Problem

Most readers arrive here because How to Count Calories Without an App sounds useful, but the next step is not obvious. The real problem is deciding whether this idea, app, tactic, or workflow is worth time, budget, and operational attention before it turns into another half-used tool.

Why it matters

In calorie tracking, weak decisions compound quietly. A vague comparison, a rushed setup, or an app chosen because it looked popular can create extra cost, slower execution, and messy reporting later. The point of this guide is to turn the topic into a practical decision instead of another open browser tab.

How to start

Start by writing down the outcome you want, the constraint that matters most, and the first metric you will check after implementation. Then use the sections below to compare options, avoid the common traps, and pick the smallest next action that produces evidence.

The best way to count calories without an app is to combine three tools: a verified food database (USDA FoodData Central), measuring equipment (kitchen scale, cups, spoons), and a structured tracking method (notebook or spreadsheet). Calculate your Total Daily Energy Expenditure (TDEE), look up calorie values for every food you eat, weigh your portions, and log everything in a journal. Manual tracking takes 15–30 minutes per day and builds strong nutrition awareness that lasts a lifetime. Yes, counting calories helps with weight management — research consistently shows that people who track their intake lose roughly twice as much weight as those who do not, regardless of whether they use an app or a pen.

In a hurry? Start tracking with our Calorie app — it replaces your notebook, calculator, and food database with one tap. Most users log their first meal in under 60 seconds.


Quick-Start Guide: How to Count Calories Without an App Today

If you want to start counting calories manually right now, follow these five steps. The entire setup takes under 30 minutes.

  1. Calculate your TDEE — Use the free Harris-Benedict formula below or search “TDEE calculator” online. This gives you a daily calorie target.
  2. Grab a notebook or open a spreadsheet — Create columns for Date, Meal, Food, Portion, Calories, and Running Total.
  3. Weigh or measure your food — Use a kitchen scale for solids ($15–30) and measuring cups for liquids ($5–10).
  4. Look up calorie values — Check nutrition labels, USDA FoodData Central (fdc.nal.usda.gov), or restaurant nutrition guides.
  5. Log everything immediately after eating — Do not wait. Memory fades within hours.

That is it. You are now counting calories without an app. The sections below go deeper into each step, but this quick-start guide is enough to begin today.


Why Count Calories Without an App?

Manual calorie counting teaches skills that no app can fully replace. When you look up every food, weigh every portion, and tally every meal by hand, you develop an intuitive sense of calorie density that lasts a lifetime.

Research in the International Journal of Obesity shows that people who track calories — by any method — lose roughly twice as much weight as those who do not track. The method matters less than the habit.

That said, manual tracking demands more time and discipline than using a calorie app. This guide teaches the manual method thoroughly, then explains when and why switching to an app-based approach makes sense for long-term sustainability.


Can Counting Calories Help With Weight Management?

Yes. Calorie counting is one of the most evidence-based strategies for both losing weight and maintaining weight loss long term. Here is what the research shows:

Weight Loss and Body Composition

A meta-analysis in Obesity Reviews found that self-monitoring of food intake doubled weight-loss success rates compared to no tracking. The effect held true for both manual and digital methods. The mechanism is straightforward: tracking creates awareness, awareness drives better decisions, and better decisions produce a calorie deficit that leads to weight loss.

Improved Nutrition Knowledge

People who track calories for 8+ weeks develop significantly better portion estimation and food-label reading skills, according to research in the Journal of the Academy of Nutrition and Dietetics. This knowledge persists even after you stop tracking.

Behavioral Awareness

Writing down everything you eat creates a mindfulness effect that reduces impulsive snacking. A study in Appetite found that participants who kept food journals consumed 15–25% fewer calories than untracked controls — even without being told to change their diet.

Long-Term Weight Maintenance

The National Weight Control Registry reports that 74% of successful long-term weight maintainers used some form of calorie or food tracking during their weight-loss phase. The tracking habit itself, not the specific tool, predicted success.

Low Cost

Manual calorie counting requires only a notebook and pen. A kitchen scale is optional but recommended. Total startup cost: $0–30, compared to $5–15/month for most calorie app subscriptions.


The Psychological Benefits of Manual Tracking

Manual calorie counting offers psychological advantages that digital tracking often overlooks. Physically writing down each meal activates deeper cognitive processing than tapping a screen, which increases dietary self-awareness and accountability.

