Ideal Weight Ideal weight is the weight at which a person is the healthiest. It is when a person eats when hungry and stops when full. Numbers to consider include height and weight charts, Body Mass Index (BMI), % body fat, cholesterol levels, blood pressure and fitness levels. The ultimate determination is the health of the body systems.
Hunger vs. Appetite Hunger- The physical need for food, felt in the stomach Appetite- The psychological desire to eat felt in the mouth, based on emotions such as stress, boredom and/or depression. The smell and taste of a food can cause a person to want to eat when they are not hungry. The need to be social can also be a factor in eating for appetite.
Nutrition Guidelines Balance calories with physical activity to manage weight Consume more of certain foods and nutrients such as fruits, vegetables, whole grains, fat-free and low-fat dairy products, and seafood Consume fewer foods with sodium (salt), saturated fats, trans fats, cholesterol, added sugars, and refined grains
