Why an AI calorie counter in Telegram actually works
Calorie counting fails for one reason — friction. Leam removes it.
Most diet apps die on day five. The reason is boring and consistent: calorie counting is a 40-second workflow in the best apps, and after a few days that workflow feels like a part-time job. Photo recognition and a chat interface change the math.
Calorie counting without the database hunt
Leam is an AI calorie counter built as a Telegram bot. You send a photo of your meal, the AI identifies the food and portion, and you get calories plus a full macro breakdown — protein, fats, carbs — in about three seconds. No food database to search. No serving-size confirmation modal. No ritual of opening an app before every meal. The friction that makes traditional calorie counters an exhausting daily chore is simply gone.
Science-backed, not vibes-backed
Under the hood, Leam uses GPT-4 Vision for food recognition and backs its calorie math with real nutrition science. Your daily target is computed from Mifflin-St Jeor BMR and a TDEE activity multiplier, then adjusted weekly against your actual weight trend — we don't pretend a fixed calorie number works forever. Read the full methodology in our guide to BMR, TDEE, and calorie deficits: see the blog posts linked below for details on the formulas and the research they rest on.
Designed for your life, not the gym
Telegram is where you already are. That means Leam works on iPhone, Android, Mac, Windows, the web — anywhere Telegram runs. Zero install. Zero signup. Russian and English are native, with voice input (Whisper) and photo as first-class ways to log. Retroactive entries handle natural phrasing like "yesterday I had pasta" so you're never locked into real-time tracking. The whole product is designed around one assumption: you'll only log meals consistently if logging is faster than thinking about logging.

What alcohol actually does to fat loss (it's not what you think)
A glass of wine isn't the end of the world. But it does something specific to your metabolism — and the knock-on effects matter more than the calories themselves.
