Some of the diets on this list are equally odd. What even are the Shepherd’s and Optavia diets? Here are all the diets searched most often on Google this year — many of which we, admittedly, had to Google.

Keto Diet

If you haven’t heard of the keto diet, you’re living under a boulder. Celebrities like Vanessa Hudgens and Kourtney Kardashian swear by it. But what is the keto diet? Essentially, it’s a sort of extreme carb restriction that results in ketosis, a nation in which your body must resort to burning fat for fuel. Ketosis can induce your breath smell really bad — but if you can manage that, here are some health factors to consider before you try it .

Dubrow Diet

The Dubrow Diet is a diet pioneered by writers of the book “The Dubrow Diet: Interval Eating to Lose Weight and Feel Ageless.” Heather Dubrow, co-author, is a former starring of Bravo’s “The Real Housewives of Orange County.” She teamed up with her husband( a plastic surgeon) to come up with a diet that, she says, answers everyone’s question about how they manage to stay so “ageless and fit.” Their secret has nothing to do with plastic surgery, apparently — it’s a specialized sort of intermittent fasting. It involves a list of permitted foods and three stages of interval eating.

Noom Diet

Noom is actually not a diet, but an app. It’s been called “Weight Watchers for millennials, ” and it essentially offers meal schemes, fitness tracking, and weight loss motivating techniques on your telephone. It involves taking quizzes on health-related topics and comes with an assigned health coach enabling you to through.

Carnivore Diet

Modern science may work under the assumption that humans are omnivores, but these meat-hungry dieters disagree. The carnivore diet merely might be the wildest weight loss fad of all time. Supporters of the diet live by the motto: Eat meat, drink water. They all meat all the time — no veggies allowed. Red meat is highly favor over anything that might be considered( gasp !) lean.

Mediterranean Diet

This diet has been called one of best available diets by modern health criteria, largely due to its link to a reduced hazard of dementia and other cancers. It involves eating lots of healthy fats from sources such as fish and olive oil alongside fruits, veggies, poultry, and whole grains. It also is in favour of frequent( but moderate) pours of wine — which, thankfully, has its benefits regardless of whether you’re on the diet or not.

Optavia Diet

You might have heard of the old version of the Optavia diet, Medifast. Optavia is essentially the updated version. Like Medifast, Optavia involves eating pre-packaged meals and snacks called “Fuelings” that you must purchase from the company. Buddy Valastro, host of “Cake Boss, ” allegedly lost weight on this diet. Guess he also cut back on cakes, since they weren’t Optavia-approved. Unless you want to eat nothing but “Fuelings” for the rest of your life, though, this diet is probably not sustainable.

Dr. Gundry Diet

Kelly Clarkson did it for medical reasons , not weight loss — she has an autoimmune cancer. But despite her insistences, many have followed in her footsteps hoping to shed some pounds. The diet comes from the mind of Dr. Steven Gundry( of whom Dr. Oz is a big fan ), who wrote the book “The Plant Paradox.” His stance is that lectins, a plant protein found in grains, beans, legumes, nuts, fruit, nightshade vegetables, and dairy, are the root of almost all of America’s health problems. His diet eliminates almost all lectins, letting simply a very small listing of foods to eat instead. When other health experts heard about the diet, however, the latter are more than a bit skeptical. Gundry also is a contributor for Goop, which doesn’t have the cleanest track record, to say the least.

Fasting Diet

There is no single “fasting diet, ” but( unfortunately) many. Some fasting diets are extreme and deadly. But other less extreme fasting diets are popular because they seem benign. One of the most popular of these fasting diets is called “intermittent fasting, ” and it involves feeing all your food for the working day within a set window so that you may fast for the remainder. The jury’s out on whether this diet genuinely works or not — here’s what the experts had to say.

FODMAP Diet

The FODMAP diet originated as a treatment for irritable bowel disorder( IBS ). It involves cutting out all high-FODMAP foods, which are foods that contain certain carbohydrates that cause digestive distress in some people. These foods include common staples such as wheat, garlic, mushrooms, apples, beans, brown rice … The listing goes on and on. It’s a lot of healthy foods. Eliminating all of these things wholly is extremely difficult and requires constant careful attention. For people without IBS, the social sciences shows that a FODMAP diet can do far more damage than good. The foods eliminated are not only highly nutritious, but also contain prebiotics, compounds that feed the very best bacteria in your intestine. And even for those with IBS, the diet was never meant to be long-term — its pioneers actually advocate for a short-term use in order to weed out foods that may be causing problems. The official FODMAP Protocol comes with a “reintroduction phase” wherein many( if not all) foods are slowly reintroduced.

The Shepherd’s Diet

Zero sheep were harmed during the course of its produce of the Shepherd’s Diet. This diet got its name because of the book behind it: “The Shepherd’s Diet – A Biblically Inspired 7 Step System to Lose Weight, Look Great, and Feel Younger.” The volume claims that “scientific evidence and God’s guidelines on what to eat are in prefect sync in this food plan.” Those who buy the book have the option to purchase add-ons such as “’The Moses Secret’ Fat Loss Protocol” and the “What Would Jesus Eat Grocery Field Guide.” Those guides are surely very informative, but here’s the gist: It’s low-carb, high-fat, moderate-protein eating with a side dish of prayer at every dinner. It’s your bellow whether or not you want to try this diet plan.

So there you have it: the most Googled diets of 2018. The last of which use text that date back to biblical periods! Nutrition science may not have as much modern influence as you think — here are some other wacky wellness fads that were inexplicably popular this year .
