Estimated reading time: 6 minutes

In the past decade, the annual diet rankings from US News & World Report have become a trusted source for evaluating the best diets for overall health. The 2025 rankings featured 35 different diet plans, judged based on several key factors, such as ease of adherence, weight loss potential, nutritional value, safety, and effectiveness in preventing chronic conditions like diabetes and heart disease. Here, we explore the top 10 diets from 2025, along with insights and links to scientific studies and health resources to help you make an informed decision on which diet best suits your lifestyle.

1. Mediterranean Diet

For three consecutive years, the Mediterranean Diet has claimed the top spot. This diet prioritizes fruits, vegetables, nuts, and lean proteins like fish, while minimizing red meat, sugar, and saturated fats. It’s renowned for improving heart and brain health, reducing the risk of chronic diseases, and supporting effective weight management.

A study in The New England Journal of Medicine highlighted the Mediterranean Diet’s role in lowering heart disease and stroke risk (New England Journal of Medicine – Study on Mediterranean Diet).

2. DASH Diet

The DASH (Dietary Approaches to Stop Hypertension) Diet shares second place with the Flexitarian Diet. Specifically designed to lower blood pressure, the DASH Diet emphasizes low-sodium, fiber-rich foods while limiting saturated fats and added sugars. Proven to combat hypertension, it also boosts overall heart health.

The National Institutes of Health (NIH) supports the DASH Diet for its success in reducing high blood pressure (NIH – DASH Eating Plan).

3. Flexitarian Diet

The Flexitarian Diet offers a more flexible approach to vegetarianism, allowing for occasional meat consumption but encouraging a primarily plant-based diet. This diet is linked to a lower risk of heart disease, diabetes, and certain cancers, thanks to its emphasis on fruits, vegetables, and whole grains.

The Academy of Nutrition and Dietetics discusses the health benefits of a plant-based diet, such as a reduced risk of chronic conditions (Academy of Nutrition and Dietetics – What is a Flexitarian Diet).

4. WW (Weight Watchers) Diet

WW (formerly Weight Watchers) uses a point system to help participants monitor their food intake and physical activity levels. This structured approach encourages moderation and long-term weight management by making it easier to stick to healthier eating habits.

Research published in Obesity Reviews found that participants in the WW program lost more weight compared to those receiving standard care (Obesity Reviews – Study on Weight Watchers).

5. MIND Diet

The MIND Diet, which combines elements of the Mediterranean and DASH diets, focuses on enhancing brain health. It encourages the consumption of brain-boosting foods like leafy greens, berries, and nuts and has been shown to reduce the risk of Alzheimer’s disease and cognitive decline.

Research from Rush University Medical Center found that adherence to the MIND Diet can lower Alzheimer’s risk by up to 53% (Rush University Medical Center – MIND Diet and Alzheimer’s).

6. Volumetrics Diet

The Volumetrics Diet is based on the concept of energy density, where foods are categorized by their calorie content per unit of volume. The focus is on low-calorie, high-volume foods that help you feel full without consuming excessive calories. This diet promotes healthy weight loss without feelings of deprivation.

Studies published by the National Center for Biotechnology Information (NCBI) support the effectiveness of low-energy-density foods for weight management (NCBI – Volumetrics Diet Study).

7. TLC Diet

Developed by the National Institutes of Health, the Therapeutic Lifestyle Changes (TLC) Diet aims to reduce cholesterol and promote heart health. It emphasizes high-fiber foods and limits saturated fats, making it effective for lowering cholesterol and improving cardiovascular wellness.

The American Heart Association recommends the TLC Diet for those looking to lower cholesterol through dietary changes (American Heart Association – TLC Diet).

8. Nordic Diet

Inspired by Scandinavian eating habits, the Nordic Diet promotes sustainable, high-quality foods like fatty fish, whole grains, and plant-based foods. It’s recognized for reducing inflammation and supporting heart health.

The World Health Organization (WHO) has endorsed the Nordic Diet for its health benefits and sustainable approach to eating (World Health Organization – Nordic Diet Overview).

9. Ornish Diet

Created by Dr. Dean Ornish, the Ornish Diet emphasizes whole foods, fruits, vegetables, and stress management while limiting high-fat foods, refined carbohydrates, and caffeine. It’s designed to improve cardiovascular health and support a balanced lifestyle.

A study published in The Lancet found that the Ornish Diet, combined with lifestyle changes, can help reverse heart disease (The Lancet – Study on Ornish Diet).

10. Vegetarian Diet

The Vegetarian Diet, particularly the lacto-ovo variety (which allows dairy and eggs), includes plant-based foods and has been linked to improved heart health and a reduced risk of chronic diseases. With numerous variations, it offers essential nutrients and promotes overall wellness.

The Harvard T.H. Chan School of Public Health highlights the benefits of a vegetarian diet, including lower risks of heart disease and type 2 diabetes (Harvard T.H. Chan School of Public Health – Vegetarian Diet Review).

These top diets not only offer a variety of nutritional benefits but also show great potential for improving health and preventing chronic diseases. Each diet plan brings unique features that can align with different health goals and lifestyles. The key to success is choosing the diet that fits your personal health needs and is sustainable in the long term.
