What the diet advocate says: The food baby of the US reality couple Heather and Terry Dubrow (she stars in the Real Housewives of Orange County; he’s a plastic surgeon starring in a show called Botched). ‘As opposed to the keto diet that aims to get you to a ketogenic state of using fat as fuel, which isn’t healthy or sustainable in my opinion, interval eating helps you go into a fat-burning state that leads to increased energy and cell renewal - a process called autophagy, the toxin-eating phase,’ says Terry.
What the expert says: ‘Paleo does promote the consumption of fresh ingredients over salty, processed meats. It also advocates a high consumption of fruit and vegetables, which is no bad thing. Research published in the journal Nature suggests that following this kind of diet can improve blood pressure, insulin resistance and cholesterol levels. That said, it is incredibly restrictive, and cutting out dairy, cereal foods and starchy carbohydrates will likely leave you low on fibre, calcium and iodine.’
The best diet for losing weight is Weight Watchers, according to the experts who rated the diets below for U.S. News. Volumetrics came in second, and the Flexitarian Diet, Jenny Craig and the vegan diet were third on this overall weight loss ranking list, which takes into account short-term and long-term weight loss scores. Some other diets performed as well or better in our rankings for enabling fast weight loss, but long-term weight loss is more important for your health.

Anecdotally, many people say they feel great on the Paleo diet -- losing weight and lowering health markers such as blood pressure and cholesterol. However, like most programs, many simply don't stick with this way of eating over the long term -- they keep lapsing and going back -- the same issue we see with all eating plans. Again, there is no formal "Paleo" diet, but there are plenty of books and online resources for anyone interested in exploring the idea.

U.S. News’s Best Diets rankings are put together by a panel of nutritionists, dietary consultants, and doctors specializing in diabetes, heart health, and weight loss. Each member of the panel scored all 41 diets in seven different areas, including how easy they are to follow, how well they protect against chronic disease, and how likely it is that followers will actually lose weight and keep it off.


To encourage ketone production, the amount of insulin in your bloodstream must be low. The lower your insulin, the higher your ketone production. And when you have a well-controlled, sufficiently large amount of ketones in your blood, it’s basically proof that your insulin is very low – and therefore, that you’re enjoying the maximum effect of your low-carbohydrate diet. That’s what’s called optimal ketosis.

Take a look at any collegiate rower’s body and you’ll surely be envious of their athletic, v-cut frame. “Rowing makes the list because it is a great way to incorporate the upper and lower body in a relatively low-stress manner on your joints and ligaments,” explains Ryan. “It’s also a great way to work the posterior chain.” Following a moderate pace on the rowing machine can burn upwards of 800 calories per hour for an 180-lb guy, but increasing the intensity with short sprints will get that number well over 1,000 calories per hour very quickly.

What the diet advocate says: 'The key components of a Mediterranean diet are lots of vegetables, olive oil, oily fish and nuts, with no calorie restrictions. Combine that with cutting down on sugar, which was traditionally a rarity in the region, and you’ve got the base of the Mediterranean diet right. And if you get the base right you can eat a little of whatever else you like,' says Consultant Cardiologist Dr Aseem Malhotra.


The Mayo Clinic Diet is generally safe for most adults. It does encourage unlimited amounts of vegetables and fruits. For most people, eating lots of fruits and vegetables is a good thing — these foods provide your body with important nutrients and fiber. However, if you aren't used to having fiber in your diet, you may experience minor, temporary changes in digestion, such as intestinal gas, as your body adjusts to this new way of eating.

