I've weighed 260 lbs, and I've weighed 180 lbs. Most of my life I've been somewhere in between, gaining and losing the same ground since I was sixteen. What finally stuck was not more discipline. It was endurance sport, and numbers I could trust.

I'm an amateur triathlete in Portland, Oregon, and a data scientist by day. After two Ironman finishes, seven 70.3s, and a 3:29 marathon, I decided to build the tool I needed for my own problem: losing body fat without compromising the training, twelve-plus hours a week of it, as I chase the pointy end of my age group on the way to Kona in 2028.

Fed State exists because my nutrition app did not know what my training app knew. It handed me the same calorie target on a five-hour ride day as on a rest day. It was on me to do the math, and when you're fatigued under high training load grabbing take-out is much easier. So I built the system I needed: targets that scale with the training, a protein floor that does not move, and a deficit that comes out of the easy days instead of the sessions.

The rule behind all of it is simple: fuel, not starvation. Underfueling is the mistake endurance athletes make quietly, and it costs health and speed at the same time. I know this from experience. Fed State is an educational tool built on published evidence. It is not medical advice, and it will never tell you to starve your training to chase a number.

I run the system on myself, in public. Every Monday I post the week's training, fuel, and trend weight, good weeks and bad, at @zackryangodwin on Instagram. The app gets built only as fast as the proof earns it.
