Founding membership · first 50 only

You don't have a willpower problem.You have a damaged metabolism.

Every diet you white-knuckled taught your metabolism to burn slower and hold on tighter. That is your biology protecting you from starvation, doing exactly what it evolved to do. The way back runs opposite to everything you were sold, and it starts the day you stop eating less and start eating more.

Diet culture lied to you

Eating less is what slowed you down.

Nearly three in four American adults are overweight, and almost every one of them followed the same rules you did. The problem was never your discipline. It was the rulebook.

Eat less, move more

You were told
Cut your calories and grind it out.
The truth
Feed a healthy body around 1,570 calories a day and its metabolism falls by roughly 40%, then fights to hold every pound. Restriction is what taught your body to burn slow.
Minnesota Starvation Experiment, 1944-45

Calories in, calories out

You were told
It's simple math.
The truth
Your body is not a furnace you balance on a spreadsheet. Seed oils jam the part of your cells that burns fuel, so the same calories get stored instead of spent.
Seed oils block glucose oxidation

Carbs make you fat

You were told
Go keto. Cut the carbs.
The truth
Your thyroid runs your metabolism, and it needs carbohydrate to make its active hormone. Strip carbs for months and your thyroid output drops, your body cools, and your metabolism slows with it.
Thyroid and T3

Just train harder

You were told
Push through. Earn it in the gym.
The truth
Punishing workouts keep your stress hormones high and your fat loss stuck. A ten-minute walk after each meal does more for your metabolism than a session you need three days to recover from.
Cortisol and recovery
The number
74%

of American adults are overweight or obese. Every one of them was handed the same rulebook you were. The rulebook is the problem.

The way back

Feed the furnace and it climbs back.

Your metabolism works like a furnace. Starve it and it burns low and cold, and you feel it in every hour of your day. Feed it real, single-ingredient food and it recovers, and your energy returns with it. We build the exact plan for your body and walk you through it one day at a time.

Built for women, too

The research forgot half the population.

Only 6% of fitness studies are run on women, so the standard plan was built for someone else. For our female members, every protocol is shaped around the physiology the research skipped.

Muscle loss

You were told
Lift heavy and stay in a deficit.
The truth
Women lose around 3% of their lean muscle each decade after 30, unless protein stays near 1.6 g/kg with creatine on board. A deficit only speeds it up.
Smith-Ryan 2021

Iron and fatigue

You were told
You're just tired, push through it.
The truth
Women's iron needs run up to twice as high as men's, yet most multivitamins under-dose it. What gets written off as exhaustion is often low iron.
Sim 2019

Protein and satiety

You were told
Eat like a smaller man.
The truth
Generic plans leave women under-eating protein, which stalls the metabolism and costs lean mass. We set your target to your own body.
Phillips 2016
The piece every other plan misses

A woman's metabolism and energy rise and fall across the weeks of her cycle. Almost no diet or workout plan accounts for that. We do.

For most of the month a one-size plan is fighting her hormones instead of working with them. The same training that builds her up in one phase wears her down in another, and the macros that feel easy one week leave her starving and stalled the next. When the plan moves with her cycle instead of ignoring it, the cravings ease and the progress finally starts to hold.

Here is what working with your cycle looks like across a typical 28-day month, week to week.

Menstruation · days 1-5

You were told
Push through it and keep your normal training.
The truth
These are your rest-and-recover days. Hormones bottom out and your period drains iron, so ease off the hard training and lean on sleep and iron-rich food like red meat to help replace what you lose.
Iron loss during menstruation

Follicular · days 6-13

You were told
Stick to the same steady cardio all month.
The truth
As estrogen climbs, your energy and strength climb with it. This is the week to train hard and lift heavier, and your body handles carbs better now too.
Rising estrogen and strength

Ovulation · around day 14

You were told
Treat every session like an all-out, max-effort day.
The truth
Estrogen peaks and so does your strength, which makes it a strong day to push. Warm up thoroughly first, because that same estrogen loosens your joints and leaves you more prone to injury right now.
Estrogen and joint laxity

Luteal · days 15-28

You were told
Cut calories harder when the bloating and cravings hit.
The truth
Your metabolism actually burns more now, so slashing food is the worst move you can make. Feed the higher demand and pull your training back as your period nears, and the cravings usually quiet down once it starts.
