It should be OK on Phase I - the light cream cheese, no pudding mix until Phase II.
HOWEVER, low fat cream cheese has 554cals, 42 grams of fat, 17 grams of carbs and 25 grams of protein. Ricotta (part skim milk) is 340/19/13/28 so it is by far the better choice - lower cals, lower fat, lower carbs and more protein. This is based on nutritional analysis of a cup of each in

Try the recipe with ricotta next time.
