First i had to give up having a large coffee and 2 doughnuts for breakfast!
I used to do cream cheese on bagel but cream cheese packet was only 2 grams of protein.
Look at number of grams protein compared to number of grams sugar in foods.
Max ratio of 1.5 sugar to 1 g protein for me. Exception is apples, thick rolled oats, they seem to stabilize my blood sugar.
Cottage cheese and pineapple a good breakfast. Trader Joes has frozen pineapple and other fruits without added sugar.
LOve bread and all other carbs including an occasional drink so have to severely limit myself or i don't feel good.
REad "Protein Power" or "The Zone" for information on which foods are protein rich. Protein power is low carb. Zone is balancing carb,protein and fat at each meal. A zone bar for an on the go breakfast keeps me going for 3-4 hours. Also like Kashi Go Lean, a protein fortified breakfast cereal.
