Which Is the Best Meal Prep Container for Weight-Loss? – My Top 6 Options

1. Glad 25-Ounce Containers

The Glad containers always come as a set of five boxes. They are medium and small-sized, and they are perfect for salads and soups. If you want to lose weight or you’re following a diet plan and are trying hard to consume smaller meals, these 25-ounce containers are great for your needs.

What I like most about them is the fact that they are significantly deeper than other lunch boxes. Therefore, you can easily store your soups in them. I’ve listed some other characteristics that describe the Glad meal prep containers, below:


  • The containers come with leak-proof lids that also have a tight seal type of lock
  • Not only are these food holders very affordable, but they are also safe to place in the freezer. Moreover, you can conveniently heat your meals in the microwave directly in these containers and then, clean them in the dishwasher
  • The lids are so strong that you won’t have to worry about spills. They remain closed even when you invert them
  • The plastic is free from BPA, so these containers are safely reusable

Despite all the above advantages, a few reviewers expressed their disappointment, saying these containers are not completely dishwasher-safe. One consumer even stated that the ones she bought began to leak shortly after she started using them.


Like I mentioned above, the Glad 25-Ounce Containers are surprisingly affordable. One pack of five counts is sold for the price of approximately $4.

4. 3-Compartment Meal Prep Containers by Simple Houseware

As the name says it, these containers have three compartments each. Therefore, I consider them a wonderful solution for when you want to measure the portion size of each main nutrient and to keep a balance and a good ratio between proteins, vegetables, and carbohydrates.

Each container has 36 ounces, so they are large enough to store healthy yet bigger foods such as salads.


Some of the main characteristics of Simple Houseware meal prep containers are the ones listed below:

  • The plastic is BPA-free, so these vessels are safe to use
  • They keep the ingredients separated, and the foods won’t leak from one section to another

5. Silicone Food Storage Containers by Collapse-It

These containers are made from silicone and you can place them in the microwave or the oven with their lids on (the only thing you must remember is to open the small cap placed in the middle of the lid for proper ventilation which leads to an efficient reheating).

The fact that they have a collapsible feature makes them easier to store. These types of food containers come in handy, especially when you have a tiny kitchen and not enough storage space.


Here are the things that differentiate the Collapse-It containers from other similar products:

  • The classic package comes with four different rectangle pieces of different sizes
  • You can also choose to buy the set that has round containers
  • The entire set is collapsible which means, when you’re not using it, the containers will fold to half their initial sizes
  • You can easily store the set in your kitchen
  • The boxes are safe to use or place in the freezer, oven, and microwave. Moreover, they have a sealed vacuum feature, and they are very durable
  • The materials are BPA-free, and each of the container’s color will help you control your nutrient portions – each color is assigned to a certain type of food: veggies, carbs, protein, etc.
  • The vented seal on top of the lid is leak-proof, and the entire pack is compact and easy to use. All these characteristics make the Collapse-It set the perfect choice for work lunchboxes

The majority of reviews are positive, and most consumers simply love this meal prep storage set. However, a few people said these containers are not as sturdy as one would expect, especially when they are full.


As I said, you can either purchase the set of rectangle pieces, or you can opt for the round containers. Either way, you will have to pay $39.99 for all four pieces of the Collapse-It Container Set. These boxes are more expensive than many other similar food storage products.

6. Pyrex Storage Container Set

This set contains no less than 20 different pieces. Clients can use the boxes’ colorful lids to their advantage. What I mean is they can assign each color to a certain food. For instance, one could store meat in green containers and salads in red containers.

With these boxes, you will become more organized than you’ve ever been. Pyrex vessels are made from durable glass, and they are safe to use in the oven or the microwave. Moreover, they are very easy to clean.


Here are some more things you should know about this set that will help you make a more informed purchasing decision:

  • This food storage set is a highly versatile one. I simply love their variety when it comes to sizes, lid colors, etc. You can safely use these glass container multiple times a day without having to worry about harmful chemicals that plastic containers might have
  • They are durable and dishwasher-safe, and you can use them to control your portions
  • Glass containers are a good idea when you have a lot of leftovers. Leftover foods seem to last longer in glass boxes than in plastic containers
  • Although they aren’t collapsible, the Pyrex vessels are easy to store, and they don’t occupy a lot of space in your kitchen

I must confess I haven’t used these containers myself, but I did find several reviews from people who were rather disappointed with the Pyrex meal prep set. According to them, the lids of the containers don’t always create a tight seal. In fact, it appears that this lid-related issue only occurs with the blue lids.


The Pyrex Container Set costs between $48.50 and $54.89, depending on the seller.

What to Look for When Buying the Best Meal Prep Containers for Dieting

Choose Air-Tight and Leak-Proof Lids

When you are buying a food storage container set, make sure the lids are leak-proof and have an air-tight seal feature. After all, nobody wants to find out that their food created a whole mess inside their lunch bag. It’s true, however, that certain types of lids are better than others. There are a couple of tricks you can do to test the quality of the lids:

  • Place a small amount of liquid inside the container, then close the lid. After that, lean the box on one side to see whether or not the liquid will seep out
  • With the lid closed, shake the container for an entire minute to test the durability of the lid
  • Drop the closed container on the kitchen counter to see if the lid stays on or if the box cracks

Buy Microwave-Resistant and Dishwasher-Safe Containers

Although, in my opinion, the best types of containers are those made from glass, you can also opt for plastic food boxes but make sure they are BPA-free which means that they don’t contain harmful chemicals that might mix with your food, especially when you heat them up.

Other Important Aspects to Consider

  • Buy only freezer-friendly containers that will preserve your meals for a longer time
  • Choose those products that are also convenient, easy to use, and easy to clean. I will let you in on a little secret in terms of ease of cleaning; the best meal prep containers are those made from either glass or stainless steel
  • Select containers that are portable so that you can use them on the go
  • Be aware of those brands that advertise their products as being extraordinary and claiming some unrealistic things. If you have never used food containers before, I recommend you start with a standard set and then, go from there

Below, I have created a brief comparative overview to see what differentiates glass containers from plastic food boxes:

Glass Food Containers

Plastic Food Containers

Easier to clean and safer to use

Are lightweight which makes them the perfect option for an active lifestyle

Free from harmful chemicals

They come in various sizes which makes them highly convenient

Are pricier yet economical in the long run due to their durability

Plastic containers are easily disposable, and they cost less than glass containers

Can be a bit heavy to carry around if you’re always on the road

Some plastic materials might contain dangerous compounds
