Best And Worst Diets Of 2024: Top 10 Ranked By U.S. News

The annual U.S. News & World Report diet rankings for 2024 highlight evidence-based eating patterns that promote long-term health, sustainability, and ease of adherence. For the seventh consecutive year, the Mediterranean diet claims the top spot overall, praised by a panel of 43 experts including nutritionists, physicians, and dietary consultants for its comprehensive benefits. This ranking evaluates 30 popular diets across 14 categories, focusing on nutritional completeness, safety, long-term weight loss potential, and disease prevention.

Why the Mediterranean Diet Reigns Supreme

The Mediterranean diet emphasizes whole, nutrient-dense foods like fruits, vegetables, whole grains, legumes, nuts, seeds, olive oil, fish, and moderate lean proteins. It avoids processed foods, added sugars, and excessive red meat, fostering heart health, diabetes management, and overall wellness. Experts laud its flexibility, cultural appeal, and robust scientific backing from long-term studies like the PREDIMED trial, which links it to reduced cardiovascular risk.

In 2024, it dominated multiple categories:

• Best Diet Overall: #1
• Best Diets for Diabetes: #1
• Best Heart-Healthy Diets: #1
• Easiest Diets to Follow: #1
• Best Diets for Bone and Joint Health: #1
• Best Family-Friendly Diets: #1
• Best Diets for Healthy Eating: #1

Its runner-up, the DASH diet (Dietary Approaches to Stop Hypertension), focuses on lowering blood pressure through vegetables, fruits, low-fat dairy, whole grains, lean proteins, and nuts while limiting sodium. Developed by the National Institutes of Health, DASH ranks #2 overall and excels in heart health and hypertension management.

Top Diets Overall: Full Breakdown

U.S. News evaluated diets on criteria like nutritional balance, evidence from clinical trials, and real-world applicability. Here’s the top 10 for Best Diets Overall in 2024:

These diets prioritize whole foods, variety, and sustainability over restrictive rules.

Category-Specific Winners

Best Diets for Diabetes

Mediterranean leads, followed by low-carb plans like Vegan and Vegetarian, which stabilize blood sugar through fiber-rich foods. Keto ranks lower due to limited long-term data.

Best Heart-Healthy Diets

Mediterranean and DASH tie for dominance, supported by NIH research showing 20-30% reductions in cardiovascular events.

Best Weight-Loss Diets

WW and Volumetrics top this list for sustainable calorie control without extreme restriction.

Easiest Diets to Follow

Mediterranean’s delicious, flexible nature makes it #1; no calorie counting required.

Best Diets for Families

Mediterranean again, for kid-friendly meals emphasizing shared, flavorful eating.

Best for Bone and Joint Health

Anti-inflammatory foods in Mediterranean combat osteoporosis and arthritis.

Other notables include Best Plant-Based (Mediterranean-Vegetarian hybrid) and Best Fast Weight Loss (where more aggressive plans like Atkins briefly shine but falter long-term).

The Worst Diets of 2024: What to Avoid

Bottom-ranked diets often lack nutritional balance, rely on unsustainable restrictions, or ignore scientific evidence. Keto (#25) and Atkins (#26) promote high-fat, low-carb eating but risk nutrient gaps, heart strain, and yo-yo weight cycling.

The absolute worst:

• #30: Raw Food Diet – Claims cooking destroys nutrients, but evidence shows cooking enhances bioavailability of lycopene and beta-carotene. Risks foodborne illness and deficiencies in B12, iron.
• #29: Hollywood Diet – Extreme juice fasts lead to muscle loss, fatigue.
• #28: Keto – Short-term weight loss but high dropout due to side effects like ‘keto flu’.
• #27: Atkins – Similar carb phobia limits plant foods.

These score low on safety, completeness, and adherence.
