Nutrition and weight

Nutrition and weight are the other half of the picture: without them, the coach sees only training load and recovery, but not energy balance.

FatSecret nutrition diary

The service connects to FatSecret — a popular nutrition diary with a barcode scanner and a database of ready-made meals.

1. Create a FatSecret account if you don't have one yet — the app is free and available for iOS and Android.
2. In your 1trAIner dashboard, open the account menu → "Connections" and select the FatSecret tile.
3. Grant access on the FatSecret page. Your password stays with FatSecret: the service only gets access to your diary via OAuth.
4. Keep your diary as usual — the data will be pulled in automatically.

The coach receives your daily calories, protein, fat, and carbohydrates, as well as day-to-day trends — and compares them with energy expenditure from Garmin.

What this gives you

• a warning about underfueling before a high-volume day;
• an explanation for stalled recovery during a chronic deficit;
• an honest answer to "why isn't the weight coming off" — based on intake and expenditure, not guesswork.

You can ask right in the chat: "how's my nutrition this week?" or "will I have enough energy for tomorrow's long run?". The coach doesn't log nutrition from food photos — use FatSecret for tracking.

Where weight comes from automatically

• Garmin Connect — from Garmin Index scales or from weight entered in Garmin Connect. Updated roughly every 6 hours; on first connection, 5 years of weight history are pulled in.
• Polar — weight from your Polar Flow physical information.
• COROS — weight from your COROS profile.
• The 1trAIner iPhone app — weight and body fat percentage from Health, where many smart scales write them.
• Personal URL for your scales — for scales that write to Health via an automation: dashboard → "Connections" → "Smart scales". There you'll find the "Personal URL for your scales" field and the "Create link" or "Regenerate" and "Copy" buttons. The iPhone automation sends measurements to this URL.
• FatSecret — weight from the diary fills in only the days with no other measurement: scale data takes priority.

How to log weight manually

• In the chat: "my weight is 71.5" — the coach will log it and confirm.
• In the mini app: the "Weight" tab, the "Weight, kg" field, and the "Save" button. The same is available on the "Dashboard" in the weight block.
• With a photo: send a picture of your smart scale display to the chat — the coach will recognize weight, body fat percentage, muscle and bone mass, water, and visceral fat if they're on the screen, and reply "Body composition recorded". If the numbers can't be read, it will ask you to type your weight.

All measurements go into a single weight diary, wherever they come from.

Photos of lab results

Lab test forms aren't saved from photos: the coach will reply that there are no body composition metrics on it and ask you to send the results as text. The service doesn't draw medical conclusions — discuss them with your doctor.

How to disconnect FatSecret

In "Connections" in your dashboard, open the FatSecret tile and click "Disconnect": access to your diary is revoked and new data stops coming in. The nutrition history already imported stays in your account.

What you see in the dashboard

• a weight chart and body composition trends across all sources at once — chat, app, watch, scales;
• calories and macros (protein, fat, carbs) by day alongside your training load;
• an activity log where recognized photos keep a thumbnail of the original picture.

Consistency in measuring

Weigh yourself under the same conditions: in the morning, after using the bathroom and before breakfast. Fluctuations of 1–1.5 kg within a day are normal and reflect changes in water and gut contents, so focus on the trend over several weeks rather than a single reading.
