The government-endorsed Dietary Approaches to Stop Hypertension (DASH) snagged the top spot.
- 1. DASH DietFlickr/Wikimedia: Magic MadzikDASH was developed to fight high blood pressure, not as an all-purpose diet. But it certainly looked like an all-star to our panel of experts, who gave it high marks for its nutritional completeness, safety, ability to prevent or control diabetes, and role in supporting heart health. Though obscure, it beat out a field full of better-known diets.
- 2. TLC DietalamyTherapeutic Lifestyle Changes, or TLC, is a very solid diet plan created by the National Institutes of Health. It has no major weaknesses, and it’s particularly good at promoting cardiovascular health. One expert described it as a “very healthful, complete, safe diet.” But it requires a “do-it-yourself” approach, in contrast to the hand-holding provided by some commercial diets.
- 3. (Tie) Mayo Clinic DietThis is the Mayo Clinic’s take on how to make healthy eating a lifelong habit. It earned especially high ratings from our experts for its nutrition and safety and as a tool against diabetes. Experts found it moderately effective for weight loss.
- 3. (Tie) Mediterranean DietFlickr:missmoniquitaWith its emphasis on fruits and vegetables, olive oil, fish, and other healthy fare, the Mediterranean diet is eminently sensible. And experts’ assessments of it were resoundingly positive, giving this diet an edge over many competitors.
- 3. (Tie) Weight Watchers DietGettyWeight Watchers is a smart, effective diet. It surpassed other commercial diet plans in multiple areas, including short- and long-term weight loss and how easy it is to follow. It’s also nutritionally sound and safe, according to experts. Among its pluses: An emphasis on group support, lots of fruits and vegetables, and room for occasional indulgences.
- 6. (Tie) Flexitarian DietShutterstockThe Flexitarian diet, which emphasizes fruits, veggies, whole grains, and plant-based protein, is a smart and healthy choice. It outperformed many of its competitors, with particularly high scores in nutritional completeness, easiness to follow, and long-term weight loss. One panelist noted that this diet is “a nice approach that could work for the whole family,” and another described it as a “very good” plan.
- 6. (Tie) Volumetrics DietalamyVolumetrics outperformed its competitors in many categories. It earned particularly high marks for being safe and nutritious, and experts said it could have a positive effect on heart health and diabetes. “This is an eating plan that everyone can benefit from,” one expert said.
- 8. Jenny CraigGettyJenny Craig drew praise from experts for being easy to follow, nutritionally complete and safe, and for offering dieters emotional support. But these experts were lukewarm about its potential to bolster heart health or help diabetics. Experts also noted that Jenny Craig’s cost could be a roadblock for some.
- 9. (Tie) Biggest Loser DietAPThe Biggest Loser diet received high marks for short-term weight loss, safety, and soundness as a regimen for diabetes, and it was rated moderately effective for heart health. But many panelists felt that in a sea of diets, it’s not overly special, and one said it’s merely “capitalizing on the name” of the popular TV show.
- 9. (Tie) Ornish DietalamyThe Ornish diet got a mixed reaction from experts. On one hand, it’s nutritionally sound, safe, and tremendously heart-healthy. On the other, it’s not easy for dieters to adhere to the severe fat restriction the diet demands.
- 11. (Tie) Traditional Asian DietShutterstockThe Asian diet is a reasonable choice for an eating pattern, landing around the middle of the pack of ranked diets. Experts handed out high marks in nutrition and safety, but doubted the plan’s ability to deliver short- or long-term weight loss.
- 11. (Tie) Vegetarian DietFlickr:little blue henAs a health diet, vegetarianism is solid. It’s decent at producing rapid weight loss, according to experts, and is strong in other areas, such as heart health and nutritional completeness, that arguably are more important.
- 13. (Tie) Anti-Inflammatory DietShutterstockWhile the Anti-Inflammatory diet itself is nutritionally sound, experts expressed concern that it’s needlessly complicated, lacks supervision or feedback, and boasts unsubstantiated claims like the benefits of supplement use. “Most Americans would benefit from adopting many of these principles, especially increasing fruits and vegetables,” one expert said. “What is lacking is scientific evidence that this diet will reduce inflammation in the body and that weight loss results from following it.”
- 13. (Tie) Slim-FastGettySlim-Fast is a reasonable approach to dieting, experts concluded. It outscored a number of competitors on weight loss and as a diabetes diet, and being highly structured, it’s fairly easy to follow. But it scored lower than many other diets on heart health.
- 13. (Tie) Spark Solution DietIn its Best Diets debut, the Spark Solution landed in the middle of the pack, receiving 3.3 stars overall and tying with Dr. Weil’s Anti-Inflammatory Diet and the Slim-Fast Diet. Panelists believe the Spark Solution will lead most dieters to weight loss, given it’s tried-and-true principals of well-rounded meals, calorie reduction and exercise. A few experts pointed out that the diet is “not particularly novel,” and even more were not convinced of the long-term benefits of the Spark Solution, given the super structured plan only maps out dieters’ first two weeks of the plan.