Research published in Appetite found that pen-and-paper food journaling produced higher levels of dietary self-awareness than app-based logging in a controlled comparison. Participants who wrote their intake by hand were more likely to notice patterns between their eating habits, mood, and energy levels.

Key Psychological Advantages

  • Slower, more deliberate logging — Writing forces you to pause and think about each food choice, reducing mindless eating.
  • Stronger habit formation — The physical ritual of opening a notebook and writing reinforces the tracking habit more than tapping an app icon.
  • Pattern recognition — Over weeks, your handwritten log reveals trends in hunger, cravings, and emotional eating that automated dashboards often miss.
  • Sense of ownership — The effort invested in manual tracking creates a psychological commitment to the process, making you less likely to abandon it casually.

These benefits make the first 2–4 weeks of manual tracking especially valuable, even if you later transition to a calorie app for convenience.


Tips for Beginners

Starting a calorie-counting habit can feel overwhelming. These beginner tips help you avoid common pitfalls and build momentum during the critical first two weeks.

Start Simple

Do not try to track every micronutrient on day one. Focus exclusively on total calories for the first week. Add protein tracking in week two, and macronutrients only after you feel comfortable.

Track Before You Eat

Log your planned meal before eating it. This “pre-logging” strategy helps you make better portion decisions and prevents post-meal regret. It also reduces the temptation to “forget” inconvenient calories.

Build a Go-To Meal List

Write down 5–10 meals you eat regularly with their calorie values. Having this personal reference card eliminates the need to look up the same foods repeatedly, cutting daily tracking time in half.

Expect Inaccuracy at First

Beginners typically underestimate calorie intake by 20–30%. This is normal and improves with practice. Focus on consistency, not perfection. Even an imperfect calorie log produces better results than no log at all.

Use the 80/20 Rule

Track precisely during weekdays and allow estimates on weekends. One imperfect day does not erase a good week. If you miss a day, resume immediately — do not wait for Monday.

Set a Minimum Tracking Streak

Aim for 21 consecutive days. Research shows this is enough time to establish a habitual behavior. After three weeks, tracking starts to feel automatic rather than burdensome.


Common Challenges Faced When Manually Counting Calories

As helpful as manual tracking can be, it has its challenges. Here are some common hurdles and how to navigate them:

Inconsistent Logging

Many find it easy to skip entries when busy. To combat this, set reminders or have your tracking tools accessible at all times.

Time Commitment

While manually counting calories may take more time than an app, building a personal food database can significantly reduce logging time in the long run. Consider dedicating time to this foundation early on.

Lack of Immediate Feedback

One of the perks of apps is instant feedback on progress. To replicate this manually, consider weekly reviews of your log to identify trends and adjust accordingly.

Overestimation of Caloric Needs

Many new trackers worry about underestimating their caloric intake. Focus on being consistent and improving your skills over time; it’s better to track inaccurately than not at all.

Social Situations

Eating out or attending social events can be daunting. Plan ahead by checking menus for calorie counts or searching for healthy alternatives, and don’t hesitate to enjoy the occasion — just keep your portion sizes in check.


Integration of Calorie Counting With Meal Prep

Integrating calorie counting with meal prep is a powerful strategy for maintaining consistency and ensuring you adhere to your calorie goals.

Planning and Portion Control

By preparing your meals in advance, you can accurately track calories for each meal before it is consumed. When you portion meals into containers, each meal can be weighed and logged ahead of time, enhancing your calorie awareness.

Efficiency in Tracking

Meal prepping decreases the likelihood of impulse eating, as you will have healthy options readily available, minimizing the temptation to stray from your calorie targets. Most meal prep containers can be labeled with calorie counts, simplifying the logging process.

Exploration of New Recipes

Trying new meal prep recipes can keep variety in your diet while allowing you to get better at estimating or determining calorie counts. This way, you avoid the monotony that can sometimes accompany calorie counting.


Different Tracking Methods: How to Count Calories Without an App

Counting calories without an app relies on various methods, each with its strengths. Here are the primary strategies:

  • Visual Estimates — Learn to recognize portion sizes using common objects for reference. A serving of chicken is about the size of a deck of cards; a cup of pasta is roughly the size of a tennis ball.

