When manual targets make sense
- You are following a target from a coach, dietitian, or clinician.
- You already know your preferred calorie target from past tracking.
- You want a specific protein, carb, or fat split for training or food preference reasons.
- You are experimenting carefully and want to compare a few weeks of trend data.
Do not over-adjust too often
Manual control is useful, but changing targets every day makes trends harder to read. Pick a sensible target, log consistently for a couple of weeks, then adjust based on weight trend, adherence, hunger, training, and energy.
