Directive — Precision Body Composition Engine
2026 Charter intake

Most diets don't fail on willpower. They fail on bad math.

Three measurement errors can quietly undo months of good work. Directive separates water weight from your real trend, counts only the calories a workout burns beyond your resting metabolic rate, and lets you log a meal in seconds.

Illustration with sample data.

Three measurement errors. Every one of them fixable.

None of these are willpower failures. They're bad inputs, and they compound.

Your watch can overestimate your burn

An example: a watch logs a 60-minute medium lift as 420 kcal. About 80 kcal of that you would have burned at rest anyway, and the watch also counts the rest between sets as hard work, so the workout itself burned about 205 kcal beyond your resting metabolic rate. Eat back the full 420 and your deficit shrinks.

That overnight spike isn't fat

Salt, heavy training, or hormonal shifts can move the scale by several pounds overnight, and it is hard to distinguish water weight from fat by eye. Directive's trend filter separates likely water swings from your underlying trend, so you can see a spike for what it is before you cut calories to fix it.

Weighing almonds is not a plan

Measuring 14 grams at a time works for a few weeks, then the cognitive drag sets in and people quit. Precision doesn't require being locked in a digital prison. Log a meal by hand: a palm of protein, a fist of carbohydrate, a thumb of fat, in seconds. Flag a restaurant meal with one switch.

Or try Precision tracking: save a meal you eat often and add it with one tap. Take a snapshot of a recipe, tweak it if you like, and Directive works out the macros for a serving, so you can eat it all week without complicated logging. Or just say what you ate.

Built around how bodies actually behave

Not a calorie ledger. A dynamic model of your body under training, stress, and restriction.

The Event Allowance

Real life happens. Instead of blowing your diet on a Saturday night and staring at a red failure notice, schedule an Event Allowance. Directive takes a small amount off the days before and adds it to your event day, so the week still adds up. Your calorie floors always come first.

The Rebound Shield

Hitting your goal weight is only half the flight. Landing without bouncing is the hard part. When you reach your target, Directive walks your calories back up over six weeks to find your maintenance level, a transition designed to help you avoid the rapid regain that follows most strict diets.

Protein comes first

In a deep deficit, or while using a GLP-1 medication, holding on to muscle gets harder. Directive sets a protein floor for every day and raises it when you cut aggressively or use a GLP-1 medication. Protein and fat floors come first; carbohydrates fill what is left.

Built for adults, not for streaks

No guilt, no streaks, no mid-day nags asking if you drank water. Directive sends no reminders at all. Miss a day, or take a week off, and nothing scolds you. Log in again with your updated weight and it picks up from where you left off.

Bring your numbers to your appointment

Instead of a 40-page diary, Directive puts your weight trend, estimated body composition, resting heart rate, sleep and energy intake into a clean PDF for your doctor. A trainer's version covers training volume and steps, and a nutritionist's covers intake, macros and your protein floor. Each is a summary of what you logged, not a medical record.

The Afterburner Protocol

For deadline-driven targets, like a wedding, a beach vacation or another immovable date, when you need to be more aggressive to hit that target. A temporary, aggressive deficit for a short push, capped at 14 days. Directive tells you what you are trading for the speed, then leaves the decision to you.

The three Shields

Each one covers a stretch where the scale is at its least trustworthy.

THE FIRST 10 DAYS AFTER TOUCHDOWN

Scale Shield

The first 10 days after touchdown, when you have reached your goal weight and water-weight swings are expected. The app reminds you to trust the trend line.

FOR WOMEN: THE WEEK BEFORE YOUR PERIOD

Fluid Shield

For women who track their menstrual cycle. In the week before your period is due, the app expects water retention and treats those weigh-ins as less reliable.

THE SIX WEEKS AFTER TOUCHDOWN

Rebound Shield

Engineered post-diet transitions that step your calories back up strategically, designed to help protect your hard-earned muscle and prevent the classic post-cut weight rebound.

Five instruments. One coherent trajectory.

Everything Directive tracks routes through a dedicated instrument panel.

Fuel

Agnostic energy balancing. Hit your calorie target, hold your protein and fat floors, and plan an Event Allowance for the nights that matter. Log a meal in seconds by portion, pick a food, meal or recipe you've saved, or type in the numbers when you have them.

Velocity, Touchdown and Beyond

Velocity is the rate of weight loss you choose for yourself. Touchdown is the day you reach your goal weight. Rebound, regaining weight after a diet, is what every dieter wants to avoid, so after touchdown Directive runs a six-week reverse diet that steps your calories back up, designed to help limit it. For the longer term, Cruise Control holds your calories at maintenance to help you keep the weight you have reached.

INTENSITY

Weekly Directive

Every Sunday, an audit reviews your week, updates your maintenance estimate and tells you plainly whether or not your calories need to change. When they do, you choose how to make the change: eat a little less, walk a little more, or a mix that you determine.

WEEKLY BRIEFING

You logged 6 of 7 days, ate 3,150 kcal less than your estimated burn, and your trend weight dropped 0.9 lb. Your deficit streak continues.

Your calories come down this week by 150 calories per day.
