Low FODMAP and calorie planning tools for practical meal decisions.
Each tool runs fully in your browser with static data and transparent assumptions. Use them for quick food checks, label review, calorie and protein estimates, and meal-planning context.
Choose a tool
Start with the meal question in front of you.
Labels, individual foods, swaps, full meals, and calorie targets need different checks. Pick the closest situation first, then move to another tool if the result needs more context.
Checking a packaged food label?
Use the full label checker when you have the complete ingredient list and want grouped risk notes.
Looking for hidden FODMAP concerns?
Use the hidden ingredients checker for quick scans of garlic, onion, inulin, polyols, lactose, and aliases.
Replacing a high-FODMAP ingredient?
Use the substitution finder when you need practical lower-risk swaps for cooking or shopping.
Planning calories around meals?
Use the calorie calculators for maintenance estimates, deficit targets, burn-time context, and cautious meal planning.
Planning protein around meals?
Use the protein calculator for daily targets, per-meal structure, diet adjustments, and cautious meal-planning context.
Checking one food or a whole meal?
Use the food checker for one ingredient, or the stacking calculator when several foods may add up.

Important note
This tool provides general FODMAP risk guidance only. It is not medical advice. Serving size and personal tolerance matter. Work with a doctor or dietitian if you have IBS, SIBO, or ongoing symptoms.
How they work
Quick guidance with clear limits.
These tools are meant to make Low FODMAP checks and calorie estimates easier without overstating certainty. They work best when you use the result together with portion awareness, symptom history, and professional guidance when needed.
01
Transparent estimates
Food tools use static ingredient data and calorie tools show their BMR, TDEE, and deficit assumptions, so results stay explainable.
02
Serving size still matters
A food can change risk depending on portion, preparation, and what else is in the meal. Treat each result as guidance, not a final verdict.
03
Not medical advice
These browser tools are built for quick food and calorie planning context. Work with a clinician or dietitian for IBS, SIBO, weight change, or ongoing symptoms.
