Prepping Too Much at Once

• Mistake: Making a full week’s worth of meals, only to get bored or have food go bad before you can eat it.
• Fix: Instead of prepping seven days’ worth of meals, aim for 3–4 days at a time. You can also freeze portions to keep them fresh and prevent waste.
• Why This Happens: Many people start meal prepping with the intention of saving prep time, but over-prepping can lead to food fatigue, making it harder to stick with the habit.

Pro Tip: Store prepped meals in portions rather than large batches. That way, you can pull out just what you need and reduce spoilage.

Not Planning Before You Shop

• Mistake: Going to the grocery store without a plan and buying random ingredients that don’t work well together.
• Fix: Take a few minutes to create a meal plan and grocery list. Check what you already have at home to avoid buying unnecessary items.
• Why This Happens: Lack of planning leads to impulse buying, which can result in wasted ingredients or unhealthy last-minute choices.

Pro Tip: Plan meals around ingredients that can be used multiple ways. For example, grilled chicken can be used in salads, wraps, or grain bowls throughout the entire week.

Choosing the Wrong Meal Prep Containers

• Mistake: Using low-quality or mismatched containers that leak, don’t seal properly, or aren’t the right size.
• Fix: Invest in high-quality, airtight containers—glass containers or BPA-free plastic options work best. Use portioned or individual containers for easy grab-and-go meals.
• Why This Happens: Many people use whatever containers they have, but poor storage leads to food spoilage, spills, and difficulty reheating meals.

Pro Tip: Use stackable, clear containers to make it easy to see what you have prepped. Divide meals into single portions for better portion control.

Prepping Meals That Don’t Stay Fresh

• Mistake: Making meals that get soggy or spoil quickly, leaving you with unappetizing food midweek.
• Fix: Choose foods that store well, like roasted vegetables, grilled proteins, and hearty whole grains. Keep dressings and sauces separate until serving.
• Why This Happens: Some foods, like salads or crispy vegetables, don’t hold up well when stored in the fridge for several days.

Pro Tip: If prepping healthy salads, layer ingredients in a jar—heavier ingredients on the bottom, delicate greens on top—to keep everything fresh until you’re ready to eat.

Ignoring Variety (Eating the Same Thing All Week)

• Mistake: Meal prepping just one or two meals and getting tired of eating the same thing repeatedly.
• Fix: Use mix-and-match ingredients—prep proteins, carbs, and veggies separately so you can create different types of food throughout the week.
• Why This Happens: It’s easy to fall into a routine, but lack of variety can make meal prep feel like a chore.

Pro Tip: Season proteins and vegetables differently. For example, cook chicken breast in three ways—one with garlic and herbs, another with barbecue sauce, and a third with a spicy marinade. Check out my post on the 5 best Marinades for Chicken for some seasoning inspiration!

Not Accounting for Macros or Portions

• Mistake: Prepping meals without considering protein, carbs, and fats, which can throw off your nutrition goals.
• Fix: Ensure each meal has a good balance of lean protein, fiber, and healthy fats to keep you satisfied and energized.
• Why This Happens: Many people focus on convenience rather than balanced nutrition, which can lead to energy crashes or overeating.

Pro Tip: A good rule of thumb is to fill half your plate with veggies, one-quarter with protein, and one-quarter with complex carbs for a balanced meal. Investing in a good food scale can be helpful as well in tracking the correct portions for your body.

Skipping Snacks & Breakfast

• Mistake: Only prepping lunch and dinner, then grabbing unhealthy snacks when hunger strikes.
• Fix: Include healthy snacks like protein balls, yogurt cups, or hard-boiled eggs. Prep easy breakfasts such as overnight oats or egg muffins.
• Why This Happens: People often forget about snacks and breakfast, which leads to unplanned, less nutritious choices.

Pro Tip: Make snack packs with nuts, fruit, and protein bars so you always have a healthy option on hand.

Not Using Time-Saving Shortcuts

• Mistake: Trying to cook everything from scratch, making meal prep take way too long.
• Fix: Use pre-cooked proteins like rotisserie chicken, pre-chopped veggies, frozen grains, or instant pot meals to speed up the process.
• Why This Happens: Some people think meal prep has to be complicated, but shortcuts make it more sustainable.

Pro Tip: Designate specific prep days to streamline your meal prep routine and save time in the kitchen.

Forgetting to Label & Date Meals

• Mistake: Storing meals without labeling them, leading to confusion about when they were made.
• Fix: Label each container with the prep date. Store meals properly—keep some in the fridge and freeze others for later use.
• Why This Happens: It’s easy to forget when meals were prepped, which increases the risk of food waste.

Pro Tip: Use freezer-safe labels and organize meals by day to ensure you eat them in the right order.

Not Having a Backup Plan

• Mistake: Life happens, and unexpected events can throw off your meal prep plan, leading to ordering takeout.
• Fix: Keep a few backup meals in the freezer or have quick-assemble meal options, like canned tuna, fresh produce, frozen veggies, or whole-grain wraps, for busy days.
• Why This Happens: When plans change, it’s easy to fall back on unhealthy choices without a backup plan.

Pro Tip: Keep emergency meals portioned and ready to go in the freezer for stress-free dinners.

Avoiding these common meal prep mistakes will help you save time, reduce waste, and keep your healthy meals fresh and exciting. Start small by improving one or two areas at a time, and soon, you’ll have a meal prep system that works for you.