Stephen Colbert may be on to something. UCLA Center for Human Nutrition researchers divided study participants into two groups, each of which were fed a nearly identical low-cal diet for 12-weeks. The only difference between the groups was what they were given to eat as an afternoon snack. One group ate 220-calories of pretzels while the other group munched on 240-calories worth of pistachios. Just four weeks into the study, the pistachio group had reduced their BMI by a point, while the pretzel-eating group stayed the same, and their cholesterol and triglyceride levels showed improvements as well.
Caloric intake: Some people need more calories because of metabolic issues or high activity levels, and low-calorie plans might be insufficient. While it is true that less calories usually means more weight loss, and it’s normal to feel hungry some of the time while dieting, some diet plans are too strict and leave you feeling uncomfortably hungry most of the time. Consider if a diet plan will keep you satisfied.
The best diets promote inclusivity over exclusivity and rely heavily on produce. Highly restrictive diets depend on immediate weight loss to motivate you — but some may backfire entirely and others may leave you fully missing out on nutrients and experiences. Think about what works best for you before trying any new approach to eating, and use that as your framework for building healthier eating habits that stick.
This principle involves eating low-energy-dense foods and can help you lose weight by feeling full on fewer calories. Healthy choices in each of the other food groups in moderate amounts make up the rest of the pyramid — including whole-grain carbohydrates, lean sources of protein such as legumes, fish and low-fat dairy, and heart-healthy unsaturated fats.
“Starting slow and working your way up is better than overdoing it and giving up,” says Gagliardi. “I like the idea of attaching the new behavior of taking a walk to an existing behavior.” An easy way to approach it: Commit to going for a quick 10-minute walk after dinner, and slowly increase the time as you become more comfortable with daily movement.
Most people who want to lose weight have more than 12 pounds to lose. That’s why even the best weight loss drug in the world can only be an optional complement to other treatment. That’s why this piece of advice is number 18 out of 18. It may be a helpful addition for some people, but the advice higher on the list is what can make the biggest difference, by far.
Eat more protein. Protein is required by the body to repair damaged cells and plays a vital role in growth and development.[3] But it can also play a role in weight loss. Diets high in protein tend to make people feel fuller, and when paired with a reduction in carbohydrate intake these diets can help with weight loss.[4] However, it's important to remember that not all sources of protein are good for you: red meat and full-fat dairy products, though high in protein, can also increase the risk of heart disease.[5] Good sources of protein include:[6]
Have you ever decided to skip a meal to cut back on your daily calorie count? Despite saving a few calories in the moment, this strategy almost always backfires. When you skip breakfast, or any meal, you'll begin to experience excessive hunger that can lead to craving unhealthy foods—and lots of them. You may also eat faster than you normally do after skipping a meal, causing you to miss the warning signs that you're full and resulting in overeating.
Yes! I also work night shift so I can ride (three day eventer) during the day… I sleep in the afternoon usually. My diet is all kinds of weird now that I am awake at night. Any good suggestions for us? I usually switch back to a day schedule on my days off…. again making eating strange… one day I will hardly eat anything and then the next too much, sort of depends on how long I’m awake!! I am really new to Fitbit so I am just learning some of these things about my diet. This is great!! Your diet plan looks great! I will try to mix it up for my schedule but any suggestions would be appreciated! Thank you!
There’s a reason everyone harps on about protein: Not only does it help keep you full, but it’s also responsible for repairing the tiny tears caused by strength training in your muscles. This helps them grow bigger and stronger, nudging out body fat in the process. As a general rule of thumb, aim to get at least 70 grams of protein throughout the day, says Dr. Cheskin. (These high-protein foods can help you reach that goal.)
There’s a reason the jump rope is a mainstay in a boxer’s training regimen: it’s cheap, easy to do, increases foot speed, and burns a ton of calories. Think of your favorite boxers, wrestlers, and fighters—they all jump rope. “Jumping rope not only enhances your footwork, shoulder strength, and coordination, but also simulates sprinting, allowing you to burn as much as 500 calories in just 30 minutes,” says Ben Boudro, C.S.C.S., owner of Xceleration Fitness in Auburn Hills, MI..

A new player in the weight loss program space, Noom packs a lot of behavioral psychology into one sophisticated app. It aims to help you identify and break bad habits, and have some fun doing it. The powerful app echoes Weight Watchers’ successful community approach, but outleagues that program in terms of learning resources. While it’s the more expensive of our two favorite programs, it’s the richer when it comes to virtual experience — with personalized lessons, tasks, and support that made us look forward to opening up the app.
