Eating a healthy diet is one of the best ways to feel better — physically and mentally. But with so many diets claiming to be the best, choosing the right one can be confusing.

The truth? The best diet is the one you can stick to and that helps you meet your personal health goals. Whether you’re looking for weight loss, heart health, or mental clarity, here’s a breakdown of some popular eating plans.

DASH = Dietary Approaches to Stop Hypertension

Focus: Heart health — by reducing sodium, limiting saturated fat, and promoting whole, plant-based foods.

      Eat more: 

  • Fruits and vegetables
  • Whole grains
  • Lean proteins

      Eat less:

  • Processed and salty foods
  • Fried foods
  • Fatty red meat
  • High-fat dairy
  • Butter
  • Sodium (less than 2,300 mg/day)

      Eat More:

  • Foods with added sugar, sodium, or fat

MyPlate diet icon MyPlate

Focus: Simple, visual guidance based on the U.S. Department of Agriculture’s Dietary Guidelines for Americans.    

Eat More:

  • Fruits and vegetables (at least
    ½ plate)

  • Lean protein (¼ plate)
  • Add low-fat dairy on the side

Eat Less:

  • Processed foods
  • Refined grains
  • High-fat dairy
  • Fatty meats
  • Fried foods

Who benefits: “MyPlate is ideal for simple, general health promotion,” Ventrelle says. “It’s great for school-aged children or individuals new to nutritional changes who may need a simple, practical starting point.”


 

stop watch Intermittent Fasting

Focus: Eating pattern based on time-restricted eating — typically fasting 12 to 16 hours daily. 

Who benefits: Healthy adults seeking structure, weight loss, or reduced late-night eating.

Who should avoid it: ·

  • People under age 18
  • People with a history of eating disorders
  • People who are pregnant or breastfeeding
  • People with type 1 diabetes
  • Anyone with chronic conditions should speak with their medical provider before attempting

 

“Intermittent fasting can support weight loss and metabolic health,” Ventrelle says, “but studies don’t show it outperforms traditional calorie restriction.”
