The 21 Day Fix is a popular nutrition and fitness program that focuses on portion control, clean eating, and consistent exercise. In just three weeks, it can help you build healthier eating habits, lose weight, and feel more energized.

While the concept is simple, actually following the plan day after day can be tricky without a clear guide and a way to track your progress. This is where the MyFitnessCoach App makes a big difference.

In this article, you’ll learn exactly what the 21 Day Fix Meal Plan is, how to follow it, and how to make it easier and more effective with MyFitnessCoach’s Food Logger and Custom Diet Plan features.


What is the 21 Day Fix Meal Plan?

The 21 Day Fix focuses on portion control using a color-coded container system. Each container represents a food group and a specific portion size:

  • Green: Vegetables
  • Purple: Fruits
  • Red: Proteins
  • Yellow: Carbohydrates
  • Blue: Healthy fats
  • Orange: Seeds and dressings

The number of containers you use per day depends on your calorie target, which is based on your weight and activity level.

The key is to eat balanced meals from the correct number of containers each day, no calorie counting required.


Benefits of the 21 Day Fix Meal Plan

  • Portion Awareness: Learn how much food your body actually needs.
  • Balanced Nutrition: Encourages a variety of whole, unprocessed foods.
  • Sustainable Results: Builds healthy habits you can maintain after 21 days.
  • Customizable: Fits different dietary needs and preferences.

Why the MyFitnessCoach App Makes the 21 Day Fix Easier

The container system is a great visual tool, but it can still be hard to remember exactly how many containers you’ve used in a day, especially when life gets busy. That’s where the MyFitnessCoach App helps.

With MyFitnessCoach, you can:

  • Log Each Meal: Track your container servings or log calories and macros.
  • Follow a Pre-Made Plan: Use ready-to-go 21 Day Fix-inspired menus.
  • Get Shopping Lists: Automatically generate lists based on your meal plan.
  • Track Your Progress: See how your eating habits improve over time.

Instead of guessing, you’ll have a clear picture of your daily intake right on your phone.