  • Hand Portions — Use your hand as a measuring tool. A fist represents a cup, a thumb represents a tablespoon, and a palm represents a protein portion. This technique works well when measuring tools are not available.

  • Photo Logging — Take photos of meals before eating to help with accurate logging later. This is especially useful at restaurants or social events.

These methods make calorie counting without an app more intuitive and manageable.


Tips for Social Situations While Calorie Counting

Social events are where most manual trackers lose control. Research shows that people consume 30–50% more calories in social settings than when eating alone. Here is how to stay on track:

Before the Event

  1. Plan ahead — Ask about the menu in advance so you can estimate calorie content based on typical ingredients.
  2. Eat a high-protein snack beforehand — Greek yogurt or a handful of almonds (150–200 kcal) reduces arrival hunger and makes it easier to choose wisely.

At the Event

  1. Choose wisely — Opt for dishes that align with your calorie goals. Focus on protein and vegetables; avoid heavy sauces and fried items.
  2. Use portion control — Apply visual estimates or hand portions to assess servings. When in doubt, take smaller portions.
  3. Watch beverages — Cocktails and sugary drinks add hidden calories. One cocktail can contain 200–400 kcal. Opt for water, sparkling water, or spirits with zero-calorie mixers.

After the Event

  1. Log immediately — Jot down the meal details right away or snap a photo for later reference.
  2. Do not compensatory fast — Skipping meals the next day leads to binge cycles. Return to your normal tracking routine the next morning.

Step 1: Calculate Your Daily Calorie Needs

Before tracking intake, determine how many calories your body burns each day.

The Harris-Benedict Formula

For Men: BMR = 88.362 + (13.397 × weight in kg) + (4.799 × height in cm) − (5.677 × age in years)

For Women: BMR = 447.593 + (9.247 × weight in kg) + (3.098 × height in cm) − (4.330 × age in years)

Apply Your Activity Multiplier

Activity LevelMultiplier
Sedentary (little exercise)BMR × 1.2
Lightly active (1–3 days/week)BMR × 1.375
Moderately active (3–5 days/week)BMR × 1.55
Very active (6–7 days/week)BMR × 1.725
Extra active (physical job + training)BMR × 1.9

Example: A 35-year-old woman, 65 kg, 165 cm, lightly active:

  • BMR = 447.593 + (9.247 × 65) + (3.098 × 165) − (4.330 × 35) = 1,373 kcal
  • TDEE = 1,373 × 1.375 = 1,888 kcal/day

For weight loss, subtract 300–500 kcal from your TDEE for a sustainable rate of 0.5–1 lb per week, per guidance from the American Journal of Clinical Nutrition.

Use the free calorie estimator and meal planner to calculate your personalized target in under a minute.

⏱️ Time: ~10 minutes


Step 2: Set Up Your Food Diary

Choose a tracking medium and create a structured log.

Choose Your Tracking Method

Option A — Notebook

  • Portable, works without internet
  • Requires manual addition every day

Option B — Spreadsheet (Google Sheets, Excel)

  • Automatic totals with formulas
  • Easy to duplicate recurring meals
DateMealFoodPortionCaloriesProteinRunning Total
4/5BreakfastOatmeal1 cup3006 g300
4/5LunchGrilled chicken salad2 cups45035 g750

Add a “Notes” column for hunger, mood, or energy to spot patterns over time.

⏱️ Time: ~10 minutes setup


Step 3: Find Calorie Information

Accurate data is the backbone of manual tracking.

Three Reliable Sources

  1. Nutrition labels — Check serving size and calories per serving on every package.
  2. USDA FoodData Central (fdc.nal.usda.gov) — Free database with 8,000+ verified foods.
  3. Restaurant nutrition guides — Most chains publish calorie counts online.

Calculate Calories for Your Portions

  • Label shows: 1 serving = 1 cup (200 kcal)
  • You ate: 1.5 cups
  • Your calories: 200 × 1.5 = 300 kcal

Common Mistakes That Inflate Error

  • Assuming “1 package” equals “1 serving” (often 2–3 servings)
  • Forgetting cooking oils (1 tbsp olive oil = 119 kcal)
  • Skipping beverages (one latte = 150–300 kcal)
  • Ignoring condiments (2 tbsp ranch = 145 kcal)

Research in the International Journal of Obesity shows untrained estimators undercount by 20–30%.

