The slow rise (fat-protein units)

1 tbsp of mayonnaise (15 g) carries 12 g of fat and 0.1 g of protein, which is 1.1 fat-protein units. That is enough for a slow rise of about 3 hours after the carbohydrate’s own peak. Counted the way the app counts it, at 10 g of carbohydrate per unit, the whole glucose load of the portion is about 11 g.
