When I first started the program I found it easier to count calories by using foods that are pre-portioned. Like applesauce in the cups, brown rice in the cups, lean cuisine panini as a treat for lunch and to keep peace with my husband I eat low calorie foods he prepares, but in a salad plate.
Also, I track what I eat daily and usually plan my meals and snacks for the day. I always include a salad and fresh fruit each day as snacks. I am not one to cook much and like things that are easy to fix like eggbeaters on a toasted whole grain english muffin.