- 16. (Tie) Flat Belly DietShutterstockThe Flat Belly diet landed in the middle of the pack because most of its scores from the experts were right around average. It did get high marks in safety and nutrition.
- 16. (Tie) NutrisystemalamyNutrisystem sits near the middle of the standings. It’s quite safe, easier to follow than many other diets and has few nutritional deficiencies, according to experts. As a heart diet, it’s off the mark.
- 18. (Tie) Abs DietThe experts found the Abs diet moderately effective for quick weight loss and middle of the road in most other respects. They took issue with the company’s claim that dieters can drop up to 12 pounds of belly fat in two weeks and questioned the evidence behind some of its tactics.
- 18. (Tie) Engine 2 DietExperts handed out a below-average 3 stars. Though they acknowledged its benefits for heart health and diabetes control and prevention, they faulted the Engine 2 dietfor being unnecessarily restrictive and “gimmicky,” and called for more research into some of its claims. “I fail to see anything unique, innovative, or useful with this diet,” one expert said.
- 18. (Tie) South Beach DietAlthough the South Beach Diet earned positive ratings for being able to produce rapid weight loss, its restrictions can make it difficult for dieters to keep the pounds off, experts said. Most were less enthusiastic about its ability to combat diabetes or heart disease.
- 18. (Tie) Vegan DietFlickr:norwichnutsOverall, the health experts were lukewarm on veganism despite giving it fairly high marks as a diabetes or heart disease diet. It is extremely restrictive, doesn’t offer built-in social support, and may not provide enough of some nutrients.
- 22. (Tie) Eco-Atkins DietalamyOne expert summed up Eco-Atkins as a “healthier version of the Atkins diet, but compliance is likely to be more difficult.” That’s because it’s restrictive and little guidance is available.
- 22. (Tie) Glycemic-Index DietalamyExperts were less than impressed with the glycemic-index diet, which distinguishes “good” carbs from “bad.” They scored it particularly low on long-term weight loss, heart benefits, and ease of adherence. Although the diet’s ratings in nutrition and safety were relatively strong, they couldn’t push the diet out of the lower third of the pack.
- 22. (Tie) Zone DietFlickr:Neeta LindThe Zone Diet lagged behind higher-ranked diets, if not always by much, in nearly all ratings categories, including weight loss, how easy it is to follow, and its effect on diabetes and heart health. It’s “unnecessary and tedious to structure every meal around specific macronutrient thresholds,” according to one expert; another stated there is “no magic with the diet.”
- 25. (Tie) Macrobiotic DietalamyExperts gave little credence to the Macrobiotic diet on several counts: Following the plan is a challenge. It’s an extreme change from the standard American diet. And it’s awfully strict. The macrobiotic approach, one expert summed up, is “a mix of sound dietary guidance, mysticism, folklore and nonsense.”
- 25. (Tie) MedifastExperts were likewise unenthused about Medifast. It scored above average in short-term weight loss but was dragged down by lower marks in most other categories.
- 27. Acid Alkaline DietExperts weren’t impressed with the Acid Alkaline Diet, which received mediocre marks in all categories. It performed particularly poorly in areas like overall weight loss and easiness to follow. And don’t expect it to have a positive effect on diabetes or heart disease management or prevention. The diet is “ridiculous and poorly researched,” one expert said. “It’s not based on science.”
- 28. The Fast DietThe widespread concern among experts about the diet’s lack of nutritional guidance on non-fasting days contributed to its poor overall performance. The Fast Diet earned just 2.5 stars, putting it toward the end of the pack, outranking only the raw food, Atkins, Paleo and Dukan diets. “The red flags are no restrictions on non-fast days and no guidance on what constitutes a healthful eating pattern,” one expert said. “This could lead to poor food choices or lack of portion control on non-fast days.”
- 29. (Tie) Atkins DietShutterstockMany of our experts found the popular low-carb Atkins diet leaves much to be desired, at least as an all-purpose diet. Although our expert panel concluded that it could outperform nearly all of its competitors in short-term weight loss, unfavorable marks in other measures — including long-term weight loss, nutrition, safety and heart health — yanked down Atkins in the standings.
- 29. (Tie) Raw Food DietFlickr:timparkinsonThe experts conferred solid marks on the raw food diet for weight loss, both short- and long-term, but considered it all but impossible to follow and its nutritional completeness and safety were concerns. “Doing it well involves considerable commitment and effort, knowledge and sacrifice,” one expert said. “And there are diets that require less of all these that are likely to be just as healthful.”
- 31. (Tie) Dukan DietalamyExperts sent the Dukan diet to the bottom, handing out dismal ratings in nearly every category. Its overall score was more than a full star below average. It’s too restrictive, with lots of rules, and there’s no evidence it works. One expert described the diet as “idiotic.”
- 31. (Tie) Paleo DietalamyExperts took issue with the diet on every measure. Regardless of the goal — weight loss, heart health or finding a diet that’s easy to follow — most experts concluded that it would be better for dieters to look elsewhere. “A true Paleo diet might be a great option: very lean, pure meats, lots of wild plants,” said one expert — quickly adding, however, that duplicating such a regimen in modern times would be difficult.
