From celebrity-endorsed to science-backed, finding the best diet for your body and lifestyle can be an exercise in frustration—definitely not the kind of exercise you need right now! To make your search easier, we've pulled together the 10 most popular diets based on which ones have consistently ranked highest on the annual U.S. News & World Report rankings, WebMD, and other current diet lists. Just know this: It's not about finding out which diet is the most popular overall but which one fits your goals and lifestyle the best. After all, the best diet for you is the one you can stick with (and enjoy)!


First, a little background: Eric Westman, MD, director of the Duke Lifestyle Medical Clinic, explained to Health in a previous interview that in order to successfully follow the keto diet, you need to eat moderate amounts of protein, reduce your carb intake, and increase fats. When you reduce your carb consumption, your body turns to stored fat as its new fuel source—a process called ketosis. To stay in ketosis, followers of the keto diet must limit their carbs to 50 grams a day, Dr. Westman says.

Urine ketone data were missing in a median of 4 participants (range 0–8) at any given visit. The proportion of participants with a urine ketone reading greater than trace was 1 of 17 participants at baseline, 5 of 17 participants at week 2, and similar frequencies at subsequent visits until week 14 when 2 of 18 participants had readings greater than trace and week 16 when 2 of 21 participants had readings greater than trace. During the study, only 27 of 151 urine ketone measurements were greater than trace, with one participant accounting for all 7 occurrences of the highest urine ketone reading (large160).
Reduced hunger. Many people experience a marked reduction in hunger on a keto diet. This may be caused by an increased ability of the body to be fueled by its fat stores. Many people feel great when they eat just once or twice a day, and may automatically end up doing a form of intermittent fasting. This saves time and money, while also speeding up weight loss.

In September 2018, researchers at Harokopio University in Athens released a study that suggests adhering to the Mediterranean diet can promote better sleep, specifically in older adults. While more research needs to be conducted to determine exactly how and why the Mediterranean diet improves sleep quality, senior study author Dr Mary Yannokoulia suggested that the connection could have to do with the presence of the sleep-promoting hormone melatonin in foods like olive oil, fish and fruit.


The keto diet is intriguing because it appears to run counter to the prevailing wisdom about the importance of lowering fat intake to prevent diabetes and heart disease, says a co-author of the new study, Gerald Grandl, PhD, a postdoctoral researcher at the Institute for Diabetes and Obesity at the Helmholtz Center in Munich. ETH Zurich conducted the study with University Children's Hospital Zurich.

Interested in following a more historical approach to eating? The Primal Blueprint is similar to the Paleo diet, which has roots in how our long-ago ancestors supposedly ate. This plan ditches grain, sugars, and processed foods while focusing on clean eating with plenty of protein (both animal- and plant-based), lots of vegetables, fruits, and healthy fats. The Primal Blueprint acknowledges other health factors too, advocating for lots of low-intensity activity, some high-intensity exercise, strength training, and plenty of sleep.

