Weight-Watchers "Momentum" program; for-example U.S. patent 6,878,885:
Food "POINTS" formula-calculation is based on calories, grams fat, & grams fiber;
p = calories/(50, or 70) + (fat_grams/12) - min(fiber_grams,4)/5
Based on your weight-loss goals & progress, you have a daily or weekly "POINTS" budget.
You "earn" Activity-Points;
PA = activity_weighting( 0.05=low-intensity, 0.07=moderate-intensity; 0.18 to 0.20=high-intensity) x Kilograms_body_weight x activity_minutes / 100