⏱️ Time: ~15 minutes to learn, then 2–3 minutes per food item


Step 4: Measure Portion Sizes Accurately

Portion measurement is where most manual trackers lose accuracy. Studies show people underestimate by 25–50% when eyeballing portions.

Essential Tools

ToolCostUse For
Digital kitchen scale$15–30All solid foods
Dry measuring cups$5–10Grains, nuts, flour
Liquid measuring cups$5–10Milk, oils, water
Measuring spoons$5Oils, nut butters, condiments

Measurement Best Practices

  • Weigh foods in edible form (usually cooked).
  • Use liquid cups for liquids, dry cups for dry goods.
  • For mixed dishes, weigh the total batch and divide by servings.
  • Zero your scale with the container before adding food.

Quick Visual Reference

FoodVisual GuideApproximate Calories
1 cup cooked riceTennis ball200
3 oz meatDeck of cards200–250
1 tbsp oilPoker chip120
1 oz cheesePair of dice110

Note: Weighing is always more accurate than visual estimates.

⏱️ Time: ~10 minutes daily


Step 5: Track Consistently

Consistency, not perfection, drives results.

Daily Tracking Routine

  1. Log immediately after eating — Memory fades within hours.
  2. Include everything — Beverages, oils, condiments, tastes while cooking.
  3. Pre-calculate recurring meals — Build a personal reference sheet.
  4. Round reasonably — Nearest 5–10 calories is sufficient.

Weekly Review

Every week, calculate:

  • Average daily calories
  • Average daily protein
  • Weight change
  • Adjust portions or food choices based on results

Why consistency matters: Research shows people who track every day lose 2× more weight than sporadic trackers. Skipping days breaks the habit and leads to systematic underreporting.

⏱️ Time: 5–10 minutes per meal


Step 6: Build a Personal Food Database

After 2–3 weeks of manual tracking, you will have a short list of foods you eat regularly. Write them on a single reference card or spreadsheet tab with their calorie values per standard portion.

This cuts daily logging time roughly in half and reduces lookup errors.

⏱️ Time: ~20 minutes once, saves 5+ minutes per day afterward


Examples of Common Meals and Their Calories

Knowing the calorie content of typical meals speeds up manual tracking and helps you make informed choices before eating. Here are calorie estimates for common meals based on USDA FoodData Central data:

Breakfast Examples

MealApproximate Calories
Oatmeal (1 cup) with banana and honey350
2 eggs, 2 slices toast, 1 tsp butter400
Greek yogurt (1 cup) with blueberries200
Protein shake (1 scoop) with milk280

Lunch Examples

Spaghetti with marinara (1.5 cups)400
Stir-fry chicken with rice (1 cup)480
4 oz steak with baked potato500

These are estimates. Always weigh your actual portions and check labels for precision. Building a personal meal list like this is one of the highest-value habits for manual trackers.


Common Mistakes in Manual Calorie Counting

Overlooking Hidden Calories

Many people forget to account for cooking oils, sauces, and condiments, which can add significant calories to meals. For example, just one tablespoon of olive oil contains around 119 calories. A restaurant salad with dressing can jump from 200 to 500+ calories.

Eyeballing Portion Sizes

Visual estimation leads to underestimating intake by 25–50%. Use a food scale or measuring cups for accurate tracking, especially for calorie-dense foods like nuts, cheese, and oils. A food scale pays for itself in accuracy within the first week.

Failing to Log Everything

Many trackers neglect to log snacks, drinks, or “just a taste” while cooking. Including everything you consume — no matter how small — is crucial for an accurate calorie count. The “I will remember it later” approach fails because memory fades within hours.

Inconsistent Weekend Tracking

Weekend meals often go unlogged. A Friday-night pizza and Saturday brunch can erase an entire week of weekday deficit. Track weekends too, even if you use estimates rather than exact measurements.

Trusting Package Serving Sizes Blindly

Many packages contain 2–3 servings, not one. Always check the servings-per-container line. A “single-serve” bag of chips often lists nutrition for half the bag.


How to Maintain Motivation While Counting Calories

Staying motivated can often be the biggest challenge. Here are some practical tips:

Set Achievable Goals

Breaking your larger goal into smaller, manageable milestones can keep you motivated. Celebrate small victories, like consistently logging meals for a week or hitting a weekly calorie target.

