Reduction of Sweetened Beverages and Intrahepatic Fat

Not Applicable

Completed

• Conditions: Obesity; Metabolic Syndrome; Dyslipidemia

• Registration Number: NCT01394380
• Lead Sponsor: University of Lausanne

Brief Summary

The study will enroll 68 overweight male and female subjects with a high (\> 2 3dl-can soda/day) consumption of sweetened beverage per day. After a run-in period of 4 weeks, subjects will be randomized to either a 12-week intervention arm in which sweetened beverages will be replaced by artificially sweetened, calorie-free beverages, or to a control arm. The following measurements will be performed at the end of the run-in period and at the end of the intervention period

* intrahepatic fat concentration

* visceral fat volume

* changes in day-long metabolic profile from baseline(plasma glucose, insulin, and triglyceride concentrations)

* changes in food intake and daily energy, carbohydrate and sugars intake from baseline

Primary Outcome Measures

Name	Time	Method
changes in intrahepatic fat concentration	at the end of run-in and after 12 weeks intervention/control	intrahepatic fat content measured by 1H-MRS

Secondary Outcome Measures

Name	Time	Method
changes in food intake from baseline	at the end of the run-in period and after 6, and 12 weeks of intervention/control	Total energy intake, total carbohydrate intake, and total sugars intake will be evaluated by 3-day food record
changes in visceral fat volume	at the end of run-in and after 12 weeks of intervention/control	Visceral fat volume measured by MRI
changes in day-long metabolic profile	at the end of run-in and after 12 weeks of intervention/control	Plasma glucose, insulin, non-esterified fatty acids, and triglycerides will be measured at 2-hourly intervals between 7:00 am and 5:00 pm. Participants will be fed standardized meals and either sweetened or artificially-sweetened beverages according to randomization
