It is easy to overeat while dining out. To control your portions, split dishes with other guests at your party.
For example, order an appetizer or dinner salad and one entree for two people. Often, one entree portion at restaurants are actually at least two portions. If dining alone, ask to have half your meal packed to go and given to you after you settle your bill. By dining this way, you will save yourself anywhere between 300 to 1000+ calories.
