Quick Add

Quick Add is the feature that lets you log a calorie estimate — typically with optional macros — without tying it to a specific food entry. You type "450 calories, 30g protein" and tap save. It's a lifeline for situations where precise logging would either take too long or be impossible.

What it looks like in each app

• MyFitnessPal: "Quick Add" under each meal slot. You can add just calories, or calories + macros on paid plans.
• Cronometer: "Quick entry" with calories and customizable nutrient fields.
• MacroFactor: manual macro entry supports quick-add style logging.
• Lose It!: "Quick Add" with calorie + macro fields.
• Yazio: similar quick-add with calorie entry.

When it's the right tool

• Restaurant meals not in any database. Small local places.
• Friend's or family's cooking. You can guess total calories better than you can itemize every ingredient.
• Vacations. Trying to track abroad where databases and barcodes mostly don't apply.
• Buffet or multi-taste meals. Six different small plates where itemizing is more error than estimation.
• Emergency speed. You need to log and move on — log rough, adjust later if you want.

The accuracy cost

Quick Add is only as accurate as your estimate. Research on how well people guess restaurant meal calories (Block et al., JAMA Internal Medicine; Urban et al., JAMA) shows typical estimation errors of 20–50%, with a strong bias toward underestimating. If you Quick Add "600 calories" for a burrito, there's a solid chance the real number is 750 or 900.

How to be less wrong

• Anchor to known foods. "This looks like about 1.5 chicken burritos, so 900–1000 calories."
• Add a mental tax. Most people underestimate; mentally add 15–20% to your honest guess.
• Log macros when the app supports it. Protein is usually easier to estimate than calories; entering 30g protein roots the calorie estimate in something concrete.
• Prefer known menu items. If a chain version exists, use that database entry instead of Quick Add.

Adherence vs accuracy

The coaching frame: an imprecise log is infinitely better than no log. If the choice is Quick Add or skip the meal entirely, Quick Add wins every time. The gap between "no data" and "rough data" is huge; the gap between "rough data" and "precise data" is smaller. Don't let the perfect be the enemy of the tracked.

When it becomes a problem

Quick Add is a tool, not a strategy. If half your daily calories are Quick Add entries, your log is directionally useful but not precise enough to troubleshoot a stalled weight goal. When that happens, back off Quick Add for a week, log with real entries, and see what your real numbers are. Then return to mixed mode.
