The jello is limited to 75-100 calories per day.
2 cups of low fat milk products per day, including yogurt.
4.5 cups of veggies per day - most usually include about 2 cups at lunch and dinner. Romaine lettuce counts....but also try for more nutrient rich veggies (spinach, peppers, tomatoes, etc.)
Rotisserie chickens are fine - no skin or dark meat though.