Incorporate Variety

Boredom can kill motivation. Experiment with new recipes and foods to keep things interesting, and ensure meals are enjoyable to sustain your interest.

Track Non-Scale Victories

Motivation can come from sources beyond the scale. Pay attention to energy levels, how your clothes fit, or improvements in your exercise performance. These factors can validate your efforts even if the scale does not budge immediately.

Real-World Example

One member of the National Weight Control Registry lost 65 lbs over 14 months using nothing more than a pocket notebook and a kitchen scale. She logged every meal for the first eight months, built a personal food reference list, and eventually transitioned to a calorie app once she felt confident in her portion estimates. Her key insight: “The notebook taught me what a real portion looks like. No app could have given me that education.”


Common Myths About Calorie Tracking

Misinformation about calorie counting stops many people from starting. Here are the most widespread myths and the evidence behind them:

Myth 1: “Calorie counting causes eating disorders”

Reality: Research published in Obesity found that structured calorie tracking does not increase disordered eating in healthy adults. The key distinction is method — tracking to inform choices is healthy; tracking to punish yourself is not. If you feel obsessive or anxious, take a break and consult a professional.

Myth 2: “All calories are equal, so food quality does not matter”

Reality: A calorie is a unit of energy, but your body processes 200 calories of chicken breast very differently from 200 calories of candy. Protein has a higher thermic effect (20–30% of calories burned during digestion) compared to fat (0–3%) and carbs (5–10%). Food quality affects satiety, hormones, and long-term adherence.

Myth 3: “Manual tracking is too inaccurate to be useful”

Reality: Studies show manual tracking achieves 85–90% accuracy with practice. A 10% margin of error is sufficient for weight loss — you do not need lab precision to create a meaningful calorie deficit.

Myth 4: “You have to track forever”

Reality: Most successful weight maintainers track consistently for 6–12 months, then shift to periodic check-ins. The portion awareness and calorie-density knowledge you gain during that period becomes permanent.

Myth 5: “Apps are always more accurate than manual tracking”

Reality: A calorie app is only as accurate as the user inputs. Crowdsourced food databases in some apps contain errors. Manual tracking with verified sources like USDA FoodData Central can actually be more accurate for less common foods.

Verdict

App-based tracking wins on accuracy, convenience, and sustainability for most people. Manual tracking excels at building foundational nutrition awareness. The ideal path: start manual for 2–4 weeks to learn portion sizes and calorie density, then graduate to a calorie app for long-term consistency.


When to Switch From Manual to App Tracking

Consider transitioning to a calorie app when you notice any of these signs:

  • Manual logging takes more than 20 minutes per day.
  • You frequently forget to record meals.
  • You want automatic macro and micronutrient breakdowns.
  • Your weight loss has plateaued despite tracking.
  • You eat out often and need instant access to restaurant data.

A calorie app removes friction from the process. Research in Obesity Reviews found that digital self-monitoring doubled weight-loss success rates compared with paper-based tracking because lower friction leads to more days logged.


How a Calorie App Complements Manual Skills

The nutrition awareness you build through manual tracking is permanent. When you move to a calorie app, you bring that knowledge with you:

  • You already know what a 4 oz portion of chicken looks like.
  • You understand that cooking oils add significant calories.
  • You can spot calorie-dense foods at a glance.

The calorie app then handles the tedious parts — looking up values, calculating totals, and generating progress reports — so you spend less time on logistics and more time making good decisions.

Use the free calorie estimator and meal planner to map out your first week of meals in under five minutes once you make the switch.


Frequently Asked Questions

What is the best way to count calories without an app?

The best way to count calories without an app is to use a kitchen scale for portion measurement, USDA FoodData Central for calorie lookups, and a notebook or spreadsheet for daily logging. Calculate your TDEE first, then weigh and log every meal immediately after eating. This combination gives you 85–90% accuracy with practice, which is sufficient for effective weight management. Most manual trackers spend 15–30 minutes per day on the process.

Can counting calories help with weight management?

Yes. Counting calories is one of the most evidence-supported strategies for both weight loss and weight maintenance. Research in Obesity Reviews found that self-monitoring of food intake doubled weight-loss success rates. The National Weight Control Registry reports that 74% of long-term weight maintainers used some form of food tracking. Counting calories creates the awareness needed to sustain a calorie deficit or maintain your current weight, whether you use an app or track manually.

