Meal prep pricing and portion sizes confuse most customers because there's no industry standard—different prep services use different baseline amounts, and costs vary wildly by location and protein type. Understanding what a "standard serving" actually means for your budget and goals helps you compare offers fairly and avoid overpaying for portions you don't need. This guide breaks down realistic portion sizes, typical pricing structures, and what to expect when hiring a meal prep service.
What Counts as a Standard Serving?
A standard protein serving is 3–4 ounces (85–113 grams) cooked weight for most meal prep services. A grain or carb serving is typically ½ to ¾ cup cooked. Vegetables usually fill half your container—roughly 1.5 to 2 cups raw or cooked, depending on the vegetable type.
Many prep services package meals in 800–1,200 calorie ranges, with 5–7 meals per week as the minimum order. If you're buying individual meals rather than full-week packages, expect portions to follow the protein-carb-vegetable breakdown above, though portion sizes shift slightly based on dietary goals (higher protein for strength work, more carbs for athletes).
The key: ask prospective services to specify their exact portions in ounces or grams, not just "one serving." This prevents disappointment when your food arrives.
Typical Price Ranges by Service Level
Budget meal prep ($8–$12 per meal) usually features basic proteins like chicken breast, ground turkey, or budget cuts of beef. Rice, pasta, and seasonal vegetables fill the rest. These services operate at volume and use less premium ingredients.
Mid-range services ($12–$18 per meal) offer more protein variety—salmon, grass-fed beef, organic chicken, plant-based options. Grains might include quinoa or wild rice. Sauces and seasoning are more developed.
Premium meal prep ($18–$28+ per meal) provides high-quality proteins (grass-fed, wild-caught, pasture-raised), organic vegetables, and thoughtful flavor combinations. Some include macro customization or specific diet accommodations (keto, paleo, low-FODMAP).
Factor in delivery fees ($5–$15 per order, sometimes waived for minimums) and whether the service offers week-to-week flexibility or requires multi-week commitments upfront.
How to Compare Pricing Fairly
When shopping around, use a cost-per-serving metric rather than just total price. A $120 package of 8 meals is $15 per meal; a $90 package of 4 meals is $22.50 per meal. The first looks cheaper but might use smaller portions or lower-quality ingredients.
Check whether pricing changes seasonally. Winter vegetables often cost less; fresh berries spike in price December through February. Reliable services should clearly communicate price adjustments.
Look at protein quality and sourcing. "Antibiotic-free chicken" and "grass-fed beef" justify higher prices. If sourcing isn't mentioned, that's worth asking about directly.
When comparing options, platforms like Mercoly let you browse local and regional meal prep services side-by-side, review customer feedback, and see exact pricing breakdowns before you commit.
Portion Sizing for Different Goals
Weight loss: 700–900 calories per meal, 25+ grams protein, higher vegetable ratio (60% of plate). Budget $12–$16 per meal.
Maintenance: 1,000–1,200 calories, 30–35 grams protein, balanced carbs and fats. Mid-range ($14–$18) services handle this well.
Muscle gain: 1,200–1,500 calories, 35–45 grams protein, emphasis on rice or potatoes. Premium services ($18–$22) often customize for this.
Plant-based: Portions may shift toward larger volumes of legumes and grains to hit protein targets. Budget 10–15% more than comparable omnivore meals due to ingredient sourcing.
Red Flags When Choosing a Service
If a service won't specify portion sizes, walk away. Vague language like "generous" or "filling" means inconsistency.
Meals sitting in your fridge longer than 4 days indicate poor freshness standards or overcommitted portion sizes. Confirm storage guidelines and delivery schedules upfront.
Avoid services that refuse modifications. Even budget providers should accommodate basic swaps (brown rice instead of white, extra broccoli).
Frequently Asked Questions
Q: Can I mix portion sizes in a single week's order? Most services allow this at no extra charge—you might want 4 meals at 900 calories and 2 at 1,200 calories. Confirm flexibility before ordering; some require all meals to match.
Q: Do portion sizes shrink after cooking? Yes. Protein shrinks 20–25%, grains roughly 10–15% by weight. Services should quote cooked weights, but ask directly to be sure.
Q: What's the minimum commitment most services require? Weekly subscriptions are standard, with cancellation anytime. Some charge a 2–4 meal minimum per week; others let you pause for a week without penalty.
Start by comparing 3–5 local services in your area, confirm their portion specs match your goals, and try a single week before committing longer.
