Best thing I ever did was take 'the idea' to use measuring cups to control my portions. 1 Cup for protein 1 cup for starch/carbs and 2 cups for veg (Steamed, grilled, etc.) if it's a salad mixed - 2 cups (Then 1 cup after only if still hungry). This can be very easy and has helped me to curtail my portions down to a THIRD of what I USED to eat!
Pasta with sauce - 1 cup pasta 1/2 cup sauce (or if it's 'meaty' maybe reverse the measurements) Scrambled eggs for the family in a huge pan? 1 cup scrambled eggs! saute some spinach & Mushroom (dry fry) for the side!
