Effect of a high-protein, very-low-calorie diet on body composition and anthropometric parameters of obese middle-aged women. 1987

K Barrows, and J T Snook

Effects of a very-low-calorie (420 kcal/day), high-protein diet (70 g/day) and realimentation on weight and body composition of 15 obese, middle-aged women were examined in a 4-6 mo study. Mean weight loss was 20.5 kg (1.1 kg/wk). Fat accounted for 83% and lean body mass (LBM) for 17% of total body weight loss. Multiple regression equations estimated from anthropometric measures were developed to predict the body density of obese individuals both before and after weight loss. Best predictors of body density in obese women before and after weight loss were circumference measurements in the trunk area. Nine previously published population specific and generalized equations for predicting body fat in women were not strongly enough correlated with body fat values obtained by densitometry in this study to be of use clinically.

UI	MeSH Term	Description	Entries
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D009765	Obesity	A status with BODY WEIGHT that is grossly above the recommended standards, usually due to accumulation of excess FATS in the body. The standards may vary with age, sex, genetic or cultural background. In the BODY MASS INDEX, a BMI greater than 30.0 kg/m2 is considered obese, and a BMI greater than 40.0 kg/m2 is considered morbidly obese (MORBID OBESITY).
D012044	Regression Analysis	Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.
