Approximate · estimate label always visibleThe target shows its work.
Coach uses the relationship between logged intake and weight trend. When the record supports a change, the old target stays visible beside the new one.
Consistent inputsUseful corrections need regular food logs and weigh-ins. Thin data does not earn a confident update.
Visible reasoningThe screen shows the intake average, weight trend and maintenance estimate behind the change.

Logging dinner
Search an entry, then translate your plate into its serving size.
Say “2 rotis, katori rajma,” review the grams, then add it.
Indian food numbers
Coverage, source quality and portion definitions vary by entry.
IFCT 2017 and INDB appear first when they cover the food.
Where a number comes from

Every food carries a source tier you can inspect.

“Every app before this made me weigh dal in cups. I just tell Mentzer what I ate at home and it gets it right. For the first time, tracking felt like something I could keep doing, not another thing I'd quit in three weeks.”

“The protein ring is honest. When it said my maintenance was 200 kcal higher than the formula, my lifts finally started moving again. Turns out I wasn't lazy. I was underfed.”

What people ask before they trust a tracker.
Is there a free plan?
Yes. Logger stays free and needs no card. It includes chat, search and barcode logging, source labels, and daily calorie and macro totals. Coach adds target updates, plateau explanations and nudges.
Does it cover regional food beyond roti and dal?
The record includes foods from across India and prioritizes IFCT 2017 and INDB when they cover the item. Other records carry their own source label. Foods that need an estimate are marked est.
What happens when Mentzer cannot find an exact match?
You can review the suggested foods and grams before adding them, edit the portion, or create a custom food or recipe. An estimated entry stays visibly marked instead of being presented as measured data.
Do I have to weigh every meal?
No. Plain-language logging gives you a practical starting estimate, and you can edit the grams when you know them. Weighing improves precision when the exact number matters to you.
How long does Coach need before it adjusts my target?
Coach needs enough consistent food logs and weigh-ins to compare intake with weight trend. Sparse records delay a useful correction. The app keeps the starting target until the data supports a change.
What's the difference between Logger and Coach?
Logger records meals, sources and daily macro totals. Coach uses those records with your weight trend to estimate maintenance, suggest target changes and explain plateaus. Logger stays free if you do not add Coach.
Is my food and weight data private?
Mentzer does not sell your data or serve ads. You can export what you have logged at any time.
