We pulled the top 14 of the best commercial diets (marketed to the public for profit) and the top 12 of the best diets overall. We also threw five of the most popular diet apps into the mix. Since these are largely tracking devices that don’t espouse unique eating habits, they don’t appear to meet US News’ definition of diet, but are still potentially effective weight loss tools.
We know that shedding unwanted pounds used to mean giving up your favorite foods, logging hours at the gym, and being hungry (and hangry) all the time. Fortunately, dropping a dress size (or two) doesn’t have to be that complicated or torturous. Sure, losing any significant amount of weight requires lifestyle changes and some hard work, but it all boils down to simple choices.

Avoid fad diets. It's never a good idea to trade meals for shakes or to give up a food group in the hope that you'll lose weight — we all need a variety of foods to get the nutrients we need to stay healthy. Avoid diet pills (even the over-the-counter or herbal variety). They can be dangerous to your health; besides, there's no evidence that they help keep weight off over the long term.


Barley got its hunger-fighting reputation after Swedish researchers found that eating barley or rye kernels for breakfast kept blood sugar on an even keel. That's because the carbs in barley and rye kernels are "low glycemic index," meaning they raise blood sugar more slowly than some other carbohydrate foods. This helps you avoid a spike, and then a drop, in blood sugar, which can leave you feeling famished.
You know the kind, says Jillian: "Everyone's like: 'Give up carbs!' 'Give up fat!' 'Wait, no, now I'm taking pills!' None of them are manageable long-term—and they wreak havoc with your metabolism! Because you're either starving yourself or you're cutting out a major food group. Then you go back into weight-gain mode, but it's even worse, because your body has adjusted to all that crazy fad crap."
The color of your plate may seem like the last thing you'd need to consider when it comes to losing weight, but it can play a surprisingly big role in how much you eat, according to a 2012 Cornell University study. Researchers discovered that when the food and plate color have low color contrast (like pasta with red sauce on a red plate), diners served themselves 22% more from a buffet than when there was a higher color contrast (like pasta with red sauce on a white plate).
And lastly, you can't expect big results if you only make small changes. If you really want to lose weight, you need to tackle each of the three tasks if you want to see real results. Record your daily calorie intake, measure your weekly workouts and stay accountable to a health coach or other professional to reach your weight loss goal and keep the weight off for good.
Counseling and community: Think about whether you need one-on-one guidance from an expert or a supportive diet-related community to succeed on a weight loss program. Some people prefer to go it alone or involve their friends or family rather than a forum, but others enjoy finding acceptance and encouragement from others who are using the same program.
The authors wanted to compare low-fat vs. low-carb diets, but they also wanted to study genetic and physical makeups that purportedly (their word) could influence how effective each type of diet will be for people. Previous studies had suggested that a difference in a particular genetic sequence could mean that certain people will do better with a low-fat diet. Other studies had suggested that insulin sensitivity may mean that certain people will do better with a low-carb diet.

After dinner, wash all the dishes, wipe down the counters, turn out the light, and, if necessary, tape closed the cabinets and refrigerator. Late-evening eating significantly increases the overall number of calories you eat, a University of Texas study found. Learning how to stop late-night snacking can save 300 or more calories a day, or 31 pounds a year.
Being in optimal ketosis for a prolonged period of time (say, a month) will ensure that you experience the maximal hormonal effect from eating a low-carb diet. If this doesn’t result in noticeable weight loss, you can be certain that too many carbs are NOT part of your weight issue and not the obstacle to your weight loss. There are, in fact, other causes of obesity and being overweight. The next three tips in this series might help you.
Weight Watchers is a household name for the majority of Americans. Why? Because it works. In fact, the U.S News and World Report named this the best weight-loss diet for 2016 in their annual rankings — and with good reason. The balanced program lets you eat what you want, track your choices via a points system, and build a weight loss support network with fellow Weight Watchers' members.
