The 21 Day Fix program has worked wonders for my attitudes about food. The container system has always made sense to me, and I like that I’m not just tracking the quantity of my food…I’m also tracking the quality of my food. You don’t need the containers to measure out your food, though…here are the 21 Day Fix container sizes.
Don’t have the containers yet? You can buy them here.
Green Container = 1 cup
Purple Container = 1 cup
Red Container = 3/4 cup
Yellow Container = 1/2 cup
Blue Container = 1/3 cup
Orange Container = 2 T
You don’t need the containers to measure out your food – you can measure out your portions just like you would with any old measuring device. The benefit to the containers, though, is that it gives you a visual. After a while, you get an idea of how much a serving size is supposed to be (like, really supposed to be, not what your brain is telling you it should be), and the containers aren’t necessary.

That said, I often still use them – I bought a second set to have around the house (which is really helpful if you lose a lid or your kid has stolen them and turned them into bath toys without your knowledge…). But you might not always have the containers with you…and in a pinch, the sizes of the containers should be all you need.

Can you also measure the weight instead of by cup if you're not using the containers? For example, if Purple is 1 C, that's 8oz. So could I use a food scale to measure out 8 oz of fruit? Same for meat, which I believe the weight would be 6 oz for a red container? Can I cook the meat and eat a 6oz piece? I've always wondered this.

You could - but the program is based on the containers so we don't have a clear explanation of what each cup should weigh. For example, applesauce - you get 1/2 a cup of applesauce but it counts as a full purple. And then 1 small apple also counts as a purple. So it's just no as straightforward as measuring by weight all the time.

When making pasta do I measure the pasta dry in the yellow containers? I made pasta last night and measured 2 yellow containers of dry pasta. Cooked it and ate it. But now I’m wondering if I did that wrong and I should have measured the pasta in the yellow container after it was cooked.

In most cases, including pasta, you'll want to measure the food as you eat it. So in this case, use your containers to measure out the cooked pasta! :)
