How to track calories without it taking over your day
Tracking calories is two habits: writing down what you eat, and getting the portion roughly right. Most people give up on the first one because logging takes too long.
Here you'll find faster ways to log, when a food scale is worth the bother, and what to do after a week off (short version: just start again). Calsa was built around that first habit. Take a photo, scan a barcode or say what you ate, check the portions, done.
