One Meal, Three Portions: A Visual Guide to Portion Sizes

Portion size can make or break your calorie goals. 🍽️

You might eat the same meal as someone else — but not the same amount. And while the ingredients may be healthy, too much of anything can sabotage your progress.

That’s why we created “One Meal, Three Portions,” a visual breakdown showing how a single meal can drastically change in calories depending on the portion size.

🍽️ What Is “One Meal, Three Portions”?

It’s a visual method that shows you the calorie differences between:

  • 🍽️ Undereating (too little)
  • 🍽️ Ideal serving (just right)
  • 🍽️ Overeating (too much)

We analyzed dozens of common meals using photo logging and verified nutrition data from NutriSnap to help you learn what proper portioning really looks like.


📊 Visual Example: Chicken Bowl Breakdown

🥄 Portion A – Light Meal (approx. 350 cal)

  • 3 oz grilled chicken
  • ¼ cup cooked rice
  • ½ cup broccoli
  • Light drizzle olive oil

🍴 Portion B – Balanced Meal (approx. 500 cal)

  • 4 oz grilled chicken
  • ½ cup cooked rice
  • 1 cup broccoli
  • 1 tbsp olive oil

🍽️ Portion C – Large Meal (approx. 750 cal)

  • 6 oz grilled chicken
  • 1 cup cooked rice
  • 1.5 cups broccoli
  • 2 tbsp olive oil

Same ingredients. Very different calorie totals.


🤔 Why Portion Awareness Matters

  • Healthy food ≠ low calorie if the portion is too large
  • Overeating by just 200–300 calories per day can prevent fat loss or lead to gain
  • Undereating may leave you fatigued, under-fueled, or lead to bingeing later

When you learn to eyeball portion sizes visually, you’ll feel more confident eating at home, dining out, or prepping meals.
