For those with busy schedules, it is always easier to opt for grab-and-go meals or fast food. It saves the time of having to cook and buy groceries every day. However, doing this is not always the healthiest, or even if it is, it can be quite expensive. Eating home-cooked meals is the best way to save money and eat healthily, but the only problem is the amount of time spent. Here’s how to meal prep to help you save money and time.

You only need to spend a day to prep for the entire week. In this article, let’s explore what meal prep is in this beginner’s guide, how you can meal prep for weight loss, and if it’s safe to prep for a longer period of time.

Key Takeaways

  • Meal prep is a way of preparing and storing a large portion of food in advance.
  • It’s a good way to save money, and eat healthier without stressing about what to eat and avoiding unhealthy fast food or takeouts.
  • To meal prep for weight loss, you need to first know your daily calorie and macronutrient requirement. From there, you can plan out your meals and prepare your shopping list for the days or weeks of meal planning.
  • You can also find some easy recipes to meal prep in this article.

Meal prep is the practice of preparing and storing a large portion of full meals or snacks in advance so that you can easily heat and enjoy them throughout the week or even longer.

Why Should You Meal Prep?

It’s a great strategy for anyone looking for convenience, to save money, or for those trying to eat healthier without the stress of what to eat or having to rely on takeouts that often lack balanced nutrition, including healthy fats.

Preparing your meals gives you full control over the ingredients, portions, and nutrition in each meal. If you have a specific health goal to lose weight, gain weight, or gain muscle, it makes it much easier for you to stay aligned with it.

A study suggests that the meals consumed outside in restaurants tend not to provide the essential nutrients that your body needs [1]. It’s estimated that less than 0.1% of consumed foods from full-service restaurants and fast-food restaurants meet the ideal nutrition quality. This meant that the foods either did not contain a variety of fresh fruits and vegetables, whole grains, lean meat, fish and seafood, or nuts.

Meals by large chain restaurants in the U.S. were often found to be high in calories, sodium, saturated fat, and sugar.

Main benefits of meal prepping:

  • Helps to save time
  • Helps to save money
  • Prevents food waste
  • Plays a role in weight control
  • Allows you to create nutritionally balanced meals
  • Reduces stress and decision fatigue on what to eat

How to Start a Meal Prep: What to Know

There are a few different ways to go about meal prepping for the first time. What we recommend is for you to start small and simple.

Step 1: Choose your meal prep style

The first step is to choose how you want to meal prep. Is it making a big batch of food at once so that you can freeze and reheat, is it portioning out multiple meals into containers, or is it only prepping ingredients for faster cooking later?

Step 2: Plan your meals and timings

Once you have an idea of how you want to meal prep, then it’s time to think about whether you will be preparing for breakfast, lunch, or dinner or for all the meal timings.

Step 3: Set aside a prep day

From there, choose a day of the week to set aside for planning the food menu, creating a grocery list, and grocery shopping for all the ingredients, followed by the actual food prep. If you aren’t sure what to make, you can use the meal plan feature in the Eato app for some quick inspiration.

Step 4: Be efficient during prep

On prep day, you want to see how you can make the process more efficient by multitasking. Perhaps while waiting for an ingredient to boil, you can chop up vegetables or fruits. Also, you want to consider focusing on foods that take a long time to cook first.

Step 5: Store your meals properly

After all your ingredients or food have been prepped, you can proceed to store them in airtight food containers to be kept in the freezer. Anytime you want to consume it, you only need to defrost and reheat it for consumption.

How to Meal Prep for Weight Loss?

Meal preparation for weight reduction follows the same methods as in the previous section. However, the primary distinction is that you must pay careful attention to your calorie and macronutrient requirements.

To help you out, here’s a short guide on how to meal prep for weight loss:

Calculate your daily calorie and macronutrient needs

Create a balanced and nutritious meal plan

How to Meal Prep for the Week Ahead?

Preparing your meals for the week ahead typically involves a lot of organizing, shopping, and prep time.

The planning part is usually the most tedious process because it involves you having to know what your schedule will be like for the week or month, so you can determine how much and how often to prepare your meals.

After doing so, you will still need to create a proper food menu for each day of the meal plan, and come up with a shopping list based on it. Only then can you do the shopping, start preparing, and store your meals ahead of time.

Is it safe to meal prep for 7 days?

In general, if you are handling and cooking your ingredients properly, they should be good and safe to last for 4 days. This is assuming you plan on storing your food in airtight, meal prep containers inside the fridge.

If you are meal prepping for 7 days or longer and want it to last, you should cook and store them properly in the freezer. Freezing your food will stop the growth and reproduction of bacteria throughout the time it’s frozen.

Just so you know, bacterial growth starts the moment that your food begins to cool towards room temperature.
