You're not on a GLP-1 (or you're long past titration and eating consistently across the week), you want the most sophisticated adaptive macro algorithm on the market, and daily targets work fine for your pattern.
You need macro tracking that treats your week as a week. MacroFactor's weekly recalibration is smart but still hands you a daily number — a number that will be wrong for you three days out of seven on a GLP-1. Protokol Lab's rolling budget solves this explicitly.
If you're on a GLP-1, probably yes — at least for the tracking side. MacroFactor's adaptive algorithm is excellent but was designed for users with consistent day-to-day appetite. On a weekly injection cycle, the assumption breaks. Protokol Lab's weekly rolling budget is built around that pattern.
Some users do, but it's friction. Logging every meal in two apps gets old fast. If your priority is GLP-1 integration, consolidate on Protokol Lab.
Partial. Protokol Lab computes BMR and adjusts weekly targets based on trend weight, but MacroFactor is more sophisticated on pure expenditure math. Most GLP-1 users find the simpler approach is enough because medication, not exercise, is the dominant variable.
