6 Things the World’s Most Successful Diets Have in Common

  • Low in Added Sugar: Added sugar is one of the unhealthiest aspects of the modern diet. What’s more, sugar provides empty calories, as it supplies many calories but virtually no essential nutrients. There is universal agreement that a high intake of added sugar is unhealthy, and most successful diets recommend limiting it.
  • Eliminate Refined Carbs: Refined carbs — which are sugar and processed starchy foods, including grains, that have had most of the fiber removed — are another ingredient that nutrition experts agree is unhealthy. All successful diets eliminate refined grains like wheat flour, while some diets like paleo and low-carb ban grains altogether.
  • Avoid Vegetable Oils High in Omega-6 Fat: Many diets encourage lower intake of omega-6-rich vegetable oils like soybean or canola oils. Still, it remains unknown whether or not these oils are harmful.
  • Eliminate Artificial Trans Fats: Trans fats are made by hydrogenating vegetable oils. Many studies show a link to inflammation and conditions like heart disease. Its use has been limited or banned in many countries, including the United States.
  • High in Vegetables and Fiber: All successful diets emphasize eating plenty of vegetables and — in most cases — fruit. These foods are high in antioxidants and healthy prebiotic fibers.
  • Focus on Foods Instead of Calories: Most successful diets emphasize a lifestyle change that includes whole foods — and let weight loss follow as a natural side effect.
