A useful record.
Even with gaps.
You do not have to fill in the past to start again. Record what you can today, then see what your records show over time.
Review the estimate.
Decide what to save.
Take a photo or describe what you ate. Review the ingredients and calorie estimate, adjust what needs changing, and save.
Already know the calories? Enter the total. Your supplied calories are kept.
Record a meal
A missed day does not mean starting over.
See the last seven dates, with recorded calories, weight and gaps. Open a day if you want to correct it, or continue with your next meal.
Earlier records still count. Filling every gap is optional.
Explore 7 Days
Look beyond a single weigh-in.
See how your recorded weight changes over time, with a seven-day average when enough measurements are available.
See what changed, with clear limits on what the records can explain. A trend alone does not tell you why.
View Progress
Keep your destination in view.
Your current weight and chosen target, together on a visual BMI reference. Set your goal and usual activity profile for an estimated daily calorie reference.
Your goal stays yours to change. Calorie and BMI references are not medical advice.
Review My Goal
A few things to know.
What if I miss a few days?
Start with your next meal. Your earlier records stay useful, and you do not have to fill every gap to continue. If you remember a past meal, open that day and record what you can; an approximate entry can still be useful.
How accurate are calorie estimates?
AI estimates are approximate. Review the whole-meal confidence and edit ingredients, portions or calories before saving. Calories you explicitly provide are kept rather than replaced with an estimate.
Can DeficitFlex explain why my weight changed?
It can show changes in your recorded weight and the evidence available. A weight trend alone cannot establish the cause, and a partial meal log is not your full intake. DeficitFlex does not promise weight loss or automatically tell you to eat less when progress is unclear.
Do I need an account?
Sign in with Google for AI estimates and record synchronization. You can record known calories without AI in your browser. Meal photos remain on that device and do not sync between devices; photos submitted for AI analysis are sent for processing.