Roussell explains that when we get too hungry, our bodies secrete a hormone called, ghrelin, which controls our hunger and appetite. If too much ghrelin is released, we get hangry and will grab pretty much anything. Before bed, however, Roussell says going to sleep a bit hungry can actually be beneficial. “Going to be hungry may actually help you sleep better as ghrelin makes your body more responsive to compounds in your brain that aid in sleep.”
Speaking of flavonoids, the waist-whittling compounds also exist in higher concentrations in red fruits such as watermelon, Pink Lady apples, and plums, meaning they also have the power to induce weight loss. In fact, a 2016 study in the journal BMJ found that people who eat a diet rich in flavonoid-heavy food tend to gain less weight, which could be promising seeing as many people tend to put on pounds as they age. In addition, anthocyanin, a specific flavonoid compound that gives red fruits their color, has been shown to reduce fat-storage genes.
A: The most common ways to track your carbs is through MyFitnessPal and their mobile app. You cannot track net carbs on the app, although you can track your total carb intake and your total fiber intake. To get your net carbs, just subtract your total fiber intake from your total carb intake. I have written an article on How to Track Carbs on MyFitnessPal.
Switch to Lighter Alternatives. Whenever you can, use the low-fat versions of salad dressings, mayonnaise, dairy products, and other products. "You can trim calories effortlessly if you use low-fat and lighter products, and if the product is mixed in with other ingredients, no one will ever notice," says Magee. More smart substitutions: Use salsa or hummus as a dip; spread sandwiches with mustard instead of mayo; eat plain roasted sweet potatoes instead of loaded white potatoes; use skim milk instead of cream in your coffee; hold the cheese on sandwiches; and use a little vinaigrette on your salad instead of piling on the creamy dressing.
But what I think is funny is that the keto diet has been staring us in the face forever. Look at Inuit tribes that survived off of blubber in a region that grows next to nothing most of the year. Yet their people didn’t die out or show signs of metabolic disorders or heart disease until introduced to the modern western diet that prioritizes carbohydrates over fat. Here is an interesting link, however I find the conclusion disheartening and frankly more than a little suspicious. (Basically the people in charge decided to drop the study and introduced a bunch of “what about…” questions to obfuscate a clear pattern in observation across many indigenous people from across the face of the planet and decided the outcome “wasn’t enough” to introduce into public policy…)
"We recommend against 'dieting', which is invariably a short-term solution," Dr. Gonzalez-Campoy, tells EndocrineWeb, "and since weight loss may be accomplished by a reduction in calories by any means, a ketogenic diet that restricts carbs is simply shifting the calories away from foods that typically demand insulin as in both of these studies.1,2  
Bingo!! It’s all about the $. The info graphic at the very beginning is labeled Keto-Paleo. And is misleading. Contrary to popular belief the Paleo diet is plant based. It restricts carbohydrate and dairy consumption based on foods that cause an inflammatory response in the body. Keto restricts foods that cause a blood sugar spike two very different purposes. American nutrition is very obviously broken and any recommendation tied to a money making association should be taken with a grain of salt because you can bet there are $$ strings attached. Usually big Pharma funding.

Wouldn’t it be great if life came with a magic remote control that made the bad parts speed up and the good parts slow down? You could hit FF at the beginning of every workday, and RWD at the end of awesome date. All the vacations, holidays and parties could move at the pace of a Kenny G song, and all the endless conference calls could spin by faster than Nicki Minaj’s hairstyles.


As both study groups acknowledge, additional research is needed to tease out any and all of the factors that may be producing the weight loss and decrease in HbA1c, says Dr. Gonzalez-Campoy, for example  there may be other mechanisms of action that are helping these individuals to achieve weight loss, including changes in the gut microbiome, increased insulin sensitivity, enhanced leptin response, and decreased ghrelin levels, each of which contribute to weight loss.
Hi Kelly, All packaged foods will have a nutrition label that list the macros per serving, including fat, protein and cabrohydrates. Net carbs, which is what most people look at for low carb and keto, are total carbs (the amount on the label) minus fiber and sugar alcohols, as explained in the article above. I have a low carb food list here that gives you a full list of all the foods you can eat, and the net carbs in each. You can also sign up above to be notified about the meal plans, which are a great way to get started.
“I think the caution with a low-carbohydrate diet is the idea that it’s very restrictive,” Zeratsky says. “When you start getting into the very low carbohydrates, when you’re talking about 20 grams, which for some people would be a cup of [starchy] vegetables. … If there is someone who is interested in it, it’s very important they understand what a low carbohydrate diet means in a practical sense.”
I have been a type 1 diabetic for most of my life. I live a very active lifestyle of long distance running and hiking. I’ve always had a very healthy diet, but would still have those after meal blood sugar spikes that would leave me feeling unwell. I decided to try the keto diet to see how my blood sugar did It’s been amazing. I’ve cut my insulin in half and my head is clear. I no longer have the brain fog. I sleep better and have more energy. I have been doing it for a year and have no desire to go off of it.
When you’re eating the foods that get you there (more on that in a minute), your body can enter a state of ketosis in one to three days, she adds. During the diet, the majority of calories you consume come from fat, with a little protein and very little carbohydrates. Ketosis also happens if you eat a very low-calorie diet — think doctor-supervised, only when medically recommended diets of 600 to 800 total calories.
