Frequently Asked Questions
How long does meal prep food last?
Most cooked meal prep lasts 3-5 days in the refrigerator. For a full week, freeze meals for days 4-7 and thaw overnight.
Should all meals have the same calories?
Not necessarily. Many people prefer a larger lunch and lighter breakfast. The key is that the total for the day matches your target.
What containers work best?
Glass containers are microwaveable and do not stain. Look for airtight, leak-proof options. Divided containers help keep foods separate.
