A web app designed to be accessed using mobiles for tracking weight and calorie consumption. Based on the Hacker Diet methodology.

Hack Weight uses a SQLite3 database, that can be created with the following SQL:

PRAGMA foreign_keys=OFF;
BEGIN TRANSACTION;
CREATE TABLE users ( username string primary key, password string not null );
CREATE TABLE settings ( id integer primary key, username string not null, setting_key string not null, setting_value string not null );
CREATE TABLE weight_entry ( id integer primary key, username string not null, date string not null, weight real not null );
CREATE TABLE calorie_entry ( id integer primary key, username string not null, date string not null, amount integer not null, category string not null );
COMMIT;

I've always struggled with weight, largely because I love good food and good beer, and especially pubs that provide both. I also love pizza, which no doubt doesn't help, and the city I live in literally runs a gourmet burger month every year where the challenge is to try as many different, large and rich burgers as you can. Oh, and they also run a pretty good craft beer festival. Add to that my penchant for spending 95% of my waking hours in a chair in front of a screen and...you get an average BMI of 'Obese'.

Around 10 years prior to creating this, I found the Hacker Diet (discovered while browsing Deus Ex text transcriptions from nuwen.net, the personal blog site of Stephan T. Lavavej). Giving it a go, I dropped from 105kg down to 82kg, a weight I managed to keep for five years or so until I met my Wife. She shared my preference for good food, beer and company (though she wasn't much of a beer person prior) and we both ballooned. Especially when our dog and then our daughter came alone. Stress relief through technical alcoholism is a thing people.

So I'm doing the diet again, and I thought this time I would knock together an app to support it, in my new favourite language Go. Any excuse, right?
