When it comes to choosing a diet, it can be overwhelming to determine which one is the best for you. However, the annual list of best and worst diets by US News & World Report can provide some guidance. Let's explore the science behind some of the top-ranked diets, discuss their pros and cons, and look at the key takeaways.

Top Diets of 2023: What Diet Plan Best Fits With You?

Featured Diets: Mediterranean, Dash, flexitarian, Mayo Clinic, Mind & Carnivore

The Mediterranean diet has claimed the top spot for the fifth year in a row, It is renowned for its heart-healthy benefits. This diet emphasises consuming fruits, vegetables, whole grains, legumes, lean proteins, and healthy fats like olive oil. The science behind this diet is based on the Mediterranean region's traditional eating patterns and their positive effect on reducing the risk of chronic diseases such as cardiovascular diseases and type 2 diabetes (1). This diet has also been linked to weight loss and improved cognitive function (2).

The DASH (Dietary Approaches to Stop Hypertension) diet focuses on reducing sodium intake whilst encouraging and promoting a diet rich in other minerals including potassium, magnesium and calcium. The DASH diet leans heavily towards the consumption of fruits, vegetables, whole grains, lean proteins, and low-fat dairy products. The diet plans are based on 1600, 2000 or 2600 calories per day. Its scientific basis lies in its ability to lower blood pressure and reduce the risk of hypertension (3). This diet is also associated with weight management and improved overall health (4).

The Flexitarian diet, ranked third, is a flexible, mostly plant-based eating approach that allows for occasional consumption of meat and other animal products. The flexitarian concept was born in the 1990s and has grown increasingly more popular with those wishing to reduce their carbon footprint whilst improving their health. Scientific evidence suggests that adopting a flexitarian diet can lead to weight loss, reduced risk of chronic diseases, and improved overall health (5). This diet focuses on incorporating more plant-based foods while still providing the option to consume animal products in moderation.

Weight Watchers (WW) diet ranked fourth on the list due to its focus on portion control and flexible eating. It promotes a balanced approach to weight loss and weight maintenance by assigning point values to different foods. Scientific studies have shown that this approach can lead to significant weight loss and improved adherence compared to other diets (6).

The Mayo Clinic Diet and the MIND (Mediterranean-DASH Diet Intervention for Neurodegenerative Delay) diet both tied for fifth place. The Mayo Clinic Diet focuses on long-term lifestyle changes and emphasizes consuming whole foods, while the MIND diet combines elements of the Mediterranean and DASH diets, with a specific focus on brain health. These diets are backed by scientific evidence suggesting that they can improve overall health and reduce the risk of chronic diseases (7).

On the other hand, the worst-ranked diet, the carnivore diet, is heavily meat-based and lacks essential nutrients. This diet restricts the consumption of fruits, vegetables, grains, and dairy products, which can lead to nutrient deficiencies and long-term health issues (8). Other poorly rated diets include the Whole30 diet and the GAPS (Gut and Psychology Syndrome) diet, which may lack scientific evidence supporting their effectiveness and long-term sustainability.
