Easiest Diets to Follow

The easier a diet is to follow, the better the odds of sticking to it. So user-friendliness was one of the factors experts considered in rating the 32 popular programs below. Is the diet filling and tasty? Does it impose stringent requirements such as eating a certain number of times per day? Are unique foods required? The experts put Weight Watchers at the top, viewing it as flexible, tasty and allowing plenty of eating throughout the day.

Dieters can eat whatever they want as long as they don’t exceed their allotted daily points. No foods are forbidden, occasional treats are encouraged, and the plan emphasizes all-you-can-eat fresh fruits and veggies. Experts liked the optional weekly meetings, since support is crucial to compliance. They also applauded Weight Watchers for being realistic, flexible, and filling. It scored more than a full star above the average in this category and was crowned the easiest diet to follow.

Built around prepackaged, home-delivered meals, Jenny Craig takes the guesswork out of dieting. That makes it very easy to follow for those needing portion control and discipline, one expert noted. Meals include favorites like apple cinnamon waffles, lasagna, fish and chips, and cookies, and a Consumer Reports taste-testing panel found them good overall. Like Weight Watchers, Jenny also got praise from the U.S. News experts for structured support, via counselors who work one-on-one with dieters.

Its name is based on the word flexible, so this diet is easy to follow. It landed toward the top of the ranking list, and experts praised it for encouraging dieters to make changes where they can rather than eliminating entire groups of food or following strict rules. Because this isn’t an extreme diet, experts say it’s easy to stick to and reap long-term benefits.

Experts commended the emphasis on diverse foods and flavors. Dieters can tailor the menu to their tastes and preferences, and are even encouraged to have a glass or two a day of red wine. Since there’s no hard and fast calorie range, going hungry isn’t a concern, which helps make the Mediterranean diet moderately easy to follow.

Sticking to the Dietary Approaches to Stop Hypertension (DASH) plan is moderately easy.

Experts also appreciated that DASH doesn’t require tedious prep or unconventional ingredients. An ample supply of online recipes and guides are available to help dieters along.

Another moderately easy program, thanks to heat-and-eat, home-delivered meals. The downside: Dieters must cut back on dining out, and adjust to eating different meals than the rest of the family. Still, Nutrisystem’s simplicity makes it a “good way to get started” on a diet, said one expert.

Developed by the National Institutes of Health, the Therapeutic Lifestyle Changes (TLC) diet is moderately easy to follow.