Is manual calorie counting accurate?

Yes, when done with measuring tools and reliable food databases. Studies show manual tracking achieves 85–90% accuracy with practice, though beginners typically underestimate by 20–30% initially.

How long does it take to count calories manually?

Expect 15–30 minutes daily for measuring, looking up values, and logging. This drops to 10–15 minutes as you build a personal food database.

What can I use to track calories without an app?

You can use a notebook or a digital spreadsheet to manually track your meals, along with measuring tools like a kitchen scale and measuring cups.

Can I lose weight just by counting calories manually?

Yes. Research consistently shows that calorie tracking — manual or app-based — doubles weight loss compared to not tracking. The method matters less than consistency.

How do I count calories effectively without an app?

Effective calorie counting can be achieved through a structured approach: calculate your calorie needs, create a detailed food log, measure portion sizes accurately, and consistently track your intake.

What are the best methods for manual calorie tracking?

The best methods for manual tracking include using measuring tools (like scales and cups), visual portion estimates, and maintaining a food diary for organized record-keeping.

Why do people switch from manual to app tracking?

The top reasons are time savings (3–5× faster), instant food database access, automatic calculations, and better long-term adherence. Manual tracking works but demands more effort to sustain.

Do I need to track calories forever?

Most successful weight maintainers track for 6–12 months, then shift to periodic check-ins. The portion-awareness and calorie-density knowledge you gain stays with you permanently.

Which method is better for beginners?

App-based tracking is easier for beginners due to lower friction and built-in databases. However, starting with 2–4 weeks of manual tracking builds nutrition awareness that improves long-term success with any method.

What is the biggest mistake in manual tracking?

Underestimating cooking oils, condiments, and beverages. These “hidden” calories can add 300–500 kcal daily, completely erasing a moderate calorie deficit. Always measure and log them.

Is a calorie app safe to use every day?

Yes. Digital food diaries are classified as low-risk wellness tools. Reputable calorie app options store data securely and do not sell user information to third parties.

What are the benefits of counting calories manually?

Manual counting builds deep nutrition awareness, improves portion estimation skills, creates a stronger mindfulness effect than digital logging, and costs almost nothing. The psychological benefit of physically writing down each meal increases dietary self-awareness and accountability, according to research in Appetite. It also forces you to learn calorie values by heart, which makes future food decisions faster and more informed.

How long does it take to see results from calorie counting?

Most people see measurable weight-loss results within 2–4 weeks of consistent tracking, assuming a calorie deficit of 300–500 kcal per day. Initial weight changes may appear within the first week due to reduced water retention from lower carbohydrate and sodium intake. Visible body composition changes typically emerge after 4–8 weeks. Research in the New England Journal of Medicine found that consistent trackers lost an average of 1–2 lbs per week when maintaining a 500–1,000 kcal daily deficit. Tracking your food — whether manually or with a calorie app — is the single strongest predictor of weight-loss success.

How do I stay motivated while counting calories?

Focus on habit streaks rather than daily scale readings. Use the 80/20 rule (track precisely on weekdays, estimate weekends), set milestone rewards, share progress with an accountability partner, and switch to a calorie app if manual tracking becomes the reason you want to quit — consistency beats method perfection.

How many calories should I eat per day to lose weight?

Subtract 300–500 kcal from your TDEE for a moderate deficit (0.5–1 lb per week) or 500–1,000 kcal for a more aggressive deficit (1–2 lbs per week). The American College of Sports Medicine recommends that women eat no fewer than 1,200 kcal/day and men no fewer than 1,500 kcal/day without medical supervision.

How do you start counting calories?

Start by calculating your TDEE using the Harris-Benedict formula or a free online calculator. Then grab a notebook, weigh your next meal with a kitchen scale, look up the calorie value on the nutrition label or USDA FoodData Central, and write it down. Repeat for every meal. The first day is the hardest — by day three, the process starts to feel routine.

What are the best foods for calorie counting?

The best foods for calorie counting are those with clear nutrition labels and consistent portion sizes: packaged goods, dairy, eggs, raw meats, and frozen vegetables. Whole foods like rice, oats, and pasta are easy to weigh and have reliable USDA entries. Restaurant meals and mixed dishes are harder to track — when in doubt, overestimate by 10–20%.
