Is protein more important than calories on GLP-1?

On a GLP-1, hitting your daily protein target matters more than tracking every calorie. The medication suppresses appetite enough that most users land in a calorie deficit naturally, often a steeper one than is ideal. The risk is not that you eat too much, it is that you lose lean mass alongside fat. Adequate protein, around 0.8 to 1.0 grams per pound of body weight, is the single biggest lever you control to keep that lean mass while the deficit does its work. If you only track one number on a busy day, track protein. Calories tend to come out where they need to be when protein is at target and the medication is doing its job.
