What is the size of the red container used in the 21 Day Fix program?

The red container in the 21 Day Fix program is designated for proteins and has a size of 3/4 cup, which is approximately equivalent to 6 ounces. The entire program by Autumn Calabrese utilizes a color-coded container system to help participants manage portion sizes and dietary balance, with each color representing a different type of food. This simple and effective portion-control approach ensures individuals consume an appropriately sized portion of various food groups as part of their meal plan throughout the 21-day duration of the program.
