|Underweight||BMI less than 18.5.|
|Healthy Weight||BMI of 18.5 to 24.9. This BMI range also has the lowest risk of death. Remember, there is no ideal body weight for each person, but there are ranges for a healthy body weight.|
|Overweight||Body weight that exceeds the recommended guidelines for good health; A BMI of 25 to 29.9|

|Body Mass Index (BMI)||Measure of body weight in relation to height. It can be inaccurate for people with lots of muscle tissue.|
|Energy Balance||Relationship between caloric intake (in the form of food) and caloric output (in the form of metabolism and activity). If you take in more calories than you use through metabolism and movement (positive energy balance), you store these extra calories as body fat. If you take in fewer calories than you need (negative energy balance), you draw on body fat stores to provide energy.|
|Thermic Effect of Food||Estimate of the energy required to process the food you eat.|
|Basal Metabolic Rate (BMR)||Rate at which your body uses energy for basic life functions, such as breathing, circulation, and temperature regulation.|
|Healthy Body Weight Guidelines|| 1. Acceptable Body Mass Index (BMI)|
2. Fat distribution that is not a risk factor for illness.
3. Absence of any medical conditions that would suggest the need for weight loss.

Fat is very easy to process and has very little thermic effect, while protein is hard to process and has a much larger thermic effect.|
|Basal metabolic rate (BMR):||The rate at which the body uses energy to maintain basic life functions (very similar to the amount of calories burned at rest). About 60-70% of the calories consumed is used for this. The rest you burn off with exercise!|
