Appetite drops fast on a GLP-1. So does the body's interest in protein. Across the registration trials of semaglutide and tirzepatide, roughly 30 to 40 percent of the weight lost was lean mass, not fat. Steady is built to make that number smaller.
Protein is the first metric on the home screen. The daily target is set from your goal weight and your activity level, following the clinical literature on lean-mass preservation in caloric deficit, typically 1.2 to 1.6 grams per kilogram of goal body weight, which for most women lands near 120 grams.
Logging takes seconds. A food search powered by USDA and Open Food Facts. A barcode scanner for the items you eat most. Saved meals so the second time you log Greek yoghurt with berries, it is one tap. The weekly scorecard shows protein next to water, fibre, and dose adherence, the four lines that protect muscle on a GLP-1.
