that it returns as soon as the diet ends -- and, it is more likely to return as fat, rather than muscle.</blockquote>
7. NV Diet Pill
The NV Diet Pill, popularized by Carmen Electra, promises to burn fat, tone the body and improve the appearance of skin, nails and hair. There are no clinical studies to back up any of those claims.
6. Miranda Kerr Diet
Supermodel Miranda Kerr's diet is full of healthful, nutritious foods -- <a href="http://www.harpersbazaar.com/fashion/fashion-articles/miranda-kerr-on-personal-style#slide-1">she even became a certified health coach practitioner,</a> she told <em>Harper's Bazaar</em>. "Rather than diet my family instilled in me a real appreciation and passion for good health and organic living. I adopt the 80/20 rule. 80 percent good, 20 percent indulgent and that works for me and my body personally," she said, adding that she drinks warm water with lemon and alkalined water all day, as well as <a href="http://nccam.nih.gov/health/noni">noni juice </a> -- a healthful fruit juice from her native Australia. In the same interview, Kerr said that she did her best to follow Dr. Peter D'Adamo's controversial Blood Type Diet.
5. Adriana Lima Diet
The very new mother recently walked in the Victoria Secret fashion show, prompting some curiosity about the supermodel's super weight loss abilities. According to a report in <em>The Telegraph</em>, she stuck to <a href="http://fashion.telegraph.co.uk/news-features/TMG8872623/Victorias-Secret-show-What-does-it-take-to-be-a-Victorias-Secret-Angel.html">an all-liquid diet for nine days before the event</a>: <blockquote>Lima drinks a gallon of water a day. For nine days before the show, she will drink only protein shakes -- "no solids." The concoctions include powdered egg. Two days before the show, she will abstain from the daily gallon of water, and "just drink normally". Then, 12 hours before the show, she will stop drinking entirely.</blockquote> This isn't so much a diet for health as a crash weight loss strategy for a particular event -- one that may not work and that can cause a host of health problems, like dizziness, nausea and exhaustion. Perhaps not what Googlers had in mind.
4. P.I.N.K. Method Diet
The <a href="http://www.pinkmethod.com/">P.I.N.K. Method</a> was designed specifically for women, and stands for "power, intensity, nutrition, and kardio." Heather Mangieri, MS, RD, a spokeswoman for the Academy of Nutrition and Dietetics <a href="http://www.webmd.com/diet/features/pink-method-review">reviewed the diet program</a> and found that, while some of the advice was great -- such as encouraging physical activity and nutrient-rich foods -- some of the health claims made her uncomfortable. "Even in the best circumstances, many of the claims are overstated and not based on research," Mangieri told WebMD. "Foods are not fat burners and not everyone is going to rejuvenate skin, hair, and nails, and heighten their energy and libido on this plan."
3. Raspberry Ketone Diet
After Dr. Mehmet Oz called raspberry ketones "the number one miracle in a bottle," interest in the supplement skyrocketed. <a href="http://www.huffingtonpost.com/2012/03/29/raspberry-ketone-dr-oz_n_1388258.html">As we wrote previously</a>, raspberry ketones stimulate the production of adiponectin, a hormone found in fatty tissue that improves our ability to metabolize fat. Studies show that thin people have higher levels of adiponectin than overweight and obese people. But does that mean that taking the supplement will actually result in weight loss? That logical leap has yet to bear out in the research, which has only been conducted on mice and not humans.
2. Beyond Diet
Founded by New Jersey-based nutritionist, Isabel De Los Rios, the Beyond Diet is an online diet system and community that is based on eating for body type, portion control, ratios of fat to carbs to protein and "clean" eating -- a term used by many dieters to indicate food made from organic, whole ingredients. The system costs $47 and includes an online community and a newsletter from De Los Rios. Diet chat boards are full of people who feel that <a href="http://www.myfitnesspal.com/topics/show/514207--beyond-diet-have-you-tried-it-looking-for-opinions">the advice doesn't warrant the price tag</a> as most of the tips are in line with other systems out there, but that certainly doesn't mean that it's bad advice. <blockquote><strong>Correction:</strong> A previous version of this article erroneously listed Beyoncé's diet as the second most-searched for diet term of 2012. We regret the error.</blockquote>
1. Michael Phelps Diet
Record-breaking, history-making Olympic great Michael Phelps is nearly as well known for his <a href="http://www.huffingtonpost.com/2012/08/06/michael-phelps-diet-furious-pete_n_1746922.html">reported 12,000 calorie a day training diet</a> as he is for prowess in the pool. <a href="http://content.usatoday.com/communities/gameon/post/2012/05/michael-phelps-12000-calorie-diet-just-a-myth/1#.UMe4rpPjnMA">Never mind that his actual game-time calorie intake is a more modest 4,000,</a> according to <em>USA Today</em>. Given the nature of his carbo-loading ways (necessary for his massively rigorous training schedule), we can only imagine that this diet search was merely a way to satisfy curiosity and not a search for meaningful health information.
