Why fat quality matters

Conventional calorie trackers treat fat as a single bucket. Feast splits fat into saturated and unsaturated components because this ratio is strongly linked to cardiovascular risk.

Feast emphasizes keeping saturated fat under 6% of total calories, with a warning band above 10%.

What Feast computes

For each day, Feast aggregates:

Saturated fat (SFA): grams from dietaryFatSaturated.
Unsaturated fat (UFA): grams from dietaryFatMonounsaturated and dietaryFatPolyunsaturated.
Total energy: daily calories from dietaryEnergyConsumed.

Feast converts grams to energy using 9 kcal per gram and calculates the percent of daily calories coming from saturated fat: sfaPctKcal = (sfaG * 9) / max(kcal, 1).

Chart behavior in the app

Time scales: weekly (7-day) and monthly (31-day) views.
Interactive details: tap a day to see total fat and SFA percent.
Targets: soft cap at 6% SFA calories, hard cap at 10%.
Goal-aware filtering: averages exclude low-log days below 800 kcal or below 60% of your energy goal.

The averages are calculated on qualifying days only, but the chart still displays every day so you can see when intake was sparse.

Why Feast is different

Most apps only show total fat grams. Feast shows how the balance between saturated and unsaturated fats shifts across the week and month, because that ratio is what matters for heart health.
