Title: Improvement of Biochemical Markers After Reduction of Artificially Sweetened Beverages Consumption. A Clinical Randomised Trial
Brief Summary: The consumption of artificially sweetened beverages increases glucose and insulin concentrations in blood, body weight and waist circumference. However, the effect of restricting the consumption of these beverages on metabolism is unknown. Our objective is to evaluate the effect of reducing artificially sweetened beverages consumption on the metabolism of overweight and obese young adults. A randomized, blind, controlled 12 week clinical trial will be performed on overweight and obese young adults. Young adults, consumers of artificially sweetened beverages, will be randomly assign to either Control group (no changes in their alimentary habits) or Intervention group (no intake of artificially sweetened beverages). The percentage change between 0 and 12 weeks of anthropometric variables, fasting plasma concentrations of glucose, triglycerides, insulin and cholesterol will be calculated and compared.
