Describe the role of diet in preventing underweight, overweight, and obesity.

The point of a healthy diet is to find a balance to a healthy weight. According to a person age, height and weight will and can determine your status on the BMI chart. The normal weight range on the BMI chart is 18.5-25. Anything under or over those numbers are considered under and overweight. Once the number increase to 30 and above you are label as obese. The classification of obese can range up to class lll, that is 40 and above. By eating three healthy meals and two healthy snacks a day can prevent the issues of underweight, overweight, and obesity. Skipping meals can result in improper weight loss, and a large portion of unhealthy meals can lead to excessive weight gain, which can eventually lead to obesity if not in control of your eating habits. “BMI is a person's weight in kilograms divided by the square of height in meters. BMI does not measure body fat directly, but research has shown that BMI is moderately correlated with more direct measures of body fat obtained from skinfold thickness measurements, bioelectrical impedance, densitometry (underwater weighing), dual energy x-ray absorptiometry (DXA) and other methods.” (http://www.cdc.gov/healthyweight/assessing/bmi/adult_bmi/)
