Why How You Log Matters
FuelForm estimates calories and macros from what you show or tell the app. The AI is strong — but it is not magic. A blurry photo of half a plate, or a voice note that says "I had pasta," forces the system to guess portion size. That guess might be off by hundreds of calories.
The good news: you do not need perfect logging. You need consistent, slightly better inputs. A few seconds of setup when you log — especially with a photo — usually beats fixing wrong numbers later.
This guide covers all three ways to log: photo, voice, and typed text.
Photo Logging — Your Best Tool for Portion Size
Photos are the fastest way to log a full meal. The camera gives the AI shape, color, and context — but portion size is the hardest part. Help the model by making size easy to see.
Shoot from above, in good light
Hold the phone directly above the plate (roughly 45–90° from the table). Side angles hide how deep a bowl is and make piles look smaller or larger than they are.
- Use daylight or a bright room when you can
- Avoid heavy shadows across half the plate
- Tap to focus on the food, not the table
Show the whole meal
Fit everything you ate in one frame when it is one meal. If you only photograph the salad and not the bread on the side, the log will miss calories you actually ate.
For mixed dishes (stir-fry, curry, pasta bowl), one clear photo is still fine — just do not crop out obvious add-ons (rice on the side, dressing cup, bread basket).
Put a size reference in the frame
This is the single biggest upgrade for photo accuracy.
Place a standard spoon, fork, or knife next to the plate — not hidden under the food. The AI uses familiar object sizes to judge how big the portion is.
What works well:
- Tablespoon or dessert spoon beside a bowl
- Fork or knife along the edge of the plate
- Your hand in frame (palm near the plate) if nothing else is available
What works less well:
- Tiny spoons far from the food
- Cutlery buried under the meal
- Decorative tiny forks that are not standard size
You do not need to mention the spoon in a caption — just having it visible in the photo is enough.
Separate items when it is easy
If your plate has clearly separate foods (chicken, rice, vegetables), spreading them slightly helps the AI count each part. A single messy pile is still loggable — just expect a review step more often.
Packaged foods — show the label
For bars, yogurt, frozen meals, or anything with a label, add a second photo of the nutrition label or the product name on the front. Branded products are matched more accurately when the name on the package is readable.
If you already know the weight (e.g. "150 g chicken breast"), say it in voice or text — that beats any photo guess.
What to avoid in photos
- Lids closed on containers (soup, meal prep) — open them or log by weight
- Extreme close-ups with no context for size
- Dark restaurants — one quick move to better light is worth it
- Screenshots of delivery apps instead of the real meal — log the meal you ate, not the menu thumbnail
Voice Logging — Be Specific Out Loud
Voice is fastest when your hands are full. Accuracy depends on how much detail you say.
Say quantities, not just food names
Weak: "Chicken and rice" Strong: "200 grams grilled chicken breast and one cup cooked white rice"
Weak: "A salad" Strong: "Large Caesar salad with chicken, no croutons"
Weak: "Some nuts" Strong: "About 30 grams almonds"
Counts help: "three eggs," "two slices whole wheat bread," "one medium banana."
Weights are best: grams or ounces for meat, rice, pasta, cheese, and snacks.
If you are unsure of weight, describe the container or serving: "half a standard restaurant plate of pasta," "one fist-sized portion of potatoes."
Name the brand when it matters
"Quest chocolate chip cookie dough bar" beats "protein bar." "Chobani plain Greek yogurt, 170 grams cup" beats "yogurt."
Speak in your app language
Set your app language in Profile if voice recognition struggles. Short, clear phrases work better than long stories.
Typed Text — Same Rules as Voice
Everything for voice applies to typing.
Strong log examples:
- "150 g salmon, 120 g roasted sweet potato, 1 tbsp olive oil"
- "McDonald's Big Mac, medium fries, diet Coke"
- "Homemade oatmeal: 50 g oats, 200 ml milk, 1 tbsp peanut butter, half banana"
Weak log examples:
- "Lunch"
- "Healthy bowl"
- "Cheating a bit today"
The more precise you are, the less you will need to edit calories afterward.
Confidence, Review, and Your Daily Total
After analysis, FuelForm may show confidence or ask you to review a meal.
- High confidence — The estimate is likely close; still skim macros if the meal matters to you.
- Review needed — The AI is unsure (often portion size or mixed dishes). Tap approve if it looks right, or edit amounts before approving.
Important: Meals waiting for review do not count toward your daily totals until you approve them. Check pending reviews so your day stays accurate.
When in doubt, add one detail (grams, pieces, or "tablespoon of oil") and log again — or edit the entry manually.
Quick checklist before you send
Photo
- Overhead or clear angle, good light
- Full meal in frame
- Spoon, fork, knife, or hand for scale
- Label visible for packaged foods
Voice or text
- Food names are specific (not "lunch")
- Quantities: grams, cups, pieces, or slices
- Cooking method or extras if they add calories (oil, sauce, cheese)
After logging
- Review any "needs review" meals before closing the app
The Bottom Line
You do not need laboratory precision. You need a repeatable habit:
- Photo: overhead shot + something for scale in the frame
- Voice or text: numbers beat adjectives
- Review: approve or fix uncertain meals so your day stays honest
Spend five extra seconds when you log — especially with a spoon or knife in the photo — and let the AI do the heavy math. That is how you get a diary you can actually trust.
