Built by one engineer, his own data, and an AI cofounder.
Plait turns the recovery, sleep and strain your wearable already measures into what to eat today. 6,800+ athletes have connected a WHOOP, Garmin or Apple Watch beta so far.

The team
Plait is a team of one, plus the AI he builds with. Adam sets the product direction and reviews releases; automated checks validate the nutrition arithmetic in generated plans.
Adam founded Plait after years of having rich WHOOP data and no clear answer to the only question that mattered each morning: what should I do differently today? He has built AI automation and data systems across satellite communications, logistics and crypto, and brings that engineering discipline to fitness data.
AI & automation: machine learning, analytics pipelines, business intelligence systems
Engineering: software, signal processing, predictive modeling
Fitness data: WHOOP, Garmin and Apple Health metrics, recovery and nutrition timing
"I obsess over details in both fitness and technology. I built Plait so other data-driven athletes get the insights they deserve. Your wearable captures incredible data. Plait helps you actually use it to get better."
Adam builds and maintains Plait. AI proposes meals from a defined food catalog; the server calculates nutrition from the weighed ingredients and checks the daily totals. Personal plans are generated automatically and are not individually reviewed by a person.
Data analysis: recovery, sleep and strain patterns across the user base, statistical modeling, trend detection
Personalization: daily calorie and macro targets that adapt to each morning's recovery
Research: literature review with PubMed and NCBI citations in every article
Content: first drafts of guides and posts, fact-checked and edited by Adam
"With AI as a cofounder I can analyze like a team of statisticians and write like a team of researchers, while keeping the personal judgment only a human founder can bring."
The origin story
The photo that started it
"Approaching 40, I saw a photo of myself and had a moment of truth: fix it or forget it. Plait didn't exist yet, but the same data-driven approach I used to change my own body is what it now does for thousands of others."
Adam Eisenman
Before · age 39
The family photo. Out of shape, low energy, tired of generic advice.
18 months of tracking everything
After
Age 41
Lean and strong after 18 months of tracking everything.
Age 42 · gym
Still training on data. Every session, every meal.

The result of eating for recovery, not for a plan.
The turning point
At 39 Adam saw a family photo and barely recognized himself. Trainers, diet programs and fitness apps had all failed for the same reason: none of them were built around his actual data.
So he started tracking everything by hand: sleep, HRV, recovery, nutrition timing, workout performance. Spreadsheets became correlations, and the correlations turned up patterns no generic program had ever addressed.
The transformation took 18 months. The real breakthrough was the method: everyone deserves guidance based on their own data, not averages. That method became Plait.
How the human and the AI work together
A clear division of work: product judgment, generated meal ideas, and independently calculated nutrition.
01 · Human
Direction and review
Adam sets product direction and reviews changes. Content drafts go through a separate editorial review before publication.
02 · AI
Analysis at scale
AI proposes a weekly menu based on your calorie target and dietary preferences. Daily guidance uses your available sleep and recovery signals; missing data is clearly identified.
03 · Data
Evidence, not vibes
Ingredient nutrition comes from a curated USDA food catalog. Calories are calculated from protein, carbohydrate and fat, then checked against your daily target. Wearable calorie estimates and nutrition calculations remain approximations.
