Gust calculates your daily protein target from your body stats, activity level, and a "protein aggressiveness" setting. You can adjust any of these.
How the math works
We use a Mifflin-St Jeor energy expenditure calculation, then layer on a protein-per-kilogram multiplier based on your goals. The result is your daily protein target (in grams).
Inputs:
Age, sex, height, weight.
Activity level.
Workout days per week.
Protein aggressiveness (how high you want to push protein vs. total calories).
Update your body stats
Tap the Profile tab.
Tap Edit Body Stats.
Update height, weight, age, sex, or activity.
Tap Save.
Your daily macros recompute immediately.
Adjust the protein aggressiveness dial
Higher aggressiveness = more grams of protein per kilogram of body weight. Useful if you're cutting, lean-bulking, or training hard.
Profile → Edit Diet (or Macros).
Move the protein aggressiveness slider.
Tap Save.
Update your workout days
Workout intensity changes your protein needs.
Profile → Edit Workout Days.
Pick the days you train.
Tap Save.
If you set a workout day, that day will get a slightly higher protein target on workout days (protein cycling).
I think the target is too low or too high
The default settings are based on sports nutrition research, but every body is different. Talk to a doctor or registered dietitian if you want personalized medical advice — Gust isn't a substitute for one.
