I'm on a low carb diet and my usual breakfasts are as follows:
Fat free plain Greek yogurt (low in carbs) with Fifty 50 brand low carb jam or liquid Splenda and berries/Tropicana "Light" fruit punch or berry blend (low carb)/coffee with Calorie Countdown milk (low carb)
Puffed Kamut with Calorie Countdown milk (puffed kamut is like puffed wheat but has more fiber making its net carbs low (under 10 carbs per cup))
Yum! Fat free cottage cheese pancakes (find it on the net). It does contain about 1 Tbsp white flour per serving, but that's not much. There is a little fat, but one pancake is very satisfying with sugar free syrup or Fifty 50 jam. [I find Fifty 50 jam in the health/diet section of my store. Not sure if it would be amongst the other jams.]
Low carb flax seed muffins (find it on the net). Flax seed has so much fiber that the net carbs are zero. Other ingredients add only a couple of net carbs.
