Purpose:

The purpose of this study is compare the effects of consuming glucose- and fructose-sweetened beverages on appetite, body weight, body fat, and the amount of energy the body burns as well as effects on blood pressure, hormones, blood triglycerides and cholesterol, and the body's sensitivity to the insulin.


Study summary:

The study is designed as a prospective, blinded diet intervention study during which the participants consume either fructose- or glucose-sweetened beverages (25% of energy) with meals. Experimental procedures, including 24-hour serial blood sampling, 26-h stable isotoped infusions, post-heparin blood collection, gluteal biopsies, metabolic rate monitoring, computed tomography scans of the abdomen, and Oral Glucose Tolerance and Disposal Tests, are performed during baseline and at the end of a 10-week intervention period at the UC Davis School of Medicine/Sacramento Veterans Affairs Medical Center Clinical Research Center (CCRC). During the 2-week inpatient baseline period, subjects are served energy balanced diets containing 15% of energy as protein, 30% as fat, and 55% as complex carbohydrate. Following the baseline period, the subjects reside at home for 8 weeks and consume their usual ad libitum diet along with 25% of energy requirements as fructose- or glucose-sweetened beverages. Subjects then return to the CCRC for the 2-week inpatient intervention period at the end of the study and are served energy-balanced diets containing 15% of energy as protein, 30% as fat, 30% as complex carbohydrate and 25% of energy as fructose- or glucose-sweetened beverage.
